tethys-robotics.com Domain Fails to Resolve — Real Site Is tethys-robotics.ch
Score
5
Severity
Critical
Finding
The submitted URL https://www.tethys-robotics.com fails with a permissions/DNS error. The company's actual website is tethys-robotics.ch — a Swiss ccTLD domain. Press coverage (EU-Startups, Startupticker, Robotics & Automation News, TFN, Startbase) universally links to tethys-robotics.ch. The .com domain is unmapped, unredirected, or not registered. Any journalist, investor, offshore wind operator, or navy contractor who types tethys-robotics.com — the natural first-guess domain for a company called 'Tethys Robotics' — hits a dead end.
Recommendation
Register tethys-robotics.com (if not already owned) and configure a 301 redirect to tethys-robotics.ch immediately. At €3.5M pre-seed funded, the domain acquisition cost is negligible. Also consider whether to migrate to a .com primary domain (more internationally credible for B2B sales in offshore wind, oil & gas, and defense sectors) with tethys-robotics.ch redirecting, given the company's stated plan to 'enter the US and Asia-Pacific markets.'

Tethys ONE Specifications (35 kg, 300 m depth, 10 min deploy, 2.5 kt current) Not in Homepage Hero
Score
22
Severity
High
Finding
The Tethys ONE's key specifications — 35 kg weight, 300 m depth rating, 10-minute deployment, and 2.5-knot current tolerance — are the primary differentiation metrics for an underwater drone competing against conventional ROVs and dive teams. These specs appear in press articles (Startupticker, TFN, Startbase) but their prominence on the homepage is unclear. For offshore energy procurement teams, these specs are the first qualification criteria.
Recommendation
Add a specifications callout block to the homepage hero or immediately below it: 'Tethys ONE: 35 kg · 300 m depth · 10-min deployment · 2.5 kt current tolerance · dual ROV/AUV mode.' This block answers the qualification questions immediately and differentiates Tethys ONE from larger, slower-deploying conventional ROV systems that require vessels and dive teams.

Finding
The homepage lists multiple use cases with equal prominence: hydropower inspection, offshore wind, oil & gas, search and rescue, and unexploded ordnance (UXO) clearance. These are very different markets with different procurement processes, decision-makers, and sales cycles. A site trying to serve all audiences simultaneously with equal weighting ends up speaking persuasively to none.
Recommendation
Prioritize the top two use cases by revenue opportunity and current traction: (a) offshore wind (the company has the SeaRenergy partnership and the fastest-growing market); (b) UXO clearance (unique differentiator, cited in press as Swiss Army / SDRC collaboration). Lead with the highest-value use case and make the others secondary in the page hierarchy. Consider dedicated landing pages for each sector.

The Tethys Robotics press coverage mentions that the company already works with the Swiss Army and the Swiss Drone and Robotics Centre (SDRC) — specifically for UXO (unexploded ordnance) disposal missions. This is an extraordinary credibility signal for a pre-seed company. Military / defense procurement is the strongest possible social proof signal for any robotics company in the autonomous underwater domain. It is mentioned only in press articles, not on the homepage.
Recommendation

The Swiss Army reference in particular should be prominently featured — it signals that Tethys ONE has passed rigorous military qualification requirements and is trusted for safety-critical missions. This is a differentiation no competitor can easily replicate.
