Overview

SaaS & MVP Development by Evosec Consulting

Most SaaS MVPs fail for one of two reasons: they take nine months to reach a first customer, or they reach one and immediately fail a security questionnaire. Evosec's SaaS development practice is built to avoid both. We ship a production-grade multi-tenant product in 6–12 weeks, and our in-house penetration testers sign off on every release.

We've built B2B SaaS for fintech, HR-tech, logistics and health — for founders in Paris, New York, Austin and Tunis. Same process every time: fixed-price milestones, weekly demos, and a codebase your future CTO will be happy to inherit.

What's Included
▌ 01

Multi-tenant architecture

Tenant isolation at the data layer, per-tenant config, and the ability to run enterprise single-tenant deployments later without a rewrite.

▌ 02

Billing & subscriptions

Stripe (or Paddle / Lemon Squeezy) with plans, trials, usage-based metering, invoices, dunning and tax handling for EU VAT and US sales tax.

▌ 03

Auth, roles & SSO

Email/password, magic links, OAuth, 2FA — and SAML/OIDC SSO ready for your first enterprise customer.

▌ 04

Admin & analytics

Internal admin panel, product analytics events, and the MRR / churn / activation dashboards investors ask for.

▌ 05

API-first & integrations

Public REST API with keys and rate limits, webhooks, and integrations with Slack, HubSpot, Zapier and the tools your customers already use.

▌ 06

Security & compliance

Threat model at design time, SAST in CI, manual pentest before launch, GDPR data mapping, SOC 2-ready logging and audit trails.

FAQ
How much does SaaS MVP development cost?

A focused SaaS MVP with Evosec typically costs $15,000–$40,000 (≈ 14k–37k €) and ships in 6–12 weeks. That includes multi-tenant architecture, billing, auth, an admin panel and a pre-launch penetration test. Larger platforms are scoped individually, always fixed-price per milestone.

What stack do you use for SaaS?

Laravel or Node.js on the backend, Next.js/React with TypeScript on the front, PostgreSQL, Redis, Stripe for billing, deployed to AWS or Vercel with Docker and GitHub Actions.

Can you help us raise or pass due diligence?

Yes. Our SaaS builds come with the artefacts investors and enterprise buyers ask for: architecture docs, a security posture summary, pentest report and GDPR data map.

Do you work with non-technical founders?

Most of our SaaS clients are non-technical or have one technical co-founder. We handle product scoping, architecture and delivery, and we speak plain English (or French).
