The problem: a 31-page manual

Sapling Energy reaches homeowners through direct mail. Before we started working together, every step of their campaign pipeline was manual — hiring freelancers for map analysis, contractors for satellite image review, staff for data cleanup, and someone to coordinate the mailing schedule.

The whole process was documented in a 31-page instruction manual. One campaign took 30+ days and $3,000+. Errors were common. And the only way to grow was to hire more people to do the same manual work.

What we built: 7 tools, from AI to automation

We replaced each manual step with a purpose-built tool — some powered by AI, others by smart automation and data engineering. Click through to see the before and after for each one.

BeforeManual Review

Hired contractors to manually review satellite images of homes, classifying roof type, condition, shading, and energy savings potential one property at a time. Slow, inconsistent, and expensive at scale.
