Benchmark Gensuite · Modernisation
A modern suite that keeps customers' habits
Specialists run environment, health and safety work on Benchmark Gensuite every day, and they have built fast habits on its interface. We made coded prototypes of shared interface patterns and a three-view scope selector, so Benchmark could judge each modern choice against those habits before wider release.

Omny AI · AI trust
Suggestions people check before they accept
Each AI suggestion now waits for a person's choice before it reaches the listing, and colour shows what the AI wrote and what a person added. Omny AI was acquired by Primelis.

ConnectX · AI product
Ask a question, get the right energy dashboard
Facilities operators, finance leads and sustainability teams ask ConnectX a question in plain words, and it builds the dashboard each of them needs.

Eden AI · Developer platform
Three ways to start a workflow, one search box
Developers can start from a template, from the AI or from a blank canvas. We brought all three into one search box that recognises which they mean.

Phoenix · FinTech
Two trade models, prototyped for testing
Working within an on-chain exchange's design team, we made both competing trade models as complete clickable prototypes, to the same depth, so testing would compare the models rather than the finish. Then came a design system its engineers could build from.

What clients say
“Their research changed how we thought about scheduling across companies. The MVP was clearer because of it, and so was our roadmap.”
Stephanie LeueDoodle“We didn't want another AI chat window. Tcules designed a dashboard where you ask a question and the digital twin of your building answers, with the right data and assets in view. They proved it in a working demo, then made it production-ready.”
Pratik GhoshalCEO, ConnectX
“For three years Tcules has designed every one of our products. They work like part of our product team, improving them continuously and helping us shape AI features our customers can check and trust.”
Clément ContamineCPO, Primelis“Eden AI gives developers one way into hundreds of AI models, so the product has to be easy to find your way around. Tcules understood that quickly. Our developers had specs they could build from, and our users told us they loved the new design without being asked.”
Samy MelaineFounder & CPTO, Eden AI
“Tcules started by asking our families and carers what got in their way, turned it into a clear product plan, then redesigned our web platform and both apps. Their developers built the frontend from those designs, so nothing got lost in the handover.”
Jody O'NeillCEO & Co-founder, CuramCare“It was simply the most successful long-distance 3rd party collaboration I have seen. The company is on eye-level or above for the services they offer. Their staff were really good.”

Three ways to work with us
Not sure which suits you?
Tell us about the product, and we'll suggest one.
How our designers use AI
AI does the routine checking, so more of your product gets examined. People make every decision.
1 · AI
Checks your live product, screen by screen, against its design system
2 · Designer
Decides which differences matter to your users
3 · Designer
Tries the fix in working code and signs it off
Thinking from our own projects
Tell us what you're building
An idea, a prototype or a product with years behind it. One line is enough to start.
Questions SaaS teams ask before hiring a product design studio
How do we start, and what does it cost?
Send a few lines and we'll reply to arrange a call. You can start small, with an audit or a pilot on one flow at a fixed price agreed up front. Defined projects are priced on their scope, and ongoing work has no minimum term.
Can you work with our own designers and engineers?
Yes. Our designers work inside your files, design system and review rhythm, so your team sees the work as it happens. Your engineers can build from our designs, or our developers can build alongside them.
Is Tcules a UI/UX design agency?
Tcules is a digital product design studio in Ahmedabad, India, founded in 2017. We do UI and UX design, visual design included, plus the research, product thinking and engineering around it, for SaaS and other ambitious software.
Do you only work with SaaS companies?
SaaS is our particular focus, and we also design business applications, data-rich interfaces, consumer products and AI products, at any stage from new idea to established platform.
Can Tcules design and build a SaaS product end to end?
Yes. Product Design shapes what the product does, Design Engineering takes it into code, and Software Development carries it through frontend, backend, integrations, testing and release. You choose where our part stops: designs for your engineers, a finished interface or launch-ready software.
Does Tcules design AI features people trust?
Yes. Through AI Product UX we design copilots, agents, AI search and the review steps people use to check and correct AI work. Recent examples include BuildTwin's workspace for reviewing AI quality checks and Eden AI's search, which makes clear whether people are searching or asking the AI.
