Why Teams Switch to Free Card Sort

Reason #1: Cost (Mentioned by 87% of switchers)

Common Objections Answered

"But Optimal Workshop is the industry standard"

Truth: Optimal Workshop was the standard when there were no good alternatives. Free Card Sort now provides the same core card sorting features at a fraction of the cost. Industry standards change when better options emerge.

Reality check: Most teams use less than 20% of Optimal Workshop's features. If you're only using card sorting, you're overpaying.

"We need tree testing too"

Solution: Use Free Card Sort ($0-$19/mo) for card sorting + a dedicated tree testing tool. Total cost: Still less than Optimal Workshop.

Better alternative: Many teams find card sorting + user interviews more valuable than tree testing alone.

"What about support and training?"

Free Card Sort: Email support, knowledge base, video tutorials Optimal Workshop: Same, plus enterprise account managers (at $449/mo+)

Reality: Most users don't need extensive support for card sorting. Free Card Sort's simpler interface means less support needed.

"Our enterprise needs SOC 2 compliance"

Fair point: Optimal Workshop has more enterprise security certifications. If you're in healthcare, finance, or government with strict compliance needs, Optimal Workshop might be required.

Alternative: Free Card Sort Enterprise plan offers SSO and enhanced security for organizations that need it.

"We've invested years in Optimal Workshop"

Sunk cost fallacy: Past investment shouldn't determine future spending. Your existing Optimal Workshop data exports to CSV and can be recreated in Free Card Sort in under an hour.

Forward thinking: How much will you save over the next 3 years? ($4,851 on Basic, $8,451 on Team, $15,651 on Professional)
