About
Writer was founded in 2020 in San Francisco by May Habib and Waseem AlShikh with a mission to bring the transformative potential of generative AI to the enterprise in a way that is accurate, controllable, and deeply integrated with how large organizations actually work. Unlike AI companies that rely on third-party foundation models, Writer developed its own proprietary large language model family called Palmyra, purpose-built for enterprise use cases with a focus on factual accuracy, compliance, and customizability. This model ownership gives Writer a differentiated ability to fine-tune, audit, and optimize AI behavior in ways that API-dependent competitors cannot match.\n\nWriter's platform delivers agentic AI workflows that automate complex, multi-step business processes across functions including marketing, legal, HR, finance, and operations. Fortune 500 companies deploy Writer to build AI applications that generate on-brand content, analyze documents, synthesize information from internal knowledge bases, and execute multi-step workflows with minimal human intervention. The platform includes an enterprise knowledge graph, a no-code AI application builder, and deep integrations with enterprise systems including Salesforce, Workday, and ServiceNow. Writer's agentic architecture allows AI to operate across interconnected tasks — drafting, reviewing, routing, and publishing — rather than just responding to individual prompts.\n\nWriter has raised $369 million in funding and carries a $1.9 billion valuation, with a team of over 2,400 employees supporting rapid enterprise expansion. The company's focus on proprietary models, enterprise-grade security, and workflow automation distinguishes it from both consumer AI tools and infrastructure-only AI providers. As enterprises move beyond AI pilots into production-scale deployments, Writer is positioned as one of the leading full-stack enterprise AI platforms in the market.
