Building SaaS from zero to real users — in public.
Most startup advice skips the messy middle. I write about the part between "I built something" and "people actually use it."
I'm currently building ZeroToUser and SpotAQ, and documenting what I learn about early distribution, product adoption, AI visibility, and founder consistency.
What I Write About
- User intent
Finding real user intent before building more features.
- Signal from conversations
Turning messy conversations into product and GTM signal.
- Low-feedback building
Building through low-feedback periods.
- Product adoption
Reducing product adoption friction.
- AI visibility
Making SaaS brands visible in the AI/LLM era.

From 0/30 to 15/15: What Dogfooding Taught Me About AI Lead Quality
How dogfooding ZeroToUser helped me improve its first reviewed batch from 0/30 relevant leads to 15/15—and what I learned about AI lead qualification.
I Used ZeroToUser to Find Users for ZeroToUser—and Found a Problem
I used ZeroToUser to find potential users for ZeroToUser. The results exposed a deeper product problem: the system was filling the daily lead quota before proving that each conversation was actually relevant.
AI Visibility Is Not Just for SaaS
AI visibility is not only a SaaS problem. As AI becomes a discovery layer, ecommerce brands, agencies, exporters, local businesses, and service companies will all need to understand how AI systems describe, compare, cite, and recommend them.
Customer Intent Does Not Live on One Platform
ZeroToUser should not be built around one platform. Customer intent is scattered across X, Reddit, Facebook, LinkedIn, TikTok, reviews, directories, search, and AI answers. The real product is a customer-intent signal engine.
