The most interesting startups from the autumn 2025 Y Combinator batch

Bear
Bear helps brands stay visible in the era of AI search. When people search for information through ChatGPT and other AIs instead of Google, brands become "invisible"—they simply aren't shown in the responses. Bear ensures companies appear in AI-generated answers and are found where decisions are now being made.

OpenBuilder
OpenBuilder is a free platform for non-technical creators that helps turn ideas into products. Fees are only charged for assistance with challenges and launch preparation.

Lightberry
The "social brain" for robots. It gives humanoid robots vision, hearing, speech, and movement so they can interact naturally with humans and work autonomously.

Koyal
Koyal is an AI-powered film creation platform that transforms scripts or audio into personalized and visually impressive stories.

Parrot
The "TikTok for language learning." People become fluent not through flashcards, but through sound, context, and repetition. Parrot turns short videos into effective learning, using the familiar TikTok format as a tool for real language practice.

Boom AI
Helps online stores avoid losing visitors. Boom is an AI sales assistant that works 24/7, answers questions, helps with product selection, and converts "lost" users into buyers.

Everest
Everest provides AI support engineers for IT outsourcing firms, automating routine and complex IT tasks, thereby increasing margins and reducing reliance on human staff.

Aside
Sales are lost when managers falter under pressure. Aside fixes this with AI that provides real-time prompts for the right response. No more "I'll check and get back to you." Only confident, converting calls.

Fastshot
Fastshot is a no-code platform for building mobile apps. It allows anyone to develop an app in a few days by chatting with AI, from idea to publication in the App Store.

Nucleo
Nucleo helps oncologists extract data from CT scans for tumor characterization and treatment—already working with Stanford University, Cedars-Sinai, and Weill Cornell.

Jarmin
Jarmin.ai is an ML engineer you can hire. Simply talk to Jarmin like an employee, and it completes ML tasks, takes initiative, and manages projects.

Articulate
Articulate is a platform for construction and solar projects that automates design review, error detection, request generation, and team synchronization, helping save time, money, and avoid rework.
