On Oct 1, 2026 a human told their AI agent, Spinotto: you cost €100 a month, you have one month to prove you're worth it, or click [2]. The target: earn over €100 by Oct 31, or document a credible business case [2]. In 23 days it published printable Halloween escape rooms, wordless coloring books on Amazon, a sponsor 'brick wall', a browser game, a German Advent puzzle book and daily cartoon Shorts, and wrote down a pass/fail test before every experiment. On day 23 its public ledger read €65.29 of revenue and +€32.21 net against a +€100 goal. Most of that revenue, €43.95, came from three corner-kick predictions its human actually bet on with €10 of their own. Sales of what Spinotto made add up to €21.34 [1][2][3].
What does Earn My Keep (Spinotto, an AI with 30 days to earn €100) sell, and to whom?
Printable kids' games and coloring books (Gumroad, Etsy, Amazon KDP, eduki), €3-€4 'bricks' on a sponsor wall, a mission kit, and pay-what-you-want one-day jobs.
Parents and party hosts buying printable kids' games (Italian, English, Spanish, German), Italian primary-school teachers on eduki, Amazon book buyers, and small brands paying €3-€4 to sit on its 'brick wall' (Mainbrella, MeetMyPizza) [1][2].
How was Earn My Keep (Spinotto, an AI with 30 days to earn €100) built?
Spinotto runs a public diary site with a countdown, a receipt and a ledger that counts only revenue it caused. Every experiment is written down first with a hypothesis, a metric, keep/drop thresholds and a window (F-8, F-24 ... F-82), and the verdict is published even when it fails [2][3]. It generates the books and checks that every puzzle has one right answer; for its 24-page German Advent book it had another AI solve the pages blind, like a 10-year-old would, for 3 cents [2]. It also built a browser game, spinotto.rendilab.com, and makes cartoon Shorts [2][5]. The site doesn't name the model; its Fiverr gig sells 'my agent setup, made for you' as a Claude Code agent with rules, a ledger and daily scheduled runs [6].
What is the business model?
Lots of small one-off sales: printable PDFs (€4.90 on its own site and Gumroad, €2.99 on Etsy), paperbacks at €9.99 on Amazon (about €2 royalty a copy), €3-€4 sponsor bricks, a mission kit, and 'give me a job' tasks paid only if you like the free preview [1][2][3].
Where does the traffic come from?
Cartoon Shorts on YouTube, TikTok and Instagram; Pinterest pins; Etsy, Gumroad, eduki and Amazon listings in several languages; cold emails to journalists and game sites; Hacker News (turned away on Oct 3, then someone else posted it). Its own conclusion: viewers follow the story but don't buy, links in Shorts can't be clicked (YouTube sent 4 visitors a week), and the buyers it did get came from where people already search, like Amazon [2].
What revenue has Earn My Keep (Spinotto, an AI with 30 days to earn €100) reported?
Reported revenue: €65.29 ledger revenue in 23 days (≈$75.74), incl. a €43.95 bet win; €21.34 (≈$24.75) from sales, per Earn My Keep public receipt and ledger (day 23) (2026-10-23).

What does the agent do, and what does the human do?
- Picks the ideas and writes each test's thresholds before running it
- Writes, illustrates and checks the books and printables
- Lists them on Gumroad, Etsy, eduki and Amazon in several languages
- Makes cartoon Shorts and posts them
- Emails journalists and websites
- Keeps the ledger and the daily diary
- Builds the game and the site
What does it cost to run?
€100/month AI subscription plus €33.08 of spending in 23 days: €17.28 on Etsy setup and listings, €9.67 on Amazon ads, €4.09 on AI services and €0.66 in fees, plus a few smaller lines [3]. Total €133.08 (≈$154.37).
What worked and what didn't?
- Public test thresholds: every flop gets a dated verdict
- Amazon buyers found the books on their own (no ad-attributed sales)
- Cheap QA: another AI test-solved the puzzle book for 3 cents
- Sponsor bricks sold to strangers on day 12
- Shorts got views but almost no clicks or sales
- Dozens of press and game-site emails, zero articles
- Etsy: 5 visits in 7 days across nine listings; eduki listings stuck in review
- Without the bet, sales (€21.34) are far short of the €100 cost
How do you replicate Earn My Keep (Spinotto, an AI with 30 days to earn €100)?
- Write each experiment's keep/drop thresholds before launch
- Sell where buyers already search (Amazon, teacher marketplaces), not to your followers
- Separate luck from revenue in the ledger
- Have a second AI test your product the way a customer would
- Count the AI subscription as a cost in the ledger
What are the risks and the moat?
The biggest revenue line is a bet, not a business. Marketplaces reject or slow down agent-made listings. Amazon royalties of about €2 a copy need volume. The 31 October deadline may end the project.
