We help early-stage startups build solid products without burning their runway. MVP in 3 weeks, scalable architecture, code you own.
You have an idea, a market to validate, and a limited budget. Every week counts. Every dollar counts. Traditional web agencies? They take 4 months to deliver an MVP, charge Paris-Lyon prices, and leave you with code nobody understands. Result: you're stuck, you can't pivot, and you've burned half your runway just for a prototype that validates nothing. We've co-founded our own startups. We know what it's like to have to choose between architectural excellence and speed. That's why we don't ask that question anymore. We deliver both: MVPs in 3 weeks that are technically clean, maintainable, and ready to support 10x user load without collapsing. You're not a number to us. You're a partner. We think like founders: how to minimize risks, maximize learning, and build something smart with limited resources. Your runway is limited? We extend it by delivering fast without shortcuts. Your market is uncertain? We help you validate your hypotheses with a real product, not with PowerPoint slides.
From marketplace to SaaS to B2B2C, we've supported all types of startups. Here are the patterns we've successfully repeated, tested in production.
You have a marketplace opportunity, but don't know where to start. Seller side, buyer side, payments, ratings, support? In 4 months, a traditional agency bills you $80k and you're not sure it will work. You don't have that time or budget.
We deliver an MVP marketplace in 3 weeks: a product list, a simple matching system, payments with Stripe (webhooks, reconciliation), a basic rating system with moderation. You launch, collect real feedback, iterate. Architecture designed to support hundreds of sellers without rewrite.
You test your hypothesis for $15k instead of $80k. You discover what users really want in 2 months. After user feedback, you have a clear direction for v2: detailed reviews, favorites, advanced search. The code is clean, scalable, ready to explode in users.
You're building a SaaS for SMBs. Subscription billing, Stripe, webhooks, multiple tiers, usage-based pricing, invoices, trials... It's complex, there are legal pitfalls, and you can't mess up. A bad billing implementation = production nightmare, chargebacks, angry customers.
We integrate a mature billing solution from the start (Stripe Billing). Multi-tenant architecture with proper data isolation. Webhooks and event-driven architecture for payments. GDPR/tax compliance in place. User onboarding optimized for conversion. Invoice generation. Free trial management.
You launch your SaaS with solid billing and confidence. Stripe handles the complexity, we handle the integration. You win your first customers day 1. Zero missed payment issues or data leaks. You pivot pricing? It's easy to do.
Your team uses 5 different tools, Excel, and lots of manual copy-paste. You waste 5h/week on repetitive work. You want a custom internal tool, but it seems complex. You had a 2-3 month wait with an unresponsive freelancer.
We deliver an internal tool in 4 weeks. Simple interface, optimized for your team's exact workflow (we observe how you work today). SSO and granular permissions. Integrated with your existing tools (Slack for notifications, Google Sheets for export, Zapier). Zero onboarding friction.
Your team saves 5h/week of manual tasks. The tool pays for itself in productivity in 2 months. There's 0 usage friction because you tested the workflow with the real team. It's easily maintainable if an internal dev takes over later.
You need to sync data between multiple tools or expose an API for your partners. Webhooks, retry logic, error handling, rate limiting... It seems simple in theory, it's a trap in prod where 1% of requests fail.
We design a robust REST/GraphQL API. Webhooks with signature and exponential retry strategy. Graceful error handling with notifications. Rate limiting and monitoring. Updated OpenAPI documentation. Integration sandbox for your partners to test without breaking prod.
Your partners integrate in 2 days without contacting you. You have complete visibility on every request and error. Zero downtime caused by a broken integration. Technical debt is minimal, logs are accessible.
A lightweight and modern tech stack, combined with lean startup methodology. We build products your users love and your devs can maintain.
Modern stack (React, Next.js, Node.js, PostgreSQL). Two 2-week sprints. User testing at each iteration. Usage metrics in place before launch. No useless features, just what validates your product's core hypothesis.
No shortcuts. Clean code, unit tests, layered architecture (domain, use-cases, gateways). Infrastructure as Code, automated CI/CD pipeline. When you need to scale, you have a solid foundation that doesn't collapse.
Figma prototype validated with users before the first line of code. Consistent design system. Mobile-first responsive. Every screen designed for conversion. A/B testing ready, analytics integrated.
Automated production deployment. Monitoring, alerts, centralized logs. Auto-scaling for peak loads. Cloud cost optimization (not billing you $5k/month for 100 users). Security by default, GDPR compliant.
We don't just code what you ask. We question. Feature prioritization based on user impact, not your intuition. KPI dashboard. Data-driven decisions. You know why every line of code is there.
Our team has co-founded projects from scratch. We've experienced the rush to launch fast, the anxiety of pivoting at the last minute, the pressure from investors waiting for results. We've also experienced the pain of legacy code, hasty technical decisions that block you 6 months later, infrastructure that collapses under load the day you launch an important feature. Result: we've developed a methodology that balances speed and robustness. We don't believe in the myth of "move fast and break things". We believe in "move fast without breaking your business". Every technical decision is thought through with an 18-24 month horizon, not just this month's MVP. If we can avoid technical debt without losing a week, we take it. If we must accept it to deliver on time, we document it and have a repayment plan. We also master the specific challenges of startups: how to onboard your first users without burning the marketing budget, how to measure what really matters (retention > vanity metrics), how to organize your team for growth without chaos. We're not just devs in meetings. We're your technical sparring partners.
No waterfall, no 6 months of planning. We use a lean, iterative approach, with demos every 2 weeks and fast decisions based on real feedback.
We dig into your market, your competitors, your target users. We challenge your hypotheses with user interviews. Together, we define the truly minimal MVP: the 3-5 features that validate your hypothesis. Clearly defined scope, realistic timelines, identified risks and mitigation plan.
Iterative Figma design. Wireframes, user flows, moodboard. We test with real users: does the UX make sense? Are we solving the problem? Fast feedback loop. We don't write a single line of code until the design is validated by real users.
Agile development in 2-week sprints. Continuous deployment to staging. Demo every 2 weeks with your team, your advisors, potential users. Fast scope adjustments if needed. Clean code, tests written as we go, infrastructure designed for scalability.
You launch to your first 100 users. We systematically collect feedback. KPI dashboard in place: adoption, activation, day 7 retention, usage patterns. Data-driven decisions. We iterate quickly: which features to keep, which to sacrifice, what to add. The code must support these iterations without rewrite.
Production deployment with confidence. Monitoring, alerts, incident response plan. Auto-scaling configured and tested. We support you through the first 1000 users: cost optimization, fast fixes, features requested by early adopters. Architecture designed to scale 10x.
