Pros
The product is popular and well regarded with a wide reach, so if you work in the industry it could look good on your CV to be part of this journey. Strong strategic vision, but entirely owned and controlled by the founder, so only work here if you are an executor.
Cons
Despite clear strategy day to day direction and initiatives change based on the most recent podcast the founder listened to/tweet he read. There is no space for opinions or suggestions from inside the business, and employees cycle out of the business as they realise this. No trust in the workplace, just constant micro-management. A culture of 'you're only as good as your last mistake' makes this an unpleasant environment to work in where the senior people in the business care more about pleasing the founder and finding fault in others than doing a good job. Pay is ok, no process for reviewing it, so pray you have a good manager, and the company over-relies on other measures, such as Visa sponsorship, to keep the workforce in place. The sad thing is this is a feature not a bug of the management style.
