Celery emerged from Y Combinator in 2012 with one goal: to help you sell your great ideas, better. Filling a void in e-commerce, Celery has become the single-stop for innovative brands – large and small – to take pre-orders, crowdfund independently, and to continue selling before and after items are in-stock. Today, Celery has helped thousands of businesses launch their way by providing the tools to crowdfund and pre-sell independently. Celery is founded by a team crowdfunding and e-commerce experts and alums from MIT, Stanford, Groupon, LinkedIn and Foursquare, and is venture-backed by Y Combinator, General Catalyst, Elementum Ventures, Max Levchin, SV Angel, and other top investors.
Celest is a backend-as-a-service for Flutter and Dart developers. It empowers Flutter developers with the tools and capabilities they need to become full-stack developers. We are introducing "Cloud Widgets", a set of primitives which enable you to declaratively define every piece of your backend and infrastructure in Dart. As the role of the front-end developer evolves towards full-stack proficiency, we recognize that existing tools have fallen short for those specializing in Flutter. Using the programming language and patterns Flutter developers already know from building their frontend, Celest enables developers to build and connect their apps to their backend with no additional tooling. We enable Flutter developers to concentrate on building features and delivering value to their customers rather than learning additional domains and fragmenting themselves across disparate toolchains.
At CellChorus, we apply artificial intelligence to evaluate thousands of microscopy videos in parallel to evaluate how immune cells move, interact and perform over time.

Cenote uses AI to automate the back office for medical practices — eliminating the bottlenecks that often delay patient care and clinic revenue. Typically, practices hire teams to manually extract patient info from hundreds to thousands of faxes a week. This slow process risks losing patients to faster competitors. Cenote’s software streamlines this workflow. There are 330,000 medical practices in the U.S Capturing $50,000 per practice presents a $16.5 Billion opportunity. The team behind Cenote—Kofi, Ajani, and Kristy—met in San Francisco and bring deep expertise in building scalable solutions for highly-regulated industries such as climate and gov tech.
Centauri AI is a modern ETL and Data Science platform for banks and investment firms, starting with Structured Finance. Financial firms heavily rely on Excel, PDF, and PPT files to exchange complex asset details, leading analysts to spend hours crunching the files and extracting insights. Moreover, these data files and reports cannot be easily reused due to poor data infrastructure. Powered by AI, our product cuts hours of data wrangling work down to minutes and makes it possible to query past data easily. This helps firms evaluate assets faster and win more deals. Since launching last month, we've started a pilot with a brokerage team at a public investment bank that now uses our product daily. Aiming to serve over 100,000 investment teams needing complex data analysis for alternative investments, this opens up a potential $5 billion market.

At Cero, we solve specific coordination tasks between hospitals and patients, such as appointment confirmations and last minute cancellations, by automatically communicating with patients over WhatsApp. For example, a patient can confirm and reschedule their appointment without needing to call anyone. Almost half of the medical appointments in Latin America are missed because patients simply do not show up. This ranges from missing a regular dentist check to missing an expensive MRI scan. With increasing pressure to improve access to care in developing countries, optimizing communication and coordination with patients is a key task to achieve. This is a massive problem especially in places where most people don't know how to effectively use self-service mediums (or are too busy to use them). We bootstrapped the company and we are profitable. As of August 2021 we have $97K in monthly revenue from 15 clients with a CMRG of 20% in the last year. We have 100% logo retention and we grow with our clients. We are currently coordinating over 600,000 medical appointments every month, just in Chile. This problem represents a $3.5B market opportunity in Latin America only. Latin America has 650M people, each one having an average of 3 medical consultations per year. We charge for every time we effectively communicate with a patient. We plan to handle several coordination interactions with every patient for each consultation, which considers a roadmap of scheduling, confirming, booking, reimbursements, payments, among others. We are a team mixing strong knowledge about the healthcare industry with deep technical skills. Felipe (CEO) is a former dentist that has led deep changes in healthcare payments in Chile. Mauricio (CTO) and Jorge (R&D), both PhD in Computer Science, led the creation of the most advanced Spanish Language Neural Network used daily by scientists and practitioners in LatAm (BETO: Spanish BERT). In a weekend project, Mauricio and Jorge automated the communication with students attending a summer school obtaining impressive engagement. Felipe was struggling with contacting his patients to coordinate appointments, and saw a big opportunity in this technology. The three together have designed and run a solution that as of 2021 is coordinating over 600,000 patients per month in their home country, Chile.
Cerrion helps manufacturers automatically detect, understand and eliminate problems on their production lines using video-based Computer Vision. Our AI leverages standard CCTV cameras and learns how a manufacturing process looks like when things are going well and can automatically detect and track problems in real-time. For example, one of our customers, a Pepsi supplier producing 500 bottles per minute now automatically detects and reacts to a fallen bottle before it starts blocking their production line.
Certus AI is replacing the restaurant phone line with Voice AI. Restaurants lose up to $100,000 per year per location from missed calls, lost orders, and abandoned hold lines. Staff are overwhelmed. IVRs frustrate customers. Call centers are expensive and impersonal. It’s 2025. Guests don’t leave voicemails or wait on hold. They just move on. Certus is an AI voice agent built for restaurants. It answers every call, 24/7 — taking orders, processing deliveries, booking reservations, upselling, and handling complaints in English, Spanish, French and more. Certus is built to manage the phone line end to end, from the customer call to the restaurant tech stack, with zero human intervention required. It currently integrates with industry-leading systems like Toast, Square, Clover, UberEats, DoorDash, and more. We’re building the voice layer of the modern restaurant — the employee they’ll never fire. We started Certus because we lived the pain. Gurveer (CEO) grew up answering phones in his family’s restaurant and helped operate them, growing from 1 to 11 locations in 7 years. Later, he and Adam (CRO) ran a restaurant growth startup to help others increase revenue, but kept watching clients bleed cash because no one picked up the phone. So we built the solution the industry always wished existed. Until now, this problem was considered unsolvable. But Voice AI has finally crossed the conversational chasm and 72% of consumers now prefer AI over humans as long as it means faster and better service. More importantly, the market is begging for this. The North American restaurant industry crossed $1 trillion in 2024, and it's projected to hit $1.5 trillion in 2025. Yet over $100 billion is still lost annually to missed calls, human error, and outdated tech. As the market continues to grow, so do the losses! Our customers say it best: - “Certus changed my life overnight.” - “We were losing the ability to give great in-house service — the phone was killing us.” - “70% of my business comes through the phone. That’s mine and my 16 staffs livelihood.” - “Before Certus, I used to lose 40 - 60 calls a day…. now my printer just stays printing!” - “I’ve been in the business 38 years. I’ve been waiting for this since then.” Certus is here to fix the $120B phone problem — one call at a time. And in doing so, we’re redefining how the restaurant industry communicates forever, starting with the phone line.

Channel3 is building a database of every product on the internet. Google and OpenAI maintain vast product graphs, but keep that valuable data to themselves. Channel3 gives every developer access, opening a world of possibility for new shopping experiences across any vertical. For instance, developers could build AI fashion stylists or give their agents shopping capabilities. We don’t just collect product data; we actually understand it. With the latest image classification and reasoning models, we can match products across merchants—even when listings and images differ—recognize variants, and surface the perfect matches for every search. As we grow, we’ll capture unique insights into what users want, click, and buy. As AI models get smarter and cheaper, our flywheel accelerates: our catalog will improve, and it will be even easier for developers and vibe-coders to build on our infrastructure. To further incentivize building on Channel3, we provide built-in monetization; developers earn commissions on sales they drive. Alex discovered this need while building an AI tutor that could recommend products and earn affiliate revenue. When no solution existed, he persuaded his smartest friend from Duke and former co-founder George to leave Palantir and build Channel3 together.
Charge Robotics is building robots that automate the most labor-intensive parts of solar construction. Solar has rapidly become the cheapest form of power generation in many regions.
