How long does it take to build a SaaS from scratch?

MVP: 12–16 weeks. Full production SaaS with mobile, AI, and compliance layers: 20–24 weeks. You receive a committed launch date in the proposal — not a rolling estimate that shifts every sprint.

What's the best tech stack for a custom SaaS in 2026?

React + Next.js + TypeScript on the frontend. Node.js or Laravel on the API. PostgreSQL for the database. AWS for infrastructure. Flutter for cross-platform mobile. Claude or OpenAI + LangGraph + Pinecone for AI workloads. We match the stack to the build — this is our default, not a one-size-fits-all answer.

Should I hire a SaaS agency or build in-house?

Two mid-level US engineers cost roughly $260K per year — before equity, benefits, or onboarding time. Our MVP Pro engagement ships a production SaaS in 12–16 weeks. Most mid-market clients run hybrid: we ship the foundation, they hire 2 engineers to operate and extend it. We can help you structure that handoff.

What's the difference between multi-tenant SaaS and a custom web app?

Multi-tenant SaaS means one codebase serving many customers on subscriptions — with tenant isolation, billing, and usage limits baked into the architecture. A custom web app is one codebase serving one customer's workflow. Both are browser-delivered, but the architecture, data model, and pricing are completely different. We scope accordingly.

Can you add AI agents to my existing SaaS?

Yes — that's our AI Agent service line. We build RAG pipelines, agentic workflows, voice agents, and LLM features into existing platforms. We wire in eval harnesses, observability, and a real ROI model so you can measure what the agent is actually doing.

Who owns the code after delivery?

You do, 100%. IP transfers on final payment. Your GitHub repository, your cloud account, your App Store listing. No licenses, no revenue shares, no vendor lock-in of any kind.
