At a late-night airport, an investment partner booked the last flight of the evening. Along with a change of clothes in his suitcase was a contract revised overnight. He had to arrive before dawn to intercept the founder of an embodied AI company—more precisely, to wait outside the founder's office door. The founder had been chased all day by calls from over a dozen institutions and had simply turned off his phone to avoid them. Little did he know that upon opening the door, he would find two investors already seated in the hallway, one with a contract open to the signature page.
This is now a daily occurrence in the hard tech fundraising scene this year.
In the past, investors waited at doors to chat more and secure a larger share. Now, some directly slap a bridge loan transfer receipt on the table: "Forget about the funding pace for now. This money can arrive today. Take it and use it."
The earliest whispers of VCs doing bridge loans came about two years ago.
A public relations contact from a fund of funds mentioned their recent busy schedule, saying, "We've been swamped lately, just providing bridge loans to portfolio companies." Back then, IPO exits were still clogged, investment institutions were tight on cash, and they were very cautious about uncertain projects.
Some companies couldn't raise funds, their cash flow was on the verge of breaking, and existing shareholders were reluctant to invest further. But without a helping hand, the project was staring failure in the face. Reluctantly, they resorted to a bridge loan as an emergency measure.
But starting this year, bridge loans have suddenly become a hot commodity eagerly pursued by VC firms.
At a recent closed-door meeting, investors privately discussed a new trend—bridge loans.
"We've seen many such projects recently. In the past, it was a last resort for emergencies; now, it's seen as a way to lock down projects."
A VC partner who closed several bridge loans within a year talks about them more animatedly than discussing regular equity investments. A vivid industry saying describes this shift: this business is undergoing a persona reversal.
It used to be a life-saving injection in the ICU—a project's funding chain was about to snap, and existing shareholders reluctantly advanced some money to pull it back from the cliff's edge. Now, it has transformed into a door-knocking ticket for snagging deals.
A short-term loan with an annual interest rate around 3%—why are cash-flush investors so obsessed with it? The answer lies in a seemingly insignificant additional clause in the contract.
Deconstructing "Loan-to-Equity Conversion"
Bridge loans themselves are not new.
Institutions lending money to portfolio companies for cash flow is perfectly natural.
The real killer move is that investors often slip a "conversion right" into the contract: when the company raises its next funding round, a portion of this loan can be directly converted into equity investment funds. It can even be tied to the company's operational milestones—achieving certain technical metrics, scaling a product line—allowing the conversion quota to increase.
This setup is almost a guaranteed win for investors.
If the company's valuation keeps rising, investors convert equity at the "discounted price" locked in when the loan was made, essentially buying an advance ticket to the next round at a pre-determined price.
If the company doesn't develop smoothly, investors don't lose either. They can simply choose not to convert, collect the principal plus interest, offering a much higher safety margin than pure equity investment.
The industry has given this tactic a fitting nickname—"call option," except the premium is replaced by interest, and the strike price is replaced by a discount on the next round's valuation.
This kind of operation can be done openly, but not without boundaries.
Regulators have long had rules: private equity funds providing loans or guarantees to portfolio companies cannot exceed one year in term, and the amount cannot exceed 20% of the fund's paid-in capital.
In other words, this business is born with a "limited purchase" attribute, which explains why institutions are scrambling to fully utilize that 20% quota.
Be late, and the spot might be taken by someone else.
Similar tactics actually appeared around 2018, but with a simpler purpose—purely to secure a position. A Term Sheet (TS) was signed, the formal agreement wasn't finalized yet, or pre-investment restructuring was pending. The company needed money urgently, so the institution advanced a sum.
Sometimes, companies weren't short on cash at all, but to lock investors in more tightly, it was the company that proactively requested the bridge loan. Back then, loan terms were usually kept within six months, and what investors cared about most was that the conversion right wasn't time-bound.
Even if the loan matured, investors could unilaterally extend it, while the company was prohibited from repaying early; otherwise, the investor's conversion right would be voided.
Now, this playbook has been repackaged. What investors seek is no longer just "locking down the project," but buying an advance "spot reservation insurance" for potential unicorns.
Companies shed short-term repayment cash flow pressure via "loan-to-equity conversion," while investment institutions use it to pre-book subscription quotas for the next round, avoiding dilution of their stake by the giants swarming in later.
How hot is this business? Even banks are starting to feel threatened.
A company making core components for robots was simultaneously negotiating funding with a bank and its existing VC shareholder. On the bank's side, the account manager spent over half a year on processes—persuading risk control, conducting site visits, securing quotas—finally getting the credit line approved with a decent interest rate, thinking it was a sure deal.
When calling to inform the company, the response was casual: "Sorry, we've already accepted a bridge loan from our VC—similar interest rate, but they're willing to convert most of the loan directly into equity, so our immediate cash pressure is actually lower."
The bank tried to salvage the situation by pulling out the "investment-loan linkage" card, only to discover policy regulations limit banks to subscribing to a maximum of 2% of a company's equity. Compared to the VC's conversion quotas of tens or hundreds of millions, they essentially had no competitive edge.
Hot Money Siege
The sudden clustering of bridge loans boils down to overheated financing in certain sectors.
Embodied AI and AI chips are currently the two sectors that can "burn money" the most and also "attract capital" the most.
In the first half of this year, the total financing amount in China's embodied AI field has already surpassed that of the entire previous year—different institutions' statistical calibers vary, but figures consistently fall within the range of 40-60 billion RMB, with over 200 financing events.
Behind the buzz is brutal stratification. The top twenty companies have scooped up about 70% of the industry's total money, leaving the remaining two hundred-plus companies to share an average of just tens of millions each—barely enough to cover expenses.
Valuations of the leading few companies have already crossed the 20 billion RMB mark. One company raised 4.5 billion RMB in just four months, equivalent to one-third of the total financing of the two hundred-plus mid and tail-end companies combined.
How fast can the funding pace get?
One day in early March this year, three different embodied AI companies almost simultaneously announced completing new funding rounds, with amounts ranging from hundreds of millions to over two billion RMB—as if they had agreed to announce together, leaving onlookers stunned.
An investor privately grumbled about a case: a brain-computer interface company hadn't even finalized the previous round's funds before launching the next, with its valuation directly doubling or tripling.
This isn't an isolated case—many hard tech projects haven't received funds from the previous round before the next two rounds are already negotiated. With funding cycles compressed like this, the mindset of existing shareholders is可想而知: watching their portfolio company launch a new round, but their subscription quota has already been snatched by others.
Financing for top companies is incredibly lively. For particularly hot projects, due diligence isn't possible, and investment decision time is extremely short. Even so, investors are still fighting to get in.
For top projects, investors' posture is almost "we'll invest even if we have to kneel." No valuation adjustments, no buyback requirements, no exhaustive due diligence—just follow-on investment and immediate transfer.
To squeeze in, institutions not only dare not push down valuations but also compete on who can offer more resources. Supply chain connections, local policy subsidies, customer introductions, even computing power support—everything must be put on the table.
Even manufacturing giants have entered the fray. One automaker invested in four or five embodied AI companies within half a year. Rather than diversifying bets, it's more like buying insurance for their future production lines in advance.
An industry insider summarized the changes in this sector over the past year-plus with three words: acceleration, differentiation, restructuring.
Others caution that the recent wave of collective influx was largely "positioning" investments driven by fear of missing the window, not necessarily every dollar betting on the right direction.
Data shows that in Q1 this year, fundraising in the venture capital market increased over 80% year-on-year, with 90% of the money flooding into sectors like AI, robotics, world models, quantum technology, controlled nuclear fusion, integrated circuits, and commercial aerospace.
Hot money clustering in a limited number of top projects directly leads to shorter and shorter funding cycles and valuations rising to unsettling heights.
Bridge loans plus "loan-to-equity conversion"恰好 offer existing shareholders a face-saving补救方案.
Using the sentiment of "brother, here's some cash to burn first" to lock in a guaranteed quota for the next round in advance.
The company gets same-day cash flow, the investor secures an anti-dilution entry ticket; even if a deal isn't finalized later, they at least gain a reputation for "providing timely help."
Deeper down, this is also a survival tactic born out of pressure. Everyone fears being the one left empty-handed when the music stops in this game of hot potato.
Timely Rescue or Advance Land Grab?
In the actual operations of VCs/PEs, "bridge loans" mainly appear in two scenarios.
One is for extremely sought-after projects, used to secure investment rights in advance. The other is when a portfolio company faces cash flow strain, and existing shareholders step in for an emergency lifeline.
The first playbook isn't original to domestic VCs; top Silicon Valley capital has played it before.
A typical套路 is: before a project officially launches its next high-valuation funding round, leading institutions first give the founder a bridge loan or a SAFE agreement, with no定价 in the current period. It's agreed that when the company triggers the next funding round, it automatically converts to equity at a discount of around 20% off the new round's valuation.
The company gets cash on the same day to expand and hire, while the VC seizes the opportunity to insert an "exclusivity clause" into the agreement. If the company is found secretly contacting other institutions during the exclusivity period, the bridge loan typically must be repaid within days, along with a hefty penalty interest.
On one side are red-hot top projects, with VCs offering bridge loans as敲门砖,恨不得 stuffing money directly into the founder's pocket. On the other side are ordinary projects that can't secure a new round, with existing shareholders wielding bridge loans as a "noose," writing条款 increasingly stringent.
From "betting on the nation's destiny" style all-in bets to "calculating every margin" style meticulous planning, this bridge loan frenzy is essentially collective risk aversion in the primary market.
Capital is both afraid of missing the next humanoid robot unicorn and fed up with endless high-valuation bubbles and迟迟兑现不了的 paper gains.
So, everyone has tacitly chosen the most shrewd path: aiming the gun at the future while first fastening a bulletproof rope around their waist.
For entrepreneurs, this "same-day cash" is indeed tempting.
But there's no free lunch. When investors no longer make equity gambles based purely on belief, behind every seemingly timely-help loan contract, exclusivity, discounts, and exit strategies are often quietly written in advance.
As for whether the investor waiting in the hallway at the beginning secured that investment quota, no one knows. But one thing is certain: on the next凌晨 flight, there will be another person who has booked their ticket.
