Local context

The Square Mile: a financial district with its own government

The City of London, the Square Mile, is the capital's main financial district. It is governed by the City of London Corporation, which has its own Lord Mayor and police service and serves a small resident population alongside a far larger daytime workforce. Unusually, businesses registered in the Square Mile can nominate voters in City elections. Through its Global City platform, the Corporation champions the UK's financial and professional services, from banking and asset management to insurance, legal services, fintech and regtech.

Insurance gives the City much of its character. The London Market is the world's largest commercial and specialist insurance and reinsurance market, home to Lloyd's and to hundreds of brokerage and insurance firms, with most of its capital coming from overseas. Lloyd's describes itself as the only insurance marketplace of its kind, bringing together more than a hundred syndicates, and its Lloyd's Lab exists to accelerate new insurance products. The Bank of England, founded in 1694 and now the UK's central bank, stands on Threadneedle Street.

Those institutions create a deep pool of specialist firms: managing agents, coverholders, claims adjusters, compliance consultancies, legal practices and technology suppliers, many of them small teams handling high-value work. The Barbican, an arts, learning and conference centre owned and funded by the City Corporation, adds a cultural and events economy to the district's business life.

Sectors

Sectors we build software for in City of London

Insurance, reinsurance and broking

Brokers, managing agents and coverholders juggle submissions, slips, endorsements and bordereaux across many counterparties. We build web tools that structure that data, track each risk through its life cycle and keep a clear record of who approved what.

Asset and wealth management

Investment managers and wealth firms need client reporting portals, onboarding with identity and suitability checks, and secure document vaults that present complex information clearly to clients.

Legal services

Commercial and disputes practices want matter portals, secure deal rooms, conflict-check workflows and time capture that feed their practice management system rather than duplicating it.

Fintech and regtech

Young firms selling into banks and insurers need a credible product with role-based access, audit logs and documentation that survives a procurement security review.

Conferences, culture and corporate events

Venues, arts organisations and conference organisers in the Square Mile need registration, badge printing data, sponsor management and attendee communication handled in one system.

Common requests

What firms in the Square Mile tend to ask for

Precision, security and evidence run through almost every brief from the City.

  1. Replacing spreadsheet-driven workflows

    Risk registers, bordereaux checks and approval chains moved from shared spreadsheets into a controlled web application with validation and history.

  2. Client portals with a full audit trail

    Clients see reports, sign documents and send instructions online, and every view, download and approval is logged.

  3. Onboarding and due diligence

    Know-your-customer steps, document collection and risk scoring combined into one guided process for clients and compliance staff.

  4. Internal tools that complement core platforms

    Focused applications around the edges of policy, trading or practice systems, connected through their APIs rather than bolted on by hand.

  5. Event and hospitality management

    Invitations, registrations, dietary requirements and seating for client events, with reporting for the relationship teams who host them.

Services

Software, app and web development services in City of London

Website design and development

For City firms, a website must look authoritative, load instantly and meet accessibility standards. We build sites that present expertise, people and regulatory information clearly, with enquiry routes that reach the right desk.

Custom software and web applications

We build controlled workflow, onboarding and reporting applications for insurers, brokers and advisers, with role-based access, maker-checker approvals and logs that compliance teams can rely on.

App development

Brokers and advisers moving between client meetings can use one installable web app on phone, tablet and laptop, with strong sign-in and no sensitive data left on the device.

SaaS product development

If you are building a fintech, insurtech or regtech product for City buyers, we help you ship a secure first version with tenancy, permissions and audit logging designed in.

E-commerce development

Most City firms do not sell goods online, but publishers, training providers and membership bodies in the Square Mile can sell subscriptions, courses and event places with proper invoicing.

API and system integrations

We connect CRM, policy administration, practice management, identity verification and accounting systems so data is entered once and reconciled automatically.

How we work

Remote delivery, run the way City firms expect

City teams work to tight diaries, so we keep our time with you short and purposeful. Discovery and reviews happen on video, every requirement and decision is written down, and the proposal, specifications, test environments and invoices are held in your client panel for anyone with the right permission to check.

A written proposal setting out scope, milestones and price is agreed before any build begins. We can answer supplier security questionnaires in writing, work within your information security policies and give each milestone a clear acceptance step that suits governance and procurement processes.

  1. A call about your brief

    A video call to understand the business, the people who will use the software and what has to change.

  2. A written proposal

    Scope, milestones and price in writing. Nothing starts until you accept it.

  3. Build in visible stages

    Each milestone is reviewed with you; progress, files and decisions stay in your client panel.

  4. Launch and look after it

    Go-live when you are ready, then maintenance and hosting if you want them.
