BUILD · AI Voice Developer Programme
Build and validate your AI Voice service
BUILD helps credible early-stage AI Voice businesses develop and test their service on real UK numbers before committing to a commercial wholesale number estate.
What's included
3 UK numbers for development and testing
Direct delivery into a supported AI Agent platform
Limited concurrent calling capacity for testing
Direct engineer support from our team
Onboarding into the wholesale approval process
A defined migration path to LAUNCH
A 60-day development period
Commercial terms
£75activation fee
Charged when you are accepted onto the programme. There is no monthly charge during the 60-day development period.
Upgrade to LAUNCH within the 60-day development period and the full £75 is credited against your first LAUNCH invoice.
Is BUILD right for you?
BUILD is not a free trial or an open-ended low-cost service. It is a selective, time-limited programme for businesses with a realistic path to commercial deployment.
A great fit if you are
Developing a commercial AI Voice service
Planning to deploy agents for your own customers
Working towards a launch date
Expecting to need UK numbers at volume
Probably not the right fit if you need
A number for a hobby project
A proof of concept with no deployment plan
Unrestricted SIP termination
Only a handful of numbers indefinitely
For one-off numbers or experiments, a retail CPaaS provider is likely to be a simpler option.
Applying for BUILD
Places are by application only. We ask a short set of questions so we can understand your service and give you a documented decision. Here is what we'll ask about:

Online applications are coming soon
In the meantime, book a call and we will take you through the application.
From BUILD to LAUNCH
During your 60 days, test inbound calling, agent behaviour, routing, workflows and the experience your customers will get. When you are ready to onboard commercial customers, move to LAUNCH: 100-number provisioning capacity, 50 shared concurrent channels, fixed monthly pricing and draw-down access to numbers, with your £75 activation fee credited.
