Methodology
We collected information from 100 API-first businesses across world based on the funding they got. We selected those API-first companies according to the funding they had raised. We also ensured that our approach covered the list of 70 API portals identified by GGV capital here.
We collected firmographic and traffic data with tools like SEMRush to understand traffic sources. Each portal and API was manually tested whenever possible. The data was collected manually through a detailed review of each portal.
We first looked at the top 10 companies that received the most funding to establish the criteria for evaluating API portals. This led to a grid with all the features we needed to look at and consider. Then, we iterated three times on the analysis grid with features found as potential key differentiators in less funded companies. We collected and stored screenshots to compare them in terms of design and share identified best practices. Below is the list of top API companies we have reviewed.
If you think that additional API companies should be reviewed in our next report, please contact us here with the name of the company to be reviewed and what aspects stand out in terms of developer experience.
