Harj was the first non-founder Partner hired at Y Combinator in 2010, helping scale the program from 30 to over 100 companies per cycle.

As a YC partner from 2010 to 2014, Harj worked with breakthrough companies like Zenefits and Instacart, and created interviewing systems still used by YC today. He returned to YC in 2020 after leading Triplebyte, which helped over 500 companies including Adobe, Uber, and Dropbox hire thousands of engineers.

Harj's companies and investments have transformed technical hiring and early-stage venture capital, with Triplebyte processing thousands of engineer placements and his YC portfolio companies achieving billions in valuation.
