<i>What kind of demos do you think would impress best-in-class recruits&#x2F;investors to join our team</i><p>All the options you mention would be technically impressive (so good for recruiting hackers), but none of them are obviously on the path to building a huge business. You should lean towards the option where you can imagine having a near-monopoly in a huge market.<p>There&#x27;s a big danger of getting sucked into some application where better NLP isn&#x27;t the differentiator. Most interactive agents have small enough domains (getting cable TV installed, parsing S-10s, triaging support emails, ...) that general reasoning isn&#x27;t critical, and the companies that succeed in this space will be defined by other factors like sales and integration with the customer&#x27;s IT stack.<p>I wouldn&#x27;t worry about IP leakage. I&#x27;ve seen a lot of companies, but none that failed because of IP leakage. They fail for a long list of other reasons: slow execution, bad product-market fit, founder breakups, etc.
