To make an estimate, we'll use a combination of top-down and bottom-up approaches.

Top-Down

• As per available data, there are approximately 200 million businesses globally.
• Considering the nature of Freshworks' products (CRM, Customer Support, ITSM, etc.), they are primarily used by medium to large businesses. Let's assume that only 10% of these businesses have a need for such products, which leaves us with 20 million potential businesses.
• Freshworks, though popular, is just one of many players in this space, competing with firms like Salesforce, Microsoft, and others. Let's assume they capture 5% of this potential market, which gives us an estimate of 1 million businesses.

Bottom-Up

• Freshworks is headquartered in India and has a significant presence in the US and Europe.
• Let's assume that they capture approximately 10% of the mid-to-large business market in India, 3% in the US, and 2% in Europe.
• If there are approximately 2 million such businesses in India, 10 million in the US, and 10 million in Europe, this would mean Freshworks has around 200k customers in India, 300k in the US, and 200k in Europe.
• Adding these numbers up gives us a similar figure of 700k businesses.

Comparing the two estimates, a reasonable guesstimate might be around 850k businesses.
