Direct access to me and my developers

I'm Sam Halcrow. I step in as fractional CTO on every project. You'll deal directly with me and with the developers working on your software.

We agree on the goal before we start

Before my developers begin, we agree on what the software needs to fix, like hours lost to manual data entry. We measure the project against that goal.

A CTO's judgment on every project

I've spent 16 years making tech calls. I'll tell you which parts of your process are worth building software around and which are fine as they are.

Sometimes an off-the-shelf product with a few changes will do the job for less. If that's the case, I'll tell you before you commit to a custom build.
