Every great story needs a main character.

Protagonist first invested in Tenstorrent in 2024 and has participated in every round since. George and Harry helped bring in the lead investor for our last round, along with several top strategic co-investors and customers. They work alongside us on go-to-market and financing strategy, and above all, they do the work rather than wait for others. They’ve earned their place on our cap table and in our boardroom.

Protagonist backed us in a meaningful way and helped transform the business. Harry has been hands-on with us practically every day — he was instrumental in rethinking our capital strategy, which has fundamentally changed how we scale. He’s a true partner, not just an investor.

Protagonist believed in Arago before anyone else — they pre-empted our first round before we’d even hit demo day. Since then, they’ve been true partners, helping us build our IP strategy from day one and supporting us through every fundraise since.

Protagonist is more than just an investor. They’re founders and operators who truly understand the entrepreneurial journey.

When we raised our Series A, there was a lot of interest. Choosing Protagonist was a no-brainer. Their network, their support, and their feedback have been invaluable. I recommend them to any founder.

Working with George and the entire team at Protagonist has been a game-changer for Unicorn. Their team doesn’t just invest; they actively partner with founders to help you win. They offer deep insights, operating experience, strategic guidance, and an unmatched network. They move fast, think big, and truly care about the long-term success of the companies they back. If you’re looking for investors who roll up their sleeves and have a “founders first” mentality, Protagonist is the real deal.

Protagonist bet big on Telly early, seeing our disruptive potential when others hesitated. They didn’t just invest—they partnered. With Protagonist, it’s more than a check—it’s hands-on support to help founders win.
