Competitor spying bot. Useful?

Just had the idea for a $30/mo bot that can do competitive intelligence for you.

You give it a list of competitor sites and it will alert you for:

1. New product/feature launch by competitors
2. Pricing updates by competitors
3. Funding of competitors
4. Events organized by competitors

You should be able to filter what alerts you want like "new product", "funding", "pricing" etc.

Any other data or use cases you'd be interested in?

Thanks
