- Deductive AI
Participated · Seed · Nov 2025
Deductive AI offers a unified platform that connects to an organization’s codebase, logs, metrics, traces, and events, allowing its agentic AI to reason over a constantly updated knowledge graph and surface root causes within seconds. The system mimics the workflow of experienced SREs, generating and testing hypotheses, evaluating evidence, and guiding engineers through remediation rather than stopping at problem detection. Powered by reinforcement learning and code-aware reasoning, the company claims it can cut incident resolution times by up to 90%, giving engineering teams more time to build new product features. Early customers such as DoorDash, Foursquare, Kumo, and Apoha report accelerated triage and clearer insights during high-stress outages. Founded by Databricks and ThoughtSpot veterans Sameer Agarwal (CTO) and Rakesh Kothari (CEO), the company publicly launched in November 2025. Deductive AI is headquartered in Mountain View, California and is backed by CRV, Databricks Ventures, Thomvest Ventures, and PrimeSet. The recent seed funding totals $7.5 million, providing the financial runway to expand product capabilities and customer adoption. No revenue or user numbers were disclosed in the announcement.
- Pixee
Participated · Seed · May 2025
Pixee offers an enterprise-grade platform that automates the last mile of application security, turning alerts into deterministic and agentic-AI-generated code fixes that create pull requests developers can accept. The product integrates with GitHub, GitLab, Bitbucket, and Azure DevOps and provides an on-premises deployment option to keep source code and IP under customer control. Pixee combines agentic AI for context and logic with deterministic techniques to deliver trusted triage and automated remediation. Early customers report recapturing 91% of developer remediation time, cutting security triage time by 74%, and automated fixes achieving a 76% merge rate (the company summary also cites an 87% merge rate). The company plans to use new capital to accelerate product development and expand its go-to-market team to scale enterprise adoption. Founders Surag Patel and Arshan Dabirsiaghi bring decades of security and developer enablement experience, including prior roles at Contrast Security.
- c/side
Participated · Seed · Sep 2024
c/side offers an advanced proxy service and an AI-driven detection engine to identify and neutralize malicious third-party browser scripts in real time. Its toolkit is designed to monitor, optimize, and secure client-side third-party scripts that attackers exploit to redirect visitors, steal data, or manipulate content.

The company plans to accelerate product development, deepen its vulnerability detection engine, and expand its team across customer service, sales, partnerships, and marketing. Financially, c/side announced a $6 million seed round and reports total funding of $7.7 million following an earlier pre-seed round this year. c/side builds tools to monitor, optimize, and secure vulnerable browser-side third-party scripts such as ads, captchas, analytics, and chatbots. Its toolkit offers continuous real-time monitoring and AI-driven scanning of scripts to ensure immediate detection and neutralization of threats, automatically removing harmful scripts. The company positions its product to simplify meeting compliance requirements related to third-party scripts for businesses. c/side plans to use the funds to accelerate product development, partner programs, and go-to-market initiatives. The approach is framed as preserving a secure online experience for businesses and consumers alike. c/side is led by founder and CEO Simon Wijckmans and is based in San Francisco, CA.
- Tezi
Participated · Seed · Jul 2024
Tezi is developing an AI agent to help HR teams find candidates, sift resumes, schedule interviews and send outreach emails as part of an end-to-end recruiting workflow. The startup leverages the latest large language models and has tuned OpenAI and Anthropic models to its hiring requirements. It has trained models on 250 million licensed profiles from data providers to improve matching by skills and criteria set by hiring managers. Tezi launched at the beginning of this year and is rolling out an alpha to 15–20 design customers now, with a wider beta planned later this year. The founders acknowledge humans must stay engaged today and are working to mitigate algorithmic bias by avoiding reliance on historic hiring patterns. The company raised a $9 million seed to fund development toward a generally available product and further product iteration.
- Sika Health
Participated · Seed · Apr 2022
Sika operates a marketplace that lets customers use pre-funded Flexible Spending Accounts (FSA) and Health Savings Accounts (HSA) to buy qualified wellness and health products directly at point-of-sale. The platform handles regulatory qualification and substantiation, employs legal and medical experts, and partners with a team of doctors to provide consultations and approvals when needed. Sika says vendors listed on its marketplace see average customer spend increase by 55% per order and that it partners with major FSA/HSA issuers covering over 20 million customers. The company takes liability for transactions and removes reimbursements/receipt hassles for vendors by enabling direct purchases. Sika has 10 employees and claims to reduce friction that leaves an estimated $25 billion in FSA/HSA funds unspent annually (about $8 billion of FSA funds expire each year). The company plans to eventually expand into helping consumers spend healthcare plan (insurance) dollars, viewing HSA rules as analogous to insurance claims processes.
