Custom MVP development, from idea to launch
A minimum viable product is the smallest version of your product that real users can use, so you learn whether they want it before you spend on the full build. It is not a bad first product; it is a focused one. KFG turns your idea into a working MVP: we help you pick the one flow that proves the idea, design it, build it and put it in front of users.
We are a team of 60+ developers with an average of more than 10 years' coding experience. You get an estimate in 30 minutes, a clickable prototype in 48 hours and an MVP in 2 weeks for a narrow scope.
“Make something people want.” That's the fundamental problem. If your startup will die, it's probably because you didn't make something people wanted.
What we build
- SaaS web apps: sign-up, a core workflow, dashboards, subscriptions and an admin panel.
- MVP websites: a marketing site and a working product behind it, so you can launch and sell from day one.
- Mobile MVPs for iOS and Android, built after the flow is proven on the web or from the start when the product only makes sense on a phone.
- Marketplaces and on-demand apps: two sides, listings, bookings and payments.
- Internal tools and pilots that let a company test a new product with its own customers.
- API integrations with the services your product depends on, such as payments, CRMs and maps.
See past projects such as FINAPP, a financial application prototype, Gleamers, a cleaners-on-demand app, and Elite Guard Training, a basketball video training web and mobile application.
How it works
- Estimate in 30 minutes. Tell us the idea on a call. We ask about your users, the problem and your deadline, and give you a first estimate.
- Concept and scope. We help you find the unique value of the product and agree on the one core flow the MVP must deliver. Everything else goes into a ranked backlog of user stories.
- Clickable prototype in 48 hours. You get a prototype you can tap through and show to users and investors before any code is written.
- Design. Our designers turn the tested prototype into a clean interface that follows current UX practice.
- Development. We build the MVP in sprints, with a video demo every sprint so you can follow progress. A narrow-scope MVP is ready in 2 weeks.
- Launch and iterate. We launch the MVP and keep building from user feedback on your plan.
What's included
| Item | What you get |
|---|---|
| Estimate | A first estimate within 30 minutes of hearing the idea |
| Prototype | A clickable prototype of the core flow in 48 hours |
| Design | UX and UI for the screens the MVP needs |
| Development | Frontend, backend and API integrations for the core flow |
| Infrastructure | Domain, hosting and database, included in every plan |
| Progress | Regular calls and video demos; the rhythm depends on your plan |
Technology
We choose the stack that suits the product, not the other way round. Our teams work across the frontend and backend with React, Node.js, Ruby on Rails, JavaScript, PHP, AngularJS and Elixir; on Android with Java and Kotlin; and on iOS with Swift and Objective-C.
For an MVP we prefer proven services for log-in, email, payments and the database, so the time goes into the part of the product that is actually new.
Plans and pricing
MVP development runs on monthly plans, so you can change priorities every sprint and keep building after launch:
| Plan | Price | Rhythm | Best for |
|---|---|---|---|
| Bi-weekly sprints | $399/month | A call once a week, a video demo every week | SaaS of any complexity |
| Weekly sprints | $899/month | Calls twice a week, video demos twice a week | SaaS and mobile apps of any complexity |
| 24/7 development | Ask for price | Daily calls and daily video demos | SaaS and mobile apps of any complexity |
All plans include domain, hosting and database. See the pricing page for details, and our MVP development cost guide for how these plans compare with typical market prices.
Why not just use an AI app builder?
AI app builders and no-code tools are a good way to test an idea yourself, and we cover them in MVP software tools. They get harder to trust once the product handles payments, personal data or several user roles, or when it needs integrations the tool doesn't support. A development team gives you code reviewed by people, a data model built to grow, and someone accountable when something breaks. If you have already built a first version with an AI tool, bring it to the first call and we will tell you what to keep.

Frequently asked questions
How long does custom MVP development take?
A narrow-scope MVP built around one core flow takes 2 weeks, after a clickable prototype in 48 hours. Products that need several user roles, payments and multiple integrations take longer; the estimate tells you how long.
How much does it cost?
Our plans are $399/month for bi-weekly sprints and $899/month for weekly sprints; 24/7 development is priced on request. All plans include domain, hosting and database. See the pricing page.
What do I need to start?
An idea and a 30-minute call. A description of your users and the problem helps; a list of features is optional, because we will help you cut it down to the core flow.
Can you build a mobile MVP?
Yes. We build for iOS and Android, as well as web apps that work on phones. The weekly and 24/7 plans cover SaaS and mobile apps.
I already have a version built with an AI or no-code tool. Can you help?
Bring it to the first call. We will look at what you have and say what can be kept and what would need rebuilding.
What happens after the MVP launches?
You keep the same plan and the same rhythm of calls and demos, and we build the next features from user feedback.
