What we said about each
What we said about The Ergonomen
"The 9 published case studies document method, not just outcomes: the Viseca credit-card project runs a behavioral-economics workshop, three Figma prototype variants per device, and a quantitative experiment with roughly 400 participants before naming a winning design, and a Zurich-Oerlikon usability lab with a paid test-participant pool (CHF 50-100 per session) backs the research claims. Quantified results are thinner across the set—Schindler reports a 9. 22% conversion lift over six months…"

"Every Interaction publishes 33 case studies in a public gallery spanning fintech (goHenry, Invstr), property (RICS, Athena) and B2B tools (SureCloud, Craft), making this one of the larger portfolios among London independents its size. The case studies themselves run shallow—two or three sentences plus UI screenshots, with no research artifacts, usability findings or before/after metrics shown inside the pages, even though the published methodology lists user research, card sorting and usability…"

Strengths and watch-outs
Both upsides and risks, straight from our editorial assessments.
The Ergonomen
✓ Strengths
- •9 detailed case studies with named clients across finance/insurance (Viseca, Migros Bank, SWICA), public sector (Notariat Zurich, Obergericht), and energy (CKW, KVA Thurgau).
- •Documented research infrastructure: a usability lab in Zurich-Oerlikon and a paid test-participant pool (CHF 50-100/session), with one experiment running ~400 participants.
- •Method is visible end-to-end in at least one case—behavioral-economics canvas, three prototype variants per device, statistical analysis—plus a 9.22% conversion lift reported for Schindler and two Best of Swiss Web 2023 silver awards.
⚠ Watch-outs
- •Ask for participant counts and before/after metrics on cases beyond Viseca and Schindler, since several studies describe the method but omit sample sizes and quantified outcomes.
- •Confirm recent work, since no published case carries a date later than 2023; request 2024-2025 references during the pitch.
- •Scope the engagement in CHF and clarify lab versus remote testing costs, as this is a Swiss Zurich-based firm and rates may sit above the directory's listed range.
Every Interaction
✓ Strengths
- •33 public case studies across fintech, property and B2B SaaS, giving broad evidence of product-UI range
- •Offers interim UX Director, Design Director and in-house UX designer placements alongside project work, useful if you need to plug a team gap
- •Founder-led since 2011 with a published 6-step process (workshop, research, wireframe, prototype, design, test)
⚠ Watch-outs
- •Case studies show final UI but no research or usability-testing artifacts—ask to see the discovery and testing work behind a project similar to yours
- •No project dates are published and several clients appear dated; request recent, dated case studies before shortlisting
- •Homepage cites outcome metrics (for example "210% increase in enquiries") that are not substantiated within the case study pages—ask for the source and context
