The secretary you need to get organized but can't afford.
Slim is your office manager — available by phone or text, 24 hours a day. Tell him what you need. Consider it done.
No credit card. No software to learn. Just call.
Every busy field professional knows exactly what it feels like to be disorganized. Missed calls. Lost notes. Forgotten follow-ups. Quotes that never went out.
Whether you use a CRM or run everything from memory — Slim fills the gap between what you mean to do and what actually gets done.
Not software. Not a dashboard. A person who works for you.
How Slim works
Call or text Slim
Tell him anything. A new customer, a job update, an appointment, a follow-up you need. Slim listens, asks you questions, and remembers.

Two minutes. What happened yesterday, what needs attention today. That's it.

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.
Built by people who get it
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.
