Gabriel Santiago

Marketing & copywriting portfolio

I turn complex software into copy that sounds like a person wrote it — and that search engines and LLMs can actually find.

Product marketer and writer with six years across early-stage software companies. I build the messaging, web pages, email programs, and GTM systems that make technical products easier to understand and sell. Currently the sole marketer at Catalyzer; previously at Prometheus Group, Feathr, and Beacon Talent.

Selected copywriting works

Things I’ve written, designed, and shipped.

Live feature pages, brochures, one-pagers, and full website rebuilds — every piece below was written and designed by me, end-to-end.

What I do

A T-shaped marketer who connects the pieces.

The work I’m hired for tends to live at the intersection of these three things.

Human-voice copy

Website pages, feature pages, brochures, and emails written for trust and clarity — not jargon. I’ve built and maintained brand voice guides used across marketing, sales, and product.

SEO & AEO mechanics

I balance keyword strategy with prose that doesn’t read like SEO sludge. I’ve built AI agents wired to Search Console, SEMrush, and analytics to surface keyword opportunities and shape long-form briefs structured for LLM and search discovery.

Email, lifecycle & segmentation

End-to-end email program ownership in HubSpot — template builds, list logic, persona-based drip sequences, and journey mapping across 5+ buyer segments. Comfortable in Pardot/Marketo-style automation logic.

About

A bit about me.

Portrait of Gabriel Santiago

I’m a product marketer and copywriter based in Raleigh, NC. For the last six years I’ve worked at early-stage software companies in roles that intentionally wear multiple hats — messaging and positioning, web and email, sales enablement, and the marketing ops that hold it all together.

Right now I’m the sole marketer at Catalyzer (EIC), where I created and maintain the unified brand voice and messaging guide used across marketing, sales, and product, defined positioning and feature-level value props for the SaaS platform, and launched a website refresh that contributed to ~20% MoM web traffic growth.

Before that: Demand Gen at Prometheus Group (owned GTM across webinars, email, direct mail, and partners; rebuilt the webinar program to drive a 20% pipeline-value lift in six months), Senior Digital Campaign Manager at Feathr (50+ client campaigns with CTRs consistently above benchmark), and RevOps / Marketing at Beacon Talent (full website rebuild, sales enablement collateral, and the underlying campaign ops).

I get the most energy from sitting with subject-matter experts, learning what they know, and translating it into copy and frameworks that make a complex product feel obvious.
