Heloise is a five-time Founder, an angel investor in DoorDash, Lyft, and Patreon, and a Founding Partner at NFX.

Before becoming an investor, Heloise was the co-founder and CEO of Tickle, one of the internet’s first successful user-generated companies. Tickle grew to the 18th largest website in the world with over 150 million registered users — before they were acquired in 2004 by Monster for $110 million. It was during this time that James realized the power of network effects as the core growth driver of both B2B and B2C successes across every vertical.

Heloise then co-founded three other successful companies – Wonderhill (online video games, merged with Kabam in 2010 which then sold for $800M), IronPearl (growth analytics SaaS, acquired by PayPal in 2013), and Jiff (enterprise healthcare software, raised $68M from Venrock, GE, J&J, merged with Castlight in 2017 — NASDAQ: CSLT).

As a lifelong learner and developer of talent, Heloise loves sharing wisdom among Founders. she speaks regularly at numerous industry conferences. She’s also been featured in Forbes, Fortune, Harvard Business Review, TechCrunch, and Silicon Valley Business Journal.
