Vellum

What Vellum does

Vellum (legally Vocify, Inc.) is a New York-based, venture-backed Personal AI assistant company that builds an always-on AI agent with persistent memory, autonomous task execution, and multi-channel deployment across macOS, iOS, web, Slack, Telegram, voice, and CLI. Its core product wraps third-party foundation models (Anthropic Claude, OpenAI, Gemini, xAI, and inference providers such as Cerebras, Fireworks, Baseten, Together) with a proprietary memory layer using hybrid search, a Skills framework (email triage, calendar, meeting prep, delegation, research, communications, project tracking, travel), a Computer Use skill for autonomous screen control, and an Agent Node for building AI agents with automatic schema generation. The MIT-licensed open-source core (vellum-ai/vellum-assistant) underpins a community-led developer motion, while SOC 2 Type II compliance and no-training-on-user-data positioning target enterprise buyers.

The company operates a hybrid go-to-market. It runs a product-led growth funnel with a free local tier using the user's own API key and a $1/credit usage-based Vellum Credits system (capped at 1,000 credits, 12-month expiry), complemented by a managed cloud subscription. Following its $20M Series A in July 2025, Vellum expanded into enterprise field sales with VPC, on-premises, SSO, RBAC, and audit-visibility options targeting organizations deploying AI agents at scale. Customer segments span individual professionals, AI developers, and enterprise teams, though publicly named customers are micro-segment (a vice mayor's personal use, a solo Shopify store owner). Total disclosed funding is approximately $25.5M across a $500K YC standard deal (April 2023), $5M seed (July 2023, YC W23 with Eastlink Capital, Rebel Fund, Pioneer Fund), and the $20M Series A (July 2025, Leaders Fund lead).

Broad incumbents

• Anthropic (Claude): Anthropic's Claude is Vellum's primary model provider and a direct competitor via its own consumer Claude products and Claude Cowork. This dual role as supplier and competitor is unique and central to Vellum's strategic positioning.
• OpenAI (ChatGPT): ChatGPT is the broadest incumbent in personal AI, with native memory features, custom GPTs, and a developer platform. It competes with Vellum's core assistant value proposition while also representing the underlying model layer that Vellum alternatives could be built on.
• Notion AI: Notion AI is an embedded AI assistant within the Notion workspace, offering productivity features like summarization, content generation, and Q&A. It competes for the same knowledge-worker productivity budget as Vellum and has broader enterprise distribution.
• Google Gemini: Google Gemini is a personal AI assistant with deep integration across Google Workspace (Gmail, Calendar, Meet) — overlapping directly with Vellum's email triage, calendar, and meeting prep skills. Google's distribution via Android, Workspace, and Pixel devices is a significant competitive moat.
• Apple Intelligence: Apple Intelligence is Apple's on-device personal AI integrated across iOS, macOS, and Siri. It directly competes with Vellum's Mac and iOS deployment strategy and offers OS-level access that third-party apps cannot match.

Direct peers

• Replika: Replika is a personal AI companion with persistent memory and a multi-channel identity. While Replika leans toward emotional support and companionship rather than productivity, it shares with Vellum the architectural pattern of a personal AI with persistent identity and cross-channel deployment.
• Lindy.ai: Lindy.ai is a personal AI assistant platform focused on productivity automation — email, calendar, meetings, and workflow automation. It is the closest direct competitor to Vellum in the personal AI productivity category, with similar target customers (knowledge workers, executives) and overlapping features (skills, integrations, multi-channel).
• Mem: Mem is an AI-powered note-taking and memory platform that builds persistent context across user inputs. It overlaps directly with Vellum's persistent memory layer and personalization story, targeting similar knowledge-worker personas seeking AI-augmented productivity.

Emerging players

• Adept: Adept builds AI agents that operate software on behalf of users — directly comparable to Vellum's Computer Use skill and agent capabilities. While focused more on enterprise workflow agents, the underlying technology (model-driven action execution on user interfaces) is highly overlapping.

Others

• Otter.ai: Otter.ai is an AI meeting transcription and note-taking platform that overlaps with Vellum's meeting prep, Fathom integration, and Google Meet workflows. It is an adjacent productivity-AI player rather than a direct substitute but competes for a share of the same knowledge-worker productivity budget.
