If you can't find any information on the company, you can say something like 'I'm really intrigued by the company and I'm really excited to learn more.' People love to talk about where they work. I think taking a look at the company Web site is good enough in this case. You can say 'I'm normally able to do some research about a company.' That is totally acceptable and can be a great conversation starter and connecting point. Once they start telling you about the company, you can say 'I worked on something very similar' and point to your experience.
