Production-grade code you own, ready to scale or pivot after launch.

01

How we scope what to cut

Most MVPs fail by being too big, not too small. As an MVP development company for startups, our first job is to find the one assumption that must be true for your business to work, and design the smallest product that tests it with real users. Everything else goes on a later list, written down, so nothing is lost and nothing sneaks back in.

In scoping we map the core user journey end to end, mark each step as must-have, fake-it-for-now or later, and decide what can run manually behind the scenes. A spreadsheet, a human reviewer or an off-the-shelf tool often replaces a lot of custom code in the first version.

  • One core journey, built properly end to end
  • Manual operations behind the scenes where they save build time
  • Off-the-shelf auth, payments and email instead of custom builds
  • Analytics on the actions that prove or disprove the idea
02

AI MVP development

AI MVP development has its own trap: a demo that looks great on ten examples and falls apart on the hundredth. We build a small evaluation set from realistic inputs early, so you can see accuracy, failure cases, latency and cost per task before you put the product in front of customers or investors.

We usually start with hosted models such as GPT, Claude or Gemini because they are the fastest way to learn, and design the integration so you can switch providers or move to open-weight models later. Where answers must come from your data, we use retrieval with citations so users can check the source for themselves.

We hold our own products to the same standard. The M361 AI Writing Studio, which turns a brief into a draft in a brand's voice, shows a live brief-quality score and transparent per-article AI cost, so quality and spend sit side by side. AI MVPs we build for founders get the same visibility from the first release.

  • Evaluation set built from realistic inputs, not cherry-picked demos
  • Cost and latency per task measured before launch
  • Swappable model providers behind your own API
  • Human review for outputs that carry real risk
03

MVP app development for mobile and web

Many MVPs should start on the web: faster to ship, easy to change daily and no store review. Our MVP app development covers both. We build web MVPs with Next.js and React, and mobile MVPs with Flutter or React Native when the idea depends on the phone itself, such as push notifications, the camera, location or offline use.

Either way, the back end is built so a second platform can be added without a rewrite. The data model, APIs and auth are shared, and the code is typed and tested on the paths that matter, so the MVP becomes the foundation of version two rather than something you throw away.

04

MVP development cost and timeline: what drives them

We don't quote before scoping, because MVP development cost depends on choices you control. The biggest drivers are the number of user roles, the integrations you need on day one, whether AI features need custom evaluation, mobile versus web, and how much polish the first release needs to win trust with your buyers.

After the scoping call we break the build into milestones, such as design, a first working version and launch, and fix the price of each before work starts. Timeline follows the same drivers and is confirmed in the proposal. If budget is tight, we cut scope rather than quality, and show you which cuts change the test and which don't.

  • User roles and permissions
  • Day-one integrations: payments, CRM, messaging, data sources
  • AI features and the evaluation they need
  • Web, mobile or both
  • Design polish your buyers expect
05

After the MVP: scale or pivot

An MVP is a question, and launch is when the answers start arriving. We set up product analytics and feedback loops before launch, so your first real users tell you whether the core journey works. If it does, we harden the product: performance, monitoring, security reviews, multi-tenancy and billing. If it doesn't, the codebase is modular enough to pivot without starting over.

Many founders keep going with the same people through a milestone-based product build or a dedicated AI pod on a monthly retainer. Either way, our MVP development services leave you owning 100% of the code and IP, so you can take the product in-house whenever you are ready.

FAQ

Questions, answered.

How long does it take to build an MVP?

It depends on the drivers that set cost: user roles, day-one integrations, AI features, and web versus mobile. A tightly scoped MVP moves much faster than a feature list, which is why we spend real effort deciding what to cut. Milestone dates are confirmed in a fixed proposal before any work starts, and you see working software in weekly demos.

How much does MVP development cost?

We don't publish fixed packages, because two MVPs with the same name can differ hugely in scope. After a free 20-minute scoping call, we split the build into milestones and fix a price for each one before work starts. If the number is higher than your budget, we show you which features to cut and what each cut changes.

Should our MVP include AI?

Only if AI is part of the value you are testing. If it is, we build it properly from the start, with an evaluation set, cost per task and fallbacks when the model is unsure. If it isn't, we leave it out of version one and design the product so AI features can be added once you know what users need.

Will we have to rebuild the MVP later?

Not if we've done our job. We cut scope, not quality. The MVP is built on a mainstream stack with typed code, tests on critical paths and infrastructure as code, so it becomes the foundation of version two. Some parts will change as you learn, which is the point, but the core should not need throwing away.

Do you work with non-technical founders?

Yes. We explain trade-offs in plain language, write decisions down, and show progress as working software rather than technical reports. You own the repositories, cloud accounts and 100% of the code and IP from the start, so you are never locked in, and a future technical co-founder or in-house team can pick up where we left off.

Can we start with an AI pilot instead of a full MVP?

Yes. If your main risk is whether AI can do the job at all, a fixed-scope, fixed-price AI pilot tests one workflow on your real data first. You get a working system, an evaluation report and a roadmap, which then becomes the starting point of a fuller MVP if the results hold up.
