What marketplace teams receive from a design engagement at Halo Lab is a product designed for both sides simultaneously — buyer flows and seller flows with distinct information architectures, trust signals designed into every transaction step.
We design two-sided and multi-sided marketplace products with participant roles separated upfront — search and discovery, listing creation, messaging, transaction, and review flows designed as a system before any screen is handed to engineering.
3 main challenges holding back your growth
Outgrown identity
Your company has grown, but the brand no longer reflects scale or direction.

One UI for all users
Buyer and seller flows share the same UI — neither participant gets what they need.

Missing trust signals
Generic design fails to signal safety — users hesitate before committing to a transaction.

Search doesn’t convert
Listings are findable but not compelling — discovery ends before the transaction begins.
“All projects in which we’ve involved Halo Lab have been great successes, but their leadership on our brand refresh is worth highlighting.”
“We’ve had feedback from users, investors, and employees, and everyone has said that Halo Lab did a fantastic job with the branding.”
“We’re proud of their branding services. They not only do what we tell them but also make suggestions to help us improve our offerings.”

FAQ
Why invest in branding services?
Why invest in branding services?
What does marketplace UX/UI design include?
Buyer and seller interface design, trust signal systems, search and discovery UX, transaction flows, messaging, admin and moderation tools, a marketplace design system, and an engineering handoff.
Do you design for both buyers and sellers separately?
Yes. Buyer and seller interfaces are designed with separate information architectures — each participant gets a flow that matches their goals, not a single interface stretched to serve both sides.
How do you design trust into a marketplace?
Trust signals — verification badges, review systems, identity indicators, and transaction safety patterns — are mapped in the research phase and designed into every key moment before a commitment is made.
Do you design search and discovery?
Yes. Search UX, filter systems, sorting options, and category navigation are designed for findability and conversion — with relevance and result layout optimised for the specific marketplace type.
How long does marketplace design take?
Most marketplace design engagements take 10 to 18 weeks depending on the number of participant types, transaction complexity, and whether a full design system is in scope.
Do you design admin and moderation tools?
Yes. Platform admin interfaces — listing moderation, user management, dispute resolution, and analytics dashboards — are designed as part of the standard marketplace design engagement.
Do you design for mobile and web?
Yes. Most marketplaces require both — mobile-first for consumer-facing discovery and transaction flows, and web for seller dashboards and admin tools. Both are designed and specified in the same engagement.
Can you redesign an existing marketplace?
Yes. Marketplace redesigns are common — we audit the existing product against trust, conversion, and participant adoption friction points, then redesign with clear improvement goals before any visual work begins.
Can you also develop the marketplace product?
Yes. Full-stack platform development is available following design — one team handling design and engineering so the component architecture in Figma maps directly to the production codebase.
