Vectig publishes this page, so read it knowing that. Below, we say plainly where another option is the better choice.

Visible puts updates, pitch decks, data rooms, and a fundraising pipeline in one product, and it has a free plan. Carta fits if your cap table already lives there. Cabal sends an update you wrote from your own inbox. Foundersuite pairs updates with an investor CRM for founders in an active raise. A doc plus email, or a general AI assistant, can carry a short investor list. Vectig is for founders who want the draft itself written from their numbers and their past updates.

How we compared

We looked at the first business days of the month, when the update has to go out, and asked the same questions of every option:

  • Who writes the draft? You, a template, an AI agent you bring, or the tool itself.
  • Does it carry last month forward? Whether your past updates and metric history shape this month’s draft.
  • Where do the numbers come from? Manual entry, connected sources, or paste.
  • Who read it? Per-investor engagement after the send.
  • What else is in the box? Decks, data rooms, investor databases, or a cap table. Useful if you need them, extra weight if you don’t.
  • What does it cost at your size? The entry price, and the tier where your recipients and data sources actually fit.

Every fact about another product comes from that vendor’s own website, checked in October 2026 and linked under Sources. We didn’t buy other vendors’ paid plans to test them. Where a vendor’s pages answer one of the questions above, we report what they say; where they don’t, we leave it out rather than guess, so ask the vendor directly. Prices are as listed, in US dollars, before tax. For the reasoning behind the questions, see how to choose investor update software.

The tools

Visible

Visible describes itself as being “for investors and founders.” On the founder side, its plans cover investor updates, KPI dashboards, pitch decks, data rooms, fundraising pipelines, and Visible Connect, its investor database. It also sells portfolio monitoring to venture firms.

Updates start from a template (the Visible Standard, a Y Combinator template, or one built by founders), embed KPIs as charts and tables, and go out as an email, a link, a Slack message, or a PDF. For drafting, Visible’s updates page describes asking your own AI agent to draft the next update directly in Visible, using the metrics and context it already has access to. Separately, when an investor collects data through Visible’s Requests, Visible AI can turn the founder’s response into a polished update. Engagement is tracked from the send: “Every open, every slide, every second.”

Best for: a founder who wants updates, deck sharing, a raise pipeline, and a data room in one tool, and wants to start free.

Pricing, as published:

  • Starter: free forever, no credit card. Monthly updates to 100 investors.
  • Base: $59/month billed annually ($69 billed monthly). Updates to 250 investors from your own domain.
  • Core: $129/month billed annually ($149 billed monthly). 500 investors and three integrations.
  • Growth: $199/month billed annually ($249 billed monthly). 1,000 investors and five integrations.

Good to know: every plan includes unlimited updates, and paid plans come with a 30-day refund. Integrations count against a per-plan limit, and “each unique data source counts as a single data integration.” Visible’s integrations page lists Stripe, QuickBooks, Xero, Mercury, and Google Sheets, among others.

Carta

Carta is cap table software with an Investor Relations hub, where you can “respond to requests, manage cap table access, and send updates.” Its Communication Center “gives you a record of what you’ve sent investors and tells you whether they’ve read it,” and you can set an expiration date on messages. You can add a one-time snapshot of your financials to an update by connecting your accounting software once, and those financial updates are accessible only through Carta, behind a login. Carta also offers a virtual data room for due diligence documents.

Best for: a founder whose cap table is already on Carta and who wants updates in the same place as ownership data and diligence documents.

Pricing, as published: Carta Launch is free for companies “with under 25 stakeholders and raised up to $1 million.” Carta’s plan comparison lists investor updates on all four packages: Launch, Build, Grow, and Scale. Paid packages are priced per stakeholder with a minimum annual fee, and the price comes from sales.

Cabal

Cabal sends investor updates as email: “Draft with your team, personalize every message with modern mail merge, and send from your own inbox.” Each recipient gets a private email instead of a BCC, and open and click tracking shows which investors engaged.

Best for: a founder who writes the update and wants it to arrive as a personal email from their own inbox, with tracking.

Pricing, as published: free to start. Cabal Mail Pro is $19/month per user and unlocks “collaborative drafts, engagement tracking, and unbranded emails.” Cabal’s Premium plans, from $49/month, are aimed at VC platform teams, deal sourcing, and sales orgs.

Foundersuite

Foundersuite is a fundraising platform built around an investor CRM and a database it describes as “216,000 LPs, VC and HNW including family offices.” Its investor updates let you add text, images, and KPIs, attach files, and see “who viewed it and for how long.” Its AI email generation drafts investor outreach.

Best for: a founder in an active raise who wants updates to sit next to a pipeline of prospective investors.

Pricing, as published: Basic is free forever, with no credit card. Paid plans are billed annually: Silver $745 a year, Gold $1,069, and Platinum $1,609. A data room is listed as a paid add-on on Gold and Platinum.

A doc plus email

You write in Notion or Google Docs from a template and send from your own inbox. Notion has a free plan. The setup is completely flexible and costs nothing new. You also do every step yourself: gather the numbers, write, check against last month, send, and follow up.

Best for: a pre-seed founder with a handful of investors and a steady monthly habit. Our investor update template and DIY stack guide cover the setup.

ChatGPT or Claude

A general-purpose assistant drafts fluent prose from whatever you paste in, and with a little setup it can hold standing context. Claude’s projects, for example, keep files and instructions together, so your past updates can sit in one place; projects are available on free accounts, up to five of them. Claude Pro is $17/month billed annually, or $20 billed monthly.

The rest of the workflow is yours: pulling this month’s numbers, checking them against last month, sending, and following up. Before you paste in financials, check your plan’s data settings. Anthropic, for example, lets Claude Free, Pro, and Max users choose whether their chats are used to improve its models. For transparency, Vectig’s drafts also run on Anthropic models, accessed through Anthropic’s API, as our privacy policy explains.

Best for: a one-off update, or a founder who enjoys maintaining their own prompt. Our investor update prompt works unchanged in ChatGPT or any capable model.

Vectig

Vectig is investor update software for venture-backed founders: it drafts your monthly update in your voice from your numbers and your past updates.

  • Your past updates as context. You paste a few past updates once. The narrative engine is conditioned on your prior updates, supplied as context — never used to train any model.
  • A draft on the 1st. Starting with your first full month, a draft is waiting at the start of each month.
  • Memory across months. It remembers what you told investors last month and calls out numbers that disagree with it.
  • Numbers. Stripe and Mercury connections are rolling out now. Manual entry is fully supported today.
  • Sending. Nothing goes to your investors until you press send, and there’s no setting that sends automatically.
  • Who read it. Each investor gets a personal link to the update, and Vectig records an open when that investor opens it. There’s no tracking pixel, so an investor who reads only in their inbox won’t show as opened.
  • Runway. The plan includes a cash flow forecaster with scenarios and a what-if simulator.

Best for: a funded founder who sends a monthly update to a real investor list, wants the first draft written from their own numbers and history, and wants next month’s draft to know what this month’s said.

Pricing: Solo is $49/month, or $39/month billed annually, with unlimited investor contacts, PDF export, and shareable links. It starts with a 7-day trial; you add a card at signup, and there’s no free plan. A 14-day money-back guarantee applies after your first charge. Team is $99/month and is set up on a call. Prices exclude tax.

Limits: no investor database, fundraising pipeline, deck hosting, or data room. Updates are sent from Vectig’s address (updates@vectig.com), not your own domain. The free investor update generator is one-shot: it needs no signup, but it doesn’t remember past months or write in your voice.

When Vectig isn’t the right fit

  • You want to pay nothing. Visible Starter, Cabal’s free plan, Foundersuite Basic, Carta Launch (if you qualify), and a Notion doc all cost $0. Vectig has no free plan.
  • You’re raising and need a pipeline. Visible and Foundersuite both pair updates with investor pipelines and an investor database. Vectig has none of these.
  • Updates must come from your own domain or inbox. Visible sends from your own domain from Base up, and Cabal sends from your own inbox. Vectig sends from its own address.
  • You need connected data sources today. Stripe and Mercury connections are rolling out now. Manual entry is fully supported today. If an automatic billing or bank feed is a hard requirement now, Visible’s integrations page lists Stripe, QuickBooks, Xero, and Mercury, among others.
  • Your cap table and investor documents live on Carta, and keeping everything in one place matters more to you than who writes the draft.
  • You’d rather write every word yourself and only need a clean send with tracking. Cabal is built for that.
  • Your security review requires a SOC 2 report. Vectig doesn’t claim one. Visible’s site lists SOC 2 Type II.
  • You’re a fund. Vectig is built for founders. Visible sells portfolio monitoring to venture firms.

Questions

What is the best investor update software for a seed-stage founder?

It depends on what you want taken off your plate. If you want to write the update yourself and send it well, Cabal or Visible's free Starter plan covers that. If your cap table is on Carta, its built-in updates are the low-effort choice. If the slow part is writing the draft and squaring it with last month, Vectig drafts it from your numbers and your past updates.

Is there free investor update software?

Yes. Visible Starter is free forever and sends updates to up to 100 investors. Cabal is free to start. Carta Launch is free for companies with under 25 stakeholders that have raised up to $1 million. Foundersuite Basic is free forever. Vectig has no free plan, but its investor update generator is free, needs no signup, and drafts a single update.

Can I just use ChatGPT or Claude to write my investor update?

Yes, and for a one-off it works well. The cost shows up month over month: you paste the numbers again, supply the context again, check consistency with last month by hand, and send and follow up from your own inbox. Our free investor update prompt is a good place to start.

Does Carta do investor updates?

Yes. Carta's Investor Relations hub sends updates, and its Communication Center tells you whether investors have read them. Carta's plan comparison lists investor updates on all four packages, including the free Launch package.

Which tools write the draft for me?

Vectig drafts the update itself each month, from your numbers and your past updates. Visible describes drafting through your own AI agent working directly in Visible, and its Requests product can turn a reply to an investor's data request into an update. ChatGPT and Claude draft from whatever you paste in. Cabal is built around drafts you write with your team, Foundersuite around updates with text, images, and KPIs, and Carta around updates that carry documents and a financial snapshot.

Is my data used to train AI models?

For Vectig: the narrative engine is conditioned on your prior updates, supplied as context — never used to train any model. For any other tool, ask the vendor and get the answer in writing.
