- En Carta Diagnostics
Participated · Equity · Jul 2026
Founded in 2022 by Guillaume Horreard and Margot Karlikow, En Carta Diagnostics is developing a rapid point-of-need molecular diagnostic platform in an affordable cassette format that the company says delivers laboratory-level PCR precision in about 30 minutes. The technology uses aptamers to bind targets with high affinity and specificity and is positioned to detect indications across genetic, pathogenic and veterinary applications. En Carta has achieved first-in-human use and is running two clinical trials for its flagship early Lyme disease test in Boston and Bialystok, and in January 2026 received FDA Breakthrough Device Designation. The company has a co-development and commercialisation agreement with AAZ totaling a €13 million commercial partnership to bring rapid molecular tests for chlamydia and gonorrhea to market with committed volumes over five years. En Carta plans to industrialise via a fabless model with Circum Medical for cost-efficient, high-volume manufacturing and to expand from Lyme detection into STI screening while pursuing regulatory approvals in Europe and the US.

- Five Lives
Participated · Series A · Apr 2026
Five Lives offers a suite of digital therapeutic products, including Five Lives Brain Health for prevention and Five Lives Care, launched in early 2026, as a therapeutic solution for mild cognitive impairment. The platforms deliver over 500 adapted physical activity videos, cognitive games, language exercises, and personalized lifestyle recommendations with real-time difficulty adjustment. A randomized clinical trial of 180 participants across seven hospitals in the UK and France showed statistically significant improvements in executive function and quality of life after three months of use. The Care app is priced at €30 per month and has received recommendations from neurologists and geriatricians at leading French and British institutions. The company is pursuing reimbursement via France's PECAN digital therapy program with a target of 2027 and plans to integrate AI to further personalize sessions. Early traction includes 200,000 cumulative downloads and 5,000 active patients on the therapeutic app within two months, and Five Lives projects revenues of €400,000 in 2025, €1 million in 2026, and €5–10 million in 2027 upon reimbursement.
- Getinside
Participated · Equity · Feb 2026
Getinside provides software that lets medium-sized online retailers sell advertising inventory—known as retail media—by pooling their audiences so they can attract larger advertisers. The platform incorporates AI to automate campaign set-up and management, enabling the company to scale to thousands of merchants and advertisers without proportionally increasing headcount. Getinside currently works with more than 250 e-commerce merchants and 300 active advertisers that have executed 950 campaigns. The company generated €1.6 million in revenue in 2025 and is targeting €3 million by 2026. To support this growth, management plans to double its eight-person team and expand its advertising formats to include email post-purchase placements, product sampling, and social-media publications. By giving advertisers an alternative to GAFAM channels and allowing regional retailers to monetize traffic, Getinside positions itself as a democratizer of retail media.
