Can Entrepreneurs and Governments Team Up to Solve Big Problems?

Re: Mitchell B. Weiss

In 2017, Shield AI’s quadcopter, with no pilot and no flight plan, could clear a building and outpace human warfighters by almost five minutes. It was evidence that autonomous robots could help protect civilian and service member lives. But was it also evidence that Shield AI—a startup barely two years past founding—could ask their newest potential customer, the US government, for a large contract for a system of coordinated, exploring robots? Or would it scare them away? Harvard Business School professor Mitch Weiss and Brandon Tseng, Shield AI’s CGO and co-founder, discuss these and other challenges entrepreneurs face when working with the public sector, and how investing in new ideas can enable entrepreneurs and governments to join forces and solve big problems in the case, “Shield AI.” Open for comment; 0 Comments.

TikTok: Super App or Supernova?

Re: Jeffrey F. Rayport

TikTok’s parent company, ByteDance, was launched in 2012 around the simple idea of helping users entertain themselves on their smartphones while on the Beijing Subway. By May 2020, TikTok operated in 155 countries and had roughly 1 billion monthly active users, placing it in the top ranks of digital platforms globally. But the app had drawn the attention of competitors, regulators, and politicians, especially in the US, where commercial success was critical to its long-term enterprise value. Would TikTok become the first “Super App” with a global footprint, or did it run the risk of becoming a supernova that shone brightly only for a passing moment? Harvard Business School senior lecturer Jeffrey Rayport discusses these strategic challenges in his case, “TikTok in 2020: Super App or Supernova?” Open for comment; 0 Comments.

Why Did Pet Concierge Startup Baroo Fail?

Re: Thomas R. Eisenmann

In August 2017, Baroo Pet Care founder and CEO Lindsay Hyde wanted to continue expanding her pet services startup to new cities. In addition to raising venture capital, she needed to consider her growth strategy. Should she continue focusing on the needs of her early adopters or start tailoring Baroo’s services to more mainstream customers? And how fast is too fast to grow? Hyde (MBA 2014) joins Professor Tom Eisenmann to discuss how an early false positive signal from investors set an unsustainable course for her startup in the case, "Baroo: Pet Concierge," with additional lessons from Eisenmann’s 2021 book, Why Startups Fail: A New Roadmap for Entrepreneurial Success.
