At a glance
3ANGLE CORP. is a New York software studio, founded in 2009, that trains AI models and builds AI platforms, mobile apps, SaaS products, eCommerce stores and custom business software. One senior team handles strategy, design, engineering and growth — the people who scope your project are the people who ship it.

What we do
From custom AI models to global commerce — one accountable team across strategy, design, engineering and growth.
We go beyond bolt-on AI features — we train and fine-tune custom models, build RAG, search and agent systems, and ship production-grade AI platforms like Catalyx.ai and InventaCloud.ai.
Native and cross-platform apps people actually keep on their home screen — fast, offline-ready and beautifully on-brand.
Multi-tenant platforms with auth, billing, dashboards and APIs — architected to scale and priced to be profitable.
Storefronts that convert — headless or platform-based, tuned for speed, merchandising and lifetime value.
Internal tools, portals and automations that replace spreadsheets and busywork — connecting the systems you already run.
We help neighborhood stores, restaurants, salons, contractors and family-owned businesses get online — professional business websites for a $1,500 flat fee and complete Shopify store setups for $2,500. Clear scope, transparent pricing, and no hidden fees.

Common questions
The questions we get asked most — answered plainly enough to be useful on their own.
3ANGLE CORP. is a New York software studio founded in 2009. We train and fine-tune AI models and build AI platforms, mobile apps for iOS and Android, multi-tenant SaaS products, eCommerce stores, and custom internal software. Strategy, design, engineering and ongoing growth all come from the same senior team.
We are based in New York, NY and work with clients across the United States. Our clients range from neighborhood businesses buying a $1,500 flat-fee website to global brands including Pantone, Trek Bikes, State Farm, Nutrafol, Foundry Lighting and Voyager Technologies.
We train them. Alongside LLM applications, retrieval-augmented generation (RAG), semantic search and AI agents, we train and fine-tune custom models, build the data and vector infrastructure behind them, and run the MLOps — deployment, monitoring, guardrails and cost control — on AWS. InventaCloud.ai and Catalyx.ai are AI platforms we built end to end.
Two packages have published flat fees: a Basic Business Website at $1,500 and a Shopify Store Setup at $2,500. Everything else — AI platforms, mobile apps, SaaS products, enterprise commerce and custom software — is scoped and quoted per project, because the price depends entirely on what the software has to do. You get a written proposal with the price before any work starts, and anything outside the agreed scope is quoted before it begins.

AWS for cloud and MLOps; Shopify and Shopify Plus, WooCommerce and WordPress, Magento and Adobe Commerce, and Salesforce Commerce Cloud (Demandware) for commerce; React, Next.js, Node and .NET for web; Swift, Kotlin, React Native and Flutter for mobile; and Lucee/ColdFusion and SQL for legacy and in-house systems. We also build custom Shopify apps, public and private.
Yes. Rescue and modernize is one of our four standard engagement models, alongside building from zero, embedding a senior design and engineering pod inside your team, and running and growing a product you already have. We regularly fix, refactor or replatform half-finished and inherited applications.
Both. Small and local businesses — restaurants, salons, contractors, retailers and family-owned firms — are served by flat-fee packages at 3anglecorp.com/small-business-websites: $1,500 for a professional business website and $2,500 for a complete Shopify store setup, with no hidden fees. The same team scales those clients into Shopify Plus, headless commerce and custom software when they outgrow the packages.
Four stages: Discover (stakeholder workshops, user research and a scoped plan with a defined measure of success), Design (interactive prototypes and a design system, validated before production code), Build (two-week agile sprints, each ending in a shippable, demo-able increment), and Scale (launch, measure and keep optimizing performance, conversion and cost). You see working software every sprint rather than a status report.
No, and no honest agency can. We build on solid SEO and accessibility fundamentals — Core Web Vitals, semantic markup, structured data and WCAG 2.1 AA — and we offer ongoing SEO as a separate service, but search positions, traffic and revenue are outcomes nobody can promise.
