Every week, I’m opening up the build of Arthur — what we’ve shipped, what we’ve learned, and what’s coming next.
Edition #1 covers the foundations and the roadmap we’ve now locked in.
Arthur is your mentor, co-founder and team
One conversation on the front. A full organisation working behind it — quietly, instantly, just for you..
This isn’t a weekend experiment — it sits on thousands of hours of content, interviews, masterclasses, workshops, a brutal problem-fit challenge, and the frameworks and founder knowledge we’ve already baked into Fusion42.
Arthur builds your foundations and keeps them tight in the background, while sharpening the tactics you need to win in the weeks and months ahead.

✅ What Arthur Does for You
🚀 One conversation to run your startup
Tell Arthur what you need. Get back clear plans, assets, updates and decisions you can act on.
🏛️ Builds your foundations
Keeps the core functions tight — governance, legal, finance, people, ops and reporting — so you’re not duct-taping later.
🧪 Tests and validates your thinking
Checks assumptions, pressure-tests ideas and flags risks early, before you burn time or money.
📈 Plans your growth
Generates GTM strategies, campaigns, sales scripts, outreach and retention plays that actually ship.
💸 Prepares your raise
Turns traction and numbers into investor updates, decks, and a live, always-ready data room built for diligence.
📂 Keeps your data room alive
Every update, metric, file and artefact is versioned, structured and synced — so your data room is always investor-ready.
📝 Drafts your documents
Produces investor updates, one-pagers, hiring briefs and product specs — clear, fast and on point.
📊 Scores your progress
Shows where you’re strong, where you’re stuck and what to fix next — no guessing, no self-delusion.
🧠 Remembers everything
Stores files, facts, feedback and experiments — linked, versioned, and instantly retrievable.
🤝 Works with you and for you
You set direction. Arthur handles the heavy lifting — giving you back time, clarity and work that moves the needle.
✅ Inside that organisation
Arthur — The Architect
Understands what you’re trying to achieve and works out the job behind the words.
Orchestrator — The Operator
Sends the right tasks to the right teams so nothing gets stuck.
Facts & Changefeed — The Source
Keeps everything grounded in truth — citations, timestamps, version control — not wishful thinking.
17 Specialist Leads — The Departments
GTM, content, sales, retention, fundraising, tech, people, finance, legal, governance — the functions every startup depends on.
Hundreds of Sub-Agents — The Teams
Spun up dynamically through Jiva.ai to research, analyse, draft and refine in seconds.
And the founder experience stays simple:
“I tell Arthur what I need. I get back clarity, time, and work I can move with.”
Here’s the build plan that brings that experience to life.
✅Arthur Build Roadmap — Beta at Week 10
Weeks 0–1 — Foundations: Give the Founder a Stable Base
Goal: Build the environment Arthur and the agent team will operate in.
New Fusion42 site and platform infrastructure ✅
Fusion42 website — rebuilt for humans and LLMs.
We’ve given the Fusion42 site a proper rebuild so it talks to both people and machines. The new shell is live with clean URLs, an internal /facts spine, and structured data (schema, JSON-LD, etc.) so AI tools can actually understand, trust and cite us instead of guessing from loose pages.
Internal knowledge base where The Source will hold truth ✅
Arthur project initialised — a clean, predictable foundation ✅
Core backend wiring is now live on AWS — structured data, file storage and vector search, all provisioned as code and ready for The Source to keep a clean, reliable record of truth.
Arthurs agentic blueprint built in Jiva.ai
Agent impact: The agentic team is already being developed on Jiva.ai — this phase builds the house they’ll work inside. ✅
Coming up
➡️ Weeks 1–2 — Core App: Shape the Space Around the Founder
Goal: Build the core application where conversations and decisions will happen.
Core app shell: navigation, screens, layouts
Authentication and access control
Initial flows The Operator will later route tasks through
Agent impact: Agents keep evolving in parallel; we’re constructing the “workspace” they’ll use to deliver value to the founder.
➡️ Weeks 3–4 — Conversation Layer: Give the Founder a Clear Voice Back
Goal: Let Arthur listen properly, interpret intent, and respond with clarity.
Primary chat interface
Fusion42-tone responses — direct, useful, no theatre
Logic for The Architect to understand meaning, not just messages
Agent impact: Arthur starts responding in a way that saves the founder time; the Operator and early departments begin handling small internal routing tests.
➡️ Weeks 5–6 — Memory & Agents: The Organisation Comes Online for the Founder
Goal: Switch on the internal teams that turn intent into work.
Document upload and storage so The Source can maintain truth
Data model for startups, assets and updates
Jiva.ai integration so:
The Operator can coordinate real work
17 Departments activate
Teams spin up instantly for research, drafting, analysis and checks
Agent impact: The loop comes alive: Architect interprets → Operator routes → Departments brief Teams → Source validates. The founder gets clarity without the heavy lifting.
➡️ Weeks 7–8 — Product & Templates: Free the Founder’s Time
Goal: Remove as much founder busywork as possible.
Plans, billing and accounts
Usage analytics
Turn the usual founder time-sinks — GTM plans, board packs, investor updates, basic tech docs — into clear first drafts, so time goes into decisions, not formatting
Agent impact: The stack now outputs shippable work, not just answers — saving the founder hours they normally lose to admin and document building.
➡️ Weeks 9–10 — Hardening & Beta: Make Sure the Founder Can Trust It
Goal: Run full end-to-end journeys under pressure.
We simulate real founder jobs:
Founder → Architect
Architect → Operator
Operator → Departments
Departments → Teams
Teams → Source
Source → clean output the founder can use
We:
Fix speed, stability and cost
Tighten handovers across the chain
Add monitoring, onboarding and support loops
Outcome at Week 10: Founders meet Arthur as intended:
The founder stays the hero. Arthur handles the heavy lifting. Time and clarity come back into the founder’s life.
Agent impact: The whole chain is stress-tested; behaviours and fallbacks are tuned for a confident, controlled beta.
PS: Tech Notes for Builders
Under the hood, Arthur runs on a Jiva.ai multi-agent stack, supported by a bespoke middleware layer that handles the real intelligence:
Architect layer for intent interpretation, contextual reasoning and job decomposition
Middle Layer (Arthur Intelligence Engine):
maps intent → required departments
evaluates confidence and ambiguity
enforces schema requirements, field definitions and controlled vocabularies
handles fallbacks, retries and escalation
decides when to create new sub-agents and how deep the chain should go
manages routing rules, workflows, memory access and tool-calling
ensures every output is grounded in The Source
Operator (router) for coordinating departmental tasks and maintaining flow
The Source for strict truth management — citations, timestamps, RAG over structured stores
17 departmental schemas with deterministic prompt patterns and quality gates
Sub-agents spun up dynamically for research, drafting, analysis and comparison
Continuous evals to keep behaviour stable as the system scales
This isn’t free-form “agent chaos”. It’s a structured, schema-led, middleware-managed organisation designed for reliability, traceability and speed — with Arthur’s middle layer acting as the intelligence that decides what should happen, in what order, and why.
FOR THE ❤️ OF STARTUPS
Help steer what we build next
I’m not building Arthur in a vacuum.
If there’s a workflow, bottleneck or ugly bit of founder work you want Arthur to take off your plate, tell me.
What you’re trying to do
What slows you down
What “done” would look like if Arthur nailed it
These go straight into the build plan for the next sprints.
