When I worked for Procter and Gamble every season brought a new flock of new and improved geese. My favorite P&G story is when the founders of the company made a mistake and included too much air in their soap making it float they flip negative to positive claiming, "It's so pure it floats," and Ivory soap was born.
HubSpot did much the same thing. They took an old set of tools and, reading the content marketing tea leaves Google has been asking all to drink for a long time, they created the concept of "inbound marketing" where your content is your outbound call center.
Brilliant pivot. HubSpot generated $29M last year and took in $62M in VC, so life is good in the land of the pivot surving the monster content marketing wave. I like HubSpot, but it is no magic bullet. I would trade the money I would pay them for 5 really hot writers because viral content creats its own destiny.
And here's the rub. Not just ANYONE can create viral content. Expect even the hottest viral content creator to bat about like a home run hitter so 3 out of 10 is great, 4 out of 10 is Hall of Fame and 5 out of 10 consistently is impossible since odds are with the house (Google).
