You need software that runs your business and AI agents that actually do the work. These five studios deliver both without the usual agency bloat.
The New Build-or-Buy Reality
Every company is now a software company. The difference is whether you build it yourself or partner with a studio that ships. Custom software and AI agents have moved from nice-to-have to core infrastructure. You need CRM dashboards, internal automations, customer-facing apps, and marketing that scales. The studios worth knowing combine engineering depth with marketing execution. They don't just write code. They launch products, run ads, and grow revenue. That's the shift. You're not hiring a vendor. You're hiring a launch partner.
