Our story

Founded to Solve Problems

Pillar was founded in 2019 by a diverse group of individuals who understand how complex it is to be a residential contractor. We’ve spent the last three years building a platform that’s custom-tailored to contractors’ most common challenges — based on feedback from some of the most respected contractors in the industry. Our focus is, and always will be, to make Pillar feel as natural, useful and effective as your must-have tools in the field.

Our Values

Zero Downtime

Pillar is built using best-in-class infrastructure so we can ensure that it’s always ready to do its job.

We stand by Pillar like you stand by your homes. Contact us whenever you need our help.
