Funds would go mainly towards development of new features as mentioned above, and perhaps a bit towards getting assistance from a professional designer.

It is unlikely that we would spend much or anything on any kind of marketing, as the goal is to achieve viral growth from word of mouth, by making rolod0x so useful and easy to use that it becomes a complete no-brainer for everyone to use it :-)

There are no plans to monetize rolod0x.  It was built as a public good to improve web3 UX and therefore help scale web3 adoption.
