What US Investors Expect from a SaaS MVP
Seed-stage US investors look for paying customers or strong waitlist conversion — not a 50-feature roadmap. A $45k MVP that validates one workflow beats a $150k platform with zero users.
We built HITEK CRM on MERN for US tint shops — quotes, bookings, deposits, and messaging in one SaaS. That scope is representative of a focused vertical MVP.
SaaS MVP Stack & Cost Efficiency
MERN and Next.js full-stack teams ship fastest for US SaaS. Laravel suits B2B supply and catalog portals. Use Stripe Customer Portal instead of custom billing UI in v1 — saves 3–6 weeks and thousands in dev cost.
