Our Team

Part strategist, part operator. Embedded in your business to drive profitable growth

Founded by senior ex-Meta leaders, with nearly a decade inside the most measurement-forward advertising organization ever built.

Yoni Levy

Yoni Levy

Co-Founder

Yoni spent two decades turning marketing from a cost center into a measurable sales engine. As Head of DTC and Ecommerce Canada at Meta, he led a team of growth consultants with a $350M+ annual advertising portfolio. He was embedded in the strategic decisions of founders at high-growth startups and marketing leaders of Canada’s largest brands, companies with $100M to over $1B in revenue.

That stage is where measurement breaks, channels multiply, and the tactics that built the brand stop working. He helps brands build what comes next.

The Problems We Solve

The playbook that got you here won't unlock your next stage

You've built something people want. Your product and early marketing strategies created real momentum.

Now acquisition costs are rising, channels are multiplying, and measurement is misleading you. The problem isn't effort. It's knowing what's actually working and where the next dollar should go.

You need a partner who’s obsessed over your growth and knows how to drive it.

What We Build

A system that drives profitable growth, grounded in incrementality

We don't hand you a strategy deck and disappear. You set the priorities, we build the plan. Then we execute like operators alongside your team.

Growth Strategy + Prioritization

Identify where the next stage of growth comes from, across markets, channels, and products. Then build the plan to get there.

Measurement + Decisions

Calibrate your measurement system so incrementality, attribution, and MMM lead to clear decision making.

Media Allocation

Map where budget should move, where efficiency is hiding, and where scale is constrained.

Creative + Conversion Funnels

Turn customer, competitive, and performance insights into briefs. Test the hooks, messages, formats, and landing pages that convert.

Performance Testing

Design and prioritize an experimentation roadmap so learning compounds and informs your next move.

Demand + Peak

Align investment to inventory positions, seasonal peaks, and margin targets.

Team + Rhythm

Upskilling teams, partner selection, hiring support, and codified playbooks that outlast us. And whatever else is in the way.

Everything above, plus owning the day-to-day: media buying, deeper creative & funnel testing, measurement & tracking management, partner onboarding, and more.

Who We Build For

Businesses with traction, complexity, and opportunity

Businesses at this stage:

  • $100M+ in annual revenue
  • At an inflection point. You’ve hit a ceiling, or complexity is outpacing growth. You need a team that’s been here before.
  • Hiring for senior marketing leadership, and you need the system built while you run the search
  • Frustrated with partners who only push buttons in-platform instead of building new strategies that move the business
  • Ready to invest in measurement infrastructure, not just media spend
  • Looking for a partner who operates inside the business, not outside it

If this sounds like your business, we should talk.
