Propel is the system of record for AI software delivery. The place where business, engineering and legal agree on what to build, deliver it with AI, and prove — continuously — that what shipped is what was agreed.
Every “just make it do X” still lands on your desk. The client thinks it's one more prompt. Nobody else remembers what was agreed. You do — because when it breaks, it's your name on it.
“The vibe-coding looks like magic — right up until it ships, breaks, and it's me and my team left holding it.”
Every change traces back to a decision, not a vibe. What hits your desk arrives with a record of how it got there — so fixing it isn't archaeology.
“Every change is just another prompt to them now. They've stopped believing software costs anything.”
There's a signed spec to point at. “New” means new — measured against what was actually agreed, not what anyone half-remembers.
“I'm done re-litigating the price every single time the scope quietly grows.”
Scope is tied to the estimate. When it moves, the number moves with it — on the record, before the work starts, not in an awkward email after.
“‘Who approved this?’ Nobody can say. There's no trail — so somehow it's on me.”
Every approval, change and sign-off is recorded and attributable. “Who approved this” always has an answer — and it stops defaulting to you.
For thirty years, software was the constraint — projects failed because teams couldn't build fast enough. AI removed that constraint. The hard part isn't writing code anymore.
Teams were bottlenecked on engineering capacity. The risk was shipping too little, too late — so the whole industry optimized for speed.
Anyone can now generate more software than they can align on, trace, or govern. The new risk is drift — building quickly in the wrong direction, with no record of who agreed to what.
Software isn’t built from code. It’s built from decisions.
Code changes by the hour. The decisions behind it are what must last — so Propel keeps them, as the record everyone builds from.
A solo agency and a regulated enterprise are doing the same thing — reaching, building and proving agreement. Pick where you live; the record underneath is the same.
Turn a rough brief into a priced, specified proposal in an afternoon — then bring the client into a shared deal room where approvals actually happen.
Replace the spreadsheet-and-deck handoff with a living agreement business and IT both sign — and a chain that links every requirement to what actually shipped.
Your policies are gates, not guidelines. Every build is checked against the stack you've approved and the compliance you owe — and the evidence is kept.
Builds aren't generated from scratch. They're assembled from a catalog of components your organization has already approved — so what ships is reliable by construction, faster to deliver, and cheaper to run.
Reach agreement, then build it your way: assemble it with Propel and ship through your own CI/CD, or send the spec and artifacts to your vibe-coding tool of choice and make it far more reliable. Both paths land at the same proof — what’s live still matches what was agreed.
A raw problem captured with its assumptions and constraints.
Team, effort and price take shape, sized against the scope.
A client-ready offer: scope, price, timeline, assumptions.
What the price buys, made explicit — the legitimacy behind the number.
Spec + estimate, signed — the shared source of truth everything traces back to.
Governed assembly from approved components.
Your own pipeline deploys what was assembled.
Carry the spec + artifacts into Cursor, v0 or Copilot — making those tools reliable.
Your own pipeline deploys what those tools produced.
Continuous evidence that what is live still matches what was agreed.
Eight surfaces over a single system of record, in three phases. Reach agreement, build from it, prove it stays true — pick where you work; the agreement underneath is the same.
Agree on what to build — idea, estimate, spec, signed deal.
Capture assumptions, risks and open questions before delivery starts.
Size the team, plan and price — an estimate you can defend, backed by a real spec.
The detailed, versioned spec that justifies the price and anchors every build decision.
Align clients, suppliers and internal teams around a single agreement.
Turn the signed agreement into working software.
Trace every line back to the agreement — who decided what, when and why.
Assemble from approved components — with Propel, or hand the spec to your own AI tools. Either way it traces back.
Prove it stays true — and evolve it from what ships.
Embed legal, compliance and organizational policy directly into delivery.
Watch what’s live, learn from real usage, and feed improvements back into the next agreement.
You don't buy governance. You buy a record every stakeholder reads from — so architecture, security, compliance, legal and risk all trust the same agreement. Traceability, policy and evidence fall out of that, automatically.
Audit-ready bundles generated from the trail itself — for security, compliance, legal and risk, without a fire drill.
Bring your own model keys on Delivery and Enterprise. Your code and context stay under your control, not ours.
Each approval, change and sign-off is recorded as an immutable, attributable decision — an audit trail legal and compliance can stand behind, not reconstruct after the fact.
Less ambiguity, less rework, less drift — and the runaway token cost that comes with them. When the model builds against an agreed specification, it builds the right thing once instead of three times. Predictable delivery, predictable bills.
Capabilities shown are illustrative of the Enterprise tier; specific certifications and figures available under NDA.
For delivery teams — what's at each stage and what's stuck. The Estimator lives in the early stages.
For everyone aligning — each engagement by the state of its agreement: proposed, agreed, drifted.
For enterprise — proof that what's live still matches what was agreed.
