How we helpTurn growth ambition into action, with marketing foundations that scale.
Strategy & GTM
Turn ambition into a repeatable roadmap. Stop guessing which channels work. I help build GTM frameworks, define positioning and lead new market expansions, so your marketing directly supports your revenue goals.
CRM & Lifecycle Operations
Turn leads into pipeline. Marketing is useless if leads don’t convert. I specialise in building CRM-driven nurture journeys and automated workflows that have historically contributed up to 33% of total pipeline.
High-Performance Execution
Demand generation that drives pipeline. From paid search and social to events and thought leadership, I run campaigns that build brand authority and have generated $250K+ in partner-led revenue.

Why SGA?Senior marketing leadership, without the full-time hire.
I’m Matty Sirois, founder of SGA. I’ve spent the last decade as the first senior marketing hire for high-growth companies. I don’t just hand over a slide deck of advice. I roll up my sleeves to build the systems, manage the teams and lead the strategy that gets you to your next goal, whether that’s a funding round, a new campaign launch or just getting off the ground.
