Arnie Bellini Net Worth 2026: ConnectWise Founder and Philanthropist

No reputable outlet has published an estimate of Arnie Bellini's net worth. The $76 million figure that appeared on this page before had no source, and it looks far too low next to what is on record. Bellini co-founded the Tampa software company ConnectWise with his brother in 1982 and sold it to private equity firm Thoma Bravo in 2019 for a reported $1.5 billion. Since then he and his wife, Lauren, have pledged or given well over $100 million to universities, schools and local causes, and he now invests through his family office, Bellini Capital.

What is Arnie Bellini's net worth?

Forbes and Bloomberg do not list him, and Celebrity Net Worth has no entry. The key missing number is his share of ConnectWise at the time of sale. The company was founded by Arnie and his brother David, David left in 2018, and the sale made more than 70 current and former employees millionaires, according to ChannelE2E and Axios. That means the $1.5 billion was spread across family members, employees and any outside investors, and the split was never disclosed.

Even so, the scale of his giving points to a fortune well beyond the old $76 million figure. Documented pledges and gifts from the Bellinis include:

• $70 million pledged in 2019 to Tampa Bay causes over 20 years, with a goal of creating tens of thousands of local tech jobs (ChannelE2E).
• $40 million to the University of South Florida in 2025, the largest gift in its history, which named the Bellini College of Artificial Intelligence, Cybersecurity and Computing (WUSF).
• $11 million to create the Bellini Center for Talent Development at USF's Muma College of Business (WUSF).
• $7 million to Tampa Catholic High School in 2019 for a performing arts center, then the largest gift to a Catholic school in Florida (ChannelE2E).
• $5 million for the Live Wildly statewide conservation campaign in 2022 (Axios).
• $2 million to Saint Leo University in 2026 for an executive cybersecurity master's program (Business Observer).

These may overlap with the $70 million pledge, so they should not simply be added up. Still, no reliable outlet has turned any of this into a net worth figure, so we do not publish one.

Arnie Bellini's income

His income is not public. The old version of this page claimed $3 million a year, $300,000 a month and $10,000 a day, with no source; those figures have been removed. Since the 2019 sale, his money comes mainly from investments made through Bellini Capital rather than a salary. He also stayed on as an advisor to ConnectWise after the sale, according to ChannelE2E, but the terms were not reported.

How ConnectWise was built and sold

Wikipedia describes the sale as making ConnectWise the first Tampa Bay tech company to reach a $1 billion valuation. The old version of this page wrongly called him a "managing partner and CEO of ConnectWise" in the present tense; he has not run the company since 2019.

Bellini Capital and recent investments

Since the sale Bellini has run Bellini Capital, a family investment firm. After his non-compete ended he returned to the MSP software market. In 2024 CRN reported that Bellini Capital led a $9.2 million Series A investment in TechGrid, a quoting, procurement and billing platform for MSPs. By 2026 he was chairman of ConnectSecure, a cybersecurity company, according to Business Observer.

He is also the public face of "CyberBay," a push to make the Tampa Bay area a national center for cybersecurity through links between business, universities and the military. USF awarded him its President's Fellow Medallion at graduation in 2025, and Tampa Bay Wave named him its Tampa Bay Tech Legend the same year.

Recent changes (2025 to 2026)

• March 2025: The $40 million USF gift names the Bellini College.
• July 2026: USF's president tells the Tampa Bay Business Journal the Bellini College will get a prominent new building site on campus.
• August 2026: The $2 million Saint Leo gift funds a cybersecurity executive track, with its first class due in January 2027. Business Observer said the gift included $1.6 million in cash and about $400,000 in technology.

Assets and personal life

Axios reported in 2022 that he could afford a $9.25 million home on Clearwater Beach, and that he has lived near Avila in the Tampa area. Beyond that, no reputable outlet has published details of his property holdings.

Bellini is married to Lauren Bellini, a USF marketing graduate, and the couple have two sons, Arnold IV and Peter, according to USF. Axios gave his age as 63 in July 2022, which puts his birth around 1958 or 1959, and described him as a Republican. He graduated from Tampa Catholic High School and holds degrees from the University of Florida and a USF MBA. He is a long-distance swimmer: USF says he was the first person over 50 to swim the English Channel, in 2013. The height and weight on this page before had no source and have been removed.

His conservation work runs through the Live Wildly Foundation, which he founded. Axios reported that he led the effort behind the 2021 Florida Wildlife Corridor Act, which came with $300 million in state funding.

Why there is no reliable figure

A net worth estimate would need his ownership share of ConnectWise at sale, taxes on the gain, the size of his later investments and how much he has already given away. None of those numbers has been published. Pages that show a single figure, including the $76 million once shown here, do not say how they got it.
