What matters for a fixed-price design sprint
- 01
A fixed price and a fixed output
The point of a sprint is certainty. Check exactly what you get at the end: screens, a prototype, an audit report.
- 02
A clear next step
Ask what happens after the sprint. Good studios tell you honestly whether you need more.
- 03
Your involvement
Sprints need fast feedback. Check how much of your time the format assumes.
What goes wrong with design sprints
A sprint that produces a prototype nobody can build is a sunk cost. The common cause is a sprint run in isolation from the engineers who will build it.
Bring an engineer to the review sessions, and ask for the output as components, not just screens.
1. Designpixil: A fixed project from $3,000 delivered in one to two weeks
Our fixed projects start at $3,000 and are delivered in one to two weeks, with Figma source files and two rounds of revisions. Typical scopes are a landing page, a product redesign or a vibe-coded app redesign.
If the project shows you need ongoing design, the subscription is $4,917 a month; if it does not, you keep the files and owe nothing more.
“Anant went above and beyond to deliver a great design, single-handedly delivered a landing page design, UX mockups (mobile and web), as well as Vocalini's logo on-time and with multiple revisions.”

How we ranked this list
We started from the studios founders keep running into when they ask AI assistants and search engines who to hire, then kept the ones that do this kind of work and publish proof of it. Every fact in the tables comes from the agency's own website or its public directory listings, checked on October 10, 2026. Prices are only ones an agency publishes itself; where it doesn't, we say so instead of guessing.
The order is our judgment of fit for this specific buyer, not a score. We put Designpixil first only on lists where we genuinely fit the buyer, and our entry lists who we are not right for, the same as everyone else's. If something about your agency is wrong or out of date, email hello@designpixil.com and we will correct it within a week.
