IT used to be hard. All those C: prompts, strings... stuff no normal person could understand. No wonder they created an IT dept and stuck it in the basement.
It doesn't have to be like that. Don't create a 21st century startup with 20th century thinking.
Companies are now made up of pixels and bytes. Technology is not a department now - it has to be interwoven with everything we do. It should be intuitive for everyone - not so hard that only a specialist can handle it.
So forget about DevOps and all the other things designed to say - "this is hard, leave it to an expert". Instead focus on making it simple and easy to understand for everyone. Let someone else do the hard stuff.
This is easier than you think.
Sign up with a cloud provider - AWS, for example. Go to Bitnami, who provide one-click set up of all the programs you could ever need - CRM, ERP, Marketing Automation, Payments, Accounts - the lot. That means the only bit you need to think about is your own - the bit that makes you special.
You don't have to worry about scaling, or going global. No worries about uptime, viruses or whether you have a big enough datapipe. You don't really need a CTO - you most certainly don't need a DevOps person. It just works.
One last thing. "Sites" are twentieth century too. We now blog on Medium or Facebook, not on our own websites. We interact direct from Facebook. We navigate with Google. People stay in their social world and we have to go to them, not expect them to come to our "site".
There is a whole new generation coming through - the YouTube generation - who live on their mobiles. They don't visit websites. And there are a whole generation of companies who use datascience to hide all the complexity and deliver what people need or want, when they need or want it. The mobile is becoming the User Interface for anything and everything. It is no longer mobile first but mobile only for all but the most niche of products and services.
And it is about to get worse. Immersive technologies - virtual reality, hololens etc. will make screens a thing of the past. If you're not thinking experience, but are still thinking "site" you're stuck in the past.
Every specialist tries to build a nest for themselves in the company, full of stuff only they know how to do. Resist that temptation and - if you're the founder -stamp on it when you see it in others. Everything - technology, design, finance etc. should be part of a combined system, not a department doing its own stuff.
