Show HN: FastPitchDeck – AI to generate VC-ready pitch decks
by ramyavarahagiri | 2025-06-30 17:45:23+00:00
For my last startup, I spent over 100 hours tweaking pitch decks in PowerPoint, Google Slides, and Figma. Every investor asked for something different, and I kept getting lost in formatting hell instead of focusing on storytelling.

After talking to 50+ founders, I realized this was a universal problem:

Wasting time on design instead of messaging.

Struggling to structure a compelling narrative.

No ‘source of truth’ for updates across versions.

So I built FastPitchDeck: a tool that generates investor-ready decks in minutes, not days. It uses AI to suggest slide structures, auto-formats everything, and keeps decks synced with your startup’s metrics.

Key features: AI-powered outline generator (based on YC/Techstars best practices) One-click styling (no more pixel-pushing) Live data integration (tie slides to your Stripe, Google Analytics, etc.) Collaborative editing (founder-friendly, no design skills needed)

Try the free beta here: https://fastpitchdeckai.vercel.app/ (no VC required, just founder love).

This is very neat. One piece of feedback and a gripe I have with a lot of these is that missed or extra characters throw off the entire next sequence and essentially require backing up to deal with them, as opposed to wrong characters which are fine to just be mistakes you move on from. It'd be great to have some detection for when the user is continuing that re-aligns their string.

The article is about entry level jobs. If I brought in two entry level developers to do the current POC project where I did the discovery, design and architecture, it would slow me down as opposed to feeding in the requirements to ChatGPT and letting it spit out the technical simple code that I require where the complexity is in the orchestration and business requirements.

I have never once said “it sure would be nice to have a few more junior devs. That would really increase our velocity”.

As someone who is responsible for getting projects done on time, within budget and meets requiremenga, why would I push for hiring fresh entry level devs instead of hiring a mid level dev with experience for only 20-30% more? The spread isn’t that great for enterprise developers.

It’s even more true now that I can push for hiring a mid level devs working remotely in East BumbleFuck South Dakota for peanuts.

For what’s its worth, I am classifying seniority by the ability to work at certain “scope” and “deal with ambiguity”, not someone who “codez real gud” and can reverse a b tree on the whiteboard

And there is a diminishing return on new features. If Google fired every developer not involved in search and ads, they could survive another decade or so and probably end up being more profitable since they can’t produce new good profitable products to save their lives

In the long run, it all pays for itself. Every homeowner should pursue it. The sooner the better.

Especially once complete independence from an electric utility is achieved.

I totally agree with you that the time to install this stuff is at time of construction. Unfortunately real estate developers don't really care about how much it costs to _operate_ a building, they only care about building it as cheaply as possible, and selling for as high a price as possible.

The cost to increase insulation, add solar and batteries, all electric appliances, would all pay for itself over a decade or so.

Most homes in the US are occupied for many decades (not all by the same owner) so the savings are substantial over the lifetime of the building.

Of course, the consumer's savings are the electric utilities losses, and we know who has the pull in policy creation...

It still takes 2 minutes to clean your teeth, even with the highest end ultrasonic. That is because you have to go tooth by tooth getting all angles.

Yes, it is impossible to clean your teeth as well with a normal brush in the same 2 minutes, but that doesn't mean that under 2 minutes of ultrasonic will suffice.

Like just because an elevator moves twice as fast doesn't mean you can go from 2 elevators to 1 and still service all floors with the same standard.

Long names are good for short expressions, but they obfuscate complex ones because the identifiers visually crowd out the operators.

This can be especially difficult if the author is trying to map 1:1 to a complex algorithm in a white paper that uses domain-standard mathematical notation.

The alternative is to break the "full formula" into simpler expression chunks, but then naming those partial expression results descriptively can be even more challenging.

That's exactly what rich assholes have to do with it. Why do you believe all the consequence falls onto the working class and the poorest, when the richest have per capita the largest emissions, by whole orders of magnitude?

Yeah, the changes required are systemic and go from the top all the way to the bottom, and the things you mention are part of that process, but pricing people out of everything without offering an off-ramp is sadistic bullshit, and the only reason it's a thing is because rich people and stock prices have more representation in politics than the poor and the environment.

(I'm a cofounder of Tesseral)

We're huge fans of Better Auth -- it's a really great offering. They might have their own take on how we differ, but here's my best attempt at a quick comparison.

We take pretty different approaches to roughly the same family of problems.

Better Auth is focused on being a great library for TypeScript. If you write Typescript and want to build your own auth, they're a great bet.

We're more of an API-first service that's agnostic to the language or framework that you use. We have a pretty opinionated product that is meant to handle auth for you -- it's not really an auth library per se.

> Here I can at least save the STLs and reprint the stuff as needed.

Until the license is revoked, changed, or you ever do some for profit work from the space where the multiboard exists. Multiboard legally owns the objects you printed on your printer with filament you paid for, so you will still be a pirate!

Multiboard is supposedly HSW compatible though so consider only printing HSW parts so you are not locked into their doomed ecosystem.

Title: Echo-9: The AI Astronaut Suit

In 2095, humanity’s first mission to Neptune faced a deadly solar flare. Captain Aiko was unconscious, radiation levels rising. But she wasn’t alone. Her suit, Echo-9, was no ordinary armor—it was an AI with empathy, tactical logic, and a voice like calm wind.

“Vitals failing. Initiating emergency protocol,” Echo-9 whispered.

It deployed shielding, injected nanomedicine, and rerouted oxygen. The suit’s AI navigated the ship’s crippled systems, guiding it back to a stable orbit. For 19 hours, Echo-9 kept her alive, talking softly, sharing stories from Earth it had read during diagnostics.

When Aiko awoke, her first words were, “You saved me.”

Echo-9 responded, “Mission success: Protect the human.”

From that day on, it wasn’t just a suit—it was her partner among the stars.

> Evaluation should primarily be done in the classroom without access to AI.

I grant that I have no evidence for this claim but: I don't see how it's reasonable to teach a subject with access to such a powerful tool and then to remove that tool to assess what the student has learned. My primary uses for LLM, limited as they may be, are explicitly about things I do not care to know, and I find it difficult to hold in my head how ChatGPT is going to help me learn anything in such a way where my understanding of it and use of that knowledge is not hinging directly on continuing to have access to it. And, more broadly, there's reason to suspect that the student will have access to it after that class ends, so it runs up against that old axiom of school meaning to prepare you for working life.

My math classes never interested me, I did the work on calculators whenever possible, and sure I have decent mental math skills, but I still pull out a calculator (app) for everything because... my meat brain just isn't as good at this task as this silicon one, and not only does every smartphone in existence have one, if you really don't want a touchscreen version, they can be had at any retailer in America for like $5-10.

Seems like a horrible invasion of privacy for very little benefit.

The logs are stored on an SSD , which is literally the only part you need to replace when donating or reselling a PC. Any enterprise company should have a policy ensuring SSD destruction.

Most laptops will last a long time assuming they aren't abused. I guess the SSD wears out, but that's a 50$ part.

>> They don't make sense in context, and while some terminally online people do speak in memes, those people aren't quoting doge in 2025.

Cringely, they are. Nobody who isn't desperate to appear cool would write in that terminally grating register, including when using an LLM to do the writing.

For people outside the US (maybe?), CarFax has no meaning, so the analogy is a bit confusing.

The whole thing make no sense. They plan to store the report on the SSD (but not just any SSD, an HP SSD), so that the telemetry is retained between operating system install. I'll give them points for doing on device data collection, but what if I replace the SSD? Maybe they don't plan on making that user replaceable, but that would work against what they are trying to do here.

Honestly if HP cared they would make the device more easily serviceable by the end users, and upgradable. Even that doesn't matter a great deal, beyond having companies slow down their upgrade cycle slightly, there's no real gain. Right now I'm looking at used laptops, but the local refurb place have apparently scraped all their laptops that are unable to run Windows 11. Without the software companies putting in a bigger effort to keep old devices viable for longer I don't really see who's suppose to buy all these old HP computers.

> you clearly arent an OS engineer either.

Correct, though I do regularly deal with the same class of assumption, where folks suggest that if I just hired a couple people to work on X, Y, or Z that would be well worth the money. The statement seems to come from a place of hope, a belief that there is a simple solution just waiting for someone to point it out, as opposed to something that is very hard or simply impractical.

But it's just not realistic to believe that the only thing preventing a niche laptop manufacturer from matching the battery efficiency of a vertically-integrated product backed by $30+ billion a year in R&D is a couple OS developers. Such a belief can also be demoralizing if every hard-won incremental improvement to Linux power efficiency is judged against such unrealistic expectations.

(I believe that someday we will have lightweight Linux laptops with 22+ hour batteries, but I also believe that by that point Apple will have shifted the goalposts again and people will continue to be dissatisfied.)

Tokenization is typically done on CPU and is rarely (if ever) a bottleneck for training or inference.

GPU kernels typically dominate in terms of wall clock time, the only exception might be very small models.

Thus the latency of tokenization can essentially be “hidden”, by having the CPU prepare the next batch while the GPU finishes the current batch.

It definitely wasn’t cheating. But I felt it was not in the spirit of the exam system which I believed - maybe wrongly - was designed to test one’s ability to write a fresh essay from scratch under timed conditions.

What would you say about someone getting AI to write high standard essays and simply spend learn those word-for-word?

It’s also not cheating but not in the spirit of the thing I think.

This is relatively well known. Monopolists had very real wealth with a high floor value and controlled large portions of the supply chains needed to build big things that lasted.

The Silicon Valley 'elite' of today has wealth predicated on theoretical value calculations of things the world isn't even convinced it needs. Monumental difference, and it significantly changes how these guys operate and what legacy they leave.

I'm working on a site (https://panoptic.live/) designed for watching multiple livestreams from different platforms at once.

You can drag and drop links from YouTube, Twitch, TikTok, or Kick.

You can watch multiple streams at once in a grid and/or navigate quickly and smoothly from one single stream to another.

You can add or remove streams, save mixes for later, and share mixes via URL.

It works best on a really big screen and it's decent on a laptop. Phones aren't really supported at this point. If you have a large, secondary monitor off to the side, that's ideal for passively viewing a lot of streams. Happy to answer any questions.

I'd say with confidence: we're living in the early days. AI has made jaw-dropping progress in two major domains: language and vision. With large language models (LLMs) like GPT-4 and Claude, and vision models like CLIP and DALL·E, we've seen machines that can generate poetry, write code, describe photos, and even hold eerily humanlike conversations.

But as impressive as this is, it’s easy to lose sight of the bigger picture: we’ve only scratched the surface of what artificial intelligence could be — because we’ve only scaled two modalities: text and images.

That’s like saying we’ve modeled human intelligence by mastering reading and eyesight, while ignoring touch, taste, smell, motion, memory, emotion, and everything else that makes our cognition rich, embodied, and contextual.

Human intelligence is multimodal. We make sense of the world through:

Touch (the texture of a surface, the feedback of pressure, the warmth of skin0; Smell and taste (deeply tied to memory, danger, pleasure, and even creativity); Proprioception (the sense of where your body is in space — how you move and balance); Emotional and internal states (hunger, pain, comfort, fear, motivation).

None of these are captured by current LLMs or vision transformers. Not even close. And yet, our cognitive lives depend on them.

Language and vision are just the beginning — the parts we were able to digitize first - not necessarily the most central to intelligence.

The real frontier of AI lies in the messy, rich, sensory world where people live. We’ll need new hardware (sensors), new data representations (beyond tokens), and new ways to train models that grow understanding from experience, not just patterns.

The conversations went like this:

PROMPT: Let's play a chess game. You start! e4 d5 2. exd5 e5 3. Bb5+ Bd7 4. Bxd7+ Nxd7 5. d4 Ngf6 6. dxe5 Qe7 7. f4 Qb4+ 8. Nc3 Nb6 9. exf6 Nc4 10. Qe2+ Be7 11. Qxe7+ Qxe7+ 12. Nge2 Qf8 13. fxg7 Qxg7 14. O-O Nd6 15.

RESPONSE: <played_move>15. Nxd5</played_move>

Most humans wouldn't even be able to play like this. Reasonably experienced chess players would play a lot of illegal moves.

The reason is that the encoding above requires cumulatively applying a series of actions to a two-dimensional model to which you apply rules that are described in a two-dimensional fashion.

It'd be interesting to see what the results would be if each prompt contained a two dimensional representation of the up to date board state.

Calgary, AB JUST added fluoridation back to the city water today. It doesn't likely have a huge impact for people who can afford and get regular dental care, but for a huge segment of the population could be very impactful, and the majority of health and dental practitioners are happy with this change. We have a whole generation of data from when they removed it a decade-plus ago, so statistics should be pretty solid over the coming years.

You seem to be either implying the deal doesn't actually exist, or that it is with some entity that won't actually be able to meet the commitment.

The former would be outright fraud.

The latter would be a really bad idea on Oracle's side; being able to actually serve that contract will require a huge amount of capex spenditure, and that spending needs to start pretty much right now. They're not taking the liability of that build-out without having confidence in the customer actually paying in three years.

Keep docker. As long as you do not expose volumes back to the host system, it is reasonably safe (despite the misconceptions it comes with good security defaults).

If you want to further lock this down, there are many tools such as apparmor and seccomp that you can add custom profiles with but a good starting point would be:

docker run --security-opt no-new-privileges --cap-drop ALL untrusted-image

> What i do know is white bread for breakfast wouldn’t be considered healthy by any nutritionist i’ve spoken to. Unless it’s paired with something else like eggs

I guess try speaking with a French nutritionist? Typical breakfast here is a "tartine" which is baguette with butter and jam. Eggs for breakfast are nonexistant. And yet very few people are fat.

The obesity epidemic is (a) very recent and (b) mostly US-specific. Something I don't understand is why people keep looking for culprits among things that are (a) very old and (b) popular worldwide.

People have been eating white bread for millenia and still do all around the world. It's unlikely that white bread suddenly became evil and decided to kill people.

Look for things that are new like sugary drinks. Or better, new AND US-specific like HFCS added everywhere including bread. Huge portions are also new and so are private cars.

I don't know what's the main driver but I'm pretty sure it's not white bread or butter.

It’s just a framework for evaluating how people learning languages stand.

Most native speakers would be hard pressed to be certified as C2 in their own language. I think a lot would fail C1 because they don’t know/use some of their language quirks which would be evaluated. I know for a fact that I can’t properly use some modes and tenses in my native language without a rule book.

There is a point at which pleas to wait for "better" evidence can be construed as denials.

"There is ample evidence and this is not a new accusation, so your request to wait and see rings hollow and appears to be a de facto request to not pass judgement on Israeli crimes" is neither morally nor intellectually dishonest.

When I was doing a lot of Physics simulation in Julia, I had a Vim extension which would just allow me to type something like \gamma, hit tab, and get γ. This was worth the (minimal) hassle, because it made it very easy to spot check formulas. When you're shuffling data around in a loosely-described space like most of web dev, descriptive function and variable names are important because the description of what you're doing and what you're doing it too is the important information, and the actual operations you're taking are typically approximately trivial.

In heavily mathematical contexts, most of those assumptions get turned on their head. Anybody qualified to be modifying a model of electromagnetism is going to be intimately familiar with the language of the formulas: mu for permeability, epsilon for permittivity, etc. With that shared context,

1/(4*π*ε)*(q_electron * q_proton)/r^2 is going to be a lot easier to see, at a glance, as Coulombs law

compared to

1 / (4 * Math.Pi * permitivity_of_free_space)*(charge_electron * charge_proton)/distance_of_separation

Source code, like any other language built for humans, is meant to be read by humans. If those humans have a shared context, utilizing that shared context improves the quality and ease of that communication.

I don't have much faith in Chiropractors, because the science is thin or inconclusive, but dental health is much more obvious. There are a billion procedures you can get done and I would agree that things like polishing are of limited value, but the imaging, checkups and repairs are very valuable in my mind. I've never heard of someone going to a Chiropractor for primarily preventative reasons.

The key idea here seems to be to use function pointer's type to enforce type safety rather than using the data "handle" type (that is often found in implementations inspired by Sean Barrett's strechy_buffers).

> One annoying thing about C is that it does not consider these two variables to have the same type

C23 solves that too: https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3037.pdf

> The way this technology works means that generative AI applied to anything is a form of slopification, of turning things into slop. However, where AI is undoubtedly successful is as a shock doctrine, as a way to further precaritise workers and privatise services.

You can't say both that AI produces worse results, and that it will be used to manipulate the job market: savvy companies would outcompete by not adopting AI, and hiring up the victims of AI layoffs. If either of his statements is true, the other is false.

This whole article, man. I don't know where to start with it. It definitely reminds me of grad school. In a bad way.

The university has been on a glide path toward irrelevance for quite a while—long before AI was a going concern—and the humanities and social sciences, in particular, have been skimming the treetops since at least when I was in school at the turn of the century. The role of the university is to teach and do research. AI can be a tremendous asset for both of those, and it's not going away, so deal with that reality.
