my dad and i built a robot for your parents.
today we’re launching @rhem_labs
our family spent nearly 20 years caring for my grandmother and aunt at home. we saw small health changes go unnoticed between check-ins. and simple things, like making a call or booking an appointment, meant waiting for someone else to help.
we built the robot we wish they’d had.
your parent just talks to Rhem. it helps make calls, book appointments, manage reminders, and get everyday things done online.
through the family app, you can follow changes in health readings and routines, see what Rhem handled, and step in when you’re needed. your parent chooses what to share.

Looking for industrial designers who want to redefine how humanity sees robots.
We’re creating a new design language for humanoids. The robots people will welcome into their homes, grow up alongside, and share their lives with.
DM me your portfolio, or tag someone who should help shape this future.
They had the most baller demo I’ve ever seen. Gave their product $100, went to lunch and came back to $153. 🫡
Introducing AnyAlpha (YC F26) @AnyAlphaAI , the agentic trading platform.
AnyAlpha turns your trading idea into an agent that executes it for you, 24/7.
Every agent runs on institutional-grade data and the trading infra we built.
Start with an idea. Work it out with AnyAlpha. Backtest it on historical data. Then your agent starts trading.
We're starting with prediction markets, then every asset class.
Try it! 👉 anyalpha.ai

anyone applying to YC W27 with a hardware startup?
drop what you're building below 👀
would love to meet more hardware founders

We're building self-improving agents to automate tedious, repetitive operational work @GrepdotAI. At IG, a UK online brokerage, Grep agents review compliance alerts, helping over 80% of traders onboard without manual intervention. IG is now a FTSE 100 company.
Operational work often means following a specific procedure, gathering information from different sources, checking it against what's needed, and deciding what to do next.
The steps are repetitive, but no job is the same, making the work tedious to do by hand and hard to automate with workflows alone. Meanwhile, using frontier agents to reason through every task is often too expensive to scale.
Grep.Al gives you an agent workforce that:
-> Takes minutes to create and are domain experts with the right skills and tools from day one.
-> Learn from every run, moving repeatable steps into code and workflows and saving frontier intelligence for exceptions and unfamiliar cases.
-> Get smarter and cheaper as they scale using our AgentRun harness.
-> Runs on our managed agent platform with secure sandboxes, audit logs, evals, cost controls, team sharing, and access controls included.
Grep AI agents are available on demand and can run on schedules or in batch. Access them via the console, MCP, API, or SDKs that integrate into your existing workflows.
Our customers, including IG, Airwallex, Worldpay, FV Bank, and Citizens Bank, have saved more than 250,000 hours of operational work with Grep Al agents across onboarding, doc verification, compliance, underwriting, operations, HR, GT ops, market research, and business intelligence.
If operational bottlenecks are slowing your business down, create an agent workforce with Grep to automate them in minutes.
P.S. We're in the @ycombinator Fall 2026 batch!
most technology is built for 20 year olds and then we act surprised when our parents don’t use it.
we need to do better.
Tech isn’t just for the young and bold.
When aging parents begin to decline, the earliest warning signs often go unnoticed until it’s an emergency. Meanwhile, simple daily friction slowly strips away their independence.
That’s why @jacobshenn built @rhem_labs.
It’s a tabletop health assistant robot that aging parents can simply talk to for everyday support, while running quiet wellness check-ins that give families early visibility before small issues escalate.
It gives parents their autonomy back, so their kids can stop managing logistics and just be family again.
THE major market
A father-and-son YC team just launched a $1,099 robot for aging parents.
Rhem tracks health readings, makes calls, books appointments and manages reminders.
Eldercare could become one of the first major home robotics markets.

This is the future of research. Do not bet against these guys.
The world spends roughly $100 billion a year on experimentation in Life-Science. Yet, 93% of drug programs entering Phase I never reach approval.
Halmos Labs is changing that

This reel went viral on our Instagram.
We started this series hoping to bring people closer to their parents.
But sometimes that distance is there for a reason...
NVIDIA made a $100,000 desktop PC
finally a machine powerful enough to run:
- Slack
- Notion
- 63 Chrome tabs
- one Cursor agent deleting my entire codebase
- another Cursor agent putting it back
we are so back
The US isn't behind on robot demos. It's behind on robot hours. China is collecting failure data in factories and apartments. We're collecting footage. We close it by shipping machines that HAVE to work when nobody's filming.
