AUM — assets under management — is the number the investment industry brags with, prices by, and lives or dies on. Once you can read AUM the way an analyst does, platform press releases, adviser pitches and our own Platform Reports all become clearer.
The definition and the fine print
AUM is the total market value of assets a firm manages on behalf of clients. The fine print is what counts as “manage”: regulatory AUM (the Form ADV number — how to find it) has a legal definition, while marketing AUM sometimes bundles assets merely administered, advised on, or sitting in cash accounts. Same firm, two numbers, and the press release always picks the bigger one.
Why it’s the industry’s oxygen
Because fees are mostly a percentage of it. A firm charging 0.25% on $1B grosses $2.5M; on $100M, $250K — which won’t pay for compliance, engineering and marketing. That single relationship explains our entire graveyard: platforms with beautiful products and sub-scale AUM are companies on a countdown, however registered and legitimate they are. It also explains behavior — why platforms push deposits relentlessly, pay transfer bonuses, and hate withdrawals: your balance is literally their revenue base.
Reading AUM like a skeptic
Three moves. Divide AUM by number of accounts (both in the ADV) for the average client — it tells you who the platform really serves regardless of the ads. Compare AUM to headcount and funding: 40 employees on $35M AUM was Swell’s death certificate arithmetic. And watch the trend across filings, because AUM rises two ways — new client money or market gains — and only one of them means the business is actually winning customers. A growing market lifts every AUM chart; the filings show which platforms would grow in a flat one.
