About R11

Software for the people building the grid.

R11 is a Chicago software company with one job: give residential solar contractors a true picture of their own work. Thousands of local crews build the grid, and almost every one runs on a stack that cannot answer where a job actually is, because the answer is split across a spreadsheet, an inbox, a group text, and a folder nobody can find twice.

So we built the operating system for that work: every installation on one record, from the signed contract through utility approval, with the office’s daily work and each financier’s reported funding attached to it. We are institutionally backed, and we would rather earn a smaller group of contractors who trust us than advertise our way to a bigger one.

Who you’d be working with

Real names, real faces. We came up in residential solar and in finance, and we have all worked a job whose true status nobody could find.
