The interview
Who are you and what does your company do?
I'm Matthew O'Riordan. I'm the CEO of Ably. Ably is a real-time experience platform. We provide APIs for developers to add real-time features and capabilities to their products, such as facilitating communication for fans during big sports events.
What role has Ben Miller played at Ably?
Ben's always stepped in in a sort of interim role to help us. What he's enabled us to do is just that continuity through those sorts of volatile times. It's enabled us to not have these huge gaps in the organization while we rehire, restructure and make changes.
How quickly was Ben able to integrate into the team?
Ben really stepped into an organization where we had a serious gap in the sales function initially. Within days he started to become effective, understood the business, understood our customers and could work with the team. He didn't feel like he needed to ramp.
What is Ben's communication style like with the team?
He has a very unique quality which is just a sort of radical candor that doesn't bring negativity somehow. He delivers quite strong feedback in a very constructive way. He's very direct in his approach, but it's delivered in a way that seems to be constructive and efficient.
How many times have you engaged with Miller Growth?
We've worked with Ben in three different contexts. He first came in as a salesperson and was quite effective. Then when we had a gap later, we brought him back again. I had many conversations with him about not working on an interim basis and trying to join the team fully.
