Mattermark ranked the five fastest-growing Series C startups from last year in its Startup Traction Report, and they are a snapshot of modern trends.

We are taking our education into our own hands, learning new skills through General Assembly and Udemy. We are pursuing our passions and running our own jewelry businesses through Chloe + Isabel – not working for others. And all that takes a lot of time, so we need Blue Apron’s help with the cooking.

Series C is typically the fourth round of funding that a startup raises, after seed and Series A-B.  The size of a Series C round varies, but the startups below were funded to the tune of $15 million to $70 million. Fast growth is determined by the Mattermark growth score, which takes into account monthly unique website visitors, weekly mobile downloads, social media metrics, number of employees, and equity funding.

Here are those hot Series C startups:

1. General Assembly

General Assembly raised a $35 Series C round in March 2014.

Growth score: 3936

Mattermark says: “General Assembly, a tech training center, offers courses that prepare students for careers in the digital economy. It has grown as demand for hackers increases.”

2. Chloe + Isabel

Chloe + Isabel raised a $15 million Series C round in June 2014.

Growth score: 2308

Mattermark says: “Chloe + Isabel is a fashion jewelry lifestyle brand that sells merchandise exclusively through its style experts. Its team has exceeded 1,100 employees despite a below-average Series C investment ($15M).

3. Blue Apron

Blue Apron raised a $50 million Series C in April 2014 and went on to raise $135 million in June of this year.

Growth score: 1988

Mattermark says: “Blue Apron, which delivers recipes and required ingredients to aspiring home chefs, announced that it sells 1 million meals per month. These stellar sales may have incentivized investors to put down $50M in its Series C round.”

4. AdRoll

AdRoll raised a $70 million Series C round in April 2014.

Growth score: 1943

Mattermark says: “AdRoll, a retargeting platform with over 8,000 active advertisers, boasts 600% year-over-year revenue growth. AdRoll has focused on product innovation, including the Facebook Exchange.”

5. Udemy

Udemy raised a $32 million Series C round in May 2014 and went on to raise $65 million in June of this year.

Growth score: 1833

Mattermark says: “Udemy, an online course marketplace in which students learn real-world skills, has attracted more than 4 million students. Udemy’s web and social media metrics improve steadily each month without paid advertising.”

The fastest-growing Series C startups of 2014, along with a wealth of other data on the fastest-growing startups, regions, and industries, are reported in the 2014 Startup Traction Report (get it for $99).

Everything was measured for the 2014 fiscal year, which covers October 2013-September 2014.
