Klaviyo’s next-gen email marketing platform engorges on $320M at a $9.5B valuation

Comment

Email marketing is decades old, but it’s a category that has surprising life in it. Multiple generations of email marketing companies have come through and sustained success, from Constant Contact to Mailchimp. These brands often become household names — after all, you probably have hundreds of emails with their logos attached to the email footer.

Klaviyo is not as much of a household name right now, but it is absolutely on its way to the paramount of the next-generation of email marketing startups.

The company announced today that it has raised $320 million in new capital in a Series D round, led by Sands Capital, a private and public equity investor that has, among many areas of focus, a thesis in ecommerce. That brings the company’s total fundraising to $675 million, following a $200 million Series C round from just six months ago.

Klaviyo was the subject of one of our most recent EC-1 analyses, where we looked at the company’s history of growth, how it is rebuilding what’s been dubbed “owned marketing” (i.e. marketing channels that a business owns like email rather than channels owned by platforms like Facebook and Instagram), how marketers are using Klaviyo post-COVID, and some startup growth lessons from the business as well.

The Klaviyo EC-1

There is nearly 10,000 words of analysis packed into that whole story, so read that or save it for the weekend if you really want to get into the nitty-gritty of Klaviyo’s story and how it is fitting in to the wider email marketing space. But suffice it to say that the company’s secret sauce is perhaps obvious: it’s a marketing company that’s pretty damn good at marketing. That’s allowed it to pull in gargantuan numbers of new customers as many retailers and brick-and-mortar businesses fled online in the wake of the COVID-19 pandemic.

In its press statement, the company wrote that “Klaviyo’s customer base doubled over the past 12 months and the company now serves over 70,000 paying customers, a more than 110% increase from 2019 — ranging from small businesses to Fortune 500 companies, in more than 120 countries.” It also said that it plans to increase its head count from 800 to 1,300 people this year.

The company is headquartered in Boston, and Klaviyo’s all-but decacorn valuation is a major win for the Boston enterprise ecosystem, which continues to percolate on high.

In addition to Sands, Counterpoint Global, Whale Rock Capital Management, ClearBridge Investments, Lone Pine Capital, Owl Rock Capital, and Glynn Capital also joined the round as new investors. Previous investors Accel and Summit Partners also participated.
