Customer Testimonials
More important than the list of logos is the impact we have had with their customers. Here is what our customers’s customers say:
“The fact that they hired you, an independent 3rd party, to look into this is impressive, it should have happened sooner.”
“What they have you doing demonstrates the type of company they aspire to be. When it’s time for renewal, if they address the issues I’ve had, and based on the value they put on you doing this, I would consider them again.”
“It felt therapeutic talking to you and doing this, I’m glad I did this. I can’t believe that you got me to talk for 54 minutes.”

FAQ’s
Find answers to common questions about Thirdside’s services and methodologies.
How can Thirdside help?
Thirdside helps B2B companies uncover the true reasons they win or lose deals. We provide independent Win-Loss Analysis, Customer Experience, and Churn Research to identify blind spots in your revenue engine, product roadmap, and competitive positioning that internal teams often miss.
What sets Thirdside apart?
Unlike automated survey platforms or typical consulting firms that tend to be too academic, Thirdside uses experienced sales and marketing leaders to conduct interviews. This peer-to-peer approach builds trust with executive buyers, eliciting candid feedback and strategic insights that standard surveys cannot capture.
How does Thirdside conduct interviews?
We conduct conversational executive interviews (typically around 45 minutes) rather than reading from a script. Our interviewers use a semi-structured guide to probe on decision drivers, pricing sensitivity, and competitive comparisons, ensuring we capture the “why” behind the decision.
What types of analysis does Thirdside offer?
We specialize in three core services: Win-Loss Analysis (for new customer acquisition, ICP refinement, and messaging), Churn Analysis (to understand customer attrition), and Customer Experience (CX) Research (to improve retention and expansion).
How can I get started?
Schedule a consultation to discuss your current revenue blind spots. We can design a pilot program—often starting with a specific segment of recent deals—to demonstrate the immediate value of unbiased customer intelligence.
