Custom AI development
AI development services built around your businessnot around a generic tool.
We provide AI development services for companies whose needs off-the-shelf tools don't meet. We build custom AI on your data and tools, test it on real work, and you own the code, prompts and data.

Results
What custom AI looks like in real companies.
Five systems from our AI application development services, with the numbers that changed.
Government contracting
Proposals cut from 60 hours to under one.
A federal contractor bidding on $10M+ contracts could only submit 3–4 proposals a quarter, because each one took about 60 hours to assemble by hand. We built an AI workflow that pulls past performance, checks compliance and formats to spec, so the team now submits 12+ a quarter.
<1 hper proposal, down from ~603xproposal capacity+23%win rateSaaS / Software
85% of support tickets resolved by AI.
A SaaS company with 50,000+ users had its best agents answering the same questions all day, and customers waited two hours for a reply. We built an AI assistant trained on their past tickets that answers instantly and hands complex cases to a person with full context.
1,200+agent hours back every month<5 sfirst response, down from 2 h+45%customer satisfactionInsurance
Claims processed 75% faster.
A regional insurer's adjusters spent 70% of their time on routine claims, so every claim took 15 days. We built an AI that reads the documents and photos, checks the policy and recommends a decision, so adjusters only handle the complex cases.
600+hours back every month99.5%decision accuracy+30%capacity, no new hiresE-commerce / D2C
Every lead contacted in under 20 seconds.
A home goods brand spending $40K a month on ads took 6–12 hours to reply to new leads, so many bought elsewhere. We built an AI system that replies by SMS, email or voice call within 20 seconds, day or night.

Manual invoice entry eliminated.
A boutique law firm's paralegals spent a quarter of their time retyping invoices, so billing ran late. We built an AI assistant that reads every invoice, matches it to the right case in Clio and syncs it to QuickBooks.

The problem
AI built without care gets expensive.
99%
of organizations surveyed reported financial losses from AI-related risks.
64%
suffered losses of more than US$1 million.
Buying a generic tool is easy. Making AI work safely on your data and processes is where projects stall or go wrong.
- Generic AI tool: Works on generic examples and misses how your business actually runs.Custom artificial intelligence solutions: Built on your own data, rules and processes from the start.
- Generic AI tool: Sits beside your systems, so people copy results by hand.Custom artificial intelligence solutions: Connected to the CRM, inbox and tools your team already uses.
- Generic AI tool: You rent it, and you can't change how it behaves.Custom artificial intelligence solutions: You own the code, accounts, prompts and data from day one.
- Generic AI tool: Tested on demos, then surprises you on real work.Custom artificial intelligence solutions: Tested end to end on real work before anything goes live.
Custom means it fits your work, not the other way around.
Is it time?
When custom AI beats an off-the-shelf tool.
Signals you need this
- A packaged tool covers part of the job but not the steps that cost you most
- The work depends on your own documents, data or rules
- Your team copies results between tools by hand
- You need AI inside the software you already run
- You want to own the system instead of renting it
When not to invest yet
- A ready-made tool already does the job well
- You only want a chatbot on your site and nothing else
- You want a slide deck instead of a live system
What you get
Custom AI development services, idea to system.
- A map of the processes worth building around, with the hours and dollars each one costs you
- A roadmap ranked by payback, so you know what to build first and what to skip
- A fixed-price proposal with exact scope and timeline, before anything starts
- Assistants and agents built into your CRM, inbox, phone and the tools you already use
- Document and data pipelines that read, check and route the work your team does by hand
- Testing end to end before launch, so nothing goes live until it works without errors
- Team training and documentation, with everything we build yours to keep
How it works
The Payback Loop. Five steps. Each build pays for the next.
We don't start with the AI. We start with the money.
Consulting
We find the manual work in your company and how many hours each task eats every week.
Process mapConsulting
We put a dollar figure on each process and rank them by payback. You see what to automate first, and what to leave alone.
AI roadmap, ranked by paybackImplementation
We build the first system on the tools you already use. Nothing new for your team to learn.
A working systemImplementation
We test it end to end before launch. It doesn't go live until it works without errors.
Tested, system liveSupport
The first build pays back fastest, so its savings fund the next one. Back to the map, and we keep every system running.
Monthly support (optional)
↺ Back to Map
Consultancies stop at the roadmap. Freelancers build without one. The loop only works when one team runs all five. You approve, we execute: about an hour a week from you.

FAQ
Questions about AI development services.
- AI development services, sometimes called AI software development services, design and build AI systems around a company's own data, processes and tools: assistants and agents, document pipelines or AI features inside software you already use.
- Generative AI development services, also called LLM development services, build systems on large language models that read, write and reason over your content, such as drafting replies or answering questions. We build them on your tools and test them on real work.
- Hiring means recruiting, managing and keeping an AI team, and the median software developer earned $135,980 in 2025. A custom AI development company builds, connects and maintains the system for a fixed price, so you don't need a technical team.
- MIT research found only 5% of organizations reached production with enterprise AI tools. Most failed on brittle workflows and poor fit with daily operations, which is why we build on your processes and test on real work first.
- Yes. NIST calls confidently stated but false output confabulation. We test on your real documents before launch and keep a person in the loop for decisions that matter.
- You do. Everything we build is yours: code, accounts, prompts and data, from day one. Optional monthly support keeps it running, month to month, so you are not locked in.
- Partly. Machine learning development services train models on your own data to predict or classify. Many business tasks today fit large language models better. The right choice depends on the job and is part of the scope agreed before anything starts.
- The roadmap takes 1 to 2 weeks. Your first system is usually live in 14 to 21 days, and a full system takes 6 to 8 weeks. You get a fixed-price proposal first.
