The San Francisco tech scene is gearing up for summer. A range of companies from artificial intelligence to foodtech raised venture capital funding last month to grow their teams, scale their product offerings and more. Read on to find out what these innovators have in the works.

Largest SF Tech Funding Rounds, May 2023

  1. Anthropic
  2. Zip
  3. Auradine
  4. Amino Health
  5. Air Protein

 

#5. $75 million, May 19

The San Leandro-based startup developed an alternative protein-rich flour using water, renewable energy and elements from the air. The flour can be made into consumer-grade products like steak. With a fresh $75 million in venture capital, Air Protein partnered with ADM, a large crop trader and producer, to build its first commercial production facility. Air Protein is now hiring several engineers and plant operators.

 

#4. $80 million, May 11

Amino Health’s platform helps patients find healthcare providers and benefits programs that fit their needs. Rather than serving consumers directly, the company offers a subscription model for employers who can add Amino to its list of employee benefits. Amino Health secured $80 million in equity and debt financing in May to continue innovating its platform and partner with more businesses.

 

#3. $81 million, May 16

Founded in 2022, Auradine develops web infrastructure solutions, including security, AI and blockchain products. The company raised $81 million in a Series A round that was co-led by Celesta Capital and Mayfield. With plans to speed up its go-to-market efforts, Auradine is currently hiring for a handful of roles.

 

#2. $100 million, May 15

Fintech company Zip is now valued at $1.5 billion following its $100 million Series C raise. Customers like Coinbase, Canva and Databricks use Zip’s platform to manage purchase orders, business-to-business payment and accounts payable. Zip said its internal team has grown from 60 to 250 employees over the last year, and it plans to continue scaling its engineering, product and sales teams.

 

#1. $450 million, May 23

Anthropic aims to create useful, honest and harmless AI tools, including its conversational AI assistant named Claude. Led by Spark Capital, this $450 million Series C round is the company’s second raise in just two months.
