It’s a pretty good week for Altos Ventures

Covering the recent spate of public debuts this week, one name jumps out: Altos Ventures. 

Founded in 1996 with a focus on early-stage investments, Altos Ventures invests across both South Korea and the U.S., and has picked up stakes in businesses including Chowbus, Quizlet, and Toss Bank.

Along the way, the investment firm also picked up a substantial stake in gaming company, Roblox, which, as you may have read, went public via direct listing on Wednesday, soaring on its debut. The valuation of the company rose as high as $45 billion on a fully-diluted basis, making CEO Dave Baszucki a billionaire four times over. 

It also turned Altos Ventures’ stake in Roblox worth $7.5 billion. Having first invested in a $2.9 million Series C round in the company back in 2008, Altos Ventures gradually added to its stake over time, investing roughly $141 million in the far meatier Series F, G and H rounds, according to Roblox’s prospectus. Which,even by a very rough, back-of-the-envelope calculation = mega, mega returns. 

Oh, and it also so happens that Altos Ventures is an investor in another company going public today: South Korean e-commerce business Coupang. According to Pitchbook, Altos Ventures made its first bet on the delivery company in 2011. On Thursday, the company raised $4.6 billion ahead of its debut on the New York Stock Exchange, valuing it at about $63 billion on a fully-diluted basis. Granted, that stake is much smaller than its Roblox bet (with Altos Ventures holding some 23.6% of Roblox’s Class A shares prior to the listing): Altos Ventures is not named as an investor in Coupang’s IPO filing, meaning it holds less than 5% of the e-commerce business.

Not a bad week for Altos Ventures.

IS BITCOIN BAD FOR THE CLIMATE? On Monday, I wrote about one of the costs of the rising interest in cryptocurrencies, the climate. In it, I alluded to researchers who say the mining of the digital coins takes an outsized amount of electricity, which in turn, mainly comes from less environmentally-friendly sources, such as coal. Union Square Ventures Partner, Fred Wilson, wrote back, saying he believed I oversimplified the issue and that effectively, more data is needed on the topic.

“It is time for the crypto industry to study this issue carefully and provide real data. I would like to see carbon emissions from proof of work mining measured over time and projected into the future,” he writes.

Here’s his blog post in full on the topic.
