About Us

BlockFactory is leading the adoption of blockchain technology worldwide. Like in every start-up, we’re on a rollercoaster ride, but we’re all here for the same reason: to bring Blockchain to the masses and have some fun along the way!

We’re passionate, excited but also realistic about blockchain and its capabilities. While we’re constantly bantering at the office over which blockchain will rule them all, the technologies and tools we’re developing are chain-agnostic.

At BlockFactory we’ll encourage you to stay curious, inquisitive and constantly learn new skills. That way, should you ever decide to move on, you’re the best version of yourself. We always aspire to hire for the long term and cultural fit is one of the most important factors when we’re recruiting. After all, culture does eat strategy for breakfast!
