Elliot Cohen and the art of making yourself less necessary

In December 2015, a message arrived at the University of Massachusetts Boston’s Venture Development Center. Bill Aulet, who ran MIT’s Martin Trust Center for Entrepreneurship, wanted help for a friend. The friend was Elliot Cohen. A key member of Cohen’s team faced an immigration hurdle, and the young company could ill afford to lose her. Over breakfast at Cambridge’s Crema Cafe, Cohen explained the problem to the center’s William Brah.

This is an unusually useful place to begin a founder’s story. There is no funding announcement, no theatrical unveiling, no graph ascending toward the heavens. There is a colleague whose work matters, a founder who needs help, and someone who knows whom to ask. A business has become large enough to encounter a problem that cannot be fixed by editing its software.

Cohen was building PillPack with TJ Parker. Years later, the pair would be building again, this time with Ashwin Muralidharan at General Medicine. Cohen is now that company’s President. Between the two ventures sits an Amazon acquisition and several years inside the company that bought them. Yet the breakfast meeting captures something a transaction history misses: Cohen’s career has repeatedly involved assembling the people and conditions that allow work to happen.

The organizer becomes the founder

At the University of California, Berkeley, Cohen studied computer science and cognitive science. He also organized concerts and events. He has described moving between undergraduate research and activities with little apparent connection to technology. A person arranging a concert and a person writing software might seem to be preparing for different careers. Both, however, have to discover where a plan meets resistance.

A concert has an audience. Software has users. Neither is much impressed by an explanation of how difficult the arrangements were. Cohen later connected his event organizing to the work of putting teams together. That is a more interesting account of an engineer’s education than a list of programming languages: part analytical training, part getting people to do something together.

After university came a couple of years at Microsoft, followed by work in smaller, early-stage companies. He eventually arrived at MIT’s Trust Center in 2010 to run its entrepreneur-in-residence program. Before enrolling as an MBA student, he was helping organize the experience of entrepreneurship for other people.

The order matters. A university can appear in a founder’s biography as a credential collected on the way to the real story. In Cohen’s case it was also a workplace, a gathering place and a set of relationships. He decided to pursue an MBA at Sloan after working with its people. The institution became persuasive through use.

He helped create Hacking Medicine with Zen Chu and others in MIT’s entrepreneurship community. The program brought people from different disciplines together to work on problems. In describing its philosophy, Cohen emphasized encounters among people who would ordinarily have little reason to speak to one another. The room itself was part of the work.

There were connections beyond the hackathons, too. Cohen helped set up Linked Data Ventures with Sir Tim Berners-Lee. MIT’s award records list him alongside Allen Cheng and Allison Yost for Hacking Medicine in 2013. These are glimpses of someone contributing to the machinery of a community while beginning to find his own place in it.

He met Parker through MIT’s entrepreneurship activities, including the $100K competition. In 2012, the pair won a Hacking Medicine hackathon. Cohen earned his Sloan MBA in 2013, the year they co-founded PillPack. The organizer had become a participant in the experiment he helped make possible.

The person behind the system

A teaching case about the young company begins with Cohen preparing pour-over coffee in its Somerville office. Parker watches and considers how quickly the business has developed. It is an ordinary office scene, made memorable by the patience of the coffee preparation beside the speed of the company’s progress.

There is no need to turn a beverage into a personality test. The detail earns its place because it lets the founders occupy an actual room. They have a working day to get through. Their company has customers and financing, but it also has an enormous amount left to figure out. Success has added to the list.

Cohen’s early role combined product and operations. He described working closely with the operating team to understand its processes and build useful tools. The distinction between a digital product and the work required to deliver it was difficult to preserve in such a business. A screen could make a promise; people and systems had to keep it.

That helps explain the appeal of his more humble recollections. In a 2025 conversation with investor Julie Yoo, he discussed early work involving CSV files and cake boxes. A spreadsheet format and packaging borrowed from another trade are splendidly awkward companions for an acquisition story. They remind us that the beginning had materials, workarounds and unfinished edges.

Prototypes also force a business to confront details that a pitch can skate past. Someone must decide what goes where, which information survives a handoff and whether the whole arrangement works for the person receiving it. The cake box is useful precisely because it is a thing that has to be handled.

PillPack’s official biography described Cohen’s responsibility in terms of the systems needed for operational scale. The glamorous version of entrepreneurship tends to give the idea most of the credit. His job description makes room for the recurring work: constructing a company that can do tomorrow what it managed to do today, with more people depending on it.

A question travels further

One of Cohen’s clearest comments about management concerns ownership. He credits Aulet’s approach at MIT: ask questions that bring attention to the central problem, then allow people to determine how to solve it. Cohen adopted that approach with his own team. His phrase is compact enough to fit on a meeting agenda: “ultimately I encourage ownership”.

There is a demanding idea inside those four words. Ownership requires a manager to tolerate an answer that did not originate with the manager. It also requires the person doing the work to have enough context to choose well. Simply withdrawing instructions leaves a vacuum. Asking a useful question gives someone something to work with.

“Ultimately I encourage ownership.”

Elliot Cohen, on leading his team

For a growing company, this becomes a practical problem of capacity. If every decision must visit the founder’s desk, the business acquires a very expensive waiting room. More employees can mean a longer queue. A leader who helps other people reason through decisions gives the organization a chance to move without constant personal intervention.

Experienced colleagues matter to that arrangement. In its reflection on PillPack’s sale, Founder Collective singled out the founders’ willingness to bring in leaders with skills the company needed. Geoff Swindle joined with direct marketing experience. Yvonne Hao brought operating and financial experience. The team changed as the demands on the business changed.

Hiring people with that depth asks something of founders, too. They have to make room for expertise rather than treat every new hire as an extra pair of hands. A company’s organization determines which problems anyone can see, which problems anyone can solve, and how far a good decision can travel before somebody stops it.

The Crema Cafe meeting belongs here. Its subject was a person building a system the company needed. Keeping that person on the team required Cohen to draw on relationships outside it. The same community that had helped him become a founder could be approached when founding produced an unforeseen difficulty. Networks have rather more substance when there is actual work at stake.

Back to the starting line

Amazon acquired PillPack in 2018. Investor George Zachary later recalled meeting Parker and Cohen on a Monday in May 2015 and reaching an agreement by Thursday. Fred Destin remembered an earlier coffee with the pair at Cambridge’s Voltage in 2013. Different backers, different dates, more coffee. The company’s history contains a surprising number of tables around which people decided to work together.

The acquisition did not immediately end the founders’ operating careers. They stayed at Amazon, then left in September 2022. In 2023, Cohen, Parker and Muralidharan founded General Medicine. The company launched nationwide in May 2025. A longstanding partnership had become part of another founding team.

On October 6, 2026, General Medicine announced a $120 million Series B led by Andreessen Horowitz, bringing its total funding to $152 million. The announcement identified Parker as CEO, Muralidharan as Chief Product Officer and Cohen as President. Those figures belong to the company; the more revealing personal detail is Cohen’s decision to keep building.

He has also kept a connection to the classroom. MIT Sloan lists him as a senior lecturer, and the Trust Center identifies his course as Scaling Entrepreneurial Ventures. There is a pleasing continuity in that assignment. Cohen once helped run an entrepreneurship program, then became an MBA student, then built a company, and now teaches the difficulty of making a venture larger.

Teaching offers another kind of scale: experience has to become useful to people who were absent when it was acquired. A founder’s recollection needs enough detail to help someone else make a decision, rather than merely persuade them to admire the outcome. Coffee, cake boxes, new colleagues and an unexpected breakfast request all have a place in that account.

Cohen’s public record shows a career spent moving between building organizations and helping others build them. The next company will supply its own complications. He brings a habit worth watching: ask the question, find the person who can help, and give people room to own the answer. Then get back to work.
