PLANGRID

Tracy Young was a civil engineer at a construction firm and spent her days dealing with paper blueprints. They were heavy.

They got wet. They were always outdated because changes happened faster than new prints could be distributed.

One day she looked at her iPad and thought: why can’t I just view the blueprints here?

She co-founded PlanGrid in 2011 with Ralph Gootee, Antoine Hersen, and Kenny Stone. The original product was dead simple — upload construction blueprints, view them on a tablet, and mark them up with annotations.

That was it. But for construction workers, it was revolutionary.

SaaS subscription per project or per user. PlanGrid charged construction companies a monthly or annual fee for cloud-based blueprint storage, viewing, and collaboration.

Free tier for small projects, paid tiers for larger teams and features.

The product had inherent viral properties — when one person on a job site used PlanGrid, everyone else needed access to the same drawings.

Blueprint viewing and markup on mobile devices. Sheet versioning and automatic update distribution.

Field reports and daily logs. Punchlist management for tracking and resolving issues.

Photo documentation linked to blueprints. Integration with Autodesk BIM tools (post-acquisition).

Bottom-up adoption on job sites. Individual project managers and superintendents started using PlanGrid because it solved an immediate, obvious pain point.

It spread through construction companies as workers moved between projects. Y Combinator provided the initial network, and construction industry word-of-mouth did the rest.

Competing with Procore, which offered a broader construction management platform. PlanGrid was excellent at one thing (blueprint management) but struggled to expand into a full construction management suite.

Autodesk’s acquisition solved this problem by folding PlanGrid into a larger product ecosystem.

Sequoia Capital led the Series B. Earlier backers include Y Combinator, Tenaya Capital, and Founders Fund.

The company raised $69 million before being acquired by Autodesk for $875 million in 2018.
