Investment thesis
OPRTRS CLUB positions itself as a community of 170+ operators from leading technology companies who back founders from day zero. Rather than offering only advice, its operators act as co-founders, providing hands-on support across go-to-market, product, hiring, internationalisation, and fundraising. The firm invests €200k in the first round and emphasizes standing alongside founders through the hardest early-stage challenges, opening doors and helping fix problems as they arise.
