San Francisco, Sept. 15, 2026 — Decimal AI announced $4 million in seed funding and the launch of its Customer Engineering Platform, a new layer for software support that brings the technical understanding of an engineering team into every customer conversation. The round was co-led by Khosla Ventures and Kearny Jackson.
The seed round also included participation from Atlassian Ventures and Weekend Fund. Additional backers named by the company are Claire Johnson, former COO of Stripe; Michelle Valentin, founder and executive chairman of Anrok; and Rimple Patel, former CCO at Eightfold.
Co-founders Sanjeet Hajarnis (CEO) and Kevin Raji Cherian (CTO) said the company has built an “AI Support Engineer” that resolves customer issues end to end. According to Decimal, the AI Support Engineer answers customer questions, takes actions such as resolving billing and account issues, investigates code, logs, configurations, production data, documentation and customer history, and creates bug fixes for engineering review.
“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.”
“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.”
Decimal AI’s Customer Engineering Platform
Since launching in March 2025, Decimal has been adopted by software companies including Granola, Resilinc, Tealium, BuildOps and Lucidworks, as well as a Fortune 5 technology company. The company says its platform helps technical support teams resolve issues more quickly by embedding engineering-level context into customer interactions.
Decimal reported that, since the beginning of 2026, the volume of support interactions it resolves 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, automates investigations and continuously improves 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.”
