The Problem
A 10-client agency pays $500-$1,000 per client monthly. That's money leaving your business forever.
Your client lists live on someone else's servers. One policy change and you're locked out.
No white-labeling. No customization. You're reselling the same platform as everyone else.
There's a different path.
See how ownership changes everythingThe Solution
One payment. Forever yours.
Replace $60-120K/year in SaaS fees with a single $20K investment. Scale from 10 to 50+ clients without adding platform costs.
Your server. Your rules.
Self-host on AWS, DigitalOcean, or any cloud. Route through any ESP. No account suspensions. No platform dependency.
Your brand. Not theirs.
Full white-labeling with your logo, domain, and custom features. Position as a tech company, not a reseller.

Insights
Octeth v5.9.5 ships today, our second release on the two-week cadence and our second in a row with no new features. It closes the last vulnerability from the audit that produced the v5.9.4 fixes, and it repairs a report that had been showing an empty result to every customer who used it since the day it shipped. Nobody reported that one, and I think the reason why is worth talking about.
Octeth v5.9.4 ships today with zero new features. It closes two vulnerabilities we found auditing our own code, and fixes a segment rule bug that could quietly sweep suppressed contacts into an audience. It's also the first release on our new two-week cadence — and a small, unglamorous release is exactly what that cadence is supposed to produce.
