FRONTIER WORKFLOW / HUMAN IN LOOP

The work, step by step.

5 controlled stages
01 / VALIDATE

Turn conversations into falsifiable demand bets.

Interview evidence, buyer language, riskiest assumption, offer test, decision threshold, and next experiment.

Human gate

The founder speaks to buyers and distinguishes stated interest from paid behavior.

02 / SELL

Give every real opportunity a next action and owner.

Qualified contacts, researched outreach, stage criteria, follow-ups, objections, and a visible pipeline.

Human gate

Approve targeting and outbound messages; require evidence for each claimed relationship.

03 / BUILD

Ship the smallest commercial release on protected source.

Acceptance criteria, focused branch, passing checks, preview proof, deployment record, and rollback route.

Human gate

A named human reviews code, customer data boundaries, billing behavior, and production promotion.

04 / OPERATE

Route customer signals back into product and pipeline.

Support themes, lost-deal reasons, request links, account follow-ups, and the next prioritized product bet.

Human gate

Escalate uncertain or sensitive conversations to a person with full context.

05 / CONTROL

Close the operating loop with reviewable financial truth.

Categorized transactions, reconciled accounts, cash view, exceptions, invoices, and a monthly decision note.

Human gate

The founder or accountant approves exceptions, taxes, payroll, and cash commitments.
