How many Pittsburgh companies valued at $100M or more were backed by local investors?

Based on PitchBook data for all Pittsburgh-based, venture-backed companies with deal dates from 2009 forward and minimum post-valuation of $100,000,000.

This table uses $100M as the cutoff because many Pittsburgh funds are pretty small ($10–$50M), so what a fund-returner investment looks like for them is different than a coastal VC who might have $200M+ under management.
