We built the prospecting tool we couldn't find.
Firmbase started because we kept running into the same problem across multiple ventures: sales teams wasting capacity on wrong-fit accounts because targeting was guesswork, not systematic.
The problem we lived
If you've ever tried to systematically prioritize which accounts to target, you know the challenge. Standard filters give you thousands of companies: "B2B software, 50–200 employees, UK-based." Great. Which 200 of those 8,000 actually have your specific pain point? Which are in a buying window? Which will actually convert?
You try the "intelligent" tools. They promise AI-powered prospecting, intent signals, account scoring. What they actually deliver: surface-level firmographics that miss what really predicts conversion. You're back to reps picking accounts by gut feel.
We lived this across multiple businesses — as founders, as GTM leaders, as consultants. Every time we needed to systematically target accounts, we hit the same wall: no way to identify which companies truly fit without manual research that doesn't scale. No way to move from "looks like a good fit" to "scientifically ranked by conversion likelihood."
That's not a tooling gap. That's a foundational problem. And we decided to fix it.
Who's behind this
Dave Curran
Ex-BCG, 2x founder (exit to Glassdoor), former VP Product. Led product, sales, marketing, finance across ventures. 15 years solving GTM challenges — the hardest part is always linking product value to customer ICP. Every company guesses at targeting. Built Firmbase to make it systematic.
Alexander Dür
Co-founded PAXLY as CTO, raised €1M+. ML engineer who built optimization systems processing billions of events. Created algorithms identifying best-fit customers for suppliers — the targeting problem every B2B company faces. Combines data infrastructure with product sense to predict conversion.
What we believe
Targeting shouldn't be an art. It should be science. The best salespeople have pattern recognition — they "know a good fit when they see one." But that knowledge stays in their heads. New reps don't have it. The approach doesn't scale.
We believe every company should be able to systematically identify which accounts to prioritize, based on what actually predicts conversion for their specific product. Not generic filters. Not gut feel. Data-driven prioritization that gets better over time.
That's what we built.
If this problem sounds familiar — if you've felt the frustration of sales teams wasting capacity on wrong-fit accounts while high-value opportunities slip through — you're probably who Firmbase is for. We're always happy to talk. No pitch required.
