A company running Shopify Plus points you to its head of ecommerce, while a company running Marketo points you to its marketing operations lead. - Kite searches your connected BuiltWith account for the companies using the technology, confirms the signal on each site, and finds the people who own that tool through its own Apollo connection. It enriches only the people it chooses. - You end up with a scored list of people at companies that use the technology you care about, each with a work email and its verification status, a LinkedIn profile, and a note on what the company runs and why that makes it a fit. ## How do I find companies that use a specific technology and the right people to contact there? You find companies that use a specific technology by building a list in BuiltWith of the websites where that technology is detected, then using Apollo to find the people at those companies. BuiltWith crawls websites and recognizes the code that tools leave behind, such as a store platform, an analytics tag, a chat widget, or a marketing automation form. In BuiltWith, you pick a technology, filter the list by country and other details, and export it from a paid plan. The list gives you the domains along with the dates BuiltWith first and last detected the technology on each site. In Apollo, you import those domains as companies or search for them, then filter the people there by job title and seniority. Apollo's search shows you names and titles, and you reveal a person's work email by enriching them, which uses Apollo credits. BuiltWith and Apollo don't connect to each other for this job, so the handoff happens through that export and import. Apollo's own company search also has a technology filter, built on its own data, which some people use instead of BuiltWith. BuiltWith tends to go deeper on website technology and its history, which is why teams pair them. Either way, the tools hand you companies and people. They don't tell you which technology signal is worth acting on or who at each company decides what happens to that tool. That judgment is the job. Technology use is useful because it says something specific about a company's needs. A company running a competitor's product may be ready to switch, a company that just added a tool your product works with is a natural fit, and a company that dropped a tool in the last few months is shopping for a replacement. The technology also points to the buyer, because every tool has an owner inside the company. A good result is a short list of people who own the relevant tool at companies that fit your customer profile, with a verified work address and a clear reason to write. Kite does this work for you. It chooses the technology signal, checks it on each company's site, picks the right person at each company, and hands you a list you can contact right away. ## How to get started Start by telling Kite which technology you want to target, in the Kite web app or in Slack. A plain request is enough: > "Find US companies with 50 to 500 employees that run HubSpot Marketing Hub, and get me the marketing operations lead at each one." Kite is an AI marketer. It researches your business, builds a growth strategy, and ships the work that brings you new customers. By the time you ask, it already knows your ideal customer profile, your current customers, and your competitors from that research. It proposes the technologies worth targeting, such as the tools your product works with or the competitors it replaces, along with the industries, company sizes, locations, and the titles it would look for. Confirm the plan or change it, and Kite starts. To search BuiltWith directly, connect your BuiltWith account with its API key. If you don't use BuiltWith, Kite searches for companies by technology through its own Apollo connection and its other built-in company data. You don't need an Apollo account, because Kite has its own Apollo connection built in. Finding and enriching contacts is research, so Kite does it and then shows you the results. It asks for your approval before it sends any outreach. ## How Kite finds technology-qualified companies ### Which technology signal counts? Kite starts by turning "companies that use this technology" into a signal that matches what you sell. There are three useful versions of it, and each leads to a different message: - **Using a tool your product works with.** These companies already have the system your product plugs into, so the pitch is about what you add to it. - **Using a competitor's product.** These companies already pay for the job you do, so the pitch is about what makes yours better. - **Recently added or dropped a tool.** A company that just adopted a platform is setting up the tools around it, and a company that removed one is looking for a replacement. Kite also decides which technologies to exclude. A company that already runs your product, or a tool that makes yours unnecessary, doesn't belong on the list. It combines the signal with the industries, employee counts, and locations from your customer profile. ### Finding the companies in BuiltWith Kite pulls the list of websites using the technology from your connected BuiltWith account, then looks up each website it's considering. The website lookup returns the site's current and past technologies, so Kite can see when the technology first appeared, whether it's still there, and what else the company runs alongside it. For companies in the US or the UK, BuiltWith can also supply financial information on the company behind the site. When you name a best customer, Kite can ask BuiltWith for websites with a similar technology profile, which finds companies built the way your best customers are built. Without BuiltWith, Kite uses its built-in sources for the same search. Apollo's company search filters by the technologies a company uses, alongside headcount, location, revenue, and funding. Kite's other built-in company data covers technology use too, and Kite can read a company's website directly to detect the marketing and analytics tools it runs. ### Which companies are worth contacting? Kite narrows the list before it looks for a single person, so it never spends effort on companies you wouldn't sell to. It removes your current customers, your competitors, and companies outside your profile. It drops sites where the technology hasn't been detected in months, because an old detection often means the company already moved on. Kite then checks that the company behind each website is a real fit. BuiltWith's lists are made of websites, and some of them are agency sites, test stores, or second domains of a larger company. Kite enriches each remaining company in Apollo by domain, which returns its industry, employee count, revenue, funding, and the technologies Apollo has on record. When BuiltWith and Apollo agree that the company runs the technology, Kite treats the signal as confirmed. Apollo also shows a company's open job postings and recent news, and a posting that names the technology, such as a role for a Salesforce administrator, is strong evidence that the tool matters there. ### Who is the right person at each company? Kite picks the person who owns the technology, because that's the person who will feel the problem your product solves. It searches Apollo for people at each company by domain, which avoids mixing up companies with similar names, and filters by job title, seniority, and location. A store platform usually belongs to the head of ecommerce, a marketing automation tool to marketing operations, an analytics tool to the growth or data lead, and a CRM to sales or revenue operations. At a small company, Kite usually goes to the founder or the head of the department instead, because no one there has the specialist title. Apollo's people search can also filter people by the technologies their company uses, including companies that use one tool and don't use another. Kite uses that filter to find, in a single search, the marketing leaders at companies that run a particular platform but not your competitor's product. Apollo's people search returns names, titles, and LinkedIn profiles but not email addresses. Kite enriches only the people it chooses, using Apollo's person enrichment, which returns the work email and its verification status, the current title and seniority, the LinkedIn profile, and the person's employment history. Kite uses that employment history to confirm the person still works at the company in that role, and it drops anyone who has moved on. ### What goes on each contact? Kite records the professional details a salesperson needs and the reason this person is worth contacting. Each contact gets a fit score from one to five with a one-line reason, such as "Marketing operations manager at a 200-person software company that added HubSpot Marketing Hub four months ago and is hiring a lifecycle marketer." When the list runs past about fifteen people, Kite splits it into primary and secondary groups so you know where to start. Kite keeps each email's verification status exactly as Apollo returns it, such as verified or unverified. When no email is available, Kite marks it as not found rather than guessing an address, because a guessed address bounces and hurts the reputation of the domain you send from. Kite includes business details only, so personal email addresses and phone numbers stay off the list. ### What Kite reports back When the work is done, Kite posts the list in the conversation where you asked, as a table you can scan and sort. It says how many websites BuiltWith returned, how many companies it kept and why the rest were dropped, and how many contacts it delivered with a work email. If fewer companies qualified than you hoped, it says so and explains what held the others back, such as a technology detection that was too old or a company too small to have the buyer you described. From there, Kite can save the list to a connected spreadsheet or CRM, such as Google Sheets or HubSpot. It can draft a short first email for each primary contact that opens with the technology the company runs and what your product does with it, and it asks for your approval before anything is sent. If you want to catch companies as they adopt a technology, ask Kite to run the same search every week, and it will skip companies it has already given you. ## What the finished work contains When Kite finishes, you have a list of people who own the technology you care about at companies that fit your profile, with everything you need to write to them. - **Companies.** Each company has its domain, industry, employee count, revenue, location, and the technology that qualified it, with the dates it was first and last detected and the other relevant tools on its site. - **Contacts.** Each person has their name, current title, seniority, LinkedIn profile, work email, and the email's verification status. - **Fit and reason.** Each contact has a fit score from one to five, a one-line reason, and a primary or secondary label. - **Signal notes.** Each company notes why its technology makes it a fit, such as a tool your product works with, a competitor it might replace, or a recent change, along with any job posting that names the tool. - **Next steps.** When you ask for them, the list arrives with draft first emails, or it lands in your connected spreadsheet or CRM for your team to work. ## Common questions ### Do I need a BuiltWith subscription for Kite to find companies by the technology they use? No, you don't need BuiltWith, because Kite can search for companies by technology through its own Apollo connection and its other built-in company data. If your team already pays for BuiltWith, connecting it gives Kite the deeper website history BuiltWith keeps, including when a technology was added or removed. ### How can I check what technology a single website uses? You can check one website by entering its address in BuiltWith's free lookup or by using a browser extension such as Wappalyzer, which shows the technologies on the page you're viewing. Both read the code a site loads, so they find tools that run on the website, such as analytics, chat, and store platforms. Tools a company uses only internally, such as a CRM that never touches the website, often don't show up. ### What are some alternatives to BuiltWith? Common alternatives to BuiltWith include Wappalyzer, which detects website technologies and sells lead lists, and Apollo's own technology filter, which lets you search companies and people by the tools their company uses. Larger sales teams also use technographic data from providers such as HG Insights and ZoomInfo, which add signals beyond the website. ### Can Kite keep finding companies that adopt a technology? Yes. Ask Kite to run the search on a schedule, such as every Monday morning, and each run finds companies where the technology appeared since the last one, picks the right person at each company, and posts the new contacts in the conversation or channel you choose. ## Related pages - **Use case:** Find companies by the software they use (coming soon) - **Use case:** [Build qualified B2B lead lists](/use-cases/build-b2b-lead-lists.md) - **Use case:** Run account-based marketing campaigns (coming soon) - **Integration:** BuiltWith + Kite (coming soon) - **Integration:** [Apollo + Kite](/integrations/apollo.md)
