There are also other permissive open source licenses which supports open
and closed source software.

Ruby and JavaScript projects many times use MIT license.
For example, see Ruby on Rails (http://rubyonrails.org/) or JQuery
(https://jquery.org/license/).

Java and JVM -based projects often use Eclipse License.
Examples: Eclipse IDE itself, Clojure (http://clojure.org/license).

Personally, I prefer ISC license (basically simplified BSD), which comes
from Internet Software Consortium (home for BIND & stuff).
Example: OpenBSD; Ahven, my unit testing library for Ada
http://www.ahven-framework.org/LICENSE.txt

There are some wording differences between these licenses (Boost, MIT,
Eclipse, ISC), but generally they are compatible with each other and you
can include the code to closed source software without needing to
release the source code. (Of course, there might be some exceptions;
check the licenses first before combining code with different licenses.)

Yours,
