What is Session?

Session pulls back from a funding crisis as community support revives development

Session's recent feed is dominated by survival, not shipping: a cofounder's personal appeal warning the project might not continue, followed by news that community donations, node operation, and awareness restored its runway and development will resume. Underneath sits real roadmap work — Session Protocol V2 (forward secrecy, post-quantum crypto) and the long-running Session Pro Beta.

What is Bandwidth?

Bandwidth ships Identity Presentation (branded calling) in beta — trust layer for enterprise outbound calling.

Bandwidth is an enterprise communications API provider actively shipping across messaging, voice, and number management. The last 30 days include SIP trunking on Build, 10DLC registration in the app UI, RCS test number self-serve, and voice debug logs in Voice Insights. Identity Presentation — authenticated branded calling that displays the caller's brand name, logo, and call reason on mobile phones — entered beta on August 14 and is the most differentiated new capability.

Session pulls back from a funding crisis as community support revives development

◆ Current state

Session's recent feed is dominated by survival, not shipping: a cofounder's personal appeal warning the project might not continue, followed by news that community donations, node operation, and awareness restored its runway and development will resume. Underneath sits real roadmap work — Session Protocol V2 (forward secrecy, post-quantum crypto) and the long-running Session Pro Beta.

◆ Where it's heading

The product spent recent months in existential mode and has now stabilized enough to resume development and keep critical infrastructure running. The technical direction — post-quantum cryptography and forward secrecy in Protocol V2, plus Pro Beta features — remains the substance, but momentum hinges on the donation-funded model that just rescued it.

◆ Prediction

Expect development to resume around Protocol V2 and the Session Pro Beta, with continued reliance on community funding; pace depends on whether the donation rebound holds.

B6.3

Bandwidth ships Identity Presentation (branded calling) in beta — trust layer for enterprise outbound calling.

◆ Current state

Bandwidth is an enterprise communications API provider actively shipping across messaging, voice, and number management. The last 30 days include SIP trunking on Build, 10DLC registration in the app UI, RCS test number self-serve, and voice debug logs in Voice Insights. Identity Presentation — authenticated branded calling that displays the caller's brand name, logo, and call reason on mobile phones — entered beta on August 14 and is the most differentiated new capability.

◆ Where it's heading

The platform is advancing on two simultaneous tracks: developer experience (self-serve tooling replacing support tickets, debug visibility, UI for previously API-only workflows) and differentiated enterprise capabilities (branded calling, RCS agent testing, MOS voice quality monitoring). The Brazil PSTN replacement expansion shows the geographic build-out is ongoing. Each release reduces friction at a specific operator task.

◆ Prediction

Identity Presentation moving from beta to general availability is the most likely near-term announcement. RCS expansion to additional carriers or geographies is the second active investment, given the self-serve test number tooling that just shipped.
