About

What is RevenueBase

RevenueBase provides B2B data feeds and APIs that verify, enrich, and surface contact and company records at scale, with a 30-day refresh cycle on paid plans. It's built for RevOps teams, GTM engineers, and GTM leads at mid-market and enterprise companies who need clean, structured data flowing into their CRM or AI workflows rather than a point-and-click prospecting UI. The standout capability is semantic search for net-new company discovery — you can describe a target profile and surface companies that match, rather than filtering through static lists. Data feeds run on a flat annual subscription with unlimited seats and no per-record fees, while API calls are pay-per-outcome, meaning you're only charged when a result is returned. The honest limitation: RevenueBase is infrastructure first — teams expecting a self-serve prospecting interface or built-in sequencing will need to wire those layers themselves.

Our verdict

Vanderbuild take

RevenueBase sits squarely in the data infrastructure layer — it's the kind of tool RevOps and GTM engineers reach for when they need verified, enriched B2B data piped into their stack rather than a UI to click through. The agentic story is real but not turnkey: the API is pay-per-outcome and wrappable, and with MCP server support confirmed, you can slot it into an agent orchestration layer without much friction — though you're assembling that layer yourself. Budget tier 3 means this isn't a casual experiment — the free Community Edition lets you validate your data model, but the $499/month Basic plan is where you get full fields and refresh cycles, so plan for that spend before committing. The core limitation to flag: there's no built-in sequencing or outreach layer, so if your team needs data and activation in one tool, you'll be stitching RevenueBase to something else downstream.

The wedge

Agentic stack profile

MCP server

Yes

Live MCP server — agents can call this tool directly.

MCP gives an agent structured, typed access to the tool — fewer endpoint-mapping headaches and cleaner auth than wiring REST yourself.

API

REST

Programmatic access available.

REST API — straightforward to call from any agent or workflow tool. Rate limits and auth vary by plan.

Agentic readiness

Capable

Solid API access — wraps cleanly for agent use.

Solid REST or SDK access. No MCP server yet, but easy to wrap in custom agent tooling. Most modern SaaS tools land here.

Stack role

Data source · Enricher · Verifier

Where this tool slots into an agentic pipeline.

Plays the role of Data source + Enricher + Verifier in an agentic pipeline. Use it to source contacts, companies, and the raw inputs an agent needs to act; add firmographic, technographic, and signal data to a lead row on the fly.
