Client & Vendor Intelligence Platform

Converted historical relationship knowledge into reusable organizational intelligence.

Delivered

Business value

Every client relationship has an owner and a next step, and every vendor evaluation starts from what the company already knows.

01

The request

From · Teams choosing and reviewing clients and vendors

The company already had valuable experience from past client and vendor relationships, but it was fragmented across employees, project history and operational tools — so it could not be reused consistently when evaluating future relationships.

  • Pain point 01

    Years of client and vendor history sat in cluttered, duplicated records across old tools and projects.

  • Pain point 02

    Relationships went quiet with no one assigned to follow up.

  • Pain point 03

    Each vendor evaluation started from scratch, and one person’s feedback couldn’t be compared with another’s.

02

What I built

  1. 01A cleaned, de-duplicated relationship base rebuilt from years of cluttered historical records
  2. 02A CRM for clients: companies linked to parent groups, contacts with owners and tiers, and re-engagement tasks for relationships that have gone quiet
  3. 03A VRM for vendors: structured profiles, engagement history and an eight-axis scorecard combining objective signals with team ratings
  4. 04Operating dashboards for both — coverage, re-engagement status, scorecard completeness and tiers
  5. 05Authenticated, role-based access from day one
03

Try it — explore the CRM and VRM

A simplified version of both workspaces. In the CRM, open a company and work its re-engagement tasks. In the VRM, open a vendor and see how a scorecard becomes complete and earns a tier.

How to use
  • All companies, people and numbers are fictional.
  • CRM: tick a re-engagement task and watch the contact turn active and the dashboard update.
  • VRM: open Rowan Vega and submit the team rating — the scorecard completes and a tier is assigned.
  • The real scoring weights are withheld; this demo averages the axes equally.

How I thought about it

  1. 01

    Clean the history first

    Reusable intelligence is only as good as the records underneath it, so the old data was consolidated, de-duplicated and structured before anything was built on top.

  2. 02

    Make feedback comparable

    Internal feedback is collected in a fixed format so it can be compared across organizations and over time.

  3. 03

    Turn data into follow-up

    Every quiet client relationship gets a re-engagement status, an owner and a task — so the CRM drives action, not just storage.

05

How it was delivered

Run as a project: from the team’s request to something people use every day.

  1. 01
    Intake

    Collected what teams need to know when choosing, reviewing or reconnecting with a client or vendor.

  2. 02
    Clean up

    Consolidated and de-duplicated years of cluttered historical records from past projects and old tools.

  3. 03
    Design

    Designed the data model — company hierarchy, owners, tiers, re-engagement status and the eight-axis scorecard.

  4. 04
    Build

    Built the CRM and VRM workspaces, re-engagement tasks, rating forms, dashboards and role-based access.

  5. 05
    Roll out

    Assigned owners, connected team ratings to project close, and handed the workspaces to the teams.

06

Result

BeforeCluttered, duplicated history spread across tools and projects
AfterOne cleaned, structured relationship base with parent groups, owners and tiers
BeforeQuiet client relationships had no follow-up
AfterRe-engagement status and tasks, each with an owner
BeforeEach vendor evaluation started from scratch
AfterEight-axis scorecards and tiers, assigned only from a complete scorecard
Historical client and vendor knowledge became a reusable organizational asset instead of information scattered across tools, projects and individual memory.

Organizational memory, not only a database

The system holds what the company has learned about each organization it works with:

  • Relationship history
    • Unified organization records
    • Client · vendor
  • Previous collaboration
    • Past projects
    • Who worked with them
  • Internal feedback
    • Structured, comparable
    • From people who worked with them
  • External signals
    • Objective business signals
  • Scorecards
    • Consistent framework
    • Weights withheld
  • Access
    • Authenticated
    • Role-based

That makes it the basis for consistent evaluation and organizational memory that outlasts individual employees and individual projects.

Scorecard

The scorecard combines objective external and business signals with structured feedback from internal points of contact who previously worked with the organization.

The score informs; a person decides
The internal weighting is intentionally not shown.

Scoring is requested inside each project document as part of project close, so evaluation happens in the flow of project work rather than as a separate exercise. Where scoring is triggered — Case 04 →
