Investment thesis

Korpun Siemen invests in early-stage (seed) companies, writing initial checks of EUR 50,000-100,000 and following on in later rounds up to a total of EUR 200,000 per company. It draws on a group of 33 angel investors, growth-company entrepreneurs and investors who have made exits, offering sector expertise and board support. The same investors previously deployed over EUR 60 million into more than 70 later-stage companies via SijoittajaPRO Corporate Finance, and now extend to earlier stages. The firm collaborates closely with Mint Palvelut (formerly SijoittajaPRO Corporate Finance) on follow-on rounds and can act as a passive financial investor when strong lead investors are present.
