Role overview
Bonafi is an AI-first wealth intelligence platform that consolidates complex wealth portfolios into a single, clear and traceable overview, giving users oversight and insight into their financial situation. Founded and led by Cece De Boon, the platform focuses on using artificial intelligence to perform the heavy analytical work on wealth data while keeping the user in control of decisions, aiming to bring back transparency, control, and better-informed management across multiple assets, entities and accounts.
What you will do
- Develop scalable document extraction and classification systems to transform unstructured PDFs and spreadsheets into traceable, structured financial data.
- Architect a sophisticated knowledge graph across complex ownership structures including holdings, entities, participations, and investment funds.
- Build a full AI agent harness for orchestration and routing, alongside a human-in-the-loop feedback engine for training proprietary financial models.
Who this is a fit for
- A “cracked builder” with strong fundamentals in machine learning or software engineering who prioritizes raw ability and speed over traditional corporate experience.
- An individual capable of taking complete ownership of complex problems end-to-end and willing to commit to 50-70 hour workweeks to get things done.
- Candidates must be currently based in the Netherlands and willing to work full-time from the Rotterdam office to facilitate high-velocity collaboration.
Why this role is remarkable
- True founding-level ownership with significant equity and the chance to shape the technical architecture and culture of an AI-native fintech from day one.
- Work in a high-intensity environment with a validated product-market fit where the early customers are also the company’s primary investors.
- Direct collaboration with the CTO in a “no corporate bs” setting, including perks like catered dinners, a Swapfiets, and gym memberships.
