SigFig vs Zoe Financial: Which Is Better in 2026?

Figures and features are point-in-time and change; treat the table as a starting map, not a live quote.

An automated investing service that manages accounts held at your existing broker rather than requiring you to move money.

How it works: Rather than opening a new account, you link an existing brokerage account at a supported custodian and SigFig manages it in place, rebalancing and running tax-efficient strategies. Below a stated balance the management is free. This structure is unusual: nearly every competitor requires custody of your assets.

In practice, SigFig’s AI automates a portfolio in accounts you already hold. It falls under hands-off automated investing (robo-advisors), which makes it best suited to automation that manages your existing schwab or fidelity account. On connecting an account it is “Yes, it manages accounts held at supported brokers”, and on execution it is “Automated”. It is priced as free under a stated balance, then a percentage (verify current).

One honest limitation: Supported custodians are limited, so it only works if your account is already at one of them.

A matching service that connects you with vetted, fee-only fiduciary advisors, free to you because advisors pay for the introduction.

How it works: You answer questions about your situation and Zoe proposes advisors from its network, which it screens for fiduciary status, fee-only compensation and credentials. You interview them and hire directly. Zoe is paid by the advisors, which is why it costs you nothing and why the pool is limited to firms that joined.

In practice, Zoe Financial’s AI none; it is a matching service. It falls under hands-off automated investing (robo-advisors), which makes it best suited to being matched to a vetted fiduciary advisor. On connecting an account it is “No (the advisor you hire manages assets)”, and on execution it is “Advisor-managed”. It is priced as free to you; the advisor pays for the introduction (verify current).

One honest limitation: You are matched from the network that pays to be in it, which is a smaller pool than the whole profession.

The core difference is category. SigFig focuses on automation that manages your existing schwab or fidelity account (automates a portfolio in accounts you already hold), and Zoe Financial on being matched to a vetted fiduciary advisor (none; it is a matching service). On broker connection they differ too: SigFig is “Yes, it manages accounts held at supported brokers” versus Zoe Financial at “No (the advisor you hire manages assets)”. That shapes everything downstream: how personal the answers are, where trades settle, and how much control you keep over individual positions.

Every tool gives something up for what it does well. Here is the honest give-and-take on each, so you can weigh the specific strengths against the limitations that come with them rather than judging on the headline category alone.

For AI investing tools, the distinction that matters most is whether the tool works from your actual, connected positions or reasons from something else: a separate account it manages for you, or the tickers and numbers you feed it. It decides how personal the answers can be, and where your money physically lives.

• SigFig: manages a separate account it holds. SigFig does not read the brokerage you already use. It opens and holds a new account, then invests the money you move into it, so its view is limited to what sits inside SigFig.
• Zoe Financial: manages a separate account it holds. Zoe Financial does not read the brokerage you already use. It opens and holds a new account, then invests the money you move into it, so its view is limited to what sits inside Zoe Financial.

On this specific question the two land on the same side, so the deciding factors between them are elsewhere: category, cost, and who each is built for. This holdings-aware angle is the one Walnut is built around: it connects the brokerage you already use and reasons from your live positions, read-only by default, with any trades left for you to approve.

There is no universal winner here; the right pick depends on the job you are hiring the tool for. Match the category to your intent rather than chasing a single “best.”

• Choose SigFig if you want automation that manages your existing schwab or fidelity account. Its AI automates a portfolio in accounts you already hold, it is priced as free under a stated balance, then a percentage (verify current), and it fits hands-off automated investing (robo-advisors). It is built for someone with an existing account at a supported broker who wants it managed without moving anything. Keep in mind that supported custodians are limited, so it only works if your account is already at one of them.
• Choose Zoe Financial if you want being matched to a vetted fiduciary advisor. Its AI none; it is a matching service, it is priced as free to you; the advisor pays for the introduction (verify current), and it fits hands-off automated investing (robo-advisors). It is built for someone who has decided they want a fee-only fiduciary and would rather start from a screened shortlist than a directory. Keep in mind that you are matched from the network that pays to be in it, which is a smaller pool than the whole profession.

Because both sit in the same category, the choice comes down to the finer details above rather than a fundamental difference in approach.

Cost is easy to misread when two tools charge in different shapes, so compare the model, not just the number. SigFig is priced as free under a stated balance, then a percentage (verify current), while Zoe Financial is priced as free to you; the advisor pays for the introduction (verify current). A percentage-of-assets fee scales with your balance, a flat subscription does not, and a “free” tier usually earns elsewhere (on cash, order flow, or premium upgrades), so the cheapest headline is not always the cheapest outcome for your situation.

Pricing and tiers change often. Confirm the current numbers on each provider’s own site before you decide; the framing above is point-in-time.

If neither quite fits, Walnut sits in a third category: chat-driven management of your own brokerage. It connects the brokerage you already use through SnapTrade, lets you analyze and manage it by talking through Claude or ChatGPT, build thematic portfolios around a thesis, and place trades you approve. Read-only by default. See Walnut vs SigFig and Walnut vs Zoe Financial. Walnut is not an investment adviser.
