Why teams choose AgentData
10 customer lists for $99 a month, not $495
BuiltWith Basic stops at 2 technologies for $295 a month; lists for more take Pro at $495.[1] AgentData Pro covers 10 for $99 a month.[10] If you sell against a handful of products, that is the whole job on the smaller bill.
The new customers, not just the old ones
We flag a company as soon as we see it start using a product, on a live feed of new customers and in a weekly email on Pro. That is when a company is choosing tools, and the best moment to reach it.
Business software, not website plumbing
We track 4,281 technologies across 34 million company websites and put CRMs, help desks, email, payments and chat first, so a list is companies you can sell to rather than sites running a font or a code library.[9]

Proof on every row
A list is only useful if your team believes it. Every company on an AgentData list shows how we know it uses the product, and when we first and last saw it. Some tools show up in a website’s code; others only in the domain’s email and verification records, which is how we find help desks, email platforms and sign-in tools a homepage never mentions.

Where BuiltWith is stronger
BuiltWith, founded in 2007, is the reference database for web technology: 128,007 technologies across 551,540,987 root domains, with trend history, alerts when sites stop using a technology, contact names and titles, and Salesforce, HubSpot and Dynamics 365 connections.[4][1][3] If you research the whole web, or need history or churn alerts, it is the better tool.
VerdictBuiltWith is the encyclopaedia. AgentData is the sales list: the customers of the B2B products you sell against, with proof, and the new ones every week, for $99 a month instead of $495.
