Big announcement from Supertop’s blog today:

We have some news to share. Tiny has purchased a majority stake in Castro. We are still shareholders and will continue working on the app full time.

The post goes on to explain the reasons for this transfer of ownership.

Castro has reached a size where the demands of running the business have been pulling us in too many different directions. We haven’t been able to focus as much on the core work of designing and building a product. Selling to Tiny gets Castro access to more resources, contacts and expertise. By growing the team we can specialize our roles to be more focused individually and get more done collectively. We can get back to what we’re good at and what we love doing.

Castro underwent a business model transition earlier this year, moving from paid up front with Castro 2 to free with Castro 3 alongside the launch of the Castro Plus subscription option. It sounds like that shift has led to an increased amount of administrative work for Supertop’s development team, which should be alleviated thanks to this acquisition. The post concludes:

We’ve started work on Castro 4. The plan is to improve the design to bring more listeners into the Castro flow. We’re excited, because for the first time in five years of work on Castro, we’ll have the resources to focus exclusively on it as product designers and developers, without contract work to distract us, and with a team around us to handle the administrative tasks.

Castro is one of the best podcast clients on iOS, so I’m thankful that today’s announcement doesn’t spell its end. On the contrary, it sounds like there’s reason to be hopeful about the app’s future in Tiny’s hands. Only time will tell, of course, so I’ll be curious to watch the app’s update cycle over the coming year.
