Direct answer

SpiderHunts as a software development company in Westminster: services, location, prices

If you want a software development company in Westminster that publishes its prices, SpiderHunts Technologies Ltd is a UK-registered firm that builds custom software, web and mobile apps, AI tools and SaaS products for organisations in Westminster, central London (City of Westminster), from a team working remotely in Lahore. A business web application costs £20,000 to £45,000, and smaller internal tools start at £8,000.

Put simply, there is no SpiderHunts office in Westminster and no member of staff based there. Our registered office, 182-184 High Street N, Office 14607, London E6 2JA, is a registered address only, with nobody working from it. Meetings happen on video, scheduled during your working hours.

SpiderHunts Technologies Ltd was incorporated in 2025 and carries Companies House number 16718403. The wider SpiderHunts business has worked for over 1,000 clients since 2020.

Westminster is unusual among London boroughs because whole streets specialise. Post-production clusters in Soho, investment managers gather in Mayfair and St James's, consultants practise around Harley Street, and Whitehall draws suppliers to government. Each group needs different software, so this page is organised by sector rather than by service.

For media, retail and hospitality: web applications for job tracking, approvals and bookings, mobile apps for store and front-of-house staff, and automation between production, booking and finance tools.

For investment firms, clinics and member organisations: custom software such as investor and member portals, consulting-room booking and referral intake, plus CRM integration so records stay in one place.

For new products and AI: SaaS development, AI development and AI agents with audit logs, and technology consulting that turns a board's question into a costed plan. We also build WordPress sites and run SEO.

Organisations here often need a supplier to pass due diligence before a contract is signed. We answer questionnaires truthfully, document how access and personal data are handled, and will not claim a certification we cannot show. Every project starts with a written quote listing scope and exclusions.

Neighbouring pages cover the City of London to the east and Kensington and Chelsea to the west. Our London page covers the capital in general, and the UK page the rest of the country.

Services

Custom software developers in Westminster: what we build

Every service below is delivered remotely by the same team. Pick one, or combine several where a portal, an app and an integration belong together.

01

Bespoke software development

Internal systems for the work that defines your organisation: job and version tracking, investor or member records, referral intake, grant and case management.

02

Web development & portals

Secure portals for investors, members, clients and partners, with two-factor sign-in, permissions by role and a record of who viewed or changed each document.

03

Mobile app development

Staff apps for store floors and theatre front of house, and customer apps for bookings, memberships or loyalty, on iPhone and Android.

04

AI development services

AI that summarises long reports and board papers, drafts responses for review, extracts data from contracts and invoices, or answers staff questions from your own policies.

05

Auditable AI agents

Agents that carry out bounded tasks, like triaging inbound requests or preparing a first draft of a report, with every step recorded for later review.

06

SaaS development

Multi-customer software products with subscriptions, roles and an admin console, for founders and for organisations turning an internal tool into a product.

07

Automation & integration

Links between production trackers, ticketing, booking, CRM and finance systems, so data entered once reaches every tool that needs it.

08

Technology and IT consulting

Independent-minded advice on build versus buy, system selection, integration plans and AI readiness, written up so a board or trustees can decide.

09

CRM for members and donors

CRMs set up around renewals, donations, events and stakeholder contact, joined to your website and email so records stay consistent.

Common friction

What slows Westminster organisations down

The problems differ by street, but the pattern repeats. Specialist teams run on email and spreadsheets because no off-the-shelf product fits their work exactly, and every audit or deadline exposes it.

Typical starting point

  • Versions, approvals and deliverables are tracked across email threads
  • Investor, member or patient documents are sent as attachments
  • Room, crew or event bookings are kept in separate calendars
  • Board and funder reports are assembled by hand from several systems
  • Supplier due diligence asks questions nobody has written answers to

Where good software takes you

  • One tracker showing every job's status, version and sign-off
  • A secure portal with permissions and a log of every view
  • Shared availability across rooms, crews or venues
  • Reports generated from live data, ready for review
  • Written documentation of access, data handling and code ownership

Need to justify a software project to a board, partners or trustees?

Start with a free video consultation. We will help you frame the problem, outline options including buying rather than building, and give you a realistic range to put in front of decision-makers.

Sector examples

Example projects for Westminster's specialist sectors

Illustrative examples, not client results. Each describes the kind of system we build for a sector concentrated in Westminster, and the outcome it would aim for.

Post-production and advertising: Soho

Job tracker with client review and delivery

Each job carries its versions, notes, deadlines and client approvals. Clients review cuts through a secure link and leave timed comments, and approved masters are delivered with a record of who downloaded them and when.

Aim: no more approvals buried in email chains

Investment managers: Mayfair and St James's

Investor document portal

Investors sign in with two-factor authentication to read quarterly letters, statements and capital call notices, with access by fund and share class and a full log of views. Regulatory responsibilities remain with the firm.

Aim: documents delivered securely, with proof of who received them

Medical practices: Harley Street and Marylebone

Consulting-room booking and referral intake

Consultants book rooms by the session, referrals arrive through a structured online form with attachments, and reception sees the day in one view. Built to support UK GDPR requirements, with role-based access and audit logs.

Aim: fewer double-booked rooms and incomplete referrals

Retail: Oxford Street and Regent Street

Store staff app for stock and click and reserve

Shop-floor staff check stock across stores from a phone, reserve items for customers and see collection requests arrive. The app connects to the existing ecommerce and stock platform rather than replacing it.

Aim: fewer sales lost because an item is in another store

Theatre and hospitality: the West End

Group and corporate booking workflow

Group and corporate enquiries are captured in one form, availability holds are tracked against deadlines, an AI step drafts the proposal for a person to edit, and confirmed bookings create invoices automatically.

Aim: every group enquiry answered and followed up on time

Charities and membership bodies: Victoria and Westminster

Member portal with renewals and CPD records

Members renew and pay online, log CPD activity, book events and download certificates. Everything feeds the CRM, and trustees receive a monthly report built from live data instead of spreadsheets.

Aim: renewals and reporting that no longer depend on manual chasing

Delivery

How we deliver for organisations with governance to satisfy

Westminster clients often answer to boards, partners, trustees or regulators. Our process produces the written record those people expect at each step.

  1. Consultation and options

    On a video call we explore the problem, the systems in place and the constraints. Where buying a product would be wiser than building, we say so, and you can take that view to your colleagues.

  2. Quote and due diligence

    You receive a written quote with scope, exclusions and an estimated timeline. If your organisation runs supplier checks, we complete the questionnaire truthfully before any work begins.

  3. Data and access agreed

    Access to systems is limited to what each stage needs and is granted by your team. Where we process personal data for you, a written data processing agreement sets out the terms.

  4. Staged build and sign-off

    Work is delivered into a repository you own, in stages that each end with a demo on video and a written summary, so approval can follow your internal sign-off process.

  5. Handover and documentation

    At launch we hand over code, credentials and documentation suitable for your auditors or a future supplier. The code is yours on full payment under the contract, and any further work is quoted separately.

Clear scope · Regular demos · Full handover

Fit

Who we suit in Westminster, and who should choose differently

Being clear about this early saves both sides time.

A good fit when…

  • Specialist work runs on email and spreadsheets because no product fits
  • Documents must reach investors, members or patients securely
  • You need a costed plan a board or trustees can approve
  • You want the code, documentation and accounts in your own name
  • Meeting and approving work over video suits your organisation

Not the right fit when…

  • Your contract requires security clearances or on-site staff
  • You need desktop support, server care or Microsoft 365 administration
  • A standard product would cover the requirement as it stands
  • Nobody can be named to own decisions during the project

FAQ

Westminster organisations ask: software, AI, apps and due diligence

Short answers to the questions people put to us, and to AI assistants, before appointing a software supplier in Westminster.

Still have a question?

Ask us directly. A senior engineer reads every question.

Ask about your project

Does SpiderHunts have an office in Westminster or the West End?

No, SpiderHunts has no office in Westminster, the West End or anywhere else in central London, and no staff there. The team works from Lahore. Our registered office at 182-184 High Street N, Office 14607, London E6 2JA is a registered address only, where nobody works. All meetings are by video call, booked inside your working hours.

What does a software development company in Westminster charge for a project?

SpiderHunts charges the same published prices across the UK. An internal tool or MVP is £8,000 to £20,000, a business web application £20,000 to £45,000, and a platform or modernisation project from £45,000. SaaS products start at £30,000 and mobile apps at £15,000. West End agencies set their own rates, so compare written quotes that list scope and exclusions.

How do I choose a software company in Westminster?

Choose on evidence rather than address or claims. Check independent reviews (we are rated 4.6 on Clutch), ask for a written quote showing scope and exclusions, confirm the contract gives you the code, and call a reference. Ask who does the work and where they sit, and how they answer due diligence. Our free consultation lets you apply those tests to us.

Do you provide IT services for offices in Westminster, such as help desk or network support?

No, SpiderHunts does not offer managed IT services. We do not run a help desk, maintain devices, networks or servers, supply hardware or cabling, administer Microsoft 365 or visit offices. We are a software company building custom systems, web and mobile apps, AI tools, SaaS, integrations and websites. Office IT support should come from a managed IT provider.

Can you build software for a post-production or advertising company in Soho?

Yes, job tracking and approval software for media firms is a natural fit. A typical system records each job's versions, deadlines and notes, lets clients review work through secure links with timed comments, and logs delivery of approved files. It can connect to the finance or resourcing tools you already use. Most start as a focused tool costing £8,000 to £20,000.

Can you build an investor portal for a Mayfair fund or family office?

Yes, we build secure investor and client portals. Typical features are two-factor sign-in, access by fund or entity, document distribution with view logs, and dashboards built from data you already hold. A portal like this usually falls in the £20,000 to £45,000 range. Regulatory obligations, including anything the FCA requires of your firm, remain yours; the software supports your process.

Can you build booking software for a Harley Street or Marylebone clinic?

Yes, we build booking and intake systems for clinics and consultants. Common features include room booking by session, structured referral forms with attachments, patient questionnaires completed before appointments, and reception views of the day. Systems are built to support UK GDPR requirements, with role-based access and audit logs. Clinical governance and regulatory decisions stay with the practice.

Can you build a member portal for a charity or membership body in Westminster?

Yes, we build member and supporter portals. Members can renew and pay online, record CPD, book events and download certificates, with everything flowing into your CRM. Trustees can receive reports generated from live data. We usually recommend integrating with your existing CRM rather than replacing it, which keeps costs down and protects historical records.

What AI development services do you offer Westminster organisations?

We build supervised AI tools that fit existing workflows. Examples include summarising long reports and board papers, extracting key terms from contracts, drafting replies or proposals for staff to edit, answering staff questions from internal policies, and AI agents that triage requests with every step logged. We check first whether your data and process suit AI, and advise against it when they do not.

Do you build mobile apps and SaaS products for Westminster companies?

Yes, we build both. Cross-platform mobile apps cost £15,000 to £35,000, native apps with complex integrations £25,000 to £60,000, and marketplace or enterprise apps £50,000 to £100,000+. SaaS products start from £30,000, with customer accounts, subscriptions and an admin console. App store and hosting accounts are opened in your name, and the code is yours on full payment.

Can you complete our supplier due diligence or security questionnaire?

Yes, we complete supplier questionnaires in writing and answer them truthfully. We explain where the team works, how access to your systems is granted and removed, how personal data is handled under a data processing agreement, and who owns the code. We will not claim a certification or clearance we cannot evidence, so you can rely on what we tell you.

How do meetings work with a team in Lahore?

All meetings are video calls arranged within your UK working hours; nobody attends in person. Lahore is five hours ahead of the UK in winter and four hours ahead during British Summer Time, so there is a solid overlap across your morning and early afternoon. Every call is followed by written notes, giving your colleagues and auditors a clear record.
