Built Oscilar's Finance and AI Infrastructure From Scratch as a Team of One
Oscilar, founded by Confluent co-founder and former CTO Neha Narkhede alongside risk leaders from Facebook, Uber, and LinkedIn, builds AI decisioning for fraud, credit, and compliance at banks and fintechs. Hamacher joined as the company's sole finance hire and rebuilt the function from the ground up, automating collections and revenue recognition to cut accounts receivable by roughly 40% and compress the monthly close from twelve days to four.
He stood up Finance, Accounting, GTM Operations, HR, IT, and Legal infrastructure, and consolidated AP onto a single platform covering vendor payments, expenses, and travel.
For commissions, he built a custom tool that replaced third-party software across 60 reps, cutting monthly calculation time from two days to roughly three hours. He then shipped a full-stack AI pricing agent that generates quotes, manages approvals, and produces customer-facing commercial decks for sales to walk through with prospects. The result is a finance function built to scale the business, not just keep score.
Finance is one of the most under-leveraged growth levers a startup has.
The best finance leaders don't just keep the books. They extend runway,
structure capital that changes what a company can do next, and build the
systems that let it scale across borders.
Startup Finance 30 is the first list built to recognise that work.
Beginning in 2026 and continuing annually, we name 30 finance leaders at
venture-backed, globally ambitious startups. The operators shaping how the
next generation of companies grow.
