Probably a good small business. Probably not this brief.
The brief asked for $500k to $1M a year of profit, or $10M of value in 3 to 5 years, on $100k to $200k of capital, without anyone taking a full-time job. The founding team's own red-teamed model says the base case misses all three. Here is the case, with the numbers that argue against it.
Against the brief
Bear, base, bull
Every number here is an Assumption from model.json. Values use three bases: a financial buyer on ARR (the base view), a financial buyer on EBITDA (the floor) and a strategic buyer on ARR (the upside).
Profit by year
Distributable = 85% of positive fully loaded operating profit (the plan's convention). Deferred founder pay is a real liability: if repaid from Y5+ cash, early distributions go mostly to that.
Targets in this scenario
Probabilities on this page are subjective estimates by the plan's authors, given as ranges, based on reasoning rather than a cited base rate. They are not actuarial odds.
Subjective estimates, stated as ranges
$500k+/yr fully loaded profit by Y5, conditional on passing the 90-day tests. Before validation: roughly 2 to 8%.
Subjective estimate Basis: reasoning only. It needs every bull driver at once: 12% churn, about 150 new shops a year by Y5, and Office attach of 30%+. No cited base rate.
A $10M sale in 3 to 5 years, conditional on passing the 90-day tests.
Subjective estimate Basis: needs the bull case and a strategic buyer, realistically Trimble. The one niche comparable, a reported $6.5M AVEVA purchase of FabTrol in 2015 (per a competitor, not independently verified) [S5], points to a low ceiling.
Meeting the brief's "no full-time job" condition through Y3.
Judgment Basis: the funnel and onboarding hours in the model. The founders' 10 to 15 hours a week combined becomes realistic only from about Y4, after a paid GM.
$200k in four gates
Each tranche is released only when the gate before it passes. The bear case is not a five-year plan; it is a stop at G2 or G3.
| Gate | Cumulative spend | Must be true to proceed |
|---|---|---|
| G0 · Validation days 0 to 90 | ≤ $15k | Census size bands show ≥ ~700 structural establishments at 20 to 99 staff; ≥ half of 20 shops get machine-readable piece lists, or PDF-BOM import works on their files; ≥ 5 of 20 sign a refundable deposit or conditional order at ≥ $400/mo after a demo on their own files; dollar-quantified pain from ≥ 5 shops; real EZIIL quotes in hand. |
| G1 · Design-partner MVP months 3 to 6 | ≤ $60k | ≥ 3 pilots reach ≥ 50% ship scans by week 3; ≥ 3 real detailer bundles parse correctly, including one mid-job revision; measured AI cost per mill cert and PDF BOM; mill-cert field accuracy ≥ 95% on a check set; zero ship-morning failures without a working fallback. |
| G2 · Paid launch months 6 to 12 | ≤ $120k | 8+ paying shops at list price; monthly logo churn under 2%; onboarding ≤ 30 hours per shop; one founder full-time. |
| G3 · Scale hiring Y2 to Y3 | ≤ $200k, then self-funding | 35+ shops; net revenue retention ≥ 100%; first implementer covers onboarding without founders; Office attach ≥ 10%. |
The three cheapest tests, in order
- Census size-band check ($0, one afternoon). Stop if fewer than ~700 structural establishments have 20 to 99 employees.
- File-reality and EZIIL-quote test (~2 weeks, under $1k). 20 shops send files from their last 3 jobs; get 2 to 3 real EZIIL quotes.
- Deposit test (days 31 to 60, under $10k). At least 5 of 20 owners sign a refundable deposit or conditional order at $400+/mo.
Where we challenge the model
- The bull case runs out of money at $150k. Faster growth burns more cash: bull's low point from $150k with pay deferred is about -$49k. A bull outcome needs $200k or a revenue-based line.
- Deferred pay is not free money. About $825k accrued through Y5 sits ahead of owner distributions or comes off sale proceeds. Base Y5 distributable profit of ~$118k/yr would take about seven years to repay it.
- Market share is aggressive. If the narrow 700 to 1,200 band is right, the base case needs 17 to 30% of real structural buyers to try Heatmark within five years. Misc-metals and Canada aren't optional.
- Office attach of 30% by Y5 is untested and carries blended ARPA. At $600 blended, base Y5 ARR is ~$1.5M.
- Support at 9 hours per shop per year may be light for 5:30am ship mornings. If onboarding stays at 30+ hours, base Y5 loses another ~$60k to $80k.
Comparables, with caveats
SaaS Capital, Jan 2025
Predicted private SaaS multiples of 4.8x ARR for bootstrapped and 5.3x for equity-backed companies, from a public index median of 7.0x. Evidence [S20]
No ARR size range given. Applying it to a $1.7M ARR, founder-dependent, construction-cyclical tool is a stretch, so the plan uses 2 to 3.5x for its base.
Vertical-software acquirers
Said to pay roughly 1.5 to 3.5x ARR for niche SMB vertical software at this size, underwriting on EBITDA. Unverified
Brokered deals under ~$3M ARR are commonly priced on SDE/EBITDA. Not checked this session.
