Which costs are fixed and which move with sales in this investment platform break-even model?
Cost classification
Your Month 18 break-even only holds if fixed burn and activity-driven spend are split cleanly. Keep the $69,000/month core overhead fixed, then let data, execution, marketing, and staffing scale as modeled.

Cost
Break-Even Treatment
Common Mistake
Cloud Hosting & Infrastructure
Fixed
Model as $25,000/month from Month 1 through Month 60.
Tying hosting to revenue and understating fixed burn.
Core Software Licenses
Fixed
Include $15,000/month in fixed overhead before contribution margin.
Moving licenses into variable fees to improve break-even.
Regulatory & Fixed Legal Retainer
Fixed
Carry $10,000/month separately from variable compliance fees.
Blending the retainer with usage-based compliance spend.
Market Data Feeds
Variable
Apply 3.5% of revenue in the first year, falling to 2.2% in the mature year.
Treating data feeds as flat while revenue scales.
Trade Execution & Payment Processing Fees
Variable
Apply 4.5% of revenue in the first year, falling to 3.2% in the mature year.
Ignoring fee drag in high-volume months.
Digital Marketing & Advertising
Variable
Model as 8.0% of revenue in the first year, declining to 5.0%.
Double-counting it with acquisition budgets.
Seller and Buyer Acquisition Budget
Semi-fixed
Budget $4.5 million in the first year, then step up by plan.
Treating acquisition spend as flat forever.
Payroll
Semi-fixed
Model staffing steps from $940,000 in the first year to $2.2 million in the fifth year.
Treating support hiring as flat forever.
How does break-even shift from lean launch to base and full scale for this investment platform?
Scenario table
Year 1 pricing ranges from $9 to $29 for buyers and $49 to $249 for sellers, while customer acquisition cost falls from $150 to $85 for buyers and $1,200 to $650 for sellers by Year 5, so scale helps only if acquisition cost drops faster than spend grows.
Planning assumptions only; actual break-even will move with mix, spend, and trading volume.

What breaks the break-even plan first for this investment platform?
Stress test
The plan is most fragile if funded accounts and trading volume slow. A 20% revenue miss, a 10% burn increase, or margin slipping to 77% pushes monthly break-even to about $678k-$701k; the combined shock leaves roughly a $182k gap.

What should the founder verify before funding the first platform build and launch spend?
Founder checklist
Don’t commit the $500K build or the first big acquisition push until the rails, controls, and unit math are real. This model still shows a $4.227M cash trough in Month 17, a Month 18 break-even, and Year 1 EBITDA of -$3.371M.
1Build Gate$500K build
Verify the regulatory path and product scope before funding initial platform development, because the first build only pays back if the platform can legally support the assets you plan to trade.
2Control Stack$150K + $8K/mo
Verify know-your-customer, anti-money-laundering, fraud monitoring, and the $150K security setup with $8K monthly cybersecurity before acquisition spend, because weak controls burn paid traffic.
3Trade Rails$100K integration
Verify clearing, custody, execution, payment processing, and the $100K compliance software integration before the first trade, because launch demand only matters if money can move cleanly.
4Margin Load82% CM
Verify the model keeps about 82% contribution margin after market data, trade execution, digital marketing, and compliance costs, because that spread has to cover $69K a month of fixed overhead.
5Cash Buffer$4.227M low
Verify reserves can carry the $4.227M cash trough in Month 17 and the $940K Year 1 payroll only against milestones, while support scales from 1 FTE to 5 by Year 5.
6CAC Proof$150 / $1,200 CAC
Verify buyer CAC at $150 and seller CAC at $1,200 before approving the $3.0M buyer and $1.5M seller Year 1 marketing budgets, because growth only works if acquisition stays on plan.
