EDTECH: LEVERAGING AI-POWERED TECHNOLOGIES TO TRANSFORM THE LEARNING EXPERIENCE
1. Technology overview
Tessl AI Ltd is a company based at 210 Pentonville Road, London, backed by Index Ventures, GV, boldstart and Accel according to its About page. It builds an agent enablement platform described as the management layer between developers and the coding agents they use.
The platform provides a registry and control plane for agent skills and context, with evaluations that compare agent performance before and after context is applied, plus security scanning of skills. Loops run recurring agent tasks such as code review, skill optimisation, security scanning and documentation maintenance. It works with Claude Code, Cursor, Codex and Antigravity, and the site lists customers such as Cisco, Zillow, Intercom and JetBrains.
2. Highlighted features & specifications
- Tessl Registry: searchable index of skills across an organisation and private workspace.
- Context evaluations: before-and-after evals of agent context.
- Security scanning: checks skills against custom standards.
- Loops: recurring tasks such as code review, test-and-fix and incident post mortems.
- Bring your own model: switch models through configuration.
- Agent support: Claude Code, Cursor, Codex and Antigravity.
3. Potential application
A Vietnamese software exporter can share coding conventions across teams as agent skills. A bank IT department can scan agent skills for security issues before rollout. A platform team can benchmark agent cost and quality.
4. Benefits
- Central registry of agent skills lets organisations share and govern context across teams.
- Before-and-after evaluations show whether added context improves agent output.
- Security scanning checks skills against custom standards.
- Free tier with 1,000 credits per month lowers the cost of a pilot.
5. Market trends & opportunities
As organisations deploy several coding agents, managing shared context, skills and policy becomes a new platform need. Vietnamese enterprises standardising on AI coding tools will need ways to measure and govern agent behaviour.
