What a 98% Renewal Rate Tells an Investor About a Company’s True Moat

A 98% renewal rate is not just a customer success statistic. It is one of the cleanest signals in a diligence file that a company may have built something far more durable than a good sales motion. In recurring-revenue businesses, retention is where narrative meets reality. Growth can be bought for a while. Brand can create noise. Product demos can impress. But customers only renew at very high rates when the company has become hard to remove from the workflow, hard to replace economically, or hard to live without operationally. 

That is why renewal data deserves more respect in venture and private equity diligence. McKinsey’s recent work on private equity exits makes the point directly: the most credible value-creation plans focus on a small set of KPIs that prospective buyers can validate in diligence, and customer retention is one of the clearest among them. At Azafran Capital Partners, we think about this through the lens of applied deep tech and operating quality. In MedTech, IoT, enterprise B2B, and recurring services models, retention is often the most honest signal of whether the company has built a real moat or just a temporary revenue engine. A 98% renewal rate does not answer every diligence question, but it usually tells you you are looking at something worth taking seriously.

Retention is the metric customers cannot fake for you 

Many operating metrics can be flattered. Pipeline can be inflated. Bookings can be pulled forward. Margin can improve briefly under cost pressure. Even growth can mask fragility if it depends on aggressive spending or discounting. Renewal rate is different. It reflects a decision made by the customer after they have lived with the product or service, experienced the implementation, tested the value, and weighed alternatives. 

That is why retention carries disproportionate informational value. It compresses multiple truths into one number: product relevance, delivery quality, switching friction, pricing tolerance, customer satisfaction, and operational consistency. In software and recurring services, that is powerful because the market already recognizes retention as a core benchmark. The KeyBanc and Sapphire Ventures private SaaS survey reported gross retention holding around 90% in 2024, with modest improvement expected, and net retention around 101%. In that context, a 98% renewal or gross retention profile is not just “good.” It is meaningfully above the norm.

For an investor, that kind of number immediately changes the diligence posture. The question becomes less “Do customers like this?” and more “What structural advantage is producing this?” 

A 98% renewal rate usually signals one of three real moats 

High renewal does not happen by accident. In my experience, it usually points to one or more of three underlying forms of moat. The first is workflow embedding. The product or service sits deep enough inside the customer’s operations that removal creates disruption. This is common in enterprise B2B, infrastructure software, managed services, and operationally critical platforms. The offering becomes part of how work gets done, not just a layer sitting on top. 

The second is economic clarity. The customer can see the return. Maybe the company saves labor, reduces downtime, improves compliance, speeds deployment, or lowers risk. Whatever the mechanism, the value is concrete enough that renewal feels rational rather than discretionary. The third is trust-based stickiness. This is especially important in services, cybersecurity, regulated sectors, and applied deep tech. Customers stay because the provider has earned credibility in environments where failure carries a cost. EY’s recent work on top-performing companies highlights the role of recurring revenue, stable customer relationships, and embedded services in creating predictable cash flows, lower volatility, pricing leverage, and stronger retention. When a company posts 98% renewal, it often means one of those moats is already in place. Often it means more than one. 

In diligence, retention often matters more than the growth story 

This is where investors sometimes get distracted. A fast growth story is exciting. A high renewal story is believable. The best companies have both, but if I had to choose which metric tells me more about underlying business quality, I would usually take retention. 

Why? Because retention is what survives after the sale. McKinsey’s work on exits is useful here. Buyers are looking for operational progress that translates into enterprise value and can be validated in diligence. Customer retention is explicitly one of those metrics because it speaks directly to revenue durability and future cash-flow confidence.

That matters in both venture and PE contexts. In venture, strong retention often tells you the company has found real product-market fit rather than curiosity-driven adoption. In private equity, it signals resilience, supports underwriting confidence, and often strengthens the quality of earnings story at exit. It also improves how other metrics should be interpreted. Growth with weak retention can be a leaky bucket. Growth with 98% renewal usually means new revenue is landing on top of a solid base. 

The number alone is not enough; the composition matters 

A smart deal team should never stop at the headline figure. 

A 98% renewal rate is powerful, but the follow-up questions matter. Is that logo retention, gross revenue retention, or a contract-based renewal metric? Is it concentrated in a handful of large accounts? Is it propped up by multi-year terms that delay churn visibility? Is the company discounting heavily at renewal? Are customers renewing because they are delighted, or because switching is painful and the alternatives are weak? 

These questions do not weaken the value of the metric. They sharpen it. 

The best diligence work decomposes the number by cohort, segment, product line, contract size, implementation path, and tenure. In AI and emerging software categories, Bessemer has noted that traditional SaaS retention frameworks can miss the real story unless retention is measured by use case and workflow dependence. That is a useful reminder for investors: renewal is most informative when tied to how mission-critical the solution actually is.

So the right posture is not to worship the number. It is to use it as a gateway to the real moat analysis. 

In services and applied deep tech, retention is often a proxy for execution quality 

This matters even more in the kinds of businesses we care about at Azafran. 

In applied deep tech, MedTech, IoT, enterprise B2B, and recurring service models, customers do not stay simply because the technology sounds advanced. They stay because the company consistently delivers. That means implementation works. Service quality holds up. Problems get resolved. The product integrates into real workflows. The organization earns trust over time. 

That is why I view retention as not just a product metric, but an operating metric. 

A 98% renewal rate usually tells you the company has figured out something beyond sales. It has likely built an execution system customers trust. And in many categories, that system is the moat. Not just the code, not just the feature set, not just the brand. 

This is one reason retention should matter so much in an Azafran-style diligence framework. We are interested in long-term value accretion through operational excellence, not financial engineering. A company that renews at 98% is often telling you it already understands how to create repeatable value after the initial contract is signed. 

What I would infer from 98% renewal before writing a check 

I would not assume perfection. But I would assume the company deserves deeper attention. A 98% renewal rate suggests the business may have durable customer value, real switching friction, stronger-than-average revenue quality, and a more resilient path to compounding. It often indicates a cleaner base for expansion, better predictability in planning, and a stronger story at exit because buyers trust revenue that customers repeatedly choose to keep. Public and private market research alike continues to reinforce that recurring relationships, retention, and revenue durability are central to valuation quality and operational credibility. In other words, retention data is often the most honest signal in the file because it reflects what the customer does when the pitch is over. That is why a 98% renewal rate gets my attention. Not because it sounds impressive on a slide, but because it usually means the company has built something real. And in a market full of narrative, “real” is still the best moat an investor can find.
