The Founder Playbook newsletter achieves exceptional 50-80% open rates by focusing intensively on single topics rather than covering multiple subjects superficially. Each weekly issue tackles one actionable strategy in depth - from cold email templates to pitch deck breakdowns - providing implementable value rather than surface-level insights.

DeMars created a systematic content creation process where investors record 5-minute voice notes on topics from their daily conversations with founders. She then transforms these insights into newsletter content, leveraging the team's frontline knowledge while maintaining editorial control and consistency.

After extensive testing, DeMars found success with Toolflow AI by having the founder create a custom GPT trained on her four years of writing samples. This approach produces 80%+ usable first drafts because the AI understands her voice and style, rather than generic content that requires complete rewrites.

Rather than viewing founders and investors as competing priorities, DeMars leverages the fact that both groups want access to each other. This creates natural partnership opportunities, cross-promotional potential, and event programming that serves both constituencies simultaneously.

DeMars identified that most venture capital content reads like "Wall Street Journal" pieces when the audience needs something between that and "BuzzFeed." By simplifying language and structure while maintaining tactical depth, she makes sophisticated concepts accessible to busy operators.

Hustle Fund's virtual events focus on showing actual workflows, templates, and tactical implementations from subject matter experts rather than high-level discussions. This approach drives both attendance (40-50% show rates for free events) and brand affinity by providing immediate implementable value.

DeMars has killed multiple initiatives including podcasts, crypto education programs, and founder bootcamps when they didn't meet ROI thresholds or resource constraints. This disciplined approach to experimentation allows for rapid testing without organizational drag from underperforming programs.
