About Daniel Gutenberg
Daniel Gutenberg founded Gutenberg Communication Systems AG in 1991 and was its Chairman and CEO. Telindus Group acquired it in 2000. He then became Telindus Country Manager for Switzerland, Austria and Hungary and sat on its executive board.
He joined Vi Partners in July 2003 as a Venture Partner focused on IT. Vi Partners says he has been an active business angel investing globally since the sale. He holds several board seats in public and private companies. He joined the board of Swiss Rockets, a biotech incubator and accelerator, and is a co-founder of the Crypto Finance Conference in St. Moritz. He is also a member of the Technion Board of Governors and of the BrainsToVentures investor circle. SECA named him business angel of the year in 2011.
PitchBook lists 125 investments, 46 portfolio companies and 77 exits for him as an angel. Crunchbase counts 18 investments, so the totals differ by source. Swiss Rockets and the Swisspreneur podcast both say he has invested in 12 unicorns. Crunchbase names Twill, SmallRivers and Crypto Finance Group among his notable exits. He is active in 2026, with PitchBook showing deals dated June to August 2026.
His most recent AI round on the Lounge deals desk is the NextBusiness Seed of $3M in June 2026. Crunchbase shows that round with BackBone Ventures and four other investors.
Earlier AI-related rounds include Unique AI (Seed, December 2021, where Crunchbase lists him as lead investor) and fonio.ai. Vestbee reported that fonio.ai, a Vienna-based AI customer communication platform, raised €3M from 13 European angels including him. His own investments page also lists AI21 Labs, DeepL, Clarity AI, JobHire.AI and Mentee Robotics, but the sources do not give dates for those.
Crunchbase shows him in pre-seed and seed rounds such as NOAT, BOND, Unique AI and NextBusiness. Tracxn also shows an earlier Series A, Liom in 2021. His portfolio spans enterprise software, consumer, biotech and health, robotics, fintech and crypto, with companies mainly in Switzerland and the United States. Tracxn lists him as based in Zurich. PitchBook marks him as actively seeking new investments. He has not published a check size, so none is given here.
