Fareed Mosavat is a Visiting Partner at a16z Speedrun, a 12-week founder accelerator at the intersection of technology and entertainment. He came to venture capital after a career arc that started in physics simulation at Pixar and wound through product and growth leadership at Zynga, RunKeeper, Instacart, and Slack, before he ran product education for thousands of PMs as Chief Development Officer at Reforge. Today he backs AI-native B2B startups, co-hosts the Unsolicited Feedback podcast with Brian Balfour, and writes about what it actually takes to build products people love.
Mike Duboe is a General Partner at Greylock Partners, one of Silicon Valley's oldest and most storied venture firms. A former operator who scaled Stitch Fix's growth org from zero to 20 people and helped take the company through IPO, Duboe brings rare depth to the investor seat - having managed nine-figure marketing budgets and built scrappy product-led growth teams. He focuses on commerce, marketplaces, and vertical software, with an investment philosophy rooted in learning velocity and disciplined, sustainable growth over vanity metrics.
Brian Balfour is the founder and former CEO of Reforge, the professional development platform for experienced product, growth, and marketing practitioners that grew to 100,000+ alumni before being acquired by Miro in March 2026. Now Chief Growth Officer at Miro, he is best known for the Four Fits Framework - the thesis that Product-Market Fit alone cannot drive $100M+ growth, and that market, product, channel, and model must all interlock. A former VP of Growth at HubSpot, serial entrepreneur, and Venture Partner at Long Journey Ventures, Balfour is one of the most influential thinkers in the product-led growth movement.
Casey Winters is a co-founder and CEO of SuperMe, an AI-native professional network backed by Greylock and Reid Hoffman. He is one of the most respected growth and product operators in Silicon Valley, having scaled Grubhub from 40,000 customers in 3 cities to 3 million users in 1,000+ cities, then led Pinterest's growth from 40 million to 400 million users, and later served as CPO of Eventbrite through a pandemic that wiped out the live events industry. A longtime Reforge program partner and prolific writer at caseyaccidental.com, Winters is known for first-principles thinking, blunt contrarianism, and a deep aversion to cargo-cult growth frameworks.
Elena Verna is one of Silicon Valley's most respected growth operators - a former SVP of Growth at SurveyMonkey, interim CMO at Miro, and current Head of Growth at Lovable (the AI app-builder that hit $200M ARR in under a year). Known for popularizing Product-Led Growth frameworks, she runs 'Elena's Growth Scoop' newsletter with 89,000+ subscribers and a 40% open rate, and is a Partner at Reforge. She immigrated from Russia at 14 with $100 and no English, and has built a career on the principle: 'I will figure it out.'
