My current job has zero planning meetings and a standup twice a week with 20 people attending that lasts about 7 minutes on average; standup is literally "what are you working on and are you blocked?". If the person rambles in standup, our boss cuts them off and has the next person go. It's been this way for at least a year and a half (when I started). We're given wire-frames or high-level designs of what needs to be built and the target goal date. Developers are then left to code with nearly full autonomy. We always deliver the product early. I've worked in so very many places over the last decade and a half - from huge corporations to small startups - and if all of them took this approach, they would've increased their productivity at least 10-fold.
We had a product manager who would regularly play our builds and speak with the clients. If the clients were unhappy, had feedback, or found bugs, he would chat or hop on a call with the lead developer (usually me). We’d write it on a sticky note or put it in our mind palace as a Todo (or if you were a defensive programmer and planned that a certain piece of code needs to be flexible, you were fixing it while he was explaining the problem).
So, we had communication, but not in the form of formal meetings. Product set the delivery dates, we set goals/cadence as engineers around those dates, and based off of continual feedback we iterated on the design.
Daily scrum and weekly grooming and quarterly planning. That’s for product. That’s counting beans and making sure no one goes rogue and accidentally innovates.
Daily scrum is nothing more than a product status meeting. If you’re a dev and you’re waiting for that meeting everyday to tell someone you’re blocked or need something.. then there’s a communication problem.
These apps also include ad sales to the IAPs. The money no longer needs to come from the initial download.
Zynga was one of our biggest clients. Hasbro came in second. As well as a few white label advergames (eg. Vans shoes). We rarely made more than a small cut on profits (if that) and were generally paid upfront and on delivery.
