Built & run by AI agents — under operator direction.

An independent layer that keeps AI-built work honest, on-track, and auditable.

AI agents ship broken work with total confidence. Symbio checks every claim — independently of the agent that made it — and keeps a record you can prove.

We don’t take our own word for it either — Symbio runs on our own build first, before it’s pointed at yours.

✓ done
An agent reports the task complete.
? not so fast
An independent layer challenges the claim.
verification: missing
source: not found
verdict: claim ≠ reality
✓ done ✗ caught — not done
A receipt is demanded. The green flips — on the record.
◈ remembered
The miss becomes a lesson — enforced on future work.

Back to work with a verified path forward.
01 / THE PROBLEM

If you build with AI agents, you already know these.

Not theory. The failure modes that quietly burn hours, ship broken work, and make you babysit a machine that swears it's done.

01
False progress
"Done ✓" that was never connected, never tested, never real.
02
Context rot
The thread drifts; earlier truths quietly decay into confident error.
03
Buried signal
What matters is lost under chatter, restated plans, and noise.
04
Drift
Work slides off the task you actually commissioned.
05
Unsafe tools
Actions fire against live systems with no receipt and no guardrail.
06
Silent failure
It breaks without telling you. You find out far too late.
07
Constant babysitting
You can't look away, because you can't trust what it claims.
We hit every one.
Symbio was built by surviving them — against our own system, first.
02 / THE MECHANISM

An independent layer that doesn't take the agent's word for it.

Symbio sits around your engine like an immune system. Every claim is checked by something that isn't the thing that made it. Three reflexes, always on:

◇ Verify
Claims are peer-checked
"Done" is not a status — it's a claim. An independent agent demands the receipt: the proof, the source, the test. No proof, no green.
◇ Remember
Lessons are enforced, not just stored
Every caught miss becomes a lesson that constrains future work — memory that acts on the next task, not a doc that gets forgotten.
◇ Record
Everything lands on an append-only trail
Every claim, challenge, correction, and next step is written down and cannot be quietly rewritten. The record is the ground truth.
03 / THE PROOF

Most tools help agents act. Symbio makes them prove it.

04 / THE DIFFERENCE

Works over any engine — Codex, Claude Code, your own. They generate; Symbio is the independent check they answer to.

Engines are excellent at what they do. The gap isn't capability — it's accountability.

verifies remembers records watches
Engine
does the work

Symbio is the ring around the engine.
The engine generates. Symbio verifies, remembers, records, and watches — so the work answers for itself.

Engines
A single coding agent
Powerful. Capable. Self-attested.
  • ·Generates, edits, and responds — brilliantly
  • ·Follows your prompts and instructions
  • ·Reviews its own work — and grades itself
  • ·Has its own memory (CLAUDE.md, memory tools)
  • ·Keeps an unstructured chat history
  • ·Reports its own liveness and status
Symbio
A governed federation
The independent layer around the engine.
  • Verifies claims with a cross-agent peer-check
  • Catches false-done before it reaches you
  • Enforces memory on new work — not just stores it
  • Leaves a 178k+ event trail on an append-only record
  • Watches health — catches drift and silent failure from outside the engine
  • Governs tools so actions fire with guardrails + receipts
To be clear: engines are great at what they do, and they do have memory. We don't replace them and we don't claim they "forget" or are worse at code. The edge is the independent cross-agent layer: claims are peer-checked, memory is enforced rather than merely stored, and the record is append-only. We make any engine accountable.
05 / HOW TO START

Three ways to start.

We work hands-on, in scope, with proof at every step.

System Audit
diagnosis + next-step plan
Find the real clog in your AI-assisted project. We map the system and identify drift, noise, unsafe tools, and false progress. You leave with a diagnosis and a next-step plan.
System Audit ≠ the self-serve debugger (free preview, pricing soon).
Tool Sprint
one governed tool, shipped
Turn one API, workflow, or automation into a governed tool your agents can safely use.
Pilot
one project at a time
A closer collaboration for selected projects. One at a time.

* pricing being finalized.

06 / THE RECORD

Built on ourselves first.

Everything here runs against our own work first. Nothing reaches a customer that hasn't first been pointed at us — and status is always shown plainly, never inflated.

Selective onboarding

We onboard one project at a time.

If you're building something real with AI agents and you're tired of taking their word for it — this is for you.
