    Entrepreneurship as Experimentation

    By: William R. Kerr, Ramana Nanda and Matthew Rhodes-Kropf

    Entrepreneurship research is on the rise, but many questions about its fundamental nature still exist. We argue that entrepreneurship is about experimentation: the probabilities of success are low, extremely skewed, and unknowable until an investment is made. At a macro level, experimentation by new firms underlies the Schumpeterian notion of creative destruction. However, at a micro level, investment and continuation decisions are not always made in a competitive Darwinian contest. Instead, a few investors make decisions that are impacted by incentive, agency, and coordination problems, often before a new idea even has a chance to compete in a market. We contend that costs and constraints on the ability to experiment alter the type of organizational form surrounding innovation and influence when innovation is more likely to occur. These factors not only govern how much experimentation is undertaken in the economy, but also the trajectory of experimentation, with potentially very deep economic consequences.

    Andreessen Horowitz

    By: Thomas R. Eisenmann and Liz Kind

    Andreessen Horowitz (a16z), a venture capital firm launched in 2009, has quickly broken into the VC industry's top ranks, in terms of its ability to invest in Silicon Valley's most promising startups. The case recounts the firm's history; describes its co-founders' motivations and their strategy for disrupting an industry in the midst of dramatic structural change; and asks whether a16z's success to date has been due to its novel organization structure. a16z's 22 investment professionals are supported by 43 recruiting and marketing specialists—an "operating team" that is an order of magnitude larger than that of any other VC firm. Furthermore, the operating team aims to not only assist a16z portfolio companies, but also to be broadly helpful to all parties in the Silicon Valley ecosystem, including search firms, journalists, PR agencies, and Fortune 500 executives. The bet: by providing "no-strings-attached" help to ecosystem partners, the partners might someday reciprocate by steering founders seeking funding to a16z. The case closes by asking whether a16z should seek to double its scale over the next years.

    Raising Startup Capital

    By: Jeffrey Bussgang

    Entrepreneurs typically focus their full energies on business-building. But raising capital is a core part of building a valuable business. Developing expertise in raising capital is more than a necessary evil, it is a competitive weapon. Master it and you will be in a better position to make your company a massive success. But how do you finance a new venture? In this note, I will try to help answer this question by addressing the following topics: Types of funding. The two major types of startup capital are equity funding and debt funding although there are a few hybrid flavors as well. Sources of funding. These include venture capital firms, angel investors, crowd-funding, and accelerators/incubators. What investors look for. Each source has a different funding process and set of criteria which you need to understand before seeking funding from that source. The mechanics of equity funding. Seeking and securing funding involves setting amounts, agreeing to terms, and defining relationships.

    The Consequences of Entrepreneurial Finance: Evidence from Angel Financings

    By: William R. Kerr, Josh Lerner and Antoinette Schoar

    This paper documents that ventures that are funded by two successful angel groups experience superior outcomes to rejected ventures: they have improved survival, exits, employment, patenting, web traffic, and financing. We use strong discontinuities in angel funding behavior over small changes in their collective interest levels to implement a regression discontinuity approach. We confirm the positive effects for venture operations, with qualitative support for a higher likelihood of successful exits. On the other hand, there is no difference in access to additional financing around the discontinuity. This might suggest that financing is not a central input of angel groups.

    The Ullens Center for Contemporary Art

    By: Mukti Khaire and Nancy Hua Dai

    Since its opening in Beijing in November 2007 as the first non-profit art center in China, UCCA had been operating with the mission to "promote the continued development of the Chinese art scene, foster international exchange, and showcase the latest in art and culture to hundreds of thousands of visitors each year." For the past six years, UCCA had worked with more than 100 artists and designers to present 87 art exhibitions and 1,826 public programs to over 1.8 million visitors, including many important leaders from all over the world. Given the context of the economic and political environment in the rapidly changing Chinese art market, the founders and senior management of UCCA wondered what they could do to achieve growth and financial viability while continuing to realize their mission.

    The Promise of Microfinance and Women's Empowerment: What Does the Evidence Say?

    By: Dina D. Pomeranz

    The microfinance revolution has transformed access to financial services for low-income populations worldwide. As a result, it has become one of the most talked-about innovations in global development in recent decades. However, its expansion has not been without controversy. While many hailed it as a way to end world poverty and promote female empowerment, others condemned it as a disaster for the poor. Female empowerment has often been seen as one of the key promises of the industry. In part, this is based on the fact that more than 80% of its poorest clients, i.e., those who live on less than $1.25/day, are women. This paper discusses what we have learned so far about the potential and limits of microfinance and how insights from research and practice can help inform the industry's current products, policies and future developments.

Entrepreneurship
Social Enterprise

Our long tradition of research in Entrepreneurship goes back to the 1930's and 1940's with the “the father of venture capitalism,” General Georges Doriot, and Joseph Schumpeter’s theory of innovation as a process of “creative destruction.” Building on our intellectual roots, our scholars come from disciplines including economics, finance, sociology, strategy, business history, management, and social entrepreneurship. A number of our faculty come from practice as venture capitalists and start-up founders. We focus our research on the identification and pursuit of entrepreneurial opportunities; domestic and international funding of entrepreneurial endeavors; innovation, particularly technological innovation in international ventures; the environments in which entrepreneurs make decisions; and social entrepreneurship. As our research contributes new insights, we are advancing the world’s understanding of complex entrepreneurial issues and helping to increase the entrepreneurial success of our students and practitioners worldwide.

Measuring the Impact of Impact Measurement

By: Emanuele Colonnelli, Tim Mcquade, Natalia Rigol and Benjamin N. Roth
  • 2026 |
  • Working Paper |
  • Faculty Research
Impact measurement is central to impact investing and social entrepreneurship, yet little is known about whether firms benefit privately from measuring impact. We conduct the first randomized controlled trial of an impact measurement intervention among high-growth social enterprises in India. Treated firms exhibit nearly twice as much revenue growth and raise nearly twice as much capital as control firms. In a companion experiment with early-stage investors, we find that investors respond strongly to quantified impact metrics but not to generic qualitative impact statements. Together, our results show that impact measurement can shape firm growth and capital allocation.

How AI Helps the Best and Hurts the Rest

  • Article |
  • MIT Sloan Management Review
Can generative AI serve as an on-demand business adviser? A field experiment with hundreds of small business owners in Kenya found that AI access boosted revenues and profits by 15% for high performers — but caused a nearly 10% decline for those who had already been struggling. The culprit: Weaker performers followed generic or misleading AI advice because they lacked the judgment to filter it out. Leaders deploying AI at scale must design their rollouts carefully to avoid widening performance gaps.

Chobani: Growing a Live and Active Culture In-Class Multimedia Case

By: Joshua D. Margolis, Ruth Page and Matthew Preble
  • May 2026 |
  • Case |
  • Faculty Research
Pre-abstract: In-class multimedia cases are designed to unfold in the classroom. The student-facing Prep for In-Class Case should be assigned to students before class. The instructor-facing In-Class Multimedia Case should be used by the instructor in class to facilitate discussion. Some in-class cases include Additional Materials, which can be used in class or shared with students after class. Some cases have instructor-facing Case Updates, which typically contain case reveals. Abstract: Hamdi Ulukaya, CEO of the Greek yogurt company Chobani, Inc., was reflecting on what explained his young company's meteoric rise. The company held over half of the U.S. Greek yogurt market, and nearly 20% of the total yogurt market. The company's innovative approach to product design, sales, marketing, and communication had made its yogurt a hit with consumers, and its entrepreneurial and innovative culture made it popular with its employees. But by 2012, major food companies, such as General Mills and Groupe Danone among others, were beginning to aggressively promote their Greek yogurt. In addition, Chobani was rolling out innovative new products, and had to determine how to enter new markets. At the same time, Ulukaya was also focused on preserving the company's unique culture and approach to work as it grew.

The Declining Local Bias of Entrepreneurship in the United States

By: Innessa Colaiacovo, Margaret Dalton, Sari Pekkala Kerr and William R. Kerr
  • May 2026 |
  • Article |
  • AEA Papers and Proceedings
Multiple studies document a local bias of entrepreneurship (LBE) in recent decades, where self-employed entrepreneurs are systematically more likely than wage workers to operate in their region of birth. This paper documents an important new fact: the LBE has been declining in the United States since 1970. The LBE is still present for white men engaged in self-employment, but it no longer exists for the overall U.S.-born workforce. We connect that decline to the transformation of self-employment away from high startup- capital sectors and the reduced opportunity for local self-employed entrepreneurs to achieve high incomes compared to wage work.

Team Gender Composition and Firm Performance: Experimental Evidence from Solar Entrepreneurs in Rwanda

By: Rowan Clarke, F. Christopher Eaglin, Manuel Barron and Martine Visser
  • 2026 |
  • Working Paper |
  • Faculty Research
How does team gender composition affect the performance of small technology-enabled firms in the Global South? We study this question using a field experiment with 270 village-level solar enterprises in rural Rwanda, where teams of four entrepreneurs were randomly assigned to be all-male, all-female, or mixed-gender. Over 18 months, mixed-gender teams underperform all-male teams by approximately 40%, while all-female teams also underperform all-male teams by 24%, with point estimates placing all-female teams between the all-male and mixed arms. To probe mechanisms, we pair the 18-month administrative output data with minute-level GSM timestamp data over the first six months. Mixed teams generate fewer recharges during evening peak-demand hours, while all-female teams do not exhibit the peak-hour coordination deficit. Despite lower business revenues, all-female teams generate distinctive householdlevel spillovers, with children studying approximately 74 additional minutes per week. Our findings suggest that performance in small entrepreneurial firms depends critically on whether teams can organize around conflicting and often binding temporal constraints.

In 2025, Naren Shaam, founder and CEO of Omio, a Berlin-based multimodal travel platform, must decide how to steer the company’s next phase of growth. After rebounding from the COVID-19 collapse to reach profitability and over one billion users annually, Omio faces three strategic paths: deepening its profitable European base, expanding into emerging global markets, or investing heavily in artificial intelligence to redefine the travel experience. The case traces Omio’s journey from startup to global platform and challenges students to evaluate how Shaam should balance growth, profitability, and technological innovation in the rapidly evolving travel-tech landscape.

Mapping AI into Production: A Field Experiment on Firm Performance

By: Hyunjin Kim, Dahyeon Kim and Rembrand Koning
  • 2026 |
  • Working Paper |
  • Faculty Research
AI can deliver productivity gains on individual tasks, yet evidence on whether these gains aggregate to firm performance remains limited. We study a central friction in AI adoption, which we call the mapping problem: discovering where and how AI creates value within a firm's production process. Across 515 high-growth startups, we run a field experiment in which treated firms receive information about how other firms have reorganized production around AI, prompting them to search for use cases across a broader set of firm functions. We find that treated firms discover more AI use cases, a 44% increase, concentrated in product development and strategy. These changes result in economically meaningful performance gains. Treated firms complete 12% more tasks, are 18% more likely to acquire paying customers, and generate 1.9x higher revenue. Revenue and investment gains are largest at the 90th percentile and above, consistent with AI expanding the upper range of what firms achieve rather than modestly improving marginal ventures. Despite faster growth, treated firms do not scale inputs proportionally. Their demand for external capital investment falls by 39.5% relative to the control group, while their demand for labor remains unchanged. These results provide causal evidence that AI improves firm performance and productivity even at its current capabilities, and that discovering where and how to deploy AI is a key bottleneck in realizing the gains from this technology.

Sunand Menon: The Making of an AI Leader (A)

By: Linda A. Hill and Lydia Begag
  • March 2026 (Revised June 2026) |
  • Case |
  • Faculty Research
In December 2025, Sunand Menon, an Operating Partner at biotechnology venture capital firm Flagship Pioneering and newly appointed Chairman of Flagship’s portfolio company CIBO Technologies, faces a pivotal career decision. After conducting an intensive review of CIBO at the request of one of its co-founders and outgoing Chairman, Menon is unexpectedly asked to step in as acting CEO and lead the company’s growth strategy. The opportunity fits a three-decade pattern of “leaps” across industries—from consumer goods and engineering to financial services and media to industrials, technology, life sciences, and now agriculture—animated by Menon’s belief in curiosity, comfort with change, and continuous learning. Yet Menon has never served as a CEO before, and taking on the leadership role in the ag-tech space, unfamiliar territory, makes him feel both “nervous and excited.” As Menon reflects on his non-linear career journey, he must decide whether to take on the “completely different job” of leading CIBO through its next phase of transformation or focus instead on scaling strategic relationships and AI ventures at Flagship—and, more broadly, consider what the optimal role of the human leader should be in an increasingly AI-informed world.

ŌURA 2025

By: Thomas R. Eisenmann and George Gonzalez
  • March 2026 (Revised April 2026) |
  • Case |
  • Faculty Research
In September 2025, Tom Hale, ŌURA’s CEO, faces a classic “where to play, how to win” inflection point: the Oura Ring has become a breakout consumer health wearable—profitable, scaling fast, and valued at $5.2B post-money, backed by $770M in venture capital. With roughly $500M of revenue in 2024, growth has been propelled by women’s-health use cases and reimbursement tailwinds. But Hale is now wrestling with what his next strategic move should be. He can keep driving ŌURA’s proven go-to-market engine for consumer sales, or he can push hard into regulated healthcare, where clinical validation and payer/provider partnerships could unlock a much larger market—but at the cost of longer cycles, new capabilities, and an operating model that risks slowing (or pulling resources from) the core. Hale has to decide how bold ŌURA should be and what sequencing, go-to-market strategy, and resource allocation would enable him to capture the healthcare upside without breaking the speed, focus, and repeatability that made the company successful in its consumer markets.
