The general advice you will get around here is that ideas are cheap, execution is hard. Many who started out believing they needed to protect their ideas end up in the camp of openly sharing them. My understanding is that most angels and VCs will refuse to sign non-disclosure agreements or non-competes; not because they wish to steal your idea, but because they do not want to get legally entangled. Imagine VC firm turning down an entrepreneur for idea "A" because the market didn't seem quite ready and they didn't have a strong team of founders. Now 9 months later another entrepreneur approaches the VC firm with idea "B" which overlaps with "A" about 80%. The market is changing in a positive direction, the 20% difference seems to solve certain problems and by the way the founding team is much stronger. If the VC firm wants to be able to fund the best team regardless of whether this was the first or the fifth time they have heard roughly the same idea. Instead of capital, you may try to seek a technical co-founder. But that is not as easy as you might think either.
