Transition

Transition launched in 2019 with David Helgason, who built game-engine giant Unity Technologies from a Copenhagen apartment into a public company, as its anchor. He structured the firm alongside his brother Ari Helgason as a generalist early-stage venture fund based in London. The thesis is straightforward: founders who have scaled a category-defining company have asymmetric insight into what the next generation of European startups needs to go global. The firm writes first checks from pre-seed through seed, typically ranging from $500,000 to $2 million, and reserves follow-on capital to support portfolio companies into later rounds. The mandate is opportunistic across sectors, reflecting Helgason's own broad technical interests. Publicly disclosed portfolio companies include climate-insights platform CarbonCloud, digital health startup Peppy Health, and collaborative design tool Modulz. Geographically, the firm invests primarily across Europe, with particular activity in the Nordics and the United Kingdom. Transition operates as a lean partnership built around the Helgason brothers. While the firm does not publicly disclose total committed capital or team size, it raised its second fund in 2022. The vehicle draws limited partners who are themselves experienced technology operators, reinforcing a network-driven sourcing model. No affiliated philanthropic foundation or separate real-asset arm is publicly associated with the firm. May 2022: Transition announced the close of its second fund to continue investing in early-stage European technology companies (per Sifted, May 2022). The structural differentiator is the founder-operating pedigree at the center of the firm. David Helgason spent more than a decade scaling Unity to a platform used by millions of developers before its 2020 IPO. Transition funnels that lived experience into a concentrated early-stage portfolio, offering portfolio companies direct access to a founder who navigated technical product-market fit, developer ecosystem dynamics, and eventual public-market scrutiny. That operational depth, paired with a generalist sector scope, distinguishes the firm from many European seed funds that are either sector-specialist or managed by career investors without an equivalent company-building track record.

Frequently asked questions

Who runs investment decisions at Transition?

Investment decisions are led by David Helgason, the co-founder of Unity Technologies, and his brother Ari Helgason. The two partners built the firm to leverage David's deep operating experience scaling a global technology platform. They run a concentrated decision-making process typical of a lean partnership structure.

How is Transition related to Unity Technologies?

Transition was co-founded by David Helgason, who previously founded and led Unity Technologies as CEO for over a decade. The venture firm is entirely separate from Unity as a corporate entity, but Helgason's reputation and network from building Unity define the fund's access to deal flow and its ability to advise portfolio companies on scaling technical products.

What investment stages does Transition target?

Transition focuses on the earliest stages of company formation. The firm typically writes initial checks at the pre-seed and seed stages, with the ability to follow on through Series A. This approach allows the partnership to enter at formation and maintain meaningful ownership as companies scale.

Which geographies does Transition invest in?

The firm invests across Europe with a primary emphasis on the United Kingdom and the Nordic region. David Helgason's Icelandic roots and long operating history in Copenhagen and London inform this geographic concentration, though the mandate allows for opportunistic investments elsewhere on the continent.

Does Transition participate in fund commitments or only direct deals?

Transition operates as a direct investment vehicle, not a fund-of-funds. The firm deploys capital as a lead or co-investor directly into startup equity rounds. There is no public record of the firm making commitments into other venture funds.
