NexcurAI is one firm across five disciplines: cybersecurity, web development, AI product, SEO and GEO, and growth marketing. Every engagement ends with a Signature Handbook written for your company, not a generic template, so the knowledge stays when we leave.
Each line is standalone. Clients who bundle get more than a discount; they get a team that actually knows their context.
Manual exploitation validated by senior engineers. Claude handles correlation, pattern recognition, and report prose so you get findings in plain English, not 400 pages of tool output.
See security services →Strategy, RAG, agents, evals, and the cost model that stops surprises. We tell you when not to ship AI.
See product services →Greenfield or modernizing. Accessibility and performance as targets, not afterthoughts.
See web services →Classic SEO plus GEO structure and share-of-answer tracking across Perplexity, ChatGPT, Claude, Gemini.
See SEO services →Content, outbound, paid, analytics, and CRO. Real attribution. No vanity dashboards.
See growth services →Every engagement produces a living handbook written for your company: your stack, your industry, your voice. Your Security Handbook. Your Growth Handbook. Your AI Product Handbook. Claude generates the draft from a template we have refined across every past engagement. Our leads edit it. You own it.
Templates are ours. We refine them every engagement. Your inputs drive a tailored output that reads like it was written for you, because it was.
Every section has a change log. Retainer clients get quarterly refreshes as your context shifts. Full provenance, model and template version included.
When the CTO leaves or the marketing lead rotates, the handbook is onboarding day one. That is the durable value of this whole thing.
We maintain a versioned template library of every handbook type. Clients supply inputs through a structured intake. Claude runs the generation with tool use, prompt caching, and extended thinking. Every output is reviewed by the service-line lead before it leaves our building.
Versioned markdown skeletons per service line, refined across every engagement we have ever shipped.
Prompt caching, extended thinking, and tool use against your intake. Evals gate every template edit.
Structured profile, stack, voice, and integrations. Encrypted at rest. Never crosses tenant boundaries.
We are early. The first paying engagements are in flight, and signed case studies will land here as they close. We will not invent testimonials or attribute work to companies that do not exist.
In the meantime, every public deliverable is on the site. Read a sample handbook, browse specimen documents from each service line, or read essays on how the work gets done. They are how we work.
Twenty-four essays, sixteen guides, thirteen specimen documents. Public, free, no email wall. Go as deep as you need.
Tool use is not "Claude can call APIs." It is the single mechanism that turns a prompt into a program. What changes when we stop treating it as plumbing.
