Company profile
researched Aug 2026Hellodeck (product name Deck) offers an AI assistant that operates over the web and over email. Users give the assistant a name and it receives its own address on the agent.hellodeck.ai domain, so it can be CC'd or forwarded messages like a colleague. Once copied on a thread, the assistant follows the conversation, flags items that need attention, and surfaces private notes visible only to the user — it does not reply to other participants on the thread. Users can set a proactivity level (for example, medium for daily summaries, stale-conversation nudges and calendar prep, or high for more active monitoring and draft suggestions).
Beyond thread monitoring, the product supports one-off delegated tasks and recurring routines that run on a schedule and email the result back: morning briefs of the day's meetings cross-referenced with meeting notes, weekly summaries of newsletters in a project folder, account status updates pulled from call transcripts and project boards, and end-of-week recaps of shipped work and upcoming calendar load. The assistant is described as retaining context on files, decisions and details, and as learning the user's writing style, priorities and important contacts from stated instructions. Integrations referenced include Calendar, Slack, Notion, Granola and Fireflies. The company positions inbox access as optional, stating the assistant reads a user's inbox only if the user connects it.
Deck also markets a version aimed at investment teams, with an encryption mode built on Trusted Execution Environments (TEEs). In that mode, according to the company, confidential material such as due diligence research, financial projections and deal pipeline details is processed inside cryptographically isolated hardware environments, so data is not exposed in plain text to model providers or accessible to Deck during computation. Marketed use cases include investment memo and IC memo generation, data room summarization and underwriting memo automation. A community post from the company also described Deck as a platform for managing deal flow, diligence and project work in one place.

Market position
Positions itself as an AI assistant that works entirely through email and the web rather than as another application to open, and, for investment teams, as an AI tool whose confidentiality architecture addresses the data-exposure objections it says have stalled AI adoption in deal workflows.
Distinguishing features cited by the company: the assistant has its own user-named email address and is reached by CC or forward; it replies only to the user and never to others on a thread; inbox connection is optional; proactivity is user-configurable; scheduled routines deliver research by email; and an encryption mode based on Trusted Execution Environments keeps data inside hardware-protected environments during AI processing.
Technology
An email-native agent that receives its own address (name@agent.hellodeck.ai), ingests CC'd or forwarded threads, monitors conversations at user-configurable proactivity levels, maintains persistent memory of preferences, contacts, files and decisions, and executes scheduled routines that run research and return results by email. Integrations include Calendar, Slack, Notion, Granola and Fireflies. For sensitive workloads, Deck offers an encryption mode using Trusted Execution Environments, in which computation occurs inside hardware-isolated environments so data is not decrypted into a model provider's infrastructure.
Go-to-market
