A studio building high-performance web apps, commerce platforms and SaaS products — engineered with the precision of a product team and the polish of a design house.
Most software is built for the demo. Ours is built for year five — fast on day one, faster at scale, and engineered so it never has to be rebuilt from scratch.
Three disciplines, one studio
Modern frameworks, edge rendering, clean architectures. Apps that stay fast at scale — from internal tools to consumer products.
Custom storefronts with seamless checkout, inventory orchestration and analytics that actually guide decisions.
Subscription platforms with auth, billing, roles and robust APIs that third parties love to build on.

A selection of recent engagements, each built to move a real business metric.
A real-time 3D showcase for an on-demand knitting platform — garments presented as living geometry the visitor can orbit and explore in the browser.
An interactive experience for an AI-driven product company — scroll-composed scenes and generative visuals rendered live, so the site demonstrates the product's intelligence instead of describing it.
A storefront for a Tokyo lifestyle brand where editorial art direction meets frictionless checkout — quiet layouts, exacting typography, and a purchase flow that never breaks the mood.
Built a context-aware LLM pipeline that handles 80% of tier-1 support queries for a mid-market retailer, integrated directly into their custom Zendesk environment.
Every tool picked for performance, longevity and developer experience.
We interrogate the problem. Stakeholder interviews, an audit of existing systems, competitive mapping — and a clear success metric before a single pixel is drawn.
Product architecture, user flows, a full design system and prototype. Every decision pressure-tested against the success metric from phase one.
Senior engineers only. We build in weekly slices against a staging environment you can click through from day one. No black-box development.
Launch is the midpoint, not the finish line. We instrument, measure, iterate — and hand over ownership-grade documentation so the product outlives the engagement.
“Zeriotic turned our product site into something that feels alive — real-time visuals that actually demonstrate what we do instead of describing it. Time-on-page more than doubled and demo requests climbed with it.”
“They engineer the way a product team engineers — not the way an agency engineers. Our AI assistant launched with real observability and an upgrade path from day one.”
“They treated our product with the reverence it deserves. Every garment renders in real time, thread by thread — customers explore before they buy. Nothing else on the market comes close.”
Zeriotic is an independent studio of sixteen. We take on a handful of engagements each year — enough to stay sharp, few enough that senior people do the actual work. No account managers, no subcontractor shuffle, no juniors learning on your budget.
We work with founders who want a partner that treats their product like our own, and teams who want the polish of a design house with the rigour of a product engineering group.
Formerly lead engineer on high-traffic commerce platforms. Specialises in performance and architecture.
Twelve years designing interfaces for SaaS and luxury retail. Brand, systems, and typographic obsession.
Full-stack, infra-first. Loves Postgres, caches, and anything that makes a server respond faster.
Brings interfaces to life. WebGL, GSAP, and the discipline to know when to cut motion entirely.
We take on a handful of engagements each quarter. If you're shipping something ambitious, we'd love to hear about it.
