About Us

We are developing a next-gen integration platform that allows SaaS businesses of any size to integrate their product with third-party products in a fast, powerful, and secure way.

🎖️ Our vision

The number of SaaS companies is exploding. But making great integrations is still too expensive and slow. We are building StackOne to solve this and become the platform that powers a connected ecosystem of apps that customers love.

💪 Well-funded and backed by top-tier angels and VCs, we're now growing extremely rapidly and we are currently raising a multi-million dollar round. We're seeking talented and driven individuals who can help us achieve our vision and continue to grow the product and the overall company at a record pace.

In this role, you will conduct research and development around AI, focusing on automating processes and development at StackOne. We're building a world where users of any SaaS can integrate with the tool of their choice in one click thanks to StackOne. We're convinced AI is pivotal to making this a reality by transforming how SaaS talks to each other and this is what you will help achieve.

🚀 Product

StackOne is one of the fastest-growing embedded integration platforms. Here’s why:

It drives down the cost of building integrations by 10x. To add dozens of integrations, you only need to integrate once with our unified API and we take care of the rest. This is way faster, cheaper, and more reliable than building every integration to each tool one at a time (it can take weeks/months per integration).
It has a superior architecture: Unlike other Unified APIs, we developed an innovative, fully real-time architecture that does not store their customers’ sensitive data by default. This enables our customers to differentiate themselves on the market with better integrations: better for privacy, better for their product’s user experience, and deeper read/write integrations.
StackOne is a better long-term partner: We are the only integration platform to guarantee new integrations as standard, that offers so many sandboxes to support testing and deploying faster, and that has built a strong partnership ecosystem to enable our customers to develop stronger commercial partnerships.
