What's the story behind your product?

ConfigCat's answer:

ConfigCat started in 2018 when a small team of developers set out to solve a problem they'd experienced firsthand: changing application behavior shouldn't always require a new deployment.

The company was bootstrapped from day one, with the founders leaving their jobs to build a feature management platform that was simple, reliable, and affordable.

The first year wasn't easy. ConfigCat didn't get its first paying customer until 2019. But gradually, developers began discovering the platform, appreciating its straightforward approach and transparent pricing.

What started as a small engineering project grew into a feature flag platform trusted by development teams around the world.

Despite that growth, the original philosophy hasn't changed: powerful tools don't have to be complicated, and great customer support should be part of the experience.

Which are the primary technologies used for building your product?

ConfigCat's answer:

ConfigCat is built using technologies including:

  • .NET / C# for backend services and APIs
  • Angular and TypeScript for the management dashboard
  • MySQL for database management
  • Cloudflare CDN for fast, globally distributed configuration delivery

ConfigCat also provides open-source SDKs for popular programming languages and frameworks, enabling fast, local feature flag evaluation without requiring a network request for every flag check.

Who are some of the biggest customers of your product?

ConfigCat's answer:

  • Nasdaq
  • Rakuten
  • Schneider Electric
  • Electrolux
  • FlixBus
  • Heineken
  • Knab
  • Baillie Gifford
  • OneSignal
  • InfluxData
