Our Track Record

Solid Ventures has been active since December 2005 as the successor of the 300M. NeSBIC Converging Technologies Funds, founded in 1997. In 2000, this fund was one of the first and largest dedicated European tech venture funds. 

Our trackrecord is built on more than 30 years of many successful investments and exits, with notable successes as KPN challengers Versatel (IPO NASDAQ / AEX July 1999) and Scarlet Telecom (sold to Belgacom February 2008) and Oxxio Alternative Energy Provider acquired by Centrica (LSE:CNA) in June 2005) as challenger of the energy incumbents Eneco, Essent and Nuon. However, in the hectic early telecom and internet bubble days, we had also quite some failures such as Holland's first web retailer  HotOrange, while we should have invested in CoolBlue,  European web retailer LetsBuyIt,  with an  IPO on the Neuer Markt Frankfurt in July 2000 and then failed and BaBYXL, Holland's first ADSL internet provider sold to publicly quoted Tiscali (now KPN Telecom) for 1 euro....


Other successful exits were ITMasters, a Belgian developer of systems management tools,  acquired by BMC Software for $42 million in cash (NYSE:BMC), DataCenterTechnologies, now PureDisk acquired by Symantec (NASDAQ: SYMC), Dedigate (AMEX:TWW), Immidio (now VMWare, acquired by Broadcom), Backup Agent (now Acronis).

More than 25 years of early stage tech venture capital investing and still every day we are learning from our mistakes and enjoying our successes!
