Why Polar?
It's never been easier to build, ship and scale software.
But it's never been harder to monetize it.
We're obsessed over solving this to empower the future one-developer unicorns.
These unicorns will be rare but inevitable. Whether in 3, 5, or 10+ years, they also symbolize a broader shift already in motion and accelerating:
Smaller & smaller teams with...
Exponential revenue/employee growth
Focusing fully on their core product and marketing. Delegating & automating everything else that's boilerplate – be it in their codebase or business operations.
Exceptional billing primitives, APIs, SDKs and abstractions are a crucial foundation, but not enough. They will need a full-fledged platform to oversee, manage and scale their business.
Turning their software into an international business in 6 lines of code.
Join our small, talented and engineering-led team across Europe to shape how future software businesses are built. We focus on shipping at high velocity to serve developers in unlocking their next stage with their business. Everything else is secondary.

So you'll be given a lot of agency and autonomy to move fast towards our mission and serving our developer community.

What We Do
It’s never been easier to build software. From open source having pushed the envelope of developer velocity to AI now accelerating the trend and making software development accessible to more people.
It’s never been easier to ship and scale software. Cloud platforms and modern PaaS solutions like Vercel and Supabase have drastically simplified global software deployment and scaling.
But, it’s never been harder to monetize software. We've moved from one-time purchases to SaaS, and now toward usage-based and agentic payments. Each evolution has enabled new category defining businesses, but also added complexity and billing anxiety for developers and their customers alike.
This is a bottleneck for the future.
We believe the next unicorns will be created by individual developers. As lines blur between indie hackers, startups, and enterprises, we're building Polar to empower solo builders and early-stage startups – the future enterprises, without the headcount. How?
Monetization vs. Billing Platform. Billing is a crucial part of your customer relationship, but only a part of it - it's the outcome vs. input. We aim to bridge the gap between product analytics, CRM, and billing, providing a comprehensive platform for one-developer unicorns to scale their businesses.
Usage-based on Autopilot. Automatic event ingestion for OpenAI, Anthropic, Vercel AI SDK to S3 consumption and more – easily track, credit and bill customers for their usage. We’re going to ship a lot of innovative features in this category to make usage-based and agentic payments a delight for developers and their customers.
Zero Boilerplate. We obsess over reducing the lines of code in your codebase that aren't unique to your business, from automating common SaaS entitlements like license keys and usage-based credits to condensing integrations down to just four lines of code.
Zero Operations. Grow globally without being held back by international sales tax, compliance, fraud, or chargeback protection.
