Fractional CFO for data infrastructure companies

Warehouses, lakes, pipelines and observability businesses are consumption-led. Customers pay for compute, storage and data movement, and infrastructure cost scales directly with usage. Reserved capacity, committed-spend discounts and credit-based pricing add accounting nuance that doesn't exist in seat-based SaaS.

Cost-of-revenue reporting attributes infrastructure spend to the customers and workloads driving it, not averaged across the customer base. Customer commitments, credits and ramp deals are tracked so the bridge from bookings to revenue stays accurate through the multi-quarter consumption ramps these contracts include.

Flow provides financial modelling, FP&A and fractional CFO advisory to data infrastructure companies across data warehouses and lakehouses, data integration and ETL/ELT, streaming and event infrastructure, vector and feature stores, and data observability and lineage. We work as the outsourced startup CFO through growth, fundraising and sale processes.

KPIs to track for "data infrastructure" startups

We're very 'KPI-driven' fractional CFOs, and we make sure to monitor the right metrics for your startup.

Consumption revenue

Net retention

Committed-spend backlog

Active customers

Compute / storage units

Gross margin

Workload growth

Customer concentration

Ramp realisation

CAC payback

Financial modelling for "data infrastructure" 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.

Consumption ramp model

Multi-quarter ramp deals modelled per customer with credit-burn curves, true-up events and overage assumptions. The bookings-to-revenue bridge stays accurate through the long consumption ramps these contracts are built around.

Committed-spend backlog

Committed-use credits, reserved capacity and ramp deals tracked as contracted backlog with realisation rates by cohort. Gives the board a defensible view of how much of next year's revenue is already underwritten by customer commitments.

Infrastructure COGS attribution

Compute, storage, egress and reserved-capacity costs attributed to the customers and workloads driving them rather than averaged across the base. Surfaces the customers where heavy queries are quietly dragging gross margin into the teens.

Workload-level retention

Net retention modelled at workload and use-case level - ETL, warehouse, streaming, lakehouse - because consumption can grow in one workload while another silently churns. Aggregate NDR hides the substitution risk that matters.

Reserved capacity and credits accounting

Customer credits, ramp deals and committed-use discounts modelled through P&L and balance sheet with deferred revenue treatment matched to actual consumption. The recognised-revenue path stops surprising the board at quarter-end.

Cap table and dilution scenarios

Pre/post-money cap table with SAFE conversions, option pool refreshes and conversion under consumption-multiple exit cases. Founders see dilution against the realistic ARR-equivalent trajectory rather than headline consumption growth.
