Custom AI models, generative AI features and RAG pipelines for Illinois businesses, built by engineers who ship production software, with BIPA and CCPA-aware data practices from the first sprint.
Quick answer
Quick answer: Apptechies is an AI development company serving Illinois businesses with custom machine learning models, generative AI features and RAG pipelines, with BIPA and HIPAA-aware data handling built in from day one, not a compliance checklist applied before launch.
Selected work

Security by design
An AI model is only as trustworthy as the data pipeline feeding it. Every engagement starts with the same security baseline, covered by our compliance and security practices rather than a checklist applied right before launch.
Encryption at rest and in transit for all training and inference data
Role-based access control scoped to the smallest team that needs it
Versioned data pipelines so any model output is traceable to its source
Independent code review before any model reaches production
AI capabilities
From intelligent applications to production-ready AI infrastructure, we build solutions around the way your business operates.
Client stories
Trusted partnerships built through strong engineering, clear communication, and solutions that deliver real business value.
โThe AI-powered fitness platform Apptechies developed integrates personalized workout plans, nutrition tracking, and real-time progress monitoring in one beautiful app. Their technical execution has been exceptional.โ

Real tools our engineers use in production, selected around the requirements of each AI system rather than a fixed technology stack.
AI readiness
Compliance & privacy
Illinois has one of the strictest biometric privacy laws in the country. Any computer-vision or biometric AI project gets scoped against it during discovery, not as an afterthought.
BIPA-aligned consent and retention policies for any facial-geometry or biometric data
HIPAA-aware architecture for healthcare AI clients
CCPA-aware data handling for clients operating across multiple states
SOC 2-aligned engineering practices for access control and audit logging

Why Apptechies

8+ years building software that has to work in production, not just perform well in a notebook.
Every model gets containerised inference and monitoring.
Biometric-adjacent projects get consent and retention-policy review before a pixel of image data is stored.
CCPA and SOC 2-aligned practices scoped during discovery.
Recognition

Technology stack

Identifying the single highest-leverage AI use case first.
Assessing what data exists and what needs cleaning.
Hosted API, fine-tuned model, or a grounded RAG pipeline.
A working prototype against real data within the first sprints.
Wiring the model in with rate limits and validation.
Accuracy, latency and bias testing against real data.
Containerised deployment with ongoing drift monitoring.
Straight answers about AI development costs, timelines, model choices, data security, and working with our team in Illinois.
Custom models, generative AI features, RAG pipelines, AI chatbots and process-automation tools, matched to your product's actual data and workflow, not a generic off-the-shelf wrapper around a public API.
A focused AI feature typically runs $25,000-$70,000. A full generative AI product with multiple integrations can run $150,000 or more. We scope against your actual requirements after a discovery call.
Any project touching facial geometry, fingerprints or other biometric identifiers gets an explicit consent flow and a documented retention and destruction schedule reviewed during discovery. BIPA carries a private right of action, so this is not optional groundwork.
Yes. Route optimisation, demand forecasting and warehouse computer vision are a regular part of our work.
Our US headquarters is in Austin, Texas, with additional offices in London, UK and Mohali, India. We serve Illinois clients remotely with strong Central-time overlap and are happy to meet in person when useful.
A focused MVP typically takes 6 to 10 weeks. A full generative AI product with multiple integrations usually runs 16 to 24 weeks.
Yes, we are happy to sign an NDA before any detailed discussion of your data, business logic or systems.
Ask to see AI products the team has actually shipped to production, not just a prototype, then compare how each proposal handles data privacy, model evaluation and what happens after launch, rather than just the headline price.
We scope the specific use case, give an honest recommendation on whether prompting, fine-tuning or a full RAG pipeline fits, build and evaluate against real questions your users will ask, then deploy with monitoring rather than treating launch as the finish line.
An off-the-shelf AI tool can work when your use case is close to standard, like a generic support chatbot. Custom development earns its cost once you need the model grounded in your own data or evaluated against your own accuracy bar.
Yes, that is one of our most common engagements. We typically wire in a hosted model behind a RAG pipeline grounded in your own documents, so answers stay accurate to your business rather than generic.
Encryption at rest and in transit, role-based access control scoped to the smallest team that needs it, and versioned data pipelines so any model output is traceable to its source data.
Yes. You can hire an AI developer to work inside your existing team and codebase on a dedicated basis, or we can run the full project as a self-contained team depending on how you want to staff it.
You own the source code, trained model artifacts, and documentation delivered under the engagement. We are happy to sign an NDA before any detailed discussion of your data, business logic or systems.
