LO Capital

Louis Duclert and Olivier van den Broek, the co-founders of LO Capital and digital marketing firm Effilab, make investment decisions jointly. They rely on their own operator networks rather than a formal investment committee. Charles Duclert and Gautier Delabrousse-Mayoux, co-founders of the affiliated real estate firm Iroko, influence property decisions but do not hold titled roles at LO Capital itself.

It operates as a private investment company that does not accept outside capital. The vehicle reinvests retained earnings from the founders' operating business Effilab, making it functionally similar to a single-family office, though the firm describes itself simply as an 'Investment Company.' No regulatory filings indicate registration as an asset manager marketing to third-party LPs.

Deal flow originates through the founders' Effilab network, which spans digital marketing and technology startups across Europe. The firm does not maintain a public deal-submission process or participate in syndicates led by external venture firms. Allocations target early-stage rounds, including seed and start-up, with no minimum or maximum check size disclosed.

Confirmed holdings include the Tour des Dames residential property in Paris and the Groslay Warehouse in Val-d'Oise. Industrial assets are grouped under the Lutetia Portfolio, while exposure to European mixed-use properties runs through the Iroko Zen Portfolio, which spans France, Spain, Germany, Ireland, and the Netherlands. A vehicle called Quantsquare Portfolio rounds out the real estate book.

Iroko is a separate real estate investment firm co-founded by Charles Duclert and Gautier Delabrousse-Mayoux. LO Capital co-invests alongside Iroko in the Iroko Zen Portfolio, which holds mixed-use assets across five European countries. The two entities share overlapping principals — Charles Duclert is listed as a business partner of LO Capital — but operate as distinct legal structures with separate investment mandates.

LO Capital deploys capital through direct deals in both real estate and venture. There is no public evidence of fund-of-fund commitments or LP stakes in third-party managed funds. The firm's investment activity reflects a concentrated, operator-led approach rather than portfolio diversification through external managers.

The capital originates from the founders' operating business, Effilab, a Paris-based digital marketing firm. Louis Duclert and Olivier van den Broek built Effilab prior to establishing LO Capital, and the investment company effectively reinvests the retained earnings of that enterprise. No external wealth source or family inheritance has been publicly disclosed.
