I'm a bit late in posting, but Octopus Deploy earned a spot in the Thoughtworks Technology Radar last May:
What is the Technology Radar?
The ThoughtWorks Technology Advisory Board, a group of senior technology leaders in ThoughtWorks, creates the radar. They meet regularly to discuss the global technology strategy for ThoughtWorks and the technology trends that significantly impact our industry. The radar captures the output of the Technology Advisory Board’s discussions in a format that provides value to a wide range of stakeholders, from CIOs to developers.
Octopus was listed in the Assess category, which means:
Assess: Worth exploring with the goal of understanding how it will affect your enterprise.
Which I think is fair given how new automated deployment solutions are in the .NET ecosystem. What I found interesting is that products like Microsoft's Team Foundation Server are listed in the "Hold" category.
From the PDF:
Windows infrastructure automation should be adopted, however it still remains more difficult than automation on a Unix platform. Tools like Chef and Puppet are increasing their support, but there are also Windows specific solutions being developed like Octopus. Octopus allows automated deployment of your ASP.NET applications and Windows services and decreases dependency on PowerShell. It can be used with both NuGet using Octopak and TeamCity to create a full build, package, and deployment pipeline.
