About Ignition Consultants
Ignition Consultants is a strategic fractional CFO firm headquartered in Greater Boston, serving owner-operators, family businesses, professional services firms, and growth-stage companies across the region and the broader Northeast.
Boston business owners looking for the best fractional CFO firm for their stage typically arrive at one of three doorsteps: a top-quartile finance function for ongoing operations, a team that has been in the room for serious capital events, or senior judgment for moments when the margin for error is zero. We do all three, whether the engagement is structured as an embedded fractional CFO, an outsourced CFO function, or interim CFO coverage during a transition.
Our founder, Craig Gainsboro, spent 15 years as the U.S. CFO of PricewaterhouseCoopers' Tax and Advisory Lines of Service before building Ignition into a 15+ person firm serving 250+ clients. Our team has been in the room for over $3 billion in capital raised, credit facilities arranged, and transactions supported across Boston-area companies and growth businesses nationally.
What makes us structurally different is the team itself. Most fractional CFO firms send you one strategic person who ends up doing junior work because there is nobody else to do it. We built a tiered team so the senior CFO is in the boardroom (or the owner advisory meeting, or the lender call) when the moment requires senior judgment, while the rest of the team handles the recurring close, modeling, and reporting work.
That is Big Four sophistication with startup agility. It is why Boston founders, owners, and CEOs hire us when it matters most.
What Boston Companies Call Us For
Most of the founders, owners, and CEOs we work with arrive at one of a few specific moments. The category names (fractional CFO, outsourced CFO, interim CFO, part-time CFO) describe what we do. The moments below describe why people actually pick up the phone.
You have been doing the strategic finance work yourself since day one because you had to be. Your bookkeeper or controller is keeping up with the past but cannot tell you about the future. You are making hiring, pricing, and capital decisions on instinct because the numbers do not exist in a form you can use. You need a function, not another individual.
The books are accurate enough. The monthly close happens. But there is no financial model, no rolling cash forecast, no real KPI reporting, and nobody senior enough to sit across from your bank, your auditor, or your board and answer the hard questions. You need strategic finance on top of the operating finance you already have.
Bank covenant reporting. Audit prep. A line of credit renewal that requires a real forecast. A refinancing that requires three years of clean financials. The current setup cannot produce what is being asked for, and the deadline is real.
You have built the business yourself, often over many years. Now you are facing a transition that will put the financial infrastructure under serious scrutiny: a sale, a generational handoff, an employee transition, or another major moment that brings sophisticated outside eyes onto your numbers. The setup that got you here will not survive the diligence the new situation requires, and the gap needs to close before that moment arrives.
You are buying a competitor or a complementary business. You need senior finance judgment for the diligence process, the deal structure review, and the post-close integration of accounting systems and reporting cadences.
Your CFO or controller left under difficult circumstances. You discovered something in the books. A covenant is at risk. You need senior judgment in the room within days, not weeks.
Industries We Serve in Boston
Tailored finance function for the industries that drive the Greater Boston economy:
Construction and Real Estate
Boston's construction and real estate ecosystem includes some of our deepest client relationships. Multi-entity structures, complex cash management, project-based revenue recognition, bonding and surety relationships, and bank relationship management all require senior finance judgment. We support general contractors, real estate developers, property management firms, and specialty trade businesses across the region.
Professional Services and Multi-Site Service Operators
Law firms, consulting firms, accounting practices, marketing agencies, dental and orthodontic groups, veterinary practices, and other multi-location service operators. Partner economics, cohort analytics, multi-site consolidation, and the financial reporting structure these businesses need as they scale or prepare for a transition. Particularly relevant for services firms preparing for sale, succession, or generational handoff.
Manufacturing, Distribution, and Logistics
Greater Boston manufacturers, specialty distributors, and logistics operators with inventory complexity, working capital intensity, and multi-location operations. We support cost accounting, gross margin analysis, working capital management, and lender reporting for the operating businesses that anchor the regional economy.
Family Businesses and Owner-Operated Companies
Multi-generational and owner-operated businesses across sectors. Translation from owner-operated bookkeeping to audit-grade or successor-ready reporting, often without disrupting a long-standing relationship with the CPA who got the company here. Particularly relevant for family business transitions, succession planning, and the financial maturation that comes with generational handoff or sale.
Technology, SaaS, and AI-Native Companies
Boston's technology ecosystem includes operating businesses across SaaS, AI-native, hardware, and enterprise software. We embed as the finance function for technology companies, building the model, organizing reporting, and supporting capital events, audits, and lender relationships.
Biotech, Life Sciences, and Healthtech
Cambridge and the Greater Boston biotech corridor produce companies with longer revenue runways, higher capital intensity, and complex diligence patterns. We support biotech and life sciences finance work with industry-specific modeling for milestone-based funding, grant accounting, and strategic partnership economics.
Why Work With a Boston-Based Firm
Boston operates differently from the way a national remote-first fractional CFO firm assumes business gets done. Lender relationships matter more here, and the lenders themselves cluster locally. Audit firms, transaction counsel, and regional law firms have deep Boston-area roots. Boards (where they exist) tend to be more involved, and owner-advisory relationships are often face-to-face.
Generic national fractional CFO firms do not have these relationships. We do. Our team has been the embedded fractional CFO for Boston-area companies for over a decade, with deep familiarity across Boston-area banks, lenders, audit firms, and transaction counsel.
When Boston business owners evaluate the top fractional CFO firms in their market, whether they are mid-market operators, growth-stage companies, or owner-operated firms, they consistently look for three things: ecosystem familiarity, in-person availability, and a team-not-solo structure. We are built around all three.
Face-to-Face Meetings Where They Matter
Unlike national fractional CFO firms that show up via Zoom, we attend your Boston-area board meetings, owner advisory sessions, lender presentations, and audit kickoffs in person. The work is fundamentally different in person, and the people on the other side of the table notice.
Boston Ecosystem Density
We know how Boston-area lenders structure credit facilities, term loans, lines of credit, and asset-based lending. We know which audit firms work well with which company stages and industries. We know how the major Boston-area transaction counsel approaches sell-side and buy-side diligence.
Local Lender and Service Provider Relationships
Standing relationships with the major Boston-area banks, regional lenders, audit firms, transaction counsel, and 409A specialists. The day you need any of them, you do not make a cold call.
Faster Response, In-Person Support
Local presence means we can respond to a crisis in hours, not days. When your refinancing is closing, your audit fieldwork is starting, or your board meeting is tomorrow, geographic proximity matters.

Embedded Fractional CFO Work Across Greater Boston
Remote-only fractional CFO arrangements have their limits, especially for companies in active capital events, audit cycles, or operating under a tight board or owner advisory structure. We provide embedded, in-person finance leadership across the Greater Boston area.
We work side-by-side with your team to:
- Embed in your operations. Senior CFO presence in your office for regular work sessions, not just for board meetings.
- Run board and advisory meetings live. Senior partner attends board meetings or owner advisory sessions in person, presents financials, and handles questions directly.
- Coordinate with your existing team. We work alongside your CPA, your bookkeeper, your accounting firm, not against them.
- Manage your lender and audit relationships. Direct relationship with your existing financial service providers, not requiring you to introduce us each time.
Service Areas
Our Boston Fractional CFO Process
We do not guess. We follow a structured framework refined across hundreds of engagements, adapted to each company's specific stage, industry, and trigger moment.
Diagnostic Call
Thirty-minute call with Craig or another senior partner. We identify what is broken (or about to break), what success looks like at 30, 60, and 90 days, and whether we are a fit. No questionnaire required first.
Scope Document
Within 48 hours of the diagnostic, we send a focused scope document: named team, cadence, deliverables, price. Not a marketing-as-proposal artifact, just the working scope.
Embedded Engagement
Engagement starts within two weeks. Senior CFO embeds first to absorb context. The rest of the team layers in over the following weeks. By week 6, your finance function runs on our infrastructure.
Board-Ready or Lender-Ready in 60 to 90 Days
The first board meeting, owner advisory session, or lender presentation after engagement start is materially different. The variance commentary makes sense. The KPI dashboard is consistent. The cash position is current. The forecast holds up under questions. The people across the table notice.
Fractional CFO Services We Provide in the Greater Boston Area
Our service offerings cover the full range of senior finance work for Boston-area companies, whether you need an embedded fractional CFO, an outsourced CFO function, an interim CFO during a transition, or a part-time CFO arrangement. The terminology varies. The work is the same.
Embedded Fractional CFO Function
Continuous monthly engagement covering ongoing senior finance work. Senior CFO presence in board meetings or owner advisory sessions, monthly close oversight, KPI reporting, on-call strategic capacity for hiring, pricing, and capital decisions. The most common engagement model for Boston-area companies that have outgrown a founder-or-owner-as-CFO setup.
Books Cleanup and Controllership
Full historical cleanup, chart of accounts rebuild for industry-appropriate reporting standards, monthly close discipline, and reconciliation procedures across all accounts. Specifically designed for companies whose bookkeeper or controller setup has plateaued and needs senior structure layered on top.
Strategic Financial Modeling and Cash Forecasting
Three-statement financial model build, 13-week rolling cash forecast, scenario modeling for hiring, pricing, capital, and growth decisions. The model is built once, maintained monthly, and stays with the company when the engagement ends.
Bank, Lender, and Audit Relationship Management
Senior CFO presence in lender meetings, covenant reporting, line of credit renewals, refinancings, audit kickoffs, and audit fieldwork support. Direct relationships with the major Boston-area banks and regional lenders mean introductions when you need them.
Owner-Operated to Audit-Grade and Sale-Ready
You have built the business yourself. Your CPA does taxes, your bookkeeper closes the books, and you sign every check. That setup worked for years. It will not survive a serious audit, a sophisticated buyer's diligence, a strategic sale, or a bank that wants three years of clean financials before extending credit. We translate owner-operated bookkeeping into the kind of reporting structure that holds up under scrutiny, without disrupting your relationship with the CPA who got you here. Particularly relevant for owners preparing for sale, succession, audit, refinancing, or a serious bank or surety relationship.
M&A and Sale Preparation
Sell-side preparation, buy-side diligence support, deal structure review, and post-close integration. Our team has experience from many successful (and difficult) transactions. We help structure deals, manage diligence processes, and integrate financial systems post-close. Particularly relevant for Boston-area companies receiving acquisition interest or planning a strategic acquisition.
Capital Strategy: Bank Debt and Lender Relationships
Strategic capital work for companies past the early stage. Senior debt and credit facility structuring, asset-based lending review, line of credit renewals, refinancing strategy, and lender relationship management. Includes lender introductions from our standing Boston-area relationships.
Interim CFO Coverage
Coverage during a CFO or VP Finance transition, M&A integration, restructuring, or other moments when senior finance leadership is required immediately and continuity matters. We are usually in seat within two weeks of signed scope.

Frequently Asked Questions: Boston-Area Fractional CFO Services
The terminology varies across firms and across industries. In practice, a fractional CFO is a senior finance leader engaged for a portion of full-time hours on an ongoing basis. An outsourced CFO function is the same work delivered by a firm rather than an individual, often with a tiered team behind the senior partner. An interim CFO is engaged for a defined transition period, typically during a search for a permanent CFO, after a departure, or during a specific event. A part-time CFO is the colloquial version of fractional. Ignition delivers all four, structured to match the moment.
A controller manages the recurring close, reconciliations, and reporting accuracy. A CPA firm handles taxes, attestation, and (sometimes) audit work. A fractional CFO does strategic finance: model building, cash forecasting, board and lender reporting, capital strategy, M&A and capital event support, and on-call judgment for hiring, pricing, and capital decisions. Most growing companies eventually need all three. We work alongside your existing CPA and controller, not against them.
