Tessl

Tessl is building a platform for AI Native Software Development, in which artificial intelligence is a first-class participant in creating software. In its model, developers express intent and taste, while AI handles implementation details. The company's product, the Tessl AI Native Software Development Platform, is designed with AI built in rather than bolted on to existing workflows. Its technical focus spans AI-native software development, AI agents, developer tooling and software engineering automation.

The company operates in the software development and developer tools sector and is active in Barcelona and Majorca. It was founded by Guy Podjarny, who previously founded Snyk. Tessl is backed by investors including Index Ventures, GV, boldstart and Accel.

Tessl describes its approach to the field as community-led: it holds that shaping the future of software development is a collective activity rather than the work of a single company. Accordingly, it invests in the AI Native Developer community and states an interest in builders working with agents and in the growth of the profession. The company organises in-person team gatherings, including offsites in Barcelona and Majorca.
