WHO WE ARE

Built to solve hard problems

Xephyr builds sovereign AI agents and the data platforms that power them, inside your environment, under your governance.

OUR STORY

From insight to impact

Xephyr was founded by three people who spent years inside some of the most innovative data and AI organisations in the country, including Quantium. When they stepped out, they saw how wide the gap had grown between how those organisations work with data and AI and how everyone else does. We built Xephyr to close that gap.

We didn’t bolt AI onto a legacy consulting model. We started from AI and built outward. Our agent stack lets us move faster than a traditional analytics team, and we ship production systems instead of slide decks.

PRACTITIONERS, NOT SLIDEWARE

The people who scope your work are the people who build it

We are practitioners. The people who scope your work are the people who build it and the people who have done it before, in retail, retail media, banking, telco, health and government. We have sat on your side of the table, run the teams, carried the P&L and shipped the systems. That lived experience is why our advice holds up when your team applies it.

OUR VALUES

What guides us

Human progress

Our work should positively impact human progress. We should progress our own development, especially in human-centred skills.

Iterate quickly

We are a start-up; things change quickly. Start even when you have imperfect information and improve over time. Work more efficiently by bouncing things off each other and getting quick feedback loops.

Further together

We will go further when we operate as a team rather than alone. Leverage our partners and network to help each other reach our goals.

Be dependable

Your teammates rely on you doing your part. Do what you say and say what you will do.

Have fun

Encourage and uplift each other. Celebrate successes and encourage peers, contributing to a motivating and fun work culture.
