Fractional CFO / FD for funded startups

Build the finance function investors expect.

We provide Fractional CFO and FD support for funded seed-Series A scaleups, so you can focus on growing a business you love.

Who we serve

Two stages, one underlying problem.

In both cases, the finance function hasn't kept pace with the business - and someone external needs to close that gap fast.

Primary

Seed-Series A funded startups

In any sector - the common thread is needing investor-grade numbers before the round closes, not after.

Secondary

Growth-stage scaleups, 15-100 staff

Facing a first audit, a board's first real reporting requirements, or deciding whether it's finally time to hire a CFO - and what that role should actually look like before you commit to it.

Services

Two areas of focus.

Project fees to set the foundations, a retainer to keep them running once they're built.

Finance function setup

Foundational

Finance architecture

Chart of accounts design, reporting framework, controls & governance, accounting software selection (Xero, QuickBooks, NetSuite, AccountsIQ), bookkeeping process setup.

Reporting

Investor-ready reporting

Revenue

Revenue recognition

About

Karen Charman

Mariposa Consulting was founded by Karen Charman, a fractional CFO who spent six years inside Sister Group's portfolio of media and entertainment businesses before going independent.

Earlier in her career, she worked at FremantleMedia in Fremantle Enterprises - the division responsible for exploiting rights beyond the productions themselves: merchandising, telephony, interactivity, sponsorship, and events.

Sister Group invests across TV and film, digital-first production, podcasting, publishing, and music and live experiences. Karen was Finance Director for two of the portfolio companies and partnered closely with founders, CEOs and senior leadership of the rest, who reported into Sister Group as their investor.

Karen also spent two years as acting VP Finance for Sister US Productions, the sole finance lead business partnering the CEO. Most development spend never becomes a greenlit show, so much of the role was managing cashflow and risk across a slate and deciding what to write off. There was no existing finance infrastructure, so she built the processes, chart of accounts and controls herself.

At group level, Karen was Global Head of Group FP&A: she ran the planning cycle across Sister Group's multi-entity portfolio - the annual budget, rolling forecasts and long-range plan - consolidating inputs from each portfolio company into one group view. She owned the KPI framework and management reporting pack for the exec team and board, acted as commercial finance partner to the CEO and CFO, and rolled out systems that cut days off the monthly consolidation process.

Mariposa now applies that same playbook - investor-ready reporting, revenue recognition, fundraise readiness - to founders building finance functions of their own, in media and beyond.

Why Mariposa? It's Spanish for butterfly - a fitting namesake for the transformation between a seed round and a Series A, and the one Mariposa exists to support.
