UI/UX design agency for products that have outgrown their first interface

Your product works. But the interface still feels improvised, the user journey is harder than it needs to be, and every new feature makes the experience less coherent. heartbeat helps product teams turn that friction into a clear UX direction and a system their team can keep building on.

UI/UX work that connects product, brand, and growth

Good UI/UX is not decoration after the product is built. It is how users understand what the product does, where they are going next, and why they should trust it.

We work with teams when the product has become more capable than the experience around it. The goal is not a layer of polish. It is a product system that makes the next stage easier to use, explain, and extend.

A growing startup raised investment, outgrew its name, and needed a brand that matched where it was headed. We handled the full rebrand - from visual identity to website and brand guidelines for their team.

We developed motion principles, refined flows, and built the bridge between brand and product — expanding their identity and creating a complete product branch for what didn’t yet exist.

The goal: relaunch fast with a new brand and keep evolving from there. We handled everything inhouse - from brand and UI to motion and build.

What UI/UX design work can include

A better interface is not just cleaner screens. It is a clearer way for users to move through the product, understand what matters, and complete the work they came to do.

The scope starts where the experience is breaking down. Sometimes that means redesigning a core workflow. Sometimes it means creating stronger product patterns for a growing team. Sometimes the website and product need to tell the same story for the first time.

Product UX and workflow design. Core journeys, onboarding, dashboards, states, edge cases, and the decisions users need to make.
Information architecture and navigation. A clearer structure for features, content, and product complexity as the company grows.
Product UI and motion. Interface patterns and motion principles that make the product feel coherent, not assembled feature by feature.
Design systems and team guidance. Components, patterns, tokens, and practical direction that help internal teams make more consistent decisions.
Website and product-story alignment. A website that explains the same value users experience once they enter the product.

The strongest work connects product, brand, and website direction. Users should not have to understand three different versions of the same company.

Not our words - theirs

A clear first scope. Room to grow.

We agree on the work your product needs now. Further brand work or monthly support can follow if useful, with a separate scope and fee.

1 /

The first sprint

A month or longer / from $35K

Before work begins, we agree on a fixed scope and price around the product experience that needs attention. The work can focus on a core workflow, interface patterns, or the connection between product and brand. We do not bill by the hour.

2 /

Extend the foundation

Optional / scoped separately

If the work reveals a wider brand or website need, we can agree on a next phase. Starting with the product does not commit you to a full rebrand.

3 /

Keep building together

Optional monthly support

We can work alongside your team on new features and the materials around the product. We agree on the work and monthly fee separately. No hourly billing.
