Having anything with GPL in it in a startup is a red flag during diligence. Goes double for Enterprise level. For that reason, most companies won't use GPL software or, if they do, they have it all "fire-walled" from all their other software. The fear is that someone inadvertently includes it in the companies other code and causes a huge legal mess. Or you patch something, and now you need a way to open source stuff -- companies are built to prevent code from leaving, getting stuff going the other way is a bureaucratic nightmare. Overall, even if you're complying with the GPL (using the software in an approved manner), it's not usually worth the hassle of proving you're complying with the GPL _in a way that is legally defensible_.
