Sastio · App development matching
Find app developers and app designers for your idea
Sastio is how people with an app idea get matched with professional app developers and app designers. Instead of cold-emailing agencies or guessing who can build your product, you submit the idea once and we connect you with developers who may want the work.
App development, matched to you
Building a mobile app takes product sense, design, and engineering. Sastio is built for founders, operators, and anyone who needs app development help but does not already have a trusted team. Share what you want to build, your monthly budget, and how to reach you. Interested developers can then follow up.
Whether you need an app designer for the look and flow, or developers for iOS and Android, the goal is the same: the right people for this project—not a generic directory listing.
How Sastio works
- Submit your app idea. Describe the product, who it is for, and what you want built.
- Share a budget range. Developers see whether the project fits how they work.
- Get matched. We introduce you to app developers and designers who may be a fit.
- Talk and build. Interested professionals reach out so you can decide who to hire.
Who Sastio is for
- People searching for app development help for a new product
- Founders who need an app designer and engineers on one team
- Businesses that want a mobile app without hiring in-house first
- Anyone who would rather be matched than spend weeks shopping agencies
