Challenge

Small businesses were drowning in disconnected tools — payroll in one place, accounting in another, banking scattered across platforms. OneCo needed a unified solution that actually worked.

The vision was ambitious: build the world's first truly unified business platform. But translating that vision into reality meant solving complex integrations across banking, payroll, accounting, HR, and compliance — all in one seamless experience. The stakes were high: small businesses needed this to work flawlessly from day one, and investors needed proof of concept fast. 'We had the idea,' Michael said, 'but we needed a team who could turn complexity into simplicity.'

The team didn't just code — they became our technical co-founders. Every decision was made with our users in mind.

Solution

We built an all-in-one platform that doesn't feel like one — intuitive, fast, and built to scale.

We started with the core: smart business banking with automated dispersion, integrated payroll with next-day direct deposit, and AI-powered bookkeeping that actually understands small business workflows. Using Next.js for a lightning-fast frontend and Node.js with PostgreSQL for robust backend operations, we created a system where everything talks to each other — no manual data entry, no reconciliation headaches. We integrated with Plaid for banking, Stripe for payments, and built custom APIs for payroll tax automation across federal, state, and local jurisdictions. The platform went from concept to beta in 12 weeks, with zero critical bugs at launch.

Results

From scattered tools to unified platform — small businesses now run everything from one place.

OneCo launched with over 300 businesses in the beta program. Payroll processing time dropped from hours to minutes. Businesses reported 70% less time spent on back-office tasks. The platform now processes millions in transactions monthly with 99.9% uptime. 'You didn't just build a product,' Michael told us. 'You built the foundation of a company that's changing how small businesses operate.'
