Fractional CFO for WealthTech companies

WealthTech revenue scales with AUM or AUA, which makes the model sensitive to flows and market moves at once. Management fees, platform fees, advisory fees and product-level economics from cash sweep and securities lending each have to be recognised correctly, and the line between revenue and pass-through custody or fund expenses determines whether gross margin is credible. Regulatory capital under SEC, FCA or local rules sits alongside the operating accounts.

The work turns on the AUM-economics layer. AUM and AUA reconciled to custody statements; net new asset tracking by channel; fee yield by product and client segment; unit economics of an advised client versus a self-directed one; and the working and regulatory capital required to operate a custody and brokerage stack. Cash sweep and securities lending revenue need to be visible as separate lines because acquirers price them differently from management fees.

Flow provides financial modelling, FP&A and fractional CFO advisory to WealthTech companies across robo-advisors, digital wealth platforms, advisor technology, alternative investments platforms and retirement and pensions technology.

Financial modelling for "WealthTech" startups

As fractional CFOs, we build KPI-driven financial models that are insightful and easy to maintain.

Financial modelling is both art and science - models must be robust, but also understandable, and useful for both internal planning and VC fundraising purposes. Hire a fractional CFO who knows how to handle both sides of the equation.

AUM and net new asset waterfall

Opening AUM walked to closing via net new assets, market moves and outflows, with NNA cut by channel, client segment and product. Separates flow-driven growth from market beta the business does not control.

Fee yield by product

Blended fee yield in basis points decomposed by managed portfolio, advisory tier and product line, with the structural drift from premium to passive surfaced. The metric boards use to spot quiet margin compression before it shows in revenue.

Cash sweep and securities lending

Revenue from uninvested customer cash and securities lending modelled as standalone lines against the rate curve and inventory available to lend. Acquirers price these very differently from management fees and they need their own visibility.

Client unit economics

Revenue per advised client versus self-directed, against acquisition cost, advisor cost where applicable and platform cost. Tells the board which client tier earns its CAC and which is being subsidised by another.

Custody and operating cost stack

Custody, clearing, market data and platform infrastructure costs allocated against the revenue lines they enable. Distinguishes platform gross margin from advisory gross margin since they support different valuations.

Regulatory capital and net worth

SEC, FCA or local regulatory capital requirements tracked alongside operating equity, with stress scenarios for market drawdowns that consume capital while compressing fee revenue. The headroom that prevents a downturn forcing a capital raise.
