Platforms
What We Build
Software that has to run a business, not a demo. Every engagement covers the full path from architecture to launch to operations — and the marketing and hosting that keep it growing afterwards.
Web Applications & Platforms
Multi-tenant platforms, marketplaces, SaaS dashboards, and customer portals. Authentication, payments, APIs, admin tooling, and database design built for the load you expect after launch.
Mobile Apps
iOS and Android apps — native or cross-platform — connected to the same backend as your web product, with store submission, push notifications, and offline handling included.
AI & Machine Learning
LLM features, retrieval augmented generation, computer vision, and predictive analytics — trained, integrated, and monitored in production rather than left in a notebook.
Cloud & Managed Hosting
Containerized deployments, CI/CD, SSL, CDN, backups, and monitoring. We host static marketing sites and multi-service platforms on the same infrastructure we build them on.
SEO & Growth
Technical SEO, structured data, content, paid search, and conversion rate optimization — run by the team that wrote the code, so the fixes actually ship.
IP-Based Financing
Use your intellectual property as working capital to fund the build, so a software project does not have to drain operating cash in a single quarter.
How We Compare
Every option has trade-offs. Here is the honest version of where a fixed-scope studio fits.
723 Studios
Fixed-scope quote agreed before work starts. Senior engineers across web, mobile, and AI. A 6-month post-launch bug-fix guarantee. Hosting, monitoring, and marketing handled by the same team that built it.
Fixed price
Post-launch guarantee
Full stack
Typical Agency
Retainer or hourly billing where the total moves as scope drifts. Work is frequently handed to junior staff. The relationship usually ends at launch, leaving hosting, SEO, and support to somebody else.
Retainer
Handoff at launch
Freelancers / Offshore Bench
Lowest day rate, but coverage is usually narrow — one developer rarely spans web, mobile, AI, and cloud. You own the coordination, the QA, and the post-launch risk.

Frequently Asked Questions
Straight answers about scope, cost, timelines, and what happens after launch.
What does 723 Studios do?
723 Studios is a software development agency. We design, build, and operate custom web applications, mobile apps, AI and machine learning systems, and the cloud infrastructure behind them.
How much does a custom software project cost?
Every project is quoted as a fixed price after a short scoping call, so the number matches the work instead of an hourly estimate that moves. Request a free quote and you will get a written, fixed-scope proposal.
How long does a project take?
The delivery schedule ships with your fixed-scope proposal and is delivered in reviewable milestones, so you always know what is next and when.
What is the 6-month post-launch bug-fix guarantee?
For six months after launch, any bug inside the delivered scope is fixed at no additional cost to you.
Do you build AI features?
Yes. We have shipped AI image analysis for automotive damage assessment, AI music generation and personalized streaming, and privacy-first routing. We build LLM features, computer vision, and predictive analytics into products that run in production.
Can you host and maintain the product after launch?
Yes. Managed hosting, monitoring, backups, and deployments are available for both static marketing sites and complex multi-service platforms. See hosting plans.
What is IP-based financing?
IP-based financing lets you use your intellectual property as working capital for a software project, so you can build now and spread the cost instead of paying everything up front. Apply for financing.
How do we get started?
Send your requirements through the free quote form or the contact page. We review scope, ask the questions that matter, and send back a fixed-scope proposal with a schedule.
