Best High-End Professional Networking App

Upstream is, bar none, the best networking app since the early days of LinkedIn. Whether you’re an entry or mid-level employee, an investor, an exec, a gig worker or the founder or CEO of any company, there are great communities on Upstream for you. I participate in eight of them and just founded my own community. I meet great new colleagues at every online event I attend.

If you don’t join, you’re doing yourself a disservice.

The most helpful place online

Upstream is the most helpful place to be online, full stop. The platform has fostered an environment where communities are supported as accessible, inclusive spaces and the events are the best use of your time minute for minute than anywhere else I’ve seen.

No real point to this app

I joined this app excited to find a professional community but I honestly don’t get the point of the app.

It’s just a bunch of “rooms” you request access to and then people just ask for intros/advice. It’s like a Twitter for questions but most of the time people don’t respond. Why would I scroll through a bunch of strangers’ questions in my free time?

Bottomline there’s not a lot of community-building, it feels like it’s more of a transactional space. Only nice thing is that there are office hours but that’s about it.
