Startup CFO Advisory
CFO-Level Financial Guidance
Built for Early-Stage Companies
Finance Infrastructure From Day One
We help early-stage companies build the financial foundation they need -- accounting systems, reporting processes, equity structures, and controls -- before investors and auditors start asking for them.
Fundraising and Investor Readiness
We prepare the financial models, data rooms, and due diligence packages that institutional investors expect -- and help management navigate the financial questions that arise during a capital raise.
Grow Into Your Finance Function
We design finance infrastructure that scales. What you need at seed stage is different from Series A, which is different from Series B. We build for where you are going, not just where you are.

CFO Advisory for Startups and Early-Stage Companies
What makes us different?
Early-stage companies face a specific set of financial challenges — building a finance function from scratch, navigating their first institutional capital raise, managing complex equity structures, and establishing accounting policies that will hold up under investor and auditor scrutiny. These are not problems a bookkeeper or part-time accountant can solve, but they do not yet justify the cost of a full-time CFO.
Corviniti provides CFO-level financial advisory to startups and early-stage companies that need senior financial guidance without the overhead of a full-time executive hire. We help founders and management teams build the financial infrastructure their business requires, prepare for institutional capital raises, and navigate the technical accounting questions that early-stage companies consistently encounter.
We work with companies from pre-revenue through Series B and beyond. Our advisors have worked with venture-backed startups across technology, SaaS, fintech, life sciences, and other sectors, and understand the specific financial and accounting demands of each stage.
We help with:
- Accounting Systems Selection and Setup: Help select and implement the right accounting platform for your stage — QuickBooks, NetSuite, or others — and establish a chart of accounts and reporting structure that will scale.
- Financial Model Development: Build the financial model that forms the foundation for fundraising — revenue projections, unit economics, burn rate, and cash runway analysis.
- Fundraising Financial Preparation: Prepare the investor materials, financial data room, and due diligence package for seed, Series A, and Series B capital raises.
- SAFE and Convertible Note Accounting: Advise on the accounting for SAFEs, convertible notes, and other early-stage financing instruments — one of the most common sources of technical accounting questions at this stage.
- Cap Table Management and Equity Accounting: Maintain the capitalization table, account for equity issuances, and prepare the stock-based compensation accounting under ASC 718.
- Revenue Recognition Policy: Establish the revenue recognition accounting policy under ASC 606 that reflects the business model and will satisfy auditor and investor scrutiny.
- Board Reporting and Investor Updates: Prepare the financial sections of board packages and investor updates — monthly reporting, KPI dashboards, and forward-looking financial commentary.
- Audit Preparation: Prepare for the first external audit — organizing financial records, resolving accounting questions, and building the workpapers auditors need.
- 409A Valuation Coordination: Coordinate the 409A valuation process and ensure the accounting implications of the valuation are properly reflected in the financial statements.
- Pre-Series A and Pre-IPO Readiness: Assess what the finance function needs to look like at the next stage and build a roadmap for getting there — so the company is ready when the opportunity arises.

Frequently Asked Questions
Most startups benefit from CFO-level advisory support once they have raised institutional capital or are actively preparing to do so. At that point, the financial reporting and modeling expectations from investors become more demanding, the equity structure starts to get complex, and technical accounting questions begin to arise that founders and bookkeepers are not equipped to handle. Engaging a CFO advisor at this stage is typically far more cost-effective than the alternatives — hiring full-time or scrambling to address investor concerns at the due diligence stage.
Startup CFO advisory is calibrated to the specific challenges of early-stage companies — building finance infrastructure from scratch, navigating early institutional capital raises, managing SAFE and convertible note accounting, establishing equity compensation programs, and preparing for a first external audit. The tactical priorities are different from those of a more mature company, and the advisor needs to understand those differences to be genuinely useful.
Series A investors expect a financial model that includes: a detailed revenue model with clear assumptions about the go-to-market strategy and unit economics, a cost build-up by function, a headcount plan, a cash flow projection with clear visibility into the burn rate and runway, and a set of operating metrics (CAC, LTV, churn, ARR growth) appropriate for the business model. The model should be internally consistent and the assumptions should be defensible under investor scrutiny. We help build or review financial models ahead of fundraising rounds.
Complex early-stage capital structures are one of the most common sources of accounting questions we address. SAFEs, convertible notes, and preferred equity each have specific accounting classification requirements under ASC 480 and ASC 815. We analyze each instrument, determine the correct accounting treatment, prepare the required journal entries, and document the conclusions in a format that will satisfy your external auditors when the time comes.
Being audit-ready means having organized, reconciled financial records, documented accounting policies, clean equity and cap table records, resolved technical accounting questions, and a general ledger that agrees to supporting documentation. Many early-stage companies have years of transactions that were recorded informally — when the first audit arrives, those need to be cleaned up and organized. We help companies prepare for the first audit by identifying and resolving issues in advance, so the audit process is efficient rather than disruptive.
We work alongside your existing team. In most startup CFO advisory engagements, the existing bookkeeper or staff accountant continues to handle day-to-day transaction recording, and we provide the CFO layer — reviewing the books, preparing board reporting, handling technical accounting questions, and managing investor and auditor relationships. We design the working arrangement around your team’s capabilities and the company’s needs.
Yes. We regularly work with foreign private issuers and companies with cross-border structures, including IFRS reporting, US GAAP reconciliations, and multi-entity consolidations for companies with domestic and international subsidiaries.
In most cases, we can begin within a few days of finalizing our agreement. Our onboarding process is straightforward — a brief discovery session, a clear statement of work, and secure access setup. We do not have lengthy intake procedures that delay the start of actual work.
