Running an online store means dealing with disconnected tools: payment service providers, multiple shipping providers, managing refunds, and a bunch of other tools for everything that can go wrong in between. None of them talk to each other, and most weren’t built with small businesses in mind.
‍
We started in 2018 with a clear frustration: small businesses were stuck managing checkouts, payments, and fulfilment through a messy patchwork of tools – expensive to run, complex to scale, and built for someone else. So we built an alternative.

Today, over 7,000 merchants across the Baltics and Poland use Montonio to handle checkout, payments, shipping, refunds, and post-purchase operations through one unified system. No juggling platforms, no stitching together half-solutions. Just one stack that works as a whole.

We’re a 65-person team building across product, engineering, operations, and merchant support. We’re proud to be a Series A company backed by Index Ventures, Superangel, and early builders from companies like Wise and Bolt.

Our mission is to give small and mid-sized merchants the tools to be successful, while lowering their cost of ownership and giving them back time, control, and headroom to grow.

We believe the future of ecommerce isn’t about adding more tools. It’s about making the right ones work together.
