Find engineers at SaaS companies in Toronto

Toronto has long been a hub for SaaS, and the list above ranks the largest SaaS companies headquartered there by current headcount, drawn from public LinkedIn and Crunchbase records. With 1,239 matching companies in Refolk’s index, this is a good map of where the SaaS talent in Toronto lives - useful whether you’re recruiting, partnering, or sizing a market.

The biggest SaaS companies in Toronto tend to be the gravitational centres for specialised talent - senior engineers, ML researchers, applied scientists, designers - while the smaller ones compete on speed, equity, and proximity to founders.

Refolk converts this list into a live search. Ask for “SaaS engineers in Toronto hiring senior staff” or “founders of SaaS companies in Toronto who left in the last 12 months” and Refolk returns a ranked shortlist with the evidence that earned each person a spot.
