I'm Mash — 25 years, four exits, and a track record of turning stalled ideas into real, self-sustaining companies. I work with growth-stage founders to sharpen the decisions that actually move the business.
Not enough leads. Messaging that doesn't land. A funnel that leaks. They look like marketing problems — but underneath, they're almost always strategy problems: unclear positioning, a fuzzy customer, no real focus. Fix the root and the symptoms take care of themselves. That's the work I do — improving the quality of the decisions the whole business rests on. It's the idea behind my book, What Holds Up the Roof.
Senior, judgment-first guidance on the decisions that move a business forward — not tactics for their own sake.
Get crisp on what you are, who you're for, and why you win — so everything downstream gets easier.
Replace anecdotes and assumptions with real discovery, so decisions rest on evidence, not hunches.
Say the thing that makes the right people lean in — and stop trying to talk to everyone.
A focused motion that fits your stage and market, instead of scattered activity that burns cash.
A trusted thought partner in your corner, so you make faster, better calls with less second-guessing.
Turn one-off wins into repeatable systems the business can run without depending on any one person.
Senior marketing leadership without a full-time hire. I set the strategy and own the growth — while my team and AI tools do the heavy lifting — so you get a real go-to-market engine at an early-founder price.
I've co-founded and scaled four startups to successful exits, advised three companies to billion-dollar outcomes — an IPO, a merger, and a private-equity deal — launched a startup incubator at San José State University, and taught thousands of business students as an adjunct professor. My whole career sits at the intersection of innovation, strategy, and execution — the throughline of my book, What Holds Up the Roof.
And these days a visible body of work beats a resume — it's evidence, not claims. So I help founders build both: the business, and the reputation that makes people trust them before the first conversation.
My book What Holds Up the Roof is a business fable — the four principles of entrepreneurship, drawn from 25 years of building and advising, told through a founder learning what actually keeps a business standing when the plan falls apart.
