About the role
About Lago
At Lago, we're on a mission to make Monetization simpler for tech companies.
As the leading open-source billing platform, we help businesses 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.
Our platform has garnered around 10K stars on GitHub, a testament to our active and growing developer community. Companies such as PayPal, CoreWeave, Synthesia, and Mistral.ai choose Lago for their billing. And we have barely spent any money on Marketing or Ads so far.
We're a team of ambitious, focused individuals who 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 continuously improve them. 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.
