Background
Howard Lindzon is a Canadian-born entrepreneur, angel investor, and author based in Scottsdale, Arizona 12. He graduated from Forest Hill Collegiate Institute in Toronto in 1986, received a Bachelor of Commerce from the University of Western Ontario, and earned an MBA from Arizona State University (with additional studies at Thunderbird School of Global Management) 12.
Lindzon’s career began inauspiciously: he was laid off from his first brokerage firm job during the October 1987 crash just months after starting 12. He went back to school, then began managing a hedge fund in June 1998 1.
In 2006, Lindzon created Wallstrip, a daily financial satire video podcast that The New York Times described as “Squawk Box Meets Saturday Night Live” 12. Wallstrip aired over 300 episodes before being acquired by CBS in May 2007 12.
In 2008-2009, Lindzon co-founded StockTwits with Soren Macbeth, a social network for investors and traders that pioneered the “cashtag” (e.g., $AAPL) 12. StockTwits grew to over 6 million monthly unique visitors and raised $30 million in 2021 23. In 2024, Lindzon returned as CEO of StockTwits 23. Time magazine named StockTwits one of its “50 Best Websites” in 2010 1.
In 2009, Lindzon co-founded Social Leverage, a seed-stage venture capital firm, alongside Tom Peterson 23. Social Leverage has deployed five funds, invested in 150+ startups, and most recently raised an $85 million Fund V 34. The firm has seen 4 IPOs and 48 acquisitions across its portfolio 3.
Lindzon’s earlier investments include Rent.com (acquired by eBay in 2005 for $415 million), Golfnow.com (acquired by Comcast in 2008), and LifeLock 1.
Stated Thesis
Social Leverage describes itself as investing in “exceptional founders building the future of finance and vertical AI” 34. Lindzon has stated the firm does “seed checks into financial companies and enterprise software up to $1M” 5.
Lindzon has articulated his investment philosophy around several themes:
On founder selection: “A good founder overcomes a small market problem and has domain experience. Someone that understands the timing and commitment needed” 5.
On the investor role: “A great investor should help in recruiting and fundraising for founders. We want to make sure we help them raise capital and recruit great people” 5.
On identifying opportunities: He targets “financial services for investors, traders and the mass affluent” with emphasis on “non-obvious products, companies and founders” 6.
Lindzon prefers being called “an investor in great businesses” rather than a “venture capitalist” 7. He has emphasized relationship-building: “Spotting talent and building relationships is becoming more important” 5.
