Announcing Marathon Venture Capital Fund III 💥 Since 2007, we have been on a mission – to bring our founder community together, and help build world-class technology companies. We founded some of the original startups, nurtured a community around them, raised the first venture capital funds, and delivered the first successful exits. In 2017 we launched @marathon_vc to go even further beyond – and we have been humbled by what followed! We have been privileged to work from day one with exceptional founders, solving some of the hardest problems out there – with a resounding success. They went on to serve the most demanding customers on earth, employ thousands of super talented people, raise hundreds of millions in follow up capital and create a lasting impact on their markets and our community at large. As a matter of fact, they also helped us along the way to establish Marathon as a top tier performer in global venture based on realised returns... Today, we are excited to announce Marathon Venture Capital Fund III! We raised €75 million in an oversubscribed single closing, and we are grateful for the extended trust of our backers, including EIF and HDBI. We are now in turn making such an amount available to ambitious founders building the future – just like you. We love being the first money in and work on non-consensus opportunities; we hope our portfolio speaks for itself. We are typically leading seed rounds with €1-2m tickets for 15-20% of equity under standard, publicly available terms, also maintaining our pro-rata in follow up rounds. Plus, as our community has been taking us places – with half of our investments originating beyond Greece, typically across Europe – we really look forward to where it will take us next. We are equally excited to share that @alexalexakis is now a Partner at Marathon! Alex has been the voice of our community for the last five years, helping founders meticulously craft their vision, and earning his place as the go-to person for the next generation of entrepreneurs. We could not be happier for him and are eager to continue building Marathon together. For a team that started out of an unlikely place, the above are no small feat. More importantly, as the adoption of technology accelerates and experience across our community accumulates, our ambition is getting stronger – and we are just getting started! Now, let's get back to work – if you are building something great, drop us a line, we'd love to chat.

Qwen3 can tell harmful sentences from harmless ones. Qwen3-TTS, an open text-to-speech model, cannot. By the time it starts speaking, it does no better than a basic program that just counts words! New research by @verno_labs reports substantially deteriorating performance in model comprehension capabilities when speech enters the picture. This comes with profound implications for anyone deploying such AI voice models in production. Call centers, apps or customer service applications are recommended to act upon the above to keep their outputs safe – the model itself is not able to.

Marco Rubio wants the West to rediscover what made it great. But what truly distinguishes Western civilization is not its military power or national pride, as Rubio suggests, but its intellectual and political traditions. My take:

The bottleneck is sales cycles. Pace your company building around it, not VC money.
Yoni Rechtman in August, on why “a better model doesn’t buy you a faster customer." People are still dramatically underestimating the friction left in the diffusion cycle.

I’m not. Will use SpaceX cold gas thruster system with ultra high pressure air in a composite over-wrapped pressure vessel in place of the 2 rear seats.

TWENTY THOUSAND FLIGHT HOURS Name an electric helicopter drone vendor that has more. Correct, there’s none…
Five aircraft. Twelve years. One mission. Our commitment to unmanned helicopters began in 2014. Every model since has pushed the boundaries of performance and aerial operations. Today, backed by over 20,000 accumulated flight hours and real-world experience we are taking the next step. It is time for the Velos V4. Ready to redefine what’s possible. Coming soon. #VelosRotors #UnmannedAviation #UnmannedHelicopter #UAV #ComingSoon #VelosV4

The number of seed and early stage investments across Europe in Q3 2026 was 32% and 23% down respectively vs Q3 2025, as per Crunchbase data. The big rounds are making all the noise, but the market needs more well-funded startups across stages, not fewer ones.

FT: NVDIA in talks to acquire Reflection AI! The company was valued at $25 BILLION in its most recent round last March. This would be the largest acquisition of a tech startup with a Greek co-founder ever by a long distance. Go get ‘em @real_ioannis Antonoglou!

The market correction is here, sans $NVDA's ecosystem. One could argue the same for venture..
Just carnage out there... Since June 1: - 89% of stocks are down more than 10% - 54% more than 20% - 29% more than 30% - 7% more than 50% Source: Morgan Stanley

Drone manufacturing & navigation capabilities is the name of the game as we speak – anything less, and you’re acting suicidal..
Osiris versus GNSS, 30 km over snow. The ground below was fully covered and the satellite map was not. Osiris matched the two anyway and touched down less than 10 m from the GNSS position, with GNSS recording only as ground truth. Terrain in this video is masked for operational security.

"Venture capitalists are basically fishermen, Mr. Draper said, dropping in countless lines and never knowing when they might reel in a whopper." RIP to the 2nd gen of venture's sole family with four generations in the game. archive.ph/YRgDY
