The Person Behind the Work

I've spent my career inside
complex GTM problems.
Hart House is what I built from it.

For more than a decade, I've operated inside businesses at the hardest moment — when a company knows it needs to grow differently but doesn't yet have the system to do it. I've been the first dedicated growth hire. I've rebuilt demand systems from scratch. I've led rebrands, built pipelines, and sat across from executive teams to translate what marketing can actually do for revenue.

The companies I've worked with have been technically complex — regulated industries, infrastructure technology, enterprise SaaS with long multi-stakeholder buying cycles. These aren't environments where generic marketing advice works. They require deep positioning work, precise ICP targeting, and demand infrastructure built for buyers who take months to decide.

That experience is exactly what Series A–C SaaS companies need when they're trying to build beyond founder-led growth. The patterns are the same: pipeline that's inconsistent, messaging that doesn't convert, marketing activity that produces noise instead of revenue. The system underneath was never properly built.

Hart House is where I bring all of it. The Revenue Architecture™ is the framework I wish I'd had in every role. Now I build it for founders who are ready to stop guessing and start scaling.

The Approach

I don't audit
from the outside
and hand you a report.
I get inside the business.

Most fractional engagements are advisory at arm's length. A strategic recommendation. A slide deck. A roadmap you're left to execute without the person who built it.

That's not what this is. Every Hart House engagement is built around access — real access to the business, the team, the data, and the conversations that actually matter. I operate inside your GTM motion, not above it.

The Revenue Architecture™ is how I think about every engagement. Five integrated systems — narrative, engine, lifecycle, content flywheel, and attribution — assessed against your specific stage and gaps. Where we start is determined by where your architecture is weakest, not by a fixed playbook.

The goal is always the same: build a system that runs without me. That means documenting what we build, training your team on how to run it, and handing you a business that's stronger because of the engagement — not dependent on the next one.

How I Work

Three things that are true
of every engagement.

These aren't policies. They're the conditions that make the work worth doing — and that make it actually work.

01
I need a real seat at the table.

Not advisory access. Not a monthly briefing. If I'm building your GTM system, I need to be part of the decision-making conversations — the ones where strategy actually gets shaped, not briefed on the outcome after the fact. That's the only way the architecture reflects reality.

02
I build systems that run without me.

Every engagement ends with your team trained, your system documented, and your pipeline running on its own. Creating dependency is the opposite of the work. The goal is a business that's stronger after I leave.

03
I'll tell you what's actually broken.

Even if it's not what you asked about. Even if it's uncomfortable. The value I bring isn't agreement — it's an honest read of what the data and the system are actually saying. You can decide what to do with it.

who gets inside the business?

Every engagement begins with an honest conversation about what's actually broken — and whether Hart House is the right partner to fix it.
