AI operating system race heats up as Nevis raises $70 million
Tandems and Zeplyn roll out new AI agents and assistants as wealthtech firms compete to run more of advisors’ back-office work
OCT 29, 2026

Nevis, a New York-based AI operating system provider for wealth management, has closed a $70 million Series B round led by EQT Ventures, bringing its total funding to $110 million.

Schwab has joined as a strategic investor in the AI startup, along with QuantumLight, the fund of Revolut founder and CEO Nik Storonsky. Existing backers Sequoia Capital, ICONIQ and Ribbit Capital all increased their commitments.

The company's business has grown at a parabolic pace. Nevis said assets on its platform rose to $700 billion from $50 billion in 2026 and are currently growing by about $75 billion a month. It said revenue has increased more than 25-fold over the same period, with a client base that includes Focus Financial Partners, IEQ Capital and United Capital.

The platform combines CRM, meeting intelligence, financial planning and custodial workflows in one system. Nevis said its agents have completed more than 100,000 operational tasks. By the company's estimates, advisors using the platform get back up to 10 hours a week, hold 30% more prospect meetings and are able to open accounts in days instead of weeks.

“Our investment in and partnership with Nevis expands that ecosystem, helping advisors harness AI to operate more efficiently, increase their capacity and ultimately serve more investors,” said Jon Beatty, head of Schwab Advisor Services.

Carolina Brochado, partner and head of EQT Ventures, will join the Nevis board. 

Tandems pushes past the AI notetaker

San Francisco-based Tandems, which until last year was operating as SigFig, has launched Hamilton, an assistant built into its WealthOS platform. The company says Hamilton can handle up to 80% of an advisor’s daily tasks, including financial planning, portfolio rebalancing, meeting preparation, account opening, asset transfers and paperwork.

“When you dig into AI products for financial advisors today, what you get are largely notetakers. Hamilton actually makes wealth advisors more efficient and more impactful for their clients, rather than summarizing what needs to be done,” said Mike Sha, co-founder and CEO of Tandems.

As Tandems explains it, Hamilton brings together seven systems and 45 tools within WealthOS, with a Model Harness Optimizer capability sending each task to the best-suited model among Anthropic’s Claude, OpenAI’s ChatGPT, Microsoft Copilot and Google Gemini, as well as the option for firms to also connect their own models. Built-in connections cover Schwab, Fidelity, National Financial, Pershing, FIS, Fiserv and Salesforce.

Tandems is also selling on its controls, highlighting Hamilton's ability to adjust conversations to meet state AI laws and keeps a full audit log of every AI-assisted client interaction. Firms can shut off a single skill, a single model or all AI activity in real time.

Tandem's new features are arriving as the SEC’s Division of Examinations has named super intelligence among its 2027 exam priorities, with focusing on policies pertaining to fraud detection, back-office work, AML and Reg BI compliance, and trading.

More than 5,000 advisors reportedly use Tandems, at firms including Wells Fargo, Scotiabank, Citizens and New York Life. The platform reports $80 billion in assets across 2.7 million accounts. 

Zeplyn takes AI agents into the back office

New York-based Zeplyn introduced Zeplyn Workflows, which turns a firm’s operating playbooks into multistep processes that run across systems and departments. Among several target uses, it identified advisor transitions, client onboarding and account opening.

The product runs on Zeplyn Agent Nexus, the AI orchestration engine it launched earlier this year. Each workflow records an owner, a status and an activity history, and it pauses at points the firm sets so a designated person can approve the next step.

AI agents interpret information and choose next steps within set limits, while rule-based actions validate data and update systems. The product uses more than 50 wealth-specific agents and connects to more than 30 advisor systems.

The rollout of Zeplyn Workflows follows the company's launch of its Agent Studio and companion MCP server just last month.

“An advisory firm should be able to tell its AI how it operates and expect the work to get done, and with Zeplyn Workflows, that’s possible,” said Era Jain, co-founder and CEO of Zeplyn.
