Statwing has been acquired by Qualtrics

Great news: Statwing has been acquired by Qualtrics.

Qualtrics’s goal is to make sophisticated survey-based research simple. Statwing’s mission has been to make sophisticated data analysis simple. So it’s a great fit.

Statwing will live on, and we’re confident that having Qualtrics’s resources at our disposal will allow us to move much faster, build a better product, and reach many more people.

Statwing will be available in its current form to subscribers until December 31st, 2016. After this date, it will be integrated into Qualtrics and subscribers will have the option to switch to the new platform to continue using Statwing in its improved form (whether or not you’re analyzing survey data).

If you’re not already a customer, get early access to Statwing-on-Qualtrics by signing up here.

Thank you for being a part of Statwing. We’ve had an incredibly positive experience talking to, learning from, and serving our users. And we look forward to continuing to do so as Statwing joins Qualtrics.
