The spy network Chanakya built before he built anything else
Before Chandragupta Maurya had a throne, Chanakya had agents. The Arthashastra describes a classified intelligence apparatus, sattris (wandering monks), tikshnas (sharp agents posing as merchants), and rasadas (poison specialists who doubled as informants), deployed not during war but during peacetime. The purpose was not to react to rivals. It was to never be surprised by them. Chanakya's position was that a king who waits for a threat to become visible has already lost the advantage. The same logic applies to any business operating in a market with competitors who are not announcing their plans.
