Capabilities

Your org needs what it doesn’t have. Bring us in when you need senior design, research, and product capability: as a leader, or as a team.

I’m Gagan Diesh. For 25 years orgs have brought DesignStamp in to be the capability they didn’t have in-house. For some that was a research wing, and we ran global research for PEPFAR, the world’s largest HIV/AIDS initiative, along with work for Johns Hopkins, the OECD, and the Gates Foundation. For others it was a design team, and we designed Central 1’s first mobile banking app, now running at 300+ financial institutions. For others it was someone to run the whole thing.

That’s what happened at Rouxbe: DesignStamp was hired as agency of choice when it was a startup, and I became employee number 3, building their entire dev and design team and managing all design and strategic partnerships. Rouxbe is now a global leader in culinary education, from home kitchens to military bases. I was also Thinkific’s first VP of Design and Research, where I grew the design org from 6 people to over 30 and hired most of them. We worked hard to successfully complete an IPO and achieve a $1 billion valuation.

Are your design and research functions keeping up? Do you have the right people and leaders to build what your customers are asking for? If not, that’s worth a conversation. Whether you need someone to lead your team or extra hands to get through the next two quarters, we’ll work out what’s missing and fix it together.

As a leader

Fractional design and product leadership

For companies with designers and nobody senior running them.
Embedded with your team: org design, hiring, operating rhythm, critique standards, and roadmap partnership with your exec team.

This works when

  • You have 3 to 15 designers and nobody senior running them.
  • Your design leader has either left or is strapped for time and you can’t afford more F/T leadership.
  • Your team is not able to keep up with the speed of what is needed to take your product to the next level.

What it looks like in practice
At Think Tank Training Centre, Canada’s top-ranked CG and VFX school, I covered a one-year parental leave as fractional Head of Product and Design. We rebuilt six admin workflows and recovered 1.5 full-time roles per term.

Before that
Director, then Senior Director, then VP of Experience Design and Research at Thinkific. I scaled the design org from 6 to over 30, built the research function from zero, and we took the company public at a $1B+ valuation.

On AI
I build AI products myself, in code, including the coaching platform my own business runs on. So I can tell your team which parts of their workflow AI is ready for and which parts it isn’t, and set the rules for who reviews what. Most teams have tried a tool, seen it produce less than mediocre results, and quietly stopped.

How it works
Usually two days a week, three months minimum. We start with a call about what’s actually going on. I come back with what I think it needs and what it costs, including the times that’s less than you were expecting.

As a team

Team augmentation

Senior designers, researchers, and product people, working inside your team.
I work out which roles the problem actually needs, find the people, and stay involved while they get up to speed. You get a team picked for the job, all working to complete a specific project, within a specific timeline. Speed is a natural byproduct of this type of engagement.

This works when

  • You have a bunch of opinions on why your customer is unhappy and no researchers.
  • Your roadmap has outrun your design capacity and hiring won’t close the gap in time.
  • A project needs senior people who can walk in and be useful in week one.
  • You need the capability for two quarters, not two years.

As a research wing
I led global research for PEPFAR, the world’s largest HIV/AIDS initiative, running 150+ participant studies across multiple countries to guide product direction for care providers and programme administrators. Similar work for Johns Hopkins, the OECD, and the Gates Foundation.

As a design team
We designed Central 1’s first mobile banking app, then every major release across iOS and Android. It now serves 300+ financial institutions and ranked first for mobile banking in North America.

Recently
A six-month usability research engagement for Unosquare in 2025: 50+ interviews across four countries with AI-assisted synthesis, ending in a stakeholder workshop that turned the sharpest pain points into redesign priorities for their client’s global platform.

About DesignStamp

Design and product leadership. Twenty-five years of it, most of it hands-on.

DesignStamp has been my practice since 2001. For eighteen years I ran it as a consultancy, leading global research for PEPFAR, the world’s largest HIV/AIDS initiative, and designing the mobile banking platform now running at 300+ financial institutions. Clients included the Gates Foundation, the OECD, and the U.S. government.

In 2019 I put the practice down and went in-house at Thinkific, moving from Director to Senior Director to VP of Experience Design and Research. I scaled the design org from 6 to over 30, built the research function from zero, and we took the company public at a $1B+ valuation. I came back to DesignStamp in 2023.

Since 2023 I’ve done both. Fractional design and product leadership for companies scaling their teams, and workshops for product orgs working out what AI actually changes. I build AI products myself, in code, so that second part isn’t theoretical.

Today we focus on

  • Team augmentation. Senior designers, researchers, and product people embedded with yours, for as long as the work needs.
  • Fractional design and product leadership. Someone to run the function while you build toward the permanent hire, or instead of it.

I take on a small number of engagements at a time. I have also worked hard to build a network of senior professionals who I can call upon to help when needed. So let’s have a conversation, and figure out what you need so I can help shape the right approach for your situation.

Our Principles

We respect our clients

We listen closely, learn deeply, and partner with clients to understand their goals. We ensure our work aligns with what matters most to them and demonstrate domain expertise they can rely on. Success is measured by the outcomes that matter to their business.

We respect our work

We hold ourselves to a high bar. We share our process, speak plainly, and stand behind the integrity of what we create. We believe great design is collaborative, intentional, and clear.

We respect ourselves

We value diverse perspectives and we work well inside existing teams. Whether we’re leading the design org or supporting it, we’re here to help each other do our best work. ❤️

Our Process

1.Understand your context

We begin by learning your team’s goals, constraints, culture, and the decisions in front of you. This gives us the clarity needed to support you effectively.

2.Align on the real problem

We surface assumptions, map the issues, and confirm what success looks like. This alignment prevents wasted effort and establishes a shared direction.

3. Design the right engagement

Based on what you need, that might be fractional design leadership, embedded product and UX support, an AI workshop, or a focused research engagement. Every approach is tailored and intentionally scoped.

4. Build momentum quickly

We work in short, focused cycles with clear communication, practical deliverables, and visible progress. You get insight, alignment, and decisions that move your team forward.

5. Strengthen long-term capability

Our goal is not dependency. We leave teams and leaders with clearer processes, stronger decision-making habits, and the confidence to move independently.
