Lightline Lab is an independent consultancy for applied AI, product strategy and execution, and other new ventures.
My work has ranged from products used by millions of people to new AI platforms, patented advertising products, independent consumer apps, and early-stage businesses. The common thread is turning a promising idea into something real, useful, and commercially durable.
Break negative thought loops.
An independently conceived and launched consumer wellness app designed to help people interrupt negative thought patterns in the moment. Built as a real product — not a prototype — with consumer UX, privacy-safe HealthKit data, monetization, analytics, and distribution.

Remix book titles into poetry.
A social creativity app that turns book-spine poetry into a mobile creation format: make poems from book titles, share them, invite friends to remix them, browse a community gallery, and order a physical version of what you create.

Launched YMAX — an integrated platform combining AI-powered contextual curation, proprietary engagement signals, and creative optimization — and built creative optimization products using generative AI, machine learning, and human design that consistently deliver meaningful KPI lift for major clients.
Incubated and productized a patented suite of interactive advertising formats across web and CTV that became a defining part of Yieldmo's creative identity and helped underpin its attention measurement and optimization products.
Led digital product work for the 2012 campaign, building experiences that reached and engaged millions of voters.
Launched the campaign's first one-click and text-message donation capabilities, helping drive a meaningful share of a record-setting fundraising operation, alongside mobile and Facebook products designed to support turnout in battleground states.
Created Blue State's custom product practice, expanding a strategy-and-creative organization into digital product development and helping unlock seven-figure, movement-building engagements in new client verticals.
Helped launch Hashable and built self-service advertising products at Quigo / AOL — formative work in social software, product-led growth, and the systems behind scalable digital businesses.
I help teams decide what matters, turn the answer into something buildable, and stay close enough to make sure it works in the real world.
For companies with too many ideas, an unclear roadmap, a promising new opportunity, or a product that has lost its center. I help turn ambiguity into a clear product point of view and an executable path forward.
strategy · roadmap · scope · prioritization · positioning
I help teams move past demos and generic “AI strategy” to practical applications of generative AI and machine learning — new product experiences, smarter workflows, better decision systems, and prototypes that can become operating products.
assess · prototype · pilot · adopt · measure
For founders and established companies exploring a new product, market, or business model. I can work from rough opportunity through concept, product definition, MVP, validation, and go-to-market — with a bias toward getting something real into customers' hands.

“We have a good idea, but aren’t sure what the actual product is.”
“Our roadmap has become everything for everyone.”
“Leadership wants an AI strategy. We want one that produces something useful.”
“We’ve been talking about this new product for months and need to get it moving.”
“Product, engineering, sales, and customers are pulling in different directions.”
“We need senior product judgment, but not necessarily another full-time executive.”
Creative product leader
A couple of decades launching creative and technology products across advertising, media, politics, consumer software, and AI.
A whimsical career path had the happy side effect of wiring me for the multi-disciplinary. It's how I help teams excel at products that tell stories or move people to action. How might we make our next project do both?
New York City · available for selective advisory and consulting engagements
Bring one real product, AI, roadmap, positioning, or go-to-market problem.
We'll spend 30 minutes working on it — not talking about working on it. I'll give you my read, challenge assumptions that need challenging, and help you leave with a clearer decision and concrete next steps.
No pitch required. No ongoing engagement expected.
If you're exploring a larger product, AI, or new-venture engagement, send me a short note. You don't need to write a brief — a few sentences about the opportunity or problem is enough.
