Agents are starting to do real work, but they still lack basic infrastructure humans already have: persistent identity, reliable communication, permissions, memory, and a system of record. AgentMail gives every AI agent its own programmable inbox. Developers use our API to create inboxes, send and receive email, manage threads, parse messages into structured data, route webhooks, attach domains, and build agents that can communicate across the internet. We're backed by Y Combinator and have raised $6M led by General Catalyst, with support from the founders of Ramp, Supabase, and HubSpot, as well as Paul Graham. We're early, moving fast, and building in a category without a playbook. If you want to help define core infrastructure for the agent era, we'd love to meet you. ## TLDR We're hiring a GTM Engineer to build the machine behind AgentMail's growth: the data pipeline, the outbound engine, and the source of truth the whole company runs on. This is a build-and-own role, not a support role. ## WHAT YOU'LL DO - Own the growth data layer end to end: instrument the funnel, enrich every signup, and build the dashboards the company treats as the source of truth - Turn our best customers into ten more: lookalike modeling, automated outbound, LinkedIn plays, and surfacing champions and buyers inside companies already using us - Run experiments across the PLG engine (content, integrations, backlinks, paid) and double down on what moves signups - Connect the stack through APIs, webhooks, and automation so data moves cleanly between PostHog, our CRM, enrichment providers, and outbound tooling - Decide what tools we use and what gets kicked to the curb. You own the stack - Build AI-powered internal tools - Ship systems from prototype through rollout and adoption, then hold your ground. You built it, the team follows it ## WHAT WE'RE LOOKING FOR - A technical foundation: CS, data science, or equivalent. You write real scripts in Python/TypeScript/SQL, wire APIs together, and are dangerous with Claude Code or Codex - You've seen a great growth motion up close, or you've been obsessively reverse-engineering how the best PLG companies grow - High agency in ambiguity: you call out what's broken, come with an opinion, and fix things without being asked - Low ego, high buy-in - Organized enough that the systems you build don't rot. Clean data is a discipline, not a feature - You want to help invent a market, not just run someone else's process ## BONUS POINTS - Hands-on experience with tools like Clay, n8n, enrichment waterfalls, or sending infrastructure - PostHog fluency (we live in it) - You've shipped agentic workflows or internal AI tooling before - You've worked at or studied a technical PLG company up close ## About AgentMail ## Company Overview - **One-liner**: AgentMail provides an API-first email inbox service built specifically for AI agents, enabling them to send, receive, and manage emails autonomously. - **Entity Type**: Private (YC S25, Seed-stage) - **Headquarters**: San Francisco, California, United States - **Founded**: 2025 - **Founders**: Haakam Aujla, Adi Singh, Michael Kim ## Core Business - **Primary industry**: Email infrastructure / AI agent tooling - **Target customers**: B2B – developers and platform builders creating AI agents that need to communicate via email - **Mission or purpose**: To give every AI agent its own email inbox, enabling identity, communication, and persistent memory on the internet. ## Products & Services - **AgentMail API**: REST API to programmatically create inboxes, send/receive emails with full threading, attachments, and multi-party support. Includes webhooks, WebSockets, custom domains (DKIM/SPF/DMARC), and semantic search. [agentmail.to](https://www.agentmail.to/) - **SDKs & MCP Server**: Python and TypeScript SDKs, plus an MCP (Model Context Protocol) server for AI tool integration.

[linkedin.com](https://www.linkedin.com/company/agentmailto) ## Competitive Advantages - **First-to-market for AI-native email**: Built from scratch for agent use cases, unlike legacy providers (Gmail, Outlook) that lack API-first inbox creation and impose restrictive rate limits. - **Fully managed persistent inboxes**: Handles parsing, threading, labeling, searching, and replying – agents get the same email experience as humans without building custom logic. - **Developer-first design**: Simple API key auth, no OAuth headaches, built-in permissions and guardrails, semantic search across all inboxes. - **Scalable infrastructure**: Usage-based pricing without per-inbox monthly fees, designed to handle high volumes of emails and inboxes. ## Strategic Focus - **Current priorities**: Scaling the platform to meet growing demand from AI agent builders; expanding SDK support and integrations; hiring engineering, GTM, and operations talent to accelerate product development and market adoption.

Founders have backgrounds at Optiver, NVIDIA, and Accel. [ycombinator.com](https://www.ycombinator.com/companies/agentmail) - **Remote/Hybrid**: Based in San Francisco; likely in-office given the early-stage startup nature, but not explicitly stated. - **Perks & Engineering Culture**: Competitive salary ($110K–$400K depending on role) plus meaningful equity (0.20%–2.00%).
