Twelve years
of media buying
behind one agency.
GPT Ads AI was founded by Tarun Kapoor — a performance marketer shaped by the world's largest holding companies, a $6.5M ARR founder-led agency, and the top 1% freelance network in the industry. This is the experience now running your ChatGPT Ads channel.
Tarun Kapoor
Founder & Lead Operator · GPT Ads AI
Tarun has spent twelve years inside the discipline of paid media — first as an enterprise media buyer at the world's largest agency holding companies, then as the operator responsible for the bottom line at one of the most recognized founder-led marketing agencies on the internet.
At Neil Patel Digital — an agency doing roughly $6.5M in annual recurring revenue — Tarun was the senior media buyer responsible for adding more than $3.5M to the bottom line. He led paid acquisition for Ubersuggest, one of the largest independent SEO tools in the world, alongside a roster of global enterprise brands.
Today he advises Fortune 500 marketing teams and venture-backed startups as a fractional CMO — often getting operative on media buying, team builds, and the operating cadence in between. GPT Ads AI is the agency he built to bring that discipline to the first new performance channel of the AI era.

Make AI ads boring.
For two decades, advertising on Google was a wild experiment. Then it became a P&L line. The same compression is happening with ChatGPT Ads — and the brands that get there first will lock in a CAC advantage their competitors spend years trying to undo.
Our job is to make that channel feel as predictable, instrumented, and accountable as any mature performance channel. Less novelty, more compounding spend.
Four principles that
survive a Monday morning.
Revenue or it didn't happen
We report on revenue, contribution margin, and payback — not vanity metrics. If a campaign isn't moving the P&L, we kill it.
Ship weekly, not quarterly
New creative, new audience tests, and account changes land every week. Slow learning is the most expensive thing in paid media.
Operator-grade transparency
You see the account, the dashboard, the creative pipeline, and the loss reasons. No black-box reporting.
AI-native, channel-agnostic
ChatGPT Ads are our edge. Meta, Google, TikTok, and LinkedIn are still where most spend lives. We run both with equal seriousness.
