Custom software & internal tools
Operations platforms, client portals, approval queues and the line-of-business systems the twelve SaaS subscriptions on your invoice still do not cover.
We build the software New York companies cannot buy off the shelf: operations and client portals, internal tools, AI agents and integrations, and first products for startups. We are a UK-registered company working remotely with no New York office, and we schedule calls in your Eastern Time working hours rather than leaving you a handover note overnight.
Thanks, that’s with us.
A senior engineer reads every enquiry and will reply as soon as they can.

Technologies we build with
Quick answer
It builds software for one company rather than selling one product to everybody. In New York that usually means the layer around a regulated core: onboarding, reconciliation, reporting and control tooling for a firm in the Financial District or Midtown; editorial, rights and campaign systems for a media or advertising business; intake, scheduling and records tooling for a health system or an ambulatory network; leasing, deal and building-operations software for owners and brokerages; and first releases for startups in Flatiron, Brooklyn and Long Island City who need something real in front of users before the next round of planning.
Being direct about who we are: SpiderHunts Technologies Ltd is registered in the United Kingdom, with a registered office in London and a remote team. We have no New York office, no New York staff and no coworking desk in Manhattan that we would call a headquarters. We work with New York companies remotely, the way most distributed engineering teams already do, and we would rather you knew that on the first call than after a procurement review. The wider American picture is on our United States page; the detail of how a build is actually run is on the custom software development page.
The time-zone setup is the part New York buyers usually check first, and it is the one we would defend. Our team schedules calls in your working hours, so standups, demos, design reviews and decisions all sit inside your Eastern Time working day. Because our day starts long before yours, something handed over in your afternoon is usually waiting for you the next morning.
What we build
The engineering work you would otherwise give an in-house team, built around your workflow and released into your own cloud account.
Operations platforms, client portals, approval queues and the line-of-business systems the twelve SaaS subscriptions on your invoice still do not cover.
Onboarding and verification flows, reconciliation and reporting views, exception queues, and audit trails that hold up when an examiner or an auditor asks how a number was produced.
Content workflow with real review and approval, rights and licensing tracking, asset management with metadata and search that works, and campaign reporting that consolidates a dozen ad platforms into one number a client will believe.
Agents that triage, research, summarise, draft and prepare work for a person to approve, running inside your own tools with guardrails, prompts and logs you control.
AI added to Salesforce, HubSpot, NetSuite, Zendesk and your own database through their APIs: document extraction, semantic search over an archive, summarising for research and editorial teams.
Scoring, forecasting, classification and anomaly detection trained on your own history, deployed with monitoring and retraining rather than left in a notebook.
First releases and multi-tenant platforms for New York software companies: authentication, billing, admin, partner APIs and enough analytics to learn something from launch.
US-region infrastructure as code, least-privilege IAM, encryption, secrets management, CI/CD with review gates and scanning, and logging your security team can actually query.
Enterprise builds
What changes when the buyer is a large organisation with a security team, a procurement process and systems that are older than the people running them.
Enterprise software development is custom software built to the standards a large organisation already holds its own systems to: single sign-on through the company directory, role-based access, audit logs, integration with core systems such as the ERP, CRM, ledger or custodian, and a handover your own engineers can support. For a New York company it usually sits around a regulated core rather than replacing it, and the engineering is shaped as much by the security review and the integration work as by the screens people see.
We take on that work remotely, with the same honesty as everywhere else on this page: no US entity, no New York office and no SOC 2 report of our own. If your procurement policy requires any of those, we will say so on the first call rather than three weeks into vendor onboarding. If it does not, the table below is how we handle what enterprise buyers usually ask for.
| What enterprise buyers ask for | How we handle it |
|---|---|
| Single sign-on | Sign-in through Okta, Microsoft Entra ID or Google Workspace over SAML or OpenID Connect, with roles mapped from your directory groups |
| Access control and audit | Role-based permissions, plus a log of who viewed or changed what that can be exported for an auditor or an examiner |
| Integration with core systems | APIs, message queues or scheduled file exchange with your ERP, CRM, ledger, custodian or EHR, including older systems through whatever interface they expose |
| Data migration | Mapped, scripted and rehearsed in a test environment, with record counts and reconciliation reports before the real cutover |
| Vendor security review | We complete your questionnaire, explain exactly how our access works, and work to your vendor policy and your master services agreement |
| Reliability at volume | Load tests sized to the volumes you give us, monitoring and alerting, and runbooks for the failures that matter |
| Handover | Code, infrastructure as code, documentation and runbooks in your repositories, so your team or another firm can support it |
Buyer’s checklist
Six checks that separate a firm that will ship from one that will only present well. They apply to us as much as to anyone else on your shortlist.
Choose on how the firm works, not on the size of its client logos. A good custom software development company in New York, local or remote, will scope against your actual workflow, put code in your repository from the first week, show working software every sprint, quote against a written scope with exclusions, and leave you owning the code and the cloud account. The six checks below take an afternoon and save most of the expensive surprises.
Describe who does what today, which systems are involved and where it breaks. Firms that quote from a feature list alone are guessing, and the guess usually lands in your change requests later.
If your team needs engineers in the room most days, hire a local New York firm; we are a remote team and would tell you the same. If video calls in your working hours suit you, the field of good options gets much wider.
The answer should be you: code in your GitHub or GitLab, infrastructure in your own AWS, Azure or Google Cloud account, and access you can revoke. Be wary of anything hosted only in the vendor’s account.
How often will you see working software? Who joins the calls? Can you read the repository and the ticket board as work happens? Two-week sprints with a live demo each time are a sensible default.
Give every firm the same written brief and ask each quote to list scope, exclusions, assumptions and how changes are priced. A quote that is cheap because it leaves out integration and testing is not cheap.
Read reviews on platforms the firm does not control, and ask to speak to the engineers who would build your project rather than only to sales. Their questions on that call tell you a great deal.
Why it matters
New York teams are rarely short of tools. They are short of a system: a dozen subscriptions, four of which nearly do the job, and an operations person quietly holding it together with exports and a spreadsheet.
Have a New York project that keeps slipping down the roadmap?
Tell us the workflow, the systems it touches and who uses it. We will say whether buying beats building, and what a first build would realistically cost.
Examples
Typical problems New York teams bring to us, and the software that addresses them. Illustrative examples of what we build, not client results.
An application flow that collects documents, calls the identity and entity verification vendors you already licence, records every check and decision, and sends only unclear cases to an analyst.
Aim: a consistent, documented decision on every application
One view built from custodian statements, your ledger and market data feeds, with breaks raised the day they appear and every figure traceable back to the record it came from.
Aim: month-end read from live data instead of rebuilt by hand
Commissioning, review and approval in one place, with rights and licence windows tracked against each asset and campaign reporting pulled from the ad platforms into a single client-facing view.
Aim: what can run, where and until when, answerable without an email thread
Intake forms and document capture feeding a clinical operations view, built with encryption, role-based access and audit logs, and exchanging data over HL7 v2 or FHIR with the systems already in place.
Aim: less re-keying between systems, with an access trail a privacy officer can review
Deal pipelines for a brokerage, tenant and owner portals, and a building operations view that keeps inspection, filing and reporting deadlines visible instead of buried in someone’s calendar.
Aim: deadlines and documents surfaced before they become a problem
Authentication, the one workflow that proves the idea, billing, an admin view and the analytics you need to learn from real users: built so the second release is not a rewrite.
Aim: real user feedback before the rest of the runway is spent
How we work
Short stages with a clear output each time, arranged so the Atlantic is never the reason something waits a day.
Thirty minutes in your working hours on the problem, the systems involved and what ‘done’ looks like. We ask awkward questions, and we will say if buying beats building. You get a written quote with scope, exclusions and an estimated timeline.
We agree which cloud account and US region the work runs in, who grants access to which systems, and which privacy and security obligations apply, the SHIELD Act, your DFS programme, HIPAA safeguards, your own vendor policy, before any code is written.
Work lands in your repository from the first week. There is a written update every day and a live demo in your Eastern Time working hours, on a call you can invite your stakeholders to. Priorities can change between sprints.
Your custodian, your ad platforms, your CRM, your ledger, your EHR. Most project risk lives here, so we hit it early rather than in week ten, and automated tests and scans run in the pipeline throughout.
Deployment into your own cloud account, with code, documentation, infrastructure definitions and runbooks in your repositories so your team or another 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?
We would rather tell you to buy a product or hire locally than take on a project that will not work across an ocean.
Make an informed choice
Buying is often the right answer, and we will say so on the first call. Custom earns its place when the process is the product.
| Factor | Buy a SaaS product | Hire in New York | Build it with us |
|---|---|---|---|
| Fit to your workflow | You bend to the product | Whatever you can build once staffed | Built around the workflow as it is |
| Time to something usable | Immediate, if it fits | Months, once hiring is done | Typically 4–8 weeks for a first release |
| Cost shape | Per seat, rising with headcount | Salary, benefits and recruitment | A quoted build, then hosting and changes |
| Where the data sits | The vendor’s region and terms | Wherever you choose | Your own account, in a US region |
| Overlap with your day | A support ticket queue | The whole day, in the office | Your working hours, every working day |
| Evidence for an audit | Whatever the vendor exposes | Whatever you build | Built to the obligations you name |
| What you own at the end | A subscription | Everything | Code, documentation and infrastructure |

FAQ
Starting with the question most agency pages quietly skip.
Still have a question?
Ask us directly. A senior engineer reads every question.
Ask about your projectNo. SpiderHunts Technologies Ltd is registered in the United Kingdom, with a registered office at 182-184 High Street N, Office 14607, London E6 2JA, and its team works remotely. Those are our only two locations, and neither is in New York. There is no US entity, no New York staff and no rented desk in Manhattan that we would describe as a headquarters. We say so plainly because some buyers need a US-domiciled supplier, and it is better to know that on the first call than three weeks into a procurement review.
No. Discovery, sprint demos, architecture reviews and support all happen over video and shared tooling, inside your Eastern Time working hours, and we have worked with US clients this way since 2020. Where a project would normally open with a full-day on-site workshop, we run it as two or three shorter video sessions across consecutive days, which holds attention better on video than one long day ever does.
New York runs on Eastern Time, five hours behind London for most of the year: the friendliest transatlantic gap there is, and it only narrows to four hours for the couple of weeks each spring and autumn when the two countries change their clocks on different dates. Our team schedules calls in your working hours, so standups, demos, design reviews and decisions all sit in your Eastern Time working day, and we tell you in advance who will be on each call. Because our day starts before yours, work handed over in your afternoon is usually waiting for you the next morning.
Projects are quoted in pounds sterling and invoiced in US dollars at the rate agreed in the quote, so both sides know the dollar figure before work starts. Invoices are raised by SpiderHunts Technologies Ltd against a written scope with milestones, and we can complete a W-8BEN-E for your accounts payable team. Payment by ACH, wire or card. Your legal team is welcome to work from your own master services agreement, and we are used to vendor onboarding portals and security questionnaires.
In your accounts, not ours. We deploy to the US region you choose, commonly AWS us-east-1 in Northern Virginia, Azure East US or Google Cloud us-east4, inside your own cloud organisation, and code goes to your GitHub, GitLab or Azure DevOps. For latency-sensitive work there is an AWS Local Zone in New York City itself. Engineers get named, least-privilege access you can revoke at any time, and we keep production data out of development environments unless you specifically ask otherwise.
Yes, as a design goal. The SHIELD Act expects reasonable administrative, technical and physical safeguards for the private information of New York residents, and it follows the data rather than the company, so it applies to systems holding that information wherever they run. We build the technical half: encryption in transit and at rest, access controls and least privilege, secure disposal and retention rules, logging of who saw what, vendor and integration review, and the detection and reporting hooks a breach-notification process needs. The administrative and physical safeguards, the policies and any notification decision belong to your organisation and its counsel. We do not certify anything and we will not describe a build as SHIELD Act compliant.
If your firm is licensed by the New York Department of Financial Services, Part 500 shapes a lot of the engineering: multi-factor authentication, access privilege management and periodic review, encryption of nonpublic information, audit trails that can reconstruct a financial transaction, asset inventory, secure development practices, and incident reporting on a tight clock. We build to those controls and produce the evidence your programme and your CISO have to be able to show: exportable, not screenshotted. We are not a DFS-covered entity, we do not certify anyone’s programme, and where we count as a third-party service provider we will complete your due-diligence questionnaire and work to the terms your policy requires.
No, and we will not claim to be. We hold no SOC 2 report of our own. What we can do is build systems that support the controls your auditor will test: change management with peer review, access reviews, logging, encryption, backup and restore, and evidence that can be exported rather than assembled by hand the week before fieldwork. If you are preparing for your own SOC 2 audit, that is exactly the sort of engineering work we take on.
We build to the technical safeguards HIPAA expects, encryption in transit and at rest, unique user identity, role-based access, automatic logoff, integrity checks and audit logs of who opened which record, and we exchange data with the systems already in place over HL7 v2 or FHIR, including connections to a regional health information organisation where you have one. We will not call the result HIPAA compliant, because compliance covers your policies, training, contracts and physical controls as well as the software. Whether a business associate agreement is needed, and what it should say, is a decision for your counsel. Our healthcare page covers the sector in more depth.
The problems here are volume and velocity rather than regulation. Typical builds are editorial and content workflow systems with review and approval that people will actually use, rights and licensing tracking so anyone can answer what may run where and until when, digital asset management with metadata and search that works on a large archive, campaign and client reporting that consolidates a dozen ad platforms into one number, and custom layers where an off-the-shelf CMS has hit its ceiling. AI helps most with extraction, tagging, semantic search across an archive and first-draft summarising: always with an editor approving before anything publishes.
You get a written quote after a free scoping call. As typical ranges from our service pages: a focused internal tool or first release is £8,000–£20,000, a business web application £20,000–£45,000, a platform or modernisation £45,000–£80,000+, a single-purpose AI agent £5,000–£12,000, and a focused machine learning model £8,000–£25,000. Those are quoted in pounds and invoiced in dollars at the agreed rate. Cloud hosting and third-party licences are separate and stay in your own accounts. Change requests are quoted before they are built.
We work in English, in writing as well as on calls. New York is one of the most multilingual cities in the world, so consumer-facing products here usually need at least Spanish and often more: we build interfaces so text, dates, currency and number formats are translatable, and so adding a language later is a content task rather than a rebuild. We do not supply translation as a service, your team or your translator provides the wording, and we make sure the product carries it correctly, including in the places people forget, such as emails, receipts and error messages.
Yes. Most of what New York teams ask us for is a web application: client and investor portals, operations dashboards, approval queues, reporting views and multi-role business applications, usually built with React or Next.js on the front end and Python or Node.js behind it, deployed into your own US cloud account. Customer-facing sites and web applications are covered in more depth on our web development page; the pricing on this page applies to New York projects.
Yes, for the engineering. We build to enterprise expectations: single sign-on through your directory, role-based access, audit logs, integration with core systems, rehearsed data migrations and documented handover. What we cannot offer is a US entity, a New York office or a SOC 2 report of our own, so if your procurement policy requires any of those we will say so on the first call. The enterprise section above sets out how each requirement is handled.
Yes, and they are often the best first project. Typical internal tools are approval and exception queues, admin panels over an existing database, reconciliation and reporting views, and small operations systems that replace a shared spreadsheet. A focused internal tool is typically £8,000–£20,000 and 4–8 weeks to a first working release, quoted against a written scope after a free call.
Start with a written description of the workflow and the systems involved, then decide whether you need engineers on site; if you do, choose a local firm. After that, compare firms on who owns the code and cloud account, how often you will see working software, whether quotes list scope, exclusions and change pricing against the same brief, and what independent reviews say. Ask to meet the engineers who would build the project, not only the sales team.
