The situation

You are a senior PM advising David Cramer as Sentry shifts from a popular open-source project into a real business. The product already has strong grassroots adoption, with engineers using the self-hosted version inside many companies, including large tech firms. A newly launched hosted cloud version has started getting organic paying customers, which suggests real demand, but the path to scale is unclear. The hard part is that many of the biggest current users have the engineering talent to keep running Sentry themselves, so they may never pay for cloud. Some large companies are asking for paid on-prem or support contracts. At the same time, several error monitoring competitors exist, and one is beginning to gain traction in a specific developer community that matters for future growth. The team is small, there is no mature sales motion, and community trust matters. Assume the hosted product has early revenue, most enterprise users are still self-hosting, and the team can support only one primary go-to-market motion over the next 12 to 18 months. What should Sentry prioritize, and why now?

What to produce

Write a 2 page go-to-market strategy memo.

Your answer must

State one clear recommendation for Sentry's primary go-to-market motion for the next 12 to 18 months.
Define and prioritize target customer segments, including which current users to pursue now, which to defer, and why.
Recommend a monetization and packaging approach that addresses the tradeoff between hosted cloud, self-hosted open source, and enterprise support or on-prem requests.
Explain how open source and community goodwill should function in acquisition, activation, and competitive positioning.
Describe how Sentry should respond to a rival gaining traction in an important developer community, including specific actions and success metrics.
Call out major risks, second-order effects, and the indicators that would cause you to revisit the plan.

Constraints

Sentry's open-source product and community reputation are strategic assets, so any plan that depends on cutting off the community is not acceptable.
Most large existing users can self-host successfully, so near-term enterprise conversion is structurally limited.
The team is small and cannot build multiple new sales motions or heavy enterprise customization in parallel.
There is no evidence of a large paid marketing budget or a mature enterprise field sales team.

Format

Use sections titled recommendation, target segments, monetization and packaging, role of open source, competitive response, rollout and metrics, and risks.
