Our thesis
Why founders choose Northstar
"Northstar wired the first check within ten days of our first call. Three years later they're still the partner I text at midnight before a hard board decision."
"They understood our infrastructure thesis better than we did at the seed. Northstar doesn't chase hype — they have real conviction and the patience to match it."
"When the market turned, our growth investors went quiet. Northstar leaned in, helped us cut the right things, and bridged us to a round that valued us higher."
