Reviews Summary

The overall sentiment for Optimizely and its associated Zaius platform is mixed, with reviewers noting both substantial positives and significant concerns. Many users highlight issues such as declining customer support quality, slowed product development, complicated manual processes, high prices, and aggressive enterprise-focused pricing changes. However, several reviews also mention positive interactions with friendly staff and enjoyable facilities, suggesting strengths in workplace atmosphere and event hosting.

Frequent themes across the reviews include dissatisfaction with customer support transitions and platform updates, especially after corporate changes. Users repeatedly mention challenges related to pricing, billing, and perceived neglect of product innovation. In contrast, positive patterns emerge from comments about the physical office space, the helpfulness and friendliness of staff, and the vibrant company culture at events and within the office environment.

Overall, Optimizely’s reputation appears to be divided: business software users in particular express frustration with service and cost, while others offer favorable commentary on the company’s in-person environment and staff. This results in a credible yet mixed standing within its industry.

Zaius has been going downhill since optimizely took over. I asked for a new rep because my new rep that told me he had trouble with follow up never followed up. The new customer support chat feature is not as good as it used to be. I think the campaign reporting got downgraded a bit. Customer profiles and segments still take too long to load. Manually uploading customer lists is still a difficult process. I am NOT seeing many new features. A competitor reached out recently and they had an "optimize" feature for email send times and the email sends to that customer based on the time of day they typically open their emails. I just don't believe the Zaius product has received much development attention since optimizely took over.

Optimizely is a terrific, innovative service. But their pricing is outrageous. They regularly overbill customers by thousands of dollars (if you go over your usage quota). They recently raised their prices dramatically. They decided they don't want individual websites and instead are going after huge enterprise sales. You can't justify a $1 billion valuation with $199/month sales, I guess. I think they want more than $3000/month just for our 5 million pageviews. I switched to SplitOptimizer. It's not nearly as fancy as Optimizely, but it works perfectly. It's less than 1/10th the cost.

I use Optimizely and I totally recommend this tool for A/B testing. They have a sophisticated platform and it is clear that a proficient team of qualified developers is behind this awesome tool.
