ZeroSettle

Overview

ZeroSettle gives a business its own phone number on iMessage, running on Apple hardware ZeroSettle operates in a server facility. Your code sends through a bearer-token REST API and receives replies on signed webhooks, or a hosted AI agent (in Beta) answers for you. The same company also runs a mobile billing product, and its homepage says it is backed by Y Combinator.

How it compares to Linq

Both sell managed iMessage numbers at a flat monthly price with no per-message fees. ZeroSettle is iMessage only, while Linq falls back from iMessage to RCS to SMS. Linq has a free Hobby tier and Pro from $260/month; ZeroSettle starts at $49/month with no free tier. Linq offers SDKs, a CLI, read receipts and iMessage apps; ZeroSettle's docs say it has no SDK and no read or delivered events. Linq states SOC 2 Type II and contractual SLAs on Enterprise; ZeroSettle publishes no SLA.

Best for

Teams that mostly talk to iPhone users who text first, such as support lines, sign-in flows and opted-in follow-ups, and that want a low-cost number with a simple API or a no-code AI agent.
