“I believe we can all agree gentrification is inevitable, with both positive and negative outcomes,” said Mr. Bokobza, whose company was founded in Israel in 2016. The company’s Bushwick expansion came after rapid growth in once-overlooked areas in other cities, including Tel Aviv and Berlin, where Mr. Bokobza saw an opportunity to create housing for renters priced out of the city center.

In most cases, the company signs long-term leases on existing buildings, renovates the interiors and then subleases the units to tenants, who get access to a number of amenities and a community event-planning app. Since arriving in Bushwick this year, the company has acquired 20 buildings within a half-square-mile radius, for a total of about 200 bedrooms, and Mr. Bokobza said there are another 30 buildings in the pipeline. While several of the units were vacant, others had leases that Venn took over; Mr. Bokobza said the company intends to raise those tenants’ rent by 3 to 5 percent on renewal.

For Clayton Sean Brown Jr., 22, a college student from Ohio who could no longer afford to pay $1,600 a month or more for student housing at New York University, moving to a $900 Venn apartment with three roommates made sense.

“I’m a person who doesn’t really have financial support from my parents,” said Mr. Brown, who works part-time at a gelato shop, adding that this is the cheapest rent he has had in New York.

But while Venn’s rents may be lower, critics say the units are too small for most families, promote high turnover and are too expensive for longtime residents. The median annual household income in Bushwick was $51,620 in 2017, about 17 percent lower than the citywide median, and almost a third of households spent more than half their income on rent, according to a census analysis by the New York University Furman Center.

“These buildings are still fundamentally often serving younger, whiter populations than those who have historically lived in the neighborhood,” said Emily Goldstein, a director at the Association for Neighborhood and Housing Development, a coalition of housing organizations.

Venn is undeterred. “This is our northern star: We will solve displacement,” said Chen Avni, the company’s chief experience officer. But there is a long way to go. About 40 percent of Venn’s Bushwick renters are not from New York — many are from the Midwest and Europe — and the median age is 24, Mr. Avni said.
