Writer is a full-stack generative AI platform built for large enterprises that need reliable, on-brand, and compliant AI across their organization. Rather than relying on third-party foundation models, Writer develops its own family of Palmyra large language models and pairs them with retrieval, brand-enforcement, and agent-building tooling so that teams in marketing, support, operations, and product can deploy AI applications on top of company knowledge.
The platform combines self-hosted or managed Palmyra models, a knowledge graph that grounds outputs in enterprise data, no-code agent builders, and governance controls for compliance. This vertically integrated approach is positioned as a differentiator against general-purpose assistants, because customers control the model, the data, and the guardrails end to end.
Writer was founded in 2020 by May Habib and Waseem AlShikh, who had previously built the machine-translation company Qordoba together. Habib serves as CEO and has become a prominent voice on enterprise AI strategy, while AlShikh leads the company's technology and model research.
The company has raised a substantial war chest from top-tier investors. In November 2024 it closed a $200 million Series C at a $1.9 billion valuation, co-led by Premji Invest, Radical Ventures, and existing backer ICONIQ Growth, with strategic participation from Adobe Ventures, Citi Ventures, IBM Ventures, Salesforce Ventures, and Workday Ventures, bringing cumulative funding well above $300 million.
Writer is used by Fortune 500 organizations across regulated and brand-sensitive industries, where its emphasis on accuracy, data security, and brand consistency tends to resonate. Its Palmyra models have been benchmarked competitively against leading proprietary models on enterprise-oriented tasks.
For large companies seeking a controlled, governed AI layer rather than a consumer chatbot, Writer offers a credible alternative; smaller teams or individual users, however, may find the platform heavier and more expensive than off-the-shelf assistants.
