About Nume & Scaleup Finance

Founded in 2021 by 6 serial entrepreneurs, we’ve managed to scale our unique CFO-as-a-Service (tech+service solution) to more than €5m ARR and raising Denmark’s biggest seed round in the process. Today we are 60 people spread across our offices in Copenhagen, London and remote.

We’ve spent the last four years working closely with hundreds of startups and scaleups as their trusted financial partner, delivering CFO-as-a-Service through our SaaS financial management platform and real CFOs. We’ve built deep expertise in what founders struggle with: not just understanding their numbers, but acting on them with clarity and confidence.

That journey led us to create Nume, the world’s first AI CFO. Nume is currently in private beta and we are gearing up for a major public launch in August that aims to set a new benchmark for AI product rollouts

Built on years of real-world financial experience, Nume combines advanced AI with financial intelligence to bring the power of a CFO to every founder’s fingertips. From our roots as a CFO-as-a-Service business to our transition into an AI-first company, our mission has stayed the same: to help founders and small companies never worry about finance again.

We’re backed by top-tier investors, featured on Sifted’s list of Europe’s fastest-growing startups , and scaling fast.

If you want to shape the future of financial decision-making, this is the place.
