Fractional CFO for consumer internet companies

Consumer internet businesses live or die on cohort behaviour. Retention curves, ARPU mix, payback period and the share of revenue coming from the top decile of users tell you whether the product is compounding - or whether paid acquisition is masking a leaky bucket.

Generic finance functions tend to report DAU, MAU and revenue, and call it a day. That is not enough when the difference between a venture-grade business and a slow-fade app sits in the slope of the retention curve and the contribution margin per cohort. A fractional CFO who has read those numbers across dating, social, content and gaming knows what good actually looks like.

We work with consumer founders across the spectrum, and bring the cohort and unit-economic lens that turns dashboards into decisions about pricing, paid spend and product investment.

Choose a fractional CFO that understands consumer internet

Why choosing a CFO with strong understanding of consumer internet is so important for your startup.

Cohort math, properly done

LTV, payback and retention need to be measured cohort by cohort, channel by channel - not as blended averages that hide the truth. We build the cohort waterfall and the contribution margin view that show which acquisition mix is actually creating value, and which is buying revenue at a loss.

ARPU and monetisation mix

Subscription, in-app, ads and one-off purchases each carry different gross margins and very different durability. We model the ARPU mix and contribution per surface, so the team can decide where to push pricing and where to leave free behaviour alone.

Paid spend with a leash

Consumer P&Ls move fast when paid social budgets get loose - a great week on CPI can turn into a bad quarter on payback. We sit between the growth team and the bank balance, putting weekly guardrails on spend tied to actual contribution rather than headline ROAS.

Built for venture review

Consumer VCs underwrite cohort retention, ARPU progression and a credible engagement story, not GMV vanity. We package the metrics in the form the funds backing consumer at your stage already expect, so the next round opens on numbers, not on a re-education exercise.

Financial modelling for consumer internet startups

We work with consumer internet founders to build investor-ready, KPI-driven financial models.

We dive deep into your company and sector specifics, to build a custom-made financial model driven by operational KPIs, requiring a minimal learning curve and time spent on monthly updates.

Cohort retention curves

Retention measured cohort by cohort and channel by channel, not as a blended average that hides the truth. Shows whether the product is compounding or whether paid spend is masking a leaky bucket.

LTV/CAC by channel

Lifetime value modelled against fully-loaded acquisition cost across paid social, search, referral and organic. Tells you which channel mix is creating value and which is buying revenue at a loss.

ARPU & monetisation mix

Subscription, in-app, ads and one-off purchases split out by surface and cohort. Decides where to push pricing and where to leave free behaviour alone.

Paid spend guardrails

Weekly spend ceilings tied to actual contribution rather than headline ROAS. Sits between the growth team and the bank balance when CPI gets volatile.

Engagement to revenue bridge

DAU, MAU and session metrics tied to ARPU progression and contribution per active user. Shows which engagement metric actually predicts revenue and which is dashboard decoration.

Top-decile user economics

Revenue and engagement concentration in the top 1, 5 and 10 percent of users, modelled separately from the long tail. Most consumer businesses live or die on this slope.
