Thanks "funnel". I hate you.
Sincerely, Every Sysadmin who ever had to buy anything.
It's always pretty easy though to say "we like your product, but we want more information as to integration possibilities. Can you put us in touch with someone on your technical staff so we can ask these questions?"
Everyone company I've run into will at least give you an email contact, and all of the smaller ones (less than 20 persons employed) will just transfer you to the tech department directly.
I've done this with everything from hardware purchases to $7000/per cpu database software.
I recently tried to recommend a great product to my boss. I had used it in a past job, and I knew what company made it, but I had no idea what the actual product was called. I didn't want to waste my boss's time, so I tried to do the research on my own and figure out what specific product I was looking for.
Their website wasn't very helpful, it was filled with generic product names and an amalgamation of SEO-friendly keywords and the word "solution". I emailed them to find out which product I was looking for, and next thing I knew I was on a sales call. Then I was on a sales conference call. Then they popped in for a sales meeting, even though I never told them my company's address.
I came away with a vague idea that their products were both nameless and probably very good. I explained it all to my boss; he took a pass.
I could've saved everyone a lot of time if I just had that comprehensive datasheet.
Sigh, I'll miss the days when America made stuff :-|
So don't hate the funnel, hate the bad marketing material that has no technical relevance to your concerns, and the clueless sales force that does its clients a disservice every time they answer a question or make a technical promise.
