Ari Helgason

Yo, so let me tell you about Ari Helgason, dude’s a total beast in the startup and VC world. The guy’s like a Swiss Army knife of entrepreneurship and investing, and his story’s pretty damn inspiring.

First off, Ari went to LSE, got a First Class in International Relations, so the dude’s got brains and some serious global perspective. But what really kicks off his process is jumping into the startup scene. He’s been in the trenches with a bunch of companies, Slite, Cutover, Nexthink, ClauseMatch, Silverfin, and more. Basically, he’s seen what it takes to build stuff that actually works.

But here’s where it gets interesting. He’s a legit serial entrepreneur himself. Co-founded WOAH, a SaaS platform for apparel workflow management, which got acquired and turned into Uphance. So he’s not just about investing; he’s been in the game, building and selling. Then he jumped into Fabricly, a Y Combinator-backed ecommerce clothing marketplace, so he’s got that startup hustle on lock, plus some legit runway in fashion and luxury ecommerce in London and New York. No cap.

Fast forward, he gets into VC, first as a Senior Associate at Dawn Capital, focusing on SaaS and fintech startups, which are his jam. Then he moves to Index Ventures as a Principal, doing multi-stage international deals. The guy really knows how to spot winners early. And now he’s a partner at Transition, a VC firm 🧪 that’s all about climate tech, supporting founders from seed to Series A. Basically, he’s shifted his focus to the big impact areas, climate change and sustainability, because he’s all about backing the future.

What’s clear is that Ari’s not just about making a quick buck. He’s driven by a bigger purpose, supporting founders, scaling startups, and pushing innovation that actually matters. His experience shows he’s super hands-on, both building and investing. The fact that he’s been on boards, like Kría, an Icelandic VC fund, and tied to both Europe and the US, just proves he’s got a global outlook.

He’s fluent in Icelandic, based in London, and clearly connected across continents. That’s the kind of guy who understands different markets and cultures, a real deal when it comes to spotting global opportunities.

Bottom line: Ari’s a mix of entrepreneur, investor, and mentor. He’s crushed it in startups, backed some cool companies, and now he’s helping shape the future of climate tech. He’s the kind of person who’s been there, done that, and is still out here pushing boundaries. No bullshit, he’s a legit force to watch.
