partners' note: let 'em jump
The three words have been rattling around my head.
It’s the opposite of the investor reflex. The instinct is to catch the founder, smooth the runway, take the risk off the table. But nobody learns to land by being held in the air. They learn by jumping, missing, adjusting, and hitting the ground on their own feet. The hard part of our job isn’t removing the fall. It’s making sure that when a founder finally jumps, the right people are standing on the other side.
I borrowed the line from Brandon Webb, former Navy SEAL, and a New York Times bestselling author, who spent an evening with us this month unpacking what resilience really costs.
Here is how our founders jumped this month, and where they landed.

Aireen beats a global player at its own game
Most diabetic retinopathy screening still waits on a specialist to read a scan. Aireen turned the retina into a biological map a machine can read, and this month it paid off the hard way: head to head against a major global incumbent, in direct competition, Aireen won a significant European milestone. More than 5,000 cases of diabetic retinopathy caught. Not a pilot metric, real people flagged early because the technology works at scale.
This is the thesis in one company. Deep technical work, built in our region, beating the people who were supposed to own the category. The science was always going to be the hard part. Distribution and trust are what turn it into a win, and that’s where the next year gets decided.

MCP Bridge was just voted Dev Tool of the Week on Dev Hunt. Now they’re shipping Synthetic Tool Generation on Product Hunt, turning hidden legacy protocols like mainframes and SCADA into callable tools for AI agents.
Bioo:
From a lab idea most people called crazy to operations across four continents. Bioo turns soil into energy – powering projects even at SpaceX's Starbase with their biological batteries – and is closing its latest round via SEGOFINANCE. CEO Pablo Vidarte also won the 2026 DUX Sustainability CEO Award.
GRAI:
TechCrunch covered the bet: AI shouldn’t replace artists, it should make music more social. GRAI is building the interactive layer that sits on top of the music you already love.
Most AI reads text. PangeAI reads the physical world. Hospodářské noviny profiled the founders on how they analyze the 99% of satellite data that goes untouched.
Partner Laurence Vardaxoglou presented at the EU Commission’s JRC in Brussels: a cross-platform method, tested on the Armenian elections, for measuring and countering disinformation with real accuracy rather than guesswork.
ValkaAI builds real-time AI avatars. The team ran its first New York event at Tech Week by a16z, showing founders and NYC investors what's under the hood, and took its European Startup Embassy partnership bi-coastal with a scaling panel featuring Mews founder Richard Valtr and Apify's Petros Hong. A major product release is coming later this year.

Deep tech doesn’t sell itself. You win by getting in front of the right people early, in a room technical enough to judge the work.
Pointee’s Business Breakfast: Pointee packed the house to demo Guardian Agents live, walking the room through how you catch, pinpoint, and roll back an infrastructure incident before it spreads.
AI Tinkerers, June edition: We hosted the AI builders again. A full house of live demos from people actually shipping AI products: PostHog, Productboard, Vrgineers, Panel Labs, and Epassi.
Brandon Webb x Single Digit: A sharp evening with eight-figure entrepreneur and former SEAL Brandon Webb, on what resilience actually looks like when you’re building under pressure. The room left with more than a war story.
