Break through your next growth plateau — in a market being rewritten by AI.

I help founder-led B2B companies — software and service-enabled — find the highest-leverage path to growth and navigate the shift to an AI-driven market.

20+ Years in B2B

Growth rarely stalls from a lack of effort. It stalls when effort isn’t aimed at the one priority that actually moves it — and AI is raising the stakes on getting that right.

You’re generating opportunities, but something is getting in the way: positioning, sales conversion, onboarding, retention, focus, or execution. Meanwhile the ground is shifting — AI is compressing distribution, changing how buyers discover and switch, and punishing fuzzy positioning.

I help founder-led B2B companies find the one real constraint, build the focus and systems to fix it, and make the right strategic calls in an AI-driven market.

Over the past 20 years, I’ve advised 300+ founders and CEOs and helped companies:

• Increase new MRR by 400%

• Grow ARR by 80%

• Cut sales cycles in half

• Win six-figure enterprise customers

• Build traction for U.S. expansion

No generic playbooks. Just clear priorities, hands-on execution, and measurable growth.

Let's see if we're a fit

Clients I Work With

I work with founder-led B2B companies in the $500K–$20M range — both SaaS and service-enabled businesses: agencies, IT and managed services, recruitment, professional services,and tech-enabled service firms.

The common thread isn’t the industry — it’s the moment. You’ve built something real, growth has stalled or become unpredictable, and the business increasingly runs through you. That’s the wall I help founders break through.

Services

Revenue Growth

When growth slows, the instinct is to add — more marketing, more outbound, more tools, more salespeople. But the highest-leverage move is usually understanding what’s already happening. Often it’s not a lead problem — it’s a visibility problem. I help founders find the one real constraint, then build the systems, motion, and accountability to fix it — using AI where it creates real leverage, not noise.

GTM Execution

Strategy without execution is just a plan. I work alongside founders and their teams to sharpen positioning, improve sales conversion, optimize current acquisition channels, build new ones, and create the repeatable GTM motion — including funnel optimization — needed to grow beyond what's working today.

Customer Retention & Expansion

Acquiring customers is only half the equation. I help companies get clear on their customer journey, optimize activation, reduce churn, and build intentional systems for expansion revenue — turning existing customers into a compounding growth engine.

U.S. Market Expansion

Breaking into the U.S. market requires more than replicating what worked at home. I help European and Canadian companies define the right ICP, adapt positioning for a US buyer, build local traction, and establish the commercial foundation for sustainable growth in North America.

Growth in the AI Era

“When execution gets easier, the bottleneck becomes how your growth engine is designed — not how hard your team works.”

AI doesn’t kill good businesses. But it punishes fuzzy positioning, bloated roadmaps, and go-to-market built for a slower world. It compresses distribution, lowers switching costs, and makes buyers far less patient with “eventual” value.

The founders who win aren’t bolting AI onto the old model — they’re rethinking where to focus, what to build, and what NOT to automate. That takes judgment, not just tools.

I help founders make those calls: where AI creates real leverage in your growth engine, where it’s a distraction, and how to build a business that compounds rather than one that just moves faster in the wrong direction.

How It Works

Step 1

Discovery

Before setting priorities, I need to understand the business deeply — revenue composition, growth engine, funnel, pricing, customer journey, and where the real constraints are. Month 1 is dedicated to this.

Step 2

Strategy & Priorities

Together, we identify the highest-leverage opportunities and build a clear set of priorities. Not a 20-point plan — a focused set of bets that will actually move the needle.

Step 3

Ongoing Partnership

A standing weekly call, direct async access between sessions, and hands-on involvement in decisions, initiatives, and execution as priorities evolve. Flexible by design, built around what matters most.

This is a retainer engagement — month-to-month, no fixed scope. Priorities shift. The partnership flexes with you.

Success Stories

“We were facing significant challenges with customer acquisition costs, sales quality, and turnover within our inside sales team. The economics of the business were becoming increasingly difficult. Julien helped us take a step back and identify practical ways to improve our close rates and overall sales effectiveness. Together, we implemented several important changes, including improving our pricing and packaging strategy, refining our sales scripts and best practices, and redesigning compensation to attract and retain higher-quality sales talent. The impact on the business was significant. Our LTV-to-CAC ratio improved from the high 2s to the high 3s and, at times, exceeded 4.0, fundamentally improving the economics of the business. Beyond his knowledge and insight, what I appreciated most about working with Julien was his genuine, collaborative approach. He is thoughtful, pragmatic, and focused on helping teams execute meaningful change.”

— Luke Ford, CEO, My Computer Works
“When I first started working with Julien, we were approaching £800k and needed to reach £1M ARR. The business heavily relied on a team at max capacity. Julien helped me remain focused on the annual and quarterly objectives — the cadence and rhythm of running a software business. Our conversations consistently enabled me to think through a different lens, enhancing our proposition, our pricing, and frameworks we could build upon. Not only with confidence, but knowing we had established the right foundation to scale further. I would definitely recommend working with Julien for his empathetic ear, as well as the tactical advice and vision you sometimes don’t know you need.”

— Ben Scholes, Founder, Papertrail
“What stood out most about Julien was that he didn’t come in with generic advice. He took the time to truly understand our business, our constraints, and the realities of building and leading a growing company. He listened, asked thoughtful questions, and brought empathy to both the business challenges and the personal pressures that come with owning and leading a company. He became a trusted partner, not just an advisor. His guidance helped us build a focused go-to-market plan, prioritize the right opportunities, and create accountability around execution. As a result, we exceeded our expectations and reached important milestones much faster than we anticipated. If you’re looking to accelerate growth without having to learn every lesson the hard way, he’s someone you want in your corner.”

— Corey Luckow, CEO, Zumasys
“Julien came in at a point when we were losing clients and getting almost no uptake from new prospects — a genuinely tough spot for the business. He helped us reset our pricing to something realistic and sustainable, and coached our team on the sales conversations needed to actually close. Both made a tangible difference. What sets Julien apart is that he works at both levels: the big-picture strategy of where the opportunity lies, and the granular detail of how to execute it. I’d recommend him to any founder looking for that combination.”

— Tom Aune, Founder & Director, Suremploy Pty Ltd
“Julien goes beyond giving advice. He leverages his experience and strategic thinking to maximize results. Execution becomes much easier when you have a partner with the experience and practical next steps to move your business forward.”

— Jay Temaat, Founder, Agency Rhythm
“Julien helped me build the organizational foundation to step back from execution and focus on what mattered most. He didn’t just give advice — he helped us actually implement it. I’d recommend him to any founder who’s built something meaningful and is ready to build the team and systems around them to take it to the next level.”

— Geoff Lilienfeld, Founder & CEO, Wise Pelican

I help founder-led B2B companies break through growth plateaus.

Over the past 20 years, I’ve worked with founders and leadership teams on revenue growth, GTM execution, pricing, retention, channel development, and international expansion.

As Former Head of Coaching at SaaS Academy, I advised more than 300 founders and CEOs — from early-stage startups to companies exceeding $50M in revenue.

The hardest stage of growth isn’t speed — it’s the transition from founder-led momentum to system-led scale. That’s the work I do: helping founders find the one priority that matters, build the structure that lets progress compound, and get out of their own way so the business stops running entirely through them.

I often work as a Fractional CRO, but my role frequently extends beyond sales and marketing — into whatever the highest-leverage path to the next stage actually requires, including how to grow in an AI-driven market.

Based in New York. Working with founder-led B2B software and service-enabled businesses in the $500K–$20M range.
