Every child in the world will grow up with Mickey Mouse and Padlet. That's our vision. We are making the default way of collecting and sharing thoughts on the Internet. Our members love the software. We have over 50 million active users making Padlet one of the most used apps on the planet. Our goal is to be THE the most used app on the planet. We are venture backed AND profitable. We are 35 people (plus a baby crane that we've adopted but it doesn't really do much). That's 2 million active users per employee. Some really badass people work here.

Pinterest is the world's first visual discovery engine. People use Pinterest to discover ideas to try in their daily lives. More than 300 million people around the world use Pinterest to dream, plan and prepare for things they want to do in life. We always start by asking: whose problem are we solving? Is it significant? Are we making Pinners lives better? If products don't work for people they don't work for us. The success of Pinterest depends on the ownership of every Pinployee. We all own Pinterest and work to achieve results that benefit everyone, not just specific teams or individuals.

The architectures that power modern AI were designed for language, not for science. They were never built to understand DNA, interpret experiments, or learn the rules that govern living systems. Closing this gap represents one of the defining opportunities of our time. Our team has pioneered advances across frontier AI, including the first models trained with one-million-token context windows, and now scaling toward one billion. We focus on innovations on systems and architecture, because building AI for science demands a fundamentally different foundation. As a first application of this technology engine, we are advancing AI for life, the most complex and consequential domain of all. We are the AI team behind Evo and Evo 2, the generative genomics models used to create real gene-editing tools and the first whole genomes designed entirely by AI. That work demonstrated that AI can create biology, not just analyze it. We are now building multimodal models trained directly on the fabric of biology, enabling faster discovery, deeper understanding, and entirely new capabilities. As we push the frontier of scientific world models, we will build systems hand-in-hand to ensure global biological resilience: rapid detection, rapid response, and rapid countermeasures against emerging threats, both natural and synthetic. Our mission is ambitious: to reimagine what AI can do for science, and to build that future.
