About Sunny Guha

The marketer who ships the system.

Twelve-plus years turning ad spend into pipeline — managing $400K+ a month across 500+ brands in the US, UK, UAE and Australia, with 22–30x ROAS in healthcare and a Google Ads Partner Certified track record. I'm also a Computer Science engineer — so I direct agentic AI to build the landing pages, CRMs and automation behind the growth. Two disciplines that almost never live in one person.

Peak ROAS (healthcare / IVF)

I started in 2012, freelancing out of India and learning performance marketing the honest way — personally accountable for every rupee and dollar of spend. Across that first decade I promoted 50+ Indian brands in healthcare, education, hospitality, retail and fitness, and built the foundations: ads, landing pages, email and analytics.

From 2021, I went independent and founded OIESU — growing from a solo consultant to an agency principal running six-figure monthly budgets for 150+ international brands across the US, UK, UAE and Australia, with up to 30x ROAS for IVF and fertility clinics and cost-per-lead cut by as much as 40%.

Since February 2024, I've been a Senior Paid Media Specialist at Growth99, owning premium high-budget accounts and escalations as an unofficial small-team lead — the person brought in to rescue underperforming $15k–$30k/mo accounts and restore them to peak.

The part most marketers don't have: I'm a Computer Science engineer (M.Tech, CGPA 8.7). I've shipped 100+ algorithmic trading systems and built an AI marketing-automation platform with 20+ concurrent agents — including a custom CRM with email and WhatsApp automation. So when a growth plan needs a landing page, a tracking layer or an internal tool, I don't brief a backlog. I direct the AI and I build it.

Ex-founder · OIESU

A chapter that reshaped the craft

In 2024, Sunny stepped back from running OIESU — the agency he founded — following the loss of his fiancée, who was also his business partner. He channelled that chapter into deepening his craft: joining Growth99 as a senior paid-media specialist, and building the AI systems that now let one person deliver what used to take a team.
Forward, and building.

The AI-native toolkit

How one person delivers what used to take a team

I don't hand-code line by line. I direct agentic AI to build and ship — and I know the stack well enough to review, debug and steer it to production. This is the leverage behind the output.

AI models

The models I run daily for strategy, copy, analysis and building.

Programming — via AI

I'm not claiming to type every function from scratch. I direct agentic AI to build in these languages and frameworks, and I know each one well enough to steer the architecture, catch the bugs and ship it. This very site is a Next.js build done that way.
