Compliance work is too important for a black box.
Thirdsentry is the AI-native GRC and TPRM platform for the regulated mid-market — built by GRC operators, audit veterans, and AI engineers who've lived the work and refused to accept that every available platform either bolts AI onto a 2018 architecture or charges enterprise dollars for mid-market features.
One platform. One data model. One coherent risk story — defensible to anyone who asks.
Internal compliance posture and vendor risk posture are the same posture. Your auditor, your regulator, and your procurement counterparty all want one coherent risk story — not two disconnected workflows stitched together with weekly status meetings and an aging spreadsheet.
We built Thirdsentry because the existing options don't deliver that story. Compliance automation incumbents bolt vendor risk on top of a SOC 2 product. TPRM scoring vendors never connect external signal back to internal control records. Enterprise GRC suites solve it but require six-figure budgets and 6–12 month implementations the mid-market doesn't have.
So we built it differently. Internal posture and vendor posture on a single data model. AI as a colleague, not an autopilot. Audit-grade integrity in the data layer. Flat-fee unlimited-user pricing — because security teams shouldn't be punished for growing.

Where we are, plainly.
No fake traction stats. Here's the actual state of the company.
Where we were
The frustration
GRC Managers running multiple frameworks across spreadsheets. Vendor risk teams juggling Vanta or Drata for one slice and Bitsight for another. Effy-style AI helpers built on top of databases the vendor never owned. Renewal sticker shock every year.
Where we are
Building publicly
Live in production at customers across fintech, insurance, healthcare SaaS, and regulated B2B SaaS. Eleven frameworks pre-seeded. Twelve Effy specialist agents live. Posture Divergence Detection in production. Series Seed in motion.
Where we're going
The thesis
Internal compliance posture and vendor risk posture are the same posture. The auditor, the regulator, and the procurement counterparty want one coherent risk story — not two disconnected workflows. We're building the platform that delivers that — for the regulated mid-market that's been overcharged and under-served.
Built by people who've sat in the audit room.
Thirdsentry is built by GRC managers who've answered the 300-question security questionnaire under deadline, audit veterans who've defended evidence to an examiner, and AI engineers who treat the tenant boundary like a contract — not a configuration.
We've shipped compliance programs for the kind of regulated mid-market companies we now sell to. We know the rhythm of an audit cycle, the pressure of an enterprise security review, and the frustration of paying a renewal that doubled because your team grew.
Founder bios and named introductions land here as the team rounds out. In the meantime — if you want to know who you'd be working with, we'll happily get on a call.
"Most platforms in this space were built before AI mattered, and bolted it on after. We started the other way around — AI inside an audit-grade data model from day one. Then we made it cheap enough that mid-market teams don't have to choose between solving compliance and growing their team."
Six principles that shape the platform.
These aren't aspirational values on a wall. They're enforced in the code.
Humans approve every AI action
AI drafts. AI suggests. A reviewer signs off before anything publishes, scores, or ships back. Effy is a colleague — not an autopilot.
Every answer cites its source
When AI drafts a response, you see the policy, control, or evidence file it came from. No invented facts in front of an auditor.
Tenant isolation is architectural, not configurable
Org context is bound server-side before any tool runs. The LLM cannot see another customer's data — and cannot supply or override the org_id even if asked.
Workflows mirror real work, not vendor imagination
Audit cycles, vendor cycles, and questionnaire cycles flow the way they actually move in your team. You don't retrain your process to fit our software.
Defensible to your examiner, not just your auditor
AUDITOR role is read-only at the data layer. Immutable PolicyVersion on publish. AuditLog on every mutation. The integrity story is in the data layer.
Built openly, shipped openly
We share our roadmap, our positioning, and our tradeoffs publicly. The platform you see is the platform we run.
