Two products that use the phone, for different reasons
At Allo, the phone is the product. At Flunter, the phone is a lever.
Our business is not to let your company make phone calls. Our business is to let your sales reps sell more.
This difference completely changes the way we develop Flunter. Every feature is evaluated by one question: will this allow sales reps to spend more time talking with prospects?
Allo helps companies manage their communications better. Flunter helps sales reps have more conversations with their prospects.

The real cost of prospecting
Many companies try to reduce their software costs. We think that's the wrong approach.
The largest expense of a sales team isn't its phone subscription.It's the time of its sales reps.
A Business Developer costs tens of thousands per year. If they spend half their time dialing numbers, waiting for rings, hitting voicemails, or calling the same prospects back: that's time creating no value at all.
A minute spent in conversation is worth infinitely more than a minute spent waiting for a phone to ring.

Why our Parallel Dialer changes the game
This is probably the most important difference between Flunter and a traditional phone system.
Our Parallel Dialer can call up to five prospects simultaneously. While calls are running, voicemails are detected and ignored, unanswered calls are automatically dropped, and as soon as a prospect picks up, the sales rep is connected immediately.
This isn't just a comfort improvement. It's a complete productivity shift. For teams prospecting several hours a day, this can represent several hours saved every week.

Built by sales people, for sales people
Flunter was born from a simple observation. Sales reps were losing enormous amounts of time between conversations. Dial. Wait. Voicemail. Dial again. Wait. Start over.
Our Parallel Dialer, Power Dialer, proprietary detection and CRM integrations all pursue one objective.
Make your sales reps talk more.

We follow two different roadmaps
Some solutions offer features we're also building progressively: full mobile app, advanced telephony, call collaboration.
We'll build them. But in the right order.
Our priority has always been to develop the features with the most impact on sales performance first.
Our Parallel Dialer
Our Power Dialer
Our proprietary voicemail detection engine
Our CRM integrations
An extremely simple-to-use interface
We prefer to add features once they're truly ready, without compromising the product's simplicity.

Our obsession is not to make more calls. Our obsession is to give your sales reps more time in conversation with real prospects.

Frequently asked questions
Allo and Flunter both offer a Power Dialer, AI and CRM integrations. Flunter also runs up to 5 calls at once with its Parallel Dialer, while Allo is built for sequential calling. Allo goes further on business cloud telephony and the mobile app, two areas still in development at Flunter.
It depends on your objective. If you mainly need a cloud telephony solution to manage your company's communications, Allo addresses that need. If your priority is improving your commercial prospecting performance, Flunter was built specifically for that use case.
Because we believe the main cost of prospecting is your sales reps' time. Every minute saved between conversations directly improves your team's productivity.
Yes. We offer multiple pricing tiers to support both sales reps who prospect a few hours a week and Business Development teams that prospect all day.
A Power Dialer dials numbers sequentially, one at a time. A Parallel Dialer like Flunter dials multiple numbers simultaneously (up to 5) and connects the rep as soon as a prospect picks up. This multiplies useful conversations per hour.
