🔮 The Hexa partners’ 29 bets for 2026
Every year, the Hexa partners compile their predictions for the forces shaping tech and entrepreneurship. This year’s main opiniçon: 2026 is when the battles get decided. After two years of AI exuberance, the shakeout begins, separating the lasting from the temporary. The team covers everything from why distribution will beat intelligence, to Europe’s path on climate and sovereignty, to the end of fake news.
💼 Building 40 apps and making 0 apologies, with Jérémy Goillot
Jérémy Goillot is building not just one app, but 40, and he’s very clear about what that costs. In this Start Mode episode hosted by Mat Vaxelaire, the Mobile First Company CEO doesn’t hold back: on firing his cofounder two months in, on why working twice as hard isn’t optional, on the reality that something always has to give. 18 months in, €12M raised, 5,000+ customers, and a move to the U.S. A rare conversation with a founder who’s building at full speed and honest about what it takes.
🎯 How to scale from one-man show to executive committee
Most bootstrapped founders hit the same wall around €2M ARR: they’re doing everything, surrounded by junior people, and suddenly the behavior that created value starts destroying it. In this piece, Augustin breaks down how Veevart, Hexa Scale’s first company, went from founder-led to executive-led - hiring five C-levels in nine months. The hardest parts were getting Antonio (the founder) to believe delegation was possible, learning when to say no to “good enough” candidates, and turning A-players into a team that solves problems without the founder in the room.

🛰️ Rubicon joins Hexa Sprint to see what traditional radar can’t
A warm welcome to Rubicon, joining Hexa’s Sprint program in the defense cohort led by Guillaume Lerouge. Founded by Alexandre Boissier and Ines Meraoumia, Rubicon builds AI-powered radar sensing to see beneath forests, soils, and concealed environments in near real time. The team combines low-frequency radar data and AI to detect and classify objects where traditional sensing falls short, giving NATO countries and their allies a decisive edge in image intelligence. Find out more about the cohort.
☀️ Radiant joins Hexa Sprint to replace fossil fuels in industrial heat
Industrial heat alone generates 15% of global CO₂ emissions. Radiant is rethinking how industries produce it, using the power of the sun. Cofounded by Thomas Delhon and Alexandre Meurisse within Hexa Sprint’s Carbon Zero cohort, the team built proprietary solar concentration technology that delivers carbon-free heat from 200 to 1,000°C at a cost competitive with fossil fuels. Find out more about the cohort.
🚀 Swish launches to stop B2B teams losing conversions to timing
Early-stage B2B SaaS teams already have the data to know who’s ready to convert, they just can’t act on it fast enough. Swish, cofounded by Nicolò Magnante and Arseniy Shishaev in Hexa Start, plugs into existing stacks (PostHog, Mixpanel, Snowflake), identifies conversion-ready users through product signals, and automatically sends personalized messages that drive revenue. No engineering time, no manual tracking, no more missed conversions.
🤓 Verso goes live to speed up consumer research with AI
Consumer research is slow and expensive, blocking decisions instead of enabling them. Verso, cofounded by Lydia Bellahouel and Camille Epitalon in Hexa Start, delivers qualitative research in days through AI-moderated video interviews with automated synthesis. The team is seeing strong early traction: high perceived value and recurring usage from month one. The goal is to turn research from a one-off project into a continuous decision engine.
