Custom App Development
Mobile apps, progressive web apps, web applications, customer portals and internal tools built around a real product requirement.
Discuss an app →Product strategy, design, engineering and integration for apps, AI experiences and business software.

Bring us the concept, the existing product that needs work, or the operational problem that should be software. We can help define the product, design the experience, engineer the system, connect the services it depends on, and prepare it for real users.
Our own products are an active proving ground for the same disciplines: navigation, communications, AI, creator technology, document intelligence, payments, media, identity and connected product infrastructure.
When a supported product is ready for release, GGIRL can also help prepare its public launch and, where appropriate, distribution through the GGIRL App Store.
Focused services for new products, existing products and businesses that need technology to do more.
Every engagement starts with a defined scope. Deliverables, third-party costs, responsibilities and release requirements are agreed before development proceeds.
Mobile apps, progressive web apps, web applications, customer portals and internal tools built around a real product requirement.
Discuss an app →Assistants, workflow automation, knowledge systems and intelligent product features connected to the tools and data that make them useful.
Discuss AI →Concept definition, prototypes, MVP engineering, validation, testing and a practical path from an early idea to a usable product.
Build a product →Professional websites, product platforms, creator experiences, community surfaces and business-facing digital systems.
Build a platform →Rebuild aging interfaces, improve mobile behavior, convert web experiences to PWAs, strengthen architecture and add modern capabilities.
Modernize a product →Dashboards, workflow systems, operational tools and private software designed around how a business actually works.
Discuss business software →Payments, maps, communications, authentication, media, data services and external platforms connected into one reliable product.
Connect systems →Music, audio, video, media-production workflows, creator tools and the infrastructure needed to move creative work through a digital product.
Discuss creator technology →Product structure, interface design, user flows and interactive prototypes that make the build clearer before engineering expands.
Design the product →Ongoing development, maintenance and technical support, with scope and responsibilities agreed for each project.
Plan ongoing development →GPS-aware products, map experiences, routing interfaces, trail and field workflows, location context and mobility-focused product engineering.
Discuss location technology →Push-to-talk, voice messaging, presence, notifications and multi-device communication experiences designed around user permissions, privacy and reliable delivery.
Discuss communications →Document ingestion, grounded question answering, page citations, research workflows and evidence-linked knowledge systems for education, operations and professional use cases.
Discuss document intelligence →The work changes by project. The discipline does not.
Velvet products give GGIRL a working environment for solving the same kinds of product, infrastructure and user-experience problems we take on for clients.
