CAP Table Auditor Backend

CAP Table Auditor Backend Template
Audit Shareholder Changes and Funding Rounds

Q: What evidence do cap table auditor reviewers expect to see in a well-run program?

A CAP Table Auditor backend is a BaaS schema and API for tracking shareholder logs, round history, and dilution alerts: Shareholder, OwnershipLog, FundingRound, and DilutionAlert.

Q: How should cap table auditor teams structure reviews, approvals, and exceptions in one system?

It includes Shareholder (legalName, email, ownershipPercent), OwnershipLog (shareholder, actionType, effectiveDate), FundingRound (roundName, closingDate, preMoneyValuation, postMoneyValuation), and DilutionAlert (shareholder, thresholdPercent, triggeredAt, resolvedAt, status), plus ER diagram, API playground, and an AI Agent prompt.

Q: Can this cap table auditor model accommodate new controls as regulations or contracts change?

Back4app provides managed database, auth, real-time queries, and flexible schema so you can ship shareholder logs, round history, and dilution alerts without running your own backend.

Q: How do I query shareholder logs with Flutter?

Use the Shareholder and OwnershipLog classes to load ownership history and render audit details in a Flutter screen.

Q: How do I manage cap table auditor permissions in Next.js server actions?

Use a server action to create a Parse Object for OwnershipLog with a shareholder pointer and actionType, then validate the change in Cloud Code.

Q: Can React Native cache funding rounds offline?

Yes. Pin FundingRound records in Local Datastore so reviewers can browse round history without a network connection.

Q: How do I prevent unauthorized dilution alert edits?

Use Cloud Code beforeSave on DilutionAlert to verify the user role and reject changes that bypass review policy.

Q: What is the best way to show cap table data on Android?

Query Shareholder, OwnershipLog, and FundingRound classes to build a review screen for ownership, round history, and alerts.

Q: How does the shareholder review flow work end to end?

Users log in, open the shareholder list, inspect OwnershipLog entries, review FundingRound history, and resolve DilutionAlert items when the ownership thresholds are acknowledged.

A production-ready CAP Table Auditor backend on Back4app with shareholder logs, funding round history, and dilution alerts. Includes ER diagram, data dictionary, JSON schema, API playground, and an AI Agent prompt for fast setup.

Key Takeaways for CAP Table Audits

This template gives you a CAP Table Auditor backend with shareholder logs, round history, and dilution alerts so operations teams can review ownership changes quickly.

Shareholder logs in one model — Store each OwnershipLog with the shareholder, actionType, and effectiveDate fields for a clear audit trail.
Round history stays queryable — FundingRound records capture roundName, closingDate, preMoneyValuation, and postMoneyValuation.
Dilution alerts are explicit — Use DilutionAlert thresholdPercent and triggeredAt to flag ownership changes before they drift too far.

What Is the CAP Table Auditor Template?

When cap table auditor teams operate across sites, consistent taxonomy prevents “same problem, five different names” in the audit trail. It is rarely a single bug — it is drift. Back4app keeps Shareholder, OwnershipLog, FundingRound, and DilutionAlert timestamped and attributable — the baseline cap table auditor teams need when scrutiny arrives. The schema covers Shareholder (legalName, email, ownershipPercent), OwnershipLog (shareholder, actionType, effectiveDate), FundingRound (roundName, closingDate, preMoneyValuation, postMoneyValuation), and DilutionAlert (shareholder, thresholdPercent, triggeredAt) with auth and audit-friendly relationships already defined. Connect your preferred frontend and start reviewing cap table changes sooner.

What you get in the Cap Table Auditor template

The best cap table auditor dashboards are boring because the underlying entities are clean — not because someone massaged a spreadsheet at midnight.

This summary orients teams around Shareholder, OwnershipLog, and FundingRound before anyone dives into ER diagrams or JSON exports.

Core CAP Table Auditor Features

Every technology card in this hub uses the same CAP Table Auditor schema with Shareholder, OwnershipLog, FundingRound, and DilutionAlert.

Shareholder registry

Shareholder stores legalName, email, and ownershipPercent.

Shareholder log history

OwnershipLog links a shareholder to actionType and effectiveDate.

Round history tracking

FundingRound captures roundName, closingDate, preMoneyValuation, and postMoneyValuation.

Dilution alerts

DilutionAlert stores shareholder, thresholdPercent, and triggeredAt.

Why Build Your CAP Table Auditor Backend with Back4app?

Back4app gives your auditor the Shareholder, OwnershipLog, FundingRound, and DilutionAlert primitives it needs so the team can focus on review logic instead of server maintenance.

•Audit trails tied to OwnershipLog: Each OwnershipLog entry links a shareholder to an actionType and effectiveDate, which makes ownership changes easy to inspect.
•Round history from FundingRound: FundingRound keeps roundName, closingDate, preMoneyValuation, and postMoneyValuation in one queryable object.
•Alert logic around DilutionAlert: Use thresholdPercent and triggeredAt on DilutionAlert to spot ownership movement before it becomes a reporting issue.

Build a cap-table review backend on one schema that keeps shareholders, rounds, and alerts consistent across clients.

Core Benefits

A cap table backend that keeps audit data structured and reviewable.

Faster shareholder review

Use Shareholder and OwnershipLog instead of stitching ownership changes across spreadsheets.

Round history at a glance

FundingRound fields such as roundName and postMoneyValuation make financing comparisons easier.

Alert-driven oversight

DilutionAlert gives reviewers a clear trigger when ownership falls below a thresholdPercent.

Permission-aware records

Use ACL and CLP to limit who can create, edit, or inspect shareholder and round records.

One API for audit clients

REST and GraphQL can serve dashboards, admin tools, and mobile review flows from the same schema.

Prompt-based setup

The AI Agent prompt can generate the backend skeleton, class setup, and starter review screens.

Build with AI Agent

Use the Back4app AI Agent to generate a real CAP Table Auditor app from this template, including frontend, backend, auth, and shareholder, round, and alert flows.

Back4app AI Agent

Ready to build

Create a CAP Table Auditor app backend on Back4app with this exact schema and behavior.

Schema:
1. Shareholder: legalName (String, required), email (String, required), ownershipPercent (Number, required); objectId, createdAt, updatedAt (system).
2. OwnershipLog: shareholder (Pointer to Shareholder, required), actionType (String, required), effectiveDate (Date, required), note (String); objectId, createdAt, updatedAt (system).
3. FundingRound: roundName (String, required), closingDate (Date, required), preMoneyValuation (Number, required), postMoneyValuation (Number, required); objectId, createdAt, updatedAt (system).
4. DilutionAlert: shareholder (Pointer to Shareholder, required), thresholdPercent (Number, required), triggeredAt (Date, required), resolvedAt (Date), status (String, required); objectId, createdAt, updatedAt (system).

Security:
- Restrict shareholder and round edits to approved roles. Validate financial fields and alert thresholds in Cloud Code.

Auth:
- Sign-up, login, logout.

Behavior:
- List shareholders, inspect ownership logs, review round history, and manage dilution alerts.

Deliver:
- Back4app app with schema, ACLs, CLPs; frontend for shareholder logs, round history, and alert review.
