Round co-led by Khosla Ventures and Kearny Jackson, Decimal’s AI Support Engineer helps Granola, Resilinc, Tealium, BuildOps, and Lucidworks resolve customer issues in minutes
SAN FRANCISCO, Sept. 15, 2026 — Decimal AI, the customer engineering platform for technical support teams, today announced $4 million in seed funding co-led by Khosla Ventures and Kearny Jackson, with participation from Atlassian Ventures and Weekend Fund. Additional backers include Claire Johnson, former COO of Stripe; Michelle Valentin, founder and executive chairman of Anrok; Rimple Patel, former CCO at Eightfold. The company is also introducing the Customer Engineering Platform, a new layer for software support that brings the technical understanding of an engineering team into every customer conversation.
“Support is becoming one of software’s biggest hidden costs,” said Vinod Khosla, founder of Khosla Ventures. “Decimal changes those economics entirely with an AI platform that understands the code and customer context as well as the best support engineers.”
Since launching in March 2025, Decimal has been adopted by leading software companies including Granola, Resilinc, Tealium, BuildOps, and Lucidworks, along with a Fortune 5 technology company. Its AI Support Engineer resolves customer issues end to end, from answering customer questions and taking actions like resolving billing and account issues to investigating code, logs, configurations, production data, documentation, and customer history and creating bug fixes for engineering review.
“AI has enabled the best companies to exponentially increase shipping velocity, but with that comes an exponential increase in support needs,” said Hari Arul, partner at Khosla Ventures. “Decimal is the solution for leading technical enterprises to leverage AI to solve customer issues.”
Since the beginning of 2026, the volume of support interactions resolved by Decimal has grown 15-fold. Resilinc reduced mean time to resolution (MTTR) by 62%, from 6.5 days to 2.5 days. Granola now handles twice the ticket volume, resolves 70% of common questions in chat before they become tickets, and automates investigations while continuously improving documentation through auto-generated pull requests.
“Decimal is especially great at surfacing the issues where we realize there’s something else going on and we need to dig deeper and Decimal has already gotten to the bottom of it,” said Vicky Firth, head of customer experience at Granola. “In general, it’s sped us up a lot and saved us from digging through all those systems.”
Decimal was founded by Sanjeet Hajarnis, CEO, and Kevin Raji Cherian, CTO, who met at Eightfold AI. Hajarnis previously led AI at Eightfold as the company scaled past $100 million in revenue, serving global enterprises including Citibank, Morgan Stanley, Nvidia and Netflix. Earlier, he was an early engineer on Facebook’s News Feed ranking systems and built pricing systems that powered billions of rides at Uber. Raji Cherian built Databricks’ vector search product from the ground up and led infrastructure at Eightfold that powered matching across more than 1 billion candidate profiles and jobs.
“Customer support should not have to operate from a secondhand description of the product,” said Hajarnis, co-founder and CEO of Decimal AI. “The answer to customer questions is usually sitting in what the product actually did. We built Decimal to surface that evidence the moment a ticket arrives, not after a customer has waited through many escalation cycles.”
The company has used the financing to expand the range of technical issues its system can investigate and deepen integrations across the support and engineering tools its customers already use.
“Every software company with a technical problem is going to need this. We think Customer Engineering becomes its own category, the way GTM Engineering did,” said Sriram Krishnan, co-founder and general partner at Kearny Jackson.
“Sanjeet and Kevin didn’t build this from the outside. They have the scar tissue and the expertise to close the gap between support and engineering, and that’s why some of the most technically sophisticated companies in the market trust them,” said Sunil Chhaya, co-founder and general partner at Kearny Jackson.
