Tessl secures $125M for AI-powered code platform

Investors have valued Tessl at over $500 million, backing its AI coding solution.
Tessl, a London-based startup, has secured $125 million to develop AI tools for creating and maintaining software.

London-based startup Tessl has raised $125 million in funding, achieving a valuation exceeding $500 million. Led by founder and CEO Guy Podjarny, the company aims to address challenges in managing software created by both humans and AI. Podjarny, known for his work with Snyk and Akamai, brings deep industry expertise in software security and scalability to this new venture.

Tessl plans to launch its AI-driven platform early next year, designed to simplify code creation and maintenance. The system will enable developers and non-technical team members to provide specifications in natural language or code, with Tessl generating code to meet those requirements. This approach allows users to test and adjust code in a secure sandbox environment before it’s deployed, with the AI automatically identifying and fixing potential issues to keep software running smoothly.

The platform is envisioned as open and adaptable, intended to work alongside other AI coding assistants. This flexibility has attracted significant investor interest, with Index Ventures, Accel, GV, and Boldstart among the backers. Tessl will initially support Java, Javascript, and Python, with plans to expand to more languages over time.

The name ‘Tessl’ reflects its goal of creating a seamless ‘tessellation’ of code, preventing overlaps and inconsistencies that often arise in software development. By streamlining the code lifecycle, Tessl aims to alleviate the increasing complexity in software engineering, particularly as AI-generated code continues to proliferate.
