A four-stage playbook, written down, small enough to fit in a weekly review.

We don't start a project on the strength of an SoW. We start with a week of structured discovery — stakeholder interviews, a technical spike into the messiest part of the system, a competitive read, and a written outcome contract that defines what 'done' looks like.

By the end of week one you have a document that the founder, CTO and CFO can all sign without ambiguity. If we conclude the project shouldn't ship as scoped, we say so — and we've earned the fee for saving you the next six months.

• Stakeholder interviews (3–6)
• Technical risk spike
• Outcome contract
• Architecture sketch
• Fixed-fee proposal
• Eval target definitions

System architecture, interaction design, and the AI evaluation harness — all delivered as artefacts you can mark up before a single production commit. For LLM features we write the eval before we write the prompt. For SaaS surfaces we hand you a clickable prototype with real data shapes.

Design at Devmint is the cheapest place to be wrong. We aggressively prototype against the parts of the system most likely to fail and revise the architecture out loud.

• System architecture diagram
• Hi-fi clickable prototype
• Eval harness + datasets
• Guardrail specification
• API contracts
• Cost & latency budgets

Two-week sprints, one Friday demo per week, staging environment live from day one. Production from week one behind feature flags. You see the real system, with real data, every single week — never a 'big reveal' at the end.

The principal engineer who scoped the project ships code on it. There is no hand-off layer to a junior team. Code review is mandatory and our staging deploys are public to your team.

• Two-week sprints
• Live staging from day 1
• Weekly Friday demo
• Production feature flags
• Per-sprint eval reports
• Continuous code review

Every engagement includes 90 days of operate-and-improve work after launch. We run SLOs, on-call rotation, weekly cost & eval reviews, and a monthly roadmap working session with your team.

About 85% of our clients renew into a long-term embedded engagement after that 90-day window. The rest leave us a documented, instrumented, transferable codebase their internal team can take forward.

• SLO definition + monitoring
• On-call rotation
• Weekly cost & eval review
• Monthly roadmap session
• Quarterly architecture review
• Documented handoff (optional)
