To ensure that the rankings are as accurate as possible, we have based our algorithm on objective, quantifiable data that can be comparatively measured across regions, countries, and cities. We refrained from using subjective tools such as surveys and interviews, and instead utilized data that was either accumulated directly from the StartupBlink map or has arrived from integration with a reliable global data partner. We allow as few assumptions as possible regarding cause and effect and focus on one thing: measuring results. We avoid relying on any theoretical models assuming the causes of success for startup ecosystems. 

Every year our algorithm is more accurate, and it should be noted that the momentum change of each ecosystem is not only influenced by its achievements over the last year, but also by these algorithm improvements. We have been sampling startup ecosystem data on the curated and interactive StartupBlink Global Map, which enables us to test and perfect our algorithm based on vast sets of data. We estimate that the core map dataset has a representative sample covering 10-15% of total relevant entities in global startup ecosystems. In addition, hundreds of thousands of entities and data integrations are taken into account via our global data partners. Each location’s final score is based on the exact same algorithm. However, we are aware that our sample size fluctuates depending on location and data sourcing. Our only intervention in the score is discounting locations where we determined that the sample size of the entities is higher than average. In order to solve issues with lower than average sample size, we have partnered with approximately 100 Ecosystem Partners, most of which are Government agencies, many of them in locations where our data is limited. We offer all governments administrative access to curate the dataset of their ecosystems, at no cost, granting them complimentary access. On our rankings with Unicorns and Exits, we take into account the valuation of each startup and add some special filters to exclude government entities and corporate spin-offs.

The Methodology used in the 11 industry rankings, including Software and Data, is identical to the algorithm of the global rankings, while taking into account the startup database of each industry. However, the fintech Industry rankings are built on an official Fintech Ecosystem Portal: Findexable’s Global Fintech Map, which includes deeper algorithm changes that are customized according to the specific characteristics of the fintech industry.
