What do you do when you have the technology but no product to show for it?

That was the challenge posed to my team. We were tasked with creating a demonstration for a cutting-edge ACH payment feature—similar to Cash App or Venmo—that could seamlessly integrate into a partner’s solutions. However, the problem was clear: we had the code, the tech, and the backend capabilities, but no tangible application or interface to showcase its value. With a new partnership with Visa Direct, the pressure was on!

To complicate matters, the project was highly ambiguous. Two teams — product and engineering — were unsure of how to proceed, and the only target in sight was a fast-approaching client pitch to a major insurance company in just four weeks.

This case study explores how I turned a vague starting point into a clear plan, united teams around a shared vision, and delivered a solution that exceeded expectations.

The ask was simple on the surface: “Sell the client on this feature.” But the execution wasn’t straightforward. We faced several challenges…

Ambiguity 

With no existing interface or product, we needed to craft something entirely from scratch.

Uncertainty Across Teams: 

Both the product and engineering teams were unsure how to position the feature for client meetings.

Time Constraints:

We had just four weeks to craft and validate a compelling demonstration.

CRAFTING A PLAN FROM SCRATCH

Recognizing the need to cut through the ambiguity, I took the lead in shaping a clear path forward. I organized a brainstorming session to bring all stakeholders together, which helped identify the feature’s core capabilities, potential applications and set expectations for the work ahead.

During this session, I proposed a bold but practical idea:

Build a faux consumer-facing application

Tailor this specifically to the insurance industry, the initial target for sales, to demonstrate real-world usability and value.

Create a compeling story for the client

The project highlights my ability to:

check

Navigate ambiguity: I turned a vague starting point into a clear, actionable plan.

check

Unite teams: By fostering collaboration and alignment, I ensured the success of cross-functional efforts.

check

Deliver results under pressure: Operating on a tight timeline, I delivered a solution that exceeded expectations and drove business impact.

By simplifying complex technical topics, keeping teams aligned, and creating a vision that resonated with the client, this project exemplifies my strengths as a product designer and strategist who thrives in ambiguous and fast-paced environments.
