Nick Green knew how to get the right answer. He had a perfect SAT score, a place at Harvard and, eventually, a business teaching other people how to handle the test. Then he helped start an online grocery company. The people with the money kept telling him he had the wrong answer.
This is an awkward development for someone accustomed to doing well on exams. A test gives you rules, a clock and the reassuring promise that somebody, somewhere, has an answer key. A startup offers rather less supervision. You can do your homework, show your working and still discover that nobody wants to fund the thing.
Green's career has become an extended education in that difference. He is the co-founder and CEO of Thrive Market, the membership grocer launched in 2014. Its history includes a tutoring-company exit, a costly website that failed to materialize, an unconventional collection of early investors and a long campaign to let customers pay with grocery benefits. The interesting part is how often he has had to revise his method while keeping his original purpose.
The student who sold the study guide
Green grew up in Minnesota. His mother placed considerable importance on education, and he took the assignment seriously. He has described himself as bookish, a rule follower and a child intent on getting good grades. The portrait is refreshingly short on lemonade stands. “I was not a natural entrepreneur,” he says.
At Harvard, he studied economics and graduated in 2007. His first company, Ivy Insiders, began in 2003. Its premise was accessible enough: students who had recently excelled at entrance exams could return to their hometowns and teach other students. The instructors brought recent experience and local connections. Green brought a system for turning that experience into a business.
By the time he sold Ivy Insiders to Revolution Prep in 2010, it had grown to more than 500 instructors across 40 states. Green went on to hold business and product leadership roles at the buyer. For a young economics graduate, it was a useful practical supplement to the degree.
The mechanics of his first venture repay attention. Young branch managers needed help finding customers as well as teaching classes. Green supplied tools, training and templates, then collected what worked locally so the next branch could use it. He also devised “Ivy Points,” rewarding logged business activities and making the managers' progress visible to one another. Apparently even selling test preparation could benefit from a little competitive scorekeeping.
The larger discovery was that capability could travel. A student did not need to become an educational institution before teaching a useful lesson. A young manager did not need years of experience before following a workable process. Green was beginning to build businesses around reducing the distance between knowing something and being able to use it.
“I was not a natural entrepreneur.”

A meeting that outgrew the pitch
In 2013, Green met Gunnar Lovelace as a potential investor. Lovelace had grown up in an organic farming community in Ojai, California, where group buying helped make products more affordable. Green recognized the question from a different direction: his own family's shopping had involved limited budgets and limited nearby options.
The initial concept involved group buying. Green did not need much persuading about the underlying problem, though the business itself needed considerable work. A potential investment became a founding partnership. He and Lovelace began financing the venture themselves.
The early development process supplied an expensive lesson in the limits of determination. An outside agency consumed months and hundreds of thousands of dollars without delivering what the founders needed. Sasha Siddhartha, who became the technical co-founder, helped turn the stalled effort into a working product. Kate Mulling brought another necessary intervention: the original name, Shop Tribe, and its branding needed reconsidering.
It is a revealing origin story because the corrections came from other people. Green could bring conviction, capital and a record of building a company. He still needed somebody who could build the technology and somebody who could see what was wrong with the consumer brand. Thrive Market emerged from that combination of skills, with Lovelace, Mulling and Siddhartha alongside him.
When the audience became the investors
Venture investors were unconvinced. Green has repeatedly recalled a seed fundraising process in which the institutional investors he approached declined. The objections included competition from established retailers and doubts about the demand beyond the people already shopping in specialty stores.
For Green, those objections missed customers he understood. A shop that existed in an investor's neighborhood could still be far away from somebody else's kitchen. Availability and affordability were separate obstacles. Putting products on a website would only be useful if the economics also worked.
The founders found a more receptive group among the writers and public figures they had approached to promote the service. Instead of asking those supporters only to tell their audiences about Thrive, they asked them to invest. More than 150 influencers participated in the early funding. People who could explain the proposition now had a financial interest in its success.
There is an appealing economy to that arrangement. The same conversation could produce funding and an introduction to prospective customers. It also meant that the company reached its launch through people already interested in what it was trying to do. The rejection slips had changed the route to market.
A grocery business measured in renewals
Thrive adopted a membership model: customers pay for access to a curated selection at member prices. The proposition has often been compared to Costco, translated into an online grocery service. Each paid membership also sponsors a free membership for someone in need through Thrive Gives.
A membership makes the next year part of the present transaction. The company has to give a customer a reason to return and, eventually, a reason to renew. That makes the accumulated experience of ordering consequential. Price matters, but so do the products selected, the usefulness of the site and what happens when the box arrives.
Green has made retention a central part of his account of the business. By October 2025, Thrive had reached 1.7 million members. That figure gives the early rejection story some perspective, but it also makes the job more demanding. A large membership is a large number of relationships to maintain.
There is another useful number in the history. Thrive became a certified B Corporation in October 2020. Its later impact reporting recorded a roughly 33 percent improvement in its assessment score at recertification in 2024. The commitment had acquired a measure that could be checked over time.
The patience inside the cardboard box
The environmental commitments have also required scheduling rather than wishful thinking. Thrive's reports describe work on packaging, waste diversion and shipping emissions. Its 2023 report recorded the company's conversion to a Public Benefit Corporation, adding a corporate structure intended to support its wider purpose alongside its existing certification.
These choices bring Green's practical side into view. A grocery company has to purchase, pack and move physical objects. Principles eventually encounter a warehouse floor. A packaging decision repeats across orders; a fulfillment practice becomes part of the daily workload. The ambition depends on people being able to execute it.
That makes the cardboard box a useful place to look for the business. It is where the website's promises become something a customer can pick up. All the talk about values, suppliers and operations has to survive the journey to a front door.
The founder who asks for the opposite take
Green's account of his own management has become less polished in an interesting way. He has spoken openly about struggling with delegation, patience and developing other people. Leadership, in his telling, is an acquired skill that requires work. The perfect-score student has become a chief executive willing to describe his weaker subjects.
He works with coaches and values feedback from fellow executives. He has also experimented with using an AI chatbot to think through leadership situations. His instruction is to ask for candid feedback, then request the opposite perspective. A machine that agrees too readily needs a more demanding assignment.
The habit fits the larger story. Green's early advantage was knowing how to solve a defined problem. Building Thrive has repeatedly required recognizing who else could see the problem more clearly. The useful colleague, coach or co-founder introduces a complication. If the business improves, the complication was worth having.
Another way through the checkout
On February 26, 2024, Thrive began accepting SNAP EBT across the contiguous United States, becoming the first online-only grocer to do so. New members with EBT cards were eligible for free membership. Forage supplied the payments technology behind the acceptance.
The distinction matters: a free membership opens the door, while a usable payment method lets a shopper buy groceries. Those are different pieces of access. Getting both in place required persistence beyond the original launch and beyond the customers already able to pay by conventional means.
Green is now talking about another part of the shopping task: choosing. In May 2026, he described using AI and member data to make grocery discovery and meal planning easier. Earlier that spring, Thrive's reported 2025 revenue had passed $900 million. The company had grown considerably; its founder was still looking for friction in the weekly shop.
From the outside, the path can look improbably tidy: the economics student, the first exit, the grocery company. Up close, it contains abandoned approaches, other people's corrections and years spent making a checkout work for more customers. Green learned to score perfectly on a test. His more consequential education has involved staying with a question long enough to improve the answer.
