Video testimonial from Eric Fan, Founder and CEO, Lumos.
Refract Group2026
We design software that runs the daily work of a business, and build the design systems behind it.
Our operations software work is Keeyu, which helps large retailers manage everything that can go wrong after an order is placed, across multiple brands, sales channels and integrations. We designed the product from inside Keeyu’s team and built its design system in code. Our studio is in Sydney, Australia, and we work between Sydney and New York.
- Setup feels fragmented, and customers can’t tell what to do next.For Keeyu, which helps large retailers manage everything that can go wrong after an order is placed, we designed the product from inside the team and built its design system in code.
- Four kinds of user work in the same product.For Managed, a property platform that puts renters, owners, agencies and tradespeople in one place, we designed the product and built its design system in code.
- The tool is dense, and each screen works its own way.For Lumos, a platform for planning and booking out-of-home media, we went through the product screen by screen, designed the planning surface and built its design system in code.
What we think
Where we stand on software with a lot of moving parts.
Calling all three “Connected” hides the distinction between a successful login and a usable integration.
Entering credentials, checking permissions and importing records are different states. The interface should show which of those states the system is in.
Follow the main path and then the likely interruptions.
Missing data, a validation error, an expired session, a return visit. Check whether the product explains what happened and how to recover.
Use safe test data that keeps the complexity of real work.
Long names, old records, multiple teams and incomplete information. Each account state lets you examine something the others hide.
Reusing a component without agreeing its behaviours can reproduce the same ambiguity across a product.
Compare what they mean. Does saving close the panel or keep it open? Where does validation appear?
Start with a product sprint.
One problem, a fixed length, and a working prototype in front of your users at the end. If it’s worth building, you’ll know. If it isn’t, you’ll know that cheaper.
- One product or flow
- Fixed length
- Price agreed upfront
Audit
An audit of the product or flow as it is
Prototype
A clickable prototype of the fix
Test
What your users did with it, in their words
Plan
A build plan and estimate, yours to keep
In their words.
Questions
Yes. Refract designed the product for Keeyu, which helps large retailers manage everything that can go wrong after an order is placed. Keeyu had raised its pre-seed round when we started. We worked inside its product and engineering team, designed the product and built its design system in code, and Keeyu’s engineers built the product. Our studio is in Sydney, Australia.
Yes. Refract is a studio in Sydney, Australia, and our operations software project is Keeyu. Its product handles multiple brands, sales channels, integrations and operational workflows, often all at once, and we designed it and built its design system in code. Product design starts from $10,000 a month.
Yes. Keeyu’s product covers the work after an order is placed, and Refract designed it from the real product. We looked for the patterns shared across its workflows: how progress is shown, how related information is grouped, how guidance appears and how people move between tasks without losing context. That gave Keeyu’s team shared building blocks to extend as new parts of the product took shape.
Yes. At Keeyu, Refract was embedded in the product team. We began in their staging environment, worked in weekly sessions with their product and engineering team, and reviewed decisions in staging with the engineers building the product. An embedded team costs $10,000 to $30,000 a month.
Refract brings each kind of user into the work. Managed, a property platform, puts renters, owners, agencies and tradespeople in one place, and we designed its product and built its design system in code. On Lumos, a platform for planning and booking out-of-home media, we spent time with planners, traders, engineers and the people fielding client questions, who helped us work out why the product behaved the way it did.
Yes. If you want to try working with Refract before a larger scope, there is one week of work for $2,500, credited in full against work that starts within 60 days. Product design starts from $10,000 a month.
A closer look at the work
- Designing complex SaaS workflows: lessons from KeeyuHow relationships, progress and contextual guidance shape a usable product, and how to apply those lessons to your next difficult workflow.
- How to run a UX audit that leads to useful fixesA UX audit follows real tasks through your product, records where people get stuck and ranks fixes by user impact, evidence and the effort required.
- Prototype vs MVP: what should you build first?A prototype tests a question. An MVP is a usable first product. Choose the next build by the uncertainty you need to resolve and what real use requires.
