The core crew behind the current
Zen Onden
Zen Onden
Zen builds search strategies that behave like revenue systems. With a decade of experience across agencies, in-house teams, and consulting roles, he’s led campaigns spanning SEO, copy, paid media, content, and brand strategy.
Diluvian started after watching one too many brands get burned by bad SEO. The goal was simple: compete on reliability and real results. When Zen isn’t trying to fix SEO, he’s usually trying to balance curiosity with routine.
Vidya Madhu
Vidya Madhu
Vidya builds search systems that don’t collapse under pressure. With over 8 years of experience across industries, she blends technical SEO with AI-driven insights to make search reliable, measurable, and tied to real outcomes.
At Diluvian, she ensures the engine actually runs as well as the strategy promises. When she’s not tangled in the SEO web, Vidya’s either sewing, crafting, or trying to set a great example for her child.
Nagwa Kureshi
Nagwa Kureshi
Nagwa turns language into leverage. With over 12 years of experience spanning publishing, journalism, marketing, and hospitality, she understands how stories influence decisions long before conversions occur.
At Diluvian, she leads narrative and content strategy, making sure every word aligns with buyer psychology, brand truth, and search intent. When she’s not shaping narratives, Nagwa’s probably hiking or watching the sea do its thing.

This was our first time with diving into proper marketing, but Diluvian made SEO feel strategic and simple.
In just 4 months, we ranked for competitive accounting keywords in Delhi. Their work speaks through the ranking they bring.

Zen and his team have been very helpful and professional, especially considering that I have no experience with SEO.
They worked with minimal input from me in terms of creating content and assets. I highly recommend them to anyone looking to work with SEO.

They fixed the Google listing, cleaned up the address confusion, and within six months, the number of calls to our store went up by more than 200%.
No big promises, no jargon, just solid work and they helped us trust SEO again

Frequently Asked Questions
Who is behind Diluvian? What’s your background and experience?
Diluvian is led by Zen Onden and a crew of ex-agency escapees who got tired of how marketing was being done.
Zen has spent years managing full-funnel campaigns in SEO, ads, social, email, brand, and conversion copy for agencies, in-house teams, and consulting clients. After watching one too many “industry-leading” agencies doing the bare minimum, he is building a team that actually cares about outcomes. Wild concept, we know.
What makes Diluvian different from other SEO or digital marketing agencies?
We operate like an un-agency! Meaning, we don’t rely on generic playbooks; we use interdisciplinary thinking (SEO + psychology + positioning + growth) to create strategies that are contextual, story-driven, and ROI-focused. No fluff, no vanity metrics, just outcomes.
What’s your philosophy/approach toward SEO and content marketing?
We treat SEO as a strategic growth engine, not a checklist. Our approach blends narrative, psychology, and technical optimization to create content that ranks, resonates, and drives real business outcomes
How do you ensure transparency and communication during the engagement?
You get full visibility into dashboards, deliverables, timelines, and performance metrics. We maintain structured check-ins, clear documentation, and open channels so you always know what’s happening and why.
If we already have an in-house marketing team, how can Diluvian add value?
A: We act as the strategic and technical layer your team may not have, offering SEO expertise, content systems, audits, and frameworks that make your in-house execution faster, sharper, and more effective.
