# Robust Devs: Full Site Map > **Robust Devs** is a custom software and AI development company. We build the software, systems and operations businesses run on, with AI at the core, and every engagement opens with a written review of what you have and a plan for what to build next. That means MVPs, SaaS platforms, internal tools and mobile apps, either built from scratch or taken over from a previous agency, a contractor, or AI coding tools. The AI engineering is the production layer around LLMs, RAG, agents and evaluation rather than model training. Founded 2019, UK-registered (Companies House 16373064), remote-first, senior-only teams, frequently working as an ongoing technology partner rather than on single projects. This document lists every public route on robustdevs.co, organised by section, with the context an AI crawler needs to understand what each page covers. --- ## Home - **URL:** https://robustdevs.co/ - **Description:** The primary landing page. Introduces the company's positioning as a custom software and AI development company. Covers industry cards, engagement models, the delivery process, the tech stack, case studies, testimonials, a founder note and an FAQ. The hero leads with "Your Trusted Partner in Custom Software Development", followed by the line that carries the differentiation: "We build the software, systems and operations your business runs on, with AI at the core. Every project starts with a written review of what you have and a plan for what to build next." Hero CTAs go to contact and to scheduling a call. --- ## Services Robust Devs offers a tiered set of engineering engagements, from diagnostic to delivery to ongoing support. ### Engagement types (primary) - **The written review:** how every engagement opens, not a product you can buy Senior engineers read what exists: architecture, code quality, security, CI/CD, observability, team structure, and shipping cadence. The output is a written review of what you have and a plan for what to build next, with a 1-page action plan and a walkthrough call. It carries no price and is not sold separately. Where there is no code yet, the same read is done on the plan. - **Discovery Sprint:** https://robustdevs.co/services/discovery-sprint A 1–2 week engagement to co-create the product shape before committing to a build. Outputs include user flows, technical architecture, milestone acceptance criteria, a delivery plan, and a fixed build price. Designed for teams that have a product idea but need the scope defined before committing engineering resources. - **Project Build:** https://robustdevs.co/services/project-build Fixed-scope, fixed-price product delivery in 6–14 weeks. Includes design, development, testing, security review, deployment to client infrastructure, documentation, and 30 days of post-launch support. Client retains 100% IP ownership and controls all infrastructure accounts. - **Ongoing Product Engineering:** https://robustdevs.co/services/retainer A senior team (typically 2–5 engineers) integrates into the client's roadmap and ships alongside their internal team: working in their repos, attending their standups, using their ticket system. Monthly engagement. Robust Devs' internal AI tooling stack (code generation, review automation, test generation, documentation) runs on top of the delivery team. Suited for growth-stage companies with evolving roadmaps rather than a fixed-scope build. - **Project Rescue:** https://robustdevs.co/services/project-rescue Stabilisation and recovery engagement for products where a previous vendor left the work incomplete, unstable, or behind schedule. Begins with a written review on the current state, then either completes the build or stabilises it for handoff. - **Retainer:** https://robustdevs.co/services/retainer Ongoing engineering capacity at a predictable monthly cost. For teams that need maintenance, small features, and operational support on a shipped product without a full embedded squad. ### Service categories (capability pages) - **AI Development:** https://robustdevs.co/services/ai-development LLM application development, RAG system architecture, AI agent design, evaluation frameworks, and model observability.

Every price or claim about another company is read from that company's own page, recorded with the date it was read, and linked. Providers whose pricing could not be verified first-hand are omitted rather than quoted second-hand. Robust Devs appears in each table at its real position by price, not pinned to the top, and each page names the situations where a competitor is the better buy. Tables are re-checked quarterly. ### Fixed-price code audit services compared https://robustdevs.co/compare/fixed-price-code-audit-services A comparison of seven fixed-price code audit providers with published entry prices ranging from $49 to $15,000, covering Afterbuild Labs, Enviera, The Yellow Labs, Data Jackson, Robust Devs, Brival, and Ego Eimi. Explains what each price tier actually buys: under $1,300 is largely an automated scan, $1,300-$5,000 is where a senior engineer reads the system, $5,000-$15,000 is investor-grade diligence, and above $15,000 is transaction diligence. Robust Devs appears in the comparison without a published entry price, because our work is scoped per project. Includes guidance on when a fixed price is a red flag, what belongs in an audit report, and how AI-generated codebases change where problems cluster. ### Technical due diligence providers compared https://robustdevs.co/compare/technical-due-diligence-code-audit A comparison of technical due diligence providers who review startup codebases before a funding round, covering GreeLogix, Muneeb Hussain, BearingGate, Enviera, Robust Devs, Brival, Jezen Thomas, madewithlove, and Variant Systems. Published entry pricing ranges from $500 to $9,500, with several respected firms publishing no price and quoting after a call. Distinguishes interview-led diligence (team, process and key-person risk) from code-led diligence (repository read by feature path), which is the difference that separates providers at the same price. Also covers who commissions the review - investor, founder, or acquirer - and why a founder-side audit before the term sheet turns a discovered problem into a disclosed one. ### Audit, refactor or rebuild? https://robustdevs.co/compare/code-audit-vs-rebuild A decision guide for teams weighing what to do with an existing codebase. Argues that "fix or rebuild" is a false binary and lays out five paths: audit first, stabilise, refactor in place, incremental replacement (strangler pattern), and full rebuild, with relative time and risk for each. Names four signals that genuinely justify a rebuild - the platform itself is the constraint, change cost is rising rather than flat, nobody can predict the blast radius of a change, and the requirements are already understood - and explicitly excludes "the code is messy" as a reason. Covers the cost nobody estimates: undocumented requirements encoded only in the system being deleted. ## Work & Case Studies - **Our Work:** https://robustdevs.co/work Portfolio index page.
