Whether the rapid growth rises from fresh rounds of funding, the signing of multiple big clients or expanded sales (and sometimes, all three), the swelling business leads to exciting news: your staff needs to double from 100 to 200 people fast. The challenge: your office cannot accommodate that many people, so it’s time to find a new space. Punitive, complex leases. Terms that lock you into space for at least five years. Landlords who seem to find pleasure in lawsuits. Time-devouring tours of far-flung spaces, working closely with designers to ensure space matches your culture, getting the IT right. The oppressive to-do list goes on and on.
