Path to Millions: How Choosing Kotlin Changed a Startup's Fate
The startup world is full of stories about rises and falls. However, projects that bet on unconventional technological solutions from the very beginning deserve special attention. One such story is the company «CodeBridge», a young team of developers who built a successful SaaS product using Kotlin. Today, their service is used by more than 50,000 companies worldwide, and the startup's valuation exceeds 200 million dollars. How did they manage it?
Why Kotlin?
When the founders of «CodeBridge» conceived the idea of creating a platform for business process automation in 2018, they faced the classic choice: Java, Python, or C#. However, the startup's CTO, who had experience working with JetBrains, proposed a risky option — Kotlin. At that time, the language was just gaining popularity, but it already had a number of advantages:
- Compatibility with Java — it was possible to use the vast ecosystem of libraries without rewriting code.
- Conciseness and safety — Kotlin reduced the amount of code by 30% compared to Java, and the Null Safety system prevented thousands of potential errors.
- Powerful coroutines — asynchronous data processing allowed handling requests 4 times faster than competitors.
- Kotlin Multiplatform — the ability to write common code for the backend, web, and mobile applications.
Key Stages of Growth
The story of «CodeBridge» is not just about a lucky choice of language, but a well-thought-out strategy. For the first two years, a team of 10 developers worked in a "garage startup" mode, but by the end of 2020, they had already released an MVP (Minimum Viable Product). Here is what helped the company take off:
- Development speed. Thanks to Kotlin, features were released 2 times faster than originally planned. This allowed them to outpace competitors in the market.
- Low entry barrier for the team. Developers with Java retrained to Kotlin in 2-3 weeks. The company didn't waste time on lengthy onboarding.
- Performance. Kotlin coroutines handled peak loads when 10,000 clients were using the platform simultaneously.
- Investments. In 2021, the venture capital fund Sequoia Capital allocated $15 million to the startup, specifically citing the technological foundation as a key success factor.
Lessons for the IT Community
The story of «CodeBridge» proves that the choice of a programming language can become not just a technical decision, but a strategic advantage. Kotlin today is not only a language for Android but also a powerful tool for creating server applications, web services, and cross-platform solutions. The company's founders advise young startups not to be afraid of innovation: "If we had chosen Java out of conservatism, we would still be polishing the basic functionality. Kotlin gave us the speed and flexibility that became our main weapon."
Today, «CodeBridge» actively uses Kotlin Multiplatform to expand onto mobile platforms, and their team has grown to 200 engineers. The startup has become a clear example of how a modern programming language can turn a small idea into a global business.
