Corporate vs RapidDevAI: The Hidden Costs

A traditional corporate team would incur costs that extend far beyond simple developer salaries:

Cost Category Timeline Cost
Pre-Development (Approvals, Requirements) 2-4 months Unpaid waiting (no delivery)
Team Assembly (Hiring, Onboarding) 4-8 weeks $25-40k
7-Person Team (18 months) 540 days @ $1k/day/person $540k
Overhead & Processes (PM, meetings, tools) Continuous (40% of dev) $216k
Contingency & Buffer (15%) Throughout $28k
TOTAL 18-24 months $800k-$1M
RapidDevAI Cost 4-5 months $100-120k
SAVINGS 12-18 month head start $680-900k

The Real Advantage: While a corporate team is in pre-development approval cycles (2-4 months with no deliverable), Brendan already has a revenue-generating product in market with real customers. This 12-18 month head start is an invaluable competitive advantage no amount of money can buy back.
