About Wesype
Wesype is France's first value-added distributor specialized exclusively in AI solutions for business. Founded in summer 2024 by Guillaume Linet and Guillaume Luscan, both graduates of Ecole Centrale de Paris, the company helps IT resellers and integrators deploy AI tools for their clients.
Before founding Wesype, Guillaume Linet spent over four years as Chief of Staff to the CEO at Spendesk, one of France's leading fintech unicorns. He helped grow the team from 20 to 700 people and supported more than €250M in fundraising, multiplying ARR by 50x. That operational DNA shows in how Wesype operates: lean, fast, and deeply embedded in the tools they sell.
As the first Platinum Partner of Dust (the French agentic AI platform co-founded by ex-Stripe engineers), Wesype distributes and integrates solutions including Dust, Maven AGI, 11X, and Mojo. With 130+ clients, 10 certified experts, and a growing sales team hiring 15 people in Lisbon, Wesype is scaling fast.
And their entire sales operation runs on Allo.

The Challenge
From Aircall to Something That Actually Works with HubSpot
Wesype's sales team lives inside HubSpot. Every AI reseller partner they onboard, every enterprise prospect they nurture, every deal they close flows through their CRM. When you're selling AI transformation projects to French SMBs and mid-market companies, the phone is still where deals happen.
Before Allo, the team had experienced Aircall. The veredict from Guillaume was clear and immediate: the HubSpot integration wasn't cutting it. You couldn't even launch a call by clicking the phone icon on a contact. The workflow felt disconnected, clunky, and manual.
Guillaume found himself copy-pasting phone numbers from HubSpot into the dialer, a workflow that felt completely backwards for 2025. Manual note-taking after calls, no AI summaries, and an integration that occasionally logged calls on the wrong contacts.
For a company that literally sells AI-powered automation to its clients, using a phone system that required this much manual work felt like a contradiction.

The Solution
A Phone System That Speaks HubSpot Natively
Wesype switched to Allo and the difference was immediate. The HubSpot integration clicked into place: every call is recorded, transcribed, summarized by AI, and synced directly to the right contact in HubSpot. No manual logging. No copy-pasting numbers. Just click a contact and call.
Guillaume discovered what he described as his "click-to-call moment": clicking directly on a phone number inside a HubSpot contact record to launch the call. Something that felt broken on Aircall but works naturally on Allo. The call logs to the right contact automatically, and the AI summary lands in the CRM timeline without anyone lifting a finger.
Adrien from the Allo team even offered to customize the AI summary prompt to match Wesype's specific sales workflow. If the default summaries are too long or don't capture the right data points, a simple prompt change adjusts the output for the entire account. That level of hands-on, personalized support sealed the deal.
Having used HubSpot on its own and then with Aircall, Allo is far more intuitive. The integration is better designed. With Aircall, you couldn't even launch a call from the phone icon.

The Impact
An AI Company That Practices What It Sells
Today, Wesype's sales team all run their prospection through Allo: Guillaume and Jean-Romans in Paris, Matthias in Lisbon. Every call to a potential reseller partner or enterprise client is automatically recorded, transcribed, and pushed to HubSpot.
For Matthias, who joined Wesype without any prior VoIP experience, Allo delivered exactly what he expected from a modern call tool. The HubSpot sync works seamlessly, and the AI summaries give him everything he needs to follow up without scrambling for notes after a call.
The team also values Allo's responsiveness. When small issues come up, the Allo team jumps in fast through a dedicated Slack channel, with same-day resolution. For a fast-growing startup that can't afford downtime on its sales pipeline, that matters more than feature lists.
There's a credibility play here too. Wesype sells Dust, Maven AGI, and 11X to companies looking to automate their operations. Using Allo is practicing what they preach: letting AI handle the administrative work so humans can focus on the conversations that close deals.
Honestly, it's a great tool. Everything I expected from a call recap system. The HubSpot integration is really good.

Why Wesype Chose Allo Over Aircall
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.
