My successful startups had their own internal CRM as distinguishing factor to their success, it's not hard.

One started out as an acquisition of a group on sales force, we wrote migrated to our brand new crm the first month and integrated our PBX and several other functions within the first 3 months.

It's not hard, most CRMs don't need "webscale", you can whip up a highly targeted and integrated CRM in rails in the blink of any eye.

That's why I'm pretty sure in 2001/02 I had the earliest real customer, real time, audio reviews published online in the world.

Like any decision during a startup buy/build is a situation specific decision you have to make at every point and 3rd party CRMs are fine to launch with... but, I mean, come on.
