Female-founded legaltech startup Aavalynx lands £1.5M to eliminate costly legal disputes

Hanna Roos spent 17 years inside the legal machine, watching companies burn through hundreds of millions of dollars on cases that dragged on for years. That experience is now the foundation of Aavalynx, a startup she co-founded in 2023 with mathematician-turned-entrepreneur Lauri Hyry. The company just closed a £1.5 million pre-seed round led by Omega Ventures, with Two Ravens and a handful of angels — including senior law firm partners and a former Amazon Europe exec — joining in.

The numbers Roos is chasing are staggering. The global legal services market sits at $1.15 trillion, and roughly 30% of corporate legal spending goes straight to litigation. A 2026 Norton Rose Fulbright survey found more than 80% of companies faced at least one lawsuit last year, and nearly half expect that to get worse, not better. Disputes can stretch on so long that the accumulated risk from open cases sometimes outstrips a company's entire annual revenue. That's the mess Aavalynx wants to get ahead of.

Its product, called Sisu, gives legal and business leaders live forecasts of dispute exposure instead of making them wait on periodic updates from outside counsel. Companies juggling multiple cases can see their total financial exposure at a glance and decide — earlier, and with actual data — whether to settle, fight, or walk away. Roos calls the endgame plainly: death to disputes.

That framing sets Aavalynx apart from most of the legal AI crowd, which has been racing to make individual lawyers faster. Wordsmith pulled in $70 million to bring legal work in-house. Harvey is valued at $11 billion. Legora, backed by Nvidia and Atlassian, raised $600 million at a $5.6 billion valuation. All useful, Roos argues, but none of it questions why disputes drag on in the first place — a dynamic she partly blames on hourly billing structures that let law firm margins hit 80% while doing little to align incentives with clients trying to resolve things quickly.

Early numbers from Aavalynx claim clients save around 30 times their costs in damages, fees and interest, and up to 200 times when factoring in preserved business opportunities — though those figures come from the company itself, not an independent audit. Omega's Birgir Ragnarsson and Two Ravens' Isaac Kato both framed the bet as much about Roos's team of disputes lawyers and Nordic tech talent as the market opportunity. The startup hasn't disclosed headcount or total funding raised, and says it's being deliberately choosy about future investors — prioritizing enterprise connections over quick closes.
