FAQ

Frequently Asked Questions

Direct answers about Devs & Logics for founders and product teams.

What is Devs & Logics?

Devs & Logics is a US registered software development agency that builds SaaS MVPs, web and mobile apps, AI integrations, and cloud infrastructure for startups. See all services we offer.

How much does a SaaS MVP cost?

Our fixed-scope SaaS MVPs range from $4,900 to $22,000+, structured across clear architectural tiers. A Lean Single-Tenant V1 ($4,900-$7,500) ships in 3-4 weeks with one core workflow, auth, and Stripe billing. A Growth AI SaaS build ($8,500-$13,500) adds production RAG pipelines and third-party CRM/ERP integrations in 5-6 weeks. Full Multi-Tenant B2B platforms ($15,000-$22,000+) include PostgreSQL Row-Level Security (RLS), RBAC, audit logs, and per-seat metering. Want to validate your scope first? Start with our 5-Day Architecture & Clickable Prototype Sprint ($499)—credited 100% toward your build. Read the full 2026 SaaS MVP cost guide.

How long does it take to build a SaaS MVP?

A scoped SaaS MVP typically takes 4-8 weeks: discovery and architecture in weeks 1-2, core build in weeks 3-6, then billing, auth hardening, and production deployment. Complex AI or compliance requirements can extend this.

Where is Devs & Logics based, and who does the work?

Devs & Logics is operated by DEVSANDLOGICS LLC, a Wyoming registered US company. Our engineering team serves clients across the United States.

Does Devs & Logics work with startups?

Yes. We specialize in startup MVPs with auth, Stripe billing, core workflows, and deployment, for founders in New York, Boston, Miami, Austin, San Francisco, Chicago, Seattle, and Los Angeles.

What tech stack do you use?

Our default stack is Next.js, TypeScript, React, PostgreSQL or Supabase, Stripe, and Vercel or AWS. Mobile projects use React Native. AI work uses OpenAI APIs, vector databases, and evaluation pipelines, chosen per product.

Can you add AI features to an existing product?

Yes. We integrate LLM APIs into SaaS products: RAG knowledge bases, chat agents, workflow automation, and cost controls, built on production Next.js and Node.js backends. See our AI development service.

Do you build mobile and web apps together?

Yes. We build React Native mobile apps and Next.js web platforms that often share one API layer, ideal when you need iOS, Android, and a web admin from a single team.

What happens after my MVP launches?
