About Flavien Kulawik
Flavien Kulawik is based in London. He is co-chairman and co-founder of KLB Group, which Crunchbase dates to 1995. His LinkedIn profile says he co-chairs B2B service companies that he cofounded or bought with Jean-Marc Le Breton. Crunchbase also lists him as co-chairman and owner of AT Language Solutions and co-founder of Envirya.
He studied at Ecole Centrale Paris, now part of CentraleSupelec. He has been a volunteer with Fondation CentraleSupélec since 2021, and his LinkedIn lists him as president of BLOOM, an ocean conservation non-profit, since 2009. A UK startup directory describes him as an angel investor with over 25 years of experience co-founding and acquiring B2B service companies.
Crunchbase counts 14 personal investments and Tracxn counts 6 companies, so the full portfolio is not clear from public data. The earliest dated deal found is Silex Cognitive Sourcing in June 2017, which Crunchbase lists with two other investors. Tracxn lists Biomemory (seed, November 2022), Scienta Lab (Series A, December 2023), Claimy (October 2025) and HrFlow.ai (April 2026).
He is usually a co-investor rather than a lead. Claimy's round included Julien Codorniou and Jean-Baptiste Hironde, and HrFlow.ai's 2026 round was led by 115K and EmergingTech Ventures.
HrFlow.ai is the AI deal on the Lounge deals desk, a $7M round in April 2026. Press coverage describes that round as a pre-Series A led by 115K and EmergingTech Ventures, with Kulawik named among existing investors. Inforcapital lists him among the investors in HrFlow.ai's earlier 2018 seed round.
HrFlow.ai is a Paris company founded in 2016 and led by Mouhidine Seiv. It sells an API-first platform that structures and orchestrates HR data for recruitment and skills matching. Data providers also tag Alice & Bob, Adionics and 73Strings in his portfolio, but dates and round details were not confirmed.
Data aggregators put his investments at pre-seed to Series A, mainly in France and the United Kingdom. Tracxn lists enterprise applications and health tech as leading sectors, and Shizune lists software, AI and healthcare. Shizune puts the rounds he joined at about $1.3M to $7M. That is round size, not his own cheque. He has made no public statement about check size or about what he looks for in a pitch.
