Why JAC Growth

10+ Years Scaling B2B Brand Marketing

Most marketing demand gen agencies run the same playbook for every client and hand it off with no context.

I've spent over a decade helping B2B SaaS brands build pipeline from scratch. This agency combines my experience scaling companies from startup to IPO with modern AI-assisted systems to help you scale faster.

Your team gets hands-on guidance, peace of mind, and most importantly, results.

"I worked with Jared for close to 6 years where he was Marketing hire #2. Jared shines in the 'building' phase of a team that needs to cover a lot of ground with resourcefulness. One of Jared's email programs consistently saw 40–50% open rate on 30k emails, which is off the charts of SaaS/B2B benchmarks. Jared is passionate about all things Marketing, SaaS, tech and is simply an all-around good human who is a pleasure to work with."

FAQ

Common Questions

Why did you start JAC Growth?

Series A and B founders kept hitting the same wall: real pipeline problems but not enough runway to justify a VP Sales, SDR team, and copywriter all at once. They'd cobble it together or hire a generic agency running the same template for every client. Neither worked. JAC Growth gives you the full outbound function without the overhead.

What does working with you look like?

You work directly with me, not a junior account manager. 30-day ramp to get your ICP defined and sequences live, weekly iteration on what's working, and transparent reporting so you always know what's running and why.

Who is this for?

B2B founders and small sales teams — typically Series A to C — who need consistent outbound pipeline without building a full in-house function. If you're spending too much time prospecting and not enough time closing, this is built for you.

How is this different from hiring an agency?

Most agencies hand your account to a junior SDR and run the same playbook for every client. You get me — someone who's been inside SaaS companies at your stage — plus AI-powered research and sequencing that's built around your specific buyer, not a template.
