Landing
One page, written by hand: structure, layout, responsive behaviour, launch. For a product or an event that has to be online this week.
Every build is written by hand, so the difference between the three is scope, not method. Price and timeline are fixed before the work starts, and neither moves unless the scope does.
Custom build
A site made for one task and no other: own logic, own motion, no templates. For cases where the effect has to be felt rather than described.
SaaS startup
From concept to a market-ready MVP: product strategy and scalable architecture for software meant to grow past its first release.
