Decimal AI raises $4M seed for an AI Support Engineer that reads code and logs
Decimal AI said it raised $4 million in seed funding co-led by Khosla Ventures and Kearny Jackson, with Atlassian Ventures and Weekend Fund participating. The San Francisco company sells an AI Support Engineer meant to resolve software customer issues end to end — including digging through code, logs, and production data — and create bug-fix drafts for engineering review.
Same-day SOFTWARE primary that a support-AI startup closed a Khosla- and Kearny Jackson-led $4 million seed to ship an engineer-grade agent that investigates code and logs — not just chatbot FAQs — with named B2B software customers and claimed MTTR cuts.
Decimal AI, a San Francisco company that calls itself the customer engineering platform for technical support teams, announced a $4 million seed via PR Newswire on 15 Sep 2026. Seed is early venture funding — a first institutional check, not a later growth round. The release is titled “DECIMAL AI ANNOUNCES $4 MILLION SEED ROUND TO BRING CUSTOMER ENGINEERING TO SOFTWARE COMPANIES,” dated Sep 15, 2026, 09:04 ET, and datelined SAN FRANCISCO. That company PRIMARY via PR Newswire is the filing event. These are company claims.
The round was co-led by Khosla Ventures and Kearny Jackson, the company said, with participation from Atlassian Ventures and Weekend Fund. Additional backers named: Claire Johnson, former COO of Stripe; Michelle Valentin, founder and executive chairman of Anrok; and Rimple Patel, former CCO at Eightfold. None was printed.
Product, as the company tells it: a Customer Engineering Platform and an AI Support Engineer that resolves software customer issues end to end. Customer Engineering, as Decimal uses the phrase, means bringing engineering-depth — the ability to read what the product actually did — into support tickets, instead of working from a secondhand description. The company says the agent answers questions, takes support 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.
Customers named on the same wire: Granola, Resilinc, Tealium, BuildOps, and Lucidworks, plus a Fortune 5 technology company the company does not name.
Results claimed, still the company’s — attribute, do not independently certify: since the beginning of 2026, support interactions resolved by Decimal grew 15-fold. Resilinc cut mean time to resolution, or MTTR — how long tickets take to close — by 62%, from 6.5 days to 2.5 days. Granola handles twice the ticket volume, resolves 70% of common questions in chat before they become tickets, and automates investigations while improving documentation through auto-generated pull requests.
Founders, as the same release has it: Sanjeet Hajarnis, chief executive, and Kevin Raji Cherian, chief technology officer; they met at Eightfold AI. Hajarnis’s prior roles, the company says: AI lead at Eightfold; early engineer on Facebook’s News Feed ranking systems; pricing systems at Uber. Raji Cherian’s prior roles, the company says: built Databricks’ vector search product and led infrastructure at Eightfold. Extra Eightfold revenue and customer-name color stays in Sources.
Launch timing, company: the product launched in March 2025. The about box also says Decimal is a member of the Nvidia Inception program. File March 2025 and that Inception membership as Decimal’s.
Use of proceeds, company: Decimal says it 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.
Named voices on the release: Vinod Khosla, founder of Khosla Ventures; Hari Arul, partner at Khosla Ventures; Sanjeet Hajarnis; Sriram Krishnan and Sunil Chhaya, co-founders and general partners at Kearny Jackson; and Vicky Firth, head of customer experience at Granola. Their quotes are color only and stay in Sources. This is not investment advice.
Plain English for the rest of the card: seed = early venture funding. MTTR = mean time to resolution, how long tickets take to close. Customer Engineering = Decimal’s name for bringing engineering-depth into support tickets. AI Support Engineer = the company’s agent that investigates code, logs, and production data and drafts bug fixes for review.
