Andrew Sieja Net Worth 2026: Relativity Founder, IPO Filing

No reputable outlet has published a net worth estimate for Andrew Sieja, so this page does not give one. The $200 million and $18.8 million figures that appeared on an earlier version of this page contradicted each other and had no source; both have been removed. What is documented is where his wealth comes from: Sieja founded Relativity, the Chicago legal-software company, in 2001. Silver Lake's 2021 investment valued it at about $3.6 billion, and in March 2026 it confidentially filed for a U.S. stock market listing.

What is Andrew Sieja's net worth?

There is no published figure from Forbes, Bloomberg or any other outlet that tracks private fortunes. Relativity is privately held, and neither the company nor Sieja has disclosed how much of it he still owns after outside investment. Without that stake, any dollar figure is a guess.

The company-level numbers are public. Reuters, citing PitchBook data, reported that Relativity was valued at about $3.6 billion in March 2021, when private equity firm Silver Lake invested (Reuters via Yahoo Finance). The same report said the company has raised roughly $2.35 billion in total and completed a $920 million debt refinancing by January 2026. A founder who kept even a small slice of a company of that size would hold a large paper fortune, but the size of his slice has not been reported.

Andrew Sieja's yearly income and salary

His salary and bonus have never been disclosed. Earlier versions of this page listed $750,000 a year, $62,500 a month and $2,000 a day. Those numbers had no source and have been removed. As a board member of a private company he is not required to publish pay.

That could change. If Relativity completes its IPO, the registration statement filed with the Securities and Exchange Commission would normally list major shareholders and director compensation. At the time of writing the filing is confidential, and the company has said it has not set a share count or price range (Global Legal Post).

How Relativity was built

Relativity began life under the name kCura. The Round Funded investor database describes Sieja as a programmer by trade who worked as a technologist for multinationals and consulting firms before starting it. Its Relativity review platform became the core of the business, and the company later took the product's name.

Relativity makes software that lawyers and litigation teams use to collect, search and review large volumes of documents and data, a field known as eDiscovery. Reuters describes its origins as tools for handling digital evidence in lawsuits, later expanded into wider legal data analytics. Its main product today is RelativityOne, a cloud platform that uses machine learning to push the most relevant documents to the top of a reviewer's queue.

Sieja ran the company as president and CEO for close to two decades. In March 2016, while still called kCura, it bought Content Analyst Company, an analytics developer; Sieja said at the time that the deal would let it move faster on Relativity's analytics features (Stanford CodeX). He was also the public face of Relativity Fest, the company's annual user conference, where a 2017 company blog put the audience at about 2,000 attorneys and eDiscovery professionals (Relativity).

Career timeline

Professional life after the CEO role

In June 2019 the Chicago Business Journal reported that Mike Gamson, a LinkedIn veteran, had been named Relativity's next CEO, replacing Sieja (Chicago Business Journal). Sieja moved to executive chairman; the Global Legal Post says he held that role for five years, from 2019 to 2024, and remains on the board.

His other ventures, as listed by the Global Legal Post:

• OnDean (2020): an investment firm focused on legal technology, with philanthropy and motorsports arms.
• Alta Futures (2021): gives grants and investments to social entrepreneurs working on access to education and career advancement.
• OrangeCat Racing: a motorcycle racing team. BMW Group's 2026 press materials list Sieja as team owner of OrangeCat Racing, which runs BMW M 1000 RR superbikes for riders Sean Dylan Kelly and Jayson Uribe as part of BMW Motorrad Motorsport's official U.S. effort (BMW Group PressClub).

Investor databases also list him as an angel investor in early-stage legal tech and software startups, but those listings are self-reported and are not confirmed by press coverage, so this page does not name individual deals.

Recent changes (2025-2026)

The biggest recent event for Sieja's wealth is the planned listing. On March 19, 2026, Relativity said it had confidentially submitted a draft registration statement to the SEC (Reuters). The Global Legal Post noted it would be the first legal-tech IPO since Intapp, DISCO and LegalZoom went public in 2021. The same outlet reported that the January 2026 refinancing combined a $200 million revolving credit line with a $720 million senior secured loan.

An IPO would, for the first time, put a public market price on Relativity shares. If Sieja still holds a meaningful stake, that is when a reliable estimate of his net worth could be made.

Early life, education and family

Little about Sieja's private life is on the public record. Earlier versions of this page carried general statements about his childhood, schooling and a wife; none of it was sourced, and it has been removed. His age, height and weight are also not publicly documented, so this page does not give them. What is documented is that he has lived and worked in Chicago, where Relativity is based.

Net worth compared

Sieja's position is unusual among the business owners profiled on this site because the company he founded has a disclosed multibillion-dollar valuation. Compare the software investor Ben Slivka and the venture investor BV Jagadeesh, or the real estate investor Asher Handler. For most of them, as for Sieja, no outlet publishes a verified personal figure.

Why no estimate is given

A net worth estimate for a founder of a private company depends on three numbers: the company's value, the founder's ownership share, and any cash taken out through share sales or dividends. For Relativity, only the first is public, and it is a 2021 private-market valuation rather than a current price. Silver Lake's investment and later rounds diluted early holders by amounts that have not been disclosed. Until an IPO prospectus or a reputable wealth list reports his holding, the honest answer is that Sieja's net worth is not known.
