Bloomberry vs BuiltWith

1. Technology Coverage: Web vs. Non-Web

BuiltWith specializes exclusively in frontend and web technologies. If you're looking for companies using Shopify, WordPress, or have a Facebook ad pixel on their website, BuiltWith is excellent for this use case. However, if you need data on non-web technologies, Builtwith has almost zero reliable data on it. For example, if you're looking to find customers who use Acumatica (an ERP), Builtwith only has 1 result, a Content Management System allegedly named "MYOB Acumatica" (with 8 live websites), as you can see in the image below.

This is where Bloomberry excels, as we cover 1,100+ products across 180 categories including Acumatica (over 1000+ customers detected), Zoom, Microsoft Dynamics, Slack, and other B2B technologies.

2. Advanced Detection of Tech Adoption

BuiltWith can only detect backend products when companies add tracking scripts to their public websites. Here's the problem: most companies start using products long before they add any tracking scripts — if they ever add them at all (ie. never for products like Acumatica).

For example, Eightfold started using Gainsight (a customer success platform) on September. But BuiltWith never detected it yet on Eightfold.ai. They won't detect it until the company finally adds Gainsight's usage tracking to their website — or never, if they don't bother with tracking scripts. Bloomberry, on the other hand detected that Eightfold signed up for Gainsight on September 18th. We detect these customers when they go live, giving you a 2-3 month head start (or catching customers BuiltWith misses entirely). Why? Because we see the actual adoption, not just the tracking script.

3. Advanced Detection of Churn

BuiltWith has weak detection when a company churns from a product. Their churn detection is limited to checking if a script was removed on websites. For example, if a company cancels their Intercom subscription but leaves the script on their site (a common occurrence), BuiltWith will incorrectly show them as an active user. If you detect their browser's network tab, you'll see Intercom fails to load (because the website unsubscribed), but BuiltWith's data doesn't capture this crucial distinction between "script present" and "actively using."

As a concrete example, Builtwith incorrectly detects Intercom as present in Shaker.io, but we detected it as removed on October 1, 2025. The Intercom tag is present in shaker.io, but it stopped working (returns errors). There's no Intercom widget anywhere on their website. They're no longer a customer, and Bloomberry detected that. See the screenshots below.

4. Data Freshness

BuiltWith's updates can be slower than ideal, especially for companies that frequently update their tech stacks. If BuiltWith tells you a company uses a technology, that might have been true months ago.

This happens because BuiltWith focuses on crawling as many sites as possible. With tens of millions of websites to crawl, they can't revisit the same site as frequently as needed. Bloomberry's approach prioritizes data freshness and real-time signal detection over sheer volume, as we intelligently prioritize websites that have a higher likelihood of adding technologies over smaller sites (ie a random blogger). As an example, as of this writing Builtwith has not detected that coforge.com started using Segment. However, we already detected they started using Segment on Oct 15, 2025 (a week ago).

5. Coverage of Emerging Technologies

BuiltWith has limited data on newer technologies. As of this writing, they have zero data on companies using UnifyGTM and other emerging sales technologies that have raised millions in venture capital and already serve hundreds of paying customers. Bloomberry actively tracks these newer B2B tools as they gain traction in the market. While BuiltWith shows zero UnifyGTM customers, we track 20-30 new UnifyGTM sign-ups every single month.

Can Bloomberry replace BuiltWith?

It depends on your use case. If you just need a list of websites that use a web technology like CMS platforms and advertising pixels, and don't care about freshness, BuiltWith remains the market leader. If you need broader B2B technology intelligence including non-web products and real-time signals, Bloomberry is the better choice.

Does Bloomberry track web technologies too?

Yes, Bloomberry tracks web technologies, such as advertising platforms (ie. Facebook, Twitter, Reddit), martech (Hubspot, Optimizely, VWO), and ecommerce (Shopify, BigCommerce) but it's unique differentiation is its coverage of the full B2B tech stack including non-web products like CRMs, cybersecurity tools, devops platforms, and more.

How does Bloomberry detect real-time purchase and churn events?

Bloomberry uses proprietary detection methods to identify when companies adopt or abandon B2B technologies. This provides sales teams with actionable timing intelligence that static technographic data can't offer.
