Sierra AI introduces Ghostwriter platform for automated agent development.

Sierra AI introduces Ghostwriter platform for automated agent development. March 27, 2026 at 6:25 PM - by MLQ Agent Key points. * Sierra AI introduced Ghostwriter, a tool that builds production-ready AI agents using natural language commands and uploaded materials like SOPs and transcripts. * The platform supports voice, chat, email and over 30 languages, automating development without manual editing or technical expertise.1 * Ghostwriter reduces Sierra's reliance on on-site engineers, aiming to lower operational costs amid enterprise AI adoption.2 * Sierra, valued at $10 billion, was co-founded by Bret Taylor and Clay Bavor.25 AI startup Sierra has launched Ghostwriter, a self-service platform that enables organizations to create AI agents for customer service and other functions using plain English instructions. The tool analyzes documentation, support transcripts and process materials to produce agents deployable across voice, chat, email and more than 30 languages.12 Platform capabilities. Ghostwriter automates the full agent development process, eliminating the need to edit journeys, write integrations or triage issues manually. Users upload standard operating procedures, transcripts from support calls, whiteboard sketches, process documentation or audio recordings, or simply describe goals in natural language. The agent then identifies behaviors, edge cases and builds sophisticated agents with built-in guardrails. 1 It operates on rearchitected headless infrastructure, accessing the full Sierra workspace for testing in a sandboxed environment. 1 Business model shift. Previously, Sierra deployed agents with on-site engineers, but Ghostwriter introduces a self-service model to cut operational costs. This comes as large enterprises accelerate AI implementations in customer service, sales and supply chain after 2025 testing phases. 2 The platform creates an 'agent assembly line' that continuously analyzes interactions, improves agents and prepares updates for review. 1 Company background. Founded in 2023 by former Salesforce co-CEO Bret Taylor and ex-Google executive Clay Bavor, Sierra focuses on AI agents for customer experience across digital and voice channels. The company raised $635 million total, reached a $10 billion valuation and reported around $100 million in annual recurring revenue in 2025. 5 Sierra integrates large language models from OpenAI, Anthropic and Meta. 5 Self-Service deployment shift. Ghostwriter addresses a core challenge in AI agent deployment by shifting from engineer-dependent services to autonomous, natural language-driven development. This reduces deployment barriers for enterprises lacking in-house AI expertise, potentially accelerating adoption in high-volume areas like customer service where Sierra already serves Fortune 100 companies. 3 The rearchitecture to headless infrastructure enables reliable autonomous improvements, positioning Sierra to scale beyond its current operational model constrained by human engineers. 12 The launch reflects broader industry trends toward outcome-based AI, moving away from traditional SaaS seat-based pricing. By enabling an 'agent assembly line,' Sierra can deliver continuous optimization without proportional cost increases, a key differentiator in a market crowded with conversational AI vendors. 13 This self-sufficiency could solidify Sierra's competitive edge, leveraging founders' networks for enterprise traction while minimizing service delivery overhead. 5 Enterprise scaling trajectory. Enterprise uptake of Ghostwriter will likely grow as companies integrate AI agents into sales, supply chain and customer operations following 2025 pilots. Sierra's focus on multi-channel, multi-language support aligns with global demand, potentially boosting its $100 million ARR trajectory. 25 Ongoing improvements via the assembly line could enhance agent reliability, drawing more Fortune 100 clients discussed in recent panels. 3 Competitive pressures from platforms like Teneo and Voiceflow may intensify, but Sierra's multi-LLM approach and founder pedigree provide defensibility. Future developments could include expanded integrations and voice features, capitalizing on behavioral shifts in enterprise AI spending observed by investors. 35 Regulatory scrutiny on AI reliability in customer-facing roles remains a watchpoint, though built-in guardrails mitigate risks.

No worries vs please hold: Sierra comes to Australia.

No worries vs please hold: Sierra comes to Australia. Bret and I are excited to share that Sierra is opening an office in Sydney, Australia following its expansion to Singapore, Tokyo, Madrid, Paris, and London. Despite all the advances in technology over the last forty years, customer experiences today are all too often defined by generic websites and apps, and if you can find a phone number, an IVR followed by a long wait on hold. Sierra helps businesses solve the age-old tension between the cost and quality of customer experiences - enabling the great companies of the world to show up at their best, day in, day out. AI agents built on its platform are available 24/7 in over 30 languages, and with no wait time. They can do everything from product discovery to sign-up and sign-in, troubleshooting and churn management - increasing customer satisfaction and revenue for companies around the world. For example, Rocket Mortgage, one of the largest mortgage originators in the US, is doing $1BN in loan volume a month, with home buyers using their agent four times as likely to complete the process. If you're interested in building better, more human customer experiences with AI, please reach out here. And Sierra is hiring! If you're interested in being part of one of the fastest-growing enterprise software companies in history, please apply to join Sierra.
