ONE IDEA / TWO INDEPENDENT CHECKS
Buildable does not mean worth building.
Follow one tutor-booking idea through the Vibe Engine first, then the Market Engine. The build score and opportunity evidence never collapse into one false verdict.

VIBE ENGINE / CAN I BUILD IT?
Buildable with a hard MVP line.
A narrow booking and deposit workflow for independent tutors, without the weight of a full tutoring marketplace.

BUILD PROFILE
Five pressures, scored separately.

What continues after the first version ships.
Builder fit69

DECISION COCKPIT
Build reality and market opportunity stay separate.
Confidence describes the evidence. It never boosts or reduces the score.
Build reality
72/100
Buildable with a hard MVP line · 2–7 weeks at your stated pace · $0–$65/mo
Market opportunity
Needs validation
No aggregate score until at least 60% of weighted evidence is available.
Opportunity locked
Opportunity stays unknown until a Market read has enough evidence.
Thresholds are hypotheses: Build 65, Opportunity 60. Confidence is separate from the score.
PROBLEM FRAME / HYPOTHESIS
Scheduling and payment software for tutors
Independent tutors lose time and revenue when booking, confirmation and deposit collection happen in separate workflows.

ANALYST READ / EVIDENCE-CONSTRAINED
Paid scheduling behavior exists, but tutor-specific demand and switching intent are still unproven.
Recommended move: Sell a concierge booking-and-deposit pilot to independent tutors before building a practice platform.
The pilot tests the proposed workflow and price while avoiding a broad feature bet.
Riskiest assumption · Tutors care enough about an integrated deposit flow to switch from generic scheduling tools.
