By Amit Chowdhry ● Mar 28, 2023
  • Character.AI announced recently that it closed a $150 million funding round. These are the details.

Character.AI announced it has closed a $150 million Series A fundraising round at a $1 billion valuation led by Andreessen Horowitz (a16z) with participation from previous investors, including Nat Friedman (former GitHub CEO), Elad Gil, SV Angel, and A Capital. Andreessen Horowitz General Partner Sarah Wang will join Character.AI’s board of directors.

The funding will enable Character.AI to continue its significant growth trajectory by expanding its computing abilities, which would drive a more sophisticated model with advanced reasoning and greater accuracy, delivering new features and capabilities to users, and expanding its engineering team.

Founded in 2021 by artificial intelligence (AI) and large language model experts Noam Shazeer and Daniel De Freitas, Character.AI is considered at the forefront of critical conversational AI technology that makes everyday tasks easier when solving complex societal issues.

Character.AI essentially offers users the ability to create a fully-customizable and personalized AI companion with a distinct personality. Whether users are seeking a sympathetic ear or an analytical problem-solver, there’s an AI at Character.AI to meet the unique needs of every person. And for those less interested in complete personalization, the growing community of creators at Character.AI have developed millions of AI characters for people to connect and use.

Since the platform launch in beta in September 2022, Character.AI experienced rapid growth, including:

— Nearing 100 million monthly site visits, which was a four-fold increase in two months.

— An average time on site of over two hours per day for users who send a message.

— Over two billion messages sent by users since launch. And the first one billion user messages were sent in the span of four months. The second billion user messages were sent in the past one month.

— Users have created over 2.7 million characters. The platform launched with fewer than 100.

— Character.AI is now placed in the top 400 websites globally based on monthly visits according to Similarweb rankings.

Character.AI also announced it released an early preview of C1.2, which is their new, smarter, more helpful model – which introduced new productivity capabilities and builds on the entertainment, roleplay and emotional support of the C1.1 model. The C1.2-powered Characters can help draft emails, assist with test prep by being a study buddy, brainstorm ideas, etc.
