I worked for about 6 months at MemSQL while we were selling our startup Theneeds (and now I have a full time job while launching SoloKeys, so I can see also the "growing your startup" option).<p>My experience with MemSQL has been awesome on every possible level, before, during, and after.<p>I found the job via regular application process + interview, they were searching explicitly for part-time, so I'd recommend looking for that. I strongly recommend no conflict of interests of any sort, I was doing QA at MemSQL, they knew about my startup where I was doing content recommendation/machine learning/backend+web.<p>Aside from money, it's been great to work with another startup that: 1) was a US company (vs we were all Italian founders), 2) was in a more advanced stage (so, potential to learn about processes), 3) was and is full of great talented employees (so, great connections that we're still keeping alive).
