About IDTechEx reports

What are the qualifications of the people conducting IDTechEx research?

Content produced by IDTechEx is researched and written by our technical analysts, each with a PhD or master's degree in their specialist field, and all of whom are employees. All our analysts are well-connected in their fields, intensively covering their sectors, revealing hard-to-find information you can trust.

How does IDTechEx gather data for its reports?

By directly interviewing and profiling companies across the supply chain. IDTechEx analysts interview companies by engaging directly with senior management and technology development executives across the supply chain, leading to revealing insights that may otherwise be inaccessible.
 
Further, as a global team, we travel extensively to industry events and companies to conduct in-depth, face-to-face interviews. We also engage with industry associations and follow public company filings as secondary sources. We conduct patent analysis and track regulatory changes and incentives. We consistently build on our decades-long research of emerging technologies.
 
We assess emerging technologies against existing solutions, evaluate market demand and provide data-driven forecasts based on our models. This provides a clear, unbiased outlook on the future of each technology or industry that we cover.

What is your forecast methodology?

We take into account the following information and data points where relevant to create our forecasts:
  • Historic data, based on our own databases of products, companies' sales data, information from associations, company reports and validation of our prior market figures with companies in the industry.
  • Current and announced manufacturing capacities
  • Company production targets
  • Direct input from companies as we interview them as to their growth expectations, moderated by our analysts
  • Planned or active government incentives and regulations
  • Assessment of the capabilities and price of the technology based on our benchmarking over the forecast period, versus that of competitive solutions
  • Teardown data (e.g. to assess volume of materials used)
  • From a top-down view: the total addressable market
  • Forecasts can be based on an s-curve methodology where appropriate, taking into account the above factors
  • Key assumptions and discussion of what can impact the forecast are covered in the report.

How can I be confident about the quality of work in IDTechEx reports?

Based on our technical analysts and their research methodology, for over 25 years our work has regularly received superb feedback from our global clients. Our research business has grown year-on-year.

This approach delivers exceptional value to our customers—providing high-quality independent content while saving customers time, resources, and money.

Why should we pick IDTechEx research over AI research?

A crucial value of IDTechEx research is that it provides information, assessments and forecasts based on interviews with key people in the industry, assessed by technical experts. AI is trained only on content publicly available on the web, which may not be reliable, in depth, nor contain the latest insights based on the experience of those actively involved in a technology or industry, despite the confident prose.

How can I justify the ROI of this report?

Consider the cost of the IDTechEx report versus the time and resources required to gather the same quality of insights yourself. IDTechEx analysts have built up an extensive contact network over many years; we invest in attending key events and interviewing companies around the world; and our analysts are trained in appraising technologies and markets.
 
Each report provides an independent, expert-led technical and market appraisal, giving you access to actionable information immediately, rather than you having to spend months or years on your own market research.

Can I speak to analysts about the report content?

All report purchases include up to 30 minutes of telephone time with an expert analyst who will help you link key findings in the report to the business issues you're addressing. This needs to be used within three months of purchasing the report.

What is the difference between a report and subscription?

A subscription from IDTechEx can include more reports, access to an online information platform with continuously updated information from our analysts, and access to analysts directly.

Before purchasing, I have some questions about the report, can I speak to someone?
