The Bottleneck Index 2026: What Slow Follow-Up Costs

The JSU Bottleneck Index prices a single question, per industry: what does it cost you, per year, to be slow and unfocused at first contact? The method is deliberately simple, so you can run it on your own numbers.

The formula

Annual bottleneck equals your average deal value, times the winnable deals you lose per quarter to speed and aim, times four. That is it. No black box. The hard part is being honest about the second number.

Two failures, compounded

The leak is the product of two distinct failures. Speed: inquiries cooling past the window before a credible response. Aim: pages and messages that read every buyer identically. A team can be fast and generic, or precise and slow, and still leak. You need both fixed, which is why the engine is built per industry, because the clock and the criteria are set per industry.

Why the windows differ

Staffing cools in hours because reqs get filled by whoever answers the same day. Construction holds for days because bid cycles are long, but the list closes early, so the real window is shortlist formation, not response time. Same principle, different clock.

The bottleneck is rarely effort. It is speed and aim at the first touch.

What the numbers look like across industries

The leak scales with deal size and how fast the window closes, and the spread is wide. In SaaS, demo requests cool in about six hours, and at a $36,000 average annual contract value, four lost deals a quarter is $576,000 a year. In staffing, at a $28,000 average placement fee, four lost placements a quarter is $448,000 a year. In commercial HVAC, at a $38,000 average project with a four-hour window, three lost jobs a quarter is $456,000 a year. In logistics, at a $96,000 average contract losing three shippers a quarter, the leak runs over $1.1M a year. Bigger deals leak more per miss; faster windows simply leak more often.

• SaaS: $36,000 average ACV, a six-hour window, four lost a quarter, $576,000 a year.
• Staffing: $28,000 average placement, a four-hour window, four lost a quarter, $448,000 a year.
• Commercial HVAC: $38,000 average project, a four-hour window, three lost a quarter, $456,000 a year.

Why the leak is invisible on the books

The reason most founders underprice the bottleneck is that the lost deals never appear as losses. A deal you answered too late, or answered generically, usually went to a competitor before it ever entered your pipeline as an opportunity. There is no line item for the shipper who quoted with someone faster, or the merchant whose retention desk called before you did. The leak hides in the deals you never knew you were in, which is exactly why pricing it deliberately, rather than feeling it, is the point of the Index.

What the Index is really measuring

The Index is not measuring effort, headcount, or talent. It is measuring two things at the first touch: how fast a credible response lands, and how well aimed it is. A team can work hard, hire well, and still leak six figures a year because its first response is slow, generic, or absent on the night the signal fires. That reframes the problem from a people problem into a system problem, and a system problem is one you can fix once and run.

Why the leak compounds instead of staying flat

A bottleneck is not a fixed annual cost, it grows, because the deals you lose to speed and aim do not just disappear, they go to a competitor who now has the account, the relationship, and the next renewal. Each quarter the leak repeats, and each lost buyer becomes a competitor's compounding base. In recurring-revenue markets this is brutal: a single lost contract is not one missed sale but every renewal that would have followed. That is why a six-figure annual figure understates the real damage, because it prices this year's miss without pricing the multi-year relationships those misses handed to someone faster.

What closing the bottleneck actually requires

Closing the leak means fixing both failures at the first touch, not one. Speed without aim simply loses faster; aim without speed misses the window entirely. That requires answering inside the industry's window, every time including nights and weekends, with a message aimed at the specific buyer rather than the average one. A human team can do this brilliantly for a handful of accounts but cannot hold it across a whole territory around the clock. That is the gap an engine is built to close: it answers fast, profiles the buyer, and hands a warm conversation to a person, so the window stops being the thing that costs you the work.

Run it on your real numbers

The published figures are representative. The value of the Index is the method, not the averages. Take your average deal, your honest quarterly loss to slow and generic follow-up, and price your own leak. Then decide whether that number is worth closing. The honesty is the hard part, because the quarterly loss is the figure nobody likes to write down, and it is precisely the figure the Index forces into the open. Run it once on your real numbers and the bottleneck stops being a vague feeling that you are leaving money on the table and becomes a specific number you can choose to close or keep paying every quarter.
