An AI-native sales team, built on Allo
Tamtam builds its customers a perfect lead list every Monday, using unique buying signals from past won deals along with all the context reps need to convert. It is a SalesTech company through and through, and its own sales team runs entirely on Allo.
Allo is the first and only phone system Tamtam has ever used. They adopted it at the company's founding, the moment they brought on their first sales reps, and they have never looked back.

Allo across the whole customer lifecycle
Tamtam uses Allo at every stage. The entire sales team cold-calls through it. Account Executives use it to engage prospects throughout live deals. And the customer success team uses it to stay close to customers and run success check-ins.
It all connects to HubSpot, which sits at the center of how Tamtam operates. The sync between Allo and Tamtam's contact records is what keeps the process clean and reliable.
Allo is the first and only VOIP we've ever used. We adopted it at Tamtam's founding, right when we brought on our first sales team, and we've never looked back.
Context is the biggest change
As an AI-native company, Tamtam gets the most out of having every call transcribed. It means they keep the full history of every conversation with every customer, and that context feeds directly into how they work.
The before and after is stark. Tamtam went from a company with almost no sales processes or tooling to one with clean processes, a well-structured HubSpot CRM and a professional calling setup. When the first reps were onboarded, Allo was part of giving them everything they needed to close, and it gives the customer success team the same professional setup to talk to customers.

Call quality is the feature we're most demanding about, and Allo is clearly best in class. The HubSpot integration is the other one: the sync with our contact records is what keeps our processes clean and reliable.

Betting early, and it paid off
Tamtam got started with hands-on help from Adrien on the Allo team, who onboarded them, walked them through the setup and got them their first numbers. They were among the first SaaS customers running Allo with the HubSpot integration.
They knew they were betting on a young product, but one with huge potential, and they deliberately avoided the legacy players. The bet paid off. The Allo team gave them hands-on technical support throughout, fixed bugs fast, and shipped improvements based on their feedback.
