MVP ready for your first paying customers
Pilot users said yes. Now you need Stripe, auth, and a backend that survives real usage. The Core Engine is scoped to charge your first customer in your AWS account with fixed price and fixed deliverables.
What first-revenue MVPs must include
First paying customers need identity, billing or invoicing, reliable APIs, and admin visibility. The Core Engine Full SaaS tier targets that minimum with serverless AWS components you own. You avoid no-code ceilings and freelance patchwork. When AI becomes part of the value prop, add The AI Cortex on the same platform.
Which product fits your stage
| Stage | Product | Outcome |
|---|---|---|
| Fundraising / pre-revenue | The Starter Engine | Minimum production system on your AWS account |
| First customers / revenue | The Core Engine | Serverless SaaS with auth, payments, and admin in your AWS account |
| Owned enterprise AI | The AI Cortex | Bedrock RAG pipelines and guardrails in your AWS account |
From pilot yes to production invoice
Pilots break when login, billing, and support tooling are held together with manual ops. Full SaaS tier wires the minimum production path so customer one pays through your product, not a workaround.
You choose AWS region and Stripe or invoicing flows during scoping. Fixed price covers the tier, not open-ended feature hours.
Full SaaS versus Scale
Full SaaS gets you charging quickly with auth, APIs, and hosting. The Scale tier adds multi-tenant architecture, advanced roles, and operational headroom when customer two through ten need more maturity.
Smart Trady shows what Core Engine plus AI Cortex looks like at scale. Start with the tier that matches your next 90 days, not a hypothetical Series B roadmap.
