Stop guessing what your prospects and customers think. Access reality.
Diffly conducts qualitative interviews directly with your prospects and customers, as a trusted neutral third party, to capture the real feedback your buyers would never share with you directly.
The result: you get the ground truth behind every purchase decision.
With Diffly, we’ve not only improved our sales efficiency but also instilled a data-driven culture within our teams. The insights generated are now at the heart of our decision-making, whether in sales, marketing, or product development. It’s a real game-changer for our company.

Before Diffly, we had ideas about what worked and what didn’t, but nothing tangible to support our decisions. This allowed me to deliver some very strong messages internally, and it helped the teams become aware of things they hadn’t even considered.

The problem
Your reps report their version of events. Rarely the prospect's.
And no one ever truly interviews the buyer with the neutrality needed to get an honest answer.
You're missing the critical insights that could be boosting your revenue
Your strategic decisions are built on internal bias
Your CS platform tracks usage metrics, not what your customers actually think.
4 to 5
Decision criteria that determine the outcome of every opportunity. (Gartner, 2024)
Features
What Diffly actually does for you
Diffly conducts qualitative interviews on your behalf, in complete neutrality
Buyers speak more freely to an independent third party. You get honest answers on why they chose a competitor, what held them back, how much price actually weighed in, and what could have changed their decision. No more assumptions. Just facts.
Diffly handles all the logistics and delivers actionable analysis
Every interview follows a framework designed to surface real decision criteria. Each conversation is turned into clear insights: recurring objections, the arguments that convince, the elements that work. Average response rate: 40%.
Diffly analyzes all interviews and alerts you to recurring trends
Instead of isolated anecdotes, Diffly identifies the patterns that emerge across multiple deals: Why are you losing to [competitor X]? What objection is blocking your largest deals? Is this customer going to churn in 5 months? Diffly acts as a neutral extension of your team, dedicated to the truth on the ground.
Always-on
Never miss a real reason again.
