On paper, paying taxes sounds simple. Money goes out, problem solved. In practice, it is where things break. Filings get separated from payments. Deadlines slip. Penalties appear months later, often after everyone involved thought the job was done.
That gap, between filing and payment, is where Solon Angel has spent most of his career looking, even before most people thought it was a problem worth solving.
Angel has built and fixed companies across continents, industries, and tech cycles. Born in Brazil, raised in France, educated across Europe, he cut his teeth early, joining Dell before jumping into startups in his early twenties. Canada came next, where he spent 15 years deep inside the accounting software world, working with one of the largest global vendors and later turning around an early AI video surveillance company.
But the pattern that kept pulling him back was accounting. More specifically, what happens after the return is filed.
“I wanted to use pure AI,” Angel said, describing the moment that led him to found MindBridge, an early AI auditing company launched a decade before the current hype cycle. “That was ten years ago, before AI was in fashion,” he said. MindBridge would go on to earn global recognition and eventually exit in a nine-figure transaction.
Angel could have stayed on the investor side after that. He tried. It did not last.
“As an entrepreneur, investing gets boring,” he said. “I wanted to go back into doing something meaningful.”
That pull led him to Remitian, a Miami-based accounting technology company focused on a part of the tax process most people barely think about: remittances. Angel got involved three years ago, when the product was still incubated inside an accounting firm with strong demand but no clear path forward. What stood out to him was not the product itself, but the problem underneath it.
“Tax payments are a compliance event,” Angel told Refresh Miami. “It’s not just sending money. There’s a filing attached, checks that need to happen, registrations with authorities. Without AI, there was no way to do what Remitian does.”
The platform acts as connective tissue between tax software, accounting firms, banks, and government systems. Angel compares it to what Stripe did for online commerce, but applied to tax. Firms can embed Remitian into their workflows through an API, while an AI layer routes payments, manages filings, and handles the rules that change from one jurisdiction to the next. Behind the scenes, Remitian is registered directly with tax authorities, including the IRS, and partners with major banks like Wells Fargo to power the underlying infrastructure.
CPA firms use Remitian to avoid late fees and angry calls from clients who assumed everything was handled. Accounting tech startups embed it to complete their product stack. Wealth managers use it to offer a more controlled, white-glove experience. What connects them is visibility. Before Remitian, Angel said, firms delivered filings and hoped clients paid on time. When they did not, the blame came back anyway.
At the same time, the rest of the tax world is shifting fast. Basic returns are being automated away by AI-driven platforms. “CPA firms have lost leaders,” Angel said. “Low-margin work like 1040s is being commoditized.” That makes the operational side of tax, payments, compliance, proof, more valuable, not less. Someone has to make sure everything actually happens.
Remitian officially went to market last spring, just as the company relocated leadership to Miami. Today it has 32 employees, with the commercial team centered in South Florida and engineering spread across Canada and Brazil. The move has paid off quickly.
“We did 10x since we arrived in Miami,” Angel said. “We doubled our fundraising. Our seed round closed extremely fast.” Remitian has already brought on some significant backers, including an investment from tax giant Aprio CEO Richard Kopelman, and is set to announce the closing of its seed round soon.
“If you draw a triangle between North America, South America, and Europe, Miami is right there,” he said. He also noticed a pattern of accounting tech founders, payments founders, and fintech operators relocating to the region.
That seriousness shows up in Remitian’s traction. Large national accounting firms are rolling it out across tens of thousands of taxpayers. Industry veterans have joined the board. Well-connected fintech investors moved quickly once they understood the scope of the problem being solved.
“This is growing three times faster than my last company,” Angel said, referring to MindBridge. “If it doesn’t become something very big, I’d be surprised.”
Whether Remitian becomes independent infrastructure or gets absorbed into a larger platform remains to be seen. Angel is not rushing that question. The work right now is execution, scaling into new countries, and making sure the least glamorous part of taxes never breaks again.
