Make business phone communication as simple as sending an email.
Every business runs on texts and calls. Almost none of them should have to think about how those messages reach a phone. SignalRoute takes the entire tangle of telecom and hides it behind one engine — a Line app for owners who want it to just work, and a developer API for builders who want full control.
The old way
Reaching a customer should not require a project plan.
For decades, getting a business phone number that could reliably text and call meant wading through a system that defeated non-technical owners and frustrated the engineers building on top of it.
Weeks of paperwork before you can say hello
Registrations, approval queues, and forms that ask for things no one on your team understands. You wait, and you wait, and you're still not sure why.
Messages that vanish without a trace
You hit send, the customer never replies, and there's no way to know your text was silently dropped on the way out the door.
A different vendor for every channel
One service to text, another to call, a third to prove you're a real business. Five logins, five invoices, and nothing that talks to each other.
We thought the whole thing was backwards. The complexity is real, but it is not the customer's problem to solve. So we put it where it belongs — out of sight. You connect a number, write your message, and press send. We handle everything that has to happen for it to land.
What we believe
Principles we don't bend on.
A handful of ideas shape every decision we make — from the product down to the punctuation.
Hide the hard parts
Real complexity sits under the hood — verification, deliverability, routing. Our job is to make sure you never have to learn a word of it.
Fast by default
From signing up to your first sent message should be minutes, not weeks. Every screen is designed to get out of your way.
Earn trust on the line
When you call, your name shows up. When you text, it arrives. We do the unglamorous work so your customers actually pick up.
Premium, not complicated
Powerful does not have to mean cluttered. We sweat the typography, the empty states, and the details you only notice when they're missing.
How we build
A small team obsessed with one thing.
Small and senior
A focused team from product, infrastructure, and deliverability — not a call center.
One engine, two faces
Line for owners who want it to just work, a developer API for builders — same numbers, same AI.
Honest by default
Transparent usage pricing, real logs, and no numbers we can't stand behind.
Built for the next message you send.
Spin up a number, send your first text, and place your first call — all in a few minutes, with no paperwork to decode.
