What is coda's vision?

Hi all, I am working with Coda for nearly 2 years (I think :thinking:) and just had yesterday another chat with the support, as we had troubles with some calculations. I was told that a Code should not have more then 1-2k rows in total, which leads me to the question: what is Coda being used for?

We use(d) it for our conference planning, having around 4k possible speakers only (sure, a contact is one row), not to speak about the activities/task, tags etc.

I would be more than happy to get your views, saying that we would be willing to pay for a pro-tier plan or something – as we like Coda very much.
