A benchmark study by Artemis GTM across 253,817 inbound leads at 1,247 companies exposes an uncomfortable truth: the average response time to a new lead is 42 hours. Not 42 minutes. 42 hours. Only 7% of businesses hit the 5-minute benchmark that demonstrably gives the highest odds of conversion.
Every lead that waits more than a few minutes for a reply is already checking out a competitor. That is not a guess. It is measurable, and the numbers got sharper this year.
The numbers that change how you look at response time
Research from Velocify across 3.5 million leads shows that calling within 1 minute of an enquiry increases conversion odds by 391% compared to calling after just 2 minutes. Two minutes, not two hours. InsideSales found that 35 to 50% of all sales go to whoever responds first, rising to 78% in competitive markets.
Meanwhile customer expectations keep climbing: 64% of consumers now expect a real-time response, up from 58% in 2023. The bar was already high. It is still rising.
Why this is a blind spot for digitally advanced businesses
This is where it gets uncomfortable for small businesses that consider themselves digitally ahead. Recent figures show Belgian businesses rank among Europe's top 5 for AI adoption: 34.5% use at least one AI technology (2025), and Statbel reports 1 in 4 Belgian SMEs already use AI in daily operations. That is not a small detail. It means most business owners already own the technology needed to respond within minutes.
The problem is rarely a lack of tools. It is that none of those tools have been pointed at the first response. A business automates invoicing, bookkeeping, sometimes even marketing, but the first contact moment with a new lead still depends on whoever happens to open their inbox.
Why every hour matters
The MIT/InsideSales.com study shows that qualification odds drop sharply within the first hour without a contact attempt. It is not a gradual decline. Every hour of delay pushes a deal closer to "never heard back."
Run the numbers: if you receive 20 leads a month and your average deal is worth €3,000, the difference between 25% and 35% conversion is 3 extra deals a month. €9,000. Over a year, more than €100,000, purely from responding faster to leads you already have.
What actually works
The businesses that beat these numbers are not working harder. They automate the first response. A speed-to-lead system or AI agent sends a personal-sounding reply within 60 seconds, proposes time slots, and keeps the lead warm until a human takes over the conversation. That is the literal difference between 42 hours and 1 minute, without hiring anyone new.

Frequently asked questions
What is the ideal response time for a new lead?
Research from Velocify shows calling within 1 minute increases conversion odds by 391% compared to waiting 2 minutes. Responding within the first 5 minutes gives the highest odds of conversion: MIT/InsideSales.com found leads are 21x more likely to qualify and 100x more likely to be contacted, compared to waiting 30 minutes.
How many businesses actually respond fast enough?
Globally, only 7% of B2B companies hit the 5-minute benchmark, with an average response time of 42 hours across 253,817 studied leads. National figures vary, but given how widely SMEs already use AI tools, the technology to close this gap is already in most businesses' hands.
Can I automate this without building a full call centre?
Yes. An automated follow-up system or AI agent responds to every enquiry within seconds, proposes time slots, and keeps the lead warm until a human takes over. It requires no extra hires, just a system set up once.
What does it cost to automate my response time?
A simple automated follow-up system starts around €600 one-time. Most businesses earn that back within the first month through extra converted leads that would otherwise have been lost.
Conclusion
The data is unambiguous: response time is not a detail in your sales process, it is the sales process. 42 hours on average, against a window of a few minutes where most deals are decided. The question is not whether you can automate this. Most small businesses already own the tools. The question is whether you have pointed them at the right problem yet.
