Ask HN: What are some tech cos in Vancouver, BC tackling interesting problems?

Please keep the discussion about real estate prices, how Microsoft's office here is an H-1B, "what does HootSuite offer that other companies don't?!", to a minimum. Believe me, I live here. I know. And just for the record, Microsoft's new office in Vancouver mostly hires Canadian citizens/PRs for permanent positions. An H-1B/L-1 holding tank to Redmond was the original plan, but when the temporary foreign worker scandal hit in 2014, the company backtracked on L-1 hires for the new Van office due to pressure from the federal government (source: MSFT recruiter via an anecdote in /r/cscareerquestions). I think London and Zurich are more popular for L-1 holding tanks than Vancouver these days.

I don't know if HN is this is the appropriate site to ask this question, but /r/cscareerquestions wasn't much help. And by the way, they can be bootstraped, have small-cap VC funding, have huge a16z/SoftBank/KPCB-scale VC investments; they can be startups, they can be more mature publicly-traded companies; they can be homegrown or big U.S. companies; it doesn't really matter. They should have a lot of smart people working on interesting problems in technology. What are some of them?

I also wonder which companies have signed up to the new WeWork space in Bentall III (https://www.wework.com/buildings/burrard-station--vancouver) that's opening "soon". As far as I know none of the tenants have been made public. Maybe they're under confidentiality agreements?
