Restream.

In the early days of live video, a creator had to choose. Stream to YouTube, or to Facebook, or to Twitch - but not all three at once, and certainly not without a rack of encoders and a working knowledge of streaming keys. In 2015, two engineers in Vinnytsia, Ukraine, decided that choice was a bug, not a feature. Alexander Khuda and Andrew Surzhynskyi built Restream to take one video feed and push it, simultaneously, to every platform an audience might be watching.

A decade later, that idea has an audience of its own. Restream now serves more than five million registered users, from solo podcasters going live for a few hundred viewers to organizations broadcasting to the world. The company relocated its headquarters to Austin, Texas after a $50 million Series A in 2020, but it kept its engineering roots and offices spread across several countries. The premise never changed: going live should mean being seen and heard on every channel at once, without the friction that used to make live video the province of specialists.

That one-line description undersells what the product has become. Restream started as a relay - a way to fan out a single stream - and grew into a full production toolkit that lives in a browser tab. Today it handles the broadcast, the guests, the overlays, the comments from every platform, and, increasingly, the editing that happens after the stream ends. What began as plumbing turned into a studio.

Attention is scattered. A single audience might live half on YouTube, part on LinkedIn, some on Twitch, and a growing slice on TikTok. Before multistreaming, reaching all of them meant going live several times, or picking a favorite and leaving the rest behind. Restream collapses that into one broadcast: you connect your destinations once, hit go, and the same feed lands on all of them at the same time.

The second problem is conversation. When you stream to ten places, you get ten comment sections. Restream aggregates them into a single inbox so a host can read - and reply to - the whole audience without tabbing between windows, and can even overlay those comments on the broadcast itself. It is a small feature that solves a genuinely annoying problem, which is often the most durable kind.

Who uses it: individual creators and podcasters, small businesses running webinars and product launches, marketing teams, nonprofits, houses of worship, and large organizations. The range is wide precisely because the free tier lets anyone multistream to two platforms, forever - and the paid tiers scale up from there.

Restream's expertise is the hard, unglamorous engineering of live video at scale: ingesting a feed once and re-encoding it out to dozens of platforms, each with its own quirks, keys, and rate limits, in real time, without dropping frames. That reliability is the product. A broadcast that stutters or drops is worse than no broadcast at all.

The team is deliberately international - roughly 22 nationalities across offices that have included Austin, Tallinn, Kyiv, and Cascais. Its Ukrainian engineering roots run deep, and the company continued shipping through significant disruption. Distributed work here is not a perk bolted on after the fact; it is the operating model the company was built around.
