About Lago
At Lago, we're on a mission to make billing simpler, more transparent, and more adaptable for SaaS companies. As the leading open-source billing platform, we empower businesses to build flexible pricing models and scale with confidence. We've raised over $22 million in funding from top-tier investors including Y Combinator and FirstMark, reflecting strong confidence in our vision and growth. Our platform has garnered over 9,000 stars on GitHub, a testament to our active and growing developer community. Companies such as PayPal, Synthesia and Mistral.ai choose Lago for their billing. We're a team of ambitious, focused individuals who work together to solve hard problems with excellence and accountability. At Lago, we value reliability and proactivity - we trust each other to own tasks, drive them to completion, and adapt quickly. While we encourage you to try fast and "fail fast", we also expect you to learn fast: make mistakes, but don't make the same one twice. If you're excited by challenges and want to grow alongside a high-performing, supportive team, this is the place for you.
