Phound vs. Signal comparison.
Millions of people trust Signal for one reason: nobody — not Signal, not an advertiser, not a hacker — gets to read what's inside. That reputation is earned. It's also exactly why some small business owners and teams try to run their business on it, too. The privacy habit is a good one. The problem is that a private messenger and a business communications platform are built to solve two different problems, and Signal was only ever built for one of them.
Here's where the two actually diverge, and where teams outgrow Signal fast.
What Signal gets right — and why that's part of the problem
Give credit where it's due. Signal's encryption is independently audited, the protocol is open source, and the whole organization runs as a nonprofit with no ads and no data harvesting. If your goal is a private conversation between two people, Signal remains the gold standard.
That's also the trap. Signal is so good at being a private messenger that it's easy to forget it was never designed to be anything else. There's no business phone number behind it, no way to route a call to the right teammate, and no record of what was discussed once the conversation disappears. The same design choices that make Signal great for privacy make it thin for running a business.
Where teams outgrow Signal
No real business phone number
Signal requires a phone number to sign up, but it doesn't give you a business one, on any tier. Your team is still handing out personal cell numbers, and every new hire means another private number exposed to clients. Phound gives you a dedicated Phound number free on Basic, and a real, callable-from-any-phone business number on Pro and Business, the kind that works whether the person on the other end has the app or not.
Calls stop at the app's edge
Signal calling only works between two Signal users. Call a customer, a vendor, or anyone who hasn't installed the app, and there's nothing to dial — the conversation has to move to a regular phone call on a completely different number. On Pro and Business, Phound calls anyone on any phone, from the same real business number your team already uses.
No AI, no searchable history
Signal's disappearing messages are a privacy feature for individuals. For a business, they're a liability: no call summaries, no searchable record of what a client asked for last month, nothing to hand off when someone's out sick. Phound summarizes every call, transcribes every voicemail, and keeps a searchable history behind every contact, automatically.
No admin controls, no team management
There's no way to add a teammate, remove one, assign a shared number, or see how your team is actually communicating with customers. Signal has no concept of a "team" at all. It's built for individuals, one install at a time. Phound Business gives you a central admin console to manage numbers, routing, and access as your team grows.

Signal recently raised its group call limit to 75 participants, a real improvement for a messaging app. It's still a ceiling built for conversation, not for the kind of all-hands or client meetings Phound's Pro and Business plans handle at up to 500 people.
Which one is right for you?
If what you need is a private line for personal conversations, keep Signal. It does that job better than almost anything else out there, and Phound isn't trying to replace it.
If what you need is a way for clients and customers to reach your business, for your team to share numbers and context, and for AI to handle the busywork of summarizing calls and transcribing voicemails, that's a different job, and it's the one Phound was built for.
