- Clarasight
Participated · Series A · Apr 2026
Clarasight provides an AI platform that integrates and normalizes fragmented travel, expense, card and HR data into a real-time, AI-ready model for enterprise travel and expense programs. Its Data Management Agents ingest data from travel management companies, expense tools, card programs and HR systems to enable automated workflows, policy exception detection, what-if scenario analysis, and defensible supplier negotiations. The company reported roughly 10x recurring revenue growth over the prior year and now manages data for programs representing over $5 billion in travel and expense spend. Clarasight counts four of the sixteen largest corporate travel programs in the BTN 100 among its customers, including two Big Four accounting firms, and says customers have cut reporting time by 99% and reduced manual data review cycles by over 90%. The recent Series A financing is intended to accelerate product development and expand go-to-market efforts across North America and Europe. Clarasight positions its platform to give lean teams infrastructure and automation to run complex global travel programs without adding headcount.
- Tamber
Participated · Equity · Apr 2026
Tamber builds assistive, non-generative AI tools for music creation that integrate directly with digital audio workstations (DAWs). Its platform uses sonic intelligence to translate text, voice, and gesture into real-time creative controls for discovering sounds and shaping parameters without interrupting workflow. The company maintains a global sound library powered by original recordings to expand access to culturally diverse material. Tamber positions its tools to help musicians and producers move more fluidly from idea to execution. The company is led by founder Zoe Wrenn and is based in Los Angeles, California. Recent funding will support the launch and further development of its creative suite and AI-powered music-production tooling.
- XBuild
Participated · Series A · Jan 2026
XBuild offers an agentic, chat-based estimating platform trained on measurement reports and site photos to produce standardized, editable bids without demos or onboarding. Its initial insurance-focused tool helped run more than 15,000 projects worth $250 million in its first year, saving contractors over 40,000 hours of estimate preparation. In January 2026 the company released Roofing Proposals, which integrates live pricing from suppliers like ABC Supply, supports leading measurement formats, and provides homeowner e-sign and payment links. XBuild’s system addresses contractors’ pain points around pricing accuracy, cash-flow gaps, and client trust. Founded by former Uber and Postmates executives Jahan Khanna and Rob Moran alongside civil engineer Sharuk Khanna, the San Francisco-based firm blends software and construction expertise. With fresh capital, XBuild plans to expand its “vibe coding” estimating technology into additional verticals such as concrete, landscaping, painting, HVAC, plumbing, and more.
- Hipp Health
Participated · Seed · Oct 2025
Founded in 2024 in San Francisco by David Connors and Faaez Ul Haq, Hipp Health provides behavioral health providers with an AI-powered platform designed to reduce paperwork and improve compliance. The software automates data collection, clinical notes, scheduling, and session compliance while embedding analytics directly into clinical and operational workflows. It also expedites billing through automated claims validation and follow-up solutions, addressing complex Medicaid requirements. The company targets the hundreds of thousands of behavioral health practitioners in the United States who struggle with administrative overhead. Hipp Health plans to use newly raised capital to accelerate product development, expand its San Francisco team, and further refine its AI capabilities. Although still early-stage, the company positions itself as an essential infrastructure layer for behavioral health operations. No revenue or user figures have been publicly disclosed.
- Kisui Tech
Participated · Series A · May 2024
Kisui Tech develops Adam, an off-road autonomous AI robot engineered to operate outdoors in rough terrain and perform precision agricultural tasks. The company plans to scale Adam’s manufacturing and enhance its capabilities, and to develop and expand attachable work units that handle tasks from tilling to harvesting. Kisui Tech aims to commercialize these attachments to broaden the robot’s use across the farming workflow. The startup has signaled intentions for global expansion to support food production with its technology. The company was founded in 2021 and is led by CEO Tamir Blum, who previously worked on drone technology at SpaceX and researched lunar rovers at Tohoku University after studying aerospace engineering at UCLA. Financially, Kisui Tech recently completed a Series A financing of ¥150 million.
