Founded in 2022 by former In-Q-Tel CTO Ravi Pappu, Apeiron Labs develops three-foot-long, 20-pound autonomous underwater vehicles (AUVs) capable of cycling 400 m up and down the water column once or twice per day to sample temperature, salinity and acoustics. Each AUV links to a cloud-based operating system that predicts resurfacing points, uploads sensor readings and refines ocean models on every dive. The cylinders can be launched from boats, airplanes and existing U.S. Navy launchers, allowing rapid, low-cost deployment in lines or arrays spaced 10–20 km apart for high-resolution coverage. Apeiron sells the data and hardware to both civilian markets such as fisheries, offshore wind developers and meteorologists, and to defense customers interested in persistent maritime monitoring. Pappu says the system already reduces the cost of ocean data collection by 100-fold and aims to achieve a 1,000-fold reduction next year. The company positions itself as a “CubeSat for the ocean,” envisioning fleets of dozens or hundreds of units providing continuous sensing. To date, Apeiron Labs has secured $29 million in venture financing, most recently closing a $9.5 million Series A round to scale manufacturing and sales of its AUVs.

Tidal Cyber offers a Threat-Led Defense platform that helps organizations measure and improve the effectiveness of their security stack against real-world threats and adversary behavior. The platform operationalizes MITRE ATT&CK and delivers independent tools and services to align security efforts to the threats that matter without vendor bias. Tidal Cyber plans to build a comprehensive CTI and adversary behavior–driven platform to shift organizations from managing intel to proactive, threat-informed defense. The company raised $10 million in Series A funding to accelerate product innovation and fuel company growth. Tidal Cyber was founded in 2022 and is based in Reston, Va. It was co-founded by three former MITRE experts — Rick Gordon, Richard Struse, and Frank Duff — who bring extensive experience in threat-informed defense and related standards and programs. Tidal Cyber offers a Threat-Informed Defense SaaS platform (Enterprise Edition) that aggregates MITRE ATT&CK®, third-party threat intelligence, and internal research to produce Tidal Confidence Scores and Coverage Maps. The platform recently integrated Breach and Attack Simulation (BAS) test results to compare tests against existing confidence scores. The company also maintains a freely available Community Edition used by over 3,000 security professionals globally. Tidal Cyber plans to use new investment to accelerate go-to-market activities, expand sales and marketing, and enhance both Community and Enterprise Editions. The company reported customer and financial growth exceeding 10x over the past year. Founded in January 2022 by threat-intelligence veterans with experience at MITRE and the U.S. Department of Homeland Security, Tidal Cyber aims to lead adoption of Threat-Informed Defense across critical infrastructure segments. Tidal Cyber offers a threat-informed defense platform that embeds the MITRE ATT&CK knowledge base to help security operations teams focus on the most relevant adversarial tactics and techniques. The platform includes a threat profile builder to identify and prioritize relevant threats, a prioritized to-do list for daily defensive actions, a map to optimize defensive tooling, and a proprietary confidence score to assess cyber posture. Tidal’s tools aim to align threats with the right defensive capabilities and streamline communication about an organization’s security program. The company is led by CEO Rick Gordon, CTO Richard Struse, and CINO Frank Duff. Tidal plans to use newly raised capital to accelerate growth of its platform. The company is based in Reston, VA. Tidal Cyber offers a SaaS-based threat-informed defense platform that maps an organization’s security capabilities to adversary tactics and techniques, including MITRE ATT&CK and additional intelligence sources. The platform includes a registry of vendor product capabilities mapped to adversary behaviors to produce actionable insight on defensive coverage, gaps, and overlaps. Tidal provides a free Community Edition that was made generally available at Black Hat USA in early August, featuring enriched technique data and the Tidal Product Registry. The company plans an enterprise edition with enhanced features, including reporting driven by a Tidal Confidence Score to help evaluate and communicate cyber risk reduction. Led by CEO Rick Gordon, Tidal intends to use the new funding to expand the platform and ramp up customer acquisition. Financially, the company raised $4M in funding to support these product and go-to-market efforts.

LeakSignal builds a microservices cybersecurity platform that classifies and protects sensitive data in transit across microservices, service mesh, serverless and LLM-driven architectures. The company uses Rust and WebAssembly (WASM) within service mesh environments to perform real-time in-transit data classification, map data flows, block threats, and mitigate data leakage. LeakSignal positions its solution as addressing gaps left by API security, DLP, and DSPM tools—namely high false positives and limited visibility into production traffic such as API, log, and database flows. Its platform is used by enterprise customers including multinational banks and airlines, and the company has worked with two of the top ten largest U.S. banks and a major international airline. Headquartered in Atlanta, LeakSignal plans to accelerate product development, expand evangelism, and equip platform and security engineers with in-transit capabilities that integrate natively into modern architectures. Financially, LeakSignal recently closed an oversubscribed $1.6 million seed round to support this growth.
