About
Design-led product studio building e-commerce platforms, mobile apps and B2B software end to end, from strategy through front- and back-end development.
Who They Work With
E-commerce brands and B2B SaaS teams buying design plus front- and back-end build from one team—see Hey Harper, mishmash, CometChat.
Based on 13 documented clients · verified Aug 2026
Our Take
More than 20 client case studies are published, and at least six close with outcome numbers rather than screenshots: mishmash reports a 212% sales lift and 34% conversion gain, Hey Harper 17% conversion in its EU store and around €3M in added revenue at one month's payback, Coffee King 29% conversion and 38% average order value two months after launch, and CometChat 50% more demo requests.
Case studies list front-end and back-end development alongside design and brand work, so this is a build partner rather than a design-only shop, and five projects carry Red Dot, iF, German Design Gold or European Design Gold awards.
Research is referenced in most write-ups but the artifacts are not published—no interview counts, personas, test protocols or wireframe sequences appear on any project page—so what you see is the problem framing, the finished interface, and the result.
The weaker fit is buyers who need research deliverables as a contract output, or whose budget sits below the €50,000 project floor published on the quote page.
Key strengths
- Outcome reporting is consistent across verticals, not just commerce: allO documents a 30% sales increase and 25 minutes saved per shift in back-office work, and Diesta a 50% reduction in manual reconciliation after launch.
- Four projects were published in 2026 (Coffee King, Diesta, Petzai, FC Porto hospitality), and the blog has run 10 posts since April 2026, mostly on AI in discovery and prototyping.
- Operating signals are verifiable: B Corp certified and a 1% for the Planet member, trading since 2016 from a street address and landline, roughly 35 people listed, and a fully public company handbook covering design ethos, engineering practice, NGO pricing, and its AI policy.
Good to know
- Research is referenced but no discovery artifacts appear on any project page—ask to see interview notes, a test plan or a wireframe sequence from a recent project before assuming discovery sits inside your quote.
- Conversion and revenue figures are published without a stated measurement window or control—ask how each lift was isolated from seasonality and paid-media spend, especially on the e-commerce replatforms.
- Strategy, brand, design, and both front-end and back-end sit under one roof at roughly 35 people—confirm how many are assigned to your project at once, and whether design and engineering run concurrently or in sequence.
