We’ve been using CustomFit.ai on our Shopify store for a few months now, running multiple A/B tests and personalisation experiments. The setup is incredibly smooth changes go live instantly and there’s absolutely no impact on site speed. The platform has helped us drive clear improvements in engagement and conversions, and we’ve been able to execute experiments faster than ever. A special shoutout to their team they’re super responsive, proactive, and always quick to resolve any issues. Even our last-minute or ad-hoc requests have been handled promptly without any follow-up needed. Overall, a great partner for growth and experimentation. Highly recommended!
