Decimal AI
An AI support engineer that reads your code, logs, and prod data before it answers a ticket
Last verified September 16, 2026 · Updated daily
What Decimal AI is building
Decimal is an AI support engineer for technical B2B software, and the distinction from a support chatbot is where it looks. When a ticket comes in, it investigates across code, logs, configurations, production data, documentation, and ticket history, then returns an evidence-backed investigation and a draft response with citations, inside the tools the team already uses: Plain, Pylon, Zendesk, Jira, Salesforce, GitHub, Slack. In the company's words, it goes '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.' The design constraints are what make it sellable to engineering-led companies: read-only by default, no foundation-model training on customer data, SSO, RBAC, end-to-end encryption, private storage and VPC deployment options. The founders call the category 'customer engineering': a layer that puts the engineering team's understanding of the product into every customer conversation without pulling engineers off the roadmap. Reported results: Resilinc's mean time to resolution dropped from 6.5 days to 2.5 (62%); Granola handles twice the ticket volume with the same team and resolves 70% of common questions pre-ticket; Omnea averages a 3.8-minute first response at enterprise scale; Composio deflects 95% of technical questions in chat. The company says support interactions resolved have grown 15x since early 2026.
Why this matters
Vinod Khosla's quote in the release is the thesis: 'Support is becoming one of software's biggest hidden costs. Decimal changes those economics entirely.' The specific insight is that in technical B2B products the expensive tickets are the ones support cannot answer without an engineer, and those are the ones a bot with only a help-center index will never solve. Decimal's bet is that an agent with read access to the codebase and prod logs can do the investigation an engineer would have done, which turns a support-cost problem into a retrieval-and-evaluation problem. The founders' backgrounds fit exactly: Kevin built Databricks' vector search from zero to one and ran infrastructure at Eightfold matching across a billion profiles; Sanjeet led AI at Eightfold as it passed $100M in revenue and was an early engineer on Facebook's News Feed ranking. Claire Johnson (ex-Stripe COO) and Rimple Patel (ex-Eightfold CCO) as angels are people who ran support at scale and bought this category.

How to actually get hired at Decimal AI
Why applying the normal way doesn't work
There's an ATS, but at Decimal AI, referrals get priority. Your cold application competes with sourced candidates and internal recommendations.
Who to contact at Decimal AI
What to show them
A one-page account plan for a specific technical B2B company: map their support stack (which of Plain/Pylon/Zendesk, which ticketing), estimate the share of tickets that require engineering escalation, and write the first three emails to their head of support and head of engineering.
A cold email that works at Decimal AI
What Decimal AI screens for
Khosla and Kearny Jackson co-leading a $4M seed with Atlassian Ventures on the cap table is a signal about distribution: Atlassian owns Jira and Jira Service Management, which is where a lot of these tickets live. A six-person team hiring a Staff engineer means the hire will own the core retrieval and evaluation systems, not a slice. The AE and Founding SDR roles mean they are moving from founder-led sales to a repeatable motion right now, and the customer list (Granola, Composio, Resilinc, a Fortune 5) gives a seller real logos to open with. The founders read cold email personally; the window to be the first non-founder engineer is measured in weeks.

Don't make these mistakes
Sanjeet and Kevin have worked together for about a decade and have built ranking, matching, and vector-search systems at Facebook, Uber, Eightfold, and Databricks. 'AI is transforming customer support' is not news to them and neither is RAG. Do not pitch a chatbot, a help-center indexer, or 'deflection'; the entire product is built on the premise that deflection without investigation is what customers hate. Do not send a resume: the founders have said publicly they want deliverables. Lead with a specific support ticket you have seen that required reading logs or code to resolve, and what evidence an agent would have needed to get it right.
Mistakes that kill Decimal AI applications
A recycled CV gets rejected fast at Decimal AI ( people). They notice.
Don't open with what you want. Open with what Decimal AI is dealing with right now — Vinod Khosla's quote in the release is the thesis: 'Support is becoming one of software's biggest hidden costs, and what you'd do about it.
