SaaS Development for Startups and Scaleups
SemeLabs designs and builds cloud-native SaaS platforms end to end: multi-tenant architecture, subscription billing, role-based access, admin dashboards, and API-first integrations. We take products from MVP to scale on React, Next.js, Node.js, and AWS — including AI and LLM features built in from day one.
What we build
- Multi-tenant architecture and user management
- Subscription billing and payment integration (Stripe and others)
- Admin dashboards, analytics, and reporting
- API-first design for third-party integrations
- Cloud deployment on AWS, Vercel, and GCP
- AI-native features: LLM assistants, RAG search, automation
From MVP to scale
For early-stage teams we scope and ship a focused MVP fast, with an architecture that won't need a rewrite when you grow. For established products we modernize, harden multi-tenancy, and add the features your roadmap needs.
Our teams work across 15+ countries and ship with TypeScript, React, Next.js, Node.js, PostgreSQL, Redis, and Docker — with CI/CD on GitHub Actions from the first sprint.
Frequently Asked Questions
How long does it take to build a SaaS MVP?
A focused MVP with authentication, billing, a core workflow, and an admin panel typically ships in 6–12 weeks depending on scope. We define the cut-line together in a free scoping session before any commitment.
Do you build multi-tenant SaaS platforms?
Yes — multi-tenancy is our default architecture: tenant isolation at the data layer, role-based access control, per-tenant billing and usage metering, and admin tooling to manage tenants.
Can you add AI features to a SaaS product?
Yes. We integrate LLM features (OpenAI, Anthropic Claude, LangChain, RAG) directly into the SaaS data model and permissions, so AI capabilities respect tenant boundaries and billing from day one.
What technology stack do you use?
TypeScript, React, Next.js, Node.js, and Python on the application side; PostgreSQL, Redis, and Pinecone for data; AWS, Vercel, Docker, and GitHub Actions for infrastructure and delivery.
