THE GOING INDIE PODCAST

Building a Business on Swift on the Server, Vapor & Open Source - Tim Condon

In this episode of the Going Indie Podcast, I chat with Tim Condon, an influential figure in the Swift on the server community and creator of Broken Hands. Besides always wearing shorts and having the perfect podcast voice, Tim's journey is also inspiring.

We explore Tim's journey to becoming an independent developer, managing multiple projects like Vapor, and organizing the Server Side Swift Conference. Tim shares valuable insights on hiring employees, creating a sustainable business, and maintaining a healthy work-life balance.

The conversation also covers Tim's experience speaking at conferences, building a personal brand, and navigating the initial challenges of going indie. This episode offers plenty of practical advice and inspiration for aspiring indie developers.

QUESTION OF THE WEEK

How did you do in Q1 2025?

This week, I'd like to reflect on the first quarter of 2025. I want to show you how I've been doing and give you an idea of how I approach planning and goals.

At each start of the quarter, I sit down and reflect. Did I reach what I hoped to achieve? What were the actual results? What could I have done better? And finally—did something go differently than expected?

The answers to these questions are super powerful and ensure I'm constantly working on the things that matter most. I have a specific goal for the year, which I use to populate smaller goals per quarter (I explain a lot of this in my Going Indie course)

For Q1, I focused on growing RocketSim MRR, RocketSim for Teams ARR, SwiftLee Weekly subscribers growth, SwiftLee articles quality, and Course income. A few conclusions:

  • RocketSim MRR growth faster than expected (reached 113% of my goal)
  • SwiftLee Weekly & SwiftLee blog visitor count reached 80% of the goal. The ideal outcome for stretchy goals
  • RocketSim for Teams (378%) & Courses (370%), however, performed way better than expected

I'm satisfied with the results, but I should've been way better at setting goals for the latter. I didn't expect to release my concurrency course, so that's explained easily. RocketSim for Teams, however, performed way better than we could've hoped for!

The results influence the overall yearly goal. I like to revisit goals and optimize per quarter, even though some prefer not to touch an annual goal. I push myself to reach even higher results by stretching a goal with a higher target.

Most important of all, though, is reflection. Reflecting on a quarter is the fundamental part of this story. If you're unable to reflect, it becomes harder to indicate performance and potential improvements. Q2 just started, so I encourage you to sit down and put yourself up for success by aiming for specific targets. Good luck!
