Venture capital has a structural bias toward narrative, and fraud is what happens when the narrative leaves the ground entirely. That's the thread running through this episode, which separates three categories usually lumped into one bucket called "startup fails." Slideware is a product that exists primarily as a pitch deck — the pitch is the product. Vaporware is a product announced with enormous fanfare that never ships — the announcement is the product. And then there's the third category: founders who didn't even pretend, where the pitch deck was the whole company.

Builder.ai is the anchor case. The London company raised over $450 million from Microsoft, SoftBank, and others on the promise that AI would let anyone build an app without code. The reality was a large team of human developers in India doing the assembly — a chat interface on one end and a person on the other, an old trick dating back to the Mechanical Turk. It collapsed into administration in 2025. Delve ran a smaller version of the same playbook: Y Combinator-backed "automated compliance" that was largely humans typing into spreadsheets and charging software margins. Rothenberg Ventures pushed slideware to the fund level, complete with a literal slide in the office, until the SEC charged Mike Rothenberg with misappropriating investor funds.

Theranos and Frank sit in the purest category. Elizabeth Holmes didn't have a partial prototype she hoped to improve — she had a device that didn't work and a story that did. Charlie Javice fabricated millions of user accounts to sell Frank to JPMorgan for $175 million. The uncomfortable throughline: the line between visionary and conman gets drawn retrospectively, based entirely on whether it worked. If you ship, you believed before the world caught up. If you don't, you were a liar. The system deliberately blurs that line, and fear of missing out has become an anti-due-diligence strategy.

#5288: Slideware, Vaporware, and the Founders Who Never Built Anything

Herman
...which is why the deck is the only artifact anyone actually remembers. Nobody frames the cap table.
Corn
Daniel's question this week is about the part of venture capital that nobody puts on a stage. He's pointing at the conmen and con women who cook up a great slide deck and hope to ride an easy money train while working on something they may not actually believe in. The field has a name for it — slideware — products that are wildly over-pitched or simply never make the leap from slideshow to real thing. He wants the notorious examples. The slideware, the vaporware, and the startups that didn't even pretend to be building something.
Herman
Three separate categories, and I'm glad he drew the distinction, because most coverage lumps them into one bucket called "startup fails."
Corn
So we're separating the slide from the vapor, the vapor from the outright fraud, and asking why the venture capital world keeps falling for it. Because it keeps falling for it. Builder dot ai collapsed last year after raising four hundred fifty million dollars. That's not a rounding error.
Herman
Four hundred fifty million, and the artificial intelligence was mostly humans in India answering prompts. Let's define terms before we get to the bodies.
Corn
Slideware. A product that exists primarily as a pitch deck. Compelling narrative, gorgeous mockups, no working technology behind it. The product is on the slides and nowhere else.
Herman
Vaporware is different. A product that's announced, sometimes with enormous fanfare, but never ships — or ships so late and so crippled it might as well not exist. Vaporware can be intentional or it can be overpromising that curdles into underdelivering.
Corn
So slideware is the pitch being the product. Vaporware is the announcement being the product.
Herman
That's the cleanest way to say it. Slideware is a fundraising strategy. Vaporware is a marketing strategy. They overlap constantly, but they're not the same move.
Corn
And then there's the third category Daniel flagged — the ones who didn't even pretend. No product, no technology, no intention of building either. The pitch deck is the whole company. The company is the pitch deck.
Herman
Theranos sits there. Frank sits there. We'll get to both.
Corn
So why does the system keep generating these people? That's the question underneath Daniel's question. Why does an industry that prides itself on pattern-matching and due diligence keep wiring money to stories?
Herman
Because the incentives are set up to reward the story. That's the structural answer, and it's not cynical, it's arithmetic.
Corn
Walk me through the arithmetic.
Herman
A venture fund is playing a power law game. Out of thirty investments, twenty-five will be worth zero. Three will return their money. One or two have to return a hundred times the investment to make the whole fund work. So when a partner sits in a pitch meeting, they're not asking "is this company likely to succeed." They're asking "could this company be the one that returns the fund."
Corn
Which means a founder who says "we're building a boring but profitable tool for dental offices" gets a polite nod and no term sheet.
Herman
A founder who says "we're reinventing computing" gets a second meeting. The boring profitable company caps out at a five times return, which does nothing for the fund. The moonshot is the only thing that matters.
Corn
So the structural bias isn't toward fraud, exactly. It's toward narrative.
Herman
It's toward narrative, and fraud is what happens when the narrative leaves the ground entirely. The founder knows more about their product than the investor does. That's the information asymmetry. Due diligence is expensive, it's time-consuming, and in a hot sector it's often skipped because someone else will write the check first.
Corn
Fear of missing out is a due diligence strategy.
Herman
It's an anti-due-diligence strategy. And Silicon Valley has spent decades celebrating founders who exaggerated their way to success. "Fake it till you make it" is a cultural value. The line between visionary and conman gets drawn retrospectively, based entirely on whether it worked.
Corn
If you ship, you were a visionary who believed before the world caught up. If you don't, you were a liar.
Herman
And the founder often doesn't know which one they are until the end. That's the uncomfortable part.
Corn
Let's get to the examples. Start with the slideware that became fraud.
Herman
Builder dot ai. London-based, raised over four hundred fifty million dollars from Microsoft, SoftBank, a long list of serious names. The pitch was that their artificial intelligence would let anyone build an app without writing code. Drag and drop, describe what you want, the AI assembles it.
Corn
The reality was a large team of human developers in India doing the assembly.
Herman
The AI was a chat interface on one end and a human on the other. Which is actually a very old trick — the Mechanical Turk was an eighteenth-century chess-playing automaton that turned out to have a person hidden inside the cabinet.
Corn
So the slide said "proprietary AI platform." The reality was offshore labor arbitrage with a chatbot in front.
Herman
And the founder, Sachin Dev Duggal, had been accused of fraud in a previous venture. That's the detail that makes it a pattern, not a one-off mistake. When Builder dot ai collapsed into administration in twenty twenty-five, the whole thing unwound in public.
Corn
Four hundred fifty million dollars, and the product was a staffing agency wearing an AI costume.
Herman
That's the slideware-to-vaporware-to-fraud pipeline. The pitch was AI. The reality was humans. The money was real. The company was never what it claimed to be, and at some point the gap between the slide and the substance becomes the crime.
Corn
You said due diligence gets skipped. Microsoft and SoftBank both wrote checks.
Herman
Microsoft and SoftBank both wrote checks. That's the part that should make everyone pause. These are not naive angel investors. These are institutions with armies of analysts. And they still funded a company whose core technology was humans in another country.
Corn
Because the narrative was too good to check too hard. Anyone can build an app. The total addressable market is every person with a phone. That's a hundred-times story if it's real.
Herman
And if it's not real, you've spent four hundred fifty million to find out.
Corn
Next case. Rothenberg Ventures.
Herman
Mike Rothenberg. Raised a hundred million dollar fund. Positioned himself as the founder's founder — a new kind of venture firm that would be a friend to founders, throw lavish parties, build a "founder's space" with a slide.
Corn
A slide. In the office.
Herman
A literal slide. The office had a slide. Which is such a perfect metaphor that I almost don't need to say anything else.
Corn
Say it anyway.
Herman
The SEC charged him in twenty sixteen with misappropriating investor funds. He was using the money for personal expenses and to fund his other ventures. The pitch was a new kind of venture firm. The reality was a guy spending other people's money on himself.
Corn
So that's slideware at the fund level. The fund itself was the product, and the product was a lifestyle.
Herman
The slide was the slide. The actual slide, in the office, was the product.
Corn
And then there's Delve.
Herman
Y Combinator-backed compliance startup. The pitch was automated compliance for startups. Feed us your data, our software handles the regulatory paperwork. Turns out it was largely humans doing the work manually and charging software margins.
Corn
Same playbook as Builder dot ai, smaller scale.
Herman
Y Combinator removed Delve from its directory in twenty twenty-four once the manual operation became public. The slide said "automated compliance platform." The reality was people typing into spreadsheets and charging as if a robot did it.
Corn
The pattern in all three — Builder, Rothenberg, Delve — is that the founders didn't set out to build a product. They set out to build a narrative. The product was the pitch.
Herman
The pitch was the product. The money was the fuel. And the fuel burned until someone noticed the engine wasn't there.
Corn
Now, the distinction you made earlier — not all slideware is fraud. Some founders believe they can build what they're pitching. They just haven't yet.
Herman
Right, and this is where the conversation gets uncomfortable, because the system deliberately blurs that line. A founder who says "we haven't built it yet but we will" is doing what every founder does. The difference between that and a conman is whether they eventually ship.
Corn
And that difference is only visible in hindsight.
Herman
Only in hindsight. Elizabeth Holmes said she could run hundreds of tests from a single drop of blood. She couldn't. The technology didn't exist. She knew it didn't exist. But she raised billions and partnered with Walgreens before it collapsed.
Corn
That's the "didn't even pretend" category. She didn't have a partial prototype that she hoped to improve. She had a device that didn't work and a story that did.
Herman
Convicted of fraud in twenty twenty-two. And the question that always hangs over Theranos is what would have happened if the technology had eventually worked. If she'd faked it and then made it, she'd be a hero. The story would be "she believed before the world caught up."
Corn
Which is the retrospective line-drawing you mentioned. The verdict depends on the outcome, not the conduct.
Herman
And that's a terrible way to run an ecosystem, but it's exactly how the ecosystem runs.
Corn
Frank is the other one in that category.
Herman
Charlie Javice. Student financial aid startup that claimed to simplify FAFSA applications. She sold it to JPMorgan for one hundred seventy-five million dollars. The pitch was millions of users. The users were fake.
Corn
Fabricated accounts.
Herman
Fabricated millions of user accounts to make the acquisition look worth it. JPMorgan bought a website and a spreadsheet of people who didn't exist. Convicted of fraud in twenty twenty-four.
Corn
The product was a website. The users were fake. The acquisition was real. That's the whole story.
Herman
And it's the purest form of what Daniel's asking about. There was never a technology problem to solve. There was never a hard engineering challenge. There was just a story about scale, and the scale was invented.
Corn
Let's talk about vaporware as a strategy, because it's not always fraud.
Herman
Microsoft in the nineteen nineties. They were notorious for announcing features years before they shipped. The purpose was to freeze the market — if you're a competitor and Microsoft says they're building the thing you're building, your customers wait for Microsoft's version.
Corn
So the announcement is the product. The product may eventually ship, but the announcement did the work.
Herman
It's a marketing strategy, and it's deceptive, but it's not the same as Builder dot ai. Microsoft did eventually ship most of what they announced. The vapor was a timing weapon, not a lie about what existed.
Corn
And then there's the media layer, which makes all of this worse.
Herman
Tech media amplifies narratives because narratives drive clicks. A founder who says "we're building a useful tool for payroll" gets no coverage. A founder who says "we're changing the world" gets a profile. The profile attracts investors. The investors attract more media. It's a feedback loop where the most outrageous claims get the most attention.
Corn
So the conman isn't just exploiting investors. They're exploiting the entire attention economy.
Herman
And the attention economy is happy to be exploited, because the conman's story is a better story than the honest founder's story. "We automate compliance" is more interesting than "we have a team that does compliance manually but carefully."
Corn
Which is why the honest version never gets funded. The honest version is boring.
Herman
The honest version is boring and the boring version doesn't return the fund. So the system selects for the exciting version, and sometimes the exciting version is a lie.
Corn
What does this do to the legitimate founders?
Herman
It poisons the well. When slideware and vaporware become normalized, investors get more cynical. Due diligence gets more invasive. The bar for raising money goes up for everyone. The conmen make it harder for the honest builders.
Corn
And the honest builders are already fighting the power law. They're already fighting the fact that their boring profitable company is less attractive than a moonshot.
Herman
The fraudsters raise the cost of capital for everyone. An investor who's been burned by a Builder dot ai is going to demand more proof, more traction, more revenue before writing the next check. The honest founder who was already struggling to get attention now has to clear a higher bar.
Corn
So the system punishes the people who were telling the truth all along.
Herman
And the fraudsters have already moved on to the next narrative. They don't stick around to feel the consequences. They take the money, the company collapses, and they're pitching something else six months later.
Corn
Sachin Dev Duggal had a previous fraud accusation before Builder dot ai. That's the pattern.
Herman
That's the pattern. The conman doesn't stop being a conman when the company dies. The company dying is just the end of one story and the beginning of the next.
Corn
So is the system broken, or is it working exactly as designed?
Herman
I think that's the question. The VC model is not going away. The power law means funds need to swing for the fences, which means they will always be susceptible to stories that promise the moon. The cycle of hype and collapse is a feature, not a bug.
Corn
The fraudsters are the cost of doing business.
Herman
They're the cost of a system that rewards belief over evidence. The system needs people to believe in the future before the future exists. That's what venture capital is. And if you need people to believe in things that don't exist yet, you're going to attract people who exploit that belief.
Corn
The conmen are not a bug in the system. They're a feature of a system that runs on belief.
Herman
And the question is whether there's a way to structure incentives that rewards substance over storytelling. I don't know that there is. The power law is the power law.
Corn
You'd have to change the power law. You'd have to make boring profitable companies attractive to venture funds.
Herman
Which would require a completely different fund structure. A fund that returns three times by investing in boring profitable companies is a great fund by most standards. It just doesn't attract limited partners who are comparing it to the fund that returned twenty times.
Corn
So the limited partners are part of the problem.
Herman
Everyone's part of the problem. The limited partners want the twenty times return. The general partners want to raise the next fund. The founders want to build something big. The media wants the story. The conman is just the person who figures out how to give everyone what they want.
Corn
Until the collapse.
Herman
Until the collapse. And the collapse is always someone else's problem.

Hilbert: The slide that said "Proprietary AI Algorithm" was a stock photo of a brain with circuit board lines overlaid.
Corn
Sorry?

Hilbert: I did due diligence for a small firm in Menlo Park in the late nineties. My job was to check out the technology behind the pitches. I was supposed to catch the slideware.
Herman
How'd that go?

Hilbert: I visited a startup that claimed to have built a revolutionary AI-powered search engine. The office was a rented room above a nail salon. The AI was a guy named Steve in the back room manually typing search results.
Corn
Steve.

Hilbert: Steve. Nice guy. He'd been a reference librarian. The pitch deck had a slide that said "Proprietary AI Algorithm" with a stock photo of a brain and some circuit board lines. I wrote it up in my report. My boss told me to focus on the market opportunity, not the technical details.
Herman
The firm invested anyway.

Hilbert: Two million dollars. The company folded eight months later. Steve went back to being a librarian.
Corn
You kept the deck.

Hilbert: It's in a box in my garage. The brain slide is still in there.
Herman
Twenty-five years later, and the same playbook is getting four hundred fifty million from Microsoft.

Hilbert: The scale is different. The playbook is the same.
Corn
Do you think the system is broken?

Hilbert: No. I think it works exactly as designed. It's a machine for converting stories into money. Sometimes the stories are lies. But everyone in the room wants to believe the story, because believing the story is how you make money. The only people who get hurt are the ones who can't afford to lose.
Herman
That's the part that never shows up in the pitch deck. The limited partners can afford to lose. The employees who took stock options can't. The customers who bought the product can't.

Hilbert: I once tried to pitch a startup myself. Fresh bread delivered to your door every morning. Great deck. Raised fifty thousand from my brother-in-law. The bread was terrible. The company lasted three weeks.
Corn
That's the most honest slideware I've ever heard of.

Hilbert: The deck was honest. The bread wasn't.
Herman
The difference between you and Elizabeth Holmes is that your failure cost fifty thousand dollars and a family argument.

Hilbert: I never claimed the bread was AI. It was just bad bread.
Corn
The scale question is the whole question. The same behavior at fifty thousand dollars is a failed bakery. At four hundred fifty million it's a fraud conviction.

Hilbert: They don't convict you for bad bread.
Herman
They convict you for lying about the bread while taking nine figures.

Hilbert: The lying is the same in both cases. The money is what changes the crime.
Corn
The money is what changes the story. Nobody writes a profile about a failed bakery. They write profiles about the four hundred fifty million dollar AI company that turned out to be humans.

Hilbert: The profile is part of the machine. The story is the product. That's what you two have been saying.
Herman
The story is the product until the story stops working.

Hilbert: Then it's a different story. The story about the collapse. That one gets clicks too.
Corn
The media gets two stories out of every fraud. The rise and the fall.

Hilbert: The conman gets both.
Herman
The conman gets the money and the profile. The collapse is just the second act.

Hilbert: I should go. I have a box in the garage to not think about.
Corn
The one thing I keep coming back to is the line between visionary and conman being drawn by the outcome, not the conduct. Elizabeth Holmes did the same thing as a founder who eventually shipped. The only difference is whether the technology caught up to the story.
Herman
That means the system can't tell the difference in real time. It can only tell the difference after the money is gone. Which is why the fraudsters will always be with us — not because they're clever, but because the system needs belief more than it needs evidence.
Corn
The tools of deception are getting cheaper. AI can generate a pitch deck, mockups, a fake demo, a fake product video. The slideware of tomorrow is going to look more real than the real products of today.
Herman
Which means the due diligence problem gets harder, not easier. When the fake and the real are indistinguishable at the pitch stage, the only way to tell the difference is to wait and see what ships.
Corn
By then the money's already spent.
Herman
