About ScaleBooster
Marketing leadership built for how companies actually grow now
ScaleBooster exists because founders kept hitting the same wall: they needed senior marketing strategy, but couldn't yet justify a full-time executive hire — and the execution underneath that strategy needed to move faster than traditional agencies could deliver.
Our Approach
We pair fractional CMO-level leadership with AI-native execution. That means you get a real go-to-market strategy and the hands-on team that can actually ship it — testing more ideas per week, iterating on messaging in days instead of months, and reporting on what matters to your board.
Who We Work With
Growth-minded businesses of all kinds — from VC-funded SaaS and cybersecurity startups building out a marketing function for the first time, to established small and mid-size businesses whose marketing decisions still bottleneck on the owner or founder.
Who's Behind ScaleBooster
Led by Horacio Zambrano
ScaleBooster is the fractional CMO and marketing advisory practice of Horacio Zambrano, a startup marketing executive with over 10 years of interim, fractional, and full-time experience across early-stage companies as CMO or Head of Product Marketing, from Seed through Series C. Before that, he spent 5 years on Wall Street as an equity research analyst covering cybersecurity and SaaS/application software companies.
Beyond a Solo Practice
ScaleBooster also draws on a vetted network of designers, web developers, and growth marketing specialists who can plug into an engagement for deeper execution support — so strategy doesn't stall waiting on delivery.
How We Operate
What guides every engagement
Strategy first, tools second
AI and automation are execution multipliers, not a replacement for a clear strategy. We start with the plan, then use the fastest tools to run it.
Revenue over vanity metrics
Every recommendation ties back to pipeline and revenue impact. If a metric doesn't move the business, it doesn't make the report.
Right-sized engagements
We scope every engagement to your actual stage and budget — not a one-size-fits-all retainer.
