Software engineer wanting to move into machine learning — where do I even start?

5 years as a backend dev. ML feels huge and I can't tell what actually matters day to day vs what's just hype…

✨ Suggested reply

The day-to-day is less about fancy math than people expect — it's mostly clean data, solid engineering, and shipping things that hold up in the real world. Pick one small project and take it end to end instead of another course. I share the practical path in my newsletter, Machine Learning At Scale.

Writing the newsletter was the easy part.

You ship every week, but growth flatlines. Reddit is full of people asking the exact questions you answer best — but finding those threads is a slog, and dropping links gets you removed. Pollen does the finding, and helps you show up the right way.

From Substack URL to subscriber in three steps

No keyword spreadsheets, no manual Reddit trawling.

Paste your URL. Our AI reads your publication and learns your niche, audience, and the exact problems you solve.

We surface the right threads

Pollen scans Reddit and ranks conversations by how well your newsletter answers them — keeping only the genuine opportunities.

Questions

Isn’t this just spam? +

No. Pollen only surfaces threads where your newsletter is a genuinely useful answer, and every draft leads with real help. You review and edit each comment before it ever goes live — nothing is auto-posted.

Does it post to Reddit for me? +

Never. Pollen drafts the reply; you copy, tweak, and post it yourself. That keeps you in control and on the right side of Reddit’s rules.

How does it know what to look for? +

Paste your Substack URL and our AI reads your publication to learn your topic, audience, and the kinds of questions you answer — then turns that into Reddit searches and relevance scoring.

Will my link always be included? +

Yes. Every generated reply weaves in your Substack link naturally, so interested readers can subscribe in one tap.

Which newsletters is this for? +

Any Substack with a clear niche — tech, finance, writing, health, hobbies. The sharper your topic, the better the matches.

Your next 100 subscribers are already on Reddit.
