How Prismfly and KnoCommerce Teamed Up to Drive a 10.2% Revenue Lift for CrunchLabs

When Prismfly, a conversion-focused ecommerce optimization agency, teamed up with KnoCommerce to support CrunchLabs, the work did not start with headline ideas or copy tweaks. It started with insights.

CrunchLabs had a strong product and loyal customers. The challenge was ensuring the homepage clearly conveyed the value new shoppers cared about most.

Instead of relying only on CRO best practices or assumptions, Prismfly leaned into post-purchase feedback collected through KnoCommerce to understand what influenced real buying decisions.

Using post-purchase and NPS data to guide the test

With post-purchase responses and Net Promoter Score (NPS) data revealed through KnoCommerce, Prismfly conducted a qualitative review of customer language, confidence drivers, and objections.

For one, customers consistently referenced trust signals, incentives, and clarity around value. Some of those signals were present on the homepage, but others were buried or missing entirely.

Rather than treating feedback as anecdotal, the team evaluated recurring themes and mapped them to known conversion levers across trust, clarity, and incentive strength.

These findings informed hypothesis creation and prioritization.

Testing what customers said mattered

Prismfly designed a controlled homepage experiment that focused on messaging as the primary lever, while keeping design, layout, and page structure consistent. This allowed the team to evaluate how different customer-driven signals influenced conversion without introducing noise from visual or structural changes.

Across three variations, Prismfly tested a mix of copy elements informed by post-purchase feedback. These included social proof such as a 4.8-star review, validation through a 98.5 percent customer satisfaction score based on Net Promoter Score (NPS) data collected through KnoCommerce, incentive-driven messaging like a chance to win an 80,000 dollar college tuition giveaway, and adjustments to how sustainability messaging was positioned.

Throughout the experiment, Prismfly evaluated how these signals worked together to reduce hesitation and build purchase confidence, using customer language and feedback to guide prioritization and iteration.

What happened next

Highlighting what mattered most to customers delivered measurable gains:

• Conversion rate increased by 4.7%

• Revenue increased by 10.2%

The improvement came from aligning homepage messaging with what customers had already said mattered to them.

Where the partnership mattered

According to Dziugas Alminas, Head of CRO at Prismfly:

“Here at Prismfly, data analysis is the backbone of every experiment we run. We evaluate performance from multiple angles, including quantitative and qualitative data, heuristics, customer support insights, and post-purchase feedback.

Post-purchase responses reveal what customers felt was missing. That input helps us form stronger hypotheses. For CrunchLabs, addressing those gaps earlier in the journey improved both the experience and the metrics that matter.”

In this case, KnoCommerce made it possible to access high-signal post-purchase feedback tied closely to customer intent. Prismfly used that context to decide which messages to elevate, which confidence signals to prioritize, and how to structure the test within the customer journey.

What Prismfly is carrying forward

This experiment did not introduce new concepts for Prismfly. It reinforced a data-driven approach they already apply across client engagements.

Customer feedback is most valuable when it informs prioritization, not just reporting. Experiments are strongest when hypotheses are grounded in real customer language. And CRO work delivers the most impact when insights and execution stay tightly connected throughout the customer journey.

In the case of CrunchLabs, post-purchase feedback helped sharpen which confidence signals were worth elevating and which levers were most likely to influence a purchase decision. Prismfly applied the same CRO discipline they bring to every engagement, using customer insight to guide focus and testing with intent.

The lift came from applying a proven methodology with sharper insights.

A look inside the KnoCommerce and Prismfly partnership

When Prismfly partnered with KnoCommerce to support CrunchLabs, the biggest beneficiary was the client.

KnoCommerce enabled access to high-signal post-purchase feedback tied closely to CrunchLabs’ mission and audience, including insights related to Mark Rober’s focus on increasing children’s interest in STEM.

Prismfly analyzed and interpreted that feedback to determine which customer concerns and outcomes warranted priority within the CRO roadmap.

Prismfly applied its CRO expertise to that context, determining which levers were most likely to influence purchase behavior. As they evaluated the highest-impact levers they could pull for CrunchLabs, they shared how they think about prioritization, testing, and where CRO effort is most likely to drive meaningful results.

That exchange shaped how hypotheses were formed, which confidence signals were prioritized, and how experiments were structured within the customer journey.

This triangulated approach led to more actionable feedback and made it easier for Prismfly to do their best work for a shared client.

The result was a more connected approach, clearer direction, and better outcomes for the brand.

By combining Prismfly’s CRO expertise with KnoCommerce’s post-purchase insight, CrunchLabs was able to tighten its messaging, reduce friction for new shoppers, and turn customer feedback into real revenue impact.
