I worked for an ISP (Berbee or BINC) that was merged with CDW. It was exactly as outlined above -- the private equity company had a big stake in both and merged them together for a later IPO.

In my experience, it was painful because a small highly technical organization was smashed onto a huge sales-centric company. The cultures were not the same at all. It wasn't horrible and I wasn't there long enough to benefit from anything (the Berbee founder gave some ownership to people who had been there longer -- my stay was brief during and after college so it was fine by me). But the resulting company wasn't as interesting to work at and today many of the people I knew who worked there moved on to other competitors in the local market. Nothing wrong with change but it was an awesome company before the merger.

So you might expect in the future to be merged with a company that looks good on paper but is painful in practice. But of course from the PE viewpoint, the point is to make money so as long as that happens, it's a win. It's just their interests are probably not aligned with yours.
