- Invisible
Participated · Equity · Sep 2025
Invisible Technologies delivers a five-module AI platform—Neuron for data integration, Atomic for visual process mapping, Expert Marketplace for RLHF and human validation, Synapse for annotation and evaluation, and Axon for agentic automation—that lets enterprises clean data, codify workflows, and deploy AI agents at scale. Its technology is used by customers such as Microsoft, Swiss Gear, SAIC, and the NBA’s Charlotte Hornets, and the company claims to have trained foundation models for more than 80% of the world’s leading AI providers. Revenue more than doubled year-over-year to reach $134 million in 2024 after growing 24× between 2020 and 2023, earning the #2 spot on the 2024 Inc. 5000 list of fastest-growing AI firms. The company employs about 350 people and has recently doubled its engineering team while adding offices in New York, San Francisco, Washington D.C., and London. New executive hires include former VMware CTO Kit Colbert as Platform CTO and former WeWork CRO Benjamin Samuels as GM of EMEA, underscoring a push toward large-enterprise adoption. Invisible plans to use its new capital to deepen R&D across its modular platform components and expand enterprise go-to-market capabilities. Long-term, management positions the firm as the foundational AI infrastructure layer that helps legacy enterprises operationalize AI and quantify ROI.
- InfluxData
Led · Series E · Feb 2023
InfluxData originated from Errplane and builds InfluxDB, a time-series database and associated cloud service for real-time metrics, logs, events and tracing. The company recently launched InfluxDB IOx, a rebuilt columnar engine that adds SQL support, removes cardinality limits and is marketed as enabling much faster real-time queries. InfluxData offers dedicated cloud tiers and is developing a new on-premises, enterprise-focused product built atop IOx. The platform is used for observability, IoT and other high-volume, high-velocity data use cases and lists customers such as Hulu, Siemens, Tesla, Cisco and IBM. Operating metrics disclosed by the company include roughly 750,000 users on its cloud service, about 6,000 new users per month and more than 1,900 commercial clients; the company has about 165 employees and expects ~10% headcount growth by end of 2023. CEO Evan Kaplan says the company will use the new capital to expand IOx, cloud tiers and its enterprise offering. InfluxData develops InfluxDB, a purpose-built open-source time series database and platform for analyzing metrics and events for DevOps and IoT applications. The platform ingests data from humans, sensors, and machines to power monitoring, analytics, and IoT applications and is developer-focused with strong open-source demand. The company more than doubled revenue, new customer logos, and employees in 2018 and reports more than 450 customers, including Cisco, eBay, IBM and Siemens. InfluxData plans increased investment in product innovation with a heightened focus on the cloud, plus expanded sales, marketing, and customer support. It will begin marketing solutions for specific uses, including industrial IoT and network monitoring, and target industries such as e-commerce, gaming, and financial services. The company is led by CEO Evan Kaplan and is based in San Francisco. InfluxData builds an open source time series database platform that enables collection, storage and analysis of high-volume, time-stamped data. It offers a commercial, closed-source edition for enterprise-scale deployments that provides added security and availability; the commercial product has been available for 18 months. The company reports 120,000 sites running the open-source project and 400 enterprise customers, including IBM, SAP, Cisco, PayPal, Tesla and Siemens. CTO Paul Dix began building the underlying open-source toolkit in 2014 and Evan Kaplan is CEO. Influx currently employs 80 people and plans to double headcount in the coming year. Management is focused on expanding the time series database business to serve larger enterprise needs. InfluxData develops InfluxDB, an open-source time-series database and the accompanying TICK stack for collection, storage, visualization and processing of time-series data. The platform is designed to be easy to consume and to serve as a foundation that other SaaS providers can run on top of. Its technology is deployed across nearly 40,000 unique sites and is used by customers including Nordstrom, eBay, Solar City and Mozilla for real-time metrics and monitoring. InfluxEnterprise, the company’s commercial clustering product, reduces deployment and scaling time and forms a key part of its monetization path. The company says the open-source model has helped build a developer community but has not directly driven revenue growth to date. With the new capital, InfluxData plans to expand marketing and customer acquisition to position itself as a go-to solution for IoT and other high-volume time-series use cases. InfluxData began as Errplane and pivoted to build InfluxDB, an open-source time-series database designed to handle data that changes over time. Founders Paul Dix and Todd Persen shifted from a SaaS anomaly-detection service after customers signaled demand for the underlying infrastructure. The project gained early traction after mentions on O’Reilly Radar and Hacker News, and the community has contributed additional libraries beyond the core team’s work. The company went through Y Combinator and subsequently discontinued its original service to focus strictly on InfluxDB. InfluxData announced $8.1M in funding to continue building the product and to create a commercial entity around the open-source component. For now the team is optimizing for developer happiness and growing the community while planning commercial services later.
- Enpal
Participated · Series D · Jan 2023
Founded in 2017, Berlin-based Enpal offers a fully integrated package for climate-neutral homes that bundles photovoltaic systems, battery storage, EV chargers, heat pumps, green electricity tariffs and a smart energy manager. Central to its model is a rental financing programme that removes the high upfront cost of hardware and connects customers to Enpal.One+, an AI platform that aggregates household batteries into a virtual power plant and trades excess electricity on the market. The company has installed more than 300,000 decentralised energy systems for over 100,000 customers, making it Europe’s largest residential solar installer and Germany’s leading independent metering point operator. Enpal has also become the country’s largest provider of installed heat pumps. Backed by investors such as TPG Rise Climate, SoftBank Vision Fund II and HV Capital, the firm continues to layer project-level financing on top of its equity base to scale rapidly. The new €700 million ABS warehouse and €600 million in senior bank loans deepen its capital stack and are intended to accelerate monthly household conversions to renewable energy. Enpal plans to leverage this capital efficient structure to expand further across Europe while reinforcing energy independence.
