Most mid-market businesses leak 30-50% of revenue in the gap between systems they think are working. The leaks are not in any single function. They are in the loops between functions: form-submit-to-call (inbound), call-to-CRM-to-calendar (qualification), brand-to-asset-to-channel (brand), ops-to-dashboard-to-decision (ops), content-to-traffic-to-pipeline (content). The Closed Loop Score finds the biggest leak in 5 minutes.
This post documents the framework. We use it as the diagnostic for every discovery call at luup. Operators who score themselves before the call save 30 minutes and ship 10x better follow-ups.
- 5 loops scored 0-5 each. Total out of 25.
- 21+ healthy; 16-20 leaking; under 16 hemorrhaging.
- The lowest-scoring loop is the fix priority - regardless of total.
- Scored in 5 minutes. Fixable in 7-21 days per loop.
- Run it now: /quiz walks you through it interactively.
1. Why score loops, not departments
Traditional business audits score departments: marketing, sales, ops, product. The pattern misses where mid-market revenue actually leaks - in the handoffs between departments. A great marketing team handing leads to a great sales team via a 17-minute callback gap loses just as much as a mediocre marketing team would.
This is why luup scores loops, not boxes. Harvard Business Review's response-time research showed conversion drops 10x between minute 1 and minute 5 of a lead's life. That gap lives in no department's KPI dashboard. It lives in the loop. Bain's revenue marketing stack research reaches the same conclusion via a different path.
2. The 5 loops
The 5 loops cover roughly 90% of where mid-market businesses leak revenue. The framework draws on patterns documented in Gartner's customer lifecycle marketing research, but operationalised for the mid-market revenue band where one founder still oversees every loop:
- Inbound Loop. The path from a stranger landing on your site to a real conversation. Owned by the voice agent + form layer.
- Qualification Loop. The path from real conversation to calendar-booked next step. Owned by the script, CRM, and calendar handoff.
- Brand Loop. The path from brand DNA to shipped assets across channels. Owned by the ad factory and brand system.
- Ops Loop. The path from weekly operations to founder dashboard and decisions. Owned by closed-loop automation.
- Content Loop. The path from one piece of content to compounded organic + repurposed reach. Owned by the SEO and content engine.
3. The scoring rubric
Each loop scores 0-5. Use the highest score that is honestly true for you.
| Score | Inbound | Qualification | Brand | Ops | Content |
|---|---|---|---|---|---|
| 5 | Under 90s to real conversation | Auto-routed with 2+ qualifiers captured | 8 brand rules + 6 primitives + 40 assets/mo | Closed-loop ops + founder dashboard | 1+ post/week repurposed across 3 channels |
| 4 | Under 5 min | Auto-routed with 1 qualifier | Brand guidelines + 20 assets/mo | Most ops automated, weekly reports | Bi-weekly post + 1 channel |
| 3 | Under 30 min | Manual routing same-day | Brand guidelines doc + designer | Some Zaps + reports | Monthly post |
| 2 | Under 4 hours | Manual routing within 24h | Inconsistent brand, ad-hoc designer | Mostly manual + spreadsheets | Quarterly post |
| 1 | Same day | Lead-list dump + sporadic follow-up | No brand system; founder choices | All manual | Sporadic / random |
| 0 | Next day or worse | No qualification at all | Nothing recognisable | Spreadsheets only | None |
4. How to interpret your total
Sum the 5 scores out of 25:
- 21-25 - Healthy. Polish the lowest-scoring loop. You are in the top 5% of mid-market operators on system discipline.
- 16-20 - Leaking. Fix the lowest 2 loops. The leak is meaningful but not catastrophic. 60-90 day window to recover.
- 11-15 - Hemorrhaging. The 21-day closed-loop deployment fixes 3+ loops at once. Stop investing in any individual function until the loops are wired.
- 0-10 - 2022 ops in a 2026 market. The fix is not 5 small projects; it is one closed-loop sprint with a single goal: lift every loop above 3 in 90 days.
5. How to pick the fix priority
The lowest-scoring loop wins, regardless of total. A firm scoring 22/25 with a 2/5 inbound loop should fix inbound first - the leak is concentrated. A firm scoring 14/25 with three loops at 3 should not "fix everything"; it should pick the loop with the highest revenue yield and fix that one in 21 days.
Revenue-yield rule of thumb:
- If you spend money on ads or SEO, Inbound and Qualification loops have the highest yield. Fix those first.
- If you sell to ecom or DTC and brand recognition matters, Brand and Content loops have the highest yield.
- If you are services with consistent inbound but operational drag, Ops loop has the highest yield. The 25 hours a week reclaimed convert directly to closed deals.
Pair this with The 25-Hour Week for the ops loop, The 90-Second Inbound Loop for the inbound loop, and The Brand DNA Sprint for the brand loop.
6. Common misconceptions
- "I can fix all 5 loops at once."
- You cannot. Trying to lift 5 loops simultaneously fragments attention and moves none of them. Pick the lowest, deploy in 21 days, then move to the next. The 90-day arc lifts 3 loops cleanly. The 6-month arc lifts all 5.
- "My total score is the only thing that matters."
- It is not. A 21/25 with one loop at 1 is worse than a 19/25 with all loops at 3-4. The minimum is the constraint. Theory of constraints applies to business systems too.
- "My business is too small to need this."
- The framework is designed for $2-30M revenue mid-market. Below $2M, simpler diagnostics apply. Above $30M, you have specialised teams running each loop and need a different framework. The score is calibrated for the band where one founder still needs to see all 5 loops on a single page.
What to ship this week
Run the Closed Loop Score in the next 5 minutes. Score every loop honestly - inflated scores cost you the diagnostic. The output gives you a single fix priority and the 21-day deploy path.
Then book a 30-minute system review if the lowest-scoring loop is below 3. The 30 minutes is enough to scope a 7-21 day fix and answer whether it is the kind of thing one of the founders should ship for you, or something your existing team can run with the framework.
Mid-market businesses do not lose because they pick the wrong CRM or hire the wrong VP. They lose because the loops between functions leak revenue at every handoff and nobody owns the loop. Score the loops. Fix the lowest. Compound the rest. The 5-minute audit is the cheapest diagnostic in business; the 21-day fix is the cheapest intervention. Both happen this month or they do not happen.
Frequently asked questions
What is the Closed Loop Score?
The Closed Loop Score is a 5-minute self-audit that scores 5 business loops (inbound, qualification, brand, ops, content) each on a 0-5 scale. Total out of 25 indicates business health: 21+ healthy, 16-20 leaking, under 16 hemorrhaging. The lowest-scoring loop becomes the fix priority regardless of total score.
How long does the Closed Loop Score take to run?
Five minutes if you know your numbers. The 5 loops each have a clear scoring rubric. Most mid-market operators can rate themselves in under 60 seconds per loop. The scored output maps to a 7-21 day fix path per loop.
Why 5 loops and not more?
Five is the largest number of independent loops a $2-30M services or ecom firm can hold in working memory. Adding loops 6-10 (analytics, finance, hiring, support, partnerships) makes the audit harder to act on. The 5 loops in scope cover roughly 90% of where mid-market revenue actually leaks per the audit data luup ran across 30+ businesses in 2025.
What if my total score is below 10?
You are running 2022 ops in a 2026 market and the gap is the entire reason your competitors are pulling ahead. The fix is not 5 small projects; it is one closed-loop deployment in 21 days. The loops are interconnected enough that fixing the lowest 2 typically lifts the others by 1-2 points each.
Can I run the Closed Loop Score on a competitor?
Partially. You can score their inbound (form-fill response time), brand (asset cadence on social), and content (post frequency) from outside. Qualification and ops require insider data. The external 3-loop score is enough to decide whether they are systemically ahead or just better at one tactic.
