Venture Capital

Redalpine

Redalpine is a Zurich-based multi-stage venture capital firm founded in 2006 by Michael Sidler and Peter Niederhauser, and has grown into one of the most active Swiss VCs by number of early-stage checks across the DACH and wider European technology landscape. The firm invests from seed through Series B across digital health, fintech, deep tech, climate tech, and software, and is best known as an early backer of N26, Taxfix, Inkitt, 9fin, and Proxima Fusion.

Redalpine closed its sixth fund at EUR 300+ million in 2023 and has built one of the larger Swiss-based venture teams, typically writing checks between EUR 1-15 million into companies it then follows through multiple rounds. It is a reference fund for Swiss and DACH founders looking for a locally anchored lead investor with international reach.

DDD Invoices

Ljubljana, Slovenia · Startup

DDD Invoices is a Ljubljana-based API-first compliance platform that lets software vendors, ERPs, accounting tools, and marketplaces emit fully compliant e-invoices and fiscal reports across dozens of jurisdictions through a single integration. The product abstracts country-specific formats (Peppol BIS, FatturaPA, UBL, FacturX, SAF-T, FA_VAT and others), government clearance flows, digital signing requirements, and archival rules, so the customer team does not have to track the dozens of overlapping mandates that the EU's VAT in the Digital Age (ViDA) agenda is phasing in. The company's bet is that mandatory structured e-invoicing across the EU between 2026 and 2030 turns what used to be a back-office nice-to-have into a default requirement, and that most vertical SaaS builders would rather buy than build that compliance layer. It is one of the clearest examples of a Slovenian B2B SaaS built directly against upcoming European regulation.
