Maybe this is ad hominem, but it seems to me they must've raised a lot of money to prioritize that kind of setting, likely in the guise of recruiting. Crunchbase lists them as having raised $251.2M and their last round being debt financing.
If this is a down-round acquisition with most of the employees gaining very little I wonder if this is a lesson to founders to be more cost-effective and raise less money.
I can't speak for all industries, but for the ones I'm familiar with, marketing is always the product owner of websites. With two practical implications being
1. The entire website costs (development + software vendors) ultimately get booked against their budget, so they have the true purchasing authority for pretty much all the website tech that isn't centrally mandated/controlled
2. Website projects (including budget and requirements planning) tend to start in marketing loooonnnggg before a tech resource gets brought in. So developer awareness/familiarity ends up moot, since there's too much incremental effort and cost involved for it to be easily get buy-in and added to the plan at this stage.
It makes a ton of sense to target your solution at them instead of developers. They may not be able to use your product well or do the implementation, but they're the ones with the purchasing authority and ability to ensure the budget accounts for it. And can add it into the project requirements far earlier in the planning stage than when tech resources get involved.
No one I know has deployed Optimizely since 15/16.
Any roll-your-own experimentation platforms take considerable resources to make accessible to those in the organization interested in using it (product, marketing, etc.)
However, we found that those interfaces only allow very limited, shallow tests and you very quickly outgrow them as an organization. In other words, once you reach diminishing returns on button color and header text optimizations, you start wanting to test deeper UI experiences and complicated user flows. At that point, you have to involve engineering anyway.
When an organization has engineers who are motivated by business metrics, they have no problem implementing shallow tests (like button colors) while working on tests of the deeper UI experiences as well. And at that point, the non-technical interfaces have little value.
Metric + page management, results analysis, segmentation, etc. all work better in Optimizely than they do in other platforms.
Many players have jumped into this space with their own A/B testing and Feature Flags solutions as part of their total offering, many of those offerings being free, open source or cheaper. Also potentially better in the concrete tasks they enable. I doubt that Optimizely's feature flag offering is superior to something more specialized like LaunchDarkly.
Also there are a couple of strong incumbents' solutions like Google Optimize and Adobe Target and it's always hard to go against incumbents specially when the incumbents are coming after you and not the other way around.
One clear problem for Optimizely in this space is that experience optimization became a function of marketing departments through out the years but for a while they were positioning themselves as a developer tool. This go-to-market strategy opened a lot of opportunities for other players who saw a bigger market when selling the same type of solution to Marketing Departments.
Maybe I'm wrong but it seems that they just stopped growing and have been experiencing a lot of customer churn since this is likely an expensive product with a hard to calculate ROI. They're probably still selling a lot but nowhere near to the original investor expectations / close to becoming profitable.
