## About

Based in London, UK, and founded in 2024 by founder and CEO Guy Podjarny, Tessl AI Limited is a software development company that leverages artificial intelligence to provide an AI-native development platform that enables users to create auto-maintained code by defining specifications, which are then used by its AI platform to generate and sustain software. 

Tessl specializes in an AI-native development platform that revolutionizes the software development process through spec-driven development. The platform allows users to define specific requirements, which the AI then translates into secure, and auto-maintained code. This innovative approach is designed to cater to various end-user needs, enabling developers and organizations to create complex systems from small, modular code units. Tessl’s offerings are tailored for a wide range of industries, with a client base that includes technology firms, startups, and enterprises looking to streamline their development processes. In March 2026, Tessl AI Limited raised USD 5 million in seed funding co-led by new investors Hi Ventures and DYDX Capital, with participation from another new investor Honeystone Ventures. 
The company will use the March 2026 funding to support the development and expansion of its enterprise agent orchestration platform.

Tessl.io's revenue model is primarily based on subscription services, where clients pay for access to the AI development platform. Transactions typically occur through tiered subscription plans that cater to different user needs, ranging from small startups to large enterprises.
