About Kruncher

Kruncher is the AI intelligence platform for private markets, used by 100+ investment firms globally. Our AI agents ingest pitch decks, financials, news, and transcripts, turning it all into structured, actionable intelligence — not replacing analysts, but amplifying what they can do. We help VC and PE firms automate deal flow, due diligence, and portfolio monitoring so they can focus on what matters: making better investment decisions.

Investment decisions in private markets have historically depended on who you know, not what the data says. A fund with a 50-person analyst team will always see more and dig deeper than a lean emerging manager running on spreadsheets. Kruncher levels that playing field. A small team can now operate with the same data depth as the biggest firms, so capital flows to the best companies, not just the best-connected ones. We are growing fast with a team across Singapore, Europe, and the US.

The role

We're hiring a Full Stack Engineer to build and evolve our data-rich SaaS platform. You'll own features end-to-end: translating Figma designs into production UI, building complex dashboards and data visualizations, and developing the Node.js APIs and third-party integrations that power the product.

This is a high-ownership role on a small engineering team. You'll work directly with the CTO and product, ship fast, and take real responsibility for the systems you build — including documentation and runbooks.
