I was fortunate enough to travel to Moscow, as one of a handful of MassChallenge mentors, to deliver a week-long startup “bootcamp” to Russian entrepreneurs. We were hosted by the the Skolkovo Foundation, a Russian non-profit attempting to help create & commercialize advanced technologies, where its Skolkovo Innovation Center is comprised of startups across five […]


Throughout this series we’ve deconstructed the dimensions that comprise product management. Here we’ll put those back together, to see how you can employ the 3^3 framework to help you in your day-to-day endeavors. 9 modes vs. 27 types Unlike other frameworks I’ve developed, the 3^3 model is not a “matrix” in the sense that you […]


In Part 2 of this series, we explored the range of responsibilities a Product Manager can take on. Now, we’ll examine how those activities will change, based on where the product (or company), is in its lifecycle, based on the three main stages: pre-product-market-fit (pre-PMF), post-product-market-fit (PMF), or the “mature” phase. The major driver of your context […]

There are some great frameworks to evaluate the diffusion of new innovations, but these tend to be qualitative and can therefore be difficult to evaluate multiple nuanced implementations against one another. Here is a “back of the envelope” quantitative approach to assessing whether a new solution might displace an incumbent one, when competing on “convenience”. Competing on […]
