About Wesype
Wesype accelerates AI transformation for SMBs and mid-market companies. As Dust's first partner and the operator of its European partner network, the firm supports clients end-to-end: use case diagnosis and design, solution selection, configuration, team training, deployment, and continuous improvement. Wesype combines methodological rigor with deep technological expertise.
Founded in the summer of 2024 by Guillaume Linet and Guillaume Luscan, both graduates of École Centrale Paris with backgrounds in strategy and operations consulting, the firm has established itself in under two years as the leading AI integration partner in France.
And all of their sales operations run on Allo.

The Challenge
The need, A phone system worthy of an AI consulting firm
Wesype's sales team lives inside HubSpot. Every SMB or mid-market prospect they engage, every AI transformation project they scope, every deal they close runs through their CRM. When you're leading AI projects for French companies, the phone is still where trust is built and decisions are made.
Jean-Romans, one of Wesype's two sales reps, had used Aircall in his previous role at Agicap. His verdict was clear: limited Hubspot integration, rigid workflows, copy-pasting phone numbers, manual note-taking, and calls sometimes logged to the wrong contacts.
For a firm that advises clients on AI-powered automation, there was no way they'd settle for that kind of experience. Wesype needed a tool natively integrated with Hubspot, with AI built in, from the start. That's why they went straight to Allo.

The Solution
A phone system natively integrated with Hubspot
The Hubspot integration worked seamlessly from day one: every call is recorded, transcribed, summarized by AI, and synced directly to the right contact in HubSpot. Zero manual data entry. Zero copy-pasting numbers. One click on a contact and the call starts.
The team immediately embraced click-to-call: clicking directly on a phone number in a Hubspot contact record to start the call. The call is automatically logged to the right contact, and the AI summary appears in the CRM timeline without anyone lifting a finger.
For Jean-Romans, the difference with his Aircall experience at Agicap is striking: a far smoother integration, a simpler interface, and most importantly, no more manual work around calls.
Adrien from the Allo team even offered to customize the AI summary prompt to match Wesype's specific sales methodology. That level of personalized support made the difference.
"Having experienced the Hubspot and Aircall combo at Agicap, Allo is far more intuitive. The integration is better, you launch the call directly from the Hubspot contact."

The Impact
An AI firm that practices what it preaches
Today, Wesype's entire sales team runs its outreach on Allo. Every call to a prospect or client is automatically recorded, transcribed, and pushed into Hubspot.
For Matthias, who joined the firm with no prior experience using a VoIP tool, Allo delivered exactly what he expected from a phone solution. The Hubspot sync works flawlessly, and the AI summaries give him everything he needs to prepare his follow-ups without having to piece together notes after a call.
The team also values Allo's responsiveness. When small issues come up, the Allo team steps in quickly through a dedicated Slack channel, with same-day resolutions. For a fast-growing firm that can't afford downtime on its sales pipeline, that matters more than feature lists. Using Allo means practicing what they preach: letting AI handle the admin so consultants can focus on the conversations that create value.
"Honestly, it's a great help. Everything I expected from a call recap tool. The integration with Hubspot is excellent."

Why Wesype Chose Allo
Guillaume's team had direct, hands-on experience with both platforms. Here's what made the difference:

HubSpot Integration: The Dealbreaker
For Wesype, HubSpot isn't just a CRM. It's the operating system of their sales team. Every reseller they onboard, every enterprise client they nurture, every deal they track lives in HubSpot. A phone system that doesn't integrate perfectly is a phone system that doesn't work.
The HubSpot integration is flawless. It really meets our needs. I find the whole experience very fluid.
