Paris YC W24 AI product analytics for LLM apps with session monitoring and evaluation tools; €1.7M Elaia/YC seed pivoting from GenAI monitoring to AI robotics SDKs competing with LangSmith and Langfuse for LLM observability.
About
Phospho is a Paris, France-based AI product analytics platform — backed by Y Combinator (W24) with €1.7 million raised in January 2024 led by Elaia Partners with YC participation — providing AI product teams, developers, and LLM application builders with monitoring, analytics, and testing tools for conversational AI and text-based AI applications. Founded in 2023 by Pierre-Louis Biojout and Paul-Louis Venard, phospho initially built a monitoring and analytics layer for generative AI applications (tracking user interactions, detecting edge cases, extracting insights from LLM conversation logs) before pivoting and expanding into AI robotics (providing Python SDKs, hardware kits, and tutorials that lower the barrier for developers to build intelligent robots). The 2-person founding team is based in San Francisco and Paris.

About
Automatic Data Processing, Inc. (ADP) is a Roseland, New Jersey-based payroll processing and human capital management company — publicly traded on the NASDAQ (NASDAQ: ADP) as an S&P 500 Information Technology component — providing payroll processing, tax administration, benefits administration, HR management, time and attendance, talent management, and retirement plan services to 1.1 million clients ranging from small businesses (1-49 employees) to large enterprises (1,000+ employees) through approximately 58,000 employees globally. In fiscal year 2024 (ending June 2024), ADP reported revenues of $19.2 billion (+7% year-over-year) and adjusted EPS of $9.14 (+12%), continuing the company's consistent mid-to-high single digit revenue growth and double-digit EPS growth from operating leverage and capital return. CEO Maria Black (appointed 2023, ADP's first female CEO, previously leading ADP's employer services division) leads ADP's strategy of deepening client platform engagement: ADP's "employer of record" (EOR) and professional employer organization (PEO — ADP TotalSource) services handle all payroll, HR compliance, and benefits administration for small and mid-size businesses — creating outsourcing relationships where ADP becomes the operational HR department for companies that lack internal HR expertise. ADP's client fund float (ADP holds $55+ billion in client payroll funds between the time employers fund payroll and ADP distributes payments to employees and tax authorities — a multi-day float period generating interest income on $55B at current interest rates) generated $1.6B+ in interest income in FY2024 as rates remained elevated, creating an earnings tailwind that amplifies ADP revenue growth during high-interest rate environments.
