Every business loses people it could keep.
Someone signs up and never comes back. A cart gets left behind. A customer drifts toward cancelling. Big companies pay a lifecycle team to catch these moments. Most businesses can’t.
Big companies pay a whole team to keep customers. You have an AI.
We built Banger so any business can welcome, follow up with, and win back every customer, with the AI it already uses.
Why we built Banger.
Your AI can be that team.
ChatGPT, Claude, Grok, Hermes, and OpenClaw can already write and reason. Banger gives them what they were missing: real mailboxes, Journeys, Broadcasts, and delivery.
It gets better with every send.
Your AI tests versions, keeps what works, and brings what it learned to the next email.
Two cofounders who’ve spent years building communication products.
Tiago shaped his product and engineering taste at Automattic and Beeper, working on communication products including Beeper and Beeper Mini.
Luiz brings deep engineering and systems judgment from Microsoft and Cadence Design Systems.
How we build for the agentic era.
Agent-first
Everything a person can do in our products, an AI can do too, through the same tools.
Smart
Our products bring the right context to every request, so your AI gets it right the first time.
Results, not busywork
Every feature has to move a real number for the people using it.
Crafted
What your AI makes should look and sound like you, and the product around it should still be a delight to use.
Your data stays yours
We don’t sell it or train models on it, and every agent sees only what you allow.
