Odo

What Odo does

Odo is a Denver-based, Y Combinator-backed software company founded in 2023 that builds an AI-powered email assistant designed for founders, startup executives, and sales professionals. The product is a self-serve SaaS application accessible via app.useodo.com that connects to a user's inbox and delivers four integrated capabilities: a Daily Briefing that surfaces priority items in a 2-minute morning brief, natural-language inbox querying (e.g., "which prospects should I follow up with this week"), voice-tailored reply drafting that learns individual writing style and tone, and an organized inbox view where important emails rise to the top. The underlying technology stack combines natural language processing for inbox comprehension, generative AI for personalized draft production, recommendation logic for prioritization, and autonomous-agent patterns for continuous inbox monitoring. Integrations with Google Calendar and Linear extend the briefing surface into calendar and engineering issue-tracking context.

The company operates a horizontal product-led growth motion targeting individual users — primarily busy founders and sales professionals — who can sign up and onboard independently, with the expectation of organic organizational expansion over time. Pricing is not publicly disclosed; the revenue model is recurring SaaS subscription. The company has raised $500,000 in seed funding from Y Combinator (September 2024), holds CASA Tier-2 and SOC 2 Type 2 security certifications, and stores data on US-based infrastructure. Headcount is 1–10 employees, led by CEO/co-founder Yooni Ahn and CTO/co-founder Andrew Wagner. Note: the firmographic short description references government contracts, but all detailed product, technology, and website evidence consistently describes an email assistant product — this analysis is grounded in the detailed evidence.

Core offering

Odo is an AI-powered email assistant that monitors users' inboxes, delivers prioritized daily morning and evening briefings, and drafts replies in the user's own writing style. The product also supports natural language queries to retrieve information and follow-up prospects from email history, integrating with Google Calendar and Linear to surface notifications alongside email.

Product overview

Odo is a single unified AI email assistant product. The core offering combines four main capabilities: (1) Daily Briefing that reads through the inbox and flags important items each morning and evening, (2) an Ask feature that allows natural language queries to search and retrieve information from emails, (3) Draft capability that learns the user's writing style and generates personalized reply drafts, and (4) an organized inbox view where important emails automatically rise to the top. These features work together as an integrated email intelligence system rather than separate modules.
