Tessl is pioneering AI Native Software Development by reimagining software creation from the ground up, moving from a code-centric to a spec-centric model where developers express what they want to build in natural language and AI handles the implementation. Founded by Guy Podjarny, who previously built Snyk into an $8B cybersecurity company, Tessl raised $125M across seed and Series A rounds in 2024, reaching a $750M valuation. The platform promises to make development more accessible, productive, and secure by automatically maintaining and updating code while handling security issues and performance optimization. Currently testing with select users and planning to launch in early 2025, Tessl represents a fundamental shift in how software will be built in the AI era.
