The investor-ready website: what VCs actually look at before a Series A

Your pitch deck gets less than two minutes of attention. According to DocSend's pitch deck research, average VC viewing time for seed decks dropped under two minutes for the first time in 2023. What happens in the hours after those two minutes? The partner Googles you. And they land on your website.

We've built websites for startups in the middle of fundraising, including Hylight during their Y Combinator batch (S23). Here is what we've learned about what investors actually look at, backed by the research that exists on how VCs make decisions.

Your website is part of due diligence, whether you like it or not

The numbers behind venture decision-making are public, and they should change how you think about your web presence. According to the Harvard study by Gompers, Gornall, Kaplan and Strebulaev, for each deal a VC firm closes, it evaluates an average of 101 opportunities. The average deal takes 83 days to close, and the average firm spends 118 hours on due diligence and calls 10 references.

At the top of that funnel, nobody spends 118 hours on you. They spend minutes. Your website is the cheapest filter a VC has: it answers three questions, do I understand it, do I believe them, is this moving — without a single email. Founders who treat their site as a formality are handing the filter a reason to say no.

And the first impression forms faster than you think: Stanford's Web Credibility Research found that 75% of users judge a company's credibility by its website design. Design is not decoration at this stage, it's a proxy for execution.

The five things VCs actually check on your website

1. Can they understand what you do in one scroll?

The single most common failure. If a generalist partner can't rephrase what you do after ten seconds on your homepage, the mental effort gets logged as risk. Your hero section should pass what we call the repeat test: a visitor should be able to explain your startup to someone else after one visit. Specific beats clever — "hydrogen airships for infrastructure inspection" beats "reinventing aerial intelligence".

2. The team page

Early-stage investing is team investing: in the same Harvard study, VCs ranked the management team as the most important factor in deal selection — ahead of business model, product, and market. Yet the team page is usually the least invested page on a startup website. Real photos, spelled-out backgrounds, publications, patents, previous exits: this is diligence material. Make it easy to verify you.

3. Proof, not adjectives

Investors scan for evidence: customer logos, pilot programs, key metrics, press coverage, grants won. One real number beats three superlatives. If your traction is confidential, show its shape ("3 paid pilots with European utilities") rather than hiding it entirely.

4. Momentum signals

A VC checking you out mid-raise will look for signs of life: a news section updated this quarter, open roles, a changelog, recent talks. A website frozen since incorporation whispers that the company might be too. Freshness is a signal you can control for the cost of a monthly update.

5. Technical credibility without jargon

Especially in deeptech, the website has to do something hard: convince a technical co-investor without losing the generalist partner. The startups that get this right layer their story, a plain-language value proposition up front, then architecture diagrams, 3D product visuals, and documentation for those who dig. That's the approach we detail on our deeptech web design page.

What we learned building a website during a YC batch

When Hylight came to us during Y Combinator S23, the brief was explicitly investor-driven: the site had to make hydrogen airships for pipeline inspection feel inevitable, not experimental.

Three choices mattered more than everything else:

• One sentence, one job: the hero went through more iterations than any other section — every word had to survive the "would a partner repeat this correctly" test.

• Show the machine: we built a custom 3D scene of the airship instead of stock aerial photos. Investors kept referencing it in calls — it made the product tangible before the first meeting.

• De-risk the team: founders' engineering backgrounds, the YC badge, and press coverage placed where a skimming reader can't miss them.

The same logic applied when we redesigned Kestrix's site ahead of their growth phase in London's climate tech market: make the technical data legible first, impressive second.

The pre-Series A website checklist

Run your website through this list before your raise. Each item is something a VC can check in under a minute:

• Value proposition readable and repeatable in under 10 seconds.

• Team page with real photos, verifiable backgrounds, and links (LinkedIn, Scholar, GitHub).

• Traction section with at least one concrete number, logo, or named pilot.

• Press & news updated within the last quarter.

• Technology explained in layers — plain language first, depth on demand.

• Social proof — accelerator badges, grants, partners, testimonials.

• Open roles visible (hiring = momentum).

• Fast, polished, mobile-clean — partners will open your site from their phone between meetings.

• A clear next step — a contact that reaches a founder, not a dead form.

• Consistency — same story on your site, deck, and LinkedIn. Discrepancies read as sloppiness.

When to invest in your website — and when not to

Honest answer: don't start a full redesign three weeks before your raise. A rushed rebuild mid-fundraise creates risk, not credibility. The right window is 2–4 months before you go out, enough time for a proper project (a complete site takes 4–6 weeks with us) and for the new story to settle into your deck, your site, and your talking points.

If the raise is imminent, do triage instead: fix the hero message, the team page, and the traction section. Those three pages carry most of the diligence weight.

Your technology deserves a website that works as hard as your deck. If you're preparing a raise and your site isn't ready for the scrutiny, talk to us, we've done this under batch-deadline pressure, and we know what investors need to see.
