Design and development for AI startups AI products that feel human, clear and safe to buy.
Visinex designs and builds brands, websites and product interfaces for AI startups. In a market where new AI tools launch every day, we help you look like the one buyers can trust: a distinctive name and brand, a site that shows what the product really does, and an interface that also handles the moments the AI gets it wrong.

What AI founders ask us to solve.
Four questions AI founders bring to the intro call, and how we answer them.
Standing out from generic AI
When every product promises an AI assistant, a generic name and gradient disappear. For Kairos we created the name and a mark built from bars, so three AI sales products read as one family the market remembers.
Trust before the demo
Buyers in high-stakes markets need to trust you before they try you. Rondah’s AI receptionist answers every call for dental groups, so its brand had to feel as calm and dependable as the best front desk, and clear enough for the people who run multi-location groups.
From prototype to product
A prototype built in Lovable, Bolt or Cursor can impress in a pitch and break in real use. We scope one use case and build it properly in six to ten weeks, with auth, data, guardrails and analytics, and the code and data in your name.
A site ready for the round
Investors, candidates and customers all check your website before the first call. Solstice, an AI-native pharma agency, went into its $21M Series A with the brand and Framer site we built, and its team keeps building on the site themselves.

AI companies we designed for.
Working with us from the US or the UK.
Most projects run remotely, in English, with weekly reviews in your time zone. These are the practical answers founders abroad ask before the first call.
- Time zones
- London is one hour behind us, New York six and Los Angeles nine. We plan calls in your working hours, also when that is outside ours.
- Clients across the Atlantic
- We work with teams in New York and Los Angeles, and we designed the brand and product of Rondah, used by 300+ dental groups and practices across the US and Canada.
- Prices in dollars
- Prices on this site are in US dollars, excluding VAT. Your proposal states the currency, the payment terms and how VAT applies to your country.
- Contract and ownership
- Our terms are governed by Dutch law. Source files, code and accounts are in your name from day one, so nothing is ever stuck with us.
Every review comes from a client we designed or built for. Read all client reviews or see the work.

We pick the model per use case, often Claude or OpenAI, and build the product so you can switch models later without a rebuild. Product first, model second: we start from the user problem, then choose the model, data and guardrails. The product itself often runs on Next.js and Supabase.
Most AI MVPs take six to ten weeks from kickoff to a version real users can try. Week one defines one use case, the users and one success metric; real users and analytics guide the next version from week nine. See AI MVP development.
Yes. If you started in Lovable, Bolt or Cursor, we review the code, fix the foundations and make it ready for real users. Most AI prototypes impress in a demo and break in real use, so we add the auth, data and guardrails a real product needs to hold up.
Every project gets one fixed price after a short intro call. Brand identities start from $6,500, websites from $5,500 and product design from $6,595, all excluding VAT. An AI MVP is priced on the use case, the integrations and the data work. See pricing.
Only if the sources they read agree. We check how ChatGPT, Perplexity, Gemini and Google’s AI Overviews describe your company, then fix what’s missing with structured data, clear pages and consistent profiles. See AI visibility.
