About Flatfile
Helping organizations work with customer data
Flatfile builds software that helps organizations work with customer data. To reach the right buyers in niche and diverse markets, the team needs fast, accurate market maps and the ability to pinpoint decision-makers at those accounts.
Flatfile uses Exa's Websets API for internal business intelligence, generating targeted cohorts of similar companies per vertical and identifying the right contacts, replacing manual research loops with a single enriched call.
The Challenge
Missing details and manual search
Traditional list vendors and classification systems miss long-tail companies, especially when a firm straddles services and software or sells into an uncommon niche. They faced key obstacles:
- Incomplete coverage: Purchased lists often omit known in-market firms, forcing manual, multi-step web research
- Manual research loops: Hours spent in sourcing and setting up data partnerships for each new vertical
- Cost inefficiency: Spending hundreds of thousands to assemble comprehensive market maps
The Solution
Automated market intelligence with Websets
Flatfile implemented Exa's Websets API to automate their market research and business intelligence workflows.
Company research
Produce lookalike cohorts to expand target lists across niche verticals with complete coverage
People research
Surface relevant contacts at those companies to accelerate business development efforts

Results
Game-changing scale and efficiency
Flatfile deployed the Websets API and achieved significant improvements in their market research capabilities.
- Complete coverage: Found companies that didn't show up anywhere else in their research stack
- Massive efficiency gains: One enriched call replaces 15–20+ manual iterations with comparable quality
- Cost reduction: Delivers for a few dollars what they'd been spending hundreds of thousands to assemble
"When we saw companies show up in Exa that we hadn't found anywhere else, we knew it was our best option. It delivers, for a few dollars, what we'd been spending hundreds of thousands to assemble. ::: Exa's websets let us automatically zero in on the right results first, then enrich across as many attributes as we need, all in one go. It's game-changing and allows us to do this at a scale that simply wasn't possible before - manually or automatically. :::"— Lion Hummer, Technical chief of staff, Flatfile
