[INTENT]ion by ANDsignals ANDsignals

Start with intent.
Finish with requirements
engineers can trust.

[INTENT]ion turns product intent into measurable, verifiable, design-ready requirements using engineering reasoning, gap detection, traceability, and human-governed AI.

Early access opens to a small cohort of engineering leaders. Investor enquiries welcome.
01 · The problem

Most engineering failures are not failures of build or budget.

They are failures of intent. Vague briefs. Hidden assumptions. Requirements that were never properly interrogated before they hit a backlog. Decisions made in hallways and lost by Friday.

By the time the bug shows up in production, the real defect is six months upstream, in a conversation that nobody wrote down.

Teams ship features faster than ever, and yet rework, scope drift, and architecture regret keep climbing. The bottleneck has moved. It now sits between the human's intent and the system's specification. That is the gap [INTENT]ion is built for.

  • Product intent is often too vague for engineering execution.
  • Requirements written without enough measurable detail.
  • Missing parameters create downstream design uncertainty.
  • Verification and evidence needs are discovered too late.
  • Cross-domain risks across hardware, software, RF, FPGA, power, EMI/EMC, and certification are easy to miss.
  • Teams rely too heavily on manual review and individual experience.
02 · The cost

Insufficient requirements are the most expensive engineering decision.

Poor requirements show up as rework cycles, schedule overruns, certification failures, and products that ship unable to be verified. By the time they show up on a budget line, the damage is already done.

In regulated and safety-critical programs the compounding effect is severe. A missed verification requirement at concept phase can invalidate an entire certification pathway, triggering re-design, re-test, and re-submission. The cost is not measured in sprints. It is measured in programs.

03 · How we fixed it

Six problems every engineering team knows. One system built to close them.

CAPABILITY · 01
⟶ INTENT

Briefs arrive vague. They leave precise.

Most requirements failures begin with an assumption nobody questioned. [INTENT]ion interrogates intent the way a senior architect would, surfacing conflicting goals and unstated constraints before they calcify into rework.

CAPABILITY · 02
⟶ REASONING

Decisions disappear. Now they don't.

Why was this requirement chosen? What was rejected, and why? Engineering decisions become explainable artefacts, not folklore passed between people who were in the room.

CAPABILITY · 03
⟶ DOMAINS

Cross-domain risks go unseen. Not any more.

In electronics for example, every domain (RF, PCB, FPGA, embedded software, power, EMI/EMC) has dependencies on every other. A change in one affects the rest. [INTENT]ion activates the relevant domains and reasons across their interactions.

CAPABILITY · 04
⟶ GAPS

Missing parameters hide until it's expensive. Not here.

Blind spots, weak assumptions, and incomplete requirement logic have a way of surfacing at the worst moment. [INTENT]ion finds them before they become design decisions you can't undo.

CAPABILITY · 05
⟶ TRACEABLE

Intent gets lost between the idea and the spec. Not with this.

Every link from intent to question, parameter to decision, requirement to verification is maintained. Nothing falls out of the chain between concept and delivery.

CAPABILITY · 06
⟶ GOVERNED

AI assists. Engineers still own them.

The system assists, but it does not approve. Every requirement passes through human review before it is promoted. Authority boundaries are explicit, auditable, and not negotiable.

04 · Auditability

You don't need to build for defence to need a decision trail.

Auditability is usually framed as a certification problem, something you care about when building for defence or medical programs. But the real cost of an unauditable requirement process shows up long before any regulator does.

It shows up when someone asks why a decision was made six months ago and nobody can answer. When a change request arrives and the team doesn't know what the original intent was. When a defect surfaces in production and the requirement that should have caught it turns out to have been written by someone who has since left.

An auditable process isn't about compliance. It's about not losing the reasoning that holds your product together.

[INTENT]ion maintains a complete, traceable record from the first statement of intent to the approved requirement: what was decided, what was considered, what was rejected, who approved it, and how it will be verified. Not assembled under pressure at the end. Built in from the first conversation.

If you are building for a regulated domain, that record becomes your certification evidence. If you are not, it becomes the institutional memory your team actually needs.

05 · Who it’s for

If any of these sound familiar, you’re the reason we built this.

  • You shipped something that didn’t match what was originally intended and nobody can explain why.
  • Something critical was missed late in the program that nobody caught earlier, and by the time it surfaced the cost was already compounding.
  • Your team spends more time in review, reporting, and tracing things than in forward progress, more time keeping track of what was decided and what will ship than actually building.
  • You’re heading into a certified program and you know the evidence trail isn’t there yet.
  • You’re not in a regulated domain, but you’ve lost institutional knowledge when people left, and with it, the reasoning behind decisions nobody wrote down.

If you recognised yourself in any of those. [INTENT]ion was built for you.
