FleetWorks is rebuilding the $1 trillion freight marketplace with AI. Every year, companies spend over a trillion dollars moving freight across the U.S. — but the system for matching trucks with jobs is still slow, manual, and fragmented. FleetWorks is fixing that. We’re turning today’s chaotic freight market into a modern, intelligent marketplace — one where AI agents replace the endless phone calls, texts and emails and match jobs to trucks instantly.
Fleetline is building the first complete-context algorithmic load planner for mid to large-sized trucking fleets. Today’s dispatchers face an overwhelming task: balancing regulations, customer demands, live fleet data, and individual driver needs, all while coordinating across siloed tools and teams. Mistakes run rampant, and each mistake is thousands of dollars. Even the select fleets using algorithms that have fleet-wide context struggle: the outputs are rigid, hard to interpret, and are blind to real-world nuances like driver preferences and schedule exceptions. Fleetline solves this by combining advanced optimization with LLMs that can easily adapt algorithms to each fleet’s needs and capture driver-specific information. The result is smarter planning truly optimized for every fleet and its drivers.
Fleetzero builds electric and hybrid propulsion systems for large ships and is developing unmanned cargo vessels.

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.

Floot lets non-coders & entrepreneurs build real web apps that actually work. We’re taking a new approach by building everything from the ground up for AI. ✨ Try building an app at floot.com Existing AI app builders fall short of enabling non-coders to build real, serious apps. They often: - Break down when building anything more than a prototype or toy app - Have non-coders stuck with errors they don’t understand - Require non-coders to handle multiple services designed for developers (e.g. for backend, database, hosting, etc) The fundamental problem: these AI app builders just cobble together existing developer tools and slap AI on top, but these tools were designed for humans and not for AI. The result? Non-coders get excited, start building, hit a wall, and then abandon their projects. Floot is purpose-built for AI. Our secret sauce: 1) Instead of reusing a coding framework designed for humans, we created a specialized framework that dictates how AI should write code and how the code runs on our infrastructure. This allows us to enforce best practices, detect errors earlier, and give the best feedback to the AI. As a result, Floot can write better code and fix issues more effectively. 2) Floot has the entire tech stack built-in (backend, database, hosting, etc) so building and managing an app feels seamless, especially for non-coders. And because we control every layer of the stack, we can optimize each layer for AI-first coding. Because of this, non-coders can get more done with less time and prompting. They can finally build serious apps that work, instead of getting stuck in frustrating error loops and then abandoning their projects. We also built a highly scalable hosting system directly on AWS so Floot apps can handle real traffic and business demands. This means non-coders can build, deploy, and scale their apps on a single platform seamlessly. Plus, Floot is really fun to use! Try building an app at floot.com

FlowDeploy helps bioinformaticians manage their data analysis pipelines. We provide everything they need to try, run, develop, and share their pipelines. That includes integrations with AWS, Snakemake, Nextflow, GitHub, Slack, SSO, and more, as well as a clean API and web app for launching and monitoring pipelines and managing their data. FlowDeploy is built for bioinformaticians: it doesn't restrict how pipelines are built and managed, as long as a bioinformatics workflow manager like Nextflow or Snakemake is used. But it does eliminate several footguns like idle spend and accidental data egress, and it reduces the potential for users accidentally sharing credentials. FlowDeploy runs the pipelines in either our managed cloud or the customer's cloud – eliminating the need to transfer data externally. Non-computational biologists can use FlowDeploy, too: features like pipelines templates decrease the complexity to launch a new pipeline, which reduces user error and decreases the need for advanced cloud training for non-computational users.
Flower Labs is the world-class AI startup behind Flower, the most popular open-source framework and ecosystem in the world for training AI on distributed data and compute resources using federated learning. Trusted by industry leaders such as Mozilla, Banking Circle, Samsung, Temenos and Bosch, Flower empowers organizations to improve their AI models on sensitive data that remains securely distributed across organizational silos or user devices. In a world where most AI relies on centralized public datasets - just a fraction of the data available - we believe unlocking access to (orders of magnitude more) private data will drive the next breakthroughs in artificial intelligence. Flower Labs is a Y Combinator (YCW23) graduate and backed by top-tier investors and renowned angels, including Felicis, First Spark Ventures, Mozilla Ventures, Hugging Face CEO Clem Delangue, GitHub Co-Founder Scott Chacon, Factorial Capital, Betaworks, and Pioneer Fund. Together, we are redefining how AI is built, deployed, and scaled for privacy, collaboration, and real-world impact.

FlyCode helps subscription merchants maximize revenue. We reduce involuntary churn by managing payment failures intelligently. We’re Jake, Etai, and Tzachi and we’re building FlyCode. TL;DR: If you sell SaaS or B2C subscriptions, we’re here to help you recover lost revenue due to failed payments and involuntary churn. ‘Involuntary’ or ‘Passive’ churn is a hidden Revenue Killer 💳 for Subscription Businesses ❌ THE PROBLEM: Recovering Failed Payments is Complex Involuntary churn refers to the loss of subscribers due to payment failures, not due to them actively canceling. While it is both possible and a worthwhile strategy to attempt to win back a customer during the cancellation process — involuntary churn is not intentional and in most cases, your customers aren’t even aware that their payment failed. 💰 Bottom line? Effective payment optimization does reduce involuntary churn and will increase ARR by as much as 5-10% FLYCODE SOLUTION 💡 FlyCode leverages ML and AI to provide Payment Optimization and smart payment retries to maximize subscription revenue and reduce churn. We apply a unique model tailored to each Merchant and their customers to ensure optimal results. ⚡️Automatically recover failed subscription payments and reduce passive churn ⚡️Use ML & AI based payment optimization to find the best time to charge your customers ⚡️ Improve customer experience by coordinating payment retries with customer emails/SMS 🛠️ We support OOTB + Custom Integrations for Merchants and White-Label for Platforms

Fogbender helps B2B companies support customer teams: think Intercom meets Slack's shared channels. Today, all customer software is explicitly or implicitly designed for helping individuals, not teams. This is forcing B2B companies - who sell products to teams, not individuals - to augment their default customer support platform (Zendesk, Intercom, Front, etc) with a second, "unofficial", system: Slack's shared channels. This causes a number of operational and logistical difficulties for both vendors and their customers, resulting in added costs, inefficiencies, and lost opportunities. With Fogbender, B2B vendors embed a team-to-team messaging widget directly on their customer dashboard, where all users belonging to an account can - with no additional authentication - 1) see a list of currently-open issues 2) participate in conversations with their own team and the vendor, and 3) search all historical discussions.

America once turned breakthroughs into abundant products with unmatched speed. Our edge wasn’t just invention; it was the ability to prototype, iterate, and scale production faster than anyone else. Over time, we kept inventing but lost production velocity. High-volume manufacturing moved offshore, and low-volume, high-mix production became slow, fragmented, and burdened by overhead, quoting, programming, scheduling, and coordination. For decades, fixing this wasn’t economical. The indirect workaround costs more than the production itself. That constraint is no longer. New tools now automate the cognitive layers that once slowed everything down, collapsing weeks into days and turning overhead into code. For the first time in decades, fast, flexible domestic production can be economically superior. We’re rebuilding America’s productive edge by accelerating high-tech, low-volume, high-mix manufacturing, helping hard-tech teams prototype faster, launch sooner, and build more here. If you want to restore American productive power and ship real hardware, reach out. founders@foundation-industries.com

Ben and Jacob met in Calculus class in 10th grade, and tried founding a startup in high school — it didn’t go anywhere. During high school, Ben lead the frontend team for the World Health Organization’s COVID-19 App Team. After high school, Jacob went to Apple and Ben went to college. When there was an opening on his team, Jacob had Ben apply, and Ben left UChicago to go work at Apple. They spent about 2 years at Apple as Senior Engineers in the Conversational Engineering Department, before leaving to found Freestyle. Freestyle is directly inspired by what they saw as their failures of the tech they worked with at Apple.

Fresco is an AI-powered takeoff and estimating for Division 8 construction (doors, frames, and hardware). Estimating Division 8 has always been brutally manual: flipping through hundreds of pages of specs, cross-referencing hardware sets, and building out schedules by hand. A single missed door or misread hardware group can kill a bid's margin. Fresco automates the entire takeoff process with 99% accuracy, cutting the time estimators spend on takeoffs by 70%. We've processed 3,000+ takeoffs for general contractors and Division 8 subs, and we're becoming the system of record for how this trade gets estimated. Division 8 is our beachhead: it's complex enough that AI creates massive value, and siloed enough that the incumbents haven't solved it. We're starting here and expanding across the spec trades.
We are transforming eCommerce and Direct-to-Retail fulfillment for Businesses that sells Cold Chain products.

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.
