    Startup Tech Stack Examples

    What technology successful startups use — from early MVP to scaled operations.

    Last updated:

    Your tech stack affects development speed, hiring ability, scalability, and costs. But there's no universal "best" stack — the right choice depends on your product, team, and stage. Here's how real startups at different stages approach their technology decisions, with specific recommendations for Indian startups.

    Early MVP (0-100 users)

    Any

    Typical early-stage startup validating product-market fit. Priority: build fast, iterate quickly, don't over-engineer. Use managed services for everything.

    Next.js or React + ViteSupabase or FirebaseVercel or RailwayTailwind CSS

    Growth Stage (100-10K users)

    Any

    Product-market fit validated, now scaling. Add proper backend, monitoring, and start thinking about performance. Team is 3-8 developers.

    React + Node.js/ExpressPostgreSQL + RedisAWS or GCPDocker + GitHub Actions CI/CD

    Scale Stage (10K-1M users)

    Any

    Rapid growth requiring infrastructure maturity. Microservices may be introduced for specific high-scale components. Team is 10-30+ developers.

    React/Next.js + TypeScriptNode.js + Python servicesKubernetes (EKS/GKE)PostgreSQL + Redis + Kafka

    Razorpay's Stack

    Fintech

    India's largest payments company. Started simple (PHP + MySQL) and evolved to a sophisticated microservices architecture handling millions of transactions daily.

    Java + Go (backend)React (frontend)MySQL + DynamoDBKubernetes + AWS

    Zerodha's Stack

    Fintech

    India's largest stock broker — handles 15M+ orders daily. Known for minimalist, high-performance architecture built with a small team of ~30 engineers.

    Frequently Asked Questions

    Recommended starting stack: Next.js (frontend + API routes), PostgreSQL (database), Redis (caching), Tailwind CSS (styling), TypeScript (everything), and AWS or Railway (hosting). For mobile: Flutter. This stack is well-supported, has great hiring availability in India, and scales from MVP to millions of users.

    Change when: you're hitting genuine performance limits (not premature optimisation), you can't hire for your current stack, the technology is deprecated or unsupported, or specific business requirements demand different technology. Don't change because of hype or because "everyone is using X". Rewrites are expensive — make sure the current stack is truly limiting you.
