    From Side Project to a SaaS With Paying Customers

    Designed, built, launched, and operate a SaaS product solo, taking it from zero to paying customers with no marketing budget.

    The Challenge

    Small businesses drowning in manual admin: chasing invoices, copying data between tools, following up on unpaid quotes. The existing tools were either too complex, too expensive, or not designed for how SMBs actually work. I wanted to build something lean, focused, and genuinely useful, and prove I could take a product from idea to revenue entirely on my own.

    The Approach

    I built RevoBill end-to-end: product design, engineering, infrastructure, marketing, customer support, and GTM. All solo. The product automates the full quote-to-invoice-to-payment flow for SMBs, removing the manual steps that cost small business owners time they don't have. I treated every aspect, including support conversations and onboarding, as a product signal, iterating fast based on what real users told me.

    The Outcome

    RevoBill has paying customers, acquired with zero marketing budget through product quality and word of mouth alone. It's a live, operating SaaS business that I continue to build and scale. More than the metrics, it's proof that I can operate at every layer of a product: from the first line of code to the first paying customer.

    This kind of work usually runs as fractional CPO.
