. @speedrun Demo Day was a movie. Founders crushed it, the team crushed it, the vibes were immaculate.

Feeling proud and tired and happy, but more importantly grateful to get to work alongside the best team in the biz.

@jad_tarifi RSI will happen at all levels of the layer cake, but the strongest compounding will be at the model/weights layer!

@a16z @zynga I literally 3 min ago asked codex to use this framework for a project I’m working on!

[Josh Lu @JoshLu]

listen to @fabserafini! unlocking computer use at scale/reliability/efficiency is one of the biggest opportunities to create a huge human agency company.

@bhalla_arnavk turns out simulations are not all you need to get robots deployed IRL. excited for what y'all are building!

[Yusan Lin @yusan_lin]

AI slop isn't just tacky and uninspired. It can get you sued.

Generating fake AI faces that resemble real people, or using someone's likeness without permission, is creating new legal and reputational risks for brands.

So we built @mirrormirror_ai as part of a16z @speedrun, a marketplace where brands can digitally book real models and creators to generate AI content using their likeness, with their permission.

Brands browse and book identity-verified talent, agree on usage rights, and generate content within those terms. Every approved image comes with a signed license and embedded provenance.

We're seeing brands produce lookbooks and campaign visuals up to 10x faster, with up to 90% cost savings. Meanwhile, models and creators can earn additional income from their digital likeness without having to show up for another shoot.

Everyone is racing to make AI generation faster, cheaper, and more realistic. But there's still a huge missing piece: how do you license the rights to the people appearing in AI-generated content at scale?

That's why I'm excited about what we're building. Not just another AI generator, but the licensing and rights infrastructure for AI-generated content.

Despite having experienced every cohort so far, it always surprises me just how much a driven, ambitious team can get done in 12 weeks.

I've seen companies go from a standing start to putting a real dent in the world. I've seen teams multiply in size, gobbling S tier people along the way and turning their company into a gravity well for talent. I've seen revenue/usage/DAU go parabolic

SR008 applications are officially open. Show us what you'll be able to do in 12 weeks. It's time to apply (link below)
