Switching cap table platforms before your Series A: What investors and counsel check

Switching cap table platforms before a Series A is common, and the real question is whether your investors and counsel will accept the new platform. In the diligence processes we see on Cake, the people reviewing a cap table care far more about whether the records behind it are complete and accurate than about the logo on the software. Some funds do prefer or require a specific platform, though, so founders commonly ask early.

The question has become urgent for Pulley customers. Pulley is shutting down on December 8, 2026, and while it arranged a migration path to Carta, many founders are weighing other options and wondering whether moving elsewhere will create friction with a lead investor or law firm. The same question lands on investors, who have to decide what to tell every portfolio company on Pulley before the deadline. Our Pulley shutdown explainer covers the dates and mechanics.

This guide covers what investors and counsel check, what founders do when an investor names a platform, who is on Cake, what a migration involves, and how investors can keep a Pulley portfolio moving. It includes two short emails to adapt. To look at your own data first, get started free and view your imported cap table before choosing a plan.

Do investors and lawyers care which cap table platform you use?

Most investors and lawyers care about the quality of your records first and the platform second. A platform organizes what you put into it. It does not confirm that a SAFE converted correctly, that a board consent exists, or that a past option grant was properly approved.

That is why diligence tends to focus on the underlying paperwork: investors want to see every document behind the numbers.

There is one honest caveat: some funds do prefer or require a specific platform. Whether that applies to your round depends on your lead investor, so it is a question to ask rather than assume. We cover how founders handle that conversation below.

Who reviews a Series A cap table

Investors, counsel and finance each look at the same cap table for different reasons:

• ‍Investors want to confirm ownership after the round and that nothing unexpected sits behind the numbers. They commonly ask for the fully diluted cap table, SAFE and note terms, and round modeling.‍
• Company counsel wants to confirm that every issuance was properly approved and documented. They commonly ask for signed agreements, board and stockholder consents, and the transaction history.‍
• Finance wants to confirm that equity records tie to the books and to compliance requirements. They commonly ask for the current 409A, ASC 718 records where relevant, and grant and exercise exports.

What investors and counsel check in a Series A cap table

Investors and counsel check six things in a Series A cap table: ownership, instrument terms, signed documents, compliance records, history, and access. The table below shows what each check looks like in practice and where the matching information lives in Cake.

On the history row: Cake's audit log records which actions were taken and which user took them, with timestamps. It does not capture before and after field values or document-level review trails, so many companies rely on the signed documents on each stakeholder profile as the detailed record.

What founders commonly do when an investor asks for a specific platform

When a lead investor names a platform, founders commonly start by asking why and what they actually need from it. The answer is often a specific report, a read-only view, or a data export.

Questions founders tend to ask the fund include:

• Does the fund require a particular platform, or prefer one?
• Is there a specific report or export format the fund uses for portfolio reporting?
• Does the fund need ongoing access to the cap table, or periodic exports?
• Would the fund's counsel review the migrated cap table before closing?

Sometimes the answer is that the fund requires one platform, and that settles it. We would rather say that plainly than pretend otherwise. When the answer is more flexible, founders typically confirm the requirements in writing and share what the new platform can provide.

This is a decision for you, your investor and your counsel, and Cake can connect you with legal and finance experts if you want help.

Who is on Cake: law firms and companies

Several of the largest US startup law firms work inside Cake, alongside thousands of growing companies. The figures below are the same ones shown on our momentum page, restated here as text.

Scale. Companies on Cake have raised more than $10 billion, as of September 2026, based on publicly available capital raise data.

Law firms. Matt Secrist, a partner at Taft Law, describes the working relationship this way:

"As a US attorney, our partnership with Cake has been invaluable in guiding clients through cap tables and equity incentive plans seamlessly.^{— Matt Secrist, Partner at Taft Law}

Companies. Whimsical manages equity on Cake, and its team shares why they chose it in their customer story.

These are observations of who uses Cake, not endorsements by any firm of Cake over other platforms.

Switching before the round: timing and what migration involves

Founders commonly switch before diligence starts, because a cap table moved mid-process puts two sets of records in front of reviewers at once.

The mechanics are less involved than most expect: Cake's Customer Success team builds the cap table from exports of your existing platform, at no cost, usually within a few business days.

For a Pulley migration, the steps look like this:

1. Export three reports from Pulley: the Cap Table file, the Stakeholders report and the Vesting Details report.

2. Download the paperwork separately. Exports do not include signed grant letters, SAFEs and convertible notes, board consents or past 409A reports. These must be saved while you can still log in. Pulley's help center describes a "Download All" option in its data room that returns one ZIP of uploaded agreements, board consents and other files, with the folder structure kept.

3. Send the files to Cake. Customer Success builds the cap table and reconciles it against your export.

4. Review before go-live. Cake does not review source documents such as board consents line by line, so you and your counsel check the imported data against your records.

Our walkthrough on how to migrate from Pulley to Cake has the full checklist, and the top Pulley alternatives compares the options.

If you're an investor with portfolio companies on Pulley

Investors with portfolio companies on Pulley can cut the effort across the portfolio by sending one standard email, asking each company to name an owner and a target date, and tracking three milestones before Pulley shuts down on December 8, 2026. The platform choice stays with each company and its counsel, but a shared process keeps any company from reaching the last week without a plan.

"Minimal effort" depends on the route, so it helps to be specific about what each one asks of a founder:

• Pulley's arranged Carta route. Per Pulley's FAQ, the company opts in through Pulley by November 30, 2026 and signs a new Carta agreement, and Carta runs the migration. Carta has committed to matching current Pulley pricing for the first year and crediting unused prepaid Pulley time, with annual or quarterly billing only. The company reviews the migrated data afterwards.

• An independent platform such as Cake. Pulley has said it will not assist migrations to providers other than Carta. The company exports three reports from Pulley and downloads its signed paperwork, then Cake's Customer Success team builds the cap table at no cost and reconciles it against the export. The company can view the migrated cap table before choosing a paid plan, and reviews it before go-live.

Milestones investors commonly track across a portfolio:

1. Migration started: an owner is named and the export is underway.

2. Data reconciled: the new cap table matches the old one, and the company has signed off.

3. New platform live: the team is invited and Pulley is no longer the source of record.

Many investors also ask each company to save a backup before Pulley closes, whichever platform it picks: the cap table export, the Stakeholders and Vesting Details reports, and every signed agreement, board consent and 409A report.

Here is a short email an investor can adapt for a portfolio. It is general information, and your counsel can advise on what to send:

Subject: Pulley is shutting down on December 8: please confirm your plan

Hi all,

Pulley is shutting down on December 8, 2026. Could each of you reply by [date] with:

1. Who owns the migration at your company

2. The platform you are considering and your target completion date

3. Confirmation that you have saved your cap table export, Stakeholders report, Vesting Details report and signed documents (agreements, SAFEs, notes, board consents and 409A reports)

Pulley's arranged option is Carta, with an opt-in deadline of November 30. Independent platforms such as Cake also offer migration support, and one comparison is here: https://www.cakeequity.com/guides/switching-cap-table-before-series-a. The choice is yours and your counsel's. We just want everyone moving early.

Keep a diligence bundle ready

A diligence bundle is a standing folder of the records every Series A reviewer asks for, and founders who keep one ready tend to spend less time on information requests. It does not depend on which platform you use.

A typical bundle includes:

• A current cap table export, plus the transaction history behind it
• Executed SAFEs, convertible notes, option grants and share agreements
• Board and stockholder consents for each issuance
• The latest 409A valuation and ASC 718 records where relevant
• Option plan documents and a record of who has access to the cap table

Cake supports the export side with an XLSX cap table export, CSV and PDF shareholder lists, noteholder and equity grant exports, and a transaction history export. Many founders also share the finished bundle with investors through a data room during a raise. Signed documents sit on the stakeholder profile, so pulling one does not mean hunting through shared drives.

An email to send your lead investor and counsel

Many founders handle this with one short email that asks the platform question before it becomes a blocker. The template below is a starting point you can adapt. It is general information, not legal advice, and your counsel can tell you what to include for your situation.

Subject: Cap table platform for our Series A

Hi [Name],

We are finalizing our cap table tooling ahead of the round and are considering moving to Cake (cakeequity.com). Before we commit, could you let us know:

1. Does the fund require or prefer a specific cap table platform?

2. Is there a report, export format or level of access you need from us for portfolio reporting?

3. Would you or our counsel like to review the migrated cap table before we go live?

Cake keeps signed documents and a full transaction history on file and supports standard exports for diligence. Several of the largest US startup law firms work inside the platform. There is a short overview for counsel and investors here: https://www.cakeequity.com/guides/switching-cap-table-before-series-a.

Happy to jump on a call if easier.
