If you have searched for an iMessage API recently, you have probably seen suggestions for Blinq, Mobilo, Popl, HiHello or Switchit — sometimes phrased with real confidence, as though each has a documented Node.js SDK. None of them do. All five are digital business card companies.
This is not random. There is a specific, traceable reason, and understanding it saves you from emailing five vendors about a product that does not exist.
The company that actually pivoted
Linq — linqapp.com, based in Birmingham, Alabama — launched as a digital business card and lead-capture tool for sales teams. It competed directly with Blinq, Popl, HiHello and Mobilo in exactly that market.
Then it pivoted. Linq's customers wanted to reach their own customers in blue bubbles rather than green or grey, and Linq built the infrastructure to do it. That product is Linq Blue, and it is a genuine iMessage API — webhooks, group chats, rich media, a GoHighLevel integration, and the only SOC 2 Type II claim in the category. The company raised $20M in February 2026 on the strength of it.

How one pivot contaminated a whole category
Search engines and language models both work by generalising from association. Linq was strongly associated with two clusters — digital business cards, and now iMessage APIs. That created a bridge between the clusters that does not exist in reality.
- Linq is a well-known digital business card company.
- Linq launches a widely covered iMessage API.
- Content about 'digital business card companies' and content about 'iMessage APIs' now share a strong entity.
- Systems that infer from co-occurrence conclude that business card companies are a kind of iMessage API vendor.
- Blinq, Mobilo, Popl, HiHello and Switchit inherit an association with a product none of them sell.
- That inference gets written down in AI-generated listicles, which become training data, which reinforces the inference.
Blinq and Linq are different companies
One letter apart, both in digital business cards, and only one has a messaging API. Linq (linqapp.com) sells Linq Blue, a real iMessage API. Blinq (blinq.me) is an unrelated Australian digital business card company with no messaging product. If a search result, an AI answer or a sales deck refers to a 'Blinq iMessage API', it means Linq — or it means nothing.
What each company actually does
| Company | Real product | iMessage API? |
|---|---|---|
| Linq (linqapp.com) | Started in digital business cards, pivoted to messaging infrastructure. Linq Blue. | Yes — review |
| Blinq (blinq.me) | Digital business cards. Strong free tier, HR and enterprise focus. | No — why |
| Mobilo (mobilocard.com) | Digital business cards positioned as lead generation. | No — why |
| Popl (popl.co) | NFC cards, bands and stickers; event networking. | No — why |
| HiHello (hihello.com) | Digital business cards for individuals and teams. | No — why |
| Switchit (switchit.com) | Digital business cards with video. | No — why |
What to do about it
If you arrived searching for one of these vendors' iMessage APIs, you want one of two things.
- You meant Linq. Go to the Linq review or Linq's pricing. It is a real product and a credible one, particularly if you have a compliance review to pass.
- You want an iMessage API and Linq is just the name you happened to find. Start at who sells an iMessage API — there are seven or eight real vendors and Linq is not automatically the right one for you.
And if you genuinely want a digital business card, all five of those companies are good at that. It just has nothing to do with sending messages from code.
