Ask HN: What are some cool or underrated tech companies based in Canada?

89•pedrodelfino•7mo ago
I'm based in Canada and curious to learn more about interesting or up-and-coming tech companies here — not just the usual big names like Shopify or Lightspeed, but also smaller startups, bootstrapped companies, or niche players doing great work in software, hardware, AI, sustainability, fintech, etc.

Here are some worthy ones I know of in Vancouver:

AbCellera (biotech)

General Fusion (fusion energy)

Rapidia (metal 3D printing)

Human in Motion Robotics (exoskeletons)

Grin Technologies (ebike components)

Arca climate technologies (atmospheric CO2 removal via mine tailings)

One to stay away from is Mattermost
abuani•7mo ago
Why is that? I feel like every other go security vulnerability was reported by a security researcher there, so I assumed they have a decent engineering culture.
holyroller•7mo ago
You're right they are one of the largest Go-based applications and get asked to test go releases.

My opinion is they have a poor engineering culture though and worse leadership that is abandoning open-source roots, chasing "mission critical" government/enterprise business.

Sparx - they make a great high tech home skate sharpener. Me and just about every serious player I know own one:

https://sparxhockey.com/

burningChrome•7mo ago
These are insanely popular in the US too. And I can verify that most of the guys I play with own one. They say their kids teams travel with four or five so the kids get their skates tuned before every game.

That product was an absolute game changer.

I work at https://spare.com/

We make tools for transit agencies to manage paratransit and microtransit services, mainly for people with disabilities but also for campuses and low-density areas. Managing these types of services is a real, hard problem with billions spent every year.

Our customers include Winnipeg, Oakville, St John, Saskatoon, and Powell River (also Dallas, LA, Austin, more in Japan and Europe), with more coming soon - including driverless vehicles with routing and scheduling powered by us.

We're Vancouver-based, and we're hiring :)

I make https://voicecast.app/ and I’m based in Toronto :P

toomuchtodo•7mo ago
Voicecast looks awesome. Are you considering a video version?

Thanks for commenting, would’ve never found your product otherwise.

mattbettinson•7mo ago
As in sending video messages? That would be intriguing! I’d never considered it.

No problem! Are you a podcaster?

toomuchtodo•7mo ago
Content creator/artist of sorts, interested in engaging with folks in new ways. Your comment was a bit of an aha moment.
mattbettinson•7mo ago
Well, I will be definitely building a video feature, it’s a great suggestion. Let me know if you end up using Voicecast, or have any ideas on how to get the word out!
mattbettinson•6mo ago
Just wanted to say - I've added video messaging to Voicecast after being inspired by your suggestion!
toomuchtodo•6mo ago
Thank you! Besides subscribing, I’m happy to send some fiat you way for the time. Let me know how I can do that.

We are building some exciting cloud deployment tools at https://defang.io.

We are making it super easy to manage your deployments through the compose.yaml file you probably already have. The idea is to have a single definition of your application, that you can use locally, and project it into any cloud.

We're a small team based in Vancouver. If you're in town, reach out and come visit: jordan.stephens@defang.io
