Caltech Student Start-Ups Dive Into the “Shark Tank” in Bill Gross Business Plan Competition

At the inaugural Bill Gross Business Plan Competition, aspiring entrepreneurs pitched start-up ideas to a panel of seasoned investors. In this version of Shark Tank, each team was made up of Caltech undergraduate and graduate students armed with scientific expertise and a vision of how next-generation technology will improve the world.

Fifteen student teams—selected as finalists from 80 total applications—presented their business plans in a day-long event in April to compete for the Bill Gross Prize for Entrepreneurship. The first-place winner would walk away with $30,000, second place with $25,000, and third with $15,000, drawn from a $100,000 prize donation by entrepreneur and Caltech Trustee Bill Gross (BS ’81). Little did students know that all teams would be winners that day. A surprise $100,000 matching donation from private capital firm Sunstone-ALC, combined with Gross’s donation, enabled a $10,000 award to each of the twelve runner-up teams.

A start-up evangelist who has launched multiple companies, Gross taught a science and technology entrepreneurship class at Caltech last fall and is passionate about helping Caltech students bring their ideas to fruition. “Our hope is that with winning this Caltech event, other investors will join you to make your dreams possible,” Gross said at the beginning of the competition.

During the event, each student team had five minutes to pitch their start-up ideas to the three judges: Ajay Kshatriya, partner at Wilson Hill Ventures, a venture capital fund that invests exclusively in Caltech startups; Amanda Cashin (PhD ’06), an advisor at Wilson Hill Ventures; and Dave Licata, president and CFO of TORL BioTherapeutics and executive chairman of 1200 Pharma. Sectors encompassed by the business plans included health care technology, AI tools, sustainability solutions, and more. Groups were judged on the quality of their team dynamic, market opportunity for their company, and differentiation of their technology.

The “elevator pitch” format challenged participants to focus their ideas on the fundamentals., a start-up idea hatched in Gross’s Caltech class by graduate student Aditya Shedge and undergraduates Sarah Hashash and Sarah Yun, is an AI-powered method to convert 2D engineering sketches into 3D computer-aided design (CAD) models. The team presented a video showing the manual process of converting sketches, followed by screenshots of a minimum viable demo of the prototype that would perform the process automatically.

“We all took the course for similar reasons; all of us were interested in entrepreneurship,” says Shedge, who has a background in engineering and manufacturing and conceived the initial idea for “We came up with our own ideas and shared them with the class, and the three of us aligned on this one for its good market opportunity.”

“We were blown away by the caliber, the energy, the creativity of the ideas, and especially the talent,” Cashin says. “It all comes down to the people, and Caltech’s got A+ talent. This event showcases that there’s a contagious energy around entrepreneurship at Caltech, so this is the beginning of many things to come.”

Caltech’s Office of Technology Transfer and Corporate Partnerships (OTTCP) oversees not only the Bill Gross Prize but also the Timothy D. Ryan Summer Entrepreneurship Program. The program, funded by entrepreneur Tim Ryan (BS ’78), provides financial support and mentorship for students to develop their innovative ideas into novel commercial products or services.

The winners of the 2024 Timothy D. Ryan Summer Entrepreneurship Program are Audiomatic, an AI-powered video translation and dubbing start-up by undergraduates Nika Chuzhoy and Brian Hu, and ONCOVATE, an AI-tool to support hospitals with cancer care, which was also a finalist for the Bill Gross Prize.
