Three products, each built for one kind of team and one job. All three are coming soon.

Line 01 · HubSpot app Coming soon

Champion Tracker

Know the moment your champions change jobs.

A champion who moves is often your warmest next deal. Champion Tracker watches the contacts you pick and tells you when one leaves, so you hear first and can act on it without polluting your CRM.

For B2B sales, customer success and RevOps teams on HubSpot.

Track only who mattersYou choose who to follow. Nothing is tracked by default.
Moves judged carefullyA confirmed departure alerts right away. An uncertain new employer goes to review, not a guess.
Alerts where you workSlack, email and a HubSpot task for the contact owner.
Your CRM stays cleanChanges show as a field-by-field preview. Nothing is written until someone approves it.

Property Data Router

Every property data source your agent needs, behind one key.

Property data is scattered across dozens of vendors and thousands of public portals. The router gives your agent one key, one prepaid balance and one connection, picks the right source for each request and hands back a receipt for every call.

For People who work parcel by parcel, in solar, insurance, lending, investing and the trades, and the developers who build their agents.

One key, one balanceNo juggling vendor accounts and invoices.
Built for agentsAsk for a kind of data. The router finds a source, and falls back if one fails.
A receipt for every callSource, units, cost and license terms, every time.
Spend controls, your keysBudgets per key and per person. Bring vendor accounts you already have.

Line 03 · MCP & REST Coming soon

OSINT Router

People and infrastructure intelligence for your agents, behind one key.

Investigators and security teams juggle keys for dozens of intelligence sources: people and identity lookups by email, username, phone or name, plus domain and WHOIS history, DNS, certificates, exposed infrastructure and IP and URL reputation. The OSINT Router puts them behind one key and one balance, and answers in a shape your agents can use directly.

For Investigators, due-diligence researchers, security analysts, threat-intel and SOC teams, penetration testers, and developers building investigation and security agents.

Agent-first outputsClean, consistent results instead of raw vendor responses.
Provenance on every resultWhich source answered, and when.
Price before, receipt afterPrepaid credit and no surprise overages.
Scoped keys, licensed sourcesBudgets and permissions per key. Bring your own keys for sources you already pay for.

How we build

One factory, one way of building.

Built with Claude

Every product on this page is designed and built with Claude, Anthropic's AI model, working alongside us from first spec to shipped code.

Narrow on purpose

Each product does one job for one kind of team, and does it properly.

Agent-ready from day one

MCP and REST surfaces with clean, consistent outputs that agents can reason over.

Nothing happens behind your back

Previews before changes, prices before calls, receipts after them.
