Startup MVP Package
Strategy, design, and a tight first feature set, scoped to what you need to launch.
Talk about an MVPUI/UX Design
User flows and wireframes, then high-fidelity screens in Figma. You approve the UI before we write the interface code.
E-commerce & Shopify
Custom storefronts, theme work, and checkout flows on Shopify.
Technical Guidance
Architecture reviews, codebase audits, and a written read on where the product stands.
From Idea to Launch
A four-step process from the first call to a live product: discovery, a written proposal, the build, then store submission and handoff.
Discovery Call
A conversation about the product, the constraints, and whether the work is a fit.
Proposal & Design
A written scope, timeline, and fixed price. Then we move into Figma and lock the screens.
Build & Iterate
Two-week sprints. You get a working build at the end of each one, and feedback goes into the next sprint.
Launch & Support
App Store and Play submission, a handoff of the repo and accounts, and optional maintenance after you launch.
The BitBridge ApproachWork with the person
Work with the person
writing the code.
You work with the person who designs the product and writes the code. Questions, weekly demos, and scope changes all go through that same thread, from the first sketch through launch.
We take on architecture and the build itself, and you stay in that conversation for the life of the project.
Direct access
You message the developer on Slack or email. That is the working channel for the project.
Based in Tampa
The shop is in Tampa, Florida. We work with clients in other cities and time zones.
Full ownership
After final payment, you own the code, the intellectual property, and the store or cloud accounts.
What Clients Say
“BitBridge's consulting helped us rethink our architecture. They were strong on mobile development and cloud integrations, and that saved us months of trial and error. I would recommend them if you need senior guidance.”
“BitBridge built a custom web application for my business. The attention to detail was good, communication was clear throughout, and the final product has made day-to-day operations easier.”
Frequently Asked Questions
Pricing depends on the scope. After a discovery call we send a fixed-price proposal that covers the features, the timeline, and what is in the first release. The number is in that proposal, once the scope is written down.
You do. After final payment, the source code, design files, and intellectual property transfer to you, along with the developer accounts we set up for the project.
No. The lead engineer designs the product and writes the code. You work with that same person for the life of the project, on Slack and on the weekly demos.
Flutter is a good fit for a lot of products because one codebase can ship to both iOS and Android, which usually means a shorter timeline and a lower cost. Swift and Kotlin are the better match when you need camera control, Bluetooth, background processing, or other work that sits close to the OS. We talk through that tradeoff on the discovery call and pick a stack from there.
Yes. We set up the developer accounts, prepare the store listings and screenshots, submit to both the App Store and Google Play, and handle the review back-and-forth until the app is live.
We start with discovery and wireframes to map the user flows, then move to high-fidelity mockups in Figma. You review and approve the screens before we write the UI code. Changes after that go through the sprint process.
The MVP track covers product strategy, UI/UX design, development of a tightly scoped first feature set, and deployment to the App Store or the web. It is for getting a first version in front of users. Later features can be a second phase once you have that feedback.
We set up a dedicated Slack or Teams channel for the project. You talk to the lead engineer there, and we send weekly progress updates with a demo you can click through.
We offer maintenance if you want it: OS updates, security patches, and small fixes as the stores and operating systems move. We can also help you hire and onboard an internal team to take the product over.
Yes. We will sign a Non-Disclosure Agreement before you share anything confidential about the idea or the business.
