What is a sales intelligence platform?
A sales intelligence platform finds the companies and people you could sell to and gives you a way to reach them: a verified work email, a phone number, and ideally a reason to get in touch now. That's the whole promise. The trouble is that products doing very different parts of that job all share the same label. G2 alone counted 601 products in its sales intelligence category in October 2026 (Supered), and they don't all do the same thing.
It helps to sort them by the job they actually do:
- Contact databases rent you access to one company's records of people, with their email addresses and phone numbers. Apollo, Lusha, RocketReach, Cognism, and ZoomInfo work this way.
- Multi-source enrichment tries one database, and when it comes back empty, tries the next. Clay is the best-known example.
- Research and timing tools tell you what's happening at the accounts you care about, so you know whom to contact this week and what to say. LinkedIn Sales Navigator, Salesmotion, and 6sense sit here.
- Platforms that do the prospecting work decide whom to contact, check the details, write the message, and send it. Kite, HubSpot's prospecting agent, and Amplemarket sit here.
Most of the lists that rank for this search are written by vendors ranking themselves first for enterprise sales teams. A small team has a different problem. You probably don't have a sales operations person or a row of reps working a database all day. Your scarce resource is hours, and building a list by hand eats them. Anna Demerchian, who launched outbound at the design agency Eleken, put it plainly: "It was really hard to actually do proper outreach because you were focusing so much on building the list instead of messaging people" (Amplemarket).
The data itself is also less of a moat than it used to be. HubSpot's prospecting agent sources contacts from ZoomInfo, Apollo, Surfe, and Seamless (HubSpot). Lusha became a step inside Clay's enrichment chain in March 2026 (Supered). Apollo and Clay are both built into Kite. When the same records flow through several products, what you're really choosing is how much of the work around them you want to hand off.
That's the order of this list. It starts with the platforms that do the prospecting work for you, moves to the databases and research tools you'd use if you do the work yourself, and ends with two well-known platforms a small team can skip for now.
Platforms that do the prospecting work for you
These platforms take a goal, such as "find heads of marketing at Series B SaaS companies and get them talking to us," and carry it from the list to the sent email. They're the best fit for a team that needs outbound to happen but can't give it a full-time person.
1. Kite
- Starting price
- Free plan; Growth $100 a month per workspace
Kite is an AI marketer. It researches your business, builds a growth strategy, and ships the work that brings you new customers. Prospecting is one of the jobs it owns, and it handles the whole chain: deciding who belongs on the list, finding them, checking them, writing to them, and following up.
The work starts from a plain request in the Kite web app or in Slack, such as "Find 100 ecommerce brands that would be a good fit for us." Kite already knows your positioning, ideal customer profile, and existing customers from its research on your business, so it proposes the audience, the criteria, the exclusions, and the list size, and it waits for your approval before the research begins (Kite). From there, it works through the list in order:
- It searches for companies by industry, headcount, location, revenue, funding, and the technology they use.
- It checks for recent events, such as a funding round, a hiring push, a product launch, or a leadership change, and moves those companies up the list because they give you a reason to reach out now.
- It finds the right people at each company by title, function, and seniority, then confirms each person still holds that role at that employer using current public profile data.
- It scores every prospect from one to five against your criteria and writes a short explanation of each score.
The data comes from more than 20 built-in sources, including Apollo for company and people search, Clay for enrichment, PredictLeads for company events, and Crustdata for hiring and funding data. They run on Kite's own access, so you don't need a separate Apollo or Clay subscription to start.
What separates Kite from a database is what happens after the list. It writes each email one at a time from research on that person and company, in your brand voice, and a prospect who scores low doesn't get one (Kite). It sends from a Kite-managed team address or through your own email platform, follows up on the cadence you choose, drops anyone who replies, and reports which messages landed, which failed, and which drew a reply. Connect your CRM and it creates the records there. Connect your own Apollo account and it can enroll approved prospects in your Apollo sequences (Kite).
By default, Kite proposes the audience, the message angle, and the follow-up schedule in the thread, and it sends once you approve. Teams that have seen its work can switch it to act first (Kite docs). Kite's outreach runs by email, so a team that sells mainly by phone will still want a dialer. Pricing is per workspace rather than per seat: there's a free plan, Growth costs $100 a month and includes $100 in AI credits, and Business is custom (Kite pricing).
Kite is the strongest fit when you want outbound handled the way a capable hire would handle it, from the list through the follow-up, without buying and running a stack of data tools yourself.
2. HubSpot's prospecting agent
- Starting price
- $1 per recommended lead in HubSpot Credits, on a paid Sales Hub plan
HubSpot's prospecting agent lives inside Sales Hub and works from your CRM. You build "plays," each with a target segment, a persona, and the signals to watch, and the agent monitors those companies for events like a funding round, a product launch, or a visit to your website. When a company shows a signal, it suggests contacts, explains the reason to reach out, and drafts the email (HubSpot Knowledge Base). New contacts come from one connected provider at a time, such as Apollo, ZoomInfo, Surfe, or Seamless.
You choose how much it sends on its own. With "Review emails" on, each message waits for the rep to approve it, and with "Send without review" the agent sends within the limits you set. A three-person BDR team lead wrote on HubSpot's community site that the agent pulled in the detail their reps used to spend 15 minutes digging for on each contact, including recent org changes and the contact's own LinkedIn posts (HubSpot Community).
Cost is the thing to plan around. HubSpot prices the agent at $1 per lead it recommends outreach for, paid in HubSpot Credits, and it's available on Starter, Professional, and Enterprise (HubSpot). In practice, that same community post reports about 100 credits per contact, so the 5,000 credits included with their Enterprise plan covered about 50 emails. A HubSpot partner reported burning through 20,000 credits in its first 30 days by running the agent across every segment at once (Growth Operations Firm). Sales Hub Professional starts at $90 to $100 a seat a month, depending on billing, plus a one-time $1,500 onboarding fee (HubSpot).
It's a good fit for a team whose contacts and deals already live in HubSpot and whose reps want drafts they can edit and send. It stops at HubSpot's edge, so the rest of your marketing isn't part of its picture. See the Kite vs HubSpot Breeze comparison for how the two approaches differ.
3. Amplemarket
- Starting price
- $600 a month, annual term, two users
Amplemarket is a full sales platform with its own database of contacts, multichannel sequences, and an assistant called Duo Copilot. Every 24 hours, Duo looks for people worth contacting based on signals you care about, such as a past champion who changed jobs or someone who left a negative review of a competitor, then hands the rep a drafted sequence across email, social, calls, WhatsApp, and other channels (Amplemarket). The rep sends it or dismisses it, and Duo learns from those choices.
Amplemarket's own case study about Eleken reports that two SDRs booked four qualified opportunities and closed a deal within 21 days of starting, with a 40% reply rate on leads Duo recommended (Amplemarket). Those are vendor-published figures from one customer, but they show the intended workflow: the platform picks the people, and the rep spends time on the conversation.
The Startup plan costs $600 a month on an annual term and includes two users and 27,000 contacts. Every plan includes a free trial (Amplemarket). That makes it a $7,200-a-year commitment before extra seats, which fits a founder-led sales team that calls and uses social channels as well as email. A team that wants outbound handled alongside its website, content, and email marketing will get more from an AI marketer than from a sales seat.
Contact databases: where the emails and phone numbers come from
These products sell access to records of people and companies. You search, you reveal an email or phone number, and you spend a credit. They're the right buy when someone on your team will do the prospecting and just needs the raw material.

4. Apollo
- Starting price
- Free; $49 a seat a month billed annually
Apollo is the usual first tool for a small team because it puts a large database, email sequences, and a dialer on one bill. The free plan gives each seat 900 credits a year, granted monthly. Paid seats cost $49 (Basic), $79 (Professional), or $119 (Organization, with a three-seat minimum) a month on annual billing, with 30,000 to 72,000 credits per seat per year. An email costs 1 credit and a phone number costs 8 (Apollo).
On Professional and Organization, Apollo also runs scheduled agents. A lead discovery agent finds prospects that match your ideal customer profile and surfaces the strongest, a sequence creation agent recommends and builds outbound sequences, and an optimization agent watches your live sequences and proposes one change at a time (Apollo Knowledge Base). You pick the prospects and approve each launch.
Two things trip up small teams. First, unused credits expire at the end of each billing cycle with no rollover, and overages cost $0.20 a credit in blocks of 250, so the smallest top-up is $50. Second, "verified" doesn't mean certain. A reviewer at Salesforge, which sells a competing data product, ran 100 Apollo-verified contacts through a second verifier and 27 came back flagged. Of the 73 he emailed, 6 still hard-bounced, and the same search across Europe produced far fewer usable contacts (Salesforge). His verdict still holds for most readers here: "Apollo is the right first tool for most small teams."
Apollo is also one of the data sources built into Kite, so a Kite team gets Apollo search and enrichment without its own Apollo seat.
5. Lusha
- Starting price
- Free; $37.45 a month billed yearly
Lusha is a self-serve contact database best known for its browser extension, which shows a person's email and phone number while you're on their LinkedIn profile, a company website, or your CRM. The free plan includes 40 credits a month with no credit card. Paid plans billed yearly start at $37.45 a month (Starter, 4,800 credits a year), then $52.45 (Pro) and $299.95 (Premium, with five seats) (Lusha). An email costs 1 credit and a phone number costs 5.
Part of Lusha's data comes from its free members, who share their business contacts' details, taken from the email signatures in their work inboxes, in exchange for extra credits (Lusha). In one vendor-run test of 500 contacts across regions, Lusha's emails passed a deliverability check 87% of the time (Saleshandy).
Lusha fits a founder or single rep who looks up people one at a time while browsing. The credit pools are small for list building at volume, and on annual plans unused credits reset at the end of the year.
6. RocketReach
- Starting price
- $399 a year, email only
RocketReach sells a large people database at flat annual prices. Essentials costs $399 a year for email only, Pro costs $899 a year and adds mobile and direct phone numbers, and Ultimate costs $1,699 a year with more exports and intent data (RocketReach). A lookup only counts when RocketReach finds and verifies a contact, and a free account comes with five lookups.
Its Autopilot feature pulls a set number of new contacts from a saved search on a schedule and can send one email from your template to each verified contact. It sends only to addresses graded A or A-, spaces sends 45 seconds apart, and caps at 500 emails a day to protect your mailbox (RocketReach Knowledge Base). Follow-up sequences from Autopilot aren't available yet.
The data is the weak spot. RocketReach scored lowest of the five providers on this list in Saleshandy's test, with 74% email deliverability and a 10% bounce rate on a live send (Saleshandy), and one r/sales commenter put its phone accuracy at "about 50-60 percent of the time" (Reddit). It fits occasional lookups at a predictable price more than it fits a team building lists every week.
7. Cognism
- Starting price
- Quote only; five seats included
Cognism is the specialist for teams that call into Europe. Its top package includes mobile numbers that people have verified by phone, and it checks records against 14 international Do Not Call lists and applies GDPR rules (Cognism Help Center). Its Pro plan adds buying intent from Bombora data. A reviewer who used it for 90 days on outbound to mid-size European companies said about 9 out of 10 phone-verified numbers reached the right person (FahimAI), and Cognism had the highest mobile connect rate, 43%, in Saleshandy's test.
Cognism doesn't publish prices, and both of its plans include five seats (Cognism). Vendr's purchase data, as reported by Supered, puts the median contract at $32,750 a year (Supered). That's a mid-size team's budget. A small team selling into Europe by phone may still find it worth the money, and anyone else will get more from Apollo or Lusha.
Enrichment across many sources
When one database leaves too many blanks, the fix is to ask several in turn. That's what this group does.

8. Clay
- Starting price
- Free; $167 a month billed annually
Clay checks one data provider for an email or phone number, and if it comes back empty, moves to the next, paying only for the lookups that run. It draws on a marketplace of more than 150 data partners and adds Claygent, an AI agent that does web research for each row, such as finding a company's current CEO or writing an opener from recent news (Clay).
The coverage gain is real. Okane Land tested Clay's email chain on 50 US SaaS marketing leads, and it found a valid work email for nine of every ten, with the fifth provider in the chain finding one address the first four missed. The reviewers call that the top of the range and cite an independent test of 200 harder prospects that landed between 40% and 78% (Okane Land). Phone numbers cost about ten times as much as emails.
Clay has a free plan with 500 actions and 100 data credits a month. Paid plans start at $167 a month for Launch and $446 for Growth on annual billing, or $185 and $495 on Clay's monthly figures (Clay). The bigger cost is learning it. Okane Land's reviewers advise a week of real use before it pays back, and they say that for a few dozen leads a month, "a $30 Apollo or Instantly plan does the job with a fraction of the learning curve."
Clay is the right step up when a single database leaves too many rows empty and someone on your team will learn the tool. Clay is also built into Kite for enrichment, so Kite can fill in missing emails and company details through Clay without you building the tables.
Research and timing for the accounts you already chose
These tools are strongest at telling you whom to contact and why. They don't supply much contact data themselves, so you pair them with a database or a platform from the first group.
10. Salesmotion
- Starting price
- $85 a month
Salesmotion watches a list of target accounts for events like leadership changes, funding, hiring surges, and earnings calls, then writes research briefs and drafts outreach for each one. The Individual plan costs $85 a month, billed monthly, and covers one user, 100 monitored accounts, and 200 contact credits a month for emails and direct dials (Salesmotion).
It doesn't send anything. A review by SyncGTM, which sells a competing signal tool, notes there's "no built-in email sequencing, no LinkedIn automation, no dialer," so each draft has to be copied into your email or another tool. It also says there's no published price beyond one seat, and CRM connections come only with a custom plan (SyncGTM). Salesmotion fits a founder or account executive who already knows their 100 target accounts and wants to know when to act on each one.
Enterprise platforms a small team can skip for now
These two show up on nearly every list of the best sales intelligence platforms. They're built for larger sales organizations, and their contracts show it.
11. ZoomInfo
- Starting price
- Lite is free; paid plans quoted annually
ZoomInfo has the deepest North American database on this list, with more than 500 million contacts and 100 million companies, and layers on intent data and website visitor identification (ZoomInfo). Its paid plans are custom-quoted, billed annually upfront, and come with a minimum number of seats. Vendr's data, as reported by Supered, puts the median buyer at $33,500 a year, and Supered also reports that ZoomInfo's CEO told staff in May 2026 the company was "reducing the resources we allocate downmarket" (Supered).
The useful part for a small team is ZoomInfo Lite, a permanent free tier with no card and no contract. It includes 10 credits a month, the browser extension, email sending, a HubSpot connection, and up to 10 website visitor reveals a day (ZoomInfo). Try Lite if you're curious, and wait on the paid contract until you have several people prospecting full time.
12. 6sense
- Starting price
- Quote only
6sense predicts which accounts are researching your category and ranks them for your sales team, using its own intent data, account summaries, and predictive scores. It publishes no prices and asks visitors to book a demo (6sense), and its free Sales Intelligence plan ended on August 12, 2026 (6sense RevCity).
Superframeworks, writing for founders, estimates contracts at $55,000 to $130,000 or more a year and says that below about five SDRs, the list of accounts showing intent "goes stale before anyone touches it" (Superframeworks). That's the right way to think about it. Intent data only pays off when someone can act on it the same day.

How accurate is sales intelligence data?
Every provider claims high accuracy, and third-party tests keep finding a gap. Apollo markets 97% to 98.5% accuracy, yet the Salesforge reviewer found 27 of 100 "verified" contacts flagged by a second checker (Salesforge). Saleshandy, which sells its own data product, ran the same 500 contacts through ten providers in June 2026 and measured the share of emails that passed a deliverability check. The five on this list scored as follows (Saleshandy):
- Cognism: 91%
- Lusha: 87%
- ZoomInfo: 84%
- Apollo: 82%
- RocketReach: 74%
Phone numbers were weaker across the board, with mobile connect rates between 20% and 43% for these five. The same author notes that contact data decays by about 2% a month as people change jobs. Pulling from several sources at once helps, which is why Clay's chain of providers found more emails than any single one in Okane Land's test.
The practical lesson is to check before you send. Run 100 contacts from your own target market through any platform you're considering, and verify the emails before a campaign goes out. This is also why Kite confirms each person's current role and employer from public profile data before it writes to them, and finds and verifies a work email when a list arrives with missing or stale addresses.
How to choose the right one for a small team
Start with one question: will someone on your team spend real hours each week building lists and writing outreach?
- If nobody will, choose a platform that does the work. Kite builds the list, writes each email from research, and sends after you approve, all from the Kite web app or Slack, with Apollo and Clay already included.
- If your team lives in HubSpot and your reps want drafts to edit, HubSpot's prospecting agent keeps everything in the CRM. Budget carefully for credits.
- If you run founder-led sales across email, phone, and social channels and can commit $7,200 a year, Amplemarket gives your reps daily picks and ready sequences.
- If you'll do the prospecting yourself, start with Apollo's free plan or Basic seat. Add Clay when single-source coverage leaves too many blanks, Cognism when you call into Europe, and Sales Navigator when your buyers are active on LinkedIn.
- Leave ZoomInfo's paid plans and 6sense until you have several people prospecting full time.
Then check three things before you pay. Find out whether unused credits expire each month. Read the contract for annual terms, minimum seats, and renewal increases. And test the data on your own market first, because a list that bounces costs you sender reputation as well as money.
Common questions
Is there a free version of ZoomInfo?
Yes. ZoomInfo Lite is a permanent free tier with no credit card, no annual commitment, and no expiration date. It includes 10 credits a month (25 with ZoomInfo's Community Edition), contact and company search, contact exports, the browser extension, email sending, and a HubSpot connection (ZoomInfo). Ten credits is enough to judge the data, not to run a campaign.
What are good ZoomInfo alternatives for a small business?
Apollo is the closest all-in-one alternative at a small-team price, with a free plan and paid seats from $49 a month. Lusha and RocketReach are cheaper self-serve options for looking up contacts, Cognism is the alternative for European data, and Clay combines many providers when one isn't enough. If what you actually want is the prospecting done rather than a database to work, Kite and HubSpot's prospecting agent both draw on databases such as Apollo and do the work on top of them.
What's the difference between sales intelligence and sales engagement?
Sales intelligence tells you whom to contact and how to reach them. Sales engagement is the sending: email sequences, call tasks, and follow-ups. The line has blurred, since Apollo, Amplemarket, and HubSpot's prospecting agent now do both. Salesmotion, Sales Navigator, and Cognism still lean toward intelligence and leave most of the sending to you, while Kite carries a prospect from the list all the way to a tracked reply.
Does a small team need to pay for a sales intelligence platform at all?
Not always. A sales operations lead at a five-SDR startup recommends a lean setup of Apollo or Hunter plus an email verifier for about $60 to $130 a month (Medium), and Apollo's and ZoomInfo's free tiers cover light, occasional prospecting. You need more when the hours spent building lists start crowding out the conversations. At that point, the choice is between a bigger database you'll work yourself and a platform that does the work for you.
