Addepar

Addepar, Inc. is an American financial technology company that provides a cloud-based wealth and investment management software platform specializing in data aggregation, analytics and portfolio performance reporting. Its clients are primarily registered investment advisors (RIAs), single-family offices, banks, institutional asset owners and alternative fund managers, serving high-net-worth and ultra-high-net-worth individuals and companies. The platform consolidates financial accounts and investments across custodians and institutions, enriches them with market and third-party data, and represents holdings and transactions in a unified data model that supports complex ownership structures, multiple asset classes and multi-currency portfolios.

Core capabilities include continuous data aggregation with direct data feeds, automated data verification checks routed to a data operations team when inconsistencies are detected, on-demand portfolio calculations and visualization, drag-and-drop and template-based client reporting, and open APIs with pre-built and custom integrations to third-party systems. The company positions handling of alternative investments — capturing and standardizing alternatives data alongside public holdings for exposure, performance and liquidity analysis — as a distinct area of the platform, and has been embedding AI-based workflows, including automated extraction and standardization of complex documents. Products described publicly include the Addepar Platform, an Open API, a mobile application launched in 2019, and Navigator.

Addepar describes itself as a global data and AI company serving the financial services ecosystem, with its platform used across 60+ countries and markets and an ecosystem of software, data and services partners.

Founding story

Joe Lonsdale, who in 2003 co-founded Palantir Technologies with Peter Thiel and others, launched Addepar in September 2009 with Jason Mirra, another Palantir employee. The company was created in response to the 2008 global financial crisis with the stated goal of making the financial system more transparent so that owners could understand what they hold, where it is invested and how it is performing. The name derives from a line in Ovid's Metamorphoses meaning "Add a little to a little and you'll have a great amount." Mark Zuckerberg was among its earliest clients.

Business model

Addepar sells a software platform to financial institutions and advisory firms rather than to end investors, packaging data aggregation, analytics, reporting, integrations and, more recently, AI-enabled workflows. It offers tiered or tailored implementation options intended to fit firms ranging from those with limited resources to large multi-advisor organizations, and it integrates with more than 100 software, data and services partners as part of the delivered solution.

Sources describe a client-firm model in which more than 1,200 client firms use the platform to manage and advise on client assets; the company reported strong revenue growth, high client retention and being on track for profitability in 2025, and reinvests over $100 million annually in research and development.

Traction

As of May 2025, Addepar's platform aggregated data for more than $7 trillion in client assets across more than 1,200 client firms in more than 50 countries, adding an average of more than $25 billion in new assets each week, with hundreds of thousands of users. Company materials later cite more than $9 trillion in assets across 1,500+ clients in 60+ countries and 100,000+ users. Assets under administration were reported to have grown by about $1 trillion in the year to June 2024, with nearly half of that from RIAs. Addepar reported $500 billion in assets on the platform in October 2016.

Latest developments

In May 2025 Addepar announced the closing of a $230 million Series G at a $3.25 billion valuation, co-led by Vitruvian Partners and WestCap with participation from 8VC, Valor Equity Partners and new investor EDBI; the round's primary purpose was a tender offer providing liquidity to employees and existing shareholders, and it was completed in the first quarter of 2025 ahead of the May announcement. The company said it invests over $100 million annually in R&D and was on track for profitability in 2025. In February 2025 it announced a new R&D center in Pune, India. In 2025 it acquired AI workflow automation startup Arcus for an undisclosed amount, and in November 2025 appointed Peter O'Brien as Chief Revenue Officer and Janeen France as Chief Client Officer. Current leadership also includes CFO/COO Eric Daniels and CTO Bob Pisani.
