Three of the top consulting companies for innovative AI services are Keyrus, Tata Consultancy Services, and Cambridge Consultants. All three of these companies have created innovative AI technologies that have seen them emerge as the market leaders in this field.

KEYRUS
Keyrus has its headquarters in France. It has over 3,200 employees in 18 different countries.
 Disney, AT&T, and AZA are among the companies that rely on Keyrus' AI Consultancy services.
Keyrus had revenues of EURO145.6 million for the first half of 2019. This showed a growth of 7.2% from the same period in 2018.

The company's core business is providing customer solutions for data analytics, as well as insight into AI and machine learning. This can be divided into 2 main areas.
The first area is the assessment, implementation, and upgrading of innovative technological solutions. This includes data intelligence and data experience.

The second area of business is consultation for the major departments and functions of an enterprise. This includes strategy and transformation, management and organization, digital strategies, and performance management.

Keyrus is teaming up with several startup companies to provide innovative AI solutions globally.
This includes LumenAI, who they are working with to bridge the gap between academic research and industry. Together they are using innovative AI technology in the areas of predictive maintenance, predictive marketing, and security in the public sector.

They have partnerships with Dataiku in 3 countries. Together they are applying machine learning and different data science techniques to create innovative predictive data flows.

TATA CONSULTANCY SERVICES
Tata Consultancy Services (TCS) has its headquarters in Mumbai, India.
TCS has offices in 50 countries globally and in the year to March 2019 had consolidated annual revenue of over $20 billion. It is the fastest-growing brand of the decade in IT services.

TCS offers a range of services including Automation and AI, Cognitive Business Operations, Analytics, Internet of Things, Cloud Applications and Infrastructure, Cybersecurity, Blockchain, TCS interactive, and Conversational Experiences.

In 2018 TCS was recognized as one of the leading innovators in AI consultancy, when it was positioned in the Winners Circle at the Enterprise Artifical Intelligence Services Awards Hfs.
In 2019 TCS's venture software company Digitate, was named the Best Overall AI Company at the AI Breakthrough Awards.

TCS has become a leader in this field by solving real-life problems through innovative AI consultancy.

Some examples of how they are innovating using AI include Ignio for performance and decision-making that predicts and prevents problems for businesses, integrating drones to build solutions for industry problems, and TCS Crystal Ball which uses AI technology to act as an observer and enforcer of an individuals' privacy rights.

It has also created, what is being considered the next generation of cognitive (AI) business solutions, with Decision Fabric. This will enable Pharmacovigilance Auto Case Intaking and Triage, Communication Surveillance to minimize misconduct, and Cognitive AML, which automates activities of AML investigators, identifies patterns and detects threats in real-time.

CAMBRIDGE CONSULTANTS

They describe their ability to continuously innovate as being the reason they are a market leader in AI consultancy services. They pride themselves on delivering breakthrough products and services that are highly profitable for their clients.

Previous clients have described their AI innovations as having "out of the ordinary engineering ability" and some solutions even "defy the laws of physics".
 Sharpwave is an example of how they are innovating using AI. This uses AI technology to provide an undistorted and clear view of the real world, based on an obscured or damaged moving image.
It is believed it will have applications ranging from autonomous driving to improving the diagnostic capabilities of healthcare professionals.

Cambridge Consultants has also built and developed its own lab, Digital Greenhouse, which is committed to discovering, developing, and testing new and different approaches to machine learning. This has enabled Cambridge Consultants to develop new and innovative AI technologies and stay ahead of industry trends.

Algorithmic models developed by Digital Greenhouse are continually assessed by the company to provide solutions in a range of fields including medical diagnostics, security and intrusion detection, and industrial automation.

Ask an AI consultancy for evidence at the task level

The historical revenues, staffing figures and descriptions of 'top' firms are not a present ranking. A consultancy's technology demonstration or client list does not establish that it can deliver a particular organization's project under its constraints. Define the task, data access and success measure first.

For a hypothetical proposal, request a limited evaluation on authorized data, failure-case analysis and a handover plan. Identify ongoing model, integration and review costs. Compare the same deliverable across suppliers and separate company claims from independently checked results. A credible offer can explain where the system should defer or stop as well as where it performs well.
