## Where most teams are

An AI feature that works in a demo is the easy part. Getting it right on real data, at a cost and speed that work for real users, is the job. Our engineers join your team on a retainer and do that work every week, in your codebase.

The AI demo works, production does not → AI tested on your real data before launch

Answers are wrong often enough to hurt → Answers grounded in your own content

LLM costs grow faster than usage → Model, cost and speed chosen per task

Nobody on the team has shipped AI → A senior AI engineer, month to month

## What our AI developers do

### Natural language to answers

Search, Q&A and English-to-SQL over your own data, with every query checked before it runs, so users ask in plain words and get answers they can act on.

### AI on top of messy signals

Models that read your product's raw activity, such as events, messages or logs, and flag what needs attention before a person would spot it, with every alert traceable.

### Chat and voice products

Chat and voice assistants with memory, guardrails and a hand-off to a person, built so the conversation stays useful long after the novelty of the first five minutes.

### Generated content users trust

Generated quizzes, summaries and drafts with quality checks built in, so what your users see is correct and useful, not just fluent, and a weak output gets caught first.

## How it works

1. 01

### Pick a tier

Part-time, dedicated or embedded, from $4,000 a month. Tiers differ in hours and in how closely we work with your team.
2. 02

### Start with what pays off

A senior engineer looks at your product and data, and agrees with you which AI feature to build first and how you will know it works.
3. 03

### Ship and measure every week

Features, evals, cost and speed work. The engineer doing the work is the one on your calls. Change tier or stop any month.

Starting at $4,000/mo

Part-time from $4,000/month, month to month. Building a whole AI product? See our [AI development company](https://zeroic.in/ai-development-company) page. Not sure where AI pays off? Start with an [AI audit](https://zeroic.in/services/ai-audit) (from $1,000).

[Talk to an AI developer](https://zeroic.in/book?service=retainers)

We came to Zeroic for one fixed-scope build and never left. Shankar Prasad built the AI into WordUp and kept finding more worth shipping - we doubled our retainer hours inside the first month. He tells us what's worth building before he builds it.

FAQ

## Frequently asked questions

How much does it cost to hire an AI developer?

Our retainers start at $4,000 a month for the part-time tier, month to month. Dedicated and embedded tiers add more hours. Prefer a fixed scope? We also do fixed-price projects, and audits from $1,000.

Which AI models and tools do you use?

OpenAI and Anthropic Claude models, open models where they fit, LangChain and LangGraph for agents, and embeddings and vector databases such as pgvector or Pinecone, chosen per task by quality, cost and speed.

Can you add AI to the product we already have?

Yes. Most of our AI work is inside products that are already live. The engineer works in your codebase and ships alongside your team.

How do you stop the AI giving wrong answers?

By grounding answers in your own data, testing them against real examples before launch, and checking quality as you go. Where a simple rule does the job better than a model, we use the rule.

Do we own everything you build?

Yes, 100%. You own the code, prompts, data pipelines, docs and credentials.
