Created by The Mobile-First Company, Allo is a business phone system that main street teams and AI agents run together. Allo provides the phone numbers, and people and agents share the same workspace: the team stays on the important calls while the agent answers the overflow, texts customers back after missed calls, books appointments, and updates the CRM, day and night. The AI is not a layer added on top: the agent is part of the phone system itself, working with the same numbers, history, and tools as the team. Every call is recorded, transcribed, and summarized automatically.
The platform serves around 10,000 businesses across the US and Europe. It is, as co-founder and CEO Jérémy Goillot put it, the biggest alternative to RingCentral today.
Two years ago, Allo was running on Vonage. The product worked. The friction was in the operational details, the things that matter when you scale.
"The main motivation was around 10DLC," Jérémy said. "I believe you are the only API-first providers. At Telnyx, you can see that everything is done for the API."
The contrast was stark. With Telnyx, Jérémy could register 10DLC brands and campaigns programmatically through the Messaging API. With Vonage, he had to upload spreadsheets through a portal.
"When people start to build on top of voice and telecommunication, they focus a lot about how can I get the numbers, how can I send the text," he said. "But when you start to scale and you're serving more than a thousand businesses, you really need to be good in the details about porting, about 10DLC, about spam, all these little APIs that none of them have. Telnyx does."
The migration started with a self-serve approach. Jérémy's team opened the Mission Control Portal, moved some of their US volume over, and connected with Telnyx engineering through a shared Slack channel. A dedicated engineer handled the integration.
"In terms of timing, I think it took us around six weeks to be able to provide mobile Phone Numbers with texting capability in the States," Jérémy said. "The process was straightforward."
The biggest challenges, he noted, were not technical blockers. They were the operational questions that always come with voice: how to track calls, how to route them, how to handle the edge cases. Having direct access to Telnyx engineers through Slack made the difference.
The switch to Telnyx had a direct effect on what Allo's customers experience. 10DLC onboarding, which previously took months, now takes less than a week. Brand verification completes in under three minutes. Campaign registration takes less than five days.
"I think that's the best in the market standard today," Jérémy said, "both coming by how much work we did on automation for the main street business, but also how active is the API and webhook of Telnyx."
The second improvement was in number availability. Main street businesses are particular about their phone numbers. They want toll-free numbers, or specific area codes like 212 in New York or 305 in Miami. Through Telnyx, Allo maintains a large catalog of Phone Numbers to match what customers ask for.
"We always have a huge catalog to be able to provide the right phone numbers they need," he said.
Jérémy, who has worked with the five biggest telecom providers, said the experience with Telnyx is fundamentally different.
It starts with the human relationship. Where larger competitors treat a customer as one of thousands with no direct point of contact, Telnyx assigned a consistent person who knows the account.
"You have a human in the loop all the time," he said. "And the human has a name, and it's always the same person."
That consistency carries over to pricing. With Telnyx, what you see on the platform is what you pay. Every line item is documented. He could project his costs without surprises, something he could not do with competitors who obscure which countries are supported, which numbers are available, and what the actual costs are.
"You can easily project about how much you will pay."
Then there is the platform itself. Jérémy drew a sharp line between Telnyx and Vonage.
"If you just compare the Vonage platform and the Telnyx platform, you can see which one has been built by engineers and which one has been built by telecom people," he said. "The Telnyx platform is world-class."
