Custom software development company in San Francisco

No. We have no US entity, no US office and nobody on the payroll in the United States. We are a UK-registered company with a registered office in London, and the whole team works remotely with Bay Area clients. Calls, demos and reviews are scheduled in your Pacific Time working hours and held by video.

Calls, demos and design reviews are scheduled in your Pacific Time working hours, not ours. The team works remotely and arranges its day around yours, so an afternoon review in San Francisco is a normal booking rather than a favour. Written updates arrive daily. We do not promise round-the-clock cover or instant replies; we agree a meeting rhythm at the start and keep to it.

Yes, within limits. We contract as SpiderHunts Technologies Ltd, a UK company, and invoice in US dollars. Terms your counsel expects, such as IP assignment, confidentiality and security obligations, are familiar, and we are happy to work from your own agreement. Anything that requires a US entity, US-person staff or a US address for service is something we cannot provide, and we say so early.

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 rather than ours.

In your accounts, not ours. San Francisco teams commonly choose AWS us-west-1 in Northern California, AWS us-west-2 in Oregon, Azure West US or Google Cloud us-west1, all on the West Coast. Code goes to your GitHub, GitLab or Azure DevOps. Engineers get named, least-privilege access you can revoke at any time, and production data stays out of development environments unless you ask otherwise.

They shape the design where the law applies to you. The California Consumer Privacy Act, as amended by the CPRA, gives California residents rights to know, delete and correct their personal information, to opt out of its sale or sharing, and to limit use of sensitive data such as biometrics. So we build data inventories, request-handling workflows, consent records and deletion jobs that actually run. Whether and how the law applies is for your counsel.

Yes. Fintech teams often have a polished product and a back office held together by spreadsheets, so that is where we work: ledgers that balance, reconciliation against payment providers, onboarding and KYC workflow, dispute handling and regulatory reporting. We are software engineers, not a money transmitter, a bank or a compliance consultancy. Your compliance team defines the rules; we build systems that enforce them with role-based access, audit logs and reviewable data lineage.

Yes, on the systems around the science. Biotech companies in South San Francisco and across the Bay Area often outgrow spreadsheets for sample and assay tracking, inventory and study records before they are ready for a large platform. We build that layer and integrate it with your LIMS or electronic lab notebook. Where GxP expectations apply, your quality team sets the requirements and we build audit trails and validation evidence to match.

That is usually what we recommend. Growth-stage San Francisco companies tend to run finance on NetSuite or a similar ERP that is now embedded in billing, revenue and reporting, and a rip-and-replace is where most of the money and most of the risk goes. We build the layer above it instead: metering, approvals, reconciliation and reporting that reads live data. Our note on integrating with an ERP rather than replacing it covers the approach.

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 saw which record. 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 is a decision for your counsel. Clinical integration is normally through HL7 or FHIR interfaces your own team controls.

You get a written quote after a free scoping call. As typical ranges from our service pages: an internal tool or MVP is £8,000–£20,000 over 4–8 weeks, a business web application £20,000–£45,000 over 2–4 months, and a larger platform or modernisation £45,000–£80,000+ over 3–6 months. A focused machine learning model is £8,000–£25,000 and a single-purpose AI agent £5,000–£12,000. Those are quoted in pounds and invoiced in dollars; cloud and third-party licence costs are separate and stay in your own accounts.

No. We are fully remote, so meetings and day-to-day work happen over video, Slack or Teams and a shared board. Where a project would normally open with an on-site workshop, we run it as two or three shorter video sessions in your Pacific Time working hours instead, which works better over video than one long day does.
