03STRATEGIES & TACTICS

THE NEW BATTLEGROUND IN GTM

Someone who loved your product moves to a new company. You could send the same congratulations-and-pitch email they'll get from everyone else. Or you could bring up what they actually accomplished with your product and ask whether they're tackling something similar in the new role. One workflow here waits a month before making that approach. Another reopens lost deals when the original obstacle changes, such as a budget or executive. The reason to reach out comes from what happened in the account, rather than how long it's been since the last email.

6-7 LOOPS WE USE EVERY DAY TO MAKE POSTHOG SELF-DRIVING

A bug report often starts a second conversation. What were you doing? Where did it break? Can you make it happen again? PostHog connects feedback submitted inside the product to agents that investigate and propose fixes. In one example, an investigation report arrived within five minutes, followed by a proposed code change eight minutes later. Other workflows investigate error spikes and inspect session recordings. Each step passes its findings to the next, reducing how much someone has to reconstruct before they can start fixing the problem.

04TOOLS & RESOURCES

AX

AX is a high-throughput, declarative orchestrator that runs billions of autonomous agent workloads in a cluster. Users declare an agentic task with workspaces and gateway specifications, and AX sandboxes it, wires up its workspace, fences its network, and helps run it at scale. It runs on top of Agent Substrate and feels similar to using Kubernetes.

OPENING ACCESS FOR DEVELOPERS TO BUILD MUSE CONNECTORS

Meta has opened access for developers to build Muse connectors. Developers bring the API, and Muse handles the agent, browser, and the context. To create a connector, developers need to describe the connector to Meta and explain how users will use it. The submission will be reviewed for functional, security, and legal requirements and complete end-to-end testing. Once approved, users will be able to find the connector on Muse. Meta's editors will review connectors for featured placement.

WHO CONTROLS YOUR STARTUP? WHY GOVERNANCE MATTERS FROM DAY ONE

You can own a large share of your company and still lose your job in one board meeting. That happened to Zenefits' cofounder CEO: removing him did not require a shareholder vote. Figma offers a different example, with its cofounder holding roughly 9% of the equity but just over half the voting power. This guide separates ownership, voting rights, and board control. When reviewing a term sheet, work through who appoints each director, who can replace them, and what happens to those rights in the next round.

PEOPLE FIRST EQUITY PLANS

An employee can earn stock options and still be unable to afford exercising them. Athyna designed its equity plan around that problem, setting aside 20% of the company and granting restricted stock units rather than options employees must purchase. Its plan combines time-based vesting with a liquidity event before shares transfer. Everyone receives a grant, including interns, with amounts varying by role and seniority. The company also walks employees through what they own, what happens if they leave, and how future fundraising changes their percentage.
