Goji Labs

We Define the Right Build Before We Start It.

A redesign. A rebuild. A new feature. The request you start with rarely tells the whole story. Goji Labs helps enterprise teams determine what the product needs before they commit significant time and budget to building it. We clarify the business outcome, examine what is standing in the way, and define the right response. Our clients are established organizations, including publicly traded and PE-backed companies. They come to us to: 1. Extend or accelerate a product that already works 2. Diagnose and revamp one that doesn't 3. Decide whether a new product opportunity justifies the investment Every engagement starts with a fixed-fee Strategy Sprint. Most run two weeks. You leave with a clear recommendation: what to do, why it matters, what success should look like, and what it will take to deliver. That recommendation becomes the brief for design and engineering. We test it with you before anything gets built. Then we build toward the outcome you agreed on. Selected results: -TGS: 405% increase in revenue-generating traffic. -Insurance: 38% lift in quote-to-policy conversion. -Mitsubishi's AnyMile: 35% reduction in route planning time. AnyMile went on to win Best of CES 2023. Goji Labs is headquartered in Los Angeles, with an office in New York.
