Your PPC management costs are $15K/month.

Your PPC management costs are $15K/month. Your agency charges 15% of spend. You're paying $225K annually for work you could automate. A VP of Digital at a $180M brand told me: *"We've outgrown three agencies. None of them understand our business. But building in-house feels impossible."* I built my own PPC SaaS. Generated $120K ARR. It wasn't because I wanted to be in the software business. It was because existing solutions didn't solve my problem. When I was managing a $45M PPC budget, I spent 40 hours a week on tasks that should have been automated. Bid adjustments, budget pacing, anomaly detection, creative fatigue monitoring. I built a system that did it all. Cut my management time by 80%. ROAS lifted 19%. **The Build-Your-Stack Framework:** 1. Identify repetitive tasks. If you do it more than once a week, automate it.n2. Start with scripts, not software. Python scripts solved 80% of my PPC problems.n3. Build incrementally. One feature at a time, validated by actual need.n4. Open-source your infrastructure. Don't reinvent the wheel.n5. Sell what works. My $120K ARR PPC SaaS started as internal tooling. The brands winning in 2026 aren't dependent on agencies or vendors. They're building their own competitive advantages. I've cut CPA by 66%, tripled ARR, and led 31-person global teams. But my greatest advantage? The tools I built that no competitor has. What's your most repetitive PPC task? Why haven't you automated it yet?
