Overview
Ensis is an AI-powered knowledge engine that integrates directly into Microsoft Office applications (Word, Excel, PowerPoint, Outlook) and includes a Proposal Suite to accelerate RFPs, proposals, spreadsheets, slides, and emails by drawing from a company's verified knowledge base plus the web. The platform is purpose-built for enterprise knowledge-worker productivity and proposal/RFP workflows with tight Microsoft Office integration. Core capabilities include embedded Office modules (Word, Excel, PowerPoint, Outlook), a Proposal Suite that parses RFPs, requirement shredding, generating proposals from approved past submissions, compliance checks, and review workflows. Ensis uses a RAG architecture and is LLM-agnostic (the site states most client models currently use GPT-4o). Security and compliance claims on the site include SOC 2 Type II and CMMC; data is encrypted at rest. Terms and conditions permit users to retain ownership of uploaded user data while granting Ensis a worldwide, royalty-free license necessary to provide the service; Ensis may use Resultant/Aggregate data for R&D/marketing. The terms include mandatory arbitration with an opt-out window of 30 days, waiver of class actions/jury trials, provisions for fees/auto-renewal/suspension for non-payment, limitations of liability, and application of California law with AAA arbitration. Pricing is per-user and provided via custom quotes only (no public seat-tier prices or trial listed); onboarding is white-glove and part of the buyer journey. Founded by Ben Lewis and Jon Sockell; announced a $4M pre-seed on 2024-03-27.
