start-up ecosystems need cold frames as well as green houses

Anyone involved in anyway in the world of start-ups and business growth will be familiar with the range of support models there are out there that make up the 'eco systems' of incubators, accelerators, investor networks, and such like.

And there are good arguments that we need a mix of different supports and types of models because no two start-ups are exactly alike, and different founders and entrepreneurs will respond better to different interventions at different times.

But it struck me recently when I was speaking with a programme manager for a foundation that is seeking to do more to encourage disruptive start-ups (yes Sam, that is you I'm talking about!), that there may be a missing link in all these ecosystems that entrepreneurs and founders can apply to - to use a gardening analogy: there's a lot of 'hot housing' going on out there already (things that help the seeds of a start-up sprout and start to grow more quickly than they would if we'd dropped the seed packet into a flower bed next to the lawn and hoped for the best); but any gardener will attest to this hot housing only being half of what's needed to ensure new plants thrive in the future. 

That's because hot houses are not the norm of the world - our gardens aren't covered and heated to higher temperatures than the British weather usually offers us all year round, so when we move these exciting new plants from their 'bubble' of an ideal world into the real world, it can be something of a shock... Which is why good gardeners will always have a cold frame lurking somewhere - a place that these specially nurtured new plants can best acclimatise, transition, and ultimately get used to the suddenly harder and harsher world that exists outside the hot house that they grew up in and came to rely on.

For our wider start-up ecosystems, where are these cold frames? 

The closest I can think of would be the peer networks amongst founders that they create informally by virtue of having shared the same hot house, but what else might be able to be offered by way of regular check-in, a phased 'moving on' from the hot house facility, and such like? 

Because if we don't have a way to move start-ups out of the hot house in ways that help best assure them on their future survival and success, then they'll get too comfortable, and take up space that other start-ups need if they're to have their opportunity to make it themselves as well?
