Skillnest
A subscription skill layer that teaches any home robot your house, learned from every other house.
Skillnest is a consumer subscription that rides on top of home robots sold by other manufacturers: the household demonstrates a chore once by phone or by guiding the arm, and Skillnest turns that demonstration into a policy that runs on their machine and, once anonymised and verified, on everyone else's.

Test it before you build it
$600 · 3 weeks · 30 prospects
For $600 and 3 weeks, proves whether enough US households actually own a manipulation-capable home robot and whether those owners will put $25 down for a taught dishwasher skill.
Riskiest assumption · Enough US households already own a manipulation-capable home robot that 30 identifiable owners can be found within a week, and at least a quarter of them will pay a $25 deposit for a taught dishwasher skill.
1Focus group: who and where
A US household that already owns a manipulation-capable robot - a Unitree G1, an early 1X NEO, or a Hello Robot Stretch 3 - bought it out of enthusiasm in the last 18 months, and is frustrated that it demos well but does no daily chore.
where to find 30 · r/robotics and r/homeautomation on Reddit, where owners post setup videos and complaints; the official Unitree and Hello Robot community Discord servers, where owners troubleshoot by model; YouTube reviewer channels that unbox the Unitree G1 and 1X NEO, whose comment sections and member Discords are where buyers self-identify.
2Sell first, build later
A dishwasher load-and-unload skill taught from the owner's own one-time demonstration, delivered as a beta to founding households on supported robot models within 6 months, with the founder personally onboarding each home.
the ask · $19 per month per household, founding rate locked for the first year; $25 refundable reservation today
a real yes · A real yes is a completed $25 card charge; upvotes, 'take my money' comments, waitlist emails without a card, and enthusiastic Discord replies do not count.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Owner census
$0 · 7 days
Spend 7 days enumerating named US owners across the three channels: search Reddit post history, Discord introductions and YouTube comments for people stating they own a G1, NEO or Stretch 3 and live in the US, and log each with model and evidence link. This attacks the installed-base assumption directly before a dollar is spent on anything else.
keep going if · 30 named US owners with model evidence found within 7 days
2. Chore and price interviews
$150 · 10 days
Book 15 video calls with census owners, $10 gift card each, and have them show the robot live on camera. Ask what chore they would pay for, whether their machine could physically attempt it, and read the $19 a month price aloud to watch the reaction.
keep going if · 10 of 15 owners name a chore they would pay $19 a month for and confirm their robot could physically attempt it
3. Charged reservation page
$450 · 10 days
Launch a one-page site with a $25 card-charged refundable reservation for the founding dishwasher-skill cohort, listing supported models; an online card checkout is used here because a $25 remote consumer payment has no other credible rail. Send it to all 30 census owners and post it once in each channel where rules allow.
keep going if · 8 of 30 contacted owners complete the $25 charge
4. Maker preinstall probe
$0 · 14 days
Email business development at Unitree's North America team, Hello Robot, 1X and Nori proposing a revenue-share preinstalled skill app, two paragraphs each, from the founder. This tests the distribution channel the card depends on without waiting for it.
keep going if · 2 of 4 makers take a call about preinstall terms
4Collect a deposit up front
Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.
$25
per prospect, refundable
how · A $25 refundable reservation charged to the owner's card at an online checkout; the owner ticks a consent box naming their robot model, nothing else is signed. Chosen because this is a consumer paying a small amount remotely, and the card charge itself is the measurement the census and interviews cannot fake. set up: Stripe Checkout ↗
what it reserves · A founding-cohort slot for the dishwasher skill on their robot model and the $19 a month price locked for their first year.
refund · Refundable in one click at any time before the skill ships, and refunded automatically if the skill has not shipped for their model within 6 months.
target · 8 reservations from 30 contacted owners within 21 days
before taking money · Do not collect or store in-home camera footage from any tester before a written consent and deletion policy is reviewed by counsel, and keep children out of every demonstration recording.
Go: build it if
30 named US owners found in 7 days, 10 of 15 interviews name a chore they would pay $19 a month for, and 8 of 30 owners pay the $25 reservation within 21 days.
Kill: stop if
Fewer than 15 identifiable US owners after 14 days of searching across all three channels, or fewer than 3 of 30 contacted owners pay $25.

outreach message
Saw your posts about your Unitree G1 - you own one of the few robots in the country that can actually grip a plate. I'm building Skillnest, a subscription that teaches your robot chores from one demonstration, starting with loading and unloading the dishwasher, $19 a month when it ships. I'm picking 20 founding households to shape that first skill. Do you have 20 minutes this week for a video call to show me what your robot can and can't do today?

The idea in full
- What
- Skillnest is a consumer subscription that rides on top of home robots sold by other manufacturers: the household demonstrates a chore once by phone or by guiding the arm, and Skillnest turns that demonstration into a policy that runs on their machine and, once anonymised and verified, on everyone else's. It ships as a preinstalled app through robot makers and large electronics retailers, who take a share of the monthly fee. The technology is a vision-language-action stack with per-home adaptation, plus an on-device consent and redaction layer that keeps camera frames from leaving the house unless the user releases them.
- Why now
- Nori (yc S26) is building a sub-$2000 humanoid you can teach to do anything and Aktoria Robotics is building human as API for robots, while Hemlock (yc F26) sells a force-sensing wristband for training robotic AI, so demonstration capture is becoming standard. K-Scale Labs died in 2024 doing open-source humanoid hardware, which is the evidence that the durable position is the skill layer above the machine, not the machine.
- Wedge: first customer and entry point
- One robot maker's early-access owners in three countries, one chore that everyone hates and every kitchen shares: loading and unloading a dishwasher, priced at a low monthly fee.
- Path to 100x
- Household service work is a $10-100B addressable subscription market as soon as capable arms cross a consumer price point, and skills compound: every home that teaches a chore improves the robot of every other subscriber, which is a direct network effect on product quality rather than on liquidity. That makes one skill layer worth joining and the second one worthless, and a category is born when consumers buy the robot for the skills rather than the hardware.
- Ceiling
- Robot manufacturers treat the skill library as the whole product and refuse to let a third party own the customer relationship, leaving Skillnest as a licensed component priced like a chip.
- Closest real companies, as the generator saw them
- Nori sells the robot and would be a distribution partner rather than a rival; Aktoria Robotics builds the human-to-robot interface, which Skillnest consumes; Moving Atoms and Robocurve evaluate and train robots for developers, not for households with a subscription.
- Main risk
- Home robots stay a rounding error in installed base for another decade and there are simply not enough households to start the flywheel.
Five judges
Each judge scores every idea in the catalog with a named rubric; the venture judge decides whether a card is shown at all (4-5 is venture-grade).
Venture investor
4/5
Every household that teaches a chore improves every subscriber's robot, a direct quality network effect that makes the second skill layer worthless.
Bootstrapper
1/5
A consumer subscription that only works once home robots exist in volume, which the card itself admits could take a decade.
Operator
1/5
A subscription skill layer for home robots that barely exist requires the entire consumer robotics installed base to arrive first.
Technologist
2/5
The whole thesis rides on cross-home skill transfer working on other makers' hardware, a capability that does not yet exist at consumer reliability.
Risk
1/5
Ships preinstalled through robot makers who the card itself says may treat the skill library as their whole product.
trends
3/5
Robotics jumping to 13% of S26 and Nori's sub-$2000 humanoid are real 2026 signals, but the installed base the flywheel needs does not exist yet.
