Introduction
In 2004, Krish Subramanian’s college friend Rajaraman Santhanam handed him a document that would shape the next two decades of his life, not a startup pitch, but a savings plan, instructions for setting aside 20-30% of his salary every month. (Insight Partners) The two had long talked about starting a company together, and they knew they’d need a financial cushion first. Seven years later, in May 2011, that patience paid off: Subramanian and Santhanam quit their jobs, brought in two more friends, and built Chargebee in a small Chennai apartment. (Insight Partners) Today, Chargebee is a global leader in subscription billing, valued at $3.5 billion. (OrangeOwl)
The Chargebee Story
Before founding Chargebee, Subramanian spent nearly seven years at TCS and roughly two more at Cognizant, after an early stint at a small e-governance startup called MatexNet. (Forbes) Santhanam and Thiyagarajan T., who had been college roommates, both came from Zoho, as did the fourth co-founder, Saravanan KP, who had actually been Santhanam and Thiyagarajan’s mentor at Zoho before being persuaded to leave and join them. (SeedToScale)
Notably, the founders didn’t start with a specific idea; Subramanian has said he “didn’t care which problem we chose as long as we created a business that could scale.” (Insight Partners) After exploring a few options, including an early performance-management product, the team settled on subscription billing, reasoning simply that “everyone needs to get paid.” (Insight Partners) That decision proved well-timed: as the SaaS and subscription economy exploded through the 2010s, businesses of every size needed infrastructure to handle recurring billing, failed payments, tax compliance, upgrades, and cancellations, problems most companies were still solving with brittle, in-house systems. (RemarkMe)
Chargebee grew into that role steadily, eventually serving customers ranging from early-stage startups to large enterprises like Freshworks, Calendly, Okta, and Fujitsu, and reached unicorn status in April 2021 following a $125 million round at a $1.4 billion valuation. (Forbes India) Less than a year later, in February 2022, the company more than doubled that valuation to $3.5 billion. (Business Today)
Business Model
Chargebee earns revenue through subscription-based SaaS pricing, scaling with customer usage and complexity:
| Revenue Stream | How It Works |
|---|---|
| Core billing platform | Subscription and usage-based fees tied to customer billing volume |
| RevRec (revenue recognition) | Add-on module for accounting and compliance automation |
| Hybrid and usage-based pricing tools | Newer capabilities supporting AI companies billing by compute, API calls, or tokens |
| Payment gateway integrations | Revenue tied to processing partnerships with Stripe, PayPal, and others |

Funding History
| Round | Year | Amount | Key Investors |
|---|---|---|---|
| Series F | 2019 | Undisclosed | Tiger Global, Insight Partners |
| Series G | Apr 2021 | $125 million | Existing investors ($1.4B valuation, unicorn round) |
| Series H | Feb 2022 | $250 million | Tiger Global, Sequoia Capital (co-lead), Insight Partners, Sapphire, Steadview Capital ($3.5B valuation) |
(Sourced from Business Today and Tracxn)
Overall, Chargebee has raised approximately $470-475 million to date, reaching a $3.5 billion valuation in 2022. (Tracxn) The company now serves more than 7,000 customers globally, and analysts have flagged it as a strong structural candidate for an eventual IPO, given its high (~80%) gross margins and predictable recurring revenue base, contingent on the company managing its burn rate toward sustained cash-flow positivity. (ValueForStartups)
Revenue and Growth
Chargebee does not publicly disclose detailed global financials, but its Indian subsidiary reported annual revenue of roughly ₹373 crore in FY24, up 100% year-on-year. (ValueForStartups) The company has said its average customer roughly doubles their own revenue every 18 months after adopting the platform, a dynamic that has historically supported strong net revenue retention. (Chargebee Blog)
Notably, market analysts have highlighted that maintaining net revenue retention above the 120% threshold will likely be a key gatekeeper for any future premium-valued public listing. (ValueForStartups)
Chargebee vs Competitors
Chargebee competes with Zuora, Recurly, and Stripe Billing in the subscription management and recurring billing space. (ValueForStartups) As AI companies increasingly need to bill by usage metrics like compute hours or API calls rather than flat subscription fees, Chargebee has positioned its hybrid and usage-based pricing tools as a key differentiator heading into that shift.
