• Design and execute targeted events and programs for VC portfolios -  help create Demo Days, office hours, workshops, and facilitate founder dinners that provide genuine value
• Extend and adapt foundational product marketing messages into fully-developed, startup-specific campaign materials—including creating slides, email copy, technical content, and sales enablement materials with minimal guidance
• Define success metrics and drive continuous optimization—establish KPIs, build dashboards, conduct A/B testing, own pipeline contribution and conversion rates
