How the AI
score works

Mikata ranks Japanese small-business listings for a specific acquisition thesis: improve earnings with technology, while owning a durable real-world core that can retain the value created.

Target profile Compressible payroll behind a defensible, non-compressible core.

01

Three questions, in sequence

A company with highly automatable work is not automatically an attractive acquisition. If competitors can reproduce the same savings, that value may pass to customers through lower prices. The score therefore separates improvement potential from durability.

A

Compression upside

How much earnings improvement could come from compressing or redirecting labour?

50% of upside
B

Revenue upside

What is the strongest credible route to additional revenue?

50% of upside
C

Durability

Would the asset remain scarce if machine intelligence became abundant and cheap?

Multiplier

A and B measure how much the business could improve. C determines how much of that opportunity survives the durability scenario.

02

Evidence moves a prior

Each axis begins at a prior score. The current priors are neutral defaults of 50; industry- and revenue-specific priors have not yet been calibrated from investment outcomes. Listing evidence supplies an integer delta rather than a new absolute score. The server ignores model-supplied totals and recomputes every axis, cap and composite.

Axis scoreclamp(prior + evidence delta, 0, 100)
Evidence limits
Listing evidenceMaximum movementWhat it means
Thin±10Short teaser or material fields missing
Moderate±18Enough facts to support a direction
Rich±25Detailed operating and financial evidence

Evidence density caps individual axis movement. Confidence is separate: it discounts the combined A/B upside later. The application recalculates the fixed arithmetic; the model interprets evidence and proposes deltas.

03

Axis A · Compression upside

Axis A estimates the economically addressable labour pool. It distinguishes work that software can absorb from physical execution and accountable judgement that must remain.

Workforce assumptions
Work typeExamplesCompression rate
TransactionalOrders, invoicing, forms, data entry80%
Repetitive judgementQuoting, dispatch, shifts, inspection60%
Tacit expertiseCraft judgement, on-site diagnosis30%
Accountable judgementNegotiation, supervision, licensed sign-off20%
Non-knowledge workPhysical execution or required presence0%
Compressible payroll Σ headcount × occupational monthly wage × 16.7 × compression rate Wages use the mapped Japanese government occupation statistic. The 16.7 factor approximates loaded annual employment cost.

Knowledge-work ratio

Compressible-strata headcount divided by total headcount.

Compression leverage

Estimated compressible payroll divided by current EBITDA.

The target zone

< 0.30Too little leverageA capped at 45
0.30–0.75Target zoneNo KWR cap
> 0.75Too little durable coreA capped at 40

If no non-compressible core is identified—such as a licence, physical asset, local density, certification, installed capacity, or embodied service—Axis A is capped at 40 regardless of the ratio.

Compression is not immediate EBITDA. In Japan, savings generally emerge through attrition, avoided replacement, or productive redeployment. The conversion horizon is a diligence signal, not part of the formula.

04

Axis B · One credible growth engine

Four revenue plays are scored independently. Axis B takes the maximum because a deal needs one strong growth engine, not four average ones.

B1

Capacity unlock

Observed demand exceeds manual throughput, available labour, operating hours, or installed capacity.

B2

Go-to-market upgrade

A viable offer has weak commercial machinery: referrals only, owner-led sales, poor web presence, or no segmentation.

B3

Internationalisation

An exportable product works in Japan but has little international revenue.

B4

Supply-chain resilience

Owned production, certifications, capacity, and traceable inputs could serve buyers diversifying critical suppliers or reshoring production.

Axis Bmax(B1, B2, B3, B4)

A speculative play can dominate the result. Evidence limits and the confidence discount restrain that risk; the winning play still requires diligence.

05

Axis C · Durability

If intelligence is abundant and cheap around 2030, is this company still worth owning?

The thesis is that information processing becomes less scarce while licences, installed assets, local density, physical capacity, and hard-to-hire labour remain scarce for longer.

Durability design
SignalDesign weightMore durableLess durable
Constraint type25%Licence, assets, local densityMatching or unprotected relationships
Occupation tightness25%Difficult to hireSurplus applicants
Intermediation20%Earns from doing workEarns from transaction friction
Demography15%Benefits from ageingDepends on population growth
Competitor adoption10%Fragmented, slow peersWell-capitalised peers
Robotics surface5%Automation adds capacityNo useful deployment surface

These weights describe the investment design, but Axis C is not calculated as a literal weighted spreadsheet. The model considers the signals and evidence, supplies a delta, and the application calculates prior plus delta.

07

Gates and disposition

Four structural gates are assessed after scoring. Each is pass, fail, or unknown. Missing broker information does not count as a failure.

Size floorSector or structureLicence transferabilityPrice expectation
Reject when Axis C < 30 or any gate fails

A numerical score is retained for validated rejected records. That preserves the distinction between an economically interesting business and a structurally eligible acquisition. Responses with unverifiable evidence, invalid deltas, missing fields or schema errors are retried and cannot replace a trusted score.

08

How to use the output

Read the base composite and final score together. A large gap indicates attractive improvement potential with weak durability. A small gap means more of the opportunity is supported by durable scarcity.

The score is

  • A sourcing and ranking aid
  • A structured expression of an investment thesis
  • A way to expose assumptions and evidence gaps

The score is not

  • A probability of success
  • A forecast IRR or valuation
  • A substitute for diligence
  • An automatic investment decision

Current limitations

  1. 01

    Neutral priors remain provisional and need calibration from human comparisons and investment outcomes.

  2. 02

    Marketplace descriptions are incomplete and uneven; the score can partly reflect broker disclosure quality.

  3. 03

    Workforce composition and wages are screening proxies, not company-level payroll diligence.

  4. 04

    Conversion horizon and risk flags inform review but do not enter the numeric formula.

  5. 05

    Axis C is a scenario weight, not a prediction that abundant intelligence will arrive on a fixed schedule.

The goal is not to remove judgement. It is to make the judgement consistent, inspectable, and easier to challenge.
