hi, i'm
whappa.
valkenburg, nl
one studio,
one pair of hands.
no team, no subcontracting, no account managers. if you work with whappa, you work directly with me. that keeps communication short, decisions fast, and costs honest.
i work with clients who know what they need and with clients still figuring it out. either way it starts with listening. what are you really trying to solve? which constraints are real, which only in your head?
alongside client work i develop my own products: cohesion for associations that want to take member administration and board continuity seriously, and stocksmith for makers who no longer want to keep their cost prices in their head.
process
four steps.
no surprises.
every engagement goes through the same four phases. you know up front what you get, when, and what it costs. with room to adjust where it gets smarter.
