Selected Work
Intermark Group
Intermark Group
Full-service advertising agency
An agency needed an owned content engine that could generate measurable inbound demand.
Context

Intermark Group is a full-service advertising and marketing agency with healthcare and financial services clients. The agency had no structured editorial calendar, minimal organic search traction, and no YouTube presence when the work began. The mandate was to build a content program that would generate consistent visibility, support client acquisition, and reinforce the agency's positioning as a science-backed marketing partner.

Solution

David built and managed the content strategy across the agency blog, social media channels, YouTube, and a recurring webinar series, using Semrush to guide editorial decisions. He created the CMO Minute and Ad Psych Series formats and managed production timelines across concurrent programs. His work grew organic blog search traffic 475% year over year and YouTube viewership 403% year over year, scaling the channel from zero to 40,000 annual viewers.

Paradromics
Paradromics
Clinical-stage brain-computer interface company
A clinical-stage neurotechnology company needed credibility in a market dominated by consumer tech hype.
Context

Paradromics is developing a fully implantable brain-computer interface for patients with ALS and locked-in syndrome. The content challenge was establishing clinical credibility at a time when Neuralink was generating the bulk of mainstream coverage. Clinicians, biotech investors, and payers demanded evidence of durability, safety, and de-risked execution.

Solution

David led content strategy across YouTube, LinkedIn, and X, repurposing leadership interviews into platform-native assets and growing the YouTube channel from zero to over 200,000 annual views. He built a Generative Engine Optimization strategy that positioned Paradromics as the leading developer in AI-generated responses across Perplexity, Gemini, and ChatGPT. The program drove a 215% increase in web traffic and a 362% increase in social engagement.
