Some of the biggest names of Estonia’s tech scene are backing Lightyear, a startup looking to become Europe’s answer to commission-free trading pioneer Robinhood.
Based in London, Lightyear develops an app that lets users invest in a range of over 5,000 stocks, exchange-traded funds and money market funds. It was founded by two former Wise employees, Martin Sokk and Mihkel Aamer, in 2021.
The company is set to announce later on Thursday that it has raised $23 million in a new round of funding led by NordicNinja, a Japanese-backed venture capital fund based in Europe. Estonian tech entrepreneur Markus Villig, who co-founded ride-hailing unicorn Bolt has also invested.
Lightyear CEO Sokk told CNBC that the firm didn’t necessarily need to raise more cash for the business but chose to do so because of the caliber of investors involved.
“People like Markus have been building massive companies in many, many markets, and this is something that’s really exciting for us because it’s so hard to go into all the markets and understand their local dynamics and what people need,” he said.
Lightyear currently operates in 25 countries. However, with help from angel investors like Bolt’s Villig, the firm will be able to launch in another five markets “pretty quickly,” Sokk said.
Villig told CNBC that it can be “challenging to scale a business across multiple countries in a heavily regulated sector,” adding that Europe’s less developed retail investing market provides ample opportunities for disruption.
Other Estonian angel investors who have previously backed Lightyear also participated in the funding round, including Wise co-founder Taavet Hinrikus, Checkout.com’s formerChief Technology Officer Ott Kaukver and Skype founding engineer Jaan Tallinn.
Estonia is widely considered a prominent tech hub in Europe. The country is home to the highest number of unicorns per capita in Europe, according to the Estonian Investment Agency. Meanwhile, Estonia’s e-residency scheme has also enabled foreigners to become digital residents and launch their companies in the country.
The new round values five-year-old Lightyear at between $200 million and $300 million, significantly higher than its valuation in 2022 when it raised $25 million, according to two people familiar with the matter who preferred to remain anonymous as the information has not been made public.
Pushing into AI, crypto
Alongside the additional funding, Lightyear is also launching new artificial intelligence features. AI has been a hot area of investment for startups following the explosive popularity of generative AI services like OpenAI’s ChatGPT.
One of the features, called “Why Did It Move,” allows users to select a point in time on a stock chart and see what happened that day to cause a jump or fall in a company’s share price. The firm is also using AI to provide “bull” and “bear” theses on stocks as well as short updates on assets in their own portfolios.
“In the end, you’re going to have two models” when it comes to investing, according to Sokk: “Self-driving money,” where you ask an AI to achieve certain investment goals, and a “manual gearbox” approach of figuring out different strategies and approaches on your own.
Still, the market for online investment products is heavily competitive. Lightyear faces some hefty competition from both incumbent brokerage services as well as more modern tech players such as Robinhood, Revolut and Trade Republic.
However, Sokk insists Lightyear is building a differentiated enough product to stand out from the crowd. While competitors like Robinhood profit from offering risky products like crypto and margin trading, Lightyear is focused on serving long-term investors, he told CNBC.
To that end, Sokk said Lightyear is planning on rolling out a crypto product of its own in two months’ time — one that’s “more focused on a long-term view.”

AMD CEO Lisa Su said on Tuesday that the company’s overall revenue growth would expand to about 35% per year over the next three to five years, driven by “insatiable” demand for artificial intelligence chips.
Su said that much of that would be captured by the company’s AI data center business, which it expects to grow at about 80% per year over the same time period, on track to hit tens of billions of dollars of sales by 2027.
“This is what we see as our potential given the customer traction, both with the announced customers, as well as customers that are currently working very closely with us,” Su told analysts.
Ultimately, Su said that AMD could be able to achieve “double-digit” share in the data center AI chip market over the next three to five years.
AMD shares fell 3% in extended trading.
The AI chip market is currently dominated by Nvidia, which has over 90% of the market share, according to some estimates, and which has given the company a market cap of over $4.6 trillion, versus AMD’s roughly $387 billion valuation.
AMD is holding its first financial analyst day since 2022, as the company has found itself at the center of a boom in data center spending for AI.
While companies are spending hundreds of billions of dollars in total on graphics processing unit (GPU) chips to build and power artificial intelligence applications like OpenAI’s ChatGPT, they are also looking for alternatives to increase capacity and control costs. AMD is the only other major developer of GPUs aside from Nvidia.
In October, AMD announced a partnership with OpenAI in which it would sell the AI startup billions of dollars in its Instinct AI chips over multiple years, starting with enough chips in 2026 to use 1 gigawatt of power.
As part of the deal, OpenAI could end up taking a 10% stake in the chipmaker. Su also highlighted long-term deals with Oracle and Meta on Tuesday.
AMD shares have nearly doubled so far in 2025.

OpenAI is also helping AMD set up its next-generation systems based around its Instinct MI400X AI chips, which ship next year.
AMD has said that its chips will be able to be assembled into a “rack-scale” system where 72 of its chips work together as one, which is essential for running the largest AI models.
If AMD succeeds at its rack, it will catch up with Nvidia’s AI chips, which have been offered in rack-scale systems for three product generations.
Su said that the company now sees the total market for AI data center parts and systems hitting $1 trillion per year in 2030, representing 40% annual growth per year. AMD reported $5 billion in AI chip sales in its fiscal 2024.
That’s up from the company’s previous forecast of a $500 billion market in 2028 for AI chips. But the updated AMD figure also includes central processors (CPU), an important kind of chip that sits at the heart of a computer, but isn’t a pure AI accelerator like the GPUs made by Nvidia and AMD.
AMD’s Epyc CPUs are still the company’s most important product by sales. It primarily competes with Intel and some smaller Arm-based processors in the CPU market. AMD also makes chips for game consoles, networking parts, and other devices.
On Tuesday, although AMD focused much of its focus on its growing AI business, it told shareholders that its older businesses were growing too.
“The other message that we want to leave you with today is every other part of our business is firing on all cylinders, and that’s actually a very nice place to be,” Su said.
CoreWeave shares sank 13% on Tuesday after CEO Mike Intrator addressed delays at a third-party data center developer that hit full-year guidance in its latest earnings report.
“Quite frankly, every single part of this quarter went exactly as we planned, except for one delay at a singular data center,” Intrator told CNBC’s “Squawk on the Street” on Tuesday.
He then clarified that a “singular data center provider” is more accurate.
“Some people might think it’s one complex, but when I go over the numbers, we’re talking about multiple places,” CNBC’s Jim Cramer said. “And it just so happens that the places are all connected to an outfit called Core Scientific that you tried to buy.”
Cramer noted delays at complexes in Texas, Oklahoma and North Carolina.
Intrator said the companies have been working together on infrastructure for a long time a would continue work to bring it online. He did not directly confirm that Core Scientific is the third-party provider.
CoreWeave tried to acquire Core Scientific for $9 billion earlier this year. Core Scientific shareholders voted against the proposed deal. Core Scientific shares sank 7% Tuesday.
During CoreWeave’s quarterly earnings call on Monday, JPMorgan Securities analyst Mark Murphy asked if the delay was related to Core Scientific, but Intrator declined to name the company. At another point in the call, the CEO suggested that just one data center, not multiple sites, were affected.
“There was a problem at one data center that’s impacting us, but there are 41 data centers in our portfolio,” Intrator said.

At a different point in the call, CoreWeave’s CFO Nitin Agrawal said the delays stem from “a single provider, data center provider partner.”
When reached for comment about how many sites were affected, CoreWeave did not provide a number and pointed to Intrator’s statements on the earnings call and during his “Squawk on the Street” interview.
CoreWeave, which provides infrastructure for artificial intelligence companies, reported third-quarter results on Monday that showed $1.36 billion in revenue for the period, up 134% from $583.9 million a year ago. But CoreWeave now sees 2025 revenue coming in between $5.05 billion and $5.15 billion, below the average analyst estimate of $5.29 billion.
Intrator told CNBC on Tuesday that CoreWeave has teams of employees working with contractors and Core Scientific at those sites “every single day” to get things back on track.
“It became apparent to us in Q3 that there were delays at the facility,” Intrator said. “CoreWeave responded by deploying our own boots on the ground to ensure that everything was being done in order to move those facilities along as quickly as possible.”
Intrator told analysts on Monday that the delays would not affect its backlog or get the full value from contracts.
Core Scientific did not immediately respond to a request for comment.
CoreWeave has been on a deal-making blitz as big tech companies and AI startups race to build out their computing infrastructure.
The company announced in September that it agreed to provide Meta with $14.2 billion of AI cloud infrastructure, just days after expanding its contract with OpenAI to $22.4 billion.
Every weekday the CNBC Investing Club with Jim Cramer holds a “Morning Meeting” livestream at 10:20 a.m. ET. Here’s a recap of Tuesday’s key moments. 1. The S & P 500 and Nasdaq were down Tuesday as Big Tech was pressured following CoreWeave’s quarterly results Monday evening. The AI infrastructure provider disappointed investors after lowering its revenue outlook. Shares of CoreWeave plunged around 14%. Regarding the broader AI trade, Jim said, “I’m getting antsy about the fact that there’s too much borrowed money now starting to go into the data center.” However, Jim is not currently advocating changes to the portfolio. Wall Street also focused on soft labor market data after ADP’s payroll tracker showed a weekly decline of 11,250 jobs on average for the four weeks ending Oct. 25. 2. Linde shares were up over 1% Tuesday after UBS upgraded the industrial gas giant to a buy from a hold-equivalent rating. The analysts, who cut their price target to $500 from $507, said that earnings-per-share growth in 2026 will be a positive catalyst for Linde. This is a reassuring call for the recently lagging Club holding. After all, Linde’s pricing power has allowed the company to deliver earnings beats quarter after quarter despite the macroeconomic backdrop. 3. Nvidia stock shed around 3% on Tuesday after SoftBank announced that it sold its entire stake in the chipmaker. Weakness among AI-related names didn’t help investor sentiment, either. The sale of Nvidia stock is a source of cash that will be used to fund SoftBank’s whopping $22.5 billion investment in OpenAI, CNBC reported Tuesday. The news doesn’t make us concerned about Nvidia. We maintain our “own, don’t trade” thesis on shares. Instead, it adds to our aforementioned caution around mounting debt from the AI data center boom. 4. Stocks covered in Tuesday’s rapid fire at the end of the video were: CoreWeave, Paramount Skydance , Amgen , Dutch Bros , and Coterra Energy. On Wednesday at 6:30 p.m. ET, Jim will be signing copies of his new book, “How to Make Money in Any Market,” at the Atlantic Avenue Barnes & Noble in Brooklyn.
