What's actually working in SaaS growth, straight from the field.
Founder Field Notes is a weekly newsletter for SaaS founders. Real tactics, teardowns, and numbers pulled from the acquisition campaigns we run every week.




Dear founder,
You do not need another newsletter telling you to 10x your pipeline with AI, or a thread from someone who has never spent a real ad budget.
You need to know what is actually moving the needle in SaaS acquisition right now. The ad angle that just dropped a client's cost per demo. The landing page change that lifted trial signups. The funnel structure that finally made paid profitable.
Every week we send what we shipped, what worked, what did not, and what we would do differently if we ran it again. It comes straight from live campaigns, with the real numbers attached.
If that sounds more useful than another hot take, drop your email above.
Filed from the field,
Michael, Fitr Media
Each issue is a short, high-signal read. In any given week you might get:
- The ad angle or creative that cut a client's CAC, and why it worked
- A landing page teardown, with the one change that moved conversion
- Real numbers from live SaaS funnels: CPC, cost per demo, trial-to-paid
- A distribution play that is compounding right now, before everyone copies it
- The mistake that cost us (or a client) money, so it does not cost you
Founder Field Notes is written by the team at Fitr Media, where we build full-funnel user acquisition systems for SaaS companies. These notes are not researched from the outside. They are the byproduct of the work.
- $60M+ in client pipeline generated
- 250% peak conversion rate lift
- 71% average CAC decrease
Trusted by teams at Workday, Elevate, and AdConversion.
Read this if you are: a SaaS founder or growth lead past $1M ARR, trying to turn ad spend into predictable, paying users.
Skip it if you want: generic marketing theory, growth-hack threads, or a course from someone who has never scaled a SaaS.
