Quick answer

What is it like hiring a custom software company from Bristol?

SpiderHunts Technologies is a software and AI development company registered in the United Kingdom, with an office in London and engineers in Lahore. We do not have a Bristol office. We work with Bristol companies remotely, in the same time zone and the same working day, under UK contracts in sterling.

Bristol is the UK's aerospace and silicon design centre, and the work reflects that. Most of what we are asked for in the South West is operational: the system that sits between the platforms you already run, the workflow nobody has automated, the reporting that gets rebuilt by hand every month.

We would rather tell you a problem does not need custom software than sell you a build. If a configuration change or a better report solves it, we will say so.

What we build

What London businesses hire us to build

The engineering work you would otherwise give an in-house team, built around your process and released into your own cloud account.

01

Custom software & internal tools

Operations portals, client portals, approval queues, booking and case systems — the line-of-business software no product on the market fits without three workarounds.

02

Tooling around a regulated core

Client onboarding and verification flows, reconciliation and reporting views, exception queues and the audit trails a City or Canary Wharf firm has to be able to produce on request.

03

AI agents & assistants

Agents that triage a shared inbox, research, summarise, draft and prepare work for a person to approve, running inside your own tools with guardrails and logs.

04

AI integration into the systems you run

AI added to Microsoft 365, Salesforce, HubSpot, Xero, Sage and your own database through their APIs, rather than a parallel tool nobody opens.

05

Web & mobile applications

Customer-facing products, member and investor portals, and mobile apps for field, site and sales teams working across Greater London.

06

SaaS & product engineering

First releases and multi-tenant platforms for London software companies: authentication, billing, admin, partner APIs and the analytics you need to learn something real.

07

Automation & document capture

Invoices, delivery notes, certificates, applications and forms read on arrival, checked against your system of record, with only the unclear ones sent to a person.

08

Cloud, data & DevOps in UK regions

Infrastructure as code in AWS London, Azure UK South or Google Cloud europe-west2, data pipelines, CI/CD with review gates, and monitoring your on-call engineer can actually read.

Why it matters

Why Bristol operators outgrow their platforms

Most London projects we are asked about were already on someone’s roadmap. They stalled because the people who could build them were busy keeping the current systems alive, and because London engineering time is the scarcest thing in the building.

Before the system exists

  • Twelve subscriptions, four of which nearly do the job
  • Client data lives in three systems and agrees in none
  • Month-end reporting is an export-and-merge job by hand
  • Evidence for an audit or a review has to be reassembled
  • The workflow that differentiates you is the one no vendor supports

With software built around your process

  • One data model that every report and portal reads from
  • Integrations keep the systems you already pay for in step
  • Reporting is a page, not a monthly project
  • Access, changes and approvals are logged as work happens
  • Your differentiating workflow is what the software is built around

Examples

What we build for Bristol companies

Typical problems Bristol teams bring to us, and the software that addresses them. Illustrative examples of what we build, not client results.

Aerospace

Configuration and compliance evidence

Which build standard, which part, which certificate - tracked in a system rather than assembled from a shared drive when the auditor arrives.

Aim: evidence that is complete before it is asked for.

Semiconductor

Test and yield analysis

Test data pulled into one place so yield variation can be traced to process, lot or equipment rather than argued about.

Aim: finding the cause instead of describing the symptom.

Creative

Asset and version management

Knowing which version of an asset is approved, where it is used and what rights attach to it.

Aim: no more shipping the wrong cut.

Environmental

Sensor data and reporting

Field sensor data validated, gap-filled honestly and turned into the report a regulator or customer expects.

Aim: claims you can evidence.

Marine

Maintenance planning

Planned maintenance against actual running hours and condition rather than a fixed calendar.

Aim: intervention before failure, not after.

Spin-outs

Research code to product

Taking something that works on a researcher's laptop and making it something a customer can run, monitor and pay for.

Aim: a product rather than a prototype.

How we work

How a London engagement runs

Short stages with a clear output each time, run inside your working day so nothing sits waiting until tomorrow.

  1. Free scoping call — or a meeting

    Thirty minutes on the problem, the systems involved and what ‘done’ looks like. If you would rather do it in person, we can arrange that in London. You get a written quote with scope, exclusions and an estimated timeline.

  2. Access, data and rules

    We agree which cloud account and London region the work runs in, who grants access to which systems, and what personal data is involved, before any of it moves. Where we handle personal data for you, that sits under a written data processing agreement.

  3. Build with weekly demos

    Work lands in your repository from the first week. There is a written update each day and a demo each week in London hours, so you see the real thing rather than a status report.

  4. Testing and staged release

    Automated tests and scans run in the pipeline, your team reviews access and logging, and we release in stages with monitoring switched on and a rollback path agreed in advance.

  5. Handover

    Documentation, runbooks, infrastructure definitions and code stay in your own accounts and repositories, so your team or any other firm can pick it up. Ongoing development or support is quoted separately if you want it.

Clear scope · Regular demos · Full handover

Is it right for you?

When a custom build is worth it in London

We would rather tell you a product already on the market covers this than build you something you did not need.

A good fit when…

  • The process is part of what makes the business money
  • Two systems hold the same data and neither is authoritative
  • A vendor’s roadmap will not reach your problem this year
  • The data has to stay in UK infrastructure you control
  • Someone internally owns the decisions and can grant access

Not the right fit when…

  • An existing product already covers the whole workflow
  • Volumes are low enough that a person handles them in minutes
  • Nobody internally can approve designs or sign off access
  • The job needs engineers physically on your premises every day

Make an informed choice

Buy a product, hire in London, or build it with us?

Nearly every London enquiry starts as this question. We answer it before quoting, because getting it wrong is expensive in both directions.

Sectors

The industries Bristol runs on

Bristol is built on aerospace and defence, semiconductor and silicon design, creative and animation, environmental technology, and marine. That mix produces a particular class of software problem: operational data in volume, systems that cannot be switched off, and a regulator or an auditor somewhere in the chain.

FAQ

Custom software development in London — FAQs

Common questions from Bristol businesses about working with us.

Still have a question?

Ask us directly — a senior engineer will get back to you.

Ask about your project

Do you have a Bristol office?

No. We are UK-registered with a London office and engineers in Lahore. Bristol clients work with us remotely in the same time zone.

Can you work on defence-related projects?

It depends entirely on the clearance and residency requirements. Our engineers are in Lahore, which rules out a great deal of defence work, and we would say so early rather than waste your time.

Do you work with university spin-outs?

Yes, and it is a common piece of work - the gap between research code and something a paying customer can run is usually larger than expected, and worth scoping honestly.

Can we meet in person?

Yes, and that is genuinely useful at the start of a project. We can meet at the office in E6, or somewhere more central if that is easier — the Elizabeth line and the Jubilee line make most of London reachable in well under an hour. Meetings are arranged in advance rather than available on demand, and we will not pretend otherwise. After the first session, day-to-day work runs over video, Teams or Slack and a shared board, because a weekly demo you can invite your stakeholders to beats a monthly meeting in a room.

How do contracts, invoicing and VAT work?

Projects are quoted and invoiced in pounds sterling by SpiderHunts Technologies Ltd against a written scope with milestones, under English law. Where UK VAT applies it is shown as a separate line and the position is confirmed in the quote before you sign, so the VAT figure is known well before the first invoice arrives. Payment by bank transfer or card. If your organisation has its own supplier terms, purchase order process or procurement portal, we work through them; larger London firms usually do.

Where will our data and our code live?

In your accounts, not ours. We deploy to AWS eu-west-2 in London, Azure UK South or Google Cloud europe-west2, inside your own cloud organisation, and code goes to your GitHub, GitLab or Azure DevOps. Engineers get named, least-privilege access that you can revoke at any time, and we keep production data out of development environments unless you specifically ask otherwise. If a project uses a large language model, we can route it through UK or EU endpoints and tell you exactly which data leaves your systems and which does not.

Will what you build meet UK GDPR requirements, and who deals with the ICO?

We build software designed to support UK GDPR and the Data Protection Act 2018, but compliance is a property of your organisation rather than of one system, so it stays your responsibility. In practice that means lawful-basis and consent records, data minimisation, retention and deletion rules, subject access and erasure workflows, encryption, role-based access and audit logging, documented so your DPO or adviser can review it. Registration with the Information Commissioner’s Office, your privacy notices and the decisions a controller makes are yours. Where we handle personal data on your behalf we work under a written data processing agreement, and we would rather develop against anonymised or sample data in the first place.

Do you work with FCA-authorised firms in the City and Canary Wharf?

We build software for them; we are not a regulated firm and we do not give regulatory advice. What that looks like in practice is engineering controls your compliance function can rely on: immutable audit logs of who saw and changed what, segregation of duties and four-eyes approvals, retention rules, evidence that can be exported rather than screenshotted, and reporting views that reconcile back to the source. Your compliance, risk or legal team defines the obligation; we build the system that enforces it and write down what it does. Any permission, attestation or regulatory sign-off remains entirely with you.

Do you do work for logistics and distribution businesses around the M25?

Yes. London’s distribution ring — Park Royal, the Heathrow air-freight estates, Croydon, the Thames Gateway and the London Gateway and Tilbury ports — runs on transport systems, carrier APIs and a great deal of paper. Typical builds are a depot dashboard that merges consignments and exceptions from more than one system, integrations with carrier and courier APIs, and capture of delivery notes and proof of delivery from a driver’s phone at the kerbside. Where routing and access charges matter, the administrative side of low-emission and congestion zones can be folded into the same workflow.

Can you build a first product for a startup in Shoreditch or King’s Cross?

Yes, and the useful question is usually not ‘what could we build’ but ‘what is the smallest thing that proves this works’. A first release is typically authentication, the one workflow that proves the idea, billing, an admin view and enough analytics to learn something from real users. We keep it deliberately small so you spend the rest of the runway on what the users actually tell you, and we will push back if a scope is trying to be version three on day one. See SaaS development for how those builds run.

What language do you work in, and can software ship in more than one?

We work in English, in writing and on calls. London is one of the most multilingual cities in the world, so customer-facing products often need more: we build interfaces so text, dates, currency and number formats can be translated, and so a right-to-left language does not break the layout later. The wording comes from your team or your translator — we do not sell translation — and we make sure the product carries it properly rather than having it bolted on after launch.
