MoltSets is positioning itself as an unlimited contact-data API for GTM agents, covering people and company search, email and phone enrichment, and validation. Practitioner conversation frames it as part of a shift toward consolidated data access for agent-built prospecting workflows, alongside other enrichment and signal providers. The company’s launch messaging centers on a simple commercial model for contact data and direct use inside Clay and Claude Code. Its presence is early but distinct: a developer-facing data layer intended to make enrichment waterfalls and outbound audience building more programmable.

Business Profile
MoltSets launched in mid-2026 as the fourth startup built by Adam Robinson, following RB2B and Retention.com, and is funded out of the cash flow those two businesses generate rather than outside capital. The product remains in closed beta, priced as a flat-fee unlimited plan rather than the credit-based model that dominates the contact-data category. Robinson has framed the build as deliberately lean, running a small team, using AI agents to handle customer support, and documenting the build process publicly through his own channels. It remains an independent, self-funded venture with no disclosed headcount or outside funding to date.
Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
MoltSets ships a documented API alongside an MCP server, wiring its contact-data waterfall directly into Claude Code, Codex, and Clay rather than requiring a dashboard. It has published a growing library of pre-built Claude Skills, now numbering in the dozens, that let an agent search, enrich, and validate contacts in plain English. The build-out reads as agent-first from the start rather than an API retrofitted for agents afterward.
