Greptime
Greptime is an open-source database company building GreptimeDB, a unified observability database that stores metrics, logs, traces, and wide events in a single engine on object storage like Amazon S3. Written in Rust and built on Apache Arrow and DataFusion, it separates compute from storage to cut costs at scale and speaks both SQL and PromQL. Founded in 2022 by ex-Alibaba and Ant Group engineers, Greptime positions GreptimeDB as a drop-in replacement for the Prometheus, Loki, and Elasticsearch stack, serving customers across connected vehicles, IoT, and observability.
Kloudfuse
Kloudfuse is a Cupertino-based observability company that unifies metrics, logs, traces, real user monitoring, continuous profiling, and LLM monitoring into a single observability data lake that runs inside a customer's own cloud (VPC) rather than a vendor SaaS. Founded in 2022 by veterans of Springpath, Nicira, VMware, and Cisco, it pitches an OpenTelemetry-native, AI/ML-powered platform that gives enterprises data ownership and 60-80% cost savings versus incumbents like Datadog. It launched out of stealth in November 2023 with $23M in funding and is used by companies including GE HealthCare, Zscaler, Tata 1mg, and Automation Anywhere.
Last9
Last9 is a unified observability company that helps engineering and DevOps teams monitor high-cardinality metrics, logs, and traces without the ballooning costs of legacy tools. Built around a Prometheus- and OpenTelemetry-compatible telemetry warehouse called Levitate and a pre-ingestion Control Plane that filters, reshapes, and routes data, Last9 has been used to observe some of the largest live-streaming events in the world - including peaks of roughly 59-61 million concurrent viewers. Founded in 2020 and backed by Sequoia/Peak XV's Surge, Better Capital and others, it targets cost-efficient, full-fidelity observability at enterprise scale.
DBOS, Inc.
DBOS, Inc. is a San Francisco- and Cambridge-based developer infrastructure company commercializing durable execution technology born from a joint MIT-Stanford research project led by Postgres creator Michael Stonebraker and Apache Spark creator Matei Zaharia. Its flagship open-source library, DBOS Transact, adds crash-proof workflow orchestration and built-in observability to ordinary Python and TypeScript programs by persisting application state in Postgres, so software resumes exactly where it left off after a failure - without a separate workflow server. The company pairs the library with DBOS Conductor and DBOS Cloud for managing and hosting reliable backends, AI agents, and long-running workflows.
HoneyHive
HoneyHive is a New York-based AI observability and evaluation platform that helps engineering teams ship reliable AI agents. Built OpenTelemetry-native, it unifies distributed tracing, offline experiments, real-time monitoring, and human-in-the-loop annotation into a single continuous-improvement loop so teams can see not just what an agent output, but how it got there and where it went wrong. Founded in 2022 by Columbia roommates Mohak Sharma and Dhruv Singh, HoneyHive is used in production by enterprises including Commonwealth Bank, NVIDIA, MongoDB, and Pinecone, and raised $7.4M in total seed funding led by Insight Partners.
Paid
Paid is a monetization platform for AI agents. Instead of charging by the seat or the API call, it lets agent builders price by the outcome an agent delivers - points of margin saved, tasks completed, revenue generated - then tracks the underlying costs and margins in real time and hands the customer a receipt proving the value. Founded by Outreach creator Manny Medina and a team that previously built billing at Salesforce, Palantir and Pleo, Paid raised $33.3M across a 2025 pre-seed and seed and is building the plumbing for how software gets paid when the software is an autonomous worker.
Mohak Sharma
Mohak Sharma is the co-founder and CEO of HoneyHive, a New York-based AI observability and evaluation platform that helps companies ship reliable AI agents to production. Built OpenTelemetry-native, HoneyHive lets engineering teams trace, test, and monitor multi-step AI pipelines and answer the deceptively hard question of what their agents are doing and why. Sharma started the company in 2022 with his former Columbia roommate Dhruv Singh, and by 2025 had raised $7.4M in total funding, including a $5.5M seed led by Insight Partners, while serving Fortune 100 customers in insurance and banking.
New Relic
New Relic is a San Francisco-based, AI-powered observability platform that gives engineering teams a single place to see everything running in their software - from application code and infrastructure to logs, user experience, and AI models. Founded in 2008 by Lew Cirne, it helped popularize application performance monitoring (APM) and later coined much of the modern 'observability' category. After going public in 2014 and being taken private in a $6.5 billion deal in 2023, New Relic now serves thousands of companies with usage-based, consumption pricing and a strong bet on AI and agentic observability.
Arize AI
Arize AI builds the observability layer for AI - a platform engineers use to trace, evaluate, and debug models, agents, and LLMs running in production. Its open-source Phoenix library and enterprise platform are used by companies like Uber, DoorDash, Instacart, Reddit, Booking.com, and Duolingo to make AI systems work in the real world.
Observe, Inc.
