Ben Pleat and the business of staying

Ben Pleat’s mother wanted to live in Manhattan. She got there. The building had the sort of shared spaces that make an apartment brochure easy to assemble, including a rooftop deck. Meeting the people who lived around her proved harder. For her son, that gap became a business question: what had the building actually provided, if it had supplied a place for neighbors to gather without helping them become neighbors?

That family experience runs through the story of Cobu, the company Pleat leads as CEO and co-founder. He had seen residential property from the investment side, where turnover creates work and expense. He had also seen it from a visitor’s position, watching someone outgoing struggle to find her people. A building could satisfy the checklist and still leave the introductions undone.

The problem suited a founder interested in both property and people. Apartments come with dimensions, rents and occupancy figures. Friendship declines to fit neatly into a spreadsheet. Pleat has spent years trying to make the two subjects intelligible to each other. A landlord needs a reason to buy the service. A resident needs a reason to open the app, then perhaps leave the apartment.

The skyline looked different from inside

Growing up near the Nassau-Queens border on Long Island, Pleat loved the approach to Manhattan. He has recalled getting goosebumps as the skyline appeared from the train. The attraction was there early: cities, buildings, the promise of being where things happened. Later, his work included acquisitions involving apartments and offices. From a distance, the city was thrilling. Up close, the experience inside a building became the more absorbing question.

At Harvard, he studied economics, led VentureWorks, the Harvard Ventures incubator, and helped launch the coding academy TAVtech. Work on WeWork’s growth team and in Goldman Sachs’ real estate private equity group exposed him to different ways of thinking about space and its customers. Those experiences sit together in his account of finding entrepreneurship: a curiosity about buildings, and an appetite for making something with a team.

By February 2017, he and Harvard classmate Steven Petteruti were developing Doorbell, the early project that preceded Cobu. Their research included conversations with more than 20 landlords and hundreds of residents. One early agreement involved a 483-unit building in Worcester, Massachusetts. The software offered a community feed, local discounts and ways to meet in person. The project was already being tested against the inconvenient habits of actual customers.

“A space is only as valuable as the people in it.”

The remark belongs to that undergraduate period, and gives his later work a useful starting point. A shared room offers possibility. Whether anyone feels comfortable using it is a separate design problem. The early Doorbell team treated face-to-face activities as part of the product. An empty lounge could be beautifully furnished and still have little to say for itself.

A potluck with no founder required

An early Cobu breakthrough involved a dinner the company had not organized. After meeting through its activities, residents arranged a potluck of their own. Dozens attended. Poker nights, board games and dinners with local chefs had helped introduce people. Now residents were making plans themselves.

For a business selling community, there is something pleasing about the moment the customer stops waiting for instructions. A potluck distributes responsibility rather efficiently: someone brings food, someone brings more food, and someone discovers that arranging dinner need not require a professional events department. The significant detail was who had taken the initiative. The residents were carrying the next gathering forward.

That distinction also appears in the product’s development. Beginning in 2019, Cobu worked with engineering partner Ars Futura on a redesigned home page and tools for finding and arranging gatherings. Small groups could form around interests such as running, dogs or books. Discussions could happen within a group or across the building. Notifications linked people to the relevant conversation, rather than depositing them at the front door of the software.

These are modest pieces of interface design with quite specific jobs. Someone looking for a running partner has a different immediate need from someone seeking an announcement for the entire property. A useful product has to accommodate both without demanding that every neighbor enjoy the same evening. The party can be optional. Finding the people who share your interests should be easier.

Almost 100 ways to hear no

The idea’s personal meaning did not make fundraising straightforward. Pleat recalled that nearly 100 firms declined a funding request in 2018. He described responding by concentrating on the product and the value it delivered. By February 2021, he was reporting more than 30,000 apartment homes on Cobu, operating across more than 43 cities in the United States and Canada.

Those figures belong to that stage of the company. They show the distance from the undergraduate experiments without pretending to describe today’s footprint. They also give the rejection story a little proportion. A passed investment meeting and a resident using the service are different kinds of feedback. A founder must decide how much weight to give each.

Other investors did come aboard. In September 2019, Jo Tango announced an investment after an introduction from Bob Preble, formerly Bit9’s first vice president of engineering. Tango singled out Pleat’s resilience. The connection is a small example of the work behind an apparently solitary founder story: introductions, mutual acquaintances and people willing to make a judgment about someone else’s persistence.

The current leadership includes Steve McLaughlin as co-founder and COO. Pleat’s own description of choosing a co-founder puts trust and integrity first, alongside complementary abilities and perseverance. His advice to students considering a company is similarly direct: “No great company has ever been built on a whiteboard.” For someone building a business around introductions, talking to people is a suitably literal operating principle.

His listening and reading interests offer another angle on the founder. He has discussed enjoying Masters of Scale and How I Built This, including the latter’s carefully produced storytelling. He and investor Sal Daher also discussed Edward Glaeser’s Triumph of the City; Glaeser was an adviser to Cobu. Cities and the people who build businesses recur in his choices. One subject supplies the setting, the other a collection of attempts to understand how an idea becomes an organization. An apartment company needs people who can understand both the address and the enterprise.

Forbes’ Boston 30 Under 30 Local list included him in 2023. Recognition supplies a neat milestone. The more revealing continuity is the question that survives it: what would make the experience of living in an apartment better enough that someone would choose to remain?

The resident who already has the keys

By 2025, Pleat was making a pointed argument about the industry’s priorities. He questioned whether spending and staffing matched its professed interest in retention. Recruiting the next resident absorbs attention. Serving the current one must compete for it. His proposed change began with delivering the experience a property promises and giving residents ways to develop connections.

He offered a concrete example near Dallas: residents using Cobu arranged repeated pickleball games, which developed into a league. The owner was then considering investment in a facility. Participation had supplied information about what people wanted. There is an agreeable reversal here. The residents’ enthusiasm arrived before the capital improvement.

He also acknowledged the limits of retention. People change jobs, buy homes or need more space. Community cannot settle every housing decision. His argument concerns the choices an operator can influence, starting with responsiveness and an experience that lives up to the advertising. The distinction keeps the pitch within the territory where a property team can actually work.

The next search starts with a neighbor

The company’s newer work carries that activity beyond the existing resident population. On The Apartment Department in December 2025, Pleat discussed resident-generated content, property marketing and the growing role of AI in search. The experiences that make a place interesting to its occupants can also help someone considering a move understand it.

By February 2026, Pleat was writing about ways for renters to evaluate community participation before signing a lease. Events, groups and other resident activity could offer evidence of everyday life. The proposal is easy to grasp: a photograph of the lounge tells you what it looks like; information about participation offers another way to assess it.

Today the business presents itself as CobuAI, connecting its community work with AI visibility and leasing. It argues that fresh, specific accounts of resident life can help properties appear in AI-assisted apartment searches. That is the company’s commercial thesis, rather than a universal rule about search engines. Pleat is extending the use of the activity his company has spent years helping generate.

Distribution has changed too. On March 5, 2026, Entrata announced that Cobu would be embedded in Homebody, its resident app, with managed community engagement. In that announcement, Pleat emphasized meeting residents inside an app they already use. It is a practical consideration for any founder selling another place to log in: a useful conversation has a better chance when people know where to find it.

The business now reaches from an introduction between neighbors to the information a prospective resident might encounter before moving. The route has included a classroom project, game nights, funding rejections, product development and new partners. At its center remains Pleat’s original interest in what happens inside a building after the skyline has done its work. A city can catch your eye from the train. Choosing to stay asks something more of the address.
