Dimension breakdown
Score · confidenceAgent Enablement Platform from Snyk founder Guy Podjarny -- a package manager for AI agent skills with versioned installs, eval-scored quality, and (as of March 2026) Snyk-powered security scoring on every public skill (scanning now blocks installs of critically-flagged versions). Registry indexes ~3,000 skills plus version-matched docs for 10,000+ OSS packages; the broader SKILL.md ecosystem grew ~450x in 14 weeks.
Named enterprise customers with attributed quotes (Cisco, HashiCorp/IBM, plus ElevenLabs/PubNub skills on the registry); measured agent-improvement outcomes (1.26x-3.3x; Cisco skill 1.79x). Team has grown to ~58-60 employees (+50% YoY), correcting the prior eval's '~21' undercount.
Competitive landscape intensified: Anthropic's official Claude Code marketplace ships built-in (versioning + quality/security standards but no built-in evals confirmed) and 8+ skills marketplaces now exist (incl. Vercel-backed Skills.sh, Agensi) -- but only Tessl combines package-manager discipline, automated evals/optimizer, and Snyk security scoring in one stack.
Gaps: no SOC 2 / ISO 27001, no Series B (~18 months since Series A), thin Product Hunt/G2 presence, no independent third-party benchmarks.

Status rationale
Tracked because material enterprise validation is present (Cisco, HashiCorp/IBM as named customers with attributed quotes; ElevenLabs/PubNub skills on the registry; measured 1.26x-3.3x agent-improvement outcomes; Snyk security partnership) AND the package-manager-for-skills category is being established with Tessl as one of the most credible players. Rating 51 -> 52 (Opus 4.8 re-baseline): viability ticks 13 -> 14 on corrected headcount evidence (~58-60 employees, +50% YoY, vs the prior '~21' undercount); other five dims unchanged.
However: (1) no SOC 2 / ISO 27001 certifications block higher-confidence enterprise positioning; (2) no independent third-party benchmarks or analyst coverage; (3) Series B not yet raised (~18 months since the $100M Series A, Nov 2024); (4) competitive intensification (Anthropic official Claude Code marketplace built-in, 8+ skills marketplaces incl. Vercel-backed Skills.sh) creates structural distribution risk; (5) thin Product Hunt / no G2 presence means mainstream community-adoption signal is still light.
Tracked at 52 is a high-confidence watch position: genuine momentum without status-change-grade evidence yet.
Movement triggers
Upgrade to Assessed if: SOC 2 Type 2 certification achieved AND independent third-party benchmark or analyst coverage emerges AND skills registry crosses 10,000+ with sustained growth AND Series B closed. Downgrade to Detected if: named enterprise customers churn publicly OR Anthropic ships native versioning+evals in official Claude Code marketplace (commoditizing Tessl's core differentiation) OR no Series B within 12 months AND headcount stagnates OR Snyk partnership ends.
Hold at Tracked if current trajectory continues (steady registry growth, expanding enterprise logo wall, ongoing product cadence).
