Colabra vs In-house RAG

Put your team’s effort into the deal review.

Put your team’s effort into the deal review.

Colabra packages the diligence workflow around evidence, findings, requests, and investment deliverables. Choose it when the priority is running a repeatable buy-side process and a dedicated product fits your requirements. Evaluate that ready-made structure against the engineering and operational work your own implementation would require.

Start from a deal workflow

Evaluate a product organized around M&A review requirements and deliverables.

Inspect the work product

Judge the source-linked findings, models, and memos your reviewers will actually use.

Keep ownership clear

Give the deal team an explicit place for the evidence, questions, and accepted conclusions.

Follow a finding into the model and memo →

Decide whether owning the system is part of your advantage.

Building is worth evaluating when your team has unusual requirements, an engineering owner, and a reason to maintain differentiated infrastructure. Buying is worth evaluating when the main objective is a repeatable diligence process. Compare complete operating systems, not a prototype chat interface against a finished workflow.

In-house RAG

An in-house retrieval-augmented generation system combines search over private material with model-generated answers. Its capabilities depend on the implementation: citations, permissions, structured workflows, and work-product generation can all be built around it.

Colabra

Colabra is an AI workspace for M&A due diligence, organized around deal files, review requirements, findings, requests, and reports. Its focus is helping buy-side teams turn sell-side material into source-linked findings, financial models, and investment memos.

Where each approach fits

Consider In-house RAG when…

You have distinctive requirements, engineering ownership, and a reason to control the implementation. Include development, evaluation, permissions, operations, and support in the scope. A production system needs an accountable owner after the initial demonstration.

Consider Colabra when…

The objective is to operate diligence rather than develop an internal product. Evaluate the commercial workflow against your requirements and the cost of maintaining an equivalent process. Product fit and operating effort matter more than a headline model or retrieval choice.

Using them together

An internal system may solve a narrow analytical need while a commercial workspace holds the review record. Define interfaces around explicit inputs and reviewed outputs. Avoid duplicating the same ingestion and issue-management responsibilities without a clear benefit.

Three tasks to bring to the pilot

Use known positive and negative findings, duplicate and unreadable files, restricted documents, and a realistic source update. Give both workflows the same scope, access, and expected deliverable: a reviewed finding set with error analysis and a maintainable operating plan. Have the people who will own the work perform the review.

  1. 01

    Build the evaluation set before the interface

    Select known material issues, ambiguous cases, missing documents, and misleading near-matches. Preserve the expected evidence and reviewer rationale. Use that set to assess changes to retrieval, parsing, prompts, and models without relying on a few successful demonstrations.

  2. 02

    Test the permission boundary end to end

    Use two reviewers with different source access and ask overlapping questions. Include retrieved text, generated artifacts, caches, and logs in the review. Assign an owner for investigating a permission change that produces an unexpected result.

  3. 03

    Price the maintenance obligation

    Estimate ingestion repairs, evaluation work, access integration, model changes, incident handling, and user support. Include the engineer who maintains the system when comparing it with a commercial workspace. A low marginal model bill does not describe the full cost.

Judge the reviewed result

Agree the acceptance criteria before the demonstration. Record the evidence behind each assessment so the decision can be revisited after the pilot.

CriterionQuestion to answerHow to check
Evidence qualityCan a reviewer locate the controlling source and explain how it supports the exact conclusion?Record unsupported statements, incorrect references, and ambiguity that the output hides. A source link is useful only if the source substantiates the claim.
Coverage and exceptionsCan the team tell what was reviewed, what failed to process, and what is still missing?Seed a missing attachment and an unreadable file. The reviewer should distinguish incomplete evidence from a clean result and know what to request next.
Revision and handoffCan another person challenge the finding and update the work after new evidence arrives?Repeat one material change. Count the places that need manual updates and check whether the new memo still agrees with the supporting analysis.
Operating effortHow much setup, specialist review, administration, and coordination does the completed task require?Measure total reviewer time through an accepted deliverable. Include correction and handoff time, not only time to the first generated draft.

Use a simple result for each criterion: demonstrated, requires configuration, or unresolved. Do not turn an unanswered question into a feature claim. Ask for a follow-up demonstration when a material requirement remains unresolved.

Investment committee memo

Executive view

Resolve the earnings adjustment and currency difference before finalizing the investment case. Keep customer consent visible in the closing discussion.

Matters for attention

01
Earnings adjustment

The adjustment combines remediation with support. Separate ongoing costs before accepting the full add-back.

Management earnings bridge · note 4
02
Currency reconciliation

The stated rate implies $1,296,000, leaving a $24,000 difference to explain.

Revenue schedule · European subsidiary
03
Customer consent

Confirm whether the proposed transaction triggers consent before relying on the contract at close.

Follow the complete workflow

Compare the cost of the complete workflow

Start with licenses and services already in place. Add implementation, permitted usage, storage, external reviewers, specialist review, support, and the internal time needed to maintain the process. Request a written quote for your actual configuration; a generic seat price will not describe every deployment.

Before the pilot

Confirm the product edition, available connections, document limits, access roles, and who can configure the workflow. Agree which sample material is authorized for the evaluation and which deliverables the reviewers must produce.

Before adoption

Review the proposed data handling, retention, access, and contractual arrangements. Test export and handoff with the people who will own the deal record after close. Include source references and unresolved questions in that final package.

Compare total effort through the first accepted result and one meaningful revision. If your existing workflow performs well, keeping it is a valid outcome. If another approach wins, identify the specific task it improves and the changes needed to make that improvement repeatable.
