Software studio, brewed slow, made to fit not generated

we're techpotions, a small software studio. we build custom web apps, AI products and mobile apps for founders who care about craft. made to fit, not generated. most software is bought off the shelf and bent to fit. we do the opposite. we start from what you're actually building, shape it from scratch, and ship something production-grade from week one. not demos, not templates. what we make: custom web apps, AI products, mobile apps. all of it built to fit the work in front of you. who we're for: founders and small teams who'd rather have software that fits than software that's fast to set up and slow to love. big ideas, brewed slow. tell us what you're building. we'll reply within 24h.
