MVP Development
Your MVP, live in 2 to 6 weeks.
We deliver a first version your customers can use. We settle the scope with you, place a working prototype in your hands within days, and build from it. Most MVPs go live in 2 to 6 weeks.
First version · 2 to 6 weeks01 · Why build your MVP with WeaveLines
Every first version we ship has four things in common.
Live in 2 to 6 weeks
We scope the first version with you, prototype it in days, and ship a working product in 2 to 6 weeks. When the scope is tight, two weeks is enough.

A scope you can defend
The first version holds what a customer needs to get value and what an investor needs to see. Everything else goes on a list with a reason, so the decision remains yours and is written down.

A prototype before code
Within days you have a working prototype with real screens, real flows and the states a demo usually skips, ready to use, show to customers and put in front of investors. A designer directs it and validates it with you, and engineers build from it.

Built in the stack it will grow in
The MVP is real software rather than a demonstration to be discarded later. Most often that is TypeScript, with React on the web, React Native with Expo on mobile and Node.js behind them, and when a product calls for something else we use that instead. When the product grows, the code grows with it.

03 · The MVP process
From a conversation to a product in your customers’ hands.
Shape
Days
You receive a backlog for the first version and a plan with a date on it
A few working sessions settle the goal, the users and the scope. AI-assisted research brings the market, the competitors and the first personas to the table, and you bring what you know about your customers.
Prototype
Days
A prototype you can put in front of customers and investors, close to the product that will ship.
A designer directs a working prototype with AI design tools, and we shape it with you in short rounds until it is as close as we can get it to the product that will ship. Changes at this stage are quick and inexpensive, so this is where the scope is settled.
Build
2 to 6 weeks
You receive working software to review at every step
Engineers build from the validated prototype in the real stack, and the designer stays with the build, so the design keeps improving until it ships. Engineers use AI coding tools daily, automated tests and CI run before anything ships, and a second engineer reviews the changes that carry risk.
Most often
- TypeScript
- React
- React Native
- Expo
- Node.js
- PostgreSQL
Launch
Days
Live 2 to 6 weeks after kickoff
The product launches in the app stores or on the web, with monitoring and error tracking in place before the first user arrives.
Most often
- AWS
- Cloudflare
- EAS
- App Store
- Google Play
Learn and grow
After launch
Ongoing, on a monthly retainer
The first weeks of real usage decide what comes next. We remain engaged for fixes, improvements and the next features, or take the fractional CTO or CPO seat when that is what you need.
What moves the timeline
The promise is for a focused first version, from the day the scope is agreed. Two things move it.
Where you start
- An idea
- Discovery and a prototype come first. Days, not weeks.
- A validated prototype
- Straight to the build.
- An existing product
- A short review of the code and the release setup, then a plan.
What you are building
- A focused MVP
- Live in 2 to 6 weeks, and in 2 when the scope is tight.
- A larger product
- Several applications, payments or identity, a regulated market. We tell you what it takes after discovery, before work starts.
04 · What we build with
The stack is chosen for each product.
These are the technologies we work with most.
Web
TypeScript and the React ecosystem, with the framework chosen per project.
Mobile
React Native with Expo, for iOS and Android.
Backend
Node.js, with PostgreSQL first and MongoDB, Neo4j or Redis when the data has a different shape.
Cloud
AWS first, Cloudflare where it fits, and a plain server when that is the right size.
AI features
Claude, GPT, Gemini or open models, chosen per use case.
05 · How we engage
A fixed price, agreed before we start.
Most MVPs are delivered as a fixed-price project with an agreed scope, an agreed price and a launch date. When the scope is still moving, time and materials billed monthly fits better, and we will say so before work begins. After launch, a monthly retainer keeps the product moving.
All four ways to engage06 · Frequently asked questions
What founders ask about an MVP.
How long does an MVP take?
Most products take 2 to 6 weeks, and 2 when the scope is tight. What moves the number is how many flows the first version needs, whether it ships on the web or in the app stores, and how quickly decisions are made on your side. We agree the scope and the plan with you before work begins, and you review working software regularly as it takes shape. A product that is more than a first version takes longer: several applications, a model of its own, a regulated market. We tell you which yours is, and what it takes, before work starts.
What is included in an MVP project?
An MVP project covers everything between the idea and a product in your customers’ hands. That includes discovery and scope, the working prototype, the design refined through the build, engineering, testing, and launch on the web or in the app stores. Design and engineering happen in the same place, so there is no handoff between a design agency and a development shop.
How do you decide what goes into the first version?
Together, and in writing. We start from what a customer needs to get value from the product and what an investor needs to see, then set aside everything that does not serve one of those two. Every feature that is cut goes on a list with the reason, so nothing is lost and the decision remains yours. AI-assisted research accelerates the market and competitor side of that work, and the decisions are made by people.
Is design included, or do I need a separate designer?
Design is included. Research, the working prototype and the interface it becomes are part of the project, with design running alongside engineering so it does not add weeks. Brand identity is included when the product needs its own. If you already have a brand or a designer, we work with them.
What technology do you use for an MVP?
We build in the stack the product will grow in, so nothing has to be rebuilt later. Most often that means TypeScript, the React ecosystem on the web, React Native with Expo on mobile, Node.js behind them, PostgreSQL first, with MongoDB, Neo4j or Redis when the data has a different shape, and AWS first, Cloudflare where it fits, and a plain server when that is the right size. For AI features, we use Claude, GPT, Gemini or open models, chosen per use case. When a product calls for something else, we use that instead and tell you why.
What happens after the MVP launches?
Launch is where the learning begins. Monitoring and error tracking are in place before the first user, and the first weeks of real usage decide what gets built next. Most clients keep us on a monthly retainer for fixes, improvements and the next features, and some ask us to take the fractional CTO or CPO seat.
How is an MVP priced?
Most MVPs are delivered as a fixed-price project with an agreed scope, an agreed price and a launch date, so you know the number before work begins. When the scope is still moving, time and materials billed monthly fits better, and we will say so up front. We provide a quotation after a short call about what you are building.
I already have a prototype or a half-built product. Can you take it from there?
Yes. Some clients arrive with a prototype, and some with a product another team started. We begin with a focused review of what exists, keeps what holds up, and plans the shortest route from there to a launched first version.

How we prototype with AI tools, from a brief to an interactive prototype in days
The first thing a client sees from WeaveLines is a high-fidelity interactive prototype, in days. How a brief becomes screens with Claude Design, Figma Make and Replit, what the designer decides, what we validate with you, and what happens next.
What vibe coding is genuinely good for and why it does not survive real users
Vibe coding produces a working demo in an afternoon, and that is real. It also produces code nobody has read, with security flaws in about half of it, and it breaks the moment real users arrive. This article draws the line, presents the evidence, and sets out what to do instead.
Fixed price or time and materials, and how to choose the engagement model for your product
Fixed price gives you a number before work starts. Time and materials gives you room to change your mind. Which one fits your product depends on how well the scope is known. This article covers how to choose, what to write into the contract, and when to switch.
