I recently watched a fascinating Marketing Against the Grain video that completely shifted my perspective on how AI is transforming marketing. While many of us are worried about Google search traffic disappearing and AI disrupting traditional channels, Kieran Flanagan presented something far more exciting: a new marketing playbook centered around “micro audiences.”
This approach isn’t just theoretical—it’s a practical strategy that could generate significant revenue by leveraging AI tools like Perplexity Labs to target highly specific segments of your audience with personalized marketing.
Why Micro Audiences Matter
Traditional marketing has always focused on broad Ideal Customer Profiles (ICPs). We create content and ads for these broad audiences because we need enough scale to justify hiring marketers to reach them.
AI changes this equation completely. Instead of marketing to broad segments, we can now identify and target micro-segments of our audience with highly personalized messaging—without needing to hire an army of marketers.
Think about it: What if you could create 100 different marketing campaigns for 100 different micro-segments of your audience, each addressing their specific pain points and KPIs? That’s the power of this approach.
How to Build Your Micro Audience Strategy
The process Flanagan outlined involves three key steps:
- Create your Ideal Customer Profile (ICP) using AI tools like Claude
- Use Perplexity Labs to identify micro audiences within your ICP
- Generate tailored marketing campaigns for each micro audience
What impressed me most was how Perplexity Labs can chain multiple tasks together. For example, it can parse your ICP document, extract KPIs, search LinkedIn job ads for companies hiring roles that match your buyer personas, and then cluster these companies based on the metrics they’re prioritizing.
Finding Hidden Opportunities
One of the most powerful aspects of this approach is discovering new KPIs your potential customers care about that you might not be addressing in your current marketing.
For instance, Flanagan showed how HubSpot could identify companies seeking “pipeline velocity optimizers” or “conversion rate maximizers” by analyzing job postings. These companies are explicitly stating what metrics matter to them—giving you a clear path to position your product as the solution.
“Instead of having AI replace the human and create the video asset for me, I can have human plus AI create 100 videos for 100 micro audiences versus how it works today, create one video for a broad ICP.”
The beauty of this approach is its scalability. You can adjust parameters like how far back to look for job postings (45 days, 90 days, etc.) to expand your micro audience clusters. You can also create different types of “hunts” beyond job postings—like finding companies with complementary tech stacks that signal they need your solution.
Putting It Into Practice
Once you’ve identified your micro audiences, you can use AI to generate tailored marketing assets for each one:
- LinkedIn carousel ads addressing their specific pain points
- Email sequences that speak directly to their unique challenges
- Landing page wireframes for micro-sites targeting each segment
- Video scripts that demonstrate how your product solves their specific problems
While the AI-generated assets might need refinement, they provide an excellent starting point that’s far more targeted than generic marketing materials.
My Take: This Changes Everything
Having worked with businesses of all sizes on their marketing strategies, I can tell you this approach has game-changing potential. The ability to create highly personalized marketing at scale without proportionally increasing your marketing team is revolutionary.
What excites me most is how this strategy combines the best of both worlds: the precision of account-based marketing with the scale of broader campaigns. It’s not about replacing humans with AI—it’s about using AI to make human marketers exponentially more effective.
I recommend starting small with this approach. Pick one segment of your ICP, use these tools to identify 2-3 micro audiences within it, and create tailored campaigns for each. Test the results against your standard marketing approaches, and I suspect you’ll see significantly higher engagement and conversion rates.
The future of marketing isn’t about broader reach—it’s about deeper relevance. And AI is making that possible at a scale we’ve never seen before.
