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.
What is Subsplash?
Subsplash's Workflows feature goes GA with email automation on every step, unifying church operations in one platform.
Subsplash is systematically converting its Workflows feature from beta to a full operational backbone for church teams: email automations trigger on card movement, a 'My Cards' view surfaces all assigned work across every workflow, completion notifications go to team leaders automatically, and the rebuilt Transfers & Reconciliation page handles bank deposit matching with audit trails. The AI People Assistant (natural language filtering) and Trends AI (media + campaign data) are building toward a data-informed operations layer.

Bandwidth
6.3COMMS
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.
Subsplash
2.5COMMS
Subsplash's Workflows feature goes GA with email automation on every step, unifying church operations in one platform.
◆ Current state
Subsplash is systematically converting its Workflows feature from beta to a full operational backbone for church teams: email automations trigger on card movement, a 'My Cards' view surfaces all assigned work across every workflow, completion notifications go to team leaders automatically, and the rebuilt Transfers & Reconciliation page handles bank deposit matching with audit trails. The AI People Assistant (natural language filtering) and Trends AI (media + campaign data) are building toward a data-informed operations layer.
◆ Where it's heading
Subsplash is moving toward unifying giving, event management, people management, and operational workflows into a single platform for churches — reducing dependence on external tools like SurveyMonkey for surveys or separate streaming platforms. The 'My Cards' view and email automation completion notifications are the kinds of features that shift Workflow from a nice-to-have into a primary daily interface for church staff.
◆ Prediction
Automations will gain conditional branching and third-party integrations (email providers, SMS), and Trends AI will expand to include workflow completion and giving pattern correlations — moving toward a full church operations intelligence layer.
