Summarize with AI
Yes, you should put investor logos on your website, but not on the homepage hero. Investor logos persuade candidates, journalists and other investors. They do little for buyers, and placed above your customer proof they tell a buyer the company is selling to the people who already paid, so put them on the about page and the careers page instead.
This matters because the homepage is the page a buyer reads in about four seconds, and those seconds decide what kind of company you are. You know who backed you and why that means you will be around. The stranger from a plant in Ohio does not, and a row of fund logos under your headline answers a question she was not asking.
The Backed by row under the Book a demo button
Here is an example, invented for this post. A seed-stage AI startup drafts air permit compliance reports for manufacturing plants. It reads meter data, stack test results and maintenance logs, then writes the quarterly report a plant sends to its state regulator. The hero reads Your air permit reports, drafted from plant data. One button says Book a demo.
Directly under that button sits a grey label, Backed by. Next to it is the orange Y Combinator square with the batch code under it, then the wordmarks of two seed funds. Then three round headshots of angels, each with a caption: Ex-founder, logistics AI. Partner, climate fund. Former VP Product at a large cloud company. The row is the second thing on the page and the first piece of proof.
Below it comes a grid of six feature cards, then Why we started, with a photo of the founders at a demo day. The only customer appears in the fourth section: one line from the EHS manager at a mid-sized adhesives plant, company named. A visitor who stops after the first screen never reaches it.
Who actually reads investor logos as proof
Investor logos prove one thing: someone with money looked at this company and said yes. The question is who needs that.
Candidates need it most. A senior engineer thinking about joining is betting a few years of her career on whether the company survives the next round. Known funds and named angels are evidence that other people did the checking. For her, the Backed by row is one of the most useful things you can show.
Journalists and other investors use it as a shortcut. A reporter checks who led the round. A Series A partner already has your cap table from the deck.
The buyer is the odd one out. The person in the example who books the demo is the Director of Environmental, Health and Safety at a plastics maker with three plants. She signs her name under every report that goes to the regulator, and a late or wrong one is her problem. Her first question is whether a plant like hers has used this and whether the vendor will still be here when the next permit renews. A Y Combinator square answers the second question badly. It says the company is new. Fund logos say it has investors who expect fast growth, and fast growth sometimes means a change of direction. Nothing in the row says a plant has ever trusted it.
What the founder sees, and what the demo form shows
The founder in this example put the row there for a reason. It worked. Two of the last three engineers he hired mentioned one of the angels in their first interview. His deck closes on an investor slide, and the meetings where he showed it went well. So the website follows the order of the deck, and the investor row moved up because it was the strongest thing he had.
The demo form tells a different story, if he reads the job title field. Over a month, the requests come from a software engineer, two students, a recruiter, an associate at a fund and one plant manager. On the call with that plant manager, the first question was how long the company had been around. Product questions came after. He now sends buyers a two-page PDF before the call, because it opens with the customer quote and the page does not.
He knows which proof matters to which person. The page shows it all to everyone in one order, set by the audience he talks to most, which is investors.
Where each kind of logo belongs
Most advice treats investor logos as general social proof: more names, higher up, more trust. That is wrong for any company that sells to people outside the startup world. Proof only works when it answers the reader's doubt, so the placement should follow the reader.
- Homepage hero: customer proof only. One named customer that looks like your buyer, or one result she can check. If you have none yet, say what the product does in plain words and show a real screen. Do not fill the space with backers.
- Homepage footer: one plain text line is fine, such as Backed by Y Combinator and two seed funds, with a link to the about page. Small, honest, and out of the buyer's first four seconds.
- About page: the full row. Fund names, angels who agreed to be listed, and one sentence on what each one brings beyond money. This is where journalists and investors look first.
- Careers page: high on the page, near the line about why to join. Candidates read this page to judge risk, and backers are the answer they want. Add when the round closed, because candidates ask.
The one exception is a company whose buyers are startups. A dev tool sold to seed-stage engineering teams can put a Y Combinator badge high, because its buyers read it as a peer signal and many of them came through the same programs. If most of your buyers have a procurement form, the exception does not apply to you.
Why the YC badge is a special case
A YC badge carries more meaning than a fund logo, and that cuts both ways. Inside the startup world it is one of the most recognised marks there is. Outside it, a buyer who knows the name reads it as an early company, and the batch code tells her how early to within a few months.
That is not a reason to hide it. It is a reason to put it where knowing your age helps the reader. A candidate wants a program with a strong network. A buyer at a regulated plant wants a vendor that will not disappear. Same mark, opposite readings, so it belongs on the pages built for the first reader.
Our post on how to make an AI startup look like a YC company covers the look. Placement is the narrower decision, and the look does not survive putting the wrong proof first.
Angels, advisors and when to cut them
Angel headshots are the weakest part of most Backed by rows. A buyer does not know the faces, and the captions describe past jobs in other industries. Three strangers in circles read as filler, the same way a logo strip of unknown names does.
Use one test for every angel and advisor on the site: would a stranger in your buyer's job recognise this name, or care about what this person did? In the example, an angel who ran environmental compliance at a large chemical company passes the test, and she belongs on the homepage as domain proof, written as expertise rather than as money. The ex-founder of a logistics AI company does not pass it. Move him to the about page, where his name helps with the next raise and the next hire.
Cut advisors who have gone quiet, and anyone who has not agreed to be listed. The same consent rule applies to backers as to customers, which our post on customer logos and permission sets out.
What the wrong order costs before the next round
The investors on your homepage already wrote their checks. The buyers below them decide whether the next one gets written. Seed rounds for AI startups are priced at valuations roughly 42 percent above non-AI peers, and only revenue from buyers closes that gap. For the next round, the Series A bar for AI startups sits around 3.5 million in ARR, up from roughly one million three years earlier (Carta, Q1 2026).
Every buyer who arrives was paid for, in ads, outreach or the founder's own hours. A first screen that leads with backers pushes the proof she needed below the fold. The cost never shows up as an error. It shows up as a demo form full of the wrong job titles.
The careful version is visible on the site we built for Chariot, a frontier AI lab. Its backing is unusual: it was selected by the Government of India and the IndiaAI Mission to build foundational models. The hero says that in one sentence of text, because it tells a reader what the lab was chosen to do. There is no row of backer logos. The researcher credentials, from DeepMind, Meta AI Research, Stanford and IIT, sit in the About section, and the proof further down is the work itself: demos and benchmarks.
A fix you can ship this week
- Open your demo form or contact list from the last month and sort it by job title. Count how many look like your buyer. That number tells you who the homepage is reaching.
- Take the Backed by row out of the first screen. Put one named customer, or one checkable result, in the space it leaves.
- Add a single text line to the footer that names your lead backers and links to the about page.
- Build the full row on the about page, with one sentence per backer, and repeat it near the top of the careers page with the date the round closed.
- Run the angel test. Keep on the homepage only the names your buyer would recognise for their work in her industry. Move the rest.
- Send the new homepage to one person who does your buyer's job and ask what kind of company this is. Write down the first sentence of the answer.
This is an afternoon of moving sections, not a redesign. If investors matter this quarter too, what investors look at on your website covers the pages they open. If you would rather hand the job to a studio, our ranking of website design agencies for YC-backed AI startups compares the options on public evidence.
Studio Maydit is a web and product design studio for AI founders in the US, UK and Europe. After a raise, the website question is which reader each page serves, and whether the first screen tells a buyer the size of company you have become rather than the size of the round you closed. We work on a fixed scope of three to four weeks, or on a monthly retainer with no long lock-in. If your homepage is still built in the order of your deck, book a 30-minute call with us and we will tell you what to move first.
