Tessl
London
Tessl is an early-stage London startup building an 'agent enablement' / context layer for AI coding agents — a registry and governance layer where teams build, test, secure and version the skills their coding agents (Claude Code, Cursor, Copilot, Gemini) use. It was founded by Guy Podjarny, who previously founded and scaled the security company Snyk, and is backed by Index Ventures, GV, boldstart and Accel. Expect a fast, opinionated, in-person-leaning culture: its stated principles are 'Embrace the Pace', 'Build then Break', 'Grab a Shovel', 'Be AI Native' and 'Own It', and it mandates three anchor office days a week. As a young, venture-backed company its benefits are lean-but-solid (25 days holiday, options, private health, L&D budget) rather than big-tech lavish.

the legal floor where they are
Set by law, not by Tessl. It applies to every employer in London.
| Birthing-parent leave | 52 (Working Time Regulations 1998; Employment Rights Act 1996) |
|---|---|
| Partner leave | 2 (Working Time Regulations 1998; Employment Rights Act 1996) |
| State pension | auto-enrolment: employer contributes at least 3% of qualifying earnings (Working Time Regulations 1998; Employment Rights Act 1996) |
| Disability rights at work | Equality Act 2010: disability is a protected characteristic and s.20 imposes a duty to make reasonable adjustments (Working Time Regulations 1998; Employment Rights Act 1996) |
| Neurodivergent adjustments | Reasonable adjustments are owed on the IMPACT of a condition, not on a diagnosis. ACAS is explicit that no formal diagnosis is required, so the duty can arise before anyone has been assessed -- which matters when an adult autism assessment is a multi-year wait. Autism, ADHD, dyslexia, dyspraxia and dyscalculia are covered where the effect on day-to-day activities is substantial and long-term. Asking for an adjustment is itself protected: you cannot lawfully be dismissed or treated worse for asking. (Working Time Regulations 1998; Employment Rights Act 1996) |
| State school fees | state schools free; independent schools are unsubsidised (Working Time Regulations 1998; Employment Rights Act 1996) |
