Dev Bootcamp, a coding school with six locations around the U.S., including Seattle, will close its doors in December.

The company, which was founded in 2012 and offers short-term intensive programs in subjects like web development, said in an email announcement that “despite tremendous efforts from a lot of talented people, we’ve determined that we simply cannot reach a sustainable business model without compromising our mission of delivering a high-quality coding education that remains accessible to a diverse population of students.”

Dev Bootcamp said it won’t be taking on any new cohorts after July 17, but it will continue supporting people currently in the program. Additionally, the school will provide students still going through the program six months of support services following graduation.

Dev Bootcamp said it has graduated more than 3,000 students over its five years of existence across its six campuses in Seattle, San Francisco, New York, Chicago, Austin and San Diego. Dev Bootcamp was acquired by education powerhouse Kaplan in 2014.

Dev Bootcamp further elaborated on its closure in response to questions on Twitter this morning.

1. Thanks for your thoughts, Darrell. The fact of the matter is, Kaplan made a huge investment in us by acquiring an unprofitable business. — Dev Bootcamp (@devbootcamp) July 13, 2017

2. It is really the reason we were able to focus on teaching our students for as long as we did & experiment with different delivery models — Dev Bootcamp (@devbootcamp) July 13, 2017

3. as well as products. In the end, DBC needed to balance quality, access & financial viability. We weren't going to sacrifice the first two — Dev Bootcamp (@devbootcamp) July 13, 2017

Coding schools have been popping up all over the place in recent years as the demand for tech skills has skyrocketed. According to last year’s Coding Bootcamp Market Sizing Study from Course Report, there were 91 full-time coding schools in the U.S., up from 67 the year before. Coding schools were set to graduate 17,966 students in 2016, up from 10,333 in 2015.

But with so many of these schools opening up in recent years, the industry is bound for a shakeup at some point. And while the industry continues to grow, it’s not all good news as shown by the coming closure of Dev Bootcamp, and some recent layoffs at rapidly growing Coding Dojo.
