About Firstbase.io

Firstbase is building an all-in-one Company OS to help define how founders across the globe launch, manage and grow their businesses. More than ten thousand founders from over a hundred countries have used our product, Firstbase Start, to launch their startup. For many founders, "firstbase.io" has become what they type into their address bars when they think about incorporating a business.

About the role

About Firstbase

Tens of thousands of businesses — from newly incorporated startups to public enterprises — rely on Firstbase to streamline compliance, finance, analytics, and every part of the back office. It is one platform to run your entire company.

Our goal is to make running a business feel like magic. We make it possible by owning the general ledger and unifying data across all business functions. Compliance tasks are flagged — and often resolved — automatically. Real-time business metrics are accurate, accessible, and easy to understand. And if you need to hire a new employee, send an invoice, or file taxes, you can do it from the same interface.

We’re bundling what’s never been bundled. We’re not building an incorporation tool. We’re not building an ERP. We’re not building an "AI accountant." We are creating a new category entirely: the Company OS.

How we work

We cherish the moments when noise fades and we move with clarity, confidence, and focus — doing the right thing at the right time. These moments are when our best work happens, and we strive to create more of them.

We value craftsmanship over busyness, clarity over complexity, and resilience above all — whether it takes hard work or patience. We aim high, avoid mediocrity, and speak with fearless transparency.

We believe in upward mobility and take pride in growing talent from within, always preferring to promote our own before looking externally.

About the team

We are a lean and highly collaborative group of engineers who play a central role in shaping product decisions and delivering an exceptional experience to a global audience of founders. We value clean, well-tested code, thoughtful reviews, and simplicity in everything we build. From writing production-grade Golang services to owning end-to-end software projects, we work closely together to drive clarity, scalability, and impact.

Our product is built using PHP, Golang, Node.js, Vue, MySQL, PostgreSQL, AWS. We also use Redis, Vue Router, Vuex, Docker Compose, Docker, GitLab CI, and Graylog, and some third-party API's like Stripe. We use Slack, Clubhouse, Notion, Whimsical, Figma, and G Suite to collaborate and build together.
