How edtech startup Sphere raised over $4 million and got new customers after landing a spot in Y Combinator's coveted accelerato...

Aug 16, 2022

Redeem now Sphere is a career upskilling startup that trains employees in machine learning and data science. The company was part of Y Combinator's winter 2022 batch and got customers like Stripe and Tinder. Now, the team has raised $4.3 million in seed funding led by Felicis Ventures. San Francisco-based Sphere is a continuing professional education platform aiming to skill-up mid-career tech employees. The startup just raised $4.3 million in seed funding for its upskilling classes in software engineering skills like machine learning and data science, and has plans to add more courses to its curriculum in the coming year. The round was led by Felicis Ventures, with participation from Y Combinator , Uncommon Capital, and several prominent angel investors including some of the founders of Go1, Lyft, BetterUp and Flexport. Founded in 2020 by Nicholas Rudder and Adrian Sarstedt, Sphere was originally called ScholarSite and was intended to be a platform for live-taught online corporate education. Rudder, who is Australian, had been doing a Master's program in Europe that had to become virtual during the pandemic, and found the whole experience to be very out of touch with what skills were actually needed for today's workforce, he said. "I was basically paying for what was effectively a very poorly run Zoom course while taking on a ton of debt," said Rudder. "So I started working on Sphere right then because I felt we could build something far better, and a much more enticing learning experience for professionals. "  Sphere hosts instructors who are working professionals in machine learning and data science at some of the largest tech companies like Netflix, NVIDIA, and Slack to conduct live-streamed, interactive three-week courses. The instructors are well-known experts and influencers in the world of computer science, like Xavier Amatriain, who built Netflix's machine learning algorithm, Chip Huyen, who worked at Snorkel AI and teaches machine learning at Stanford, and Ronny Kohavi, who designed the AB testing systems at Airbnb, Microsoft and Amazon. The teachers have a large degree of independence and build out their own curriculum for the most part, said Rudder. By hosting the classes live rather than asynchronously, Sphere has seen completion rates of over 80%, compared to 4% on average for asynchronous classes, he said. A typical course costs around $1,000 per student, said Rudder. Some students take the courses independently, but  Sphere has been approved as a provider for 700 different tech companies to have their course fees covered for employees as a learning and development expense. The startup got a big boost in these contracts after getting accepted into Y Combinator's winter 2022 cohort this year, which was the first to take place after the accelerator announced its new standard deal . Sphere used the connections it made during the program to meet with several VCs including the team at Felicis Ventures, who signed on to Sphere's seed round as the cohort wrapped up in the spring. Some of these enterprise clients include Flipkart, Tinder, Flexport, and Stripe. "Sphere is tapping into a large, growing market but one that also has low satisfaction," said Ryan Isono, a vice president at Felicis Ventures. "They've been able to bring on an incredible, global customer base in a short amount of time. "  The Sphere team hopes to use the new funding to make new hires on the growth and engineering teams as well as source more bulk contracts with enterprise clients. Subscribe to push notifications
