Led the complete redesign of the platform twice across all user types (retailer, vendor, VC, enterprise retailer), managed an in-house designer, contributed to product strategy and roadmapping, and designed marketing sites and supporting materials alongside the core product work.

Cohere Commerce helps retail buyers find new brands to stock. Instead of sourcing through trade shows and cold outreach, buyers use the platform to discover and evaluate brands using AI-powered data and peer reviews. We worked with the Cohere team for two years as their design partner, helping build and improve the product throughout.
The platform had four very different types of users — store buyers, brand owners, investors, and large retail chains — and each needed something different from the same product. The data behind the platform was excellent, but the design made it feel unfinished. During sales demos it didn't look as good as the competition.
There was also a technical problem underneath: two separate design libraries had built up over time, causing inconsistencies and slowing the engineering team down.
Research ran continuously throughout the engagement rather than in distinct phases. We worked directly with users in sales demos, product calls, and feedback sessions. Key personas (consultants, retail buyers, brand scouts, VC analysts) were refined over time as the platform evolved. We benchmarked against Harmonic.ai, Stackline, and Linear to calibrate visual quality standards. Feature work was validated in lightweight prototypes and usability sessions before engineering picked it up.

For every feature, we followed the same steps: understand the problem, map out the user flow, design it in Figma, check it side-by-side against the best tools in the market, then hand it to engineering with full specs. We did this on repeat for two years — on individual features and two complete platform rebuilds.




Design was never just a service function here. We were involved in strategy, roadmap decisions, and growth planning throughout. The product is better because of that — not just better looking, but built around clearer decisions about what to build and why.









The platform now works for all four user types with one consistent design. We rebuilt it from scratch twice as the product evolved. The design system we built gave the engineering team one shared set of building blocks, which meant fewer bugs and faster shipping. The product went from looking like a prototype to holding its own against direct competitors in sales demos.
Over two years: led two complete redesigns of the full platform across all user types (retailer, vendor, VC, enterprise retailer). Managed an in-house designer. Built the design system from scratch. Designed marketing sites and supporting materials. Contributed to product strategy, roadmapping, feature prioritisation, and growth opportunity identification. Notable features designed include: Presenting (AI-generated shareable category reports), Client Confidence UI overhaul (unified component libraries, visual hierarchy, data completeness), monitoring and brand tracking, visual vetting workflow, bulk upload, AI search brand card updates, retailer finder redesign, guest user flows, and mobile screens.
Reviews
★★★★★
I had the pleasure of working with Gytis for a long time, and he has consistently been one of the most thoughtful and dependable product designers I’ve worked with.
Gytis thinks deeply about the product, the user, and the business context behind every design decision. He is very strong at turning ambiguous ideas into clear, polished, usable experiences, and he brings a high level of taste and discipline to the work.
Gytis is someone I could trust with important product problems. He communicates clearly, takes feedback well, and has a calm, mature way of moving projects forward even when the direction is still evolving. That combination of creativity, judgment, and ownership made him a real partner to the product team!
