• Define success metrics and check whether each release moved them.
• Run customer interviews, analyze feedback and separate high‑value insights from feature requests.

Nice to have

• Sales technology, lead generation, marketing automation, communications software or data products.
• A SaaS portfolio, startup studio or other multi‑product company.
• AI‑enabled product development and automation.
• Product‑led growth, onboarding, pricing or monetization.
• A technical background, or a strong ability to work with APIs, integrations and data workflows.
