The Website Builder That Walked Away From Half Its Customers
Founders Itai Sadan and Amir Glatt stopped chasing do-it-yourself small businesses and bet the company on the professionals who build websites for a living. Fourteen million sites later, the decision reads as deliberate.
Most startups spend their early years trying to add customers. Around 2014, Duda did something closer to the opposite. The company had launched a few years earlier as DudaMobile, a tool for turning clunky desktop sites into mobile-friendly ones, and it was selling to just about anyone with a website to fix. Then its co-founders looked at who was actually sticking around, paying more, and asking for harder features - and made a call that most founders find unnatural. They narrowed the audience on purpose.
The people Duda decided to build for were not small-business owners at all. They were the professionals those owners hire: web design agencies, freelancers, digital marketers, hosting companies and software platforms that need to spin up hundreds or thousands of sites without reinventing the plumbing each time. Everyone else - the classic do-it-yourself crowd that Wix and Squarespace fight over - was politely shown the door on the roadmap.
That is a strange sentence for a website company to say out loud. It is also the cleanest way to understand what Duda is. Founded in 2009 in Palo Alto by Itai Sadan (chief executive) and Amir Glatt (chief technology officer), the company runs a two-hub model that quietly powers a lot of the modern web - a go-to-market operation in California and an engineering center in Tel Aviv, with additional offices in Louisville, London and Florianopolis, Brazil.
01 / What it actually isSoftware you have used without knowing it
Duda is a business-to-business website platform. At its center is a drag-and-drop editor that produces responsive sites, wrapped in the machinery a professional needs to run many of them at once: a template library, dynamic pages, multilingual support, eCommerce, native booking and forms, SEO tooling, an app and widget store, client billing, granular team permissions and API access.
The feature that defines the company, though, is the one you cannot see. Duda is white-label by design. An agency can put its own logo and domain on the editor and dashboard, hand clients a simplified builder, and resell the whole thing as its own product. The end customer may never learn that the software underneath is called Duda. That invisibility is not a bug in the marketing - it is the pitch.

02 / Who it is forThe people who build sites for a living
Duda counts more than 450,000 businesses on the platform, and says roughly 14 million websites have been built with it, together drawing over 100 million visits a month. But the headcount that matters is smaller and more specific: the agencies, freelancers and platforms who log in daily. For them the pain is not making one beautiful page. It is managing two hundred client sites with different logins, billing cycles, approval chains and performance standards - and doing it without a full engineering team.
That is the gap Duda sells into. Client management, collaborative editing, white-label branding, permissions and an API turn a design tool into something closer to an operations system for a web shop. It is also why the company's largest revenue relationships are not individual designers but platforms - hosting and services companies such as 1&1 IONOS, Thryv, Hibu, Italiaonline and Brazil's UOL that embed Duda beneath their own brands.
03 / How it is differentThe third door past Wix and Squarespace
Ask the internet "Wix or Squarespace?" and you get a thousand comparison posts. Both are excellent at their job: helping one person build one site. Duda rarely wins that fight, and does not try to. Its argument is that the question itself is wrong for professionals. If you are building a single site for yourself, the consumer tools are cheaper and friendlier. If you are running an agency, the requirements change shape entirely - and white-label branding, multi-site management and client permissions become the whole game.

Duda reports a Core Web Vitals pass rate near 85% across sites it hosts. For an agency, fast pages are not vanity - they are the thing a client can measure, and the reason to keep paying.
04 / The AI turnBuilding websites by talking to them
If the first big bet was focus, the second is artificial intelligence - and here Duda has moved faster than its low profile suggests. At DudaCon 2025 the company rolled out what it calls a full-stack AI suite: Duda Copilot, a conversational assistant inside the platform; an AI Widget Builder that turns a plain-English description or a design into working widget code using Duda's own JavaScript API; and File-to-Site, which takes a client brief or copy document and drafts a complete website from it.
The most forward piece is a Model Context Protocol (MCP) server. It lets external AI assistants such as Claude and Cursor take real, authenticated actions inside a Duda account - add a client, publish a blog post, generate a collection - through natural language. Duda also became the first website platform to roll out llms.txt across every site it publishes, a machine-readable file that helps AI answer engines like ChatGPT understand a page. The company says about 45% of all new sites now use at least one AI feature.
That quote is really Duda's answer to the anxious question hanging over its own customers: if AI can generate a site in seconds, what is a web agency for? Sadan's framing is that the value was never the hours of dragging boxes around a screen. It was the judgment, and the outcome. Duda's job, on this view, is to hand the professional faster tools and let them charge for the result rather than the labor.
05 / The business, the moneySelling to the sellers
The model is straightforward B2B software-as-a-service. Duda sells tiered subscriptions, with higher plans unlocking white-label branding, more sites, team seats and API access, and a meaningful slice of revenue comes from platform and reseller deals where partners bill their own customers. Third-party estimates put annual revenue in the low tens of millions of dollars, though the company does not officially disclose it.
On the funding side, Duda has raised about $100 million in total. The headline round was a $50 million Series D in June 2021, led by Claridge IL alongside existing investors Susquehanna Growth Equity and Vintage Investment Partners, used to expand the platform and hire around 100 people. Notably, all of that went into a business that spends almost nothing acquiring consumers - the entire thesis is that professionals and platforms are underserved and will happily pay for better tools.
Itai Sadan and Amir Glatt start the company as DudaMobile, focused on mobile-friendly sites.

Duda is named Editors' Choice website builder, one of 20+ industry awards it has collected.
Total funding reaches $100M; the company funds roughly 100 new hires.

06 / Where it fitsA quiet layer of the web
Duda sits in a part of the market that consumers rarely see and professionals rarely leave. It is not trying to be the most famous name in website building - that race belongs to Wix and Squarespace, with Webflow and WordPress crowding the edges. It is trying to be the layer underneath a certain kind of business: the agency, the reseller, the platform that needs to produce good sites at volume and put its own name on them.
The bet made in 2014 - fewer customers, deeper ones - is the same bet the company is now extending into AI. Whether talking to a website through an assistant becomes normal or stays niche, Duda has already decided who it is building for. The scooter shop from its own marketing image will never know the software's name. For Duda, that has always been exactly the point.
