Queer dating app Grindr is planning to go public by merging with a Singapore-based blank-check company in a deal that would value the company at roughly $2.1 billion.
West Hollywood-based Grindr said Monday that it has agreed to merge with Tiga Acquisition Corp., a special purpose acquisition company (SPAC) trading on the New York Stock Exchange. Grindr plans to raise at least $384 million from the transaction, with plans to use the funds to pay down debt and further grow its business.
Since launching in 2009, Grindr has grown to around 11 million monthly active users globally, roughly 80% of whom are under 35 years old. The app, which is free to download on iOS and Android devices, has emerged as the queer community’s most popular answer to the Match Group-owned Tinder, which caters primarily to straight singles. Grindr does compete with other queer dating apps including HER, mainly used by lesbian women; Lex, for queer users; and Feeld, an app for polyamorous connections.
Grindr said it generated $147 million in revenue last year, a 30% increase from the year prior. That revenue growth was fueled by an increase in the number of users paying for the app’s premium subscription, which totaled 723,000 at the end of 2021—up 31.5% year-on-year.
Grindr is pursuing a SPAC merger despite a sharp slowdown in SPAC deals amid heightened regulatory scrutiny, as well as a wider stock market correction that has pumped the brakes on IPO deal volume this year. Still, SPAC deals remain a quicker way for companies to list on public markets by side-stepping much of the regulatory red tape around traditional IPOs.
The app recently came under fire after a Wall Street Journal article exposed Grindr’s years-long practice of selling users’ precise location data to the highest bidder—a practice that runs the risk of outing some users’ sexuality and compromising their safety. The company countered the report by claiming it had implemented new privacy policies to prevent the sharing of “precise location” data.

Two LA Startups Raised $2.37B to Build What AI Needs
🔦 Spotlight
Happy Friday, LA.
The largest checks in tech are increasingly going toward companies trying to build their way out of America’s biggest physical constraints.
This week, two Los Angeles startups raised a combined $2.37 billion in equity to tackle two particularly urgent ones: how the country manufactures critical hardware and where it will find enough electricity to power the AI era.
Torrance-based Hadrian is building highly automated factories for defense and aerospace. El Segundo’s Valar Atomics wants to manufacture nuclear reactors at scale. Different industries, same underlying bet: the next generation of technology will depend on our ability to produce physical infrastructure much faster than we do today.
Hadrian raised $1.37 billion in Series D funding, bringing its valuation to $7.87 billion. The company plans to use the capital to open new factories, expand research and development, and increase its capacity to produce critical defense, aerospace and industrial systems.
Hadrian’s pitch is straightforward, if wildly ambitious: America needs to relearn how to build things and build them quickly.
Its factories combine skilled workers with AI, robotics and proprietary software to manufacture precision components and, increasingly, complete mission-critical systems. Its customers include defense giants such as Lockheed Martin and RTX, along with newer players like Anduril.
The company has come a long way from simply making aerospace parts. Hadrian is positioning itself as a piece of America’s industrial infrastructure, offering manufacturers a way to rapidly scale domestic production at a time when wars abroad, strained supply chains and growing defense demands have made the country’s manufacturing gaps increasingly difficult to ignore.
Investors are clearly buying the argument. The new round comes just over a year after Hadrian raised $260 million, suggesting that “reindustrialization” has officially graduated from venture capital buzzword to billion-dollar investment thesis.
Meanwhile, roughly 15 miles away in El Segundo, Valar Atomics is moving even faster than its enormous ambitions suggested.
When we last wrote about Valar, the company was reportedly raising $450 million at a $2 billion valuation and racing to prove that nuclear energy could move on AI’s timetable. Now, it has closed a $1 billion Series B led by Sequoia Capital, secured an additional $200 million credit facility and reportedly reached a $6 billion valuation.
Valar is developing standardized, factory-built nuclear power plants designed to avoid the enormous costs and decades-long construction timelines associated with traditional nuclear projects. Its goal is not merely to build a working reactor, but to eventually manufacture fleets of them.
That ambition also sounds considerably less theoretical than it did when we first covered the company. In June, Valar’s Ward 250 reactor achieved a self-sustaining nuclear reaction. Just one week later, the company demonstrated the reactor generating electricity to power an Nvidia Blackwell system. Valar now says the new funding will help it move from proving its technology works to producing reactors at scale.
The timing is no coincidence. AI’s enormous appetite for electricity is forcing the tech industry to confront a basic reality: the cloud still has to plug into something. Training models and operating massive data centers will require far more reliable power, and nuclear energy is rapidly becoming one of Silicon Valley’s favorite answers.
Hadrian and Valar may be solving different problems, but their unusually large rounds point to the same shift. AI can design, predict and automate, but it cannot manufacture a missile component or generate a megawatt of electricity on its own. That requires factories, energy systems, supply chains and a great deal of capital.
For years, venture-backed companies competed to build the software layer. Now, some of the biggest bets are being placed on the infrastructure underneath it.
The future may run on AI. But first, someone has to build what keeps it running.

This Torrance Startup Just Raised $1B to Mass-Produce Hypersonic Missiles
🔦 Spotlight
Happy Friday, Los Angeles.
Castelion has spent the past four years trying to prove that hypersonic missiles do not need to take decades to develop or cost so much that the military can only afford a limited supply.
Now comes the harder part: producing them at scale.
The Torrance-based defense startup raised a $1B Series C at a $13B valuation. The financing includes $800M in equity and a $250M revolving credit facility, making it one of the largest recent raises for an LA defense technology company.
JPMorganChase’s Strategic Investment Group, Andreessen Horowitz and Carlyle co-led the round. Lightspeed Venture Partners, Lavrock Ventures, Altimeter, General Catalyst, T. Rowe Price and LA-based Interlagos Capital also participated.
Castelion will use the capital to ramp production of Blackbeard, its low-cost hypersonic strike missile, while developing a longer-range precision weapon and new defensive systems. Hundreds of millions of dollars will go toward expanding manufacturing at Project Ranger, the company’s 1,000-acre production campus in New Mexico.

Blackbeard was designed in California, will be built in New Mexico and is expected to enter service in 2027. Castelion says it has already secured more than $500M in U.S. military contracts over the past 18 months and moved the missile from a clean-sheet concept to an official program in fewer than four years.
That timeline is central to Castelion’s pitch. Traditional defense programs are often associated with long development cycles, limited production runs and eye-watering costs. Castelion is applying the rapid testing and vertically integrated manufacturing approach popularized by commercial space companies to weapons production.
But a $13B valuation changes the standard. Castelion is no longer being judged as a promising startup with an impressive prototype. It is being funded like a company expected to become a major part of the American defense industrial base.
The question is no longer whether a startup can build a hypersonic missile. It is whether one can manufacture thousands of them without losing the speed, discipline and cost advantages that made it disruptive in the first place.
For LA’s defense ecosystem, that shift matters. The region has become home to a growing number of companies promising to modernize how America builds critical hardware. Castelion now has the capital, contracts and facilities to show what happens when that promise reaches the factory floor.
The next test will not be in a pitch deck. It will be in production.
