Impress clients. Win deals.

Clickable demos that close

Build polished, interactive prototypes that show clients exactly what you'll build before you build it — and win the project before the SOW is signed.

How it works

From idea to tested prototype in four steps

A prototyping workflow designed for speed, real feedback, and confident decisions

Step 1

Understand the client brief

Describe the client's product, industry, and goals. Greta builds around their context, not a generic template.

Platform

Proposals that look like finished products.

Win more client projects by showing exactly what you mean.

Client-Grade Polish

Prototypes look and feel like finished products — clients can't tell the difference until you tell them.

Live Edits in Meetings

Make changes on the spot during client calls to show responsiveness and reduce revision cycles.

Faster Approval

Show instead of tell. Clients approve faster when they can click through what they're approving.

Scope Clarity

A clickable prototype eliminates scope misunderstandings before work begins — saving everyone time.

Design-to-Dev Handoff

Turn the approved prototype directly into your team's development blueprint.
