About Ralph Müller

Background

Ralph Müller is a German angel investor based in Frankfurt. Crunchbase describes him as a former Deutsche Bank board member. Seatti, a startup he backed, lists him as a serial angel investor, founder and former Deutsche Bank and Postbank board member.

Press coverage of his recent deals uses the same description. EU-Startups and Tech in Berlin both call him a former Deutsche Bank board member in their LawX reports. Crunchbase also lists him as an advisor at Movacar.

His own site, a full career history and any public statements on how he selects startups were not found.

Angel investing track record

Public databases list only a handful of his investments, and they disagree on the count and the dates. Crunchbase shows pre-seed participation in DivTax and an exit via Monite. He also joined a pre-seed round in Seatti, a Munich startup that helps companies reduce office and administrative costs. Peak and the HPI Seed Fund took part in the same Seatti round.

These records may be incomplete, since angel investments are often not announced.

AI investments

His most recent public AI deal is LawX, a Berlin legal tech company. It closed a €7.5M seed round in May 2026, led by Motive Partners, with WENVEST Capital, xdeck and SIVentures also taking part. LawX builds an AI-powered operating system for law firms and notaries. Ralph Müller took part as an angel, alongside Flink founder Christoph Cordes.

Monite, which is in his Crunchbase record, sells embeddable AI-driven invoicing and bill pay for software platforms and fintechs.

Investment focus

Aggregators list his focus as fintech, payments, SaaS and software, with pre-seed and seed stages and a Germany focus. His LawX investment extends this to vertical AI software for a regulated market. The LawX investors cited the potential of AI vertical software in regulated markets, though that statement came from the round announcement and not from him personally.

No public check size or personal investment thesis was found.
