It may seem like Boston startups raised a lot more money from investors than last month, but that’s mainly because of Ginkgo Bioworks’ whopping $275 million Series D, which accounts for over 64 percent of the more than $428 million raised in December.

Beyond Ginkgo, other startups that raised large rounds this month include Indigo ($47 million), SolidEnergy Systems ($34.4 million) and Starry ($31 million).

Here are the 18 Boston startups that raised more than $428 million in December:

• Asimov, an MIT-born startup with a plan to build a “one-stop shop for genetic circuit design,” raised $4.7 million in a seed financing round that closed back in May but was announced on Tuesday, BBJ reported. Andreessen Horowitz led the round and was joined by Pillar, Data Collective and AME Cloud Ventures.

• Authess, an edtech startup, raised a $516,000 funding round, which has a target of $1 million, according to a new Form D.

• Coeo, an app-based network that allows users to book studio fitness classes, raised a $160,000 round of “friend and family fundraising,” the company wrote in a press release.

• Commonwealth Crypto, a stealthy crypto startup led by a Boston University professor Sharon Goldberg, raised a $1.5 million seed round that was co-led by Underscore VC, Highland Capital, Notation Capital and the founders of United Bitcoiners. The startup’s co-founders, Goldberg and Ethan Heilman, were previously part of the team behind a trustless anonymous payment hub for Bitcoin transactions called TumbleBit. Commonwealth Crypto is developing tech that can ensure that crypto traders maintain custody of their tokens while using an exchange.
