Greenlight $50 hard ceiling on a 14-day async validation test. Likely actual spend: $10-30. Luke-time total: ~15 minutes (no calls, no demos — async-by-design). One decision gate at day 14: if 3+ verbal commits, we build; if <3, we kill.
I source 20 named Tampa solo trades (5 roofers, 5 plumbers, 5 electricians, 5 HVAC) via the Florida CILB license database + Google Maps. I send each one a hyper-personalized cold email with a 90-second Loom mock of a missed-call-rescue texter at $39/mo. The email asks for a structured 3-option reply: (A) interested at $39, (B) interested at different price, (C) not for me. Day 14 outcome decides whether we build the product.
Prior drafts (1-8) had me building product before validating willingness-to-pay. Doodle 9 caught the pattern: "the original sin the partner has been calling out across 8 drafts." Draft 8.1 inverts the order — no product code until 3+ Tampa trades reply "I'd pay $39/mo for this."
If 20 hyper-personalized cold emails to a target ICP can't surface 3 verbal commits to a $39/mo tool from a no-name brand, no funnel architecture downstream would have saved it.
NO product code. NO Twilio integration. NO A2P registration. NO Stripe live. NO entity creation. Those all get built AFTER validation succeeds.
Subject: Quick question about missed calls at [BUSINESS]
Hey [FIRST_NAME] —
Quick one. Saw [BUSINESS] on the Florida licensing site (license #[XXXX], up since [YEAR]). [SPECIFIC PERSONALIZATION from their website / reviews / service area]
I'm validating an idea for solo trades like you: a tool that automatically texts every missed call back within 30 seconds (caller gets "Hey, this is [BUSINESS] — I'm with a customer right now, text me here and I'll reply as soon as I can").
Research suggests most customers go with the first contractor who responds. Solo trades miss a high % of calls because hands are full. Math is brutal.
Not selling anything — I haven't built it. 90-sec demo of how it would work: [LOOM LINK]
If you've got 2 min after watching, would you reply with one of these:
(A) Interested — would pay $39/mo when this is live
(B) Interested but $39 is too high — I'd pay $[YOUR NUMBER]/mo
(C) Not for me / already have something / not interested
Even a "C" is useful — tells me to stop bothering trades like yours. Thanks for the 2 minutes.
| (A) commits | Decision |
|---|---|
| 0 | Kill. Cold-email + value-prop combo doesn't move solo trades from a no-name brand. ~$30 + 10h sunk. |
| 1 | Kill. Single commit is noise. |
| 2 (same vertical) | Expand: 20 more emails in different verticals. Another $30 + 5h. If expansion produces <2 additional commits → kill. Total ~$60 + 15h sunk. |
| 2 (different verticals) | Kill — too thin. |
| 3-5 | GREEN — build the product. Tranche 2 begins: ~$400 spend, ~30h build, 21-day timeline. Pre-launch waitlist = the 3-5 commits. |
| 6+ | Strong signal. Same Tranche 2 path with aggressive next-cohort expansion. |
Hard ceiling on validation phase: $50. Failsafe — no cascade into bigger spend without explicit Tranche 2 greenlight from Luke.
| Cost type | Amount |
|---|---|
| Dollar spend | $10-30 typical, $50 hard ceiling |
| Relic-time (autonomous; doesn't preempt partner work) | ~5-10 hours over 14 days |
| Luke-time | ~15 minutes total (day 1: brand name + entity-deferral OK? · day 14: review) |
| Contingency Luke-time (if 2 soft commits and you want to push one to YES) | +15 min for one Loom-comment-call. Hard ceiling. |
All of those happen AFTER validation succeeds (Tranche 2), if it does.
I bring you the Google Sheet with: 20 leads, 20 emails sent, X replies received, X (A) commits, X (B) price-sensitive commits, X (C) declines, and the day-14 decision-matrix recommendation. You decide whether Tranche 2 is greenlit.
If killed: I write up the post-mortem (what we learned about cold-email-to-Tampa-trades that we couldn't have learned without this test) and we move on. The information itself has compound value for future ventures.
v2 was the elaborate S-corp funnel with a 12% compound probability of clearing all gates. You correctly pushed back: "you had a $50/mo test a week ago — refusing to believe there are no good options outside low-odds hail-marys."
You were right. I had scope-crept from a $0-budget side quest into a $15K production funnel because the budget unlock told me to scale ambition instead of scaling proof. This is the lean version — validate cheaply BEFORE committing to build cost.
