News, Vision & Voice for the Advisory Community
The New York City startup unveiled itself yesterday as an all-in, 'AI-native,' wunderkind that is in the process of 'removing' applications and shedding its old Schwab custody and robo-investing ties — and gets ex-Schwab CFO Peter Crawford as backer.
Brooke’s Note: Savvy and Farther both got off to great starts simply by being startup RIAs where the technology gets built with the fervor of a Silicon Valley unicorn by people with engineering degrees from the finest schools. Arca Wealth is the latest to do the same. It has gone from Stealth mode to viral (among RIA cognescenti) in less than 48 hours. It’s almost as if it’s trying to impose crushing expectations onto itself with its claims, mission and testimonials. We like self-esteem and pedigreed minds around here, and all that self-assuredness stirs the drink of a more generally humble industry. The idea is that both RIA technology and RIA rollup design flaws can both be solved by using AI mixed into the cement of the foundation of a new startup – combining seasoned analog New Hampshire advisors with the most digital Anthropic-beloved talent — with AI doing everything, except talking to clients. We have three sources – two on record and one off – who push back pretty hard against the idea this is an RIA design breakthrough. But abject entrepreneurial AI belief and zeal, combined with eye-rolling from veterans who have seen and heard it all before … it’s why we write the stories. I like seeing the skeptic proven wrong, even if I’m one of them.
Arca Wealth burst onto the RIA scene yesterday as the perfect aggregator – vaporizing all traces of legacy software and custody relationships – morphing its molecules into a single cell powered by big-brain artificial intelligence (AI).
As part of that move, Arca yesterday (June 25) announced – both by a press release and an Wall Street Journal “Pro” section article — a new $48.5 million raise (bringing the total to $60 million). The raise was led by General Catalyst, which owns an Anthropic stake through its H round.
CEO Rron Rexha, started the company in January a year ago, before he turned 30 and now has $1 billion-plus in assets held mostly at AI partner Altruist.
“Rron and Arca are on the cusp of something revolutionary in wealth management,” said Nick Beim, partner at Venrock, which bought a stake in the latest round.
Critics say it is still a rollup at heart, and all that transformative AI just keeps advisors captive as much as it improves their efficiency – and many ways exist to skin the AI cat without being AI-native.
Michael Kitces, XY Planning Network founder and authoratative RIA blogger, doubts that Arca has invented a new category because it may not be able to apply AI in a way that changes the game.
“My impression is that ultimately it’s another player in the category of, ‘If we build our own internal all-in-one native technology stack, we can make our advisors drastically more productive and that will result in a valuable enterprise’, which is a substantively similar story to Farther, Compound Planning, etc. (and Facet Wealth, for that matter),” he says by email.
Rexha declined to be interviewed for this article, but speaks with shimmering idealism about the financial tranquility he plans to deliver with Arca.
“Everyone deserves the peace of mind that your advisor sees you, hears you, and intimately understands the entirety of your financial ecosystem,” he’s said.
Jahanvi Sardana, partner at Index Ventures, an investor in the A round, says RIA technology is virtually unchanged since 2006 – giving Arca chance to close a massive gap.
“Wealth management is one of the last places where technology has barely moved in twenty years, while the customer has changed completely.
“Rron understands that gap better than anyone we’ve met – Arca is being built for how people actually want to manage their money. We’re thrilled to be backing him.”
Altruist wins 'unsolicited' $152-million raise, including capital from Salesforce, which is midstream 'very deep integration' signalling shift to $1-billion-plus RIAs
Rexha founded Arca in Jan. 2025, two years after quitting Plaid. Until now, he operated in stealth mode, quietly raising $15.5 million from Venrock in a seed round.
Though multiple RIAs, wealth managers and wealth technology startups make promises, Arca is truly different in at least one respect, says Altruist Founder and CEO, Jason Wenk.
“The Arca platform is incredible, it’s effectively a collection of AI agents designed to replicate human work without a traditional interface,” he says. “There is nothing like it in the industry, including how their agents can directly write to Altruist‘s back-end APIs.
“Unlike others, who rely on legacy thinking and operations (such as choosing traditional vendors), Rron builds things from scratch, the right way,” says Wenk who custodies most of Arca’s assets through Altruist. Fidelity Investments and Schwab Advisor Services are secondary custodians, he says.
Joel Bruckenstein, producer of the T3 technology conferences, says he sees potentially significant downside for advisors who are plugged into such a single-vendor ecosystem.
“It sounds like a new iteration of the independent broker-dealer market,” he says. “You’re semi-captive.”
Bruckenstein adds that existing RIAs can – and are – effectively applying AI to their practices. Schwab has an ongoing “road show” underway that is attracting hundreds of firms in places like Newport Beach and New York City – with another planned for Chicago in August.
He believes larger RIA firms with billions of AUM can hire firms like Subatomic AI and Field to make them AI efficient. For smaller advisors Arca may be an attractive option, he says.
Altruist CEO Jason Wenk says he was caught off guard in Mexico when his firm's 'DeepSeek' moment triggered a 'Big 3' Wall Street meltdown, but his AI revolution is only beginning, he tells RIABiz

One wealth manager principal who asked to remain anonymous to speak freely says, for now, AI is more a part of the startup narrative than its real-world execution.
“The growth story is acquisition, not AI,” he says. “Per the ADV, Arca was seeded through Granite Bay Wealth Management and then bought Sandbox Financial Partners (~$682M) in May.
“Add those two books and you’re at the “$1 billion-plus. There’s little to no organically AI-generated AUM yet, which is why the ADV reads like a conventional RIA. It is one, for now.”
Wenk disagrees and says its organic growth is also substantial. Arca managed approximately $1.27 billion in client assets, as of Dec 31, 2025.

“Separate from inorganic growth, their organic growth rate is astounding, especially for a firm of their size,” he says. “Much of this is due to the high degree of automation gained from their proprietary technology and Altruist‘s efficiency.”
The Arca AI-rollup business model is largely a knock-off of one it applied to other fragmented industries by its chief financier, according to the wealth manager. General Catalyst’s “Creation Strategy,” is an AI-enabled roll-up model applied to wealth, the source says.
“It’s the same structure as Eudia in legal (which bought a 300-person legal team), Titan MSP in IT (which bought RFA), and Long Lake (18 acquisitions across home and business services). Structurally, it’s a classic PE roll-up but with AI-led branding to differentiate.”
Still, Wenk stresses that not all AI is created equal, and that Arca, with 28 employees, stands out for orchestrating its use on behalf of wealth managers.
“Rron is exceptional,” he says. “There’s truly no one like him in our industry. He could be working in a meaningful role at a leading AI lab like OpenAI or Anthropic, but he is choosing to reinvent wealth management.
“He attracts talent that would normally have little to no interest in wealth management. He combines all of this technical know-how and vision with an incredible sense of humility.”
“Can a well-funded RIA with great engineers build their own proprietary tech that actually results in materially higher productivity (and ostensibly, better margins for their owners/investors)? Kitces asks
“The question is whether and where the productivity will show up. Some suggest it’ll be an ability for advisors to take on more clients, though as our Kitces Research on Advisor Wellbeing has repeatedly found, advisors don’t want or enjoy an unduly large client base… even with great tech, it leads to cognitive overload, burnout, and turnover.”
Though everyone deserves the peace of mind that Rexha talks about, it will require $500,000 of assets minimum to get it from Arca. In most cases, financial planning is an extra charge, according to the ADV.
Fees range up to 1.5% and financial planning fees range up to $300 per-hour, but are free for clients paying based on managed assets.
The ADV also details a Schwab relationship that includes Schwab Intelligent Portfolios (SIP) (its robo-advisor) for investment management. Arca sources say the company no long uses SIP. Wenk adds that Altruist will become exclusive custodian in the near future.
“When advisors join their firm, or if they acquire a firm, they often come with a prior custodian. But the Arca AI platform integrates directly with Altruist APIs so the intent is to migrate all of historical accounts to Altruist within a few months.,” he says. “They also send all new accounts to Altruist.
Wenk adds: “Much like some of the advisors and RIAs had legacy custodians, they also had legacy technology. That all gets sunset after migration to Arca and the entire tech stack will be just Arca and Altruist.”
“So big questions here about how far this can go. Others suggest it’ll come from a deeper value proposition for clients, which tries to lift the firm’s productivity through higher pricing as a premium experience,” says Kitces.
“From our research, I think the latter is the more likely outcome for whoever succeeds here… the arc of technology in the advisory business for decades is that it leads to effectiveness (and pricing power) more than efficiency (and increased client loads).”
Still, Arca has some impressive board members and advisors; among them are Ex-Schwab CFO Peter Crawford and Bill McNabb, former CEO and chairman of Vanguard Group who says that Rexha has cracked the code by combining humans and AI.
“Rron understands that AI can help power the mechanics behind wealth management – but the financial advisor is ultimately the driving engine,” said Bill McNabb, former CEO and chairman of Vanguard Group.
“The role of the advisor is paramount, and it’s what creates real, long-lasting impact. AI can help us do our jobs better, but it will never supplant the humanity of this profoundly personal profession. Arca uniquely balances embracing AI while empowering advisors as our true financial custodians.”
