People with a stake

Advisor and Investor Endorsements for Startups

An early startup often has more praise from its angels, advisors and board than from customers. Those quotes can be real and generous, but the people giving them own a piece of the outcome. Under the FTC Endorsement Guides read for this page, that kind of connection usually has to be stated where the quote appears. Work through the checklist before a backer’s words go on your site.

  • Spots equity, advisory shares and fees
  • Separates “backs the team” from “uses the product”
  • Disclosure wording placed beside the quote

Checklist

Before a backer’s quote goes on the site

Tick each line for one quote. Lines with a source summarise the FTC text they cite. This is a summary, not legal advice.

The problem, solved

Managing backer quotes in StoryProof

  • Problem 1

    Our best quotes come from our investors

    An angel who is also a heavy user says something perfect, and it is tempting to post it without the word “investor” next to it.

  • Problem 2

    Nobody remembers who holds equity

    A year later, a new hire adds an advisor’s quote to a landing page with no idea they hold shares.

  • Problem 3

    Backer praise is drowning out customers

    Three investor quotes on the homepage make the startup look like it has no users of its own.

  • Problem 4

    We wrote the quote and they nodded

    A founder drafting a line for an advisor to approve produces your words in their name, not their opinion.

  • Problem 5

    We never asked actual customers

    Backers are easy to ask, so requests to the people paying you never get sent.

Who is speaking, and how to show it

A summary of the FTC text read for this page, for US businesses. Your counsel may draw the lines differently.

BackerProduct testimonial?How to present it
Angel who also uses the product dailyYes, with disclosure“Investor and customer” beside the quote
Advisor paid in equity, never used itNoA statement about the team, labelled with the advisory role, off product pages
Board member from an investing fundRarelyName the fund and the board seat; better on an about page

Fund partner quoted in press coverageNoLink to the article rather than lifting the quote

In StoryProof

From backer quotes to customer proof

  1. 1

    Collect in their own words

    Send backers who use the product the collection link rather than a drafted line.

  2. 2

    Label and tag before approving

    Write the stake into the attribution and tag the testimonial with it, then approve.

  3. 3

    Keep them off product pages

    Build a separate widget for backer quotes on the company page; product page widgets show customers only.

  4. 4

    Ask every paying customer

    Add customers as contacts and send requests as soon as each has had real use of the product.

What happens next: Revisit backer quotes after each funding round, when stakes and roles change and new disclosures may be needed.

Before you start

Read before relying on this

What this does not cover, and what to check on your side. Better to know now than after launch.

  1. 01

    Not legal advice

    This summarises the FTC Endorsement Guides as read on the date shown, for the US. Securities rules on mentioning investors are a separate subject this page does not cover.

  2. 02

    Investors are not named in the FAQ

    The FTC FAQ read here does not discuss investors directly. The ownership point comes from an example in 16 CFR 255.5 about an endorser who owns part of a company.

  3. 03

    No automatic disclosure label

    StoryProof does not detect or add a backer’s stake. You write it into the attribution yourself.

  4. 04

    Logos of funds are a different claim

    A “backed by” row of fund logos states a fact about funding, not an opinion of the product. Check it with each fund before showing it.

FAQ

Questions people ask

Short answers to what usually comes up next.

Can a startup use quotes from its investors on its website?

Yes, if the investment is disclosed beside the quote and the words are the investor’s own honest view. If they have not used the product, present it as a view of the company, not a product testimonial.

Does an advisor with a small equity grant need to be disclosed?

Under 16 CFR 255.5, a connection that could affect how readers weigh an endorsement, and that they would not expect, should be disclosed. Readers rarely expect an advisor to hold equity, so state it.

What wording should the disclosure use?

Plain and short, beside the name: “Investor in Acme”, “Advisor to Acme, holds equity” or “Board member, Acme”.

Is a board member’s praise better than nothing?

On an about or company page it can show who stands behind you. On a product page it can read as filler, so replace it with customer proof as soon as you have some.

Still have a question? Ask the StoryProof team or book a demo.
