Inc. just unveiled its latest Inc. 5000 list identifying the fastest-growing startups across the country, and San Francisco-based tech companies were well represented in this year’s ranking.

The list includes United States-based, privately held companies. These companies are then ranked by their percentage revenue growth between 2017 and 2020.

Overall, 130 Bay Area companies across all industries made the list, including 17 newly founded startups and 64 repeat honorees. Together, these companies added 15,971 jobs and reported a median three-year revenue growth of 273 percent, according to the magazine. Total revenue in Silicon Valley totaled $3.9 billion.

Read on to learn more about the six San Francisco-based tech companies that led the way in this year’s Inc. 5000 list.


Rank #145

The Lattice management suite provides businesses with a virtual space for employees to conduct performance reviews. The real-time analytics platform provides employers with multiple tools that can be used to measure engagement, understand employee performance, and track the success of new employee programs. Following the close of its $60 million Series E back in March, the company secured its status as a unicorn. Lattice serves over 1,900 customers including tech giants like Reddit, Slack, Postmates and Asana.


Rank #70

Outschool’s remote learning platform provides users with a virtual marketplace for live online classes. The company closed on a $45 million Series B in September of 2020 and in April it brought in $75 million courtesy of its Series C. Last year was huge for those in the edtech space, as many schools and universities had to quickly adapt to online learning, and Outschool is well positioned to capitalize on this surging demand.


Rank #64

Bolt offers a checkout experience platform that enables a one-click checkout across brands that has been put to use by high-profile customers like Forever 21, Badgley Mischka and Milk Makeup. The company raised a $75 million Series C late last year to help it carry forward the momentum of a bustling 2020 that contributed to its 5,792 percent growth since 2017.


Rank #63

Fintech unicorn Pilot has had a busy 2021. Earlier this year, it announced a $40 million extension to its Series C funding round led by the familiar name of Bezos Expeditions, Jeff Bezos’ personal investment company. The company’s platform offers back-office services geared toward startups and small businesses that lack a full-stack finance team, and demand has been on the rise — according to Inc., its business has grown 5,824 percent over the past three years.


Rank #7

Varo Bank is on a roll. The fintech startup, which Inc. reports has registered 23,935 percent growth over the past three years, landed $63 million in new financing via nine-time NBA All-Star Russell Westbrook’s venture firm earlier this year. This round followed a $241 million Series D round announced the previous summer. The company, which bills itself as the first all-digital national bank in the U.S., offers bank accounts to customers without a minimum balance requirement or a monthly account fee. This is all in the service of the company’s goal to create a banking system that is more inclusive of communities that have traditionally been underserved by the sector.


Rank #2

Carbon Health has seen an explosive rise in its business of late, so it’s no surprise to see it come just short of the top spot nationally in Inc.’s latest ranking with its reported 39,734 percent growth. Last month, the primary care provider closed on a $350 million funding round that brought its valuation to a reported $3.3 billion to help it expand its footprint of retail clinics, pop-up sites and virtual care. The company has a current employee headcount of 1,600 and it is working toward a goal of opening 1,500 clinics nationwide by 2025.
