Unless is led by CEO and co-founder Sander Nagtegaal, CTO and co-founder Marcel Panse, CXO Ecesu Erol, and CCO Martijn Groot. The team has shipped SaaS, AI, and component frameworks for more than a decade, with deep experience in regulated European markets. ### Who else is on the team? The wider team includes Alexandre Moreau-Lemay as Lead AI Engineer, Gray Lewis as Lead Fullstack Developer, and Antonin Remy as Senior Business Development Representative. Unless is small on purpose, and the team is built to do one thing and do it right. ### What experience does the team bring to regulated industries? The team has worked directly with banks, insurers, pension providers, HR and payroll platforms, healthcare organizations, and ERP vendors across Europe. That experience shapes how Unless treats privacy, governance, and integration. The agent ships with the controls those buyers ask about, not as an after-sales add-on. ### What is the Unless culture? Direct, technical, and useful. We are small and we like it that way. We choose to do one thing and do it right, apply Occam's Razor to every solution, and ship the smallest thing that helps. Novelty for its own sake is not a value here. ### How does the team work with customers? Like a partner, not a vendor. Product, success, and engineering specialists sit with customer stakeholders to design the use cases, configure the agent, and tune the loop. The four-week pilot is run jointly, so your team learns the platform while it watches the first numbers land. ### Is there an advisory board? Yes. The advisory board includes Sabine van Velsen (ex-Google sales leader), Christina Caljé (former Goldman Sachs Executive Director), and a group of seasoned tech investors. They guide us on strategy, governance, and go-to-market inside regulated markets, helping us balance innovation with risk and compliance. ![](/assets/einstein-hats-paper.svg) ## We're here to help Quick responses if you have an issue.
