Business/Industry Directories: Education

The 12 popular business listings, industry, or niche directories for companies in the educational innovation or tech industry/vertical include eLearning Industry, EdSurge, Centre for Learning & Performance Technologies,, Edshelf, Training Industry, The Elearning List, CB Insights, Tracxn, Christensen Institute, HolonIQ, and Encoura.


We started the search by looking for a comprehensive and precompiled list of popular business listings, industry, or niche directories for companies in the educational innovation or tech industry. We used different reliable media sites, blogs, news sites, and update sites in the educational category. That includes Dive, EduWeek, The Learning Network, Edudemic, Educational Technology and Mobile Learning, and others. However, the search did not yield fruitful results. The only information we found was a list of product listings according to reviews or performance but nothing on directories or listings.

We then manually searched for business listings or product listings related to education innovation or education technology. We then compiled them in the spreadsheet. We used Hyperstat to find their total monthly visits, and we used the total monthly visits to determine the popularity of the directory. We then picked the seven sites with the most monthly visits. Numbers 8-12 were meant for the market maps. We also looked into each of the websites to determine the size of the directory, age or year the directory began, and the quality of the listing (possibly from reviews of the listing or industry expert analysis of the directory for the industry).

We then looked for educational market maps and compiled them in the spreadsheet. We used Hyperstat to determine the market maps’ monthly visits, and we used the monthly visits as the determinant of popularity. We then ranked each map from highest to lowest, and chose the top market maps and compiled them in the research brief. Additionally, we added the link of the directories and the market maps to the proper headers provided in the research brief.

Business/Industry Directories: Space/Space Technology

We've identified 10 more popular business listings, industry, or niche directories for companies in the space and space technology industry. These niche business listings are Disruptor's Top 100 Most Disruptive Space Companies, Spacefrontier's Newspace Directory, SpaceCareer's Space Industry Directory, Satnews' International Satellite Directory, UK Space Directory, NewSpace Hub Directory, CBInsight's The Space Tech Market Map, Microcom's Satellite Industry Links, Spacebiz Guide Business Directory, and NLSpace Directory.


To determine the most popular business listings/directory or database in the space and space technology sector, our first approach was to search for a comprehensive list of directories specific to this market, however, this list is not made available in the public domain. We then listed and curated all the directories, listings, databases, guide, links, and maps we found available including online directories, paid directories and/or printable directories. We've listed their corresponding URLs in this spreadsheet.

Next, since there were no reviews available for these listings (databases), to determine which of these directories are considered popular, we used a website analytic tool, Hypestat, to determine monthly unique visitors of these websites. We entered the results in the spreadsheet, including other findings.

From the numbers, we then ranked them according to their monthly visitors. For this research, we've only included those directories that can be accessed even without paying. We also included those listings that were not necessarily termed as directories and included those listings/databases whose names of the said niche market companies have comprehensive lists. To determine the age or year the directory began, we utilized Wayback Machine, an internet archive that lists down historical activities of any given website. We have summarized our findings below.


This listing provides the 100 most disruptive space companies globally that are initiating unique innovations and technology in the space industry. Their ideas and innovations include realization to "science fiction, efficient spacecraft drives, personal satellites, and reusable spacecraft." This listing was first published in 2017 in DisruptorDaily's website.

This directory consists of 48 companies that are described by Space Frontier as "informal directory of companies and organizations associated with NewSpace" but it also provides a broad overview of the space technology market. From the internet archive, this directory's first activity was captured back in 2012.

This niche directory "contains a comprehensive collection of links to space-related companies who have a presence on the Web." The information provided in the directory was mostly extracted from each company's webpage. These companies are categorized as follows: civil agencies/international organizations, satellite manufacturers and subcontractors, satellite operators, ground systems, software and equipment, launch systems, business services, and consulting/engineering services. This directory was first created back in 2005.

This directory is a paid directory, however, it still provides lists of these companies (while comprehensive list needs to be purchased), hence, we included them here. This directory is updated annually with over 25,000 entries. Contents of this directory includes International Agencies, Manufacturers of Satellites and Space Equipment, Manufacturers of Satellite Ground Equipment, Network Systems, PC-Satellite Connectivity, Users of Satellite Systems, Providers of Satellite Services, Geosynchronous Satellites, EIRP Maps (online access), and Uplink Facilities. This directory was first published in 2013.

There are 711 unique listings in this niche space-related directory. The companies are categorized as per the following: Ancillary Support, ServicesFunding & Investment, Incubation Centres, Key Sector Organisations, Networks, Research Centres, Space Applications Companies, Space Manufacturing Companies, Space Operations Companies, Space Test Facilities, and Spaceports. This directory was first released in 2016.
This database highlights "worldwide new and lesser-known NewSpace companies, products, projects, services, and tools, every day." It attracts astropreneurs, space professionals, analysts, and investors. Newspace Hub does not have a record in the Wayback Machine internet archive, but the company was founded in 2017 and we've assumed that the database was also first released on the same year.

CB Insights is known to curate startup companies in any industry. For this particular map listing, CB Insights listed "57 space tech startups and organized them into three categories and eight subcategories, based on each company’s primary product, line of business, and/or current focus." The list was first published in 2017.

This directory was published by Microcom in 2014. The website claims that it has

This includes satellite operators & connectivity solutions, network systems & teleport operators, satellite ground equipment manufacturers, space engineering services & consultancy, space exploration & commercialization, among others. Spacebiz Guide does not have a record in the Wayback Machine internet archive. but the company was founded in 2015 and we've assumed that the database was also first released in the same year.

We started the search by looking for precompiled information about the most popular business listings and directories related to the water tech industry. However, no such list could be found in the public domain. We then decided to list and curate all the directories, listings, databases, guide, links, and maps that we have found and made a spreadsheet with each of their URLs. It is important to note that these directories and business listings are focused on industrial-sized water tech and solutions for large entities. We confirmed this by looking through each of the organizations’ pages and confirming that their featured listings are for industrial sized entities.

We then determined the popularity of each of the directories with the use of Hyperstat. Hyperstat helped establish the number of unique monthly visitors that each site has, and we inputted this information in the spreadsheet. When we discovered that two of the websites from the list have the same number of visitors, we decided to place their worldwide rank to help determine which of the two companies is more popular than the other. We then entered the results in the spreadsheet. Lastly, we excluded companies that did not have enough information.

We then ranked each organization and website with the data we have found. The site with a higher number of unique visitors is our measure of popularity. We also scoured the about page of each website to provide a short general overview of the organization. We also looked for the size of the directory, the age of the directory, and when it began. We also used the Wayback Machine, an internet archive that lists historical activities of a given website, as a way to determine the age of the directory and when it began.

The business listings, industry, or niche directories for companies in the energy & clean tech, dealing with innovation or technology, industry/vertical include Cleantech Group, Energy Planet, NCtech, Clean Energy World, and Cleantech San Diego.

To provide popular business listings, industry, or niche directories for companies in the energy & clean tech, dealing with innovation or technology, industry/vertical, we began our research by searching for any readily available information in the public domain. However, there was no resource providing a list of such directories.

Therefore, we searched for individual directories. Still, there were very few directories specializing in this niche sector, probably because it is still new. However, we managed to provide nine directories that fit the criteria.

Since there was no clear metric to determine top directories, we decided to use Hyperstat to establish the number of unique monthly visitors. We ranked each directory/organization based on the number of unique monthly visitors. To determine the age of each website, we used Wayback Machine. Notably, the information on the number of unique monthly visitors is unavailable.

Business/Industry Directories: Food/Food Tech

After careful research, we have identified a total of eight popular business listings, or niche directories for companies in the food/food tech industry, that are dealing with innovation or technology, industry/vertical. These include IFT Services, IFSQN, Go Food, Food Hub, Food Safety News, the National Coffee Association, USDA AMS, and Food Technology News. Below we have presented an overview of our research strategy, any assumptions we have made, and the findings from our research.


To identify popular business directories that meet the specified criteria, we initially analyzed various financial and business-related sites to obtain a thorough understanding of the types of companies that could be included in such a directory. We then expanded our search to explore for listings that concentrate on the food technology sector. However, we were unable to discover a definite ranking of directories concerning the food industry. Therefore, we administered additional criteria to compile a list of we assumed are among the most prominent examples. First, we ensured that every directory we included was either current or routinely updated by the host site.

We also compared the reported website traffic for numerous listings, though there was not sufficient data available for some to determine this information. Nonetheless, it seemed that the directories that are more widely utilized average at least 100,000 visitors each month. Additionally, we omitted directories that we believed had a low amount of businesses listed and concentrated on those that appeared to sustain a more robust database. Although the methods we employed to determine the prominent food and food tech directories was slightly more subjective than ranked data sets, we assume that our list offers an adequate overview of some listings that are currently available.




Organized in 1939, IFT has recently begun to disclose an updated (annually) directory of companies operating in the food technology sector. Its website receives about 164,000 monthly visits, as listed by Similar Web. IFT has around 341 listed businesses in its 2019 directory.

Mostly targeted towards drink and food entrepreneurs seeking to expand their business, Food Hub functions under the concept of "word of mouth" networking. The directory divides its listings among the categories of Selling, Business, and Product, with several sub-categories placed beneath each one.


As a result of the struggling printed and broadcast media industry, Food Safety News (FSN) was introduced. FSN concentrates on distributing news concerning food safety. However, it also offers a massive directory for those seeking to acquire information about businesses that FSN typically covers. FSN enjoys an estimated 453,000 monthly visitors. Moreover, its directory consists of 34 categories that facilitate individuals to narrow down the specific type of company they are investigating.


Organized in the year 1911, the National Coffee Association (NCA) organizes an international network of every business aspect of the coffee industry including roasting, packaging, and distribution. The NCA has up to 99,000 monthly visitors. Also, the NCA has 160 individual listings.

Business/Industry Directories: Healthcare Tech

After conducting extensive research, we were unable to find any business listings, industry, or niche directories for companies in the healthcare tech, dealing with innovation or technology, industry/vertical, as the information is not publicly available. However, we found healthcare business directories ranked among the top 100 online directories to include HealthGrades, ZocDoc, Vitals, and RateMDs. Below, we have provided the research strategies used to find the requested information, and which also explain why the information was unavailable.


We approached this request by first searching for a possible pre-compiled list of top healthcare tech business directories on the public domain, and found a source which showed a ranking of the top 100 business directories in the US. The ranking was based on the US Alexa ranking system, from which we found a couple of business directories relating to healthcare businesses. We then looked for the healthcare tech directories from other sources which we have provided in our findings.
Next, we checked to see if the identified business directories were in line with the criteria for the request, but unfortunately, we discovered that they only provided info on where to find the best healthcare professionals, health-related terms, services, and best healthcare organizations and facilities. None of the business directories provided listings of healthcare tech, dealing with innovation or technology, industry/vertical.
We then proceeded to check for more information on some websites like PHP portal, New Choice Health, AngelList, 4A's directory, Clutch, AdForum, etc., to find data for other top listed healthcare directories to meet the requested criteria. However, this strategy yielded similar results as the previous one.
Lastly, for each healthcare directory listed, we tried to find an overview of their size, quality (depending on reviews) and the year they were established. However, we only saw a summary for each of them and expanding the search by going through their websites only provided information about what they do. The information regarding healthcare tech directories is comprehensive, although there is a vast pool of healthcare tech directories. However, we did not find a single list that met the criteria for this request.


The following healthcare business directories are ranked among the top 100 business directories online:

HealthGrades is a site that provides information about physicians, dentists, hospitals, and health care providers.

ZOCDOC (Rank 34)
ZocDoc links healthcare businesses to a massive network of local consumers which generates traffic of about 120 million different doctor searches on Google. ZocDoc provides 24/7 online booking, reminders, and review collection of healthcare pros to its users.
