Alex Taussig

The single activity I've practiced more than any other is asking the best possible question and listening hard to the answer.

Alex joined Lightspeed in 2016 and co-leads the fund’s Consumer investment team. He has spent the last 14 years as a technology investor and has partnered with dozens of founders across a variety of industries, including food, CPG, apparel, wholesale, education, supply chain/logistics, and financial services. Alex also co-leads Lightspeed’s emerging LATAM practice.

Alex currently supports companies across the US, Europe, and LATAM, including All Day Kitchens, Archive Resale, AWA Studios, Daily Harvest, Faire, Found, Fourth Wall, Frubana, Kikoff, Outschool, Trendsi, Vinted, and Zola. At a prior venture capital firm, he also supported over a dozen companies including thredUP (IPO TDUP, 2021), Carbon Black (IPO CBLK, 2018), 2U (IPO 2014, TWOU), and RentJuice (acquired by Zillow, 2012).

Alex is a trained research scientist and breaks down business problems with deductive logic and analytical rigor. He originally studied physics at Harvard College, where he graduated summa cum laude, and then went on to receive a Master’s degree in materials engineering from MIT, where he was part of a research group building the first fully optical computer chip. Alex also received an MBA from Harvard Business School, where he was a Baker Scholar, an honor given to the top 5% of the graduating class.

Alex’s newsletter “Drinking from the Firehose” ( is currently on hiatus, but still has some great content! He lives in San Francisco with family and enjoys anime, muay thai, and heavy metal music.
