Product & PLG Lead

Location: San Francisco, CA

Type: Full-time, on-site

Agent Mail is building the communication and identity layer for AI agents.

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. Agent Mail 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 Hub Spot
, 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.

We're hiring a Product & PLG Lead to understand who uses Agent Mail, why they need it, where they get stuck, what makes them activate, and how product usage turns into expansion.

This role owns the product-led growth loop. You'll work across Post Hog, customer calls, onboarding flows, docs, API usage, lifecycle emails, and experiments. Your job is to understand what people are building with Agent Mail, which use cases matter most, and how to get more users to value faster.

• Own product analytics across Post Hog and related tools
• Build dashboards for signup quality, activation, retention, expansion, churn, and PLG-to-sales conversion
• Segment users by persona, use case, company type, behavior, API usage, and revenue potential
• Run A/B tests across onboarding, docs, lifecycle emails, pricing, packaging, and activation flows
• Identify which API features and use cases drive the strongest retention and expansion
• Interview customers and translate usage into clear personas and product insights
• Build lifecycle campaigns that help users get to value faster
• Partner with engineering to improve docs, examples, templates, SDK flows, and first-run experience
• Partner with revenue to identify high-intent accounts and expansion opportunities

• You are obsessive about funnels, product behavior, event tracking, and user intent
• You have worked on PLG, growth, product, analytics, or lifecycle at a technical product company
• You know tools like Post Hog, Amplitude, Mixpanel, Segment, Customer.io, SQL, Hex, Metabase, or similar
• You can form a hypothesis, instrument it, ship an experiment, and interpret the result
• You care about developer experience and business outcomes
• You can talk to users and also inspect raw product data
• You notice tiny product and messaging details that others miss
• You are comfortable with ambiguity and can create structure from messy usage patterns

• Experience with developer tools, APIs, infra, AI products, or B2B PLG
• Experience turning self-serve users into sales-qualified accounts
• Experience with pricing/packaging experiments
• Experience building onboarding, docs, lifecycle, or activation systems
• You can write clear product copy and explain technical concepts simply
