Completed sample proof package

Evidence chain - Lucía Torres

Every artifact below was produced in a scored workshop inside the 60-Day Founder program. Scores are rubric-graded (70+ passes a gate) - this page renders exactly what the program recorded.

This illustrative founder and company show how a completed evidence chain appears. The scores and outcomes are sample data.

Carga Clara

From document rework to four paying teams

Lucía used each market signal to narrow the product, choose the next test, and build a proof chain she could defend.

  1. 1. Problem evidence

    34 conversations exposed costly document rework

    Independent freight forwarders spent 6 to 10 hours per shipment reconciling customs packets across email and WhatsApp.

  2. 2. Product decision

    One preflight workflow replaced a broad platform plan

    The MVP focused on finding missing fields and producing a cited checklist in under three minutes.

  3. 3. Market test

    Eight pilot teams tested the same activation event

    The team tracked review time, first-pass acceptance, and whether an operations team kept using the workflow.

  4. 4. Measured result

    Four teams paid and review time fell to 18 minutes

    The product reached $1,600 MRR, 82% first-pass acceptance, and a clear next mission: test broker referrals.

Investor handoff memo

Investor-ready sample evidence chain

8/8

Thesis

Carga Clara reduces freight-document review time for independent Latin American forwarders and has converted half of its pilot teams into paying customers.

Closed-loop traction

34 customer conversations, 8 pilots, 4 paying teams, $1,600 MRR Product analytics: median review time fell from 74 to 18 minutes; 82% of packets passed without correction Payments: four active subscriptions at $400 per month

Evidence chain

  • Compliance Map: 90/100 - The checklist names data boundaries, human review, and deletion controls.
  • VC Proof Packager: 89/100 - The investor narrative connects a narrow buyer, paid traction, and the next risk.
  • Idea Validation Sprint: 88/100 - The problem, buyer, and weekly validation test use specific evidence.
  • Build Brief Generator: 87/100 - The build brief gives an agent testable inputs, outputs, and constraints.
  • MVP Architecture: 86/100 - The MVP tests one workflow with measurable acceptance criteria.

Next updates

  • Test whether broker referrals can acquire five more paying teams while keeping sales payback under three months.

Idea Validation Sprint

88/100v3

The problem, buyer, and weekly validation test use specific evidence.

Problem statement
Independent freight forwarders in Colombia spend 6 to 10 hours per shipment reconciling customs documents across email and WhatsApp. Missing fields create rework and shipment delays.
Riskiest assumption
Operations teams will trust an AI preflight check before sending documents to a customs broker. We tested this with 34 interviews and 112 document packets.

Market Research Sprint

84/100v3

The beachhead links a countable segment to observed buying behavior.

Beachhead segment
Colombian freight forwarders handling 20 to 150 export shipments per month with operations coordinated through email and WhatsApp.
Market Findings
Eight teams joined a pilot. Four converted to paid plans at $400 per month after measuring document-review time and correction rates.

MVP Architecture

86/100v3

The MVP tests one workflow with measurable acceptance criteria.

Core feature
Upload or forward a shipment packet, extract required fields, flag missing evidence, and produce a cited preflight checklist in under three minutes.
Platform decision
Ship one freight-document product. Reuse extraction and policy components inside that product without presenting a platform to customers.

Cost Architecture

82/100v3

The model connects inference cost, price, usage, and gross margin.

Cost per session
$0.19 per document packet at current volume: OCR $0.05, extraction $0.08, policy retrieval $0.02, and review generation $0.04.
Unit Economics
At 600 packets per customer per month, variable cost is $114 against a $400 subscription, producing a 71.5% gross margin before support.

Compliance Map

90/100v3

The checklist names data boundaries, human review, and deletion controls.

Risk classification
Decision support for freight operations. The product does not submit customs declarations or make legal eligibility decisions.
Compliance Posture
Tenant isolation, encrypted storage, 30-day source-document retention, cited field extraction, human approval before export, and account-level deletion.

Go-to-Market Sprint

85/100v3

The launch plan ties one channel to a repeatable paid-pilot motion.

Primary channel
Founder-led outreach through freight associations and referrals from customs brokers.
Launch Motion
Offer a 10-packet document audit, measure correction time, then convert teams that save at least four hours into a 30-day paid pilot.

Build Brief Generator

87/100v3

The build brief gives an agent testable inputs, outputs, and constraints.

TACOMORE brief
Task: preflight freight documents. Context: shipment type, destination, broker checklist. Output: cited missing-field report. Format: JSON plus review UI. Role: freight operations analyst. Examples: 25 approved and 15 rejected packets.
Acceptance Criteria
Reach 95% required-field recall, cite each extracted value, finish in under three minutes, and require a human approval before export.

VC Proof Packager

89/100v3

The investor narrative connects a narrow buyer, paid traction, and the next risk.

Investment thesis
Carga Clara helps independent Latin American freight forwarders catch document errors before customs handoff. Four paying teams produce $1,600 MRR, and pilots cut median review time from 74 to 18 minutes.
Evidence Chain
34 interviews → 8 pilots → 4 paying teams → 112 packets reviewed → 82% accepted without correction → 63% week-four team retention.
