Writer, the three-year-old San Francisco startup that has, since its inception, focused on building out a secure generative AI platform for enterprises to help them across functions, announced it has raised $100 million in Series B funding today, in a round led by ICONIQ Growth with participation from WndrCo, Balderton Capital, Insight Partners, and Aspect Ventures.

Notably, Writer’s enterprise clients including processional services company Accenture and investment giant Vanguard also joined in the round, signaling strong confidence in Writer’s offerings.

The money will help Writer continue to build out more new features and AI agents for its “full stack” of enterprise-friendly software applications and connections around its three proprietary AI models: Palmyra Small (128M), Palmyra Base (5B), and Palmyra Large (20B), which can already help enterprises do everything from create content and emails to transcribe audio and summarize it.

While the B2B software market has for the last six months been absolutely inundated with new generative AI tools and applications — many of them making use of large language models (LLMs) such as OpenAI’s ChatGPT or Meta Platforms’ Llama 2, Writer aims to stand out with its in-house trio of Palmyra models.

The company said its press release today that it is targeting people working in “support, operations, product, sales, HR, marketing, and more,” functions.

Some of the models are tailored for specific industries like healthcare and are fully auditable—a unique selling point in a field often criticized for its “black box” nature.
