It then narrows that list to real companies that fit your customer profile and scores each one from one to five. - Kite reads any company's technology profile in BuiltWith, both current and past. That shows which analytics, advertising, email, chat, and ecommerce tools a prospect or competitor runs, and when each one appeared or disappeared. - Kite also uses BuiltWith to find online stores selling a particular product, match social media profiles to company websites, and pull financial data on US and UK companies. - You connect your own BuiltWith account with an API key, so you'll need a BuiltWith plan that includes API access. Kite uses BuiltWith for research, and the lists it builds go to Kite, your CRM, or a spreadsheet. Capabilities verified August 26, 2026. ## How an AI marketer uses BuiltWith BuiltWith is a technology lookup service. It crawls websites and records what each one loads, such as the ecommerce platform, the analytics and ad tags, the chat widget, the email signup form, and the payment scripts. That gives it two views of the web: the full technology profile of any one site, and a list of every site where it has seen a given technology. An AI marketer uses both views. The list answers "Who runs the product we work with, or the one we replace?" The profile answers "What does this company already use, and what does that tell us about how to pitch it?" The real work is turning an export of thousands of domains into a short list of companies worth contacting, each with a reason. Kite does that work through your connected BuiltWith account. It decides which BuiltWith searches your goal calls for, reads the results, and carries them through to a scored list, a competitor report, or an outreach campaign. ## Marketing jobs Kite can do with BuiltWith BuiltWith gives Kite lists of sites by technology, the technology profile of any one site, and a handful of lookups that fill in the gaps around them. The jobs below start with finding accounts, move to researching them, and end with sizing a market. ### Find companies that run a specific technology Kite builds prospect lists from BuiltWith's list of every website using a technology. Say you sell a reviews app that works with Klaviyo. Kite asks BuiltWith for the sites running Klaviyo and reads each entry's domain, company details, and two dates: when BuiltWith first detected Klaviyo on the site and when it last saw it there. Those dates do a lot of the sorting. A recent last-seen date means the store still runs Klaviyo, so Kite keeps it. A recent first-detected date means the store adopted Klaviyo in the last few weeks, which is a good moment to reach out because they're still setting it up. When you want companies that just left a competitor, Kite reads the same dates the other way and looks for the competitor's product disappearing from a site. From there, Kite checks each company against your ideal customer profile, removes your current customers and competitors, and scores the rest from one to five with a one-line reason. You can also put the search on a weekly schedule, and Kite brings you only the companies that started using the technology since the last run. ### Read a company's technology profile, current and past Kite looks up any domain in BuiltWith to see the technology that site runs today and what it ran before. That profile shows up in three kinds of work. - **Account research.** Before a sales call or an outreach email, Kite reads the prospect's stack so the message can mention the tools they really use, like the HubSpot forms on their demo page or the Segment script behind their analytics. - **Competitor research.** The ad tags on a competitor's site show which networks it advertises on. A newly added A/B testing tool means it has started running experiments, and a switch from one email platform to another tells you its email program is changing. - **Checking a list you already have.** When you hand Kite 400 target accounts from your CRM, it looks up each domain and tells you which ones run the technology you care about. For a long list, it prepares the domains as a file for BuiltWith's bulk lookup. For a quick read, Kite can also pull a lighter snapshot of a site. It shows how many technologies the site runs in each category, such as analytics or advertising, and when each category last changed. That's enough to tell whether a company has invested heavily in its marketing stack before Kite reads the full profile. ### Find online stores that sell a particular product Kite searches BuiltWith for ecommerce sites selling a specific product. If you sell a shipping insurance app for furniture retailers, Kite can find the stores that list standing desks or sofas and build the prospect list from them. It can also read the product listings on a single store's domain, which helps when you're researching what a competitor or a retail partner carries. ### Clean up and complete a company list Kite uses three smaller BuiltWith lookups to turn a messy list of domains into a clean list of companies. - **Redirects.** BuiltWith shows which domains forward to which, now and in the past. Kite uses that to collapse a brand's regional sites and old domains into one company, so nobody on your team emails the same company three times. - **Social profiles.** BuiltWith matches social media profile URLs to the websites behind them. When you start from a list of Instagram or X accounts, such as brands from an influencer search or an event's sponsor list, Kite finds each company's website and can then read its technology. - **Financial data.** For companies registered in the US or UK, BuiltWith supplies financial data on the business. Kite uses it to check whether a company is the right size before it adds the company to your list. ### Size a market by technology adoption Kite uses BuiltWith to measure how many companies run a technology and how that's changing. Say you're deciding whether to build a Webflow integration next. Kite counts the sites running Webflow in your target market and reads BuiltWith's long-run technology usage data, which goes back to 2000, to see whether adoption is growing or flattening. It brings you the numbers alongside a recommendation, so the decision rests on the actual size of the audience. ## What Kite reads in BuiltWith BuiltWith is a research source for Kite. Everything Kite does with it is a lookup, and the lists, scores, and reports that follow land in Kite, your CRM, or a spreadsheet. The data Kite reads includes: - **Technology lists.** Every site BuiltWith has detected running a given technology, with the domain, company details, and the dates the technology was first and last seen. - **Technology profiles.** The current and past technology on one domain, across categories such as ecommerce, analytics, advertising, email, chat, and payments. - **Technology snapshots.** The number of technologies a site runs in each category and when each category was last updated. - **Product listings.** Online stores selling a specific product, and the products listed on a single store's domain. - **Redirects.** The domains a site forwards to or receives traffic from, now and in the past. - **Social profile matches.** The website behind a social media profile URL. - **Financial data.** Financial details for companies registered in the US or UK. - **Usage history.** BuiltWith's long-run record of technology usage, going back to 2000. ## How Kite connects to BuiltWith Kite is an AI marketer. It researches your business, builds a growth strategy, and ships the work that brings you new customers. Add an API key for your BuiltWith account. Kite uses the access granted to that key. BuiltWith isn't built into Kite, so the lookups run through your own BuiltWith plan. Once it's connected, start with a goal rather than a technology name. You might ask, "Find US ecommerce brands on Shopify that use Klaviyo and look like a fit for us." Kite already knows what you sell and who your best customers are, so it proposes the BuiltWith technologies to search, the company size and location to aim for, and where the finished list should go. You confirm or adjust the plan, and Kite starts. If you want the results in HubSpot, a Google Sheet, or Airtable, connect that account too. Otherwise the list arrives in the conversation as a table and a file. ## How-to guides using BuiltWith - [How to find companies using a specific technology with BuiltWith](/how-to/find-companies-using-a-specific-technology-with-builtwith.md) Kite turns the exact technology you're targeting into BuiltWith searches, keeps only the sites still running it, groups domains into real companies, scores each one against your customer profile, and delivers the accounts to your CRM or a spreadsheet. ## Where BuiltWith fits in Kite's marketing work ### [Build qualified B2B lead lists](/use-cases/build-b2b-lead-lists.md) BuiltWith supplies the accounts when the best way to describe your buyer is the technology they run. It tells Kite which companies use the platform you work with or the competitor you replace. Kite then finds the right people at each company through its built-in [Apollo](/integrations/apollo.md) connection, adds their work email and LinkedIn profile, and scores each person from one to five. From there, it can add the leads to your CRM or write and send the outreach. ### [Run an in-depth competitor analysis](/use-cases/competitor-analysis.md) BuiltWith shows Kite what a competitor runs on its website and how that has changed over time. Kite combines that with its research on the competitor's positioning, content, search presence, and ads. When a rival adds a chat tool, switches email platforms, or starts advertising on a new network, Kite explains what the change suggests about the rival's plans. ## Limits and product-specific details - **BuiltWith sees what a website loads.** It's strongest for technology that shows up on a public site, such as ecommerce platforms, analytics, ad tags, chat, and email forms. Software that never touches the website, like most internal tools, generally doesn't appear in BuiltWith's data. - **Financial data covers the US and UK.** For companies registered elsewhere, Kite checks size and revenue with its built-in sources instead. ## Common questions ### Can Kite check what technology a website uses without a BuiltWith account? Yes, for the most common marketing tools. Kite can read a company's homepage and spot widely used analytics, ad tracking, A/B testing, and email tools without any connected account. Its built-in [Crustdata](/integrations/crustdata.md) connection also covers the technology companies use when Kite searches for prospects. Connecting BuiltWith adds a site's full technology profile, its history, and the list of every site running a technology. ### Where do the contacts on a BuiltWith list come from? Kite uses BuiltWith to find and qualify the companies, then finds the people through its built-in contact sources. It searches each company by title and seniority and adds each person's role, LinkedIn profile, and a professional email when one is available. You don't need a separate account for that step.
