We are
Zentra
AI led ecommerce agency
Based in the UK & USA
Designers and developers, powered by AI.
From first sketch to live store, under one roof.
Every decision measured against your conversion rate.

We make ecommerce stores convert.

12+ years of design experience
Zentra is a team of designers and developers who build with AI at every step. AI does the heavy lifting: research, first drafts, product photography and testing at scale. Our team does the judgement: what your customers need to see, what earns their trust and what makes them buy.

That combination lets us move faster and charge less than a traditional agency while holding the work to a higher standard. New brands get a store that looks established from day one. Established brands get a site that turns more of the traffic they already pay for into orders.

We’ve built and sold direct to consumer brands of our own, so we know what a point of conversion is worth. It’s why every quote we give comes with the payback attached.
(01)
Start from the numbers
Traffic, conversion rate and order value come first. They decide what we design and in what order.
(02)
AI for speed, people for taste
AI gets us to a strong first version fast. Designers and developers make it right.
(03)
Prove the lift
We measure before and after, and report the change in conversion rate in plain numbers.
