Co-Founder, Managing Director & Technical Lead · Rheos App Ltd
Archie Roberts
I built and commercialised Rheos, a multi-tenant system that captures a small
business’s context, plans and produces its social content, publishes approved work and
tracks how that business appears across social, search and AI answers. It is now used by
50 paying UK businesses. I lead product, web and backend engineering, customer delivery,
sales and company operations.

2023—2024
Research Analyst Placement · ISS STOXX
Analysed FTSE 350 annual reports, governance structures and shareholder outcomes,
turning dense public evidence into consistent institutional research.
2021—2022
Operations, logistics and accounts
Coordinated nationwide rail delivery of COVID tests at InterCity Railfreight, then
worked as an Accounts Assistant at Annie’s Burger Shack Group.
AI experience
Research, model evaluation, production software and the work of operating a company.
Experience timeline
The progression covered more than software: model evaluation, product design,
deployment, sales, customer support, legal work and company operations.
Research and evidence
Used ChatGPT from launch for university research, then developed stronger source
discipline while analysing FTSE 350 annual reports at ISS STOXX.
Models and agent workflows
Worked across leading OpenAI, Anthropic, Google and open-model families using ChatGPT,
Claude Code, Codex and Antigravity; built MCP, session-transfer and multi-model review
workflows.
From prototype to MVP
Moved from manually coded websites to a multi-tenant product spanning brand context,
planning, generation, approval and publishing. Real businesses were using it by
January.
Production and paying customers
Took the first payment in April and reached 50 paying customers by July. Added
authentication, tenancy, billing, observability, recoverable publishing and customer
support.
Operating Rheos App Ltd
Alongside product and engineering, handled sales, onboarding, support, contracts,
trademark, legal work and accountancy, then prepared a Midlands go-to-market rollout.

Social planning, creation and publishing for small businesses
A customer starts with their website. Rheos stores editable context about the
business—services, audience, tone, proof points, locations, offers and visual
identity—then uses it to build a plan and create on-brand copy and visuals.
Customers edit or approve each post before it is published from the same workflow.
Analytics inform the next plan, while Search Visibility tracks how the business is
represented across social, search and AI answers.

The customer gives Rheos its sources once, adjusts the resulting brand context and
works from a repeatable plan rather than a blank prompt. Finished posts stay
editable, and nothing represents the business until the customer approves it.

Reports that a weekly content workflow that took hours now takes minutes.
AB Components
Reports that producing an on-brand post fell from roughly an hour to 10–15 minutes.
Two-person operating model
My co-founder leads mobile and contributes to technical R&D. I lead product, web and
backend engineering, customer delivery, sales and operations. Shared context, specialised
agents and connected systems let two founders cover several conventional functions.
Context, code and coordination
Linear, GitHub and a source-aware knowledge system keep plans, code and decisions
connected. Codex and Claude support research, implementation, review and QA.

Product and production
Multi-tenant application surfaces sit on Firebase and GCP, with asynchronous workers,
identity, billing, secret management, observability and explicit release gates.
The work that made Rheos a company was the infrastructure around the models:
keeping each customer’s data isolated, restricting what agents can do, running long
jobs safely in the background, controlling cost, recovering partial failures and
keeping a person in control of external actions.
1
Context: source-aware business knowledge composed for each task.
2
Tools: protected MCP and application actions that automatically use the authenticated customer account.
3
Execution: Cloud Tasks and idempotent workers for long-running jobs.
4
Economics: credit reservation, confirmation, refunds, cost ledgers and budget gates.
5
Quality: human approval, emulator-backed tests, Playwright, Sentry and release gates.
Selected technical projects — ALDR Ltd
Public examples of my work on persistent context, MCP tools, source quality and
human-controlled systems.
Experience across customers, product and engineering
My work at Rheos covers customer discovery, product design, implementation, deployment,
incident handling, cost control, support and commercial delivery.
