Outcomes you can ask about on a reference call

Every engagement below is real, local, and recent. Names and full case studies are shared in conversation with our clients' blessing. That is how we would treat your story too.

Cambridge A landmark institution and one of its best-known construction firms
Newton A medical-technology company through SAFEs and growth financing
Boston Venture-backed companies from the Seaport to Back Bay
Everett A family construction firm rebuilt, not patched

Stuck in Quality of Earnings for months, then through it.

A Greater Boston healthcare-technology company sat stalled in QofE while an acquisition waited. We rebuilt what the acquirer's accountants needed and got the deal moving.

A $7–10M raise, investor-ready in one quarter.

A Cambridge AI company preparing a $7–10M raise needed a data room and model that could survive institutional diligence.

PE-grade reporting for a PE-owned company.

A Boston cybersecurity company in a national private-equity portfolio needed board-grade finance its team could not produce alone.

An $86M succession, handed off clean.

A Boston company preparing generational succession needed acquisition-ready metrics and a finance function the successor could actually run.

From flying blind to a real finance function.

An Everett construction company's growth outran its bookkeeping. We built the budgets, reporting, and controls a scaling operator needs.

Industry context

Open the language closest to your business.

Operating companies Growth-stage and middle-market, the core of the practice

Operators, including family businesses in generational transition. We take owner-operated books to audit-grade and sale-ready, succession included, and build the monthly discipline a lender or successor can rely on.

Venture-backed companies Equity and debt for venture-backed startups, first round to exit

SaaS, AI-native, hardware, and enterprise software: we build the model, keep the books raise-ready, and stand beside you through the round. Grant accounting and milestone models support the Cambridge biotech corridor.

Funds & GPs Fund-side work for Boston investors; emerging managers welcome

Management-company books kept clean and separate from fund books, fund-administration oversight, and LP reporting that survives scrutiny.

Family offices & trusts Multi-entity, multi-trust accounting brought current

Consolidated views, monthly closes that keep backlogs from returning, and modernized systems with history intact, coordinated directly with trust and estate attorneys and outside tax professionals.

Real estate, construction & manufacturing Among our deepest operator clusters

Project-based revenue recognition, multi-entity structures, bonding and surety relationships, cost accounting, gross margin analysis, working capital, and lender reporting.

Professional services Our largest active industry

Law firms, agencies, consultancies, and multi-site clinical groups: partner economics, realization and partner draws, multi-site consolidation, and preparation for succession or sale.

How the team works

A senior CFO leads. Specialists support. Technology accelerates the mechanics.

Senior CFOs remain accountable for every recommendation. AI helps the team organize source materials, test models, reconcile information, prepare analysis, and preserve operating context. A responsible finance professional reviews the work before it reaches the client or informs a consequential decision.

Judgment remains accountable.

A senior CFO owns the recommendation while technology supports source organization, model testing, reconciliation, and analysis preparation.

Collective intelligence, inherited on day one.

Every engagement sharpens the playbooks: what diligence asks, what lenders underwrite, and what boards believe. Your engagement never starts from scratch.

Speed you can feel.

Variance analysis in 30 minutes instead of two days. Monthly forecasts in about an hour. Fast enough to run the business by.

Honest judgment on the new stack.

Hands-on experience with emerging AI-native ERPs, and a straight answer about what is ready for your business and what is not.

How an engagement starts

A focused first 60–90 days

For many engagements, the first 60–90 days establish reliable reporting, a usable forecast, cash visibility, and the operating roadmap. The exact result depends on the quality of the existing books, systems, source material, and management availability.

Embedded fractional CFO function

A continuous monthly engagement: your senior CFO in board and advisory meetings, the monthly close, KPI reporting, and strategic capacity on call.

Books cleanup & controllership

Historical cleanup, chart-of-accounts rebuild, and a monthly close discipline that holds for companies whose bookkeeper or controller setup has plateaued.

Modeling & cash forecasting

A three-statement model and a 13-week rolling cash forecast, built once and maintained monthly. The model stays with the company when the engagement ends.

Bank, lender & audit relationships

Lender meetings, covenant reporting, line-of-credit renewals, refinancings, and audit support, presented the way a banker underwrites.

Owner-operated to audit-grade

We translate owner-operated bookkeeping into audit-grade, sale-ready reporting without disrupting your relationship with the CPA who got you here.

M&A & sale preparation

Sell-side preparation, buy-side diligence, deal structure, and post-close integration from a team with many successful and difficult transactions behind it.

Capital strategy & debt

Which facility, which lender, and what structure: settled before you sit across from the bank. Includes debt structuring, asset-based lending review, and refinancing strategy.

Senior coverage through CFO transitions, integrations, and restructurings. We are usually in seat within two weeks of signed scope.

Questions Boston companies ask

Fractional CFO questions, answered by situation

Filter questions
Boston & local Where are you located?

Our office is at 200 Boston Providence Highway, Suite 203, in Dedham, just off I-95 and Route 128.

Boston & local Do you work in person?

Yes. Most recurring work can be handled virtually, while senior team members join in person for planning, management, board, lender, investor, and transaction sessions where being in the room improves the result.

Boston & local Do you work with companies outside Boston?

Yes. Ignition serves companies across the United States while maintaining its headquarters and local practice in Greater Boston.

Working with us Who actually does the work?

A senior CFO leads each engagement and remains accountable. Finance professionals and specialists support the recurring work at the appropriate level, backed by the systems and experience of the broader Ignition team.

Working with us What happens in the first 90 days?

For many engagements, the first 60–90 days establish reliable reporting, a usable forecast, cash visibility, and an operating roadmap. The exact result depends on the quality of the existing books, systems, source material, and management availability.

Working with us What does it cost?

Pricing depends on company stage, complexity, and the work required. Ignition offers monthly retainers, fixed-scope projects, and hybrid engagements, with the proposed team, deliverables, cadence, and price documented before work begins.

Working with us What are the terms?

There is no annual lock-in. We provide a 90-day plan, and clients can cancel with 30 days notice.

Working with us Do you prepare taxes or sign audit opinions?

No. We do not prepare tax returns or provide audit, review, or compilation opinions. We work on the client side and coordinate with outside tax professionals and auditors.

Working with us Can you work with our current controller or bookkeeper?

Yes. We can oversee, support, and develop an existing controller or bookkeeper while the senior CFO leads forecasting, reporting, capital planning, and consequential decisions.

Financings When should we begin before a raise, refinancing, or exit?

Begin roughly 6–12 months before an equity raise, 3–6 months before a refinancing, and about 12 months before an exit when possible. Starting earlier preserves more time to repair reporting, models, records, and diligence materials.

Boston & local What local coordination can you provide?

We coordinate directly with Greater Boston management teams, boards, lenders, investors, audit firms, transaction counsel, and other local financial relationships when the engagement requires it.

Working with us How fast can an urgent engagement begin?

We are usually in seat within two weeks of a signed scope. The first call identifies the immediate risk, required team, and fastest responsible starting plan.
