It finally happened. ChatGPT is now an ad platform.
On March 2nd, Criteo became the first major programmatic ad-tech platform to integrate with OpenAI's ChatGPT advertising pilot. Roughly 17,000 advertisers gained access overnight — at a $60 CPM that makes LinkedIn ads look cheap.
OpenAI's COO framed it as an "ongoing process" rather than a finished product. Translation: they're figuring it out as they go, and early adopters get to shape the playbook.
Here's our take on what this means for SaaS startups.
Why this matters
It's a new intent channel. When someone asks ChatGPT "what's the best project management tool for remote teams?", that's high-intent discovery. Showing up in that conversation with a relevant ad is fundamentally different from interrupting someone's social media scroll.
It's where your buyers already are. AI assistants are the default research tool for 67% of technical buyers. ChatGPT has hundreds of millions of users. The audience isn't theoretical — they're already there, asking questions about your product category.
First-mover advantage is real. The early days of any ad platform — Google Ads in 2003, Facebook Ads in 2012, LinkedIn Ads in 2015 — reward early testers with lower costs and higher returns. By the time best practices are published, the arbitrage window has closed.
The $60 CPM question
Let's be honest: $60 CPM is expensive. For context:
- Google Search Ads: $20-50 CPM
- LinkedIn Ads: $30-80 CPM
- Facebook/Instagram: $5-15 CPM
But CPM doesn't tell the full story. What matters is cost per qualified lead. If ChatGPT users are in active research mode and your ad reaches them at the exact moment of intent, the conversion rate could justify the premium.
Our recommendation: Don't bet big yet. Allocate 5-10% of your paid media budget to test. Run it for 60 days. Measure cost per demo, not cost per impression.
How to approach ChatGPT ads
1. Lead with value, not pitch
Users are in a conversational context. They're asking questions, learning, exploring. A hard-sell ad will feel jarring. Instead, lead with insights, data, or a genuinely useful resource.
Bad: "Try Acme CRM — the #1 rated solution!"
Better: "How high-growth startups are cutting sales cycles by 40% — free playbook"
2. Match the conversational intent
Your ad creative should feel relevant to the types of questions being asked. Think about what your ICP is asking ChatGPT and create ads that feel like natural extensions of that conversation.
3. Build landing pages for AI-referred traffic
Users coming from ChatGPT ads have a different mindset than users coming from Google. They've been in a conversation. They expect depth, not a generic landing page. Create dedicated pages that continue the conversational flow.
4. Track obsessively
This is a brand-new channel with no benchmarks. You're writing the playbook. Track everything: impressions, clicks, time on page, demo bookings, pipeline generated. Build your own benchmarks from day one.
What we're telling our clients
For most early-stage SaaS companies, ChatGPT ads are a test-and-learn opportunity, not a primary channel. Here's our framework:
- Pre-seed to Seed: Skip it. Your budget is better spent on organic content and founder-led outreach.
- Series A: Allocate a small test budget. Focus on bottom-of-funnel queries your ICP is likely asking.
- Series B+: Run a structured 90-day pilot. You have the budget to learn and the data infrastructure to measure properly.
The bigger shift
ChatGPT ads are just the beginning. Google is exploring ads in Gemini. Meta integrated Manus AI into Ads Manager. The entire advertising ecosystem is being rebuilt around conversational AI.
The companies that learn to advertise in AI-first environments now will have a massive advantage over those that wait for the playbook to be written.
