About us
Built by the marketers who couldn't find a good content agency.
SeriesX Marketing was built by marketing leaders who spent years on the other side of the agency table — briefing writers, reviewing drafts, correcting the brand voice on every round.
We built what we couldn’t find — a content function that runs without you having to run it.
We are Practitioner-led: A senior marketer oversees every account — not just an editor, not an account manager.
We offer Full-stack content as a choice: We can write copy, design assets, and include strategy in one workflow. You decide what you want included.
Human-written, fast by design: Experienced B2B writers with AI-accelerated research and briefing behind them, keep your content moving — without the weeks-long queues most agencies run.
Our Track Record
About us
Why we built this agency.
Before SeriesX, the founding team spent years as marketing leaders and buyers of agency services — at B2B SaaS companies and growth-stage technology firms.
Every B2B marketing head we have worked with was running into the same problem. The content got outsourced. The brief, the quality check, the brand voice policing — all of that stayed on their desk. Freelancers needed managing. Agencies didn’t know the buyer. In-house hires needed onboarding and direct reports needed constant management. In every case, the marketing head was still the one holding the brief, reviewing the draft, and making the quality call.
We started SeriesX to fix this: the management overhead that stays with the marketing head even after outsourcing content.
The content marketing agency we built runs differently:
- A senior B2B marketing practitioner leads every account, and learns your category like it’s their own
- Our handpicked, specialist writers and designers handle the domain expertise needed in B2B writing and visuals.
The result: a content function that runs without you having to run it.
What clients say.
Working with Tara, Divya, and the SeriesX team has been a breath of fresh air. Their attitude, energy and proactive approach are not something you always get from an external partner.
The team not only produced well-written, concise content but also kept stakeholders accountable, maintained high quality, and ensured assets reached publication. I highly recommend SeriesX Marketing for B2B content services and technology companies.
It didn’t feel like a vendor-client setup”
We engaged SeriesX to create technical blogs, case studies, and LinkedIn content — and what really stood out was the depth of research and understanding. Before writing, the team always takes the time to grasp the topic thoroughly, align with our technical experts, and shape the content to match what our audience actually wants to read.
It never felt like a typical vendor-client setup. Our conversations go beyond execution — we regularly collaborate on content strategy, trends, and how to make our messaging more impactful. It feels like working with a true partner.
We teamed up with SeriesX Marketing to look into new markets, but found their talent in revamping our old content was the true win. They breathed new life into nine of our US case studies, thanks to a writer skilled in both SaaS and dental fields, which made all the difference.
Working with the SeriesX Marketing team was a fantastic experience for us. They were proactive, well-organized, and ensured timely delivery of everything. We’re really happy with how the new website turned out. The positive feedback we’ve received so far has been encouraging and is already contributing to our client acquisition efforts. We’d be happy to collaborate with them again in the future.
Exceptional team to work with! The SeriesX team created the first Product Marketing and Content Strategy for ZORP. They were exceptional in translating the founder's vision to actionable plans that helped us execute marketing fast.
SeriesX Marketing puts tremendous effort into understanding our unique requirements and their expertise has significantly improved our online presence. I highly recommend Tara for anyone looking to enhance their SEO & content strategy.

Co-Founder, Managing Partner
Tara Sundaram
Tara spent 15 years on the buying side of B2B marketing — running client-facing demand gen, content marketing & SEO programs for fast growing companies, and hiring and firing content agencies that couldn’t keep up. She co-founded SeriesX to build what she’d been trying to hire.
She leads client strategy, owns the quality bar on every engagement, and is the senior marketing practitioner you’ll work with directly.
Location: Bengaluru, India
Cofounder, Managing Partner
Fatema Karkhanawala
Fatema runs the business behind the agency. Operations, finance, accounting, payroll, internal hiring, contracts, and compliance — all of it is hers. She owns budgets and forecasts, keeps contracts clean, ensures the team gets paid on time, and handles compliance before it becomes a fire-drill.
SeriesX runs as a limited company because Fatema runs the back office like one.
Location: Virginia, USA
Digital Marketing MANAGER
Divya Ramesh
Divya is the operational backbone of client delivery and the agency’s marketing. She runs briefing, on-page SEO, internal linking, graphic designs and repurposing — from LinkedIn snippets to infographics — and manages our writers and designers on infographics, decks, and visual assets.
She keeps the pipeline moving and the details tight on every asset that ships.

delivery team
Writers and designers
Our handpicked team brings 25+ years of combined B2B content experience across IT services, SaaS, HealthTech, MarTech, FinTech, and more. Every draft goes through on-page SEO/AEO optimization and a two-layer edit — a line edit plus a senior marketing review — before it ships.
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.
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.
The work, in detail.
Every engagement is different. These show what’s possible when the brief is right and the work is done properly.
who we serve
Built for B2B marketing leaders running lean teams.
We work best with B2B SaaS marketing teams (Series A–C stage) and IT/professional services firms scaling past 100 people — where content quality and consistency are a constant resourcing problem.
Common fits:
- Heads of marketing and content leads running teams of 1 to 3 people, with a content backlog, U.S./Canada/Europe buyer focus, and a need for weekly conversion-ready assets.
- Marketing leads who’ve tried freelancers or a previous agency, and ended up doing more managing than they signed up for — and now want a content function that runs.
what we do
What we run for you
- Content Strategy — Positioning and ICP clarity, competitive research, content planning, editorial calendar, and writer-ready briefs. Led by a senior marketer who understands your world and goals.
- Content Creation — blogs, landing pages, case studies, eBooks, social, and thought leadership. Optional design services for infographics, one-pagers, decks, and visual assets — built in the same workflow as the copy.
- Content Optimization — on-page SEO/AEO, internal linking, repurposing and refreshing opportunities, and a monthly performance report to scale winners and learn from, so what you publish keeps earning brand equity and customer trust long after it ships.
how we work
Simple, fast, accountable.
- Strategy and briefs — done by us, approved by you: We learn your ICP, study your category, and produce writer-ready briefs. You don’t write the brief, you only check & approve it.
- Create & Design: Senior marketers oversee specialist writers and designers. Two rounds of editing on every asset before it ships.
- Publish & Optimize: On-page SEO/AEO, internal linking, and monthly performance reporting that lets us scale winners and learn what to improve.
what makes us different
Why marketing heads pick SeriesX Marketing
