Built for a new era of employment law decisions
Leo is building a new kind of employment law intelligence for HR teams and managers — combining AI speed with experienced human legal judgment.
[01]DECISIONS
Where Leo makes the difference
Employment law in the UK is complex, constantly changing, and expensive to get wrong. For many businesses, legal guidance arrives too late — after the mistake, after the dispute, after the damage.
Leo was built to change that. We believe employment law intelligence should be available at the point of decision, not after the point of failure. And we believe the strongest outcomes come from combining AI intelligence with experienced human legal judgment.
[02]PEOPLE
Built by people who understand law, technology, and what is at stake
Des Lekerman — Co-Founder & CEO
Former CEO of Kocho, a Microsoft identity and cybersecurity partner, where he scaled a private equity–backed technology business through multiple stages of growth. Des brings over 20 years of enterprise go-to-market experience, commercial strategy expertise, and a deep understanding of how trust-layer technologies are built and adopted. At Leo, he leads commercial strategy, investor relations, and go-to-market architecture, ensuring the platform is positioned for scalable growth and enterprise adoption.
Thalis Vlachos — Co-Founder & Head of Legal
A leading employment law practitioner with nearly 20 years of experience advising CEOs and senior executives on complex employment matters.

[03]WHY NOW
Why Now
The 2026 Employment Rights Bill introduces the most significant changes to UK employment law in a generation — including day-one unfair dismissal rights. The rules for managing people from day one have materially changed. Most businesses are still running processes designed for a framework that no longer applies.
Leo is built for this moment — AI intelligence verified by experienced employment lawyers, ready when the law changes and your business needs to move fast.
