Founder / CEO
Augusto Marietti
CEO
Augusto Marietti is the CEO and co-founder of Kong Inc. He was 31 years old at the time of the June 2020 interview. Marietti grew up in Italy and founded the predecessor company, Mashape, which launched publicly in 2012 as an API marketplace. During the Mashape years, the team operated with 15 to 20 employees and sustained itself on a $6.5 million Series A for close to a decade. In 2016, Mashape sold its product and business assets to RapidAPI in an asset sale, and Marietti used the existing corporate entity to reboot as Kong Inc, completing a public rebrand in August 2017.
Marietti described the pivot as internally driven by the commercial traction of the open-source Kong gateway, which received its first inbound enterprise customer call five months after open-sourcing the technology, in late 2016. That first customer, the Centers for Medicare and Medicaid Services, signed a support contract within 30 days of that initial call. Net worth was not discussed in the interview.

Customers
Kong Inc reported more than 130 large enterprise customers as of June 2020, described by Marietti as Global 5000 accounts. Enterprise contracts are structured as annual subscriptions starting at six figures. Pricing is based on three dimensions: number of users on the platform, volume of API requests passing through the platform, and number of microservices or services connected. Marietti indicated microservices-based pricing was the newest dimension and expected to be the most powerful expansion lever over time.
The Centers for Medicare and Medicaid Services was the company's first enterprise customer, signing in late 2016. Approximately 95% of new bookings in a typical period came from new logos rather than expansions, reflecting the early stage of the customer base. Thirty percent of deals were paid in cash upfront, and some contracts extended to multi-year terms of up to three years.
Kong Inc serves 130 customers.
Kong Inc Business Model
Kong Inc operates an open-core model in which the free Kong API Gateway drives top-of-funnel adoption and the commercial enterprise platform monetizes that installed base. As of June 2020, the company reported 100 million total open-source downloads and 800,000 trackable active monthly instances. The time from open-sourcing the gateway to the first commercial customer call was five months, and the first contract was signed within 30 days of that call.
Gross margin stood at 85% as of mid-2020. Net dollar retention over the trailing twelve months was 133%, with the most recent quarter reaching 195% due to two large customer expansions. Gross revenue churn over the trailing twelve months averaged below 7%, and the most recent quarter recorded 0% gross revenue churn. Approximately 95% of new bookings in a typical quarter came from new logos. The fully weighted customer acquisition cost payback period was approximately 12 months, meaning the company was spending roughly one dollar to acquire each new dollar of ARR. Monthly burn rate was below $1 million. The company had 15 quota-carrying sales representatives as of mid-2020, with a six-month ramp period and a quota attainment target of four to five times base compensation. Sales representatives were primarily closing inbound leads generated through organic search and open-source adoption rather than outbound prospecting.
