Bio

Mark Sylvester builds AI-backed systems for creative agencies, operators, and small businesses.

Mark is a content creator, small business owner, and consultant with 15+ years of business and entrepreneurial problem-solving experience, plus 10+ years in content, production, cinematography, photography, and design. His work is shaped by a lifelong interest in science fiction, technology, and the deeper systems that make creative tools feel possible.

He grew up on Long Island and moved into New York City to get closer to culture, philosophy, and the kind of people who were always making their own worlds. That instinct started early through music: playing in bands, producing, touring, and paying as much attention to the systems behind the show as the performance itself, including PAs, EQs, signal processing, effects pedals, tube amps, and lighting.

Across his tenure at Speakly and through work with NYC and Brooklyn creative agencies, Mark has managed 3- to 5-person teams through seasonal sprints and multi-year working relationships. His leadership style is built around systems thinking, empathy, and leading by action once planning is complete: clarify the problem, give the team a workable structure, then move with the work until the output proves the plan.

Over the last five years, his work and research have centered on AI, LLMs, systems engineering, AI-SEO, and web design, with a specific goal: understanding how these tools can solve niche creative agency problems. He built Speakly Media’s AI-SEO system and Sidecar, a customer project management and roadmap app for turning client work into clearer goals, visible progress, and repeatable delivery. He is also researching custom-trained models and agentic workflows for both platforms. Outside client work, he still tinkers with electrical and structural engineering ideas, small woodworking projects, and the practical mechanics behind how things are built.
