Failing Forward: Lessons From a Failed Tech Startup on Building Your Next MVP

Embracing failure is not a concept that comes naturally to many of us. However, in the fast-paced world of tech startups, where the terrain is as unforgiving as it is unpredictable, failure can be a profound teacher. My journey through the rise and fall of a tech startup has been a crucible of learning, especially in the realms of building and scaling a Minimum Viable Product (MVP). This reflection is not a tale of regret but a beacon for those embarking on their own tech ventures.

The Initial Spark: What Went Wrong with Our Tech Stack Choice

Selecting the right tech stack for your MVP is akin to laying the foundation for your future house. It dictates not only the immediate feasibility of your project but also its long-term scalability and maintenance. Our journey began with enthusiasm and a bias towards using the latest and greatest technologies. We opted for Node.js, enchanted by its promise of full-stack JavaScript development.

// Initial backend setup
const express = require('express')
const app = express()
const port = 3000

app.get('/', (req, res) => {
  res.send('Hello World!')
})

app.listen(port, () => {
  console.log(`Example app listening at http://localhost:${port}`)
})

This simple server setup was our starting point, chosen for its ease of use and the vast ecosystem of Node.js. However, as we scaled, the decision to not consider TypeScript for static typing and to disregard other backend technologies that offered more out-of-the-box scalability features became our Achilles' heel.

Scaling Prematurely: A Cautionary Tale of Growth vs. Stability

In the excitement of early user traction, we made the critical mistake of scaling prematurely. Our infrastructure was not ready, and our choice of tech stack, coupled with our architectural decisions, made rapid scaling a challenge. We had not anticipated the need for a more robust solution to handle the increasing load and found ourselves struggling with performance issues.

Here's an example of how we could have better structured our code for scalability using TypeScript and a more structured approach to our database interactions, though it's important to note that this requires additional configuration, such as setting up connection options for your database:

import { createConnection } from 'typeorm'

createConnection({
  // Actual configuration details are necessary including host and potentially other options depending on the environment
  type: 'postgres',
  host: 'localhost',
  port: 5432,
  username: 'user',
  password: 'password',
  database: 'mydb',
})
  .then((connection) => {
    app.get('/', async (req, res) => {
      const users = await connection.manager.find('User')
      res.json(users)
    })

    app.listen(port, () => {
      console.log(`Server running at http://localhost:${port}`)
    })
  })
  .catch((error) => console.log(error))

This snippet reflects an evolution towards using TypeScript for static typing and integrating an ORM for database interactions, which we learned was crucial for maintainability and scalability.

Pivoting with Purpose: Lessons in Adapting and Iterating Your MVP

Pivoting is not admitting defeat; it's about strategic adaptation. Our journey taught us the importance of being flexible with our MVP and the need to iterate based on user feedback and technical constraints. A significant pivot for us was reevaluating our tech stack and incorporating more robust technologies and patterns that could scale with us.

import express, { Request, Response } from 'express'
import { NextFunction } from 'express'

// Example error handler implementation (to be customized)
const errorHandler = (error: Error, req: Request, res: Response, next: NextFunction) => {
  console.error(error)
  res.status(500).send('An unexpected error occurred')
  next()
}

const app = express()
const port = 3000

app.get('/', async (req: Request, res: Response) => {
  try {
    // Business logic here
    res.send('Successfully refactored our approach.')
  } catch (error) {
    errorHandler(error, req, res, next)
  }
})

app.listen(port, () => {
  console.log(`Refactored app listening at http://localhost:${port}`)
})

This example showcases a more mature approach, incorporating TypeScript for better type safety and a middleware for error handling, signifying our growth in understanding and implementing more sophisticated coding practices.

Building Anew: Key Takeaways for Future Founders on Technical Decisions

The journey of building, failing, and learning has been invaluable. Here are some distilled lessons for future founders:

1. Choose Your Tech Stack Wisely: It’s tempting to go with what’s trending, but assess the long-term maintainability and scalability. Starting with JavaScript and Node.js is great, but be open to incorporating TypeScript and other technologies as you scale.
2. Embrace Static Typing Early: TypeScript can save you from countless bugs and headaches down the line. It’s worth the initial investment.
3. Scale Thoughtfully: Understand your MVP’s limits and scale in response to actual, not anticipated, growth. Premature scaling can strain your resources and infrastructure unnecessarily.
4. Iterate Based on Feedback: Be prepared to pivot and refine your MVP. Adaptation is key to survival and growth in the tech startup ecosystem.
5. Invest in Good Coding Practices: As shown through our evolution, incorporating better error handling, modularization, and static typing were crucial steps in maturing our codebase.

In conclusion, the path through failure is fraught with valuable lessons. Our experience, though challenging, has been a profound teacher. For those embarking on building their next MVP, remember that every line of code, every technical decision, and every pivot is a step towards a future where failure is not an endpoint but a milestone in the journey of innovation and success.
