About us
Content built for growth-stage B2B marketing teams
SeriesX Marketing is a content agency that ships enterprise-grade content and builds AI agents for your custom use cases—at startup speed. We exist because good products get stuck behind slow content ops and generic “AI” shortcuts. Our model fixes both.
Here’s what this means for you:
- Enterprise quality — senior marketing expertise, not just content writing.
- Startup speed execution — on a predictable weekly cadence.
- No extra headcount — thanks to automated ops and clear ownership, your campaigns and stakeholders are finally unblocked on growth.
About us
Why we do what we do
We started SeriesX after seeing a pattern: great products stuck behind slow content ops and generic “AI” shortcuts.
Our model combines U.S. focused marketing expertise and experienced SaaS/tech writers with startup execution speed, so you get enterprise quality and rapid turnaround—without adding headcount.
Our vision is to use our marketing expertise to make content the primary business driver for the world’s fastest-growing B2B companies.

Meet Our Chief Pawficers 🐾
At SeriesX, we believe no team is complete without emotional support, walk reminders, and the occasional tail-chasing chaos. Meet our unofficial co-founders:
Chief Happiness Officer
Tasha
Part golden soul, part couch therapist. Tasha’s job is to remind us to pause, breathe, and occasionally roll in the grass. When she’s not curled up next to your laptop, she’s supervising secret snack breaks and interrupting serious talks for mandatory serotonin boosts.
Chief Duty Officer
Wanda
Firm but fair, Wanda ensures meetings start on time (or else you’ll get the suspicious side-eye). Known for her strategic pacing during team calls, sniff-vestigating guests, and a strong stance on boundaries (especially break-related), she brings structure, sass, and a little wiggle to our workflow.
Our writer bench
Our 5-person writing team brings ~25 years of combined B2B experience across MarTech, HealthTech, IT services, FinTech, and more. Every draft goes through a two-layer edit (line edit + fact check) and on-page SEO optimization before it ships.
