Cost classification

Break-even is reliable only when fixed burn is kept separate from revenue-linked spend. Here, Month 7 break-even depends on treating rent and insurance as fixed, while cloud processing, commissions, audits, and lead generation scale with revenue.

Expense	Cost	Break-Even Treatment	Common Mistake
Headquarters Rent	Fixed	Model at $12,000 per month from Month 1 through Month 60.	Scaling rent with revenue instead of treating it as base monthly burn.
Cybersecurity Insurance	Fixed	Model at $3,500 per month across the operating period.	Leaving it below the break-even line as an occasional compliance item.
Core AI Payroll	Semi-fixed	Step up by planned headcount, including Lead AI Engineers and Computer Vision Scientists.	Modeling every engineering dollar as variable when hiring moves in blocks.
Technical Support Engineer Payroll	Semi-fixed	Start in Month 13, then step with support headcount from 1.0 to 4.0 FTE.	Adding support from Month 1 before the model shows planned hiring.
Annual Marketing Budget	Semi-fixed	Use planned annual spend: $250,000 in the first year, rising to $1,100,000 in the fifth year.	Treating the full budget as purely variable CAC spend.
Cloud Computing and GPU Processing	Variable	Apply 8.0% of first-year revenue, declining to 6.0% by the fifth year.	Fixing cloud spend even though biometric processing load follows usage and sales.
Channel Partner Commissions	Variable	Apply 5.0% of revenue each year as sales volume grows.	Counting commissions as fixed payroll instead of revenue-linked selling expense.
Direct Marketing and Lead Generation	Variable	Apply 4.0% of first-year revenue, tapering to 2.5% by the fifth year.	Blending lead generation into fixed brand spend and hiding margin drag.

How does break-even shift from a lean launch to a full enterprise rollout?

Scenario table

Break-even gets easier as the mix moves from standard access to higher-priced enterprise contracts, because CM ratio rises from 80.0% to 85.5% and the fixed team load is spread over more revenue. Month 7 is the clean break-even signal, with a 23-month payback.

Scenario figures are planning assumptions, not guarantees.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$156.7k	$31.3k	$119.4k	80.0%	$5.9k	Thin cushion; one weak month can turn it negative.
Base Year 3 scale case	$604.8k	$105.8k	$247.0k	82.5%	$251.9k	Best signal; Month 7 break-even supports the payback path.
Full Year 5 enterprise rollout case	$1.47M	$213.4k	$372.3k	85.5%	$886.0k	Wide cushion, but support and audit load still matter.

What pushes this gait recognition plan past break-even?

Stress test

The plan stays tight: Year 1 break-even is about $1.493M on an 80% contribution margin, so slower enterprise sales, a bigger support load, or cloud and audit creep can erase the cushion and push Month 7 break-even out.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$1,493k	$74k cushion	Month 7 break-even still depends on steady sales.
Revenue shortfall	Trial-to-paid conversion slips, pulling annual revenue to $1,410k.	$1,493k	$66k gap	Weak conversion can erase the monthly operating cushion.
Fixed costs	Fixed costs rise 10% to $1,314k as support and overhead grow.	$1,642k	$75k gap	Support hiring before paid rollout pushes break-even higher.
Margin pressure	Contribution margin falls from 80% to 75% as cloud and audit spend rise.	$1,592k	$25k gap	Cloud usage above 80% or heavier audits leave less profit per sale.
Combined pressure	Revenue falls to $1,410k, fixed costs rise to $1,314k, and margin falls to 75%.	$1,752k	$256k gap	This mix can push break-even well past Month 7.

Should you sign the lease, servers, and hires before the gait system proves it can break even?

Founder checklist

Not yet. Lock in those costs only after the pipeline covers about $149K a month, cash stays above the $358K floor, and the first-year trial and margin assumptions hold.

1Break-Even Pipe$149K/mo

Build enough qualified pipeline to cover about $149K in monthly break-even revenue before you lock in big fixed costs.

2Lease Load$12K/mo

Sign the lease only if that $12K monthly rent and the $360K early capex load still fit the Month 7 cash low point.

3Margin Mix80% CM

Keep cloud, commissions, audits, and lead gen near 20% of revenue so the 80% contribution margin can cover payroll and rent.

4Team Ramp5 FTE

Keep the 5 FTE Year 1 team in place and delay the Month 13 support hire until recurring revenue can carry faster response times.

5Cash Floor$358K

Keep cash above the $358K low point through Month 7; if you dip below it, slow hiring or delay spend.

6Trial Funnel15% / 25%

Scale marketing only if 15% of prospects start a free trial and 25% convert to paid, with CAC staying at $2,500.
