A diagnostics startup spent 18 months and $4M selling a molecular test to hospital labs. Their evaluation pipelinepipelineAll active sales opportunities across the stages of the sales process, together with their combined potential value and probability of closing.Voir la définition complète → looked healthy: 60 labs ran pilots. But only 6 converted to paid contracts. Leadership blamed the sales team. The real problem was visible in a single benchmark comparison: their evaluation-to-purchase rate was less than half the sector norm, and their payback stretched past the point where the business could survive. The was not slow. It was leaking.
This lesson shows you how to use realistic biotech and medtech marketing benchmarks to find exactly where your commercial engine underperforms peers, and what each leak signals.
In consumer SaaS, a bad conversion rateconversion rateThe percentage of visitors or prospects who complete a desired action (purchase, sign-up, contact form), calculated as conversions divided by total opportunities.Voir la définition complète → costs you a few dollars per lead. In biotech and medtech, a single enterprise sale (a hospital system, a pharma R&D account, a national reference lab) can be worth six or seven figures over its life, and the sales cycle can run 9 to 24 months.
That means:

Formula:
CAC Payback (months) = CAC / (Monthly recurring gross margin per customer)Worked example. A medtech company selling a subscription monitoring device to clinics:

Benchmark context (estimates, as of 2025 data). Public and private SaaS benchmark studies from firms like OpenView and Bessemer typically cite healthy B2B SaaS CACCACCustomer Acquisition Cost (CAC) is the total sales and marketing spend divided by the number of new customers gained in a period. It measures how efficiently you grow.Voir la définition complète → payback around 12 to 18 months. For capital-heavy medtech and diagnostics with long enterprise cycles, payback is commonly longer, often 18 to 30 months, and investors tolerate this because contracts are sticky. Treat these as directional ranges, not audited figures. See Bessemer's cloud benchmarks for the software baseline you should adjust upward for medtech.
So our 17.1 months looks strong for medtech. If it were 40 months, that signals a leak: either CACCACCustomer Acquisition Cost (CAC) is the total sales and marketing spend divided by the number of new customers gained in a period.

In this sector, prospects rarely buy on a demo. They run pilots, evaluations, or in the case of diagnostics, validation studies (a lab confirms a test performs as claimed on their own samples before buying). This is the equivalent of a mid-funnelfunnelThe customer journey from awareness to purchase, typically Awareness, Interest, Consideration, Decision, Action, with prospects narrowing at each stage.Voir la définition complète → trial-to-paid conversion, but it is slow and consumes real reagents, staff time, and instrument access.
Formula:
Eval-to-purchase rate = Paid contracts won / Evaluations startedBack to the opening story: 6 contracts from 60 pilots is a 10% rate.
Benchmark context (estimates). There is no single audited figure here, so anchor on structure rather than a magic number. For high-consideration B2B medtech and lab products, credible internal benchmarks from commercial teams often land in the 25% to 40% range for well-qualified evaluations. A rate near 10% almost always means one of two things:
The diagnostics startup had both problems. They ran pilots with any lab that raised a hand, and their pilot did not measure the metric hospital procurement actually cared about: turnaround time reduction.
Once you win a customer, do they stay and grow? Net Revenue Retention (NRR) measures revenue from existing customers this year versus last year, including expansion and losses.
Formula:
NRR = (Starting revenue + expansion - contraction - churn) / Starting revenueWorked example. A cohort worth $1,000,000 last year. This year the same accounts generated $1,050,000 after some expanded and some canceled.

Medtech and diagnostics with embedded instruments and workflow lock-in can achieve very high retention (annual logo churnlogo churnChurn rate is the percentage of customers or revenue lost over a period.

Diagnose in order, because leaks upstream masquerade as problems downstream.
Step 1: Check evaluation-to-purchase first. If it is far below range, do not add more leads. You will just start more pilots that fail. Fix qualification and evaluation design.
Step 2: Check CAC payback. If eval-to-purchase is healthy but payback is long, your acquisition is inefficient. Common medtech causes: expensive field sales deployed against low-value accounts, or long free-pilot periods where you fund the customer's evaluation with no revenue.
Step 3: Check NRR and churn. If acquisition looks fine but the business struggles, you are losing customers you paid dearly to win. In medtech this often traces to poor onboarding (the device sits unused) or missed clinical outcomes.
A European CDMO (Contract Development and Manufacturing Organization, a firm that makes drugs for other companies) sees:
The read: acquisition works, but they are overspending to win accounts that then shrink or leave. The fix is not marketing volume. It is retention and expansion: closer account management, and building switching costs through integrated quality systems.

Beware regulatory-driven cycles.
