Flick

End-to-end AI filmmaking software.

Flick is an AI filmmaking software that lets people create Hollywood-level short films completely using AI end-to-end. There are many AI tools that can give you 8-second casual clips to post on social media, but when it comes to creating truly high-quality films with coherent storylines, consistent characters, and cinematic aesthetics, they don’t come close due to their lack of flexibility, creative control, and fragmented creative flow. Founded by an award-winning filmmaker and a founding engineer at Instagram, Flick defines an interface specifically designed for native AI filmmaking that feels natural and enables end-to-end creative flows. Think of Flick as Figma for AI filmmaking. There are 4 complete AI short films created using Flick that got 20+ awards in international film festivals already and our early creator residency community are generating several AI short films every week. We are also building a community where we produce our own AI films as well as collaborating with other well-known filmmakers to share their “behind-the-scenes” workflows as resuable templates to inspire users in our community. We not only build product, we also build world-class content. The whole film industry will be revolutionized by AI and our goal is to be “the product” that defines this category.

An app that takes your money if you don't complete your habits.

Say what you're going to do, when you're going to do it, and how much money you'll forfeit if you don't do it. Send photo or timelapse evidence of you completing the habit by the time you set, or we take your money. Eg, I could set it to go to the gym (or meditate for 30 mins, or take a photo of a sent email, or of a max amount of calories on MyFitnessPal) tomorrow at 6am, or lose $30. If I don't send photo evidence in the gym (that we manually approve), I lose $30.

Foundry logo

Foundry

Infrastructure to ship real apps with AI - end-to-end in the browser

We’re building browser-native infrastructure that makes software creation production-ready end-to-end. Today’s AI tools can scaffold code, but they fail on the critical workflows that actually get products into production — provisioning, auth, QA, and compliance — all of which happen inside the browser. Our system makes these workflows deterministic, reproducible, and automatable, so both agents and humans can go from idea to a production-ready app. The opportunity is massive: billions of dollars of value locked up in workflows that today block non-technical founders and slow technical teams. We’re building the infrastructure layer that makes production possible.

Framebase

API for video.

Framebase is programmatic video. Writing applications which use video in a meaningful way is extremely difficult. And then there's the maintenance. Framebase makes video a first-class object. Instead of hiring a team to deal with transcoding configurations, device compatibility bugs, or CDN contracts, Framebase lets you add two lines of code to start treating videos as class instances. Framebase is a pivot of TapIn.tv, which is a Y Combinator S 2012 company.

Friday logo

Friday

The AI Email Client

Email sucks. It takes forever to go through, and hiring an assistant is costly and invasive. Friday is building the assistant that learns how to predict the action that you will take on your emails, and does it for you. Today's email products try to help you go through your emails a little faster, but if you have to get through 1000 emails, those products doesn't do much for you. The reality is, most of the emails you get don't require you to personally look at them. Friday completely eliminates the need to check those emails, and handles them all at once for you, immediately. Friday is here to file away spam, sift through newsletters for important tidbits, text you important notifications, and reply to mundane emails, so that no matter how many thousands of emails are in your inbox, you'll just be left with the few emails that actually require your personal touch. Getting this right is difficult, so everyone else settles with trying to help you go through your email twice as fast. If you want to go 100x as fast, you shouldn't spend even a second on useless emails. Friday gets this right, bringing the elite experience of having a professional assistant to the entire world.
