On the road? Meeting clients all day? At a job site? Every busy field professional knows they optimize their time when they are organized. Missed calls. Lost notes. Forgotten follow-ups. Quotes that never went out.

Not software. Not a dashboard. A person who works for you.
How Slim works
Call or text Slim anytime
Tell him anything. A new customer, a job update, an appointment, a follow-up you need. Slim listens, asks you questions, and remembers.
Slim handles it
Proposals go out, reminder calls get made, follow-ups get scheduled. All in the background while you're working.
Slim calls you every morning
Two minutes. What happened yesterday, what needs attention today. That's it.
No software to learn. No app to open. Just call Slim.
Talk to Slim and he...
Never forgets. Never sleeps. Always picks up.
Built for people in the field
If you make your money on the road, on a job site, or with a handshake — Slim was built for you.
You are busy. Your time is too valuable.
You lose real money when things fall through the cracks.
Whether you use a CRM, paper, or run everything from memory — Slim fills the gap.
The story behind CallSlim
Pax is 18. He skipped college to build a business — his dad Scott suggested they do it together, and CallSlim was born. We are not a software company. We are two people who believe that busy professionals in the field deserve something simple that actually works the way they do.
CRM software is great — if you are at a desk. But when you are closing deals out of your car or fixing a pipe under a sink, you need speed and simplicity. You need someone who just handles it. That is why we built Slim.
When you call Slim, you are not calling a product. You are calling something we built because we believed it should exist.
We are here for you. Thanks for trying out Slim.
— Pax & Dad
