- Rime
Participated · Series A · Jul 2026
Founded in 2022 by Lily Clifford, Brooke Larson, and Ares Geovanos, Rime develops voice AI models tuned for enterprise phone calls. The company operates a recording studio in San Francisco to collect conversational data rather than relying on web-scraped audio and employs a phoneme-based architecture to adapt pronunciations and brand-specific terms. Rime started with separate pipelines for speech-to-text, text-to-speech, and an LLM but is shifting focus toward speech-to-speech models to reduce latency, improve turn-taking, and handle background noise. It serves customers across food service, healthcare, airlines, and fintech and counts Mayo Clinic, Dialpad, Upstart, and Asurion among its enterprise clients. The startup has about 35 employees and recently hired Rafael Valle as Chief Scientist to strengthen its audio understanding and model work. Rime says its training approach helps increase customer call duration, which it credits with winning enterprise contracts.
- Miravoice
Led · Seed · Apr 2026
Miravoice builds an agentic AI platform that conducts automated phone surveys and voice interviews that sound natural, respond in real time and work across languages. Its AI interviewer handles long-form, quantitative surveys—some exceeding 120 questions and lasting over 40 minutes—and supports open-ended responses, numerical inputs, multiple choice, Likert scales and matrix questions. The platform is designed to collect insights at scale without human interviewers. Miravoice is based in San Francisco and is led by CEO Nishant Jain, CTO Danny D. Leybzon and COO & President Shreyas Tirumala. Following its $6.3M seed round, the company plans to expand operations and advance its development efforts using the new capital.
- Theia Insights
Participated · Series A · Mar 2026
Theia Insights develops a proprietary AI-driven platform that processes corporate data such as regulatory filings, earnings transcripts, and financial disclosures to create a continuously updated, multidimensional view of company activity. Rather than assigning single industry labels, the platform represents companies by evolving exposures across multiple sectors and themes. Its product suite includes dynamic industry classification, thematic analysis, and tools to translate investment ideas into data-driven company universes. Theia’s technology is used by global index providers, asset managers, hedge funds, and banks for research, portfolio construction, and trading workflows. The company plans to expand its platform into new asset classes beginning with private markets and to grow its research, engineering, and global commercial teams. Theia was founded by Dr. Ye Tian, Isami Ito, and Dr. James Thorne and is based in Cambridge.
- RAVEN.IO
Participated · Seed · Mar 2026
Raven.io provides runtime protection for applications, delivering CVE-less behavioral protection without instrumentation or performance impact. Its platform is deployed in production with 11 enterprise customers across insurance and financial services. The company was founded by Guy Franco, Roi Abitboul, and Omer Yair and is based in Palo Alto. Raven.io has registered its technology in three U.S. patents. Following the recent financing, the company plans to accelerate product development, expand U.S. go-to-market efforts, and grow its engineering and research teams.
- Qdrant
Participated · Series B · Mar 2026
Qdrant builds a high-performance, composable vector search engine that lets engineers combine dense and sparse vectors, metadata filters, multi-vector representations, and custom scoring functions at query time. Written entirely in Rust, the platform gives teams granular control over indexing, scoring, filtering, ranking, and latency-versus-precision trade-offs, making it suitable for retrieval-augmented generation, semantic search, and agentic reasoning. The engine deploys flexibly across cloud, hybrid, on-premises, and edge environments and is already used in production by enterprises such as Tripadvisor, HubSpot, OpenTable, Bazaarvoice, and Bosch. Its open-source project has surpassed 250 million downloads and accumulated 29,000 GitHub stars, highlighting strong developer adoption. Qdrant has been recognized in The Forrester Wave: Vector Databases (Q3 2024), GigaOm’s Radar for Vector Databases v3 (2025), and Sifted’s 2025 B2B SaaS Rising 100. The company’s recent Series B financing strengthens its ability to scale these offerings and cement composable vector search as core AI infrastructure.
