Questions we often hear
Do I own the software?
We agree on ownership and licensing upfront in your proposal, so everything is clear before we start.
Can you start small?
Yes. Many clients start with one or two modules and add more as the business grows.
Can it connect to tools I already use?
In most cases, yes — payments, email, calendars and other systems with an API.
Do you build SaaS products to sell?
Yes — from MVP to a complete subscription product, with design, development and launch strategy.
