Inventiple builds startup MVPs for funded founders who need real, scalable products — not throwaway prototypes or slide-deck demos. Every line of code is written or reviewed by a senior engineer averaging 10+ years of production experience. We deliver in 8 weeks what most agencies take 4–6 months to ship.
You've raised pre-seed or seed funding. You have 12–18 months of runway, a sharp product hypothesis, and pressure from investors to ship something real before the market moves. So you go looking for a development partner — and almost every option fails startups in a predictable way.
Traditional agencies quote 4–6 months and pad the team with juniors. You pay senior rates for engineers who've never shipped a production SaaS product. The architecture they pick won't survive your first 1,000 users, let alone 100,000. Six months in, you're rewriting their work instead of talking to customers.
No-code and low-code tools create demo-ware, not products. Bubble, Webflow, and Retool are fine for validating a hypothesis in a weekend. They are not fine for a product that needs custom business logic, real authentication, payment processing, or an architecture your next engineering hire can extend. Founders who start on no-code almost always pay twice — once for the prototype, once for the rebuild.
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 before a demo day, 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 margin needs — not yours. The MVP ships late, over budget, and missing the features that actually matter.
Scope creep kills more MVPs than bad engineering. Founders arrive with a 40-feature roadmap and a 12-week budget. Agencies say yes to everything because it inflates the invoice. Eight weeks in, half the features are half-built, nothing works end-to-end, and the launch date has slipped twice. The MVP that ships is neither minimal nor viable — it's a demo that embarrasses you in front of investors.
The result for most founders: 6 months gone, $150K spent, a product that either doesn't work or is architecturally a dead end. We've inherited dozens of these rebuilds. We exist because the default model is broken for funded startups that need to move fast without cutting corners on engineering quality.
Inventiple is structured around a single conviction: a small team of senior engineers, equipped with modern development tooling, ships faster and better than a large team of mid-level developers. Everything about our process follows from that.
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 through launch.
The hardest part of MVP development isn't writing code — it's deciding what not to build. We run ruthless scope sessions in week zero and tell you what to cut, and why. A focused MVP with one excellent core workflow beats a kitchen-sink v1 with fifteen half-built features. Our job is to get you in front of real users fast, not to build everything on your roadmap.
Week one is architecture: data model, API surface, auth model, deployment infrastructure, and observability. We deliver a written architecture doc you can show to your CTO, your investors, or your first engineering hire. 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. Authentication is real, not a hardcoded password. The database schema supports multi-tenancy from day one. CI/CD runs on every push. Your first engineering hire should open the codebase and think “this is solid,” not “we need to rewrite this.”
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.
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.
Here's exactly how a standard startup MVP engagement runs. We adjust based on scope, but this is the backbone. The numbers in parentheses are typical hours of senior engineering effort.
Two to three working sessions, usually over one calendar week. Output: a written scope document, a fixed-price quote, user journey maps, and an architecture sketch. You're free to walk away here at no cost. (10–15 hours)
Data model, auth, multi-tenancy, deployment infrastructure, observability, repo setup, CI/CD, and design system foundations. End of week: working dev environment, deployable skeleton, and architecture doc signed off. (60–80 hours)
Application APIs, business logic, database layer, and the primary user workflows. This is the boring-but-critical layer that makes everything else possible. End of week 3: usable internal product with core features working, no UI polish yet. (140–180 hours)
Secondary features, third-party integrations (Stripe, CRM, email), admin dashboard, and any optional AI features. Payment flows, transactional emails, and onboarding sequences get built here. End of week 5: feature-complete product. (120–160 hours)
Final design pass, micro-interactions, mobile responsiveness, empty states, error handling, and accessibility basics. End of week: product that looks and feels production-ready. (60–80 hours)
End-to-end testing, cross-browser QA, load testing, security review, monitoring setup, alerting, and runbook documentation. We deliberately allocate a full week to this because most agencies skip it. (50–70 hours)
Production deploy, DNS cutover, monitoring live, analytics configured, documentation review, and knowledge transfer to your team. 30 days of free post-launch support included. (30–40 hours)
Most agencies hide their pricing behind a discovery call. We don't. Here's what a startup MVP from Inventiple actually costs in 2026. For AI-heavy products, see our AI MVP development page and cost breakdown.
Single core workflow, basic auth, web-only, one integration.
Multi-feature SaaS, real users from day one, 2–3 integrations.
Mobile apps, compliance (HIPAA/SOC 2), AI features, or enterprise SSO.
Payment terms: 40% on kickoff, 30% at mid-engagement demo, 30% on production launch. We invoice in USD, EUR, or GBP. See our SaaS cost guide for broader product budgeting context. Most founders pair an MVP build with cloud-native infrastructure when they expect rapid user growth after launch.
We pick boring, proven technology for the layers that need to be reliable, and modern tooling for the layers where developer velocity matters. Your MVP should be something your first engineering hire recognizes and can extend — not a custom framework they've never seen.
Every stack choice is documented in the architecture doc with rationale. If you have strong preferences (e.g., Django over Node, or Supabase over raw RDS), we'll accommodate them when they don't compromise scalability. Our default stack reflects what we've shipped most often for funded SaaS startups in 2025–2026.
Startup MVP development is a fit decision, not just a budget decision. The founders who get the most value from our engagements share a few traits — and the ones who struggle usually know it before we tell them.
A typical 8-week startup MVP from Inventiple ranges from $40,000 to $70,000 fixed price. Lean MVPs with a single core workflow and web-only delivery start at $40,000–$55,000. Standard MVPs with multi-tenant architecture, payments, and 2–3 integrations range from $55,000 to $80,000. Complex MVPs with mobile apps, compliance requirements, or multiple AI features range from $80,000 to $120,000. US agencies typically quote $120,000–$250,000 for comparable scope over 4–6 months.
A well-scoped startup MVP takes 6–8 weeks with a senior engineering pod. Lean MVPs with a single core feature can ship in 4–6 weeks. Complex builds with native mobile apps, enterprise integrations, or compliance scaffolding need 10–12 weeks. Timelines slip when scope isn't locked before kickoff or when founders add major features mid-build — which is why we invest heavily in week-zero discovery.
Every engagement includes: product discovery and scope lock-in, architecture documentation, full-stack engineering (front end, back end, database), authentication and multi-tenancy, production deployment on your cloud account, CI/CD pipeline, monitoring and error tracking, weekly live demos, and 30 days of post-launch support. You own 100% of the code, infrastructure, and IP from day one.
We primarily build web-first MVPs using Next.js and React — responsive across desktop and mobile browsers. For native iOS and Android apps, we typically recommend shipping a polished web MVP first, then adding React Native or Flutter in v1.1 once you've validated demand. Native apps add 4–6 weeks and $25,000–$40,000 to the timeline and budget because of App Store review cycles and platform-specific work.
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 rotate team members mid-project. Every commit is authored or reviewed by a senior engineer. You meet your team in discovery and they ship your product through launch.
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 lives in your GitHub or GitLab organization. We're contractors building your asset — not a SaaS platform holding your product hostage.
Yes. About 40% of our startup MVPs include at least one AI feature — a RAG-powered knowledge base, an AI copilot, intelligent search, or workflow automation. AI features add $10,000–$30,000 depending on complexity. If AI is core to your product hypothesis, see our dedicated AI MVP development service for a deeper breakdown of agentic and LLM-powered builds.
Three options. (1) You take it in-house — we hand off complete documentation, runbooks, and 30 days of free post-launch support. (2) You retain us on a monthly engineering retainer for continued feature work. (3) Hybrid — we stay on for a 90-day post-launch phase while you hire your first engineers. About half our MVP clients move to option 2 or 3 because shipping speed matters in the first 6 months after launch.
Yes — pre-seed through Series A is our sweet spot. We work with founders who have raised $250K+ and can allocate $40K+ to product development. We don't do equity-only arrangements or free spec work, but we do offer a free 45-minute architecture review before any commitment so you can validate fit and budget before signing.
Yes. Roughly 30% of our engagements start from an existing prototype — a no-code build, a hackathon project, or code from a previous agency that doesn't scale. We start with a one-week paid technical audit to assess what's salvageable, then quote a rebuild or refactor scope. It's almost always faster and cheaper than starting from scratch when the prototype validates the core idea.
