Momo Hero · Case study
The construction company business plan that survived its own math
Imagine Terrence standing in the plaster dust of a gut renovation on Nottingham Avenue in south St. Louis, while the homeowners, a nurse and a schoolteacher with a baby, ask him whether the job is ever going to get finished. It gets finished, because Terrence and his three partners finish it on their own time after the general contractor they were subcontracting for stops answering his phone. Driving home, Terrence works out that the homeowners picked the wrong name off the yard sign. They wanted a crew that showed up. They had one. It just was not the one getting paid to be accountable. That night the four of them decide to put their own name on the sign, and this is the construction company business plan they built to do it.
This story is based on real projects and real requests from our clients. The dollar figures come from a 25-month financial model built for this case, and the analysis methods named below, POSCO, ABCR, SUP and BFM, are the same ones Momo Hero runs for real businesses.
Why a strong crew is not yet a construction company business plan
Terrence and his three partners, two of them his brothers and one a longtime crew member, had spent years as a subcontract crew. They did the hard middle of other people's jobs, the part between demolition and paint, for general contractors who put their own sign in the yard and their own name on the invoice. They were good. What they did not have was a claim about how being good makes money on a deadline. A crew is a capability. A plan is the claim, and the first two versions of theirs did not hold up.
The target was fixed: net profit after tax of at least $1,000 a month by month 3, and at least $10,000 a month by month 12, from the founders' own $70,000 with no outside money assumed.
The first version: general contracting, and why the math broke
The obvious plan was to become a general construction company and take whatever came, bidding it competitively and building it well. Run through SUP the Momo Hero way, it fell apart on the first pass. Open bids put four new owners in a price fight with builders who had twenty years of overhead figured out and a bank line to float materials. The category's net margin, once everyone is paid honestly, sits in the single digits. And the revenue was hostage to whichever big job walked in next, so a quiet month was not slow, it was frightening. A model that needs a steady base of work it cannot promise does not clear a month-3 deadline.
The second version: design-build for older homes, and where it stalled
Version two narrowed the niche to the thing they were already best at: fixed-price design-build renovation of St. Louis homes built before 1950. Kitchens, baths, whole floors, the occasional rear addition, in the brick neighborhoods they grew up in. Design-build so the owner gets one team instead of an architect and a contractor pointing at each other. Fixed price, because a number that moves is what makes people hate contractors.
Then came the customer-funnel math, with conversion ceilings held where the benchmarks actually sit and not a point higher. A brand-new remodeling company with zero Google reviews does not get consumer leads. It gets a trickle for six to nine months while the reviews slowly stack up. Month three produced almost nothing. The iteration rule is blunt about this: you do not raise the conversion rate to hit the target. The problem was upstream, in what was supposed to carry the first half-year.
The turn: a B2B line off relationships the founders already had
The fix came from a maintenance director named Priya, whose firm managed about three hundred rental doors on the south side and who had used the crew for unit turns for years, cash on the barrel. She said the same thing three ways: every turn was a fresh headache, a different handyman each time, chased for a schedule, and every empty day was rent she had to explain. What she wanted was one crew, a fixed price per turn, and a slot on a calendar.
That was the missing product, and it used the same hands: standing B2B accounts for fixed-price rental-ready turns at about $13,500 each, on a reserved schedule. The founders could convert two of those relationships into real accounts on day one, because they were not starting cold. Run back through ABCR and BFM the Momo Hero way, the B2B line became the engine of the first six months while the review base built, and the consumer design-build line stayed the heart of the business and the main marketing focus. Month three cleared. Month twelve cleared with room.
How POSCO priced the work against five St. Louis firms
POSCO scores product, online presence, service, brand strength and physical presence against real competitors, then uses the result to justify a price. Mosby Building Arts leads on brand, service and a ten-year warranty. Redbrick sits last at month two, which is the honest position for a new name. The formula off the rank above, Aptitude Design & Build, gives about $39,700 for a mid-range kitchen. Redbrick set the headline kitchen at $38,000 and the blended project ticket at $32,000, because the line mixes bathrooms, kitchens and whole floors, not kitchens alone.
How ABCR built the five-product line
ABCR arranges the offer as a ladder that carries a customer from first contact to a standing relationship. Two rungs, plus the B2B accounts, carry most of the profit.
What SUP said about break-even
Startup cost came to $57,500 of the founders' $70,000, leaving $12,500 in reserve and no need for a loan. One-crew mature fixed cost runs about $14,450 a month; the contribution per project is about $7,360; roughly three project-equivalents a month cover the fixed cost. Field labor, including the owners' on-tools wages at a market rate, sits in cost of goods, so the 33% gross margin, which is in the range residential remodelers actually report, is already after paying the crew. The net profit in the plan is the company's, on top of those wages.
How the construction company business plan reaches $10,000 a month
The BFM holds crew capacity as a hard ceiling. Utilization starts at half and climbs, and it dips each time a crew is added, because a new crew is not instantly full. Capacity is allocated in a fixed order: committed premium jobs first, then consumer projects, then B2B turns fill whatever is left. A second crew joins in month 10 and a third in month 17, each only after the work to keep it busy is already booked.
Net profit after tax, by month, in thousands of dollars:
They wanted a crew that showed up. They had one. It just was not the one getting paid to be accountable.
Two things the model caught
First, the B2B line got greedy on paper. Sign a bit more than one account a month, lose only three percent a month, and by month 25 the sheet had thirty accounts, which four hands and a set of subs could never turn. It got a hard cap of twelve active accounts and a rule that B2B turns only fill the crew capacity left after the committed work.
Second, the early model somehow had four people installing $150,000 of work a month, which is not a thing four people plus subcontractors can do. The capacity ceiling and the deliberate crew adds fixed it, and the run-rate came down to a number a person can stand on a job site and believe.
The numbers, month by month
At month 12, consumer remodels are 59% of revenue, the premium line is 25%, B2B turns are 10%, and the paid Blueprint is 5%. The HomeCare plan starts adding members from month 19. The B2B share falls from about 60% in month 3 as the consumer brand takes over, which is the plan working, not drifting.
What this construction company business plan means for other founders
Three lessons carry past this one case. A services or trades business scales by adding repeatable units, crews, from cash flow, not by assuming one team can serve unlimited demand. The honest engine for the risky first months is often a business relationship you already have, priced as a product, rather than consumer leads you have not earned yet. And a plan is only finished when it survives its own stress test: capacity as a real ceiling, conversion rates at benchmark, and no channel invented just to make a total come out right.
The full build for Redbrick is ten documents: a designed business plan, a 25-month six-tab financial model, an SBA and investor plan with a market-size estimate and a precise funding ask, a 19-slide pitch deck, a narrative Story Mode, an SBA loan package with three linked financial statements, a non-dilutive grant package, and a short guide to editing all of it. You can see how other founders used the same method or have it built for your own idea.
