Hey! 👋 We’re Xapix
We're a team of nerds. Creatives, developing and designing our product since 2016. We're a mix of different characters and whilst English is the common language across the team, you can try out Hebrew, Polish, Russian, Japanese, and even German with some of us.



What do we do at Xapix?

We are pioneers in the fast-growing eCommerce space helping to level the playing field for sellers and aggregators to compete. Our job is to help entrepreneurs buy & sell eCommerce businesses. Our SaaS offering helps both sides simplify and automate their backend infrastructure, add new intelligence, and help companies reach their goals faster (e.g. by evaluating future performance, screening target sellers, establishing a common platform, and scaling up).

We enable retailers to build a smarter future, faster. Today, we are enabling FBA aggregators to acquire, connect, and scale faster. Tomorrow, all digital-first retailers will be accelerated by our technology.

How do we like to work?

Every team member is heard when it comes to how we do the things we do … (how we work, what we work on, and where we are heading). Our amazing Product Manager Jimmy takes care of creating a clear vision of our product roadmap and is connecting engineering with the business team. We have a “user first”-attitude and don't compromise on that. Sometimes we dive in head first, always planning ahead.

We listen to each other. In our monthly 1on1s with Michael, our CTO, and people-hero Limor we discuss our well-being and ways to improve as a team and company. We want everybody to grow and will support you on the way.
