TAM list builder for AI agents
Build and enrich your total addressable market from Claude Code, Codex, or any MCP agent, described in plain language.
you › Build my TAM: US-incorporated B2B SaaS, $1M to $20M ARR, 20 to 200 employees. Add 3 GTM leaders per account and a verified email for each.
oxygen › Oxygen sources the accounts, finds the roles, waterfalls emails, and writes a deduplicated, enriched TAM table you own.
A TAM list is a company-first problem: define the universe of accounts that could ever buy, then find the people in them. Oxygen builds that universe from firmographic criteria and fills it out with contacts, all driven by your agent.
Describe the market, and Oxygen sources matching accounts across providers, finds the personas you care about, enriches contact data, and qualifies with AI, so the list you get back is one you can act on, not just count.

Frequently asked questions
Which agents can build a TAM list?
Any MCP client, including Claude Code and Codex. Oxygen exposes sourcing, enrichment, and qualification as tools, so the agent runs the whole build and you approve the spend.
How big can the list be?
Large builds run as durable background jobs with spend caps and observable runs, so thousands of accounts and contacts complete reliably rather than timing out.
Can I keep the list fresh?
Yes. Turn the build into a scheduled workflow so new matching accounts flow in over time, on a database you own.
