Product & Platform Leadership for Engagement & Scale
Gaming • Spatial/XR • EdTech • Consumer AI • Wellness
I help early-stage companies build products people actually want to return to.
Where engagement becomes loyalty, users become fans, and growth doesn’t require compromising values.Most companies don't fail because the product breaks.
They fail because early design decisions quietly become permanent once people start relying on the system.That moment, when momentum is real and reversibility starts to disappear, is where I do my best work.I focus on designing participation, trust, and incentives that still feel good to live inside after scale.
When Companies Reach Out
Leadership typically calls when they're about to:• Move from pilot to broader use and decisions are hardening
• Commit to a direction ahead of a board or funding milestone
• Scale into youth, education, or trust-critical environments where mistakes have consequences
• Launch publicly and credibility matters
• Address retention stalls even though early traction looked strongThe technology usually works.
What breaks is trust, participation, and community once real people start depending on the system.When systems stop feeling fair, clear, or human, adoption quietly erodes, even if usage metrics still look fine.
What I Do
Most engagements start here:
A short, focused diagnostic (typically two weeks) to pressure-test how people experience agency, trust, and participation before scale hardens decisions.You get clarity on:
• Where growth will stress behavior, trust, and credibility
• Which assumptions won't survive real-world use
• What to lock, delay, or redesign before reversibility disappearsThe goal is not more insight.
It’s confidence about what should become permanent next.From there, we decide whether ongoing fractional leadership or advisory support makes sense.
How I Work
Fractional Product Leadership
2–3 days per week, integrated with your team. Focused on product strategy, engagement design, and navigating growth inflection points where early choices lock in long-term behavior.Strategic Advisory
Monthly engagement for founders making critical decisions around engagement, retention, community, and scale.Project-Based Engagements
Focused work on specific challenges, including retention design, community architecture, youth product safety, and AI systems that still feel human.
Methodology
My work is guided by a system I call Resonant Design.It focuses on designing products and platforms where user agency, system incentives, and long-term trust stay aligned as scale increases.In practice, this means building systems people choose to participate in, where rules feel fair, incentives make sense, and engagement compounds instead of degrading after launch.
Focus Areas
• Engagement and retention (without dark patterns)
• Community architecture and fandom design
• Gamification and intrinsic motivation
• Youth-facing products (trust, safety, agency)
• AI and emerging platforms (human-centered design)
• Products navigating pilot-to-scale transitions
• Resonant Design: building products where rules feel fair, incentives align, and trust compounds after scale
Background
I've spent 20+ years building consumer systems used by millions across games, media, and emerging platforms, where voluntary participation was the only moat that mattered.Experience includes:• Games and media platforms, including Marvel and Roblox
• Spatial computing and AR/VR, including location-based AR gaming and wearables
• Neurotech, smart glasses, and biosensor-driven systems
• Youth empowerment and community systems
• Multiple platform transitions: mobile, social, AR, spatial, AIIn these environments, systems fail fast when:• Rules feel unfair
• Incentives misalign
• Trust erodes
• Participation dropsOver time, I learned that as systems become relied upon, the nature of participation changes, and the ones that last are designed with that transition in mind.I've seen promising products become durable platforms.
I've also seen them quietly collapse into costly rewrites.The difference is rarely the technology.
It's whether the right dynamics were designed early enough.
Industries & Stage
Industries:
Gaming, Spatial Computing/XR, EdTech, Consumer AI, Media and Entertainment, Creator Tools, Youth Platforms, Health and Wellness TechStage:
Typically Seed through Series A. Companies with traction beginning to scale, or pre-launch products operating in trust-critical environments.
Let's Talk
If you're navigating a moment where momentum is building and decisions are about to harden, let's talk.First conversation is exploratory.
If it's a fit, we'll move forward.
