Slyce vs Public: spend-to-own vs social brokerage

Slyce and Public both let you own pieces of public companies, but they're different categories of product. Slyce executes the rules you set when you spend. Public is a self-directed brokerage where you place orders. Same outcome (you own stock), different mechanic.

What each app is

Public is a self-directed brokerage with a social-investing layer^[1]. You open the app, search for a ticker, and place orders. Public has expanded into Treasuries, alternative investments (some of which are unique to Public among consumer apps), and crypto. The "social" piece is that you can see what other Public users hold and follow specific portfolios. Public Holdings, Inc. is the parent company; the operating brokerage entities are SIPC-member^[2].

Slyce is a spend-to-own app. Instead of placing orders, you set rules — when I buy at Starbucks, invest $1 in SBUX — and Slyce executes those rules automatically as eligible purchases happen. You don't pick tickers in the moment. Your spending picks them. Slyce charges $0 monthly subscription; revenue comes from payment-network rebates. Our investment adviser application is in progress under the Investment Advisers Act of 1940^[3]; you can look up any adviser on IAPD^[4].

The honest positioning: if you want to actively pick what you hold across multiple asset classes (stocks, bonds, Treasuries, alternatives, crypto), Public is the broader self-directed product. If you want spending to trigger ownership of brands you shop at, Slyce is the spend-to-own product. They're not better or worse — they're different categories.

How the two apps work

The funding event is where the divergence starts.

Public: deposit, pick, place. You transfer money in, browse Public's offerings (stocks, ETFs, Treasuries, alts, crypto), and place orders manually. Public also offers automated investing options, but the headline product is self-directed.

Slyce: spend, rule fires, fractional buy. You authored a rule. You bought coffee at Starbucks. Slyce identified Starbucks as the merchant, looked up SBUX as the public ticker, and per the rule you approved, executed a $1 buy of SBUX into your Slyce account. No order to place, no app to open in the moment.

Resulting portfolios diverge in shape. A Public user's portfolio looks like whatever they actively chose — sometimes diversified, sometimes concentrated, sometimes including bonds and alternatives. A Slyce user's portfolio reflects their actual spending — heavy on the brands they frequent, zero on brands they don't shop at.

Which is "better" depends on what you're optimizing for. Active selection is a real benefit (Public's positioning). Spending-driven ownership is also a real benefit (Slyce's positioning).

Where Public wins

Asset-class breadth. Public supports Treasuries, alternative investments (some unique to Public), and crypto in addition to stocks and ETFs. Slyce focuses on public-equity fractional shares. If you want one app for multiple asset classes, Public delivers breadth Slyce doesn't.

Active picking. If you actually want to research and pick specific positions — not just hold what you bought from — Public's self-directed model is the right shape. Slyce isn't a research platform; the rules you authored are the picks.

Social features. Public's social layer (following other portfolios, seeing transparency on what users hold) is a differentiated feature. Slyce doesn't have a social layer.

IRAs. Public supports Traditional and Roth IRAs. Slyce doesn't offer IRAs at launch.

Where Slyce wins

Zero subscription, zero commitment to active picking. Slyce's $0 monthly fee plus the per-purchase mechanic means you don't have to remember to invest. The portfolio builds itself based on your spending. The spend-to-own guide walks the long-term arithmetic.

Brand-specific ownership tied to your spending. If you buy from Apple, you own Apple. If you don't buy from a company, you don't own it. The portfolio matches your spending pattern by design.

Custodial accounts and Trump Account routing. Slyce offers custodial UTMA accounts and routes parent-directed deposits to a kid's federal Trump Account. Public doesn't advertise either. The Trump Accounts guide covers the federal program for kids born 2025–2028.

Auto-invest as the default. Public's auto-invest features exist but are optional layers on a self-directed app. Slyce's auto-invest is the core mechanic. If "I want investing to happen automatically without me picking tickers" is the brief, Slyce is built for it.

Where neither app wins

Neither app is a robo-advisor in the Wealthfront / Betterment sense. Public has automated investing options but doesn't run a managed-portfolio-against-a-target-allocation product the way a true robo-advisor does. Slyce doesn't either.

Neither app guarantees returns. Both carry full market risk; shares can go down. Neither registration status nor SIPC coverage prevents market losses.

Neither app replaces a full-service brokerage for power users. If you want options strategies, advanced screeners, or institutional-grade research, Schwab or Fidelity are the right tools.

Verdict

Pick Public if you want a self-directed brokerage with broad asset-class support — stocks, ETFs, Treasuries, alts, crypto — plus social features and IRAs. Public's range is genuinely wider than Slyce's, and self-directed control matters if you want to pick specific positions.

Pick Slyce if you want spending to trigger ownership of brands you shop at, you'd rather not place orders manually, you need custodial accounts, or you're a parent in the 2025–2028 Trump Account window. The zero subscription compounds, and the spend-to-own mechanic is fundamentally different from active picking.

If neither answer is satisfying, the two apps run side by side without conflict — Public for active asset-class diversification, Slyce for the spend-to-own layer. That's a legitimate setup.
