Plain answers about how Constantine Consulting works — what a fractional Chief AI Officer is, what AI consulting costs for a small business, who does the work, and how to get started.
Constantine Consulting is a boutique AI consulting firm in Greer, South Carolina that helps small and mid-sized businesses implement AI, build sales and growth systems, and develop custom software. A small senior team — led by former public-company CEO John Constantine — scopes and delivers every engagement, with no junior hand-offs.
We work across four areas: AI consulting and implementation, sales and growth strategy, executive coaching, and custom AI application development.
A fractional Chief AI Officer is a senior AI leader who guides your AI strategy and implementation part-time, for a fraction of a full-time executive's cost. You need one if you know AI matters but aren't ready to hire a full-time AI executive. Constantine Consulting serves as an outsourced, fractional Chief AI Officer for SMBs.
In this market, fractional CAIO engagements commonly run $2,000–$8,000 per month versus $400,000+ for a full-time hire — roughly 70–80% of the value at 15–30% of the cost.
It depends on scope. Across the market, SMB AI consulting ranges from about $2,000 for a readiness assessment to $50,000+ for full implementation; fractional Chief AI Officer retainers commonly run $2,000–$8,000 per month. Constantine Consulting sizes each engagement to your goals on the first call — from a one-day Summit Session to an ongoing Rope Team Retainer.
There are no packaged programs or junior hand-offs; you pay for senior people doing the actual work.
Yes. Constantine Consulting is built for small and mid-sized businesses, growth-stage founders, and SME/mid-market CEOs who need senior AI and growth leadership without the cost of a full-time C-suite hire. The firm specializes in practical, deployed AI that delivers measurable results — not enterprise theory.
It's an especially strong fit for businesses with roughly $1M+ in revenue that feel pressure to adopt AI but lack dedicated AI leadership.
Constantine Consulting builds production AI systems: multi-agent architectures, agentic workflow design, full Claude (Anthropic) ecosystem integration, and automation pipelines using tools like n8n. The team has built and deployed 60+ AI and technology solutions and four full AI SaaS platforms from the ground up.
Engagements range from AI readiness assessments to fully built, customer-facing AI applications in React/TypeScript with LLM integration.
A boutique firm gives you senior specialists doing the work directly, faster and at 40–60% less cost than Big 4 engagements — with no junior hand-offs. At Constantine Consulting, the people who scope your work are the people who do it, led by a founder who has actually run a public company, not just advised one.
You get operator experience and implementation continuity instead of a slide deck and a rotating team.
The same senior team, every time. Three specialists — an operational expert, a technical expert, and an integrator (business strategist and project manager in one) — assembled by founder John Constantine, who is in every engagement. There are no junior pass-offs; the people who scope the work are the people who deliver it.
John Constantine is the founder of Constantine Consulting and a former publicly traded (TSX-V) company CEO. He led IPOs, M&A, and the post-COVID turnaround of ARCpoint Labs from 120 to over 350 locations. He brings 25+ years of sales and growth leadership and has built 60+ AI and technology solutions.
He works directly in every engagement as the firm's senior operator and AI architect.
Three models. A Summit Session is a one-day strategic intensive that ends with a concrete action plan. A Rope Team Retainer is an ongoing monthly advisory relationship where the team becomes part of your leadership. A Project Engagement is a defined-scope build — a sales system, an AI implementation, or a custom application — with clear deliverables and timeline.
IP co-ownership is available on custom builds.
Constantine Consulting works across industries, with particular depth in franchise and multi-unit operations, professional services, healthcare/diagnostics, and SMBs scaling national sales. The common thread is operators who want measurable AI and growth outcomes, not theory. The team's experience spans labs (ARCpoint, 350+ locations), SaaS, and national sales networks.
Constantine Consulting is based in Greer, South Carolina (the Upstate / Greenville–Spartanburg region) and works with clients across North America. Most engagements run virtually, with quarterly time in person; on-site work is available continent-wide. The office address is 503 Sugar Mill Road, Greer, SC 29650.
Yes. Constantine Consulting builds full-stack, AI-powered applications — SaaS platforms, customer-facing apps, dashboards, and CRM/workflow integrations — using the Anthropic API and LLMs in production React/TypeScript builds. Platforms that historically cost hundreds of thousands are delivered faster and for far less, with an optional IP co-ownership model.
