Stock investing
Everyone breaks at the same place: when money is on the line.
The niche splits into four kinds of demand. Beginners are sold simplicity (, ), but the app keeps crashing and especially on the way out, and it can even drop an order into the red. Serious brokers get paid for depth (Fidelity, ), yet the mobile app lies about cash and freezes. Robo-advisors are trusted with the do-it-for-me mode (Betterment, ), and that trust collapses at withdrawal: the money takes months to arrive, the account is suddenly under review.
The mechanism is the same. The app gets opened at a tense moment: a trade, a withdrawal, a market drop. That is when it has to be fast, honest about the numbers and clear. And that is exactly where the leaders sag.

- The money here is in subscriptions and fees, not in per-trade commissions. Basic trading at , Fidelity, is free, and against that backdrop paid plans have to justify themselves. charges monthly, Stash around 12 dollars a month, + up to 14.99 a month with a markdown to 4.99 when you try to cancel, 120 dollars a year. Betterment and live on a percentage of assets. A separate layer is data and signals: level II quotes, scanners, analytics and lessons. Active users pay for these readily if the tool genuinely saves time. What hurts most are costs at the wrong time: a 100-dollar account transfer fee, charges after a subscription is cancelled, ads over a chart that was already paid for.

Gamification brokers (, ) win with an easy entry and learning. They sag on reliability: they freeze right after a purchase, crash on the way out, give murky execution prices, and can restrict an account. Classic brokers (Fidelity, Schwab, ) win with depth and coverage. They sag on the freshness and stability of the mobile app: cash and positions are shown wrong, the app freezes and crashes, the interface is slow and outdated. Robo-advisors and round-ups (Betterment, , M1) win with the do-it-for-me mode. They sag at the money exit: for months people can't get their funds out, the account is placed under review. Trackers and AI signals (, ) win with analytics. They sag on data accuracy (numbers wrong, not updating) and on trust in the crowd's signals.
Audience
"Stock investing" is not one customer. Inside are different people with different jobs, and they pay very differently. First you choose who you build for.
Where the money is
The niche stratifies by experience and by number of accounts. The beginner wants understanding and a gentle price. The trader pays for speed. The passive investor pays for calm. The multi-broker investor pays for a whole picture. The money goes where the app removes friction and anxiety at the deciding moment, not where there are simply more features.
