Tessl has raised £100m in funding, including a £20m seed round in April led by boldstart and GV, and a £80m Series A led by Index and Accel. This funding supports Tessl's mission to establish AI Native Software Development, a spec-centric approach that redefines software creation by separating requirements ("what" the app does) from implementation ("how" it does it).
Tessl's AI-powered platform allows developers to specify software needs in natural language, enabling AI to autonomously handle implementation, testing, and ongoing maintenance. This paradigm eliminates the inefficiencies of code-centric development, reducing maintenance burdens and accelerating application development.
The funding will fuel the development of Tessl's open, composable platform, set to launch next year, which aims to transform software engineering workflows and empower developers to build adaptive, scalable applications. Tessl is inviting early adopters to join its waitlist and contribute to shaping this new era of software development.
