Why Kleep
Kleep builds the intelligence layer for fashion e-commerce: sizing, discovery and AI imagery that 300+ brands run in production, Givenchy, Lacoste and Victoria Beckham among them. Every product is proven in live A/B tests, not in decks.
We are a small, senior, international team with offices in Paris (9th arrondissement) and, since January 2026, New York. The company is led by its founders: Federico (CEO, previously in venture capital and private equity) and Théophile (CTO, an ENS and Mines Paris engineer who worked in trading and quantitative research at Morgan Stanley and BNP Paribas).
Ownership here is real: ideas are heard, feedback flows both ways, and impact is tangible from day one. We hold a high bar, celebrate together, weekly team drinks, monthly events, annual off-sites, and stay serious about the work, never about ourselves.
