Who We Help

Your GTM motion is either working, or burning time. We help early-stage founders and lean teams fix what’s broken, or avoid wasting months on guesswork.

Your GTM motion is either working, or burning time. We help early-stage founders and lean teams fix what’s broken, or avoid wasting months on guesswork.

Founder-Led Teams

You’re sending cold emails, jumping on calls, and figuring it out as you go. We help you build an early GTM system, so you’re not winging it every week.

Pre-Sales Hire

Hiring a rep or contractor soon? Most fail without a system. We help you build messaging, targeting, and workflows to onboard smoothly and make success repeatable.

Unconverted Outbound

You’ve launched—but replies stall or leads vanish. We help find the leaks, fix your targeting and messaging, and lock in what actually converts.

How We Build With You

We build your GTM system with you, and not just hand you one off the shelf

Why Founders and Teams Trust GTM Nexus

We don’t just build GTM systems. We help founders ship things that actually work. Here’s what they’re saying.

"Charlie isn’t just a tactician, he connects GTM execution to the bigger picture. We brought him in to help reset our outbound motion after our first campaign failed. He ran a full audit, rebuilt our system, and narrowed our focus to a high-signal ICP: companies hiring Postgres talent. His messaging landed real traction with our first design partners, and that work became a key driver that led to our acquisition.

"We initially brought Charlie in to launch a new service, and he ended up reshaping our entire go-to-market. He rebuilt our outbound engine, clarified our messaging and helped us reach enterprise targets. He also elevated how we used our executive voice in outreach, which opened new doors. His work didn’t just drive pipeline, it reframed how we position Bredin for long-term leverage."

“Charlie helped us turn around a struggling inbound SDR workflow. Meetings were falling through the cracks, follow-ups lacked strategy, and KPIs weren’t being tracked. He advised on Salesforce workflow improvements, and revamped messaging that more than doubled weekly meetings booked. His guidance had an immediate impact on productivity.”

Meet Your GTM Partner: Charlie Rivas

Early stage founders are expected to build a company while still figuring out go-to-market: what to say, who to target, how to get traction.


But without clear benchmarks or a GTM motion that fits their stage, most are stuck guessing.


Should I hire or keep selling myself? Why is nobody replying? What does effective outreach and follow-up even look like at my stage? How do I run a first call that actually goes somewhere?


That’s why I built GTM Nexus, to give founders the clarity, structure, and momentum their early GTM motion needs.


We sharpen your message, launch in market, and co-build a motion you can run yourself or confidently hand off to your first hire.


Over the past six years, I’ve partnered with dozens of founding teams across SaaS and services. I’ve seen what happens when sales is treated like a side task, when reps are hired too early, or when messaging falls flat because it’s not grounded in what buyers actually care about.


This isn’t a lead gen shop.


I don’t rent pipeline or run scripts behind the scenes. We co-build your motion, test it live, and leave behind a system you actually understand.


I’m not a coach. I’m not a copywriter.
I’m your early stage GTM partner—until you don’t need one.
