2025 is shaping up to be the "year of AI agents". We've put together a list of startup ideas that we think are especially promising— some draw attention to trends that are already in full swing, and some of them are where we think things are going next. ycombinator.com/rfs
Full-stack AI companies @snowmaker If you build a great AI accountant, why sell it to legacy accounting firms when you could start an AI accounting firm and beat them? We think founders will increasingly choose to do just that, and we're excited to fund more of these full-stack…
More Design Founders @aaron_epstein As AI tools make coding easier, great design and taste matter more than ever. That's why more designers should become founders. Don't just design products – create companies.
Voice AI @gustaf Phone calls with businesses haven’t changed in decades—until now. Voice AI bots, powered by LLMs, are finally as good as humans. It’s the autonomous car moment for voice.
AI for Scientific Advancement @sdianahu AI is transforming how physical things are made. Many scientific tools haven’t changed in decades, but test-time compute is now enabling new startups to solve complex problems in fields like chemistry, biology, and materials science.
AI Personal Assistant @t_blom It’s high time we had AI personal assistants. Imagine an AI that has perfect understanding of your emails, projects, and scheduling preferences — and can take actions on your behalf. Apply to YC if you’re working on this idea!
AI Personal Tutor for Everyone @harjtaggar The latest multimodal and reasoning models make it possible to create an AI personal tutor that’s capable of explaining complicated concepts to anyone who’s interested in learning them. This could really change the world. We’d love to…
Healthcare AI @gustaf US healthcare spend is now more than $4T a year, but over $1T of that is spent on manual admin tasks. New agents and LLMs can automate this.
AI Residential Security @bosmeny Legacy home security companies are a $20B joke. Meanwhile, AI is already preventing crimes in office buildings–think facial recognition, loitering alerts, even virtual guards to yell at intruders. We think the first startup to bring…
Software Tools for Robots @sdianahu Robotics hasn't had its ChatGPT moment yet, but we think it’s almost here. With the rapid improvements in foundation models, it's finally possible to make robots that have human-level perception and judgment. That’s been the missing piece.…
Internal Agent Builder @koomen Soon, all companies will have one thing in common: every employee will build agents to automate the repetitive parts of their jobs. We’d like to fund founders working on the infrastructure they’ll use to do that: internal agent builders.
The Future of Education @t_blom If you fast-forward 10 or 20 years, it’s impossible to believe that education is still going to be done in the same way it is today. Do you want to figure out what the future of education looks like? We’d love to see a YC application.
AI Research Labs @snowmaker There are still many unsolved problems in AI, and we think the world needs more AI research labs working on them. Some people think that YC doesn't fund open-ended research, but as the first investors in OpenAI, we are extremely comfortable doing…
AI Voice Assistants for Email @bosmeny Let’s talk. What if, every day while you drive to work, you could get to inbox zero – with just your voice? Siri was supposed to be this! But Apple’s stumbles may have created the perfect opening for an ambitious startup to build the…
AI for Personal Finance @gustaf Most people struggle with personal finance. LLMs can fix that—by offering personalized, unbiased advice at scale.
If you’re interested in working on any of these ideas, you should apply to YC. The deadline for applying to the summer batch is May 13th: ycombinator.com/apply
@louisjoejordan weren’t you building an @ElevenLabsDevs demo for this? 👆
I'll try building this now. Think it should take about a few days. Gmail MCPs already available. Will reply when done.
Tbh Inbox zero with my voice sounds more like a nightmare than a feature. The dream is not needing to check email at all. Don’t optimize the interface.. optimize for not having to respond in the first place. Voice interactions should be near zero too.
Given soon all of this will be managed automatically and you won’t be driving why is this framed like this at all?
Go through your emails while brewing some tea
New Feature: Call your inbox 📥 You are busy. You need to walk your dog, cook breakfast for the kids, and steep your morning tea. Dash AI’s new “call your inbox” feature lets you interact with your inbox with just a phone call - receive morning email briefs, draft messages,…
We're building exactly this!! hitom.ai And we're making it a social enterprise following Toms shoe model where for every paid subscriber, we can give it for free to blind and visually impaired people. In beta. About to raise a round soon. Shall we chat?
Couldn’t agree more! We just launched our voice-controlled inbox and calendar assistant. Would love your feedback: x.com/assistant_2889…
47,112 unread emails but now I can talk my way to inbox zero Just say the word—Lynq’s voice agent sorts, drafts, and sends while your hands stay free
Been living this for weeks with Blitzermail.com My inbox is scared of my morning drive now
