Replit Opens Its London Office Inside an AI Crowd

Replit opened its first office outside the United States in London on September 7, with Mayor Sadiq Khan at the ribbon. The San Francisco coding startup has about 20 people on the ground in King’s Cross and says that number could reach 100 in early 2027, if AI adoption holds.

Amjad Masad, Replit’s co-founder and chief executive, used the launch to needle Silicon Valley as a “monoculture.” He then put the company in the one London district now compared with San Francisco and Beijing.

The company’s own opening of its first international office was staged as a European hub, not a listening post. Replit said it has hired in London across sales, support and engineering in a few weeks, and that it will use the site to serve small businesses and enterprises already on the platform.

Masad was warmer about the city than about the industry that made him. He still credits the Valley. He also described a place where you never get a night off from tech.

I love San Francisco. Silicon Valley is obviously a place that has given me a lot. But there is like one major downside, which is it’s a bit of a monoculture. Everyone speaks the same language. You can never escape tech, it’s endless. When I come to London, I meet artists, I meet people in finance, I meet filmmakers. It’s really amazing how diverse the community is here.

He added that mixed teams throw off mixed ideas. The room that showed up for the opening, though, looked a lot like a sales kickoff: operators and small-business owners, the people Replit actually bills. Artists and filmmakers were the contrast in the speech, not the guest list.

Replit marked the day with Khan’s team, His Majesty’s Government, The Lord Mayor’s Appeal and London & Partners.

The Neighbourhood Already Speaks One Language

King’s Cross sells itself as more than offices. The Knowledge Quarter, the membership group around the stations, calls the patch Europe’s premier innovation district, a one-mile mix of labs, libraries, universities and companies. Khan went further at the launch, saying Europe’s cultural, technology, financial and political capitals all sit in London, a “massive, massive advantage” for anyone starting, scaling or expanding AI.

The street-level version is narrower. Google DeepMind moved in during 2016, after Google bought the lab, and the rest of the industry followed the talent. OpenAI, Anthropic, Meta, Isomorphic Labs, Wayve and Synthesia now sit in the same few blocks. UCL is around the corner. Founders talk about the neighbourhood the way people in South Park talk about Sand Hill Road.

Knight Frank, the letting agent, has the receipts. Chris Dunn, a commercial insight associate there, said prime rents in King’s Cross have risen 18% over the past three years on leases of at least 10,000 square feet, and that vacancy for ordinary offices is 0.9%. AI-related firms have leased more than 1 million square feet of London space since the start of June 2026, per the same firm. Dealroom counts about 3,600 AI startups in the city.

WHO SHARES THE POSTCODE

Pay is starting to look familiar too. When Anthropic advertised a machine-learning research engineer in London, the range ran from £260,000 to £630,000, against a local average near £102,000 for the same title. Homegrown startups in the same cafes now have to raise larger rounds just to keep people.

A 20-Person Team Against 800-Seat Neighbours

Replit is not arriving as a peer of those labs. It is arriving as a tools vendor that wants European companies to build software on its agents, and as a recruiter that has so far staffed a beachhead. Masad’s 100-person figure is a ceiling with a condition attached, not a headcount the company has funded in public.

THE LONDON HEADCOUNT

• On the ground: About 20 staff, hired in a few weeks across sales, support and engineering.
• The ceiling: As many as 100 people in early 2027, Masad said, depending on AI adoption.
• The global line: Replit said it expects to double company-wide headcount and investment in the year after the opening.
• The neighbour: Anthropic’s new floorplate has space for 800, four times its current London roster of about 200.

Those two “double” and “100” lines are easy to mash together and should not be. Twenty to 100 is a fivefold jump in one city. The doubling in the press release is a worldwide staffing and spend target. Tokyo and New York are already named as later offices, which means London is one node in a map, not a one-way bet on Britain.

Kanishka Narayan, the newly appointed UK Minister for AI, called Replit the kind of fast-growing firm the country wants to pull in. For City Hall, a ribbon with a $9 billion American company is cheaper than a semiconductor plant and photographs better. For Replit, the mayor’s presence is a distribution channel into government, universities and the large employers already on its customer list.

What Masad Wants London to Buy

Replit started in 2016 on the idea that someone should be able to ship an app without learning to code. The current product is an agent that writes, hosts and deploys software from natural language, with design, databases, security and enterprise controls in one environment. Agent 4, shipped with the spring funding round, is billed as 10 times faster than Agent 3 and can run several agents in parallel on a shared canvas.

The company now claims more than 60 million users worldwide, with people inside 85% of the Fortune 500. In March it raised $400 million at a $9 billion valuation, a threefold jump in six months, and said it was on track for $1 billion in run-rate revenue by the end of 2026. Georgian led the round. Accenture Ventures, Databricks Ventures, Okta Ventures, Tether, Y Combinator, Coatue and a16z came in, as did Shaquille O’Neal and Jared Leto.

That money was always earmarked for expansion in Europe, Asia and the Middle East, plus more compute. London is the first brick. India is already Replit’s second-largest market. The harder European job is getting regulated industries to leave finished tools on Replit instead of rebuilding them in-house once a prototype works.

WHO IS ALREADY ON THE PLATFORM

• In Europe: PricewaterhouseCoopers, Ernst & Young, Mercedes-Benz Group, TrustPilot and Hg.
• In the United States: Accenture, Visa, Zillow, Atlassian, Adobe and Databricks, among others named in the London release.
• The pitch to those teams: Non-engineers spin up internal apps while the company keeps governance, tenancy and deployment in one stack.

Masad also used the London stage for a policy line that Silicon Valley usually phrases as a warning about everyone else. “One of the first things is maintaining a level playing field,” he said. “We don’t want to see what happened in the last generation of platforms happen again, meaning we don’t want just two or three companies controlling all of AI. We want open source AI, we want accessible AI.”

He is saying that in a district where the two most valuable closed model labs have just taken the biggest new leases. Replit also collaborates with OpenAI on a free tier, and it is throwing a London party with the same company. The open-source sentence and the guest list do not cancel each other. They sit in the same week.

Young Londoners Get a Four-Week Coding Pilot

The civic overlay is a course, not a campus. Replit is partnering with The Lord Mayor’s Appeal, the City of London charity that focuses on young people not in education, employment or training, on a four-week pilot for 100 young Londoners from disadvantaged and under-represented backgrounds. The syllabus is “vibe coding,” the company’s phrase in its own release, pitched as a way into jobs.

The charity’s own plan for 2026 to 2028 is to raise over £4 million and reach more than 15,000 Londoners, using the Lord Mayor’s convening power with firms and livery companies. The Replit course is a small, time-boxed slice of that. It is also a neat answer to the political question hanging over every AI office opening in the capital: who in the city actually gets to use the tools.

The labour-market backdrop is not pretty. A government interim report on young people and work put the UK youth NEET rate of 12.8% for 16- to 24-year-olds at the end of 2025, against a 9% EU average for 15- to 24-year-olds. Masad’s written line on the partnership was that AI will transform work, so far more people have to be able to use it to build businesses and find new jobs.

On X he went further, saying he liked Khan’s self-description as an “AI realist,” clear-eyed about disruption and still willing to put tools in people’s hands. That is also how City Hall needs the story to sound. A four-week cohort of 100 is not an employment programme for a city. It is a proof of presence, and it will be judged on whether those 100 people get work, not on whether they can prompt an agent to make a landing page.

Tokyo and New York Are Already on the Map

Masad told the launch audience that offices in Tokyo and New York are planned on top of London. The March funding post had already named Europe, Asia and the Middle East as the spend zones. Read that way, King’s Cross is the first flag, not the destination.

THE ROAD TO THE RIBBON

1. 2016: Replit is founded in San Francisco on the bet that people can build apps without learning to code.
2. March 11, 2026: The company raises $400 million at a $9 billion valuation, a threefold jump in six months, and ships Agent 4.
3. September 7, 2026: It opens the first office outside the United States, in King’s Cross, with Sadiq Khan at the ceremony.
4. September 10, 2026: It hosts a London launch night with OpenAI and a fireside chat with Paul Graham.

The adoption hedge on the 100 jobs is the most honest sentence in the packet. Replit’s growth since it launched an agent has been steep enough to reprice the company three times over, and steep enough that a slowdown in how fast companies trust those agents would show up first in a new office’s hiring plan. Sales and support seats in London only make sense if European firms keep putting production apps on the stack, rather than using it as a toy for hack days.

The other constraint is talent math. A 20-person team can be hired on startup wages plus visa sponsorship. A 100-person team in the same postcode as Anthropic’s 800-seat office will walk into the same salary war that already forced local founders to raise more. Diversity of passports is easy to find in London. Diversity of compensation bands is not, not on this stretch of canal.

Paul Graham and OpenAI Share Thursday Night

On September 10, Replit and OpenAI host drinks, music and a fireside chat with Paul Graham, the Y Combinator co-founder who has been Masad’s most public champion. RSVP runs through Replit’s own launch page. Google Cloud is also running a hands-on build session at the new office so non-technical teams can try live apps on the product.

Khan’s written welcome treated the lease as a vote of confidence in the London Growth plan and in AI used “responsibly.”

I’m delighted to welcome Replit to London as they open their first international office in the King’s Cross Knowledge Quarter. As a world-leading city for technology, education and innovation, London has a wealth of talent, a diverse skills base and is already home to an array of leading AI companies.

Sadiq Khan, Mayor of London, in Replit’s London opening statement

He is right that the city is already home to those companies. That is the part Masad’s monoculture riff leaves out. The artists and filmmakers are in Hackney and Soho. The office Replit opened is in the square mile where everyone, once again, speaks the same language, and where the Thursday night guest of honour is the same lab that sits at the centre of that language in San Francisco.

Whether the London roster ever gets from 20 to 100 will depend on how fast European firms let agents ship code. The postcode is already decided, and it looks like home.
