Hey Indie Hackers,I run a small consulting practice deploying AI agents for SMB offices across DACH — engineering firms, planning practices

After 30 client deployments, I noticed every book on the topic was either consulting fluff or ML PhD textbooks. Nothing for a 25-person office that decides on Monday and wants to ship in 30 days.

So I wrote one. 140 pages, two parts (decision-makers + implementers), released two weeks ago.

The numbers so far:

• 8 sales, $321 revenue

• 175 views, 4.6% overall conversion

• 7 of 8 sales from Switzerland (my home market)

• 60% conversion from my own website, only 4% from direct Gumroad links

Three things surprised me:

1. My own domain converts 15× better than Gumroad direct. Trust matters more than I expected. Now I redirect every link through my own domain first.

2. Newsletter list converted at 0%. 22 clicks, 0 purchases. I think I gave too much value in the newsletter itself — readers felt sated, not curious. Testing a shorter, harder-CTA version this week.

3. The book isn't the business — it's the trigger. Real revenue model: $40 book sale → 1 in 8 buyers books a $2k audit → 1 in 3 audits becomes a $12k pilot. The book is the lead magnet; the engagements are the business.

Currently working on:

• Free Part 1 PDF as lead magnet (capture emails)

• 3-email Buyer → Audit conversion sequence

• Public GitHub repo with code examples from the book

Happy to dig into specifics. What would be most useful — the conversion sequence, the audience targeting, or the technical stack behind the agents?
