I wrote a 550 page platform engineering book and launched it 8 weeks ago. Here is what actually happened.
On 25th April 2026 I published The Comprehensive Guide to Platform Engineering, a 550 page practical reference for senior engineers and platform leads. Priced at £49.99 for a single licence, £179 for a teams licence.
Eight weeks in: 6 sales, £299.94 revenue.
Not a rocket ship. But I am building in public so here is the honest breakdown.
What I did
LinkedIn four times a week on my personal profile, long form structured argument posts in my content lane of platform engineering in regulated financial services. Also running a company page for the book brand at a similar cadence. No paid promotion.
Three articles on Dev.to covering platform engineering topics with natural book mentions at the end.
Reddit across r/devops, r/platformengineering, r/kubernetes, and r/observability. Genuine technical comments on relevant threads, posts in weekly self promotion threads only.
Product Hunt launch earlier this month.
Platform Engineering Slack community, posted in intro, books, and promotions channels.
What actually worked
LinkedIn has driven consistent engagement and significantly expanded my network. The honest caveat is that most of the inbound is recruiters and vendors rather than buyers. The content is landing with the right audience technically, the conversion to sales is slow.
The Platform Engineering Slack community drove at least one confirmed sale through genuine discussion rather than promotion. That pattern, real conversation leading to trust leading to a purchase, feels like the most authentic conversion path.
Reddit is valuable for credibility building and technical discussion but the conversations are time consuming and do not convert directly. Playing the long game there.
What has not worked yet
Product Hunt came and went without meaningful sales impact.
Dev.to drives almost no organic traffic on its own without external promotion pushing people there.
Testimonial outreach to buyers is pending, no responses yet.
Hacker News Show HN post is still in the queue.
What I am figuring out
The audience finds me. The conversion to purchase is the gap. Six people have paid which means the product has value for someone. The question is how to reach more of the right people efficiently without a marketing budget.
If you have launched a technical book or niche information product I would genuinely value hearing what moved the needle for you.
What caught my attention wasn't the six sales.
It was "the audience finds me, the conversion is the gap."
Those two observations can feel highly compatible while still leading to very different conclusions about what's actually happening.
That's usually where things start getting interesting.
You are right that they can point in very different directions. My current read is that the content is reaching the right people but the path from awareness to purchase is too long or too friction-heavy. Though I am open to the possibility that I am wrong about who the right people actually are. What conclusions are you drawing from it?
I'm not sure I'd want to compress that into a thread reply.
The reason I commented in the first place is that I think there are a few different conclusions that could reasonably fit the same facts, and they don't all point in the same direction.
If you'd like my thoughts, drop your email and I'll send you a note.
