    Fractional Growth Leadership for Startups with Early Product-Market Fit Validation

    Your product is in market, and you've found early evidence that some customers consider it a must-have. The next step is understanding who those customers are, when they experience that value, and how to reach more people like them.

    I work with founders of early-stage consumer, prosumer, and self-service B2B startups. Together we look at how people discover the product, reach its value, keep using it, and bring in others.

    Building a Growth Engine, Not Just Running Campaigns

    I don't see growth as just marketing. The product promise, first experience of value, retention, and referrals all affect each other. That's how I approach fractional growth roles, workshops, and speaking.

    Fractional Growth Leadership

    Build the growth engine before you scale it.

    First we figure out why customers value the product and where new users get stuck. Then we work on the biggest bottlenecks and build a regular process for testing improvements.

    The Startups I Work Best With

    You don't need fully established product-market fit. You do need evidence that a specific group of customers considers the product valuable enough to miss if it disappeared.

    Stage

    Typically seed to Series A, with a live product, early PMF validation, and a lean, founder-led team.

    Business Model

    Consumer, prosumer, or self-service B2B products with the potential for high-velocity, low-friction growth.

    Growth Challenge

    Some customers value the product, but activation, retention, and referrals aren't reinforcing each other yet.

    Not quite sure where you stand on PMF? Strengthening that validation can be part of our work together.

    About Me

    Growth Expert & Industry Pioneer

    I coined the term “growth hacking” in 2010, based on the approach I'd used to drive growth at LogMeIn and Dropbox. At LogMeIn, I helped scale the business to a successful IPO. At Dropbox, as its first marketer, I helped grow the user base by 1,000% in six months and helped design its referral program.

    I co-authored Hacking Growth, a global bestseller with over 800,000 copies sold worldwide. The book has helped shape how teams at companies like TikTok, Microsoft, and Nubank approach growth. Today, I put these lessons into practice through fractional growth leadership, workshops, and keynotes.
