Y Combinator · Launch Video Breakdown: Hook, Pacing & Motion Design

.@ApolloAtomics builds the most compact nuclear reactors with the highest uptime and a deployment time of less than 24 months. Apollo took the pressurized water reactor technology that already powers 80% of the world’s nuclear plants and flipped one part, the steam generator, to make the plant an order of magnitude smaller without compromising power. Congrats on the launch, @AssilHalimi & Drew!

  1. The Hook

    The Nuclear Energy Problem & Apollo's Compact Solution

    “In this piece of nuclear fuel, there's enough energy to power a city the size of Seattle for a year. But it costs 20 billion dollars and 10 years to build a nuclear plant. It turns out it's possible to do that in a plant that's 80% smaller, costs 80% less, and takes 80% less time to build. We took the pressurized water reactor technology that already powers 80% of the world's nuclear plants and flipped one part, the steam generator, to make the plant an order of magnitude smaller without compromising power.”

    Motion
    Rapid cuts, 3D model fly-throughs, data visualization overlays, glitch text effects, and scale comparisons.
  2. Product Reveal

    Apollo's Proprietary Technology & Deployment Timeline

    “Our steam generator is the size of a shipping container. It's built in a factory, shipped to site, and installed in less than 24 months. Our technology is proprietary, patent pending, and uses existing regulatory pathways. We're building a megawatt demo in 2027 that will validate the technology and then in 2028, we're building a 100 megawatt plant to directly power a data center. We're Apollo Atomics, and we're building the future of energy.”

  3. Feature Teaser

    Broader Impact: Powering Cities & American Dominance

    “A single plant can power a city the size of Seattle. We're building the most compact nuclear reactors with the highest uptime and a deployment time of less than 24 months. We're bringing American dominance back to energy. The US invented nuclear energy. We need to mass-manufacture it to clean up the grid and power AI. We're Apollo Atomics. Let's build it.”
