Product-led leadership for companies at an inflection point.

When the plan stops fitting the market, we reset product and growth strategy, get the team moving on it, and leave behind a system your people run after we go.

Mamet & Co. is Matthew Mamet's firm: fractional product and growth leadership, backed by a senior roster and an AI operating system that ships with the team.

Problems we solve

Strategy

"Our plan no longer fits the market."

Growth stalled, a pivot, or a new investor thesis.

We reset the strategy and the roadmap that carries it, in weeks, not a planning cycle.

Leadership

"Our team lacks direction."

The team outgrew its leader.

We set the direction, coach the leader or fill the seat, and the team stops waiting on decisions.

Organization

"Every department runs its own plan."

Teams are busy, but the work doesn't add up.

We put every team on one plan, with one set of priorities and clear owners.

Operations

"Our delivery is slow and unpredictable."

Dates slip, and nobody can say why.

We install an operating cadence and the measures that show progress every week.

How we engage

Fractional exec · Month to month

Senior leadership in the seat now

An interim or fractional CPO or CGO who owns the decisions, without a full-time hire. Matthew with your team, on a monthly retainer.

Focused sprint · A few weeks

Something is broken. Find it and fix it, fast.

A defined problem, a fixed fee, and a few weeks. Us working alongside your team.

Dedicated team · Sized to the bet

A big bet, without pulling your core team off the business

Mostly us. A blended team takes the bet from strategy to shipped product. A solo advisor cannot offer this model.

Every engagement starts with a two-week assessment.

A written read on what is slowing the plan down and what to change first. You own it outright, whether or not you hire us.

Not the royal we.

Every engagement is led by Matthew. Behind him is a standing roster of senior specialists, used as needed - engagement after engagement. They already know the playbooks and tools, so they're productive from the first week instead of the fifth. You get one principal's judgment with a team's output.

Matthew runs the strategy on every engagement, start to finish. No hand-offs.

AI in production, not in a pitch deck.

Your team gets working AI agents and the runbooks to run them from week one, and keeps both when we leave. It is the same system this firm runs on every day, with agents for research, sales, finance and publishing under plays, runbooks and quality gates that Matthew orchestrates. It works across Anthropic, OpenAI and Gemini, so you are not locked to one vendor.

Case study · EverQuote

Putting licensed agents into the answers AI gives

Consumers now ask AI assistants about coverage, claims and price, and those answers are built from content almost no licensed agent wrote, because compliance review happens after publication. Matthew built EverQuote an AI platform that moves compliance in front of publication, as a working product outside its stack, then handed it off.

AI calls in adversarial testing, with guard interventions driven to zero before launch

for a frame-by-frame video compliance review, at a cost measured in cents

An AI interviewer turns a call with a licensed agent into a publishable draft for under a dollar.
An AI reviewer checks every piece against the carrier's own compliance rules, cites the regulation and proposes the fix. A person makes every publishing call.

About Matthew

I've spent 25 years building product and growth businesses - from zero-to-one startups to publicly traded companies across consumer, marketplace, and SaaS.

I co-founded EditMe.com and led it to exit. As President of Embarc, I doubled revenue before another exit. At TripAdvisor (NASDAQ: TRIP), I drove $100M in incremental hotel metasearch revenue in six months through A/B test-driven optimization, then built Instant Booking from zero to $200M. At EverQuote (NASDAQ: EVER), I drove $200M in incremental revenue through product strategy. At EnergySage, as CPO, I took a solar marketplace into whole-home electrification.

Along the way I've led teams of 5 and teams over 150. I've navigated board pressure, tight runways, and markets that didn't exist yet. That range is what I bring to the work.

What leaders say

Alex Grodd

Founder & CEO of BetterLesson

I've worked with many product advisors and consultants over the years, but none bring as much energy, passion, and expertise. Matthew embeds himself with the team and brings an unparalleled level of depth and personal investment. He thrives at critical moments like product pivots.

Jamie Biggar

Co-Founder & CTO at EnergySage

Matthew's sharp mind and breadth of experience make him a formidable product leader. Matthew knows how to effectively employ his deep library of playbooks both to drive alignment between company & product strategy, and to streamline team processes for clean execution.

Nathan Papazian

Chief Product Officer at Ellevation Education

Working with Matthew, the results have been incredible. Through our work, I've gained more confidence in my ability to not only influence those within my team, but also laterally and upward. I now have tools and strategies to apply to any situation, achieving things I didn't think I was capable of.

Matt Wiseley

Director Technology at Wakefly

For 25 years I have relied on Matthew as a mentor, trusted advisor and close friend. He has a rare ability to cut through the haze of culture and personalities in an organization, laying bare the truth of present circumstances and carving out a strategic path to value.

Kari D'Elia

Chief Product Officer at USAFacts

Matthew was instrumental in my progression to an executive product leader. His ability to teach first principles and solid product fundamentals, combined with his coaching on authentic influence and calculated risk-taking, provided an excellent foundation for career growth.
