What is a Fractional CHRO?
A fractional CHRO is a senior human resources executive who serves as the chief human resources officer for a company on a part-time, ongoing basis — typically one to three days a week — instead of as a full-time employee. Companies hire fractional CHROs when they need executive-level people leadership — organizational design, talent strategy, leadership development, culture, compliance, executive team effectiveness, and people operations — but don't yet need or can't justify a full-time hire. The fractional CHRO model gives growing companies access to a partner-level operator who has built and scaled people functions before, for a fraction of the cost of a permanent CHRO.
Part-time, ongoing engagement: Typically 1-3 days per week, lasting months to years — not a one-off project.
C-level scope: Organizational design, talent strategy, leadership development, executive team effectiveness, compensation philosophy, and HR systems — not benefits administration or recruiting coordination.
Senior, experienced operator: A fractional CHRO has typically served as a permanent CHRO at one or more prior companies; the role is not entry-level.
Outside hire, embedded operator: The fractional CHRO is not an employee but operates inside the company — sits in leadership meetings, advises the CEO and board on people decisions, owns HR outcomes.
Builds the people function as the company scales: A good fractional CHRO designs the HR function so it works as the company grows — leveled roles, defined career paths, compensation bands, and clear processes for hiring, performance, and development.
Fractional CHRO vs Full-Time CHRO
Fractional CHRO
Engagement: 1-3 days/week, scaled to your needs
Total cost: 30-75% of a full-time COO, depending on usage
Time to value: weeks
Best for: 50 - 500 employee companies in scale-up, transition, or cultural reset
Full-Time CHRO
Engagement: full-time, permanent role
Total cost: $250K-$500K+ fully loaded (salary, bonus, benefits, payroll taxes, PTO)
Time to value: 6-9 months (recruit + onboard)
Best for: 500+ employee companies with complex mature people operations
Fractional CHRO vs HR Consultant vs PEO
These three options are often confused but serve very different purposes:
Model
Fractional CHRO
HR Consultant
PEO (Professional Employer Organization)
What it means
Embedded senior people leader on the company's leadership team. Strategic, operational, and accountable. Months to years.
Project-based advice and deliverables from outside the leadership team. Limited execution authority. Usually scoped to a specific problem.
Outsourced HR administration — payroll, benefits, compliance — not strategic people leadership. Companies often use a PEO and a fractional CHRO together.
When to hire a fractional CHRO
Companies typically bring in a fractional CHRO at one of these moments:
Scaling past 50 employees and the founder/CEO can no longer be the de facto head of people
Preparing for fast headcount growth and need leveled roles, compensation bands, and a hiring system in place before scaling
Cultural reset, post-layoff rebuild, or major leadership transition where the people function needs a senior voice
Replacing a departing CHRO with no immediate full-time hire identified, or bridging to a recruited permanent CHRO
Preparing for M&A, IPO, or PE recapitalization where the people function needs to be defensible in diligence· Scaling past 50 employees and the founder/CEO can no longer be the de facto head of people

How 2GO Advisory Group delivers fractional CHRO services
2GO Advisory Group provides fractional CHRO services through its CHROs2Go practice, part of the firm founded in 1986. Every engagement is led by a partner with 25+ years of C-level HR experience — no junior staff assigned to client work.
What separates 2GO from a solo fractional CHRO or a generalist firm is what happens when the engagement expands. If the CHRO work surfaces an adjacent need — executive recruiting for a permanent hire, a compensation system overhaul, a CFO or COO build-out, an integration project — the 2GO partner brings in and personally manages other senior partners from within the firm. The client maintains one relationship; 2GO handles the rest. This integrated model — fractional executive services, accounting, and recruiting under one accountable partner — is especially valuable for mid-market companies, professional services firms, and family-owned businesses that don't want to manage multiple vendors.
“Growing companies don't fail because of strategy. They fail because the people side hasn't caught up to where the business is going. The role of a fractional CHRO is to build the people function before the cracks show — leveled roles, real career paths, a hiring system that scales — so the company can grow without breaking the team that got it there.”
— Dr. Donna Hamlin, Practice Lead, CHROs2Go. Senior HR executive with 30+ years of C-level HR experience for private and public companies.
Frequently asked questions
-
Fractional CHRO engagements typically cost 30-7%5 of a full-time CHRO’s total compensation depending on scope, complexity, and the partner’s background. 2GO scopes each engagement to the company’s actual needs rather than selling fixed packages.
-
Most fractional CHRO engagements are 1-3 days per week, with the exact cadence flexing based on what’s happening in the business. During a hiring push, M&A integration, or organizational redesign, the time commitment may scale up temporarily.
-
Engagements range from a few months (for a specific transition or project) to several years (for companies that don’t plan to hire full-time). Many 2GO engagements run 12-24 months and end by transitioning into a recruited permanent CHRO.
-
Yes. Most 2GO fractional CHROs are hired specifically to lead an existing HR function — a director of people, an HR business partner, or an HR generalist — not to do the transactional work themselves. The fractional CHRO sets strategy and develops the team.
-
A recruiter helps you hire individual people. A fractional CHRO builds the system that determines who you should hire, how you assess them, where they fit in the organization, and how they grow once they’re in. 2GO offers both services in-house, so the fractional CHRO can integrate recruiting directly into the people strategy.
