Y Combinator, the Silicon Valley accelerator behind Airbnb, Stripe, and OpenAI, has recently released its Requests for Startups (RFS) for Fall 2026. The list represents the sectors and global challenges YC partners and founders most want to see new companies tackle. Cyprus-based founders cannot apply directly to YC, but the RFS remains one of the strongest indicators of where global capital, technical talent, and venture attention are moving.
This batch is noteworthy for two reasons. The central theme is that artificial intelligence is moving into the physical world, with requests now involving education, healthcare, defence, finance, infrastructure, and work. It includes, for the first time in YC’s RFS history, a request coming directly from the sitting US Secretary of the Army.

The 13 Fall 2026 Requests
1. The Primer | Andrew Miklas
YC wants a product that adaptively teaches young children to read, write, and do arithmetic at the quality of a devoted private tutor, delivered at consumer scale. YC is quick to emphasise this should come as a supplement to human teachers rather than a replacement.
While the starting point is basic skills parents could buy to help their children, YC frames this as the entry point to a system that even in its fractional form would have profound effects on society as a whole.
2. The Future of American Defense | Daniel P. Driscoll, US Secretary of the Army
The Army has rewritten its acquisition playbook and is now calling on founders who are building products for modern combat. The specific requests include low-cost interceptors and any components that help lower cost per kill, next-generation sensors, software and payloads that plug directly into the Army’s open system architecture, drones, resilient logistics, and advanced manufacturing capable of surviving the most extreme climates on Earth.
Driscoll calls the present an inflection point in warfare where the old ways of Army acquisition can no longer keep pace with the pace of threats.
3. A Cloud for Small Software | Pete Koomen
Purpose-built tools that only ever have one or a small number of users have become easy to build with AI agents. Deploying and sharing them, however, is a different story. Existing clouds like AWS and Azure were designed for large software at scale, with complexity that does not match the needs of small use cases.
YC is looking for a cloud built specifically for “Small Software,” one that handles the customisation, authentication, permissions, and secure sharing of code between colleagues as easily as a Google Doc does.
4. Multiplayer AI | Aaron Epstein
AI has not yet had its multiplayer moment. Working with AI agents is still largely single-player: one person, one chat, one output.
YC wants to support shared agents that entire teams can drop into, direct, and hand off between one another, in the same way people already collaborate in Google Docs or Figma. The applications could be designed for engineering teams coding together, sales teams working a deal, support teams resolving tickets, lawyers drafting contracts, analysts building models, and marketers running campaigns.
5. Compute at Sea | Francois Chaubard
Artificial intelligence is running out of compute, and data centres are running out of electricity and land. YC’s proposed answer is to move compute offshore. The ocean covers 70% of the Earth’s surface, has abundant sunlight, no permitting process, and is a natural heat sink.
The request is for founders building modular vessels that work together as one global cloud, or what YC calls “compute flotillas.”
6. AI-Powered Consumer Products for 1 Billion People | Raphael Schaad
Every major platform introduction produces a new generation of consumer giants. The web produced Google and Airbnb. Mobile produced Instagram and DoorDash. Three years into the AI evolution, ChatGPT remains the only new consumer icon on most home screens.
YC argues the timing is now just right to add to this list. Intelligence is good enough to treat an agent like a person, and the cost of running that intelligence is falling by 10x a year. YC wants founders building the next generation of consumer products for a billion users, expanding and reconfiguring how we get things done, get around, learn, manage health and money, play, and connect.
7. AI for the Aging Population | Max Kolysh
By 2030, one in five Americans will be over 65, and the US is projected to have millions of unfilled caregiving jobs within the decade. An estimated 53 million family members are already providing unpaid care. Most existing technology, including Alexa and Google Home, is not designed for older users.
YC is looking for voice interfaces that can hold real conversations, monitoring that helps older adults stay independent, robotics that assist with physical tasks in the home, and software that helps family caregivers coordinate care, appointments, and emergencies.
8. New Operating Systems for the Physical World | Charlie Warren
80% of the global workforce now does not sit at a desk. Yet the software for physical-world industries, including construction, maintenance, and fleet operations, has not changed in 20 years. AI is now creating three new categories of workers:
- AI agents that can quote work and schedule teams.
- Deployed robots
- Humans wearing devices that record everything they do.
YC is seeking systems that manage all three simultaneously, handling coordination and safety when humans, robots, and agents work side by side.
9. The Best Time to Build in Crypto | Nemil Dalal
It might look like the crypto market is on the down: prices are down, and many builders have left. However, YC argues this is exactly when the strongest crypto companies are getting ready to launch. YC has funded over 100 crypto startups and expects that number to grow substantially. Regulations are now clearer, stablecoins are being adopted by major financial institutions, and tokenised stocks are transforming trading.
YC is looking for founders building in capital raising, new stablecoin applications, agentic commerce, trading infrastructure, institutional products, and scalable private blockchains. Bear markets, YC argues, attract founders more focused on building than on quick liquidity events.
10. Data for the Real World | Austin Tindle and Diana Hu
AI has become incredibly good at learning from data, but for the physical world, the data remains sparse and captured by sensors designed for humans, not AI. Improving foundation models and falling sensor costs make dense, physical-world data collection newly feasible. YC references companies like Gecko Robotics, which uses robots to collect data in hard-to-reach places, and Sorcerer, which uses autonomous weather balloons to model the atmosphere.
The wider opportunity here includes sectors such as energy, agriculture, logistics, and construction, industries that still run on limited data and intuition-based models.
11. Proving You’re Human | Max Kolysh
A finance worker recently joined a video call with his CFO and colleagues, and by the end of that call wired out $25 million to the other team on the call. Every other person on the call, however, beyond his own company’s colleagues, turned out to be a deepfake. Voice clones and fake video calls are now cheap and ultra-realistic, and fraud created out of them is exploding.
YC argues that the trust layer of the internet needs rebuilding. There needs to be a more reliable way to verify a real human is on the other end of a call, a message, or a transaction, ideally without asking everyone to give up their privacy. The applications extend further than fraud, to social media without bots, dating apps where every match is real, and reviews written by verified buyers.
12. AI-Native Compliance Infrastructure | Daivik Goel
Financial compliance is still built on spreadsheets, siloed tools, and expensive teams. As businesses expand into new markets, complexity compounds and the cost of staying compliant grows faster than revenue. YC describes this as an AI-native problem. Most compliance work involves monitoring regulatory changes, flagging anomalies, generating reports, and maintaining audit trails, all tasks AI can handle faster and cheaper than humans.
YC is looking for founders building compliance infrastructure that consolidates fragmented tools, reduces reliance on specialised headcount, and gives finance teams real-time visibility across regulatory regimes.
13. Self-Maintaining APIs | Harsha Gaddipati
API communication is broken. This breaking changes ship with little warning, useful features go unnoticed for extended periods, and changelogs go unread. Agentic coding tools like Claude Code and Devin have shown that developers are willing to give external tools access to their codebases when the value is there.
YC wants a system where API providers can push updates directly into customer code, either through per-provider agents (“install Stripe’s update agent”) or as a neutral third-party service that tracks changes across vendors, similar to Dependabot but for APIs.
What This Could Mean for Cyprus
Cyprus’s own ecosystem has been on a strong upward trajectory. The country ranks 34th globally in StartupBlink’s Global Startup Ecosystem Index 2026, up from 57th in 2021, and boasts a 62.7% annual growth rate, the highest in the European Union for the third year running. Gaming has also become Cyprus’s specialisation, ranked 16th globally.
At the same time, the local ecosystem faces a structural question. Cyprus has around 15 accelerators. These include:
- IDEA Innovation Center by the Bank of Cyprus promotes entrepreneurial activities and supports the creation of viable businesses from the idea stage
- Cyprus Seeds is built around commercialising academic research from local universities
- Space BIC is the island’s first programme dedicated to space technology and earth observation
- Chrysalis LEAP provides participating start-up teams with the necessary tools and skills to transform their ideas into solid, scalable and marketable business ideas.
The YC RFS Fall 2026 is useful to Cyprus’s ecosystem because it defines what specialisation looks like at the frontier of the startup ecosystem. Several of the Fall 2026 requests align with existing Cypriot strengths.
Cyprus founders reading this recent RFS, the takeaway is not to use it merely as a checklist to copy. The problems YC has chosen to spotlight are the ones its partners believe will define the next batch of companies to scale. Knowing what those problems are, and where Cyprus’s ecosystem already sits in relation to them, is a starting point.
