The verdict in three sentences
A 14-person deeptech startup preparing a Series A should plan EUR 8,000 to 15,000 (about USD 8,700 to 16,300) for a website that is credible to funds, delivered in 6 to 8 weeks. The site will not raise money for you, but a fund analyst checks it before the first meeting and uses it to judge how clear your value proposition is. The two items that make the difference are plain-language explanation of the technology and native-quality English, not 3D animation.
Cost of a pre-raise deeptech website in 2026
2026 orders of magnitude for a lab spin-off startup.
| Item | 2026 range (excl. tax) | What you get |
|---|---|---|
| Core (8 to 12 pages, custom design) | EUR 8,000 to 15,000 | Home, technology, applications, team, careers, contact |
| Technical diagrams and illustrations | + EUR 1,500 to 3,000 | 4 to 6 visuals explaining the physical principle |
| Press area | + EUR 800 | Media kit, releases, logos, HD photos |
| Light data room (protected link access) | + EUR 2,000 | Deck, patent summary, roadmap, with view tracking |
| Native English version | + EUR 1,500 to 2,500 | Translation reviewed by a native speaker, not machine output alone |
| Careers page with ATS (Lever, Greenhouse) | + EUR 600 | Essential if the round funds 10 hires |
| Maintenance | EUR 80 to 120 per month | Updates, security, small changes |
A typical project, core at EUR 10,000, illustrations, press, data room and English, comes to about EUR 16,500, or 0.27% of a EUR 6 million round.
The content investors actually read
A deeptech fund associate spends 3 to 5 minutes on the site on average before a first call. They look for precise answers.
| Investor question | Page that answers it | Common mistake |
|---|---|---|
| What problem, for which market? | Home, in one sentence | Opening with the technology |
| Why is your technology better? | Technology, with a quantified comparison | Thesis jargon with no orders of magnitude |
| What intellectual property? | Technology or data room | No mention of patents |
| Who are the first customers or pilots? | Applications, logos | "We work with large groups" with no names |
| Can the team industrialise? | Team, industry profiles | Only PhDs are shown |
| What timeline? | Simplified public roadmap | Unrealistic dates that backfire in diligence |
The explanation rule that works: a headline a generalist understands, a paragraph for the engineer, a link to the paper for the scientist.
Funding the site: grants and timeline
Grants rarely fund "a website" as such, but several schemes cover part of the spend when it belongs to an innovation or commercial development programme. In France, Bpifrance can include communication costs in a broader innovation project; in Singapore, Enterprise Singapore schemes play a similar role for market development. Check eligibility before signing the quote, since spend committed before the application is often excluded.
| Step | Week | Deliverable |
|---|---|---|
| Messaging and positioning workshop | W1 | One-sentence value proposition approved |
| Mockups and illustrations | W2 to W3 | Key pages approved |
| Development | W3 to W6 | Site in testing |
| English copy and review | W5 to W6 | Native EN version |
| Data room and launch | W7 to W8 | Public site plus investor access |
Ideally, the site is live 4 weeks before the first meetings of the fundraising roadshow.

Mini case study
Wei Ling, CEO of a 14-person photonic sensor startup in Singapore, is preparing a EUR 6 million Series A. Her current site dates from incorporation and is pure jargon. She invests EUR 16,500 in a redesign, including EUR 2,000 for the data room. During the roadshow, 38 funds open the data room, letting her prioritise follow-ups with the 11 funds that opened the patent summary. If that prioritisation saves 3 weeks on the fundraising timeline, at a burn rate of EUR 120,000 a month, the gain is about EUR 90,000 of preserved cash, more than 5 times the cost of the site.
FAQ
Should we redo the site before or after the round?
Before, ideally 4 to 6 weeks ahead of the first meetings. After the round, plan a second phase focused on hiring and customers, often EUR 4,000 to 6,000.
Does a data room on the site replace a professional data room?
No. The light data room at EUR 2,000 serves as a first filter: deck, patent summary, roadmap. Due diligence then happens on a dedicated tool such as Datasite or a secured drive.
Is native English essential?
Yes for a deeptech Series A: most specialised funds work in English. Allow EUR 1,500 to 2,500 for a reviewed native translation.
Can we show our patents safely?
Published patents are public, so you can cite their numbers. Unpublished applications and know-how stay in the data room with tracked access.
How long does delivery take?
Between 6 and 8 weeks, the bottleneck usually being approval of technical copy by the science team.
Let's scope your project. A pre-raise deeptech website can be scoped in one workshop: indicative budget EUR 10,000 to 17,000, delivery in 6 to 8 weeks with English version. Detailed quote within 48 h. WhatsApp +221 77 596 93 33.
