Its engineers build and operate cloud infrastructure, data platforms, software and cybersecurity systems inside classified environments, with a particular concentration in Amazon Web Services work for the intelligence community. Headquartered in Columbia, Maryland with offices in northern Virginia, it employs cleared staff almost exclusively, which is both the barrier to entry in its market and the constraint on how quickly it can grow.
