Especially in the start-up phase, resources are scarce and flexibility is the top priority. A permanently rented office is rarely a good answer to rapid growth and constant expansion of the team.
The only constant is change.
Of course, having your own office for the first time is an unforgettable step on the journey of setting up a business, but the effort involved and the lack of flexibility should not be underestimated. Whether it's purchasing office furniture, contracts with the electricity provider or often long contract commitments for internet - decisions are usually quickly regretted as the business grows.
