Frequently asked questions

Got questions? We have you covered, if you have more please feel free to reach out.

What is the Impact Stack?

The Impact Stack is our performance-focused service offering for digital product design. It combines Research, Product Design Strategy, and UX and UI into a set of proven accelerators that plug directly into your roadmap. The goal is simple: improve conversions, strengthen retention, and turn design decisions into measurable business outcomes.

How is this different from hiring a UX/UI designer?

The Impact Stack treats design as a growth engine. Every activity is backed by research, strategy, and data, not just visuals, so your product achieves higher adoption, stronger retention, and real business performance instead of just looking good

Who is the Impact Stack for?

The Impact Stack is designed for product owners, founders, and tech teams in fintech, e-commerce, insurance, and beyond. It’s for businesses that want engaged users, confident releases, and digital products that scale without losing quality.

Can you work alongside my existing product team?

Yes. We don’t replace teams, we partner with them. Our process integrates into your workflow, providing strategic direction, accelerating delivery, and reducing risk without disrupting your workflow.

How does AI fit into Impact Stack?

We use AI as an enabler in our process, not as a feature of your product. It speeds up research, automates repetitive tasks, and streamlines delivery, helping us focus on high-impact UX and product design strategy.

How do I know where to start?

You can start with our Digital Impact Score quiz. In three minutes you’ll see how your product stacks up, where your biggest opportunities lie, and which quick wins you can unlock. From there, we’ll map the right path forward together.
