Preparing a funding round? Finance before Series B/C: roles, scope and cost factors.

From portfolio need to a concrete finance engagement

We start with the next board deadline, the last reconciled close and the decision the forecast needs to support. Together with management, we agree the role, initial deliverables and handover.

  • After the funding round: bring plan assumptions, hiring budget and reporting calendar together.
  • When runway is unclear: liquidity plan with base and downside scenario, documented assumptions and actions.
  • Before the next board meeting or fundraising: align financial model and KPI dictionary, explain variances and prepare financial documents.

Typical results are an aligned board pack, a traceable runway plan and clearly assigned tasks. In a portfolio comparison, different business models and KPI definitions remain visible.

Operational support for your finance team

For overdue accounts, interim accounting prioritises entries and reconciliations, producing a backlog register and close calendar. For uncertain planning, FP&A documents drivers and builds base and downside scenarios. If finance leadership is missing, an interim CFO takes responsibility for priorities and handover.

In brief

Last updated: 13 September 2026

nugrow supports tech scale-ups and VC-backed companies as they develop their finance function. The CFO leads finance, accounting provides the agreed actual figures, and FP&A connects them with growth drivers, cash and planning. The operational engagement is agreed with management; investors receive the agreed reports.

  • Triggers: scaling after Series A or B, a CFO or accounting vacancy, establishing FP&A, the next funding round or an upcoming board meeting.

  • Models: ongoing CFO as a Service or a fixed-term interim CFO; CFO support at nugrow starts at EUR 1,800 per day excluding VAT, with an agreed workload.

  • Services: interim accounting and closing preparation, interim FP&A, budgets and forecasts, runway planning, KPI alignment and board reporting.

  • Experience from VC-backed companies: Sebastian Janus has worked as interim CFO at Staffbase and Papershift, among others. Across all twelve mandates, seven private-equity firms and venture-capital investors sat on the shareholder side — including Insight Partners, eCapital, AEM Capital and BayBG. The reference overview describes the brief and scope of each mandate.

Experience from 350 projects.

What makes finance different in a venture capital context

Comparability across the portfolio

As long as every portfolio company uses its own definitions, portfolio figures cannot be aggregated. Consistent definitions for revenue, recurring revenue, burn and runway, plus a shared reporting format, are the precondition for a fund being able to compare its holdings at all.

Runway is a management metric

The question of how many months the funds will last must be answerable at any time – in the base case and in a conservative scenario. That includes how much growth each euro deployed generates. Both figures determine the timing of the next round and the negotiating position from which it is run.

Preparing for the next round

A cap table, dilution calculation, an integrated financial model and a data room that stands up to scrutiny are not created in four weeks. Portfolio companies that maintain these documents continuously shorten their funding processes considerably – and avoid valuation discounts that arise purely from a lack of verifiable evidence.

Typical starting points in the portfolio

Every company reports differently

Different definitions for the same terms make aggregation impossible. A binding reporting template solves this with little effort.

The runway is an estimate, not a calculation

Without a link between headcount planning, contract position and liquidity, you get a number that shifts every month. An integrated model makes it reliable.

The data room is only built under time pressure

When documents are only pulled together once the process is running, it costs weeks and negotiating position. Ongoing maintenance is far cheaper than reconstruction.
