AI MVP Development for Startups

Ship a production AI MVP in 6–8 weeks.Senior engineers only. Fixed price.

Inventiple builds AI MVPs for funded founders who need real, scalable products — not throwaway prototypes. Every line of code is written or reviewed by a senior engineer averaging 10+ years of production experience. We use Cursor, Claude, and our own internal AI workflows to deliver in 6–8 weeks what most agencies take 4–6 months to ship.

The problem with how most AI MVPs get built

You've raised pre-seed or seed funding. You have 12–18 months of runway, a sharp product hypothesis, and pressure from investors and the market to ship something real, fast. So you go looking for a development partner — and almost every option is bad in a specific way.

Traditional agencies quote 4–6 months and stuff the team with juniors. You pay senior rates for engineers who've never shipped production AI. The architecture they pick (because they don't know any better) won't survive 1,000 users, let alone 100,000. Six months in, you're rewriting their work.

Freelance marketplaces are a coordination nightmare. You spend more time managing three contractors across three time zones than building product. Quality varies wildly. Nobody owns the architecture. When something breaks at 2 AM, nobody answers.

Offshore body shops sell hours, not outcomes. You get a project manager between you and the people writing code, weekly status decks that hide problems, and a team that scales up and down based on their internal margin needs, not yours.

AI specifically makes all of this worse. In 2026, every agency claims AI expertise. Very few have shipped production agentic systems, hardened a RAG pipeline against hallucination, or architected an MCP server that integrates safely with internal data. The gap between "we know LLMs" and "we've made AI features that don't embarrass our client at scale" is enormous.

The result, for most founders: 6 months gone, $200K spent, a product that either doesn't work or is architecturally a dead end. We've inherited dozens of these. We exist because the model is broken.

How we build AI MVPs differently

Inventiple is structured around a single conviction: a small team of senior engineers, equipped with modern AI tooling, ships faster and better than a large team of mid-level developers. Everything about our process follows from that.

Senior-only engineering

Every engineer on your project has 7+ years of production experience. Our average is 10+. We deliberately don't run a junior bench. There are no handoffs to less experienced developers, no "we'll have the seniors review it later," no surprise team swaps mid-project. You meet your team in discovery and they ship your product.

AI-augmented delivery

We use Cursor, Claude Code, and our own internal agentic tooling as multipliers on senior judgment. A senior engineer with AI-augmented workflows ships roughly 3x faster than they did in 2023, with tighter code quality because the AI catches obvious classes of error before the PR opens. This is the structural reason our 6–8 week timelines are real, not aspirational.

Architecture before code

Week one is architecture: data model, API surface, agent topology, security model, observability, and deployment infrastructure. We deliver a written architecture doc you can show to your CTO or your investors. We don't start writing application code until the foundation is sound, because ripping out bad architectural choices at week six is what kills MVPs.

Fixed scope, fixed price, fixed timeline

We quote a single number for the engagement, agreed before kickoff. We don't bill hourly. We don't surprise you with change orders. If we underestimate, that's on us — we eat the cost. This forces us to be honest about scope upfront and aggressive about execution, both of which serve you.

Weekly demos, daily access

Every Friday you see a live demo of the week's work in your environment. You have direct Slack or Teams access to your engineers — not to a project manager who relays messages. The repository is in your GitHub from day one. You see every commit, every PR, every issue.

The 8-week timeline, week by week

Here's exactly how a standard AI MVP engagement runs. We adjust based on scope, but this is the backbone. The numbers in parentheses are typical hours of senior engineering effort.

Week 0

Discovery & scope lock-in

Two to three working sessions, usually over one calendar week. Output: a written scope document, a fixed-price quote, and an architecture sketch. You're free to walk away here at no cost. (10–15 hours)

Week 1

Architecture & foundation

Data model, auth, multi-tenancy, deployment infrastructure, observability, repo setup, CI/CD, and the AI infrastructure choices (LLM provider, vector DB, agent framework). End of week: working dev environment, deployable skeleton. (60–80 hours)

Weeks 2–3

Core product build

Application APIs, business logic, data ingestion, and the non-AI surface area of the product. This is the boring-but-critical layer that makes everything else possible. End of week 3: usable internal product, no UI polish yet. (140–180 hours)

Weeks 4–5

AI features

The agents, RAG pipelines, prompt engineering, evaluation harnesses, guardrails, and any MCP integrations. We build for production from day one — including observability, cost tracking, and fallback behavior when models fail. (140–180 hours)

Week 6

UI polish & integration

Final design pass, micro-interactions, mobile responsiveness, payment integration if relevant, transactional emails, onboarding flow. End of week: feature-complete product. (60–80 hours)

Week 7

QA, hardening, observability

End-to-end testing, load testing, security review, AI behavior evaluation runs, monitoring setup, alerting, runbook documentation. We deliberately allocate a full week to this because most agencies skip it and you find out in week 10 of production. (50–70 hours)

Week 8

Launch & handoff

Production deploy, DNS cutover, monitoring live, documentation review, knowledge transfer to your team. 30 days of free post-launch support included. (30–40 hours)

Pricing: real numbers, no surprises

Most agencies hide their pricing behind a discovery call. We don't. Here's what an AI MVP from Inventiple actually costs in 2026.

Lean MVP
$40,000 – $55,000
6 weeks

Single core AI feature, basic auth, web-only, one integration.

  • Senior engineering pod (2 engineers)
  • Architecture + design system
  • 1 AI feature (RAG, agent, or copilot)
  • Stripe or comparable billing
  • Production deploy on AWS/Vercel
  • 30 days of post-launch support
Standard MVP
$55,000 – $80,000
8 weeks

Multi-feature product, real users from day one, 2–3 integrations.

  • Senior engineering pod (3 engineers)
  • Multi-tenant data model
  • 2–3 AI features w/ evaluation harness
  • Admin dashboard + customer onboarding
  • Observability + cost tracking
  • 30 days of post-launch support
Complex MVP
$80,000 – $120,000

  • Penetration test + security review
  • 60 days of post-launch support

Payment terms: 40% on kickoff, 30% at mid-engagement demo, 30% on production launch. We invoice in USD, EUR, or GBP. We've never had a payment dispute in 5 years; we'd rather under-promise and ship.

What we build with

We pick boring, proven technology for the layers that need to be reliable, and aggressive new technology for the layers where capability matters more than maturity. This is intentional.

Application stack

  • Next.js 15 / React 19 with TypeScript
  • Python (FastAPI) or Node.js (NestJS) backends
  • PostgreSQL with pgvector, plus Redis for cache
  • AWS (ECS, Lambda, RDS) or Vercel + Supabase
  • Terraform for infrastructure as code
  • GitHub Actions for CI/CD

AI stack

  • OpenAI GPT-5, Anthropic Claude, open-source via vLLM
  • LangGraph, CrewAI, or custom agent orchestration
  • MCP servers for tool and data access
  • Pinecone, Weaviate, or pgvector for retrieval
  • Braintrust or LangSmith for evaluation
  • Helicone or LangFuse for observability

Who this is for — and who it isn't

A good fit if you are:

  • A funded founder (pre-seed through Series A) with $40K+ to invest in product.
  • Building an AI-powered product where the AI is core, not bolt-on.
  • Clear on the problem you're solving, even if the solution is still forming.
  • Comfortable shipping a focused v1 rather than a feature-complete v3.
  • Looking for a partner that will tell you what's a bad idea, not just build it.

Not a fit if you are:

  • Pre-funding and looking for free spec work or equity-only arrangements.
  • Looking for a $10K marketing website or a Shopify-style template build.
  • Expecting to micromanage daily standups and PR-by-PR direction.
  • Wedded to a specific tech stack we believe is wrong for the problem.
  • Unable to make product decisions within 24 hours during the engagement.

Frequently asked questions

How much does an AI MVP cost in 2026?

A typical 6–8 week AI MVP from Inventiple ranges from $40,000 to $70,000 fixed price. Complex MVPs with custom agentic workflows, multi-model orchestration, or strict compliance requirements (HIPAA, SOC 2) range from $70,000 to $120,000. For comparison, traditional dev agencies usually quote $150,000–$300,000 for the same scope over 4–6 months. Our cost calculator gives you an instant range based on your specific scope.

What can you actually ship in 8 weeks?

A production AI product with: authentication, multi-tenant data model, payment integration, a polished React or Next.js front end, AI features powered by GPT, Claude, or open-source models, a RAG pipeline if knowledge retrieval is needed, an agentic workflow if multi-step automation is needed, observability and guardrails, and deploy infrastructure on AWS, Vercel, or your cloud of choice. What we don't ship in 8 weeks: ML model training from scratch, native mobile apps requiring App Store and Play Store review cycles, or 50-feature kitchen-sink products. We're aggressive about scope, which is why we hit the timeline.

Do you build with agentic AI, MCP servers, or RAG pipelines?

Yes, all three are core to what we ship. Most of our 2026 engagements include at least one agentic component using CrewAI, LangGraph, or custom orchestration. We've shipped Model Context Protocol (MCP) servers that let LLMs access internal databases and APIs securely. RAG pipelines with vector databases (Pinecone, Weaviate, pgvector) and hybrid search are standard in any MVP that needs domain knowledge.

Who actually writes the code? Senior or junior engineers?

100% senior engineers with an average of 10+ years of production experience. We don't have a junior bench, we don't offshore handoffs, and we don't use overseas subcontractors. Every commit is authored or reviewed by a senior engineer. You meet your team on day one and they stay with the project through delivery.

What if my project needs more than 8 weeks?

If discovery surfaces scope that genuinely needs 10–12 weeks, we'll tell you upfront and quote it that way. We won't squeeze a 12-week project into an 8-week timeline. For larger, ongoing engagements, we offer dedicated senior pods on monthly retainer after the MVP ships — typical clients spend $25,000–$60,000 per month for a continued 2–4 person team.

Who owns the code and IP after delivery?

You own 100% of the code, the IP, the AWS or Vercel account, the database, the domain, and all third-party credentials from day one. The repository is in your GitHub or GitLab organization. We're contractors building your asset, not a SaaS holding your product hostage.

Where are your engineers based?

Our engineering team is distributed across Bangalore (HQ), Houston, and Frankfurt. This gives you near 24-hour development coverage and full overlap with US Eastern, UK, EU, and APAC business hours. You always have a senior engineer available during your working day.

Do you sign NDAs and work with stealth-mode startups?

Yes. Most of our funded-startup clients are in stealth or semi-stealth when we start. We sign mutual NDAs before discovery, and we've never named a client publicly without explicit written approval. Roughly 40% of our case studies remain private at the client's request.

Can you work with our existing codebase or do you only do greenfield?

Both. About 60% of our work is greenfield MVPs from a blank repo. The remaining 40% is layering AI features onto an existing product, rebuilding a brittle prototype into something production-ready, or unblocking a stuck internal team. For brownfield work we start with a one-week paid technical audit before scoping the build.

What happens after the MVP ships?

Three options. (1) You take it in-house — we hand off complete documentation, runbooks, and 30 days of free post-launch support to your team. (2) You retain us on a monthly engineering retainer for continued feature work and operations. (3) Hybrid — we stay on for a fixed 90-day post-launch phase while you hire your first engineers, then transition. About half our MVP clients move to option 2 or 3 because shipping speed matters in the first 6 months after launch.
