Everything you need to know about working with Key Brains.

General

We work with seed-stage startups, Series A–C scale-ups, and established enterprises across all industries. Our sweet spot is ambitious technology companies that need senior engineering talent and strategic architecture guidance without the overhead of building a full in-house team immediately. Clients range from 2-person founding teams to 500-person enterprises across 20+ countries.

For a new project engagement, we can typically have a dedicated team starting discovery within 5–7 business days of contract signing. For dedicated developer hiring, we present qualified, pre-screened candidates within 3 business days. Specialised roles (Rust/Solana engineers, ML research engineers) may take 10–14 days to source. We do not compromise on talent quality to meet an arbitrary start date.

Yes, always — before any confidential project discussion begins. We sign mutual NDAs covering your business plans, technical architecture, intellectual property, and any sensitive data shared during the engagement. Our standard NDA has no expiration date and explicitly covers every team member assigned to your project.

Hiring & Team

Yes. Our dedicated developer model embeds senior engineers directly in your team — attending your standups, using your project management tools, and reporting to your engineering managers exactly like in-house employees. Minimum engagement is 3 months. Engineers work 40 hours per week with meaningful timezone overlap for your location. Most clients who start with a 3-month engagement extend to 12–24 months.

Senior-only team — we do not put junior developers on production code. Every pull request requires a code review from a second experienced engineer before merge. Automated test suites are written alongside features, not retrospectively, targeting 80%+ coverage on core business logic. All production deployments go through staging with automated smoke testing. We have never had a client lose production data due to a deployment we executed.

Pricing & Timeline

A well-defined MVP typically costs $15,000–$45,000 and takes 8–14 weeks. A full SaaS platform typically costs $60,000–$180,000 over 5–9 months. Dedicated developer rates range from $40–$75 per hour depending on seniority and specialisation. We provide a detailed estimate with a line-item breakdown and risk factors after the discovery call — never a vague range chosen to win the conversation.

Every project includes 30 days of complimentary bug-fix support after launch. After that, most clients move to a monthly maintenance retainer covering security patches, dependency updates, infrastructure monitoring, and minor feature work. Critical incident SLA: 2-hour response, 8-hour resolution target for production-down scenarios. We have never missed a critical incident SLA.

Services & Process

Most projects begin with a 1–2 week paid discovery and architecture sprint, producing a detailed system design document, technical specification, and an accurate project estimate with line-item breakdown. Development follows in 2-week agile sprints with a working, deployed demo available every Friday. You know exactly where your project stands at every point in the engagement.

100% of the code, architecture, and intellectual property is yours from day one. IP assignment is included in our standard contract — we retain no rights to use your code in any form. Full source code, inline documentation, and deployment runbooks are delivered at project completion, or at any point on request during the engagement.

Fixed-price engagements: any scope change is costed and requires written approval before work begins. If we mis-estimate scope through our own error, we absorb the overrun — we have not passed an estimation error cost to a client in 3 years. Time-and-materials engagements: you receive weekly hour reports and can adjust scope in real time. There are no surprise invoices.

Technical

We choose technology to match requirements rather than defaulting to what we are most comfortable with. Our most-used stack: React / Next.js frontend, Node.js / Python backend, PostgreSQL database, AWS or GCP infrastructure, Docker / Kubernetes deployment. Mobile: React Native or Flutter. AI/ML: Python, PyTorch, FastAPI, Hugging Face ecosystem. Blockchain: Solidity for EVM chains, Rust for Solana.

Yes — project rescue is a specialisation of ours. We begin every rescue with a 1-week paid code audit that produces a detailed written assessment covering architecture quality, security posture, test coverage, technical debt prioritisation, and realistic effort to complete or stabilise. We tell you exactly what we find — if the codebase is genuinely unsalvageable and a clean rebuild is the right answer, we will tell you that directly rather than taking on expensive remediation work that cannot succeed.
