Bandwidth vs Heymarket: at a glance
What is Bandwidth?
Bandwidth adds branded calling — the first move beyond closing self-service gaps.
Most of Bandwidth's recent changelog reads as friction removal: Voice API debug logs surfaced in Voice Insights so customers stop opening tickets, self-service FOC date changes on port-in orders, MOS scores in the app, a longer delivery-receipt window. Identity Presentation breaks that pattern — it is a new product surface rather than a gap closed, putting brand name, logo and call reason on the recipient's handset with a pre-call authentication API to stop the display being spoofed.
What is Heymarket?
Heymarket's feed has gone all-in on SEO explainers, with product news nowhere in the recent window.
The last several weeks are definitional content: what conversational AI is, RCS versus SMS, what a shared inbox does. The most recent real product post in view is Escalations, and before that an RCS campaign walkthrough built on Twilio. Business messaging, a shared team inbox, and AI agents remain the three pillars the content keeps circling.
Bandwidth vs Heymarket: editorial side-by-side
Bandwidth
6.3COMMS
Bandwidth adds branded calling — the first move beyond closing self-service gaps.
◆ Current state
Most of Bandwidth's recent changelog reads as friction removal: Voice API debug logs surfaced in Voice Insights so customers stop opening tickets, self-service FOC date changes on port-in orders, MOS scores in the app, a longer delivery-receipt window. Identity Presentation breaks that pattern — it is a new product surface rather than a gap closed, putting brand name, logo and call reason on the recipient's handset with a pre-call authentication API to stop the display being spoofed.
◆ Where it's heading
Two tracks. Coverage keeps expanding country by country toward full PSTN replacement — Brazil, Mexico and South Korea landed together — which is the wholesale carrier business growing its footprint. The newer track is moving up the stack into call identity and trust, where the product is not minutes but whether the call gets answered. Identity Presentation arriving as a beta built on third-party providers suggests Bandwidth is assembling that layer rather than building it outright.
◆ Prediction
Expect Identity Presentation to move from beta to general availability with a defined pricing model, and the Identity Authentication API to be positioned alongside it as the anti-spoofing control. Country coverage announcements should continue on their steady cadence.
Heymarket
5.0COMMS
Heymarket's feed has gone all-in on SEO explainers, with product news nowhere in the recent window.
◆ Current state
The last several weeks are definitional content: what conversational AI is, RCS versus SMS, what a shared inbox does. The most recent real product post in view is Escalations, and before that an RCS campaign walkthrough built on Twilio. Business messaging, a shared team inbox, and AI agents remain the three pillars the content keeps circling.
◆ Where it's heading
The publishing mix has shifted away from release notes toward top-of-funnel search content, which makes the feed a poor proxy for shipping velocity. What product signal exists points at AI agents handling routine customer messaging and RCS as the richer channel Heymarket is betting on over plain SMS.
◆ Prediction
The repeated RCS and conversational-AI framing suggests the next real release lands in one of those two areas, but the current entries do not support a more specific call.
