Get Alerts When It Matters

Bloomberry's Alerts feature sends notifications to your inbox or Slack channel whenever:

  • A new customer signs up for a technology you're tracking (great for competitive displacement or partner outreach)
  • A company churns from a product (perfect timing to offer your alternative)
  • A renewal is approaching (reach out before the auto-renew locks the budget)

What you can do with our data

Find prospects actively buying in your primary (or adjacent) category

When companies make recent purchases, it signals they're in an open buying cycle and willing to try new tools. These prospects have proven they have the budget and have similar problems your product helps solve.

Find prospects that recently churned from competitors

These prospects might be frustrated with their current options and actively looking for something better. They're highly likely to buy your product to replace something they unsubscribed from recently.

Get deep account intelligence

See the recent technology purchases for any prospect. Know what product categories they recently invested in, or churned from, so you're prepared when you meet them.

Find potential churn candidates

Find current customers that recently purchased a product in the same category as yours. Reach out to them to ensure they're not looking for alternative solutions.

Build highly relevant marketing lists

Build lists of companies to advertise on LinkedIn with extremely specific filters like "Find companies that subscribed to a machine learning platform in the past 90 days"

Stack our signals with other 1st or 3rd party signals

Uncover prospects that have extremely high intent such as "attended your webinar" AND "their company churned from a product in your category 3 months ago"

Frequently Asked Questions

Where does your data come from, and how is it different from BuiltWith, Wappalyzer or TheirStack?

Bloomberry tells you which companies just started or stopped paying for any of 1,700+ B2B products. It reads infrastructure signals - what a company sets up when it buys software - rather than website tags or job postings.

Concretely, that means new subdomains, DNS records, certificate transparency logs, and signals specific to how each individual product gets deployed. We crawl websites too, but we go further than checking whether a tag exists - we read the configuration inside script files and check whether they still return a working response. We've built a separate detector for each of the 1,700+ products we cover, so we know what that particular product looks like when it's set up, and we can confirm when it's gone. That's why we can tell you when a company subscribed or churned, not just what's on their website today.

Some of those signals only appear when a product is genuinely deployed. Rolling out an AI assistant or an ERP across an organization usually means verifying a domain for single sign-on or updating email records - public changes that a single seat or a free trial never produces. So when we report an adoption, it generally reflects a real organizational rollout.

Website scanning tells you presence, not timing, and skews toward front-end technologies. Job postings tell you what a company wrote in a job ad, which is why TheirStack scores how likely it is that the company actually uses what it mentioned. We don't use job postings, vendor case studies or product reviews - they're indirect and they lag.

Because we're not limited to website tags, we also cover backoffice products with no website footprint at all: AI products (ie ChatGPT, Claude, Cursor), CRMs (ie Salesforce and Hubspot), project management tools (Jira, Monday) and much more.

Why do you cover fewer products than BuiltWith or TheirStack?

Because we build a separate detection method for each product we cover. Depending on the vendor, that can mean watching for a new subdomain to resolve, reading DNS records, or checking a signal specific to how that one product works. Catalogs with tens of thousands of entries get there by running a single generic check across every JavaScript library, tag and framework on the internet - most of which nobody sells against. We cover the 1,700+ B2B products GTM teams actually build territory and displacement plays around, and for each one we tell you when a company started or stopped paying. We also don't call it churn just because a tag disappeared: we verify the endpoint is genuinely dead first, so a site redesign doesn't show up as a lost customer.

Can you tell me which companies just adopted AI tools?

Yes. We track adoption and churn for AI products the same way we track everything else, with dates attached - including ChatGPT, Claude, Cursor and others across our enterprise AI category. So you can ask questions like "which companies rolled out an AI coding tool in the last 90 days" rather than just "who has an AI vendor somewhere in their stack".

Do you cover newer tools, or just established ones?

Both, and we add new products continuously. We already track adoption for tools that launched recently - RB2B, Unify, Warmly and similar - alongside established categories like CRM and ERP. Legacy technographic databases are built around one fixed detection method, so newer GTM and AI tools tend to arrive late or not at all. If there's a product you need covered that we don't have yet, tell us and we'll usually add it.

How many product categories does your data cover?

We cover 1,700+ products across 190 categories. We cover a broad range of categories from enterprise AI, CRMs, cybersecurity, learning management, sales intelligence, ERPs, and more. You can explore all our categories here.

How many of these subscribe/churn events do you uncover per month?

Our data consists of over 400,000 events every month.

What are the limitations of your data?

While we cover a wide range of categories, there are a few niches where we're not as strong such as edtech. In addition, we do not provide data on the person who was in charge of the purchase/churn event. We only provide data on the companies, not contact information of individuals.

Do you have an UI/app or just an API?

Our data is available through both an UI and an API. You can sign up to browse our data or request an API key here. If you're a platform looking to integrate our signals into your own product, see our API documentation.

Can I get a free trial?

Yes, please fill out this form and we'll email you login details.

Are you a new company? How come I've never heard of you?

Our company Revealera has sold hiring and technology adoption data to some of the biggest hedge funds for the past 5 years, including 3 of the 20 largest funds in the world. We recently launched Bloomberry to bring that data to a different audience: sales, GTM and ABM teams and platforms.
