Hermes
Hyper-personalize every message sent to user
Every email tool — Loops, Customer.io, Braze — needs setup: instrument events, build segments, write templates. Weeks of setup. Everyone still gets the same email. Hermes uses data you already have. Connect your Postgres (read-only, no schema changes), and Hermes generates a unique email for every user based on real behavior — exactly when it matters. No segments. No templates. No setup. Your data already knows who’s about to churn. Hermes turns that into insight and acts on it.
Hey Product Hunt! 👋
Users don’t churn randomly, they leave with signals sitting in your database.
We saw it happen over and over while building our own SaaS products: a user activates, does something meaningful… then disappears. The “why” was always in the data, we just weren’t acting on it.
So we tried something simple: manually writing a personal email to each user based on what they actually did.
It worked. Every time.
It just didn’t scale.
So we built Hermes.
Here’s the difference:
Loops, Customer.io, Braze → Require heavy setup. You push data in, define segments, send the same template to everyone.
Monaco → Helps you win new customers.
Hermes → Connect your Postgres (read-only), and instantly send a unique, behavior-aware email to every single user — at the exact moment it matters.
No segments. No templates. Just messages that actually understand the user.
We launched a week ago:
→ 7 B2B customers
→ zero outbound
→ zero churn
And the biggest signal so far: founders are already referring other founders to us — including YC teams — which has been our only growth channel.
If you’ve ever watched users disappear and wished you could act on it instantly, we built this for you.
We’re onboarding new teams this week for free — would love your feedback 🙏
