The investors always protects their own interest - remember that. They not only bet on the technology, but also on the people behind it. Depending on the agreement, the investor might not "owe" you anything. Thus, if they invested in another product in the same emerging market, they're trying to ensure greater % of success and ROI for themselves.<p>But, you do "owe" things to an investor - like reports, hard work etc. What you do, however, OWE to yourself is that you protect your idea/product to the fullest.<p>Thus, you only feed them what they need to know, thus disclose only relevant financial info. If they ask for other info be sure to be brief. Don't disclose the actual details about the tech behind it.<p>I assume if you know who they invested in, you know the amount and probably the terms, thus assess. More investments > higher risk > higher reward. If those investments were <250k, that's normal and I wouldn't be to worried about it.
