Speed to Lead

An inbound lead — someone who filled out a form, requested a demo, or started a trial — is at their highest point of interest and attention at the moment they took that action, and that interest decays fast, often within minutes for a genuinely hot lead. The single most consistent, well-documented finding in inbound lead conversion research is that response speed correlates strongly with conversion, with the effect concentrated heavily in the first few minutes and dropping off sharply after roughly the first hour.

Why speed matters more than almost any other single lever

The lead's context at time of inquiry     actively evaluating,
                                          often comparing several
                                          options in the same
                                          session, attention high
An hour later                             may have moved on to
                                          another task, spoken to
                                          a competitor who
                                          responded faster, or
                                          simply lost momentum

A lead comparing several vendors in one sitting will very often simply talk to whoever responds first — not because that vendor is necessarily the best fit, but because the conversation starts there and momentum tends to stay with it. Being first is a genuinely powerful, somewhat blunt advantage that most sales processes don't organize around nearly as tightly as the data suggests they should.
