Teams of Two and Hundreds of Agents

Matteo Franceschetti is the co-founder and CEO of Eight Sleep, the maker of temperature-controlled smart mattress covers that now sells in 35 countries, including China. He grew up in Ferrara, Italy, didn't speak English until he was 24, and practiced law at large firms in Milan before quitting to start a company. He co-founded Eight Sleep with his wife, Alexandra Zatarain, and Massimo Andreasi Bassi, a team he calls "three immigrants" with no Stanford or Harvard pedigree. The company went through Y Combinator, and he moved to China for 3 to 4 months after demo day to fix manufacturing. Eight Sleep now runs with about 160 people and a marketing budget in the hundreds of millions. These signals are from Matteo Franceschetti's interview with Harry Stebbings on 20VC.

1. Email With Zero People. Eight Sleep's email marketing channel brings in close to $100 million a year and has no human team. When the leader of the two-person team quit, co-founder Alexandra Zatarain built several AI bots in 3 days that took over the work. The bots plan the email calendar and use historical data to decide what to send and when. Franceschetti now counts "AI employees" alongside human ones, and by that measure Eight Sleep is 3 to 4 times bigger than its headcount.
2. Engineers Who Stopped Coding. Franceschetti says Eight Sleep's engineers stopped writing code about a year ago and now direct hundreds of AI engineers, mostly Claude. That is how a small team ships in 35 countries, many of them heavily regulated, across Europe, the Middle East and China. The monthly Claude bill is "still in the millions," below $5 million, and growing too fast for him to track. He expects AI to go from about 5% of engineering budgets toward 50% in usage while prices fall, so net spend should drop.
3. Teams of Two. Eight Sleep has about 160 employees, and Franceschetti says comparable companies at its revenue run closer to 1,000. Two people manage a paid media budget of $200 to $300 million, working from a daily report in which AI agents propose changes for them to approve or reject. Finance is 4 people where he'd expect 20, and a 6-month-old internal AI tools team builds the company's thousands of agents. His 3-year plan is 250 people producing $1 billion in revenue.
4. Your Own CAC Model. Eight Sleep ignores platform-reported acquisition cost; Franceschetti says Meta's number runs about 20% below the true CAC. Roughly every 6 months the team runs incrementality tests, switching off a channel such as Meta or TikTok in one state or region and comparing revenue against a similar one. Each channel starts with a small weekly budget and a CAC cap, then can spend as much as it wants while staying under the cap. Without your own model, he says, founders "just fool themselves."
5. One Channel at a Time. Franceschetti told a founder friend not to put $100,000 into every channel at once: start with Meta, prove it, then add the next. Growth teams always want to spend more, and a year of overspending forces a pullback that kills next year's growth rate. Eight Sleep could grow 50% faster this year by spending more. It sticks with immediate payback and healthy day-one contribution margin, a rule investor Keith Rabois pushed for from the start.
6. Word of Mouth at Scale. About 40% of Eight Sleep's revenue still comes from word of mouth, even at its current size. Annual subscription churn is in the low single digits, which Franceschetti says beats wearable companies heading to the public markets. TikTok didn't work for years, then started working 6 months ago once the company produced enough creator content. A truck with a bedroom built into the back now drives around Silicon Valley so people can try the product at home or at weekend events, and many buy on the spot.
7. China Comes Last. Chinese founders told Franceschetti they often launch consumer products abroad first, because Chinese buyers want brands the West already recognizes. Eight Sleep entered China after reaching 35 countries, sponsoring Ferrari driver Charles Leclerc and getting public mentions from Elon Musk and Mark Zuckerberg. Five years earlier, he says, a knockoff $500 cheaper would have destroyed it. Chinese consumers don't buy on websites, so the team relearned selling through super apps like WeChat and RedNote, and he calls China the hardest of the 35 markets.
8. Timing the Channel. Franceschetti treats retail and billboards as timing questions, since each works only once the brand meets certain conditions. An out-of-home campaign in the Middle East, a year after launch, failed where the same ad would have worked in New York. Eight Sleep tracks aided and unaided brand awareness to judge when a market is ready. He says retail was too early before and will become a meaningful channel over the next months and years.
9. Product First, Then Brand. "Great brand with a shitty product goes nowhere," Franceschetti says, and he thinks Silicon Valley builds great products and then underrates brand. He partly disagrees with Hugo Barra's rule that hardware must be either price king or feature king; Eight Sleep aims to be the best product and the most aspirational brand, so it can hold its price. He points to Steve Jobs, who often shipped 1 to 3 years after rivals and won on branding, packaging and pitch. On price, he describes today's product as the Model S of a lineup that will add cheaper models.
10. Two Rules for Athlete Deals. Every athlete deal needs two things: the athlete already uses the product, and Franceschetti gets a direct relationship without a manager in the middle. Leclerc had slept on Eight Sleep for 2 years before they met, and the deal closed within days of a dinner during the Miami Grand Prix; Leclerc also invested. Tadej Pogačar installed the product in his hotel every night of the Tour de France on his own, and his UAE team asked to partner. Franceschetti says about 80% of Formula 1 drivers sleep on it, mostly under confidential terms.
11. The Anthropic Red Flag. Franceschetti says hiring is back to 2021 levels, with pay for engineers and even product managers "out of control" and retention the harder problem. Eight Sleep increasingly hires in Europe and outside the US. A candidate who says they're in final rounds at Anthropic and Eight Sleep is "a really bad red flag," because the two jobs have nothing in common. When he promoted an internal engineer to VP of engineering after a 3-month trial against an external search, he told him to discuss it with his wife first and commit to 2 to 4 years.
12. Companies Become Holdings. Franceschetti expects AI to turn the best companies into holding companies, with tools built for one business revealing others, so "Eight Inc" might own 5 or 10 businesses. Xiaomi already makes phones, cars and appliances, and BYD sells components outside cars. He also thinks Chinese automakers should start building humanoid robots, which he expects to matter the way cars did in the 1960s. His furthest prediction: children born now will never work for money.
