YouSir
Amsterdam, Netherlands
About
SaaS-focused UX design studio turning product gaps into revenue growth.
Our Take
YouSir publishes 4 detailed SaaS case studies, each documenting a clear audit-to-redesign pipeline. The Signhost project shows 7 user interviews, 200+ user usability tests, A/B testing with 250+ users, and a +250% conversion improvement. The Adswag UX audit reviewed 26 screens, produced 200+ insights and 5 key opportunities, then transitioned into a full redesign. HROffice went from 7-week foundation phase through user interviews to first beta in 4 months. Producthero involved design thinking workshops, UX audit, and user research that transformed the organization into a UX-driven company.
The consistent pattern across all projects—audit first, then research, then design system and implementation—demonstrates a repeatable methodology rather than one-off success.
Best for B2B SaaS companies that need a UX audit tied directly to conversion and product growth—particularly if you want a partner who stays through implementation with measurable outcomes.
Key strengths
- 4 published SaaS case studies with consistent audit-to-redesign methodology: Signhost (+250% conversion), Adswag (26 screens, 200+ insights), HROffice (discovery to beta in 4 months), Producthero (full UX transformation)
- Research depth across projects: user interviews, usability testing (200+ users), A/B testing (250+ users), competitor analysis, and design thinking workshops
- Audit engagements consistently evolve into ongoing partnerships with design systems, branding, and implementation support
Good to know
- No published rates—request pricing early
- Narrow SaaS focus means this may not be the right fit for eCommerce, marketplace, or non-SaaS product audits
- Case studies report process metrics (screens reviewed, insights generated) but Signhost is the only one with published business outcomes—ask for conversion/adoption data from other projects
