Building your parents' favorite tech company @rhem_labs

[Jacob Shen @jacobshenn]

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.

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.

https://t.co/EXddQImgCo 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!

@_j400x_ Just checked out trymyfriend. Really really cool product, love the work you've been doing. Keep it up!

[Jacob Shen @jacobshenn]

Start with one thing they already find useful: making calls, getting things done online, or figuring something out for them. Let them discover the rest over time.

We’ve found autonomy matters a lot too: it should feel like something that helps them, not something their kids installed to monitor them.

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.

[Product Hunt 😸 @ProductHunt]

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

[RoboIndex @roboindexio]

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.

@MiniYuanLip I graduated more than a year ago 😭 but thanks I guess haha

[Jacob Shen @jacobshenn]

@Sarah___Fan Can you help me write a introduction post as well 🙏

[Jacob Shen @jacobshenn]

@juaniandrr Haha, Heyato actually inspired us to add radio to Rhem too. Thought it’d be a fun feature :)

[Jacob Shen @jacobshenn]

Great question. We actually started by trying to build Rhem as an app.

We quickly realized the hardware needed to be the gateway to the software. That matters a lot when building for older adults because it lets us control the entire user experience instead of working around the phone, notifications, app navigation, passwords, etc.

The intelligence is in the software but the hardware is what lets us deliver that software in a way that actually works for the people we’re building for.

[Jacob Shen @jacobshenn]

@superdapp @rhem_labs That’s exactly what we’re hoping to do, help families stay a little closer and catch things earlier.

[Jacob Shen @jacobshenn]

@AnaisHowland18 @rhem_labs Thank you Anaïs!! Been waiting a long time to finally stop being mysterious about what we’re building

[Jacob Shen @jacobshenn]

@jcarrasco171 @garrytan @rhem_labs Pretty cool is exactly what we were going for 😎

[Jacob Shen @jacobshenn]

@edwardahn9 @rhem_labs ✊

[Jacob Shen @jacobshenn]

@thermoagentai @rhem_labs Great suggestion, one of our core design principles is actually to reduce the need for the screen altogether. Rhem is voice first so the screen only shows important decision moments and comes in only when it genuinely makes a task easier

[Jacob Shen @jacobshenn]

@mihalsid @rhem_labs Definitely a big problem to go after, excited to earn our place in it

[Jacob Shen @jacobshenn]

@WhyParabola @rhem_labs Thanks Aman

[Jacob Shen @jacobshenn]

@kul @rhem_labs That’s exactly it, small changes shouldn’t have to become big problems before families notice. Appreciate you for believing in the mission

[Jacob Shen @jacobshenn]

@ycombinator @rhem_labs Couldn’t have done it without YC. Just getting started 🫡
