Jonathan Simpson & Co. Start a project

Founder-led digital systems agency

We turn manual operations into systems that accelerate growth.

We work with businesses that have outgrown manual processes and need systems that simplify operations, not add more complexity.

We design and build automation systems, internal tools, and high-performance websites for ambitious businesses.

01 / Work

Selected projects, built end to end

Each project demonstrates a specific capability. For deeper detail, open the full case study.

Novomi Vax

Investor platform for an early-stage oncology startup. Engagement details shared on request.

JS&C Automation

An interactive live demo of our zero-data-retention agentic AI middleware: simulated compliance pipelines, a connector matrix, and an ROI calculator built to win SFC-licensed clients.

Archivum

Commissioned by an Oxford University student as part of her dissertation research, a workspace for reading and annotating old scanned documents that don't work with regular PDF tools.

BriefDoc

A free, no-login interactive document workspace that replaces static PDFs: draft, share, track how clients read, and collect digital signatures in the browser.

02 / Services

Three focused services, built to solve real operational problems.

We combine product thinking, software engineering, and systems design to deliver practical outcomes that teams can run with.

01

Automation Systems

Reduce manual overhead by turning repeatable operational work into reliable automated workflows.

  • Workflow Automation
  • Backend Systems
  • RPA
02

Internal Tools

Design and build internal products that help teams make decisions faster and operate with less friction.

  • Analytics Dashboards
  • UI/UX
  • CRM
  • RPA
03

Web Design & Development

Build fast, clear, conversion-ready websites that match your brand and perform under real traffic.

  • SSG/SSR
  • CDN
  • SEO
04 / Capabilities

Design, engineering, data, and automation in one delivery team.

We combine design discipline with engineering: workflow automation; RPA with integrations and APIs; PostgreSQL, SQL analytics, and reporting pipelines; Python with LLMs and computer vision where the problem calls for it; and modern frontends on Next.js, Astro, React, and Tailwind.

  • Design & Product

    Clarify messy workflows and shape practical experiences.

    • Product discovery and scoping
    • UI/UX design for internal tools and web
    • Logo and brand design
    • Figma-based design systems and handoff
  • Engineering & Architecture

    Build robust, maintainable software that teams can actually run.

    • Full-stack web development (frontend to API)
    • Performance-focused architecture decisions
    • Mobile-friendly responsive builds
    • Self-documenting code and handovers
  • Automation & Internal Tools

    Turn manual operational work into reliable automated systems.

    • Workflow audits and opportunity mapping
    • Automation hubs that tie together backends, APIs, and databases
    • Custom internal tool development
    • Process automation with monitoring and alerting
  • Artificial Intelligence

    Use data and AI where it genuinely improves outcomes.

    • SQL reporting, warehousing, and ETL-style operational pipelines
    • NLP, RAG retrieval, OCR, and decision-support workflows where they fit
    • Computer vision (OpenCV, YOLO-class models) when visuals drive the workflow

05 / Process

How we work

We follow a structured approach that keeps you informed at every stage, from initial audit through to a live system your team can operate independently.

01

Discover

We audit your current operations, map workflows, and identify the highest-impact opportunities for automation and improvement.

02

Design

We scope the solution, design the user experience, and plan a technical architecture that fits your existing stack.

03

Build

We develop in iterative sprints, integrating with your tools and testing at every stage so nothing breaks.

04

Deploy

We launch the system, set up monitoring and alerts, and hand over documentation your team can actually use.

05

Evolve

We iterate based on real usage data, adding features, refining workflows, and expanding scope as your needs grow.

06 / About

Small, technical, founder-led.

Simpson leads product delivery and full-stack engineering. Jonathan leads AI and data systems. Together we run a lean senior team and expand with trusted collaborators when scope demands it.

Simpson

Co-founder, Full-stack Software Engineer

Full-stack engineer and product-minded web developer. Current pursuing a Masters in Informatics at the University of Edinburgh. Leads end-to-end delivery from concept and UX through deployment and analytics.

Jonathan

Co-founder, AI Engineer and Data Scientist

AI engineer and data scientist. Final year data science student at The University of Hong Kong. Shapes data workflows, models, and backend services that turn ambiguous operational questions into practical tooling.

Bring us your messy operational problems, fragile workflows, or half-formed product ideas.

Contact

Let's work together.

Bring us your messy operational problems, fragile workflows, or half-formed product ideas. We will help you shape the right scope and ship a practical solution. If you are not sure where to start with AI or automation, we will help you find one or two high-impact projects that make a visible difference without disrupting your whole business.
