How to Choose the Right Tech Stack for Your Startup

Choosing your startup's tech stack is one of the most important decisions you'll make. The right choices set you up for rapid iteration and smooth scaling. The wrong ones can saddle you with technical debt that slows you down for years.

After building technology for dozens of startups, we've developed a framework for making these critical decisions. Here's what you need to know.

Principles for Choosing Your Stack

1. Optimize for Speed of Development

In the early stages, your primary goal is validating your product and iterating quickly. Choose technologies that let you move fast, even if they're not the 'most scalable' option. You can always optimize later.

“Premature optimization is the root of all evil.”

— Donald Knuth

2. Consider Hiring and Team Capabilities

The best technology is the one your team knows. Factor in the talent pool for each technology—can you hire developers who know it? Is the community active? Are there good learning resources?

3. Don't Over-Engineer

You don't need microservices, Kubernetes, or a complex event-driven architecture on day one. Start simple and add complexity only when you have real problems that require complex solutions.

Our Recommended Stack for 2024

Based on our experience building scalable applications, here's our current recommended stack for most startups:

Frontend: Next.js + TypeScript

Next.js has become the standard for modern web applications. It offers server-side rendering, static generation, API routes, and excellent developer experience—all in one framework. TypeScript adds type safety that prevents bugs and improves maintainability.

• Built-in performance optimization
• Great SEO capabilities
• Incremental static regeneration
• API routes reduce backend complexity
• Massive ecosystem and community

Backend: Node.js or Go

For most startups, Node.js (with Express or Fastify) provides the fastest path to production. If you need high performance or have heavy computational needs, Go is an excellent choice with strong typing and built-in concurrency.

Database: PostgreSQL + Redis

PostgreSQL handles nearly every use case and scales further than most startups will ever need. Add Redis for caching and session management. This combination handles 95% of application requirements.

Infrastructure: Vercel or AWS

Vercel offers the fastest deployment experience for Next.js applications. When you need more control or specific AWS services, AWS Amplify or a custom setup provides flexibility at scale.

Technology Decisions by Startup Stage

Pre-Seed / Seed Stage

Focus entirely on speed. Use managed services wherever possible. Don't build what you can buy. Your goal is proving product-market fit, not building infrastructure.

• Use Vercel or Netlify for hosting
• Use Auth0 or Clerk for authentication
• Use Stripe for payments
• Use a hosted database like Supabase or PlanetScale

Series A and Beyond

Now you can start thinking about optimization, custom infrastructure, and building vs. buying. But only invest in complexity that solves real problems you're experiencing.

Red Flags: Technologies to Avoid

• Bleeding-edge frameworks without production track records
• Languages with small talent pools in your market
• Complex architectures before you need them
• Self-hosting everything when managed services exist
• Multiple databases before you've maxed out one

Making the Decision

The best tech stack is the one that lets you ship quickly and iterate based on user feedback. Don't get paralyzed by analysis—pick proven technologies, start building, and adjust as you learn.
