Avataros

We bring character to life. Authentic 3D avatars built for live interaction.

[Avataros @Avatar__OS]

Interactive and dynamic content powered by AI will be the next wave of new media.

Fully lifelike 3D avatars that are interactive, scale like software, and integrate anywhere, will change the very nature of our digital world.

Bringing characters to life is more than just lip sync
We're enabling LLMs to direct characters in real-time @ Avataros

We call the process TEA - Think, Emote, Act

Custom ML Trained lip sync is just the baseline. The character needs to know what its thinking and saying and translate that into how it emotes and acts.

Blink. Look at camera. Eye roll. Gesture. Sigh. Happy. Annoyed. Worried.

@UnrealEngine version lets you talk to any metahuman live

Anyone interested in a plugin version to use with their hashtag #Metahumans?

What if you didn't have to gamble on generative outputs?

What if characters were "Trained" to always be on brand? Even if they were... let's say - chased by a mythical beast through an underground world...

Sounds a lot like a game.
At @Avatar__OS we think it's a whole new medium.

2026 is shaping up to be the year of 3D Gen AI.

At @Avatar__OS we're asking: what if you didn't have to gamble on generative outputs?

Can't wait to share more of what we're working on.

"We believe that interactive and dynamic content will be the next wave of new media — and authentic characters will drive fan and audience engagement,” says @isaacbratzel, founder of new M13 portfolio company @Avatar__OS.

What if you could have an avatar that was more authentic? That not only looks like you, but moves and acts like you in three-dimensions? AvatarOS is building lifelike 3D avatars that are interactive, scale like software, and integrate anywhere—and they’re tapping into a global digital avatar market poised to reach $270.61 billion by 2030.

"We believe that unlocking volumetric capture and 4D is going to open up a whole new set of behaviors and engagement between artists, creators and their communities that we can't actually predict today," says M13 partner @latifperacha.

So A16Z GAMES @speedrun is in the books. It has been quite a ride for @Avatar__OS (story below) but since most won't read that far, huge shout out to our cohort lead @tkexpress11 for just being awesome, and @andrewchen and the whole @a16zGames team for a truly excellent program.

In August of last year we got accepted to Speedrun 2 in SF. My wife and I were expecting our 3rd child and we realized the little guy would be due to pop during the program. This was such an amazing opportunity that we moved heaven and earth to make it happen (shout out to the most amazing wife and mom in the world Meron Bratzel).

But as things go, the day before I was set to get on a plane to San Francisco, I got a call from my wife. She was at a check-up with her OB. We were still more than 5 weeks away from the due date but they were going to keep her at the hospital indefinitely.

I got to the hospital, spoke with my wife and the doctors, and then when I had a minute I called Troy and told him the situation. The A16Z Team got back to me nearly instantly and told me not to give it a second thought - come to Speedrun 3 instead.

Little RoRo was born just a few days later, and he and his Mama were both in perfect health. And it turned out Speedrun 3 was held in my own backyard of LA at the new A16Z office, making it much more convenient for us with a newborn.

Having this come full circle, with such an amazing response and result on all fronts is truly remarkable, and I'm so appreciative of everyone that has supported us along the way.

Be so good they can't ignore you!

I had an investor last year ask me (or rather tell me) - "you can't really think AvatarOS can compete with Epic Games and Metahuman on digital humans". (Never mind that I wasn't proposing to compete with Epic) Imagine what that investor is thinking now with the release of #sora and the avalanche of other AI video generation models...

First, lets give this investor a break. I'm sure my pseudo pitch was just a complete trainwreck. But, second, let's take this comment at face value for a second.

1. Yes, I absolutely do.

2. One of the great things about tech and VC is the ability to play positive sum games. These things are best built as multipliers of other great technology. Metahuman walked so we could run!

3. What do you think people told Tim Sweeney when he was building Epic Games???

4. Is the contention that all cool stuff has already been built, or is so complex that only OpenAI or Epic Games etc. are allowed to build it?

5. The very nature of big companies and their inherent incentive structures give startups and small focused teams an immense advantage, especially when it comes to new technology and especially during large disruptions.

Find the future that you want to see, then build it, and make it so awesome others can't help but see it too.

Here's a small peak behind the curtain - some progress towards procedurally analyzing, training, and generating authentic human avatars and authentic human motion that is three-dimensional, interactive, and interoperable, while maintaining the subtle nuance that makes individuals unique.

Shout out to @elevenlabs for the voice training.

A lot of cool stuff coming up - check us out at https://t.co/6uohxRNMhV and subscribe to receive updates!

I'll be at #GDC and #GTC later this month, reach out!
