Background

We engaged Granite & Glass to lead a web development initiative supporting our consumer business.

The challenge

Our internal team was stretched and we needed senior expertise without adding permanent headcount. Prior vendors had underestimated the complexity of our stack and stakeholder map.

The work

Granite & Glass embedded a dedicated pod, ran weekly working sessions with our leadership, and shipped in tight two-week iterations. Documentation and stakeholder comms were part of the delivery, not an afterthought.

The outcome

We hit our launch window with room to spare. The team stayed on to support the first 90 days of operations, which made the handover completely painless.

Delivered 2.4× the pipeline of the previous vendor within two quarters.
