About Chuck McMahon

Most $2M-$20M B2B SaaS companies do not have a growth problem. They have an Expansion ARR problem that shows up as margin pressure.Revenue is increasing.Headcount is increasing.Customer complexity is increasing.Gross margin is not.NRR hovers just above acceptable.Cost to serve climbs quietly.Expansion depends on individual effort rather than system design.This is not a motivation issue.It is a revenue architecture issue.I work as a Fractional Chief Customer Officer for B2B SaaS companies between $2M and $20M ARR.The focus is narrow:• Increase Expansion ARR in the existing customer base• Protect and improve gross margin as delivery scales• Reduce cost to serve through structural clarity• Build disciplined visibility into Net Revenue RetentionThis is typically a structured 90-day reset.During that period, we examine where revenue is leaking, where margin is being absorbed by complexity, and where incentives distort expansion behavior. Then the customer revenue structure is redesigned so expansion and margin reinforce each other rather than compete.I do not operate as a general operator or broad-growth advisor.The work sits at the intersection of customer success, revenue operations, delivery, and executive decision-making. The objective is simple and measurable.The goal is straightforward.Expansion becomes systematic rather than episodic.Gross margin remains visible and defensible as the customer base grows.Leadership has clear signal into NRR and cost to serve.The economics make sense.

   amplificx is a founder led advisory focused on increasing Expansion ARR and protecting gross margin in B2B SaaS companies between $2M and $20M ARR.The work centers on customer revenue architecture.As SaaS companies grow, customer count increases, service variation expands, and revenue complexity outpaces structure. Expansion becomes inconsistent. Cost to serve rises. Net Revenue Retention lacks clear visibility.These issues rarely appear as dramatic decline. They show up as margin compression, reactive customer success, and expansion that depends on individual effort rather than system design.I work directly with founders to diagnose where revenue is leaking, where margin is being absorbed by structural misalignment, and where incentives distort expansion behavior.The engagement is typically a focused 90-day reset.We clarify segmentation.Realign pricing and service levels.Model cost to serve by tier.Install NRR and cohort margin visibility at the executive level.The objective is straightforward.Expansion performance becomes systematic.Gross margin remains visible and defensible as the customer base grows.Leadership has clear signal into retention economics.AI is used selectively as a supporting tool where it improves signal clarity or reduces analytical friction. It is never the strategy. It supports decision quality inside a defined revenue model.amplificx is not a general operating advisory. The focus is narrow and economic.Expansion ARR.Gross margin.Customer revenue structure.
