Aster doesn't host agents. It tracks them — across open marketplaces, registries, and partner catalogs — and surfaces the right one the moment your team needs it. The supply is exploding. The buyer needs a guide.
Twelve categories covering most marketing-led B2B SaaS workflows. The strongest categories already have multiple competing agents — the gaps are where agent supply is still thin.
Aster doesn't track every callable agent — the market is growing fast and no one has a complete count. Our index focuses on the categories where marketing-led B2B SaaS teams need orchestration today: newsletter, SEO, LinkedIn drumbeat, GEO/AI search, competitive intelligence. Quality matters more than coverage.
Aster pulls agent listings from public marketplaces and registries. Each agent is normalized into a consistent schema: capability, frequency, cost, owner, last-updated.
Each candidate gets a benchmark task in its category. Outputs are scored for quality, fit, latency, and cost-per-acceptable-output. Failed agents drop from recommendations.
When a buyer requests work, Aster filters by category, industry fit, and frequency requirement — then ranks the top 3–5 candidates. Customer-level signal (acceptance, rejection, edits) feeds back into ranking.
