The ranking, entry by entry

1 LeewayHertz

Best for companies that want a firm focused on generative AI and agents

LeewayHertz ranks first because its stated work matches this question most closely. Its services cover AI strategy, AI agent development, machine learning, data engineering and software design, and it offers three engagement models, a dedicated development team, team extension and project-based work. The site shows The Hackett Group as its parent company, which will matter to buyers who want a firm with a larger organization behind it.

Watch for. No rates are published, and the pages we read give no head office address or headcount. Ask who would staff your project and where they are based.

2 Black Badger Software Solutions

Best for companies of 50 or more tying AI to their operations systems

Black Badger publishes this guide, so weigh this entry accordingly. We rank ourselves second, for a specific kind of buyer. We build AI tools that use the operations data a company already has, and we come to that from years of implementing and migrating business platforms before we moved to custom systems. We are based in Clearwater, Florida. You own the code and every account, and each build starts with discovery and a written scope.

Watch for. We do not publish a price. A written scope gives you the number, and we will say so if a product would serve you better.

Based in
Clearwater, Florida, United States After launch you pay running costs such as hosting, database and email. There are no licenses, so adding a person adds no fee.
Main limit
Works mainly with companies of 50 or more employees

What a custom build involves, and how to ask about one

3 Markovate

Best for A first AI application started through a short pilot

Markovate ranks third. It is an AI specialist that lists generative AI, agentic AI, conversational AI, computer vision, machine learning and AI automation as services. Its site says each project gets a written scope and estimate after a discovery call, and it offers a focused pilot in 4 to 6 weeks as a first step. That suits a company that wants to test one idea before a larger commitment.

Watch for. The pages we read give no head office, headcount or founding year. It is a specialist in AI work, so look elsewhere for general non-AI systems.

4 Azumo

Best for buyers who want published tier pricing and a nearshore team

Azumo ranks fourth and is the only firm on this list with prices on its site. Project work is billed per Delivery Unit, from $499 to $899 by tier, and the site says price and timeline are shared before work begins. Its work covers AI development, custom software, data engineering and cloud, and it is based in San Francisco with developers mainly across South America.

Watch for. The pricing page says nothing about who owns the code, so ask. Find out how many Delivery Units a project like yours usually takes.

5 10Pearls

Best for larger programs that want nearshore or offshore capacity

10Pearls ranks fifth. It describes itself as an AI-native digital development company, was founded in 2004 and states over 1,400 people, which points to capacity for a larger program. It lists nearshore and offshore development as separate services, with offices in Colombia, Peru, Costa Rica and Pakistan among others, and names healthcare, financial services and telecom among its industries.

Watch for. No pricing page is linked, and the process starts with a discovery call. Ask where the people on your project would be based.

6 Itransition

Best for large companies in regulated or data-heavy industries

Itransition ranks sixth. It is a general software firm of considerable size, stating more than 3,000 professionals and clients served since 1998, and it lists healthcare, finance, manufacturing, retail, insurance and hi-tech as its industries. It ranks in the lower half of this list because the facts we hold describe a broad delivery firm and say nothing specific about AI tools. Ask to see AI work close to yours.

Watch for. The pages we read name no pricing model and no head office, so cost and location are settled in a scoping conversation.

7 ScienceSoft

Best for healthcare, insurance and finance buyers who accept time and materials

ScienceSoft ranks seventh. Founded in 1989 with over 750 IT professionals, it is an established general firm with a stated focus on healthcare, insurance and investment. Its site says more than 90 percent of its development projects are priced on time and materials, with a fixed price offered less often. It ranks here because the facts we hold describe its general software work and not its AI practice.

Watch for. The pages we read say nothing about who owns the code. Raise ownership and the billing model in the first conversation.

8 Intellectsoft

Best for A mid-size firm with a US contact and teams in several regions

The industries it lists include healthcare, fintech, insurance, retail, construction and logistics. It is last on this list for the same reason as the two firms above it, since the facts we hold do not cover its AI work.

Watch for. It has no pricing page, and several engagement models are offered. Ask which one applies to a fixed-scope AI tool.

How this list was ranked

This list ranks firms, not products. We placed AI specialists above general software firms, because the question is who builds custom AI tools, and then weighed what each firm publishes about how it scopes and prices work. Every statement about a firm comes from its own website on the date shown.

Black Badger publishes this guide and is one of the firms on it. We placed ourselves second, for companies of 50 or more employees that want a tool tied to their operations. We have not worked with the other firms and make no claim about the quality of their work.

Questions buyers ask

What should we ask a firm before hiring it to build an AI tool?

Before hiring a firm to build an AI tool, ask who owns the code and the accounts at the end. Ask how the work is priced, and what happens if the scope changes. Find out who will do the work and where they are. Confirm which AI model provider the tool depends on, and on what data terms.

Should we choose an AI specialist or a general software firm?

The choice between an AI specialist and a general software firm depends on where the difficulty lies. If the hard part is the model work, a specialist helps. If the hard part is connecting the tool to your business systems and getting people to use it, a firm that knows operations software may serve you better.

Why is Black Badger ranked on Best Custom AI Tools?

Black Badger is ranked on Best Custom AI Tools because we build custom AI tools and it would be odd to leave ourselves off. We state plainly that we publish the guide, we rank ourselves second and not first, and we describe the other firms only by what their own sites say.

Do firms that build custom AI tools publish prices?

Most firms that build custom AI tools do not publish prices. Of the firms listed, Azumo publishes tier prices per Delivery Unit. The rest quote per project or by engagement model, and Black Badger gives its number in a written scope.
