Lean launch test for San Diego

A compact way to test demand without cutting required verification, safety, or delivery quality.

Minimum credible offer

One measurable marketing service for one client niche with a fixed scope, delivery cadence, and reporting format.

Part-time fit: Strong
A small roster can fit scheduled delivery blocks when client communication and campaign response expectations are controlled.
Solo-start fit: Strong
A founder can start solo with a narrow specialty, proof samples, clear deliverables, and careful client scope.
Ongoing cost signal: Low
Software subscriptions, portfolio development, client acquisition, and occasional contractor support are the main continuing costs.

Must be ready

  • Define the niche, deliverable, boundaries, contract, and claims
  • Prepare one proof sample and a reporting template
  • Confirm software access, data handling, pricing, payment, and approval workflow

Can usually wait

  • A broad service menu
