What is Subsplash?
Subsplash is wiring automation and AI through the church admin stack it already owned
Workflows came out of beta in mid-July with per-step email automation, then immediately gained completion notifications for team leaders. Around it, the administrative surfaces are being rebuilt in sequence: Transfers and reconciliation now tracks who reconciled what and when, Groups gained member limits with a Full badge and finder filters, and event managers can register guests and waive payments directly from the dashboard. The AI line is filling in too — Trends AI added media and campaign data on top of giving, people, attendance and groups, following the natural-language People Assistant in May.
What is Bandwidth?
Coverage, quality metrics and self-service — Bandwidth is closing the gaps enterprises audit it on.
Bandwidth spent the quarter filling in the boxes an enterprise buyer checks before consolidating carriers. Brazil and Mexico reached full PSTN replacement with national outbound calling and emergency services, South Korea gained emergency services, MOS scores landed in the app for perceived call quality, and 10DLC registration moved into a Registration Center with API access. The newest release lets customers change or cancel a port-in FOC date themselves up to ten minutes before the port window.

◆ Current state
Workflows came out of beta in mid-July with per-step email automation, then immediately gained completion notifications for team leaders. Around it, the administrative surfaces are being rebuilt in sequence: Transfers and reconciliation now tracks who reconciled what and when, Groups gained member limits with a Full badge and finder filters, and event managers can register guests and waive payments directly from the dashboard. The AI line is filling in too — Trends AI added media and campaign data on top of giving, people, attendance and groups, following the natural-language People Assistant in May.
◆ Where it's heading
Two threads run in parallel and are starting to meet. One is turning manual church-admin chores into configured automation — workflows that send their own emails, notify on completion, and enforce group capacity without a staff member watching. The other is putting a natural-language layer over an increasingly complete data set, which only becomes useful once giving, attendance, media and campaigns all live in the same place. Recent releases have been closing the gaps in that data set.
◆ Prediction
The obvious convergence is Workflows becoming triggerable from the data — a Trends AI segment or People Assistant query that drops matching people onto a workflow board automatically. Reconciliation gaining an export or accounting-package integration is the other near-term candidate given how much structure was just added to Transfers.
Bandwidth

Coverage, quality metrics and self-service — Bandwidth is closing the gaps enterprises audit it on.
◆ Current state
Bandwidth spent the quarter filling in the boxes an enterprise buyer checks before consolidating carriers. Brazil and Mexico reached full PSTN replacement with national outbound calling and emergency services, South Korea gained emergency services, MOS scores landed in the app for perceived call quality, and 10DLC registration moved into a Registration Center with API access. The newest release lets customers change or cancel a port-in FOC date themselves up to ten minutes before the port window.
◆ Where it's heading
The pattern is replacing support tickets and coverage caveats with self-service and API surface. Number porting, campaign registration and quality monitoring were all previously mediated by Bandwidth staff or opaque to the customer; each is becoming something the customer operates directly. The messaging work follows the same logic — a send confirmation at the carrier network and a delivery receipt window stretched from 12 to 73 hours give customers a truer picture instead of a premature expiry.
◆ Prediction
10DLC Registration Center is explicitly early access and US and Canada only, so the near-term move is general availability and more countries; the more interesting question is whether the BYO-AI call-transfer work sitting just outside this window gets promoted to a first-class capability.
