As an angel investor, I can anecdotally confirm that I've become more cautious recently (in the last year, really). However, I'm not at all concerned about the stock market. That has never influenced my decision to fund a company. My belief is that a strong company can weather a bear market. I'm concerned with the current state of valuations - I enjoy giving investments to companies on the order of five figures or so…
FWIW I'll back you up on this, definitely a complicating factor for novice investors.
Free tip to novice investors: If someone approaches you with a request for funding, if it is still 'just an idea' and if the idea will surely deliver billions and if the funding required is Anything that will grow to turnovers that high will surely require a little bit of traction after implementation before any figures can be projected at all and anything that hasn't been implemented yet doesn't even qualify to be discussed in other terms than hypotheticals.
Another free tip for novice investors: pair up with a more experienced investor to vastly reduce your chances of being ripped off on your first investment(s).
This is also not a guarantee but it will increase your odds considerably, it also requires you to convince another, hopefully more skeptical party that what you've found is really worth an investment.
