- TULU
Participated · Series A · Nov 2025
Founded in 2020, New-York-based TULU installs plug-and-play, IoT-enabled cabinets in multifamily buildings that dispense items such as vacuums, VR headsets, e-scooters, projectors, and household essentials. Residents reserve and pay through the TULU app, while the company’s proprietary “TULU Brain” analyzes real-time usage data to personalize offers and supply landlords and brand partners with consumer insights. The platform is active in more than 60 cities across North America and Europe and has served over 500,000 residents to date. Major property owners including Greystar, Brookfield, and Blackstone deploy TULU to boost leasing performance and retention, while brands like Bosch and Philips use it to reach Gen Z and millennial consumers and advance circularity initiatives. Revenue details were not disclosed, but management highlights “exceptional unit economics” and “impressive revenue momentum.” The company plans to use new capital to accelerate global expansion, deploy thousands of additional in-building touchpoints, and further develop its AI capabilities. Across its Seed and Series A rounds, TULU has raised a total of $42 million.
- Prisma Photonics
Participated · Series C · Sep 2023
Founded in 2017 and headquartered in Tel Aviv, Prisma Photonics has developed the Hyper-Scan Fiber-Sensing platform, which combines advanced optical fiber sensing with proprietary AI to detect, classify and localize events along hundreds of kilometers of infrastructure with meter-level accuracy. The system is already deployed across thousands of kilometers and is used by 15 Tier-1 Transmission System Operators in the U.S. and Europe to manage threats ranging from intrusions and wildfires to grid congestion. By leveraging existing fiber, the company eliminates the need for installing additional sensors, creating a scalable, data-rich monitoring network. Each new deployment feeds more data into Prisma’s models, strengthening a self-reinforcing technology moat. Recent traction has encouraged the company to expand beyond its current U.S. and European footprint into Latin America, where utilities are racing to modernize transmission systems and integrate renewables. With the latest financing, Prisma Photonics has raised a cumulative $80 million to accelerate commercial growth and product enhancements. This capital positions the firm to further scale sales, refine its AI models, and fortify its leadership in infrastructure monitoring.
- Frontegg
Participated · Series B · Jul 2022
Frontegg provides a developer-focused user management platform for B2B SaaS, covering sign-up, authentication (including multifactor and magic links), and lifecycle management including subscription enforcement via payment gateway integrations. The company launched a self-service portal for building sign-up and authentication experiences and has recently added enterprise capabilities such as multitenancy. Frontegg aims to let SaaS teams ship mature user management without building it themselves, reducing time to market. The company serves more than 150 B2B SaaS customers, including Datadog, Materialize, Hunters.AI and Tomorrow.io. Frontegg plans to use the new funding to expand product offerings, invest in its infrastructure, and scale R&D and go-to-market teams in Tel Aviv and the San Francisco Bay Area. Total funding to date is $70M following the new $40M Series B. Frontegg offers a modern user management platform that supplies day-one tools such as single sign-on, security policies, audit logs, and a customer-facing admin portal with self-serve capabilities. The platform is designed to let product-led teams implement user management quickly, claiming a single full-stack developer can enable features within days. Current customers include Materialize, Pay.com, Medigate, Talon Cyber Security and Hunters.AI. Founded in 2019 and based in Tel Aviv, the company plans to accelerate platform development to cover more use cases and expand marketplace and channel opportunities. Frontegg will use new funding to grow its engineering team and build out sales and marketing, particularly in the United States. The company cites hiring engineering talent as a major challenge amid strong competition for candidates. Frontegg offers a set of enterprise-ready building blocks that let SaaS teams integrate common features such as authentication, roles and permissions, audit logs, in-app alerts, push notifications and reporting. The product focuses on three main areas: security, connectivity and engagement, and emphasizes enabling customer self-service. Its tooling is intended to save engineering time on table-stakes capabilities so teams can focus on core product differentiation. The founders, Sagi Rodin (CEO) and Aviad Mizrachi (CTO), previously worked together at Check Point and bring security and engineering experience. Frontegg is Tel Aviv–based and about one year old, with 16 employees. The company plans to use the new funding to expand the team and further build out the product.
