1. 01What is Minimum Viable Architecture?+

   Minimum Viable Architecture is the smallest technical foundation that lets an MVP launch, serve real users and evolve without forcing an immediate rebuild. It is not enterprise-perfection — it is the early decisions that are expensive to reverse later: account and role model, data model, deployment, integrations and operational visibility. Just enough that the V1 isn't already a rewrite target on day one.

2. 02What does an MVP engagement include?+

   We start with a 5-day Architecture Sprint to size the work, then scope a build: a Lean MVP / V1 (6–10 weeks, validation-stage product), a Production MVP (10–16 weeks, first paying customers) or a B2B SaaS V1 with diligence-ready engineering artefacts (14–20 weeks, a multi-domain build scoped without turning it into an enterprise-agency project), followed by post-launch iteration. We give you a fixed scope and quote after a 30-minute scoping call; the Architecture Sprint fee credits toward project work if we proceed together.

3. 03How long does MVP development take?+

   Architecture Sprint: 5 days. Lean V1 (validation scope): 6–10 weeks. Production MVP (auth, billing, integrations, admin panel): 10–16 weeks. B2B SaaS V1 with diligence-ready engineering artefacts (multi-domain, tenant isolation, audit trail): 14–20 weeks. Faster than the lower bound usually means scope cuts that show up as rewrite pressure in month 4.

4. 04Java/Spring or Node — which is right for our MVP?+

   Java/Spring when your roadmap includes enterprise B2B sales (DACH financial services, regulated B2B, banking customers expecting JVM-based security audits). Node when general B2B SaaS — faster to staff, smaller ops footprint, better default for product velocity. We help you decide in the Architecture Sprint.

5. 05Can you build billing, subscriptions and admin workflows?+

   Yes. We can include Stripe, PayPal, Paddle or other payment providers where billing is part of the product model, and we design payment and subscription states explicitly so pricing, access, refunds and admin visibility do not become hidden edge cases. Admin tools and operational workflows are built alongside the product, not bolted on after launch.

6. 06Can you continue development after launch?+

   Yes. After launch we can continue with feature iterations, technical cleanup, monitoring, analytics, integrations and roadmap support. The goal is to keep the product moving without creating dependency on undocumented code.

7. 07What if we already have a prototype or unfinished MVP?+

   Common engagement. We can take over from prototypes, Figma designs, partial codebases or early no-code experiments — assess what's there, then either help finish or restart on the right foundation. The first step is usually the Architecture Sprint: separate what should be reused from what should be rebuilt properly for production. For acute cases — failed contractor, stuck rewrite — see our Software Rescue service.

8. 08Can you make our MVP diligence-ready?+

   Often yes. Architecture decision records (ADRs), audit logs, sub-processor inventory, tenant isolation documentation, deployment history and basic test coverage can all support technical review during fundraising, enterprise procurement or partner onboarding. Some engagements target diligence-oriented documentation over a 90-day milestone.

9. 09Can AI be part of the MVP from the start?+

   Yes. When AI is core to the product — a copilot, assisted workflow or smart search — we design it into the architecture during the build, on the same stack, with human review where outputs affect users or money. It's an extension of the MVP scope, not a separate engagement.

10. 10Which AI provider do you use?+

    We're vendor-neutral. The provider (Anthropic, OpenAI, others, or EU-hosted / local where data sensitivity requires it) is a per-use-case decision made in the architecture phase — not a default and never tied to partner status.

11. 11Is AI-native different from your AI automation service?+

    Yes. AI-native means AI built into a new product as we build it. AI automation adds AI to systems you already run. Same capability, different stage.
