Invest early and stand by your bets. Don’t buy logos or chase unicorns. That’s the Accel philosophy. At 35 years old, it has served them well, bagging the firm dozens of high-profile exits, including nine IPOs and 12 acquisitions in the last four years.

Now, sources confirm to TechCrunch, the respected venture capital firm has nabbed $2.525 billion — its largest pool of capital yet — for three new funds: $525 million for its fourteenth early-stage fund, $1.5 billion for its fifth growth fund and $500 million for its second Leaders Fund, or a dedicated pool of capital meant to help the firm strengthen its positions on particularly competitive bets.

Accel, which operates offices in Palo Alto, San Francisco, London and Bengaluru, is hot off the heels of a big exit. Its portfolio company HotelTonight, in which it was the very first institutional investor, is selling to Airbnb in what is the home-sharing company’s largest acquisition yet. The deal is said to be worth roughly $465 million, or just above the $463 million valuation the on-demand hotel booking application garnered with a $37 million Series E in 2017.

The firm can thank partner Ping Li and former partner, Theresia Gouw, now a co-founder at Aspect Ventures, for introducing Accel to HotelTonight back in 2011. Accel and Battery Ventures co-led HotelTonight’s Series A and the firm subsequently invested in HotelTonight’s Series B, C, D and E financings, holding true to its promise to stand by its bets.

Today, Accel is the largest stakeholder in HotelTonight and can expect a decent payout in the coming months. Workplace messaging platform Slack, however, is Accel’s true portfolio standout. The company, worth more than $7 billion, is expected to go public this year. In February, the San Francisco-based unicorn filed confidentially with the U.S. Securities and Exchange Commission to make its public market debut; whether that be via a traditional initial public offering or a direct listing, a newfangled approach to going public, is still up in the air.

Accel, at consumer technology investor Andrew Braccia’s recommendation, invested in Slack when it was still Tiny Speck, a seed-stage gaming startup that would go on to become an office necessity. When Tiny Speck pivoted to become Slack, the company’s chief executive officer Stewart Butterfield offered to pay back it’s Series A and B investors, including Accel. Braccia declined.

“The reason we invested in Tiny Speck was because we were investing in that team,” Braccia told TechCrunch in 2015. “I told Stewart, ‘if you want to continue to be an entrepreneur and build something, then I’m with you.’ ”

Now owning a roughly 20 percent stake in Slack, Braccia’s faith in Butterfield will result in a billion-dollar payday for the firm.

Some other high-profile wins for Accel include Qualtrics, which famously accepted an $8 billion acquisition offer hours before completing a Nasdaq IPO. According to Qualtrics’ IPO paperwork, Accel owned a stake worth more than $1 billion. PagerDuty, which is said to have confidentially filed in January, and CrowdStrike, a cybersecurity business that reportedly hired banks for its IPO last fall, are among Accels’ upcoming exits.

Since Accel’s 2016 fundraise got them a fresh $2 billion to invest in startups, the decades-old firm has nabbed some younger talent to help it navigate an inevitable generational transition. Shortly after that fund announcement, Accel added principal Amit Kumar and partner Steve Loughlin, a pair of co-founders of Accel portfolio companies CardSpring and RelateIQ, respectively. In 2018, the firm hired Maya Noeth as a principal to lead its consumer growth investments, Ethan Choi to back startups in the enterprise and consumer-subscription spaces and Cherry Miao as a vice president focused on growth-stage companies.

Its newest cohort of dealmakers — poised to become partners down the line — indicates Accel is conscious of an impending generational transition and prepared for the older investors to pass the baton to the younger folk.

Accel is among several incumbent venture funds to raise money from limited partners in the last year. Bessemer Venture Partners, one of the oldest players in the game, closed on $1.85 billion for its tenth flagship fund in October; Insight Venture Partners brought in $6.3 billion in July; Kleiner Perkins raised $600 million for its eighteenth early-stage fund in late January; and Menlo Ventures grabbed $500 million for Series B and C rounds in February. Other outfits, NEA for example, are in the process of closing up big, big funds.

At a time when nouveau venture funds are raising funds equipped with innovative investment strategies and young teams, Accel and some of its counterparts are proving old dogs can learn new tricks — or, at least, continue to lead the pack with no new tricks at all.
