Executive Summary

Many knowledge workers—especially those in client-facing, sales, and product roles—spend hours each week drafting replies, triaging long threads, and hunting for context, creating a persistent drag on productivity across teams of roughly 300M people. The pain is concentrated where email remains the workflow hub: slow drafting, missed action items, and bloated inboxes that cost measurable time. You could build an AI-assisted email overlay/add-in for Gmail and Outlook that provides one-click thread summaries, context-aware draft generation, smart inbox organization, and admin-level privacy controls, with options for regional or on-prem model hosting. The product would be workflow-first (not a replacement client), offering templates, audit logs, and measurable time-savings reports for admins. This market is attractive now: a $9.0B TAM (300M knowledge workers × $30 ACV) and strong tailwinds from LLM adoption and preference for client-agnostic integrations — Market Score 90/100 and Revenue Potential 82/100 reflect real demand. Lower switching friction via add-ins and growing enterprise demand for privacy-conscious deployments make monetization plausible at $20–50 ACV with expansion into teams and compliance tiers. You can differentiate by combining enterprise-grade privacy and compliance (on-prem/regional options, DLP hooks) with tight, non-disruptive integrations and a focus on accuracy/anti-hallucination workflows and measurable ROI for managers. The key risks are medium competition and the execution burden of reliable integrations, model governance, and demonstrable time-saving claims—but if you nail those, the business has clear legs.
