The Reality
You're moving fast.
GTM clarity
is hard at speed.
The best cybersecurity and AI startups aren't unfocused — they're racing forward on multiple fronts simultaneously. That speed creates a very specific set of GTM gaps.
Vision drives startups forward. But a vision that outruns the current market — or a product built for where buyers will be, not where they are today — creates a gap that strategy and execution have to close.
Competing priorities crowd out GTM
Product, engineering, fundraising, hiring — GTM strategy gets squeezed to the margins. Without dedicated focus, go-to-market becomes reactive instead of intentional.
Vision ahead of market readiness
Your roadmap is built for where the market is heading — but buyers are making decisions based on where they are today. Bridging that gap requires a different kind of message.
Unclear buyer pain hierarchy
You know your technology solves real problems — but you're still learning which pain points drive buying decisions, who owns budget, and what actually triggers an evaluation.
Sales and marketing out of sync
When positioning, content, and sales motions aren't built from the same foundation, pipeline suffers. Deals stall because the story doesn't hold end-to-end.
These aren't just growing pains.
They compound.
Every quarter without a defined ICP, your team chases accounts that will never close. Deals your competitor lands. Every new sales hire inherits the confusion. And amplifies it.
Runway doesn't pause while you figure out GTM. Neither does your market.
What We Do
Three pillars.
One integrated outcome.
We don't hand you a slide deck and disappear. We embed with your team and build the systems, strategies, and content that generate real pipeline.

Who We Serve
Built for the sectors
we know deeply.
We're not generalists. Our expertise lives at the intersection of emerging tech and complex enterprise buying cycles.
Cybersecurity Startups
From Seed to Series B, we help cybersecurity companies cut through a crowded market with messaging that resonates with CISOs, security engineers, and procurement teams. We understand the nuance of selling trust in a zero-trust world.
AI & ML Companies
AI is everywhere — which means differentiation is harder than ever. We help AI startups define their unique value, educate the market, and build demand programs that convert curiosity into qualified pipeline.
The Team
The people behind
the work.
Deep operator experience across marketing, sales, and go-to-market — built inside the industries we serve, not learned from the outside.
Marc Brown
Co-Founder & CEO
Marc brings deep marketing and GTM leadership experience built inside cybersecurity and AI companies. He has built marketing organizations from the ground up — defining positioning, launching demand generation engines, and scaling programs that drive real pipeline and revenue. Marc founded Aterous Group to give early-stage companies access to strategic marketing and sales expertise typically reserved for larger organizations.
Lina A.
Co-Founder & CMO

Why Aterous
Operator experience.
Zero fluff.
We've built and led marketing and sales organizations inside cybersecurity and AI companies. We know what works — and what looks good in decks but fails in the real world.
Deep sector expertise
We speak cybersecurity and AI fluently. No ramp-up time — we understand your buyers, competition, and market dynamics on day one.
Right-sized for startups
We build what you can actually execute with the team and budget you have today — not what a Fortune 500 marketing org would do.
Strategy + execution
We don't just advise. We deliver — content, campaigns, HubSpot builds, playbooks, and programs that actually launch.
Integrated across sales & marketing
Marketing without sales alignment is noise. We ensure your entire revenue engine is working from the same playbook.
Real expertise. Not recycled AI output.
We use AI like every modern team does — to move faster and deliver more value. But what we bring you is purpose-fit strategy built from genuine human expertise in your market.

Sarah M.
VP Marketing, AI Security Startup
"We hired Aterous to build our sales org from the ground up. Three months later we had a functioning team, a quota model that made sense, and our first enterprise deals in the pipeline."
