SIGNALMASH LEADERSHIP

Derek Dempsay

VP of Global Operations, Signalmash

Derek runs global operations, with a background spanning CPaaS, VCaaS, telecommunications, APIs, and messaging. He is the operator behind the white-glove carrier approvals and the delivery infrastructure customers depend on.

What Derek works on

Derek runs the part of RCS that businesses find hardest to do alone: getting a brand verified and approved by carriers and by Google, and keeping messages landing once it has been. A2P messaging is not a single integration but a standing relationship with four US networks, each with its own registration requirements, filtering behaviour, and escalation path. He has worked that ground across CPaaS, VCaaS, APIs, and messaging, which is why SimplyRCS handles approvals for customers rather than handing them a checklist and wishing them luck.

Carrier approvals, handled for you

Brand registration, use-case declaration, and sender verification are done by the operations team on behalf of the customer. This is the step that most often stalls an RCS launch for weeks when a business attempts it unassisted, usually on a detail no one told them mattered.

RCS agent verification with Google

A verified agent is what puts a brand name, logo, and check mark in the thread. Getting there means satisfying Google on brand ownership and on how the agent will actually be used, then keeping the declaration true as the programme grows.

Deliverability across all four US networks

Direct connections to AT&T, Verizon, T-Mobile, and US Cellular only help if traffic is shaped to what each network expects. Watching delivery behaviour per carrier, and reacting when filtering changes, is continuous operational work rather than a launch task.

Coverage that does not sleep

The team behind Signalmash works across several countries specifically so network operations and support are staffed around the clock. Messaging failures do not wait for business hours in Oregon.

Areas of expertise

What Derek can speak to first-hand, and reviews before we publish:

  • Carrier approvals and verification
  • A2P message deliverability
  • CPaaS operations

Education: DeVry University

What Derek reviews

SimplyRCS content is written and reviewed in-house by the same people who run carrier approvals, deliverability, and support, because most of what we publish is operational knowledge rather than research. Derek is the reviewer for carrier approvals and deliverability. Pages that are maintained collectively are published under SimplyRCS rather than a personal byline, and a personal name appears only on work that person actually did. Our editorial standards set out how topics are chosen, how statistics are sourced and labelled, and how corrections are handled.
