Start with the number, because it is larger than almost anyone guesses.
Immigrants have founded or co-founded 59% of America's privately held companies valued at $1 billion or more — 455 of 775, according to the National Foundation for American Policy's June 2026 analysis, up from 55% in its 2018 and 2022 reports. Broaden it to include the children of immigrants and it reaches roughly two thirds. Nearly 80% of US unicorns have an immigrant founder or an immigrant in a key leadership role. And 24% — almost one in four — have a founder who originally came to the United States as an international student.
The collective value of immigrant-founded unicorns rose from $168 billion in 2018 to about $5.0 trillion by 2026. The countries of origin are led by India with 96 such companies, then Israel with 60, the United Kingdom with 47, China with 41, Canada with 30, Russia with 23, France with 21, Germany with 18 and Ukraine with 16.
Those numbers are usually deployed in immigration-policy arguments. We are interested in something narrower and more practical: what has to physically happen for a twenty-six-year-old who lands at SFO from Bangalore or São Paulo or Lagos to end up co-founding something. Because the honest answer involves a lot of unglamorous logistics, and the first one is a place to sleep.
Diversity of thought is a mechanism, not a value statement
The phrase "diversity of thought" has been worn smooth by corporate use, so it is worth restating what it actually does in the specific context of a founder house.
Early-stage company building is the search for a true belief that other people do not hold yet. Every advantage comes from knowing something the market has not priced. And the most reliable source of such knowledge is not intelligence — it is having lived somewhere else, in a different system, with different defaults.
A founder who grew up with Brazilian instant payments has priced-in intuitions about money movement that a US-raised founder has to learn deliberately. Someone who ran logistics in Lagos knows failure modes no textbook lists. A founder from a country where WhatsApp is the operating system of commerce sees product surfaces an American founder does not. Put those four people around one kitchen table every night for four months and the collision rate between non-overlapping knowledge bases is high — which is precisely the condition under which new ideas get formed.
This connects directly to the research on proximity. The 2023 Nature study by Lin, Frey and Wu found that remote collaboration produces fewer breakthrough ideas, specifically because distributed teams are less likely to combine their knowledge on conceptual work where knowledge is tacit. Tacit knowledge is exactly what a person's background consists of. It is the hardest kind to transmit over video and the easiest to transmit over dinner.
So a mixed house is not an ethical accessory to a founder residency. It is the part that makes the format worth more than a co-working membership.
The mobility evidence
There is also a serious body of work on what happens to people's outcomes when their friendships cross social lines.
Raj Chetty and colleagues, publishing in Nature in 2022 from an analysis of billions of Facebook friendships, found that economic connectedness — the degree to which people from lower-income backgrounds form friendships with people from higher-income backgrounds — is among the strongest known predictors of upward income mobility. Communities where low- and high-socioeconomic-status people mix less show less upward mobility between generations. Their estimates suggest that children from low-income families would see adult incomes roughly 20% higher if they grew up in places with the connectedness typical of high-income children's environments.
The mechanism is not charity or inspiration. It is information and access: which jobs exist, how a term sheet works, what to say in a meeting, who to email, what is normal to ask for. These things travel through friendships, not institutions.
A founder house is a dense, high-intensity connectedness environment, and the demographics of who shows up are unusual. In our own homes we have hosted founders and operators from Y Combinator, Hexa, Stanford's Mayfield Fellows Program, Latitud and General Catalyst-backed companies, from many countries and across a wide range of industries. A twenty-three-year-old who has never met a venture investor, living for three months with a second-time founder who has raised twice, is receiving an education that no program sells and no amount of money buys directly.
That is the social mobility claim, and it is a modest one: the house transmits the tacit knowledge of how the system works to people who did not grow up inside it.
The part nobody budgets for: you cannot rent an apartment
Here is where the policy numbers meet the operational reality, and where a lot of promising arrivals quietly fail.
A standard San Francisco lease asks for US credit history, US income verification, references from prior US landlords, and frequently several months up front. A founder who arrived three weeks ago on a visa has none of those, regardless of how much money is in the company's bank account or how good the company is. Add the market conditions — median one-bedroom rents around $4,180, two-bedrooms at $6,020, active listings down roughly 30% year over year, vacancy near 3% in the neighbourhoods people want — and the result is that the best-qualified candidate on paper is often the least rentable tenant in the room.
So the practical obstacles facing an international founder in their first ninety days look like this:
- No US credit file, so conventional applications are declined or require large deposits.
- No furniture, and no reason to buy any for a stay of unknown length.
- Utility and internet accounts that require identification and time — internet installation alone can run one to three weeks.
- A lease term four times longer than the certainty they have about being here.
- Arrival into a city where they know, often, nobody at all.
The last one is not a logistics problem. It is the one that determines whether they are still here in a year. Isolation in an expensive studio is the most common quiet failure mode for a founder who has moved continents, and the research above explains why: the thing they moved for was the network, and a studio does not contain one.
What a well-mixed house requires from an operator
We will be concrete, because "diverse community" is easy to claim and harder to run.
Make entry possible without a US financial history. Month-to-month terms, one all-inclusive monthly price, and a qualification process built for someone who landed last week. If the only people who can book are people with two years of US pay stubs, the house will be demographically narrow whatever the marketing says.
Do not sort people by price into separate buildings. A house where a first-time twenty-two-year-old founder and a forty-year-old repeat founder share a kitchen produces the connectedness effect. Two buildings sorted by budget produce two monocultures.
Build for common life, not just occupancy. The kitchen, the big table and the living room are where the value is created. Bedrooms are where people sleep. An operator optimising purely for beds per square foot is destroying the asset.
Be a short, honest path in. 30-night minimum rather than a year. Rent, utilities, internet and cleaning in one number. Internet live on arrival. Nothing to assemble. That is the whole of what we mean by removing friction: a founder's first week in San Francisco should be spent meeting people, not at a furniture warehouse.
That is the design brief hyperstay works to — furnished homes across San Francisco, private rooms or an entire house with six or more bedrooms, 30-night minimum, all-inclusive monthly pricing, and the kind of mixed house where the person across the table did not grow up where you did.
Fifty-nine percent of America's billion-dollar companies were founded by people who came from somewhere else. They all needed a bed on their first night. It is not the whole of the story, but nothing else in it happens first.
