Gate Wall Studios LLC

An independent studio building its own games, and software for other businesses.

Gate Wall Studios develops and publishes original interactive entertainment, publishes its own business software, and designs and builds custom software for other companies under contract. All three are run by the same small engineering team, from design through to release and ongoing support.

Registered as Gate Wall Studios LLC Formed in Wyoming, USA Three revenue lines: games, our own software, services

What we do

Three lines of business, one engineering team

The company earns revenue in three distinct ways. They are kept separate in the accounts, and each is described below in the terms a reviewer would need.

1. Game development and publishing

We design, build and publish our own games for mobile and desktop. We own the intellectual property in what we make, and we release it directly to the public through the established app marketplaces.

  • How it earns: paid downloads and in-app purchases, collected by the platform (Apple App Store, Google Play) and paid out to the company on the platform's normal settlement cycle.
  • Who pays us: the platform operators, not individual consumers directly.
  • Current title: Eternal Bastion, in development.

2. Sealuno, our own software product

We develop, host and support Sealuno, accounting and invoicing software for small businesses. It is our own product, sold directly to businesses on a monthly subscription.

  • How it earns: recurring monthly subscriptions, charged per account with an additional per-user fee, after a free trial.
  • Who pays us: the subscribing businesses, billed monthly by card.
  • Status: in service, with customers on it today.

3. Custom software development

We build software for other businesses under contract: line-of-business applications, internal tools, integrations between systems a company already runs, and continued maintenance of what we deliver.

  • How it earns: invoiced work, billed by the hour or by fixed-price engagement against a written agreement, on ordinary commercial payment terms.
  • Who pays us: business clients, invoiced directly by the company.
  • Typical work: application development, systems integration, technical support and maintenance.

Our games

Eternal Bastion Coming soon

An action arcade game. Build your fortress, command your warriors and hold the line against endless waves of enemies.

Eternal Bastion will be the studio's first published title and is coming soon to iOS and Android. It is built and owned in-house: the code, the art and the design are the company's own work and remain its property.

Our software

Sealuno

Accounting and invoicing software for small businesses. Quotations, sales orders, invoices, inventory, purchases, bank reconciliation, time and billing, and reports in one place, for owners who need to run their books without running a finance department. It works as a point of sale and as wholesale software too, and because it is the accounting system as well, the sale and the books are the same act rather than two systems reconciled at month end.

Sealuno is built, hosted and supported by Gate Wall Studios LLC and sold directly to businesses on a monthly subscription. It is in service today, and the terms of service, privacy policy and data processing agreement published at sealuno.com are the company's own.

What it does

  • Quotations that become sales orders, then invoices
  • Inventory, batches and barcodes, moving with what is sold
  • Purchases, bills and what you owe by vendor
  • Bank registers, and reconciliation against the bank's own statement
  • Time and billing: a clock per client, at a rate frozen when it is logged
  • Payments taken several ways at once, in parts, or in another currency
  • Appointments, customers and vendors
  • Your own mailboxes, WhatsApp and Telegram, inside the app
  • 18 reports that tie back to the ledger, and a period lock to keep filed figures filed

How it is sold

  • Monthly subscription, billed per account
  • An additional monthly fee for each extra user
  • An optional cloud backup add-on
  • A free trial before any payment, no card required to start

Current pricing is published on sealuno.com.

Software services

Software built for the way a business actually runs

Contract engineering work for business clients, from a first conversation about the problem through to a delivered, supported system.

Application development

Software built to a client's requirements, where an off-the-shelf product does not fit the way the business works. Delivered, documented and handed over.

Systems integration

Connecting the systems a company already depends on so that data moves between them reliably instead of being re-typed by hand.

Maintenance and support

Continued care of software we have delivered: fixes, changes as the business changes, and help when something needs attention.

Technical consultation

Advice on how a system should be built or replaced, scoped as a piece of work with a written outcome rather than an open-ended arrangement.
