YC deadline in <2 weeks; Who's applying?

by‱

If you're applying, reply below with what you're building so we can cheer you on!

If you're doing a startup and not applying, why aren't you applying?

If I were starting a company today, I would 100% apply even though I've done it before with @Tandem (S19) for a few key reasons:

  1. The partners help. A lot. (this isn't common. Most people who say they help startups are neutral or harmful)

  2. The network is insane, especially for b2b companies. It will accelerate your G2M like nothing else.

  3. You'll learn what real speed looks like, by grinding alongside the top early stage founders. Every time I talk to a current or recent YC company or go to the events, I'm reminded what top speed looks like. And I'm also reminded that the speed that start-ups are capable of gets faster every year, especially with AI.

As for hesitations...sometimes people balk at the dilution, but generally speaking, the higher price that startups command in their next round at Demo Day more than compensates.

🚀 We’re applying!

Tech By Tech Agents: The Global AI Agent Store – the first curated, specialist-powered AI agent marketplace built in Africa for the world.

Unlike typical AI “bot stores,” every agent is co-built or validated by real experts (doctors, lawyers, engineers, etc), fully exportable (web, WhatsApp, app, more), and standards-driven (we’re launching TAML: Tech By Tech Agent Markup Language).

We believe the next wave of AI is about trust, jobs, and real-world results.

Building our team, raising, and aiming to set a new global standard for useful AI.

@juvenal_lunguenda That's a lot of buzzwords. I'd suggest really distilling what you're building into plain English. Also, how do you know people want this? I've talked to a few marketplaces for agents, and I'm always a bit skeptical. Most people aren't really using agents. So why would people want a marketplace for agents?

Juvenal Carlos Lunguenda

@rajiv_ayyangar 
You're absolutely right about the buzzwords, Rajiv, thanks for that reality-check. Let me cut straight to what we actually do.

We help people get professional work done using tools built by real experts. Think Uber, but instead of drivers, you get verified professionals—doctors, lawyers, engineers, teachers, architects, translators, and more—who’ve turned their expertise into practical AI tools.

‹
You asked how we know people want this - here's the proof:

  • Paying users across 40+ countries in just a few months

  • 80% come back and pay again - that's not hype, that's real value

  • Real companies like KixicrĂ©dito (microfinance company in Angola) are choosing our tools for onboard document validation instead of hiring more staff

  • Our Arabic translator gets heavy daily use from Middle East professionals - and we don't even speak Arabic ourselves

  • Top construction companies like NSDC - Novas SoluçÔes de construção in Angola is co-creating with us by giving us ongoing feedback to improve our imagery tools

    ‹Our marketplace works because we believe no single company can build useful AI for every real-world need:

  1. Users get expert help without expert hourly rates

  2. Experts create a new digital income stream from their knowledge instead of just trading time for money

  3. Trust is built in - you know exactly which professional built each tool

And yes, you should be skeptical about marketplaces - most are tech solutions looking for problems.

But when a microfinance company chooses our tools to boost their team’s productivity—without needing to hire more staff, and professionals use our translator daily instead of other options, that's market validation you can verify.

‹
We know it's early days and there is a lot to prove, but we're building for real jobs and results, not hype. Always open to more critique and suggestions as we grow.

Matt Carroll

@juvenal_lunguenda if im being blunt it feels like your response is AI slop and i was hesitant to read it for that reason alone.

Your social proof does seem strong, but i feel like you could have done a 10x better job at convincing me to care with 10x less words.

congrats on building and shipping! and esp on having paying customers!

just 2c from a random guy in the comments section

Juvenal Carlos Lunguenda

@catt_marroll  You're absolutely right, Matt. That was invaluable, blunt feedback – exactly what we need. We clearly missed the mark on conciseness, and "AI slop" is a fair call for that length.

Thanks for acknowledging the social proof. Point taken on the "10x less words to convince." We're learning to distill.

Really appreciate your support. Your 2c are golden!

Raja Tayyab

@juvenal_lunguenda Really interesting to see so many founders applying to YC and pushing their ideas forward. What stands out is how authenticity and real-world validation matter more than just buzzwords. It reminds me of how people talk about Real muha meds in the vaping space — the focus isn’t only on the name, but on actual quality, trust, and the experience users get. Whether it’s startups or consumer products, the real value always comes from delivering something genuine that people truly want.

Aurélia Bret

Hello @rajiv_ayyangar We are applying to YC with @Intlayer !! 🚀

Multilingual content infra for devs that started as a CLI, now expanding into a full content platform with React, Vue, Vite, Next, Nuxt, CMS sync, AI autofill and 200+ languages.

We've been dreaming of YC for a while. We're super excited (and a little stressed 😅) to finally take the leap.

@aymeric_pineau built it solo at first, now we’re a little team building it together đŸ’Ș

To the moon !! 🚀

Dan Bulteel
Will apply with Meet-Ting, free AI assistant for email scheduling - made for founders, consultants, freelancers and small business owners - anyone where meetings aren’t just get-togethers, but sources of deals and income. We strongly believe email and AI is an upgrade to current link-based calendar tools for many reasons (dynamic not static, more guest friendly, no interface hopping from inbox to web etc.), and feel the pitch is finally strong enough for YC consideration! It will also be one week after our closed beta launch by time for application, so hopefully with some more strong user validation and feedback to punch up the case.
Rajiv Ayyangar

@dbul Scheduling is a holy grail problem with a large graveyard. Huge if you can crack it. How well does it actually work?

Dan Bulteel

@rajiv_ayyangar For 1:1 meetings, Ting can handle:

‱ Direct booking (e.g. “Ting, book me and Guest at 2pm on Tuesday”)

‱ Scheduling (e.g. “Ting, find a time with me and Guest next week”)

‱ Rescheduling (e.g. “Ting, that time doesn’t work anymore” - from either side)

‱ Canceling (also works from either side)

When both users are on Ting, we unlock a neat network effect: instant booking. No emails needed - Ting syncs server-side and picks the best time based on both calendars and preferences.

Current bugs we’re navigating:

‱ Inbox setup edge cases (Gmail only for now)

‱ Handling vague replies that trip up the AI

Post-closed beta, we’re focused on:

‱ Opt-in memory to reduce user effort and improve preference recall

‱ Richer context inputs for smarter, more human scheduling

‱ Multi-guest booking (our “calendar nirvana” if all users are on Ting)

We’re launching here next Wednesday - would love your feedback!

Yunaweo

@rajiv_ayyangar  @dbul Reading through everyone’s YC applications here reminds me of how founders like Kiki Abdul Rachman Benyamin approached growth — starting small, validating with real paying users, then scaling through strong community and partner networks. It’s a good reminder that traction and trust often speak louder than pitch decks, especially when you’re building for real-world impact.

Dan Bulteel
@dbul @rajiv_ayyangar If you are up for testing quickly, email: schedulingvictims@this-ting.com
Julia Yu

@dbul Super interesting — scheduling is one of those “graveyard problems” where the winners usually have two things:

Curious: how much real-world usage you’ve already seen? Not beta signups, but actual end-to-end meetings successfully booked, rescheduled, canceled, etc. YC (and investors in general) usually look for behavioral validation, not just feature completeness.

Inside Unicorns Club we see this pattern across many tools:

the moment teams get even 20–50 weekly active “real” users (not friends), retention tells the whole story.

How’s it looking on your side today? Any early retention or repeat-usage signals since launch?

Dan Bulteel

@juliayugo 100 per cent, a lot more since applied last time around! Scheduled close to 1k meetings, core users book about 20 meetings per month, and still not done any marketing!

Axel Brunet

Hey 👋,


I’m applying to YC (Fall 2025).

I’m building Aelya, a vertical AI co-pilot for solo doctors. It auto-writes medical notes, fills forms, and saves hours of admin per day.


Most doctors in Europe waste 2–3 hours daily on documentation. Aelya gives them that time back without changing tools, and fully GDPR-compliant.


I burned out twice so I know how bad it gets when medicine becomes paperwork. That’s why I’m building this.


MVP is shipping soon, already talking to potential early users in France.

Faridat Folake Ojulari

@axel_brunet This is lovely! I messaged you on LinkedIn to discuss a potential collaboration.

Rajiv Ayyangar

@axel_brunet Amazing, good luck. This is such an incredibly valuable problem. Sounds like you're building a product for yourself, which is a great way to approach a startup. I don't know how it is in Europe, but in the U.S., building tools for medical professionals often requires some creative solutions for getting into market. How easy is it to get MVPs into the hands of customers?

Axel Brunet

Thanks @rajiv_ayyangar , you’re 100% right !

Getting into the hands of doctors can be slow and painful, especially with hospitals and big EMRs. That’s why I’m focusing on independent solo doctors first.


In France (and much of Europe), most are fully autonomous: no IT approval, no procurement, no red tape. If the tool saves them time, they will try it.
However, reaching them at scale is tricky: no obvious channel, fragmented market, and most are overworked.

So I’m testing personnal outreach and small medical communities.

My MVP is built with that in mind:

– no install, no login

– works with their current setup (email, PDF, etc...)

– first test with a podiatrist in August → SOAP notes generated live during consultation

– then scale through small networks + medical resellers


It’s still early, but I'm trying to keep the process frictionless, both product and GTM-wise.


Thanks for highlighting it.

Would love your thoughts if anything feels off.

Julia Yu

@axel_brunet interesting! do you have a co-founder? do you have a clinical background, medical degree, or experience inside healthcare systems?

In our data at Unicorns Club, investors tend to look for two things specifically in products like this:

  1. credible domain expertise (someone who deeply understands the medical workflow, regulations, documentation patterns),

  2. a team, not a single point of failure — especially when the product touches compliance, safety, and high-stakes decisions.

Your story about burnout gives a strong “why,” but YC and early investors often ask who complements the technical side and who ensures the product matches how doctors actually work day to day.

Gijs van Dijk
We’ll be applying for F25 with Caught (An AI-powered news app that brings together different sources into one clear, unbiased and factual summary, so you get the full story without the noise). We’re still early, but this would be a huge boost for us. We’re launching soon on Product Hunt for those interested.
Rajiv Ayyangar

@g888 News is such a tricky consumer space, but can be big if done right. I had high hopes for @Artifact . Do you have a sense of what happened to them?

Gijs van Dijk

@rajiv_ayyangar Prior to starting this I read a Failory article on how they lost a lot of traction by starting to take a too broad approach and pivoting away from being just a source for news. They became too social-media-esque (if that’s a word) by adding things like user generated content and a more Twitter like feed. Though my take on why Artifact failed is that they were focusing on the wrong audience. They focussed on younger generations (16-21) which is not an audience that’s as much interested in reading the news.

I've heard so much about YC and often watch YC's YouTube videos. The vibe of building something alongside great mentors and a strong alumni community really excites me.

I do wonder if there might be online batches in the future? I know YC has always been in-person and requires staying together for 3 months, but I’d be thrilled if there were ever a remote option too.

Rajiv Ayyangar

@victoria_wu You should apply! I think with the community and general vibes of San Francisco, it's well worth moving to SF for three months. Garry in particular has been really intentional and effective at creating community in-person.

J T
Applying with my devtool, vartiq.com What do you think? Is there any chance we can make it?
Matt Carroll

@jonayed_tanjim 

Mega nit but your first card is larger than the others!

J T

@catt_marroll thanks man! We just figured it out. Updated đŸ«Ą

Rajiv Ayyangar

@jonayed_tanjim I'm not close enough to Webhooks to understand if this is a valuable problem to solve. But if this is a common build vs buy decision, my general feeling is that all of these decisions for Dev/Infra will move towards buy. Do you have customers yet?

J T

@rajiv_ayyangar Yes, we currently have a few customers in our private beta, and we’re onboarding two YC companies soon.

On the problem side: it’s a real pain point that surfaces as companies begin to scale. Webhooks often start as a “just make it work” thing, but quickly become a reliability nightmare when the product demands more attention.

Our mission is simple: Stripe’s webhook reliability is legendary. We’re bringing that level of infrastructure to the 99% of teams who can’t afford to build it in-house.

Matt Carroll

honestly this is pretty cool! i use stripe and indeed am always impressed (esp with their testing / debugging sandbox). i can imagine you finding a nice niche to fill here, hope it works out for you :) and keep posting about the voyage as you go!

J T

@catt_marroll Hey man! Thanks a lot. This is really inspiring! We're grinding hard.

Julia Yu

@jonayed_tanjim how do you think about the market size and the growth story here?

Inside Unicorns Club we see a lot of tools that developers love, but YC and most venture investors usually look for something slightly different:

a clear path from “useful tool” → large, fast-growing market with expansion potential.

Right now Vartiq feels like a tool, but I’m trying to understand what turns it into a venture-scale company?

Your execution looks great — I’m just wondering what the bigger arc of the story is.

Daniil Okhlopkov

Why do people still care about YC and venture funding at all? The success rate of building a successful startup is miserable—founders often trade ~4 years of their youth for the 'experience'. I worked at two VC firms; their business model thrives simply because they have a large number of shots.

Chris Surita

@okhlopkov subjective experience, a lot of people I know who have gone on to start their own gigs went to YC just for visibility and it absolutely helped them. Some investors just want that orange badge on your page.

Also people absolutely realize the chance of success is low, but thats regardless of YC for a startup. When you're building alone or in a small team, it's a very small and special class of person (and I mean this in a very positive way) who can wake up and say "this is it".

YC is the hypeman for so many startups, and sometimes people need that to keep going.

----

Second side note, I've seen successful startup founders tell their protege's to apply to YC. Not to get in or anything, but solely as a humbling experience when they don't. There's so many reasons that an institution like YC matters in my opinion, and it's not solely just to have people get in. If thats peoples reasons for applying then yeah, I agree, this isn't the way to go about things.

Tom Ideaxton

Hello. Do you think it is worth submitting my project if I am from Ukraine and cannot travel to the United States?

I can't say for sure that my project will be selected, but if it is, would it be possible to collaborate online?

YC has been my dream since 2018, but I am apprehensive 😁

Rajiv Ayyangar

@ideaxton I'm not sure. They might have something on their site about it. They also might have some ways of helping you get over here. I think it's worth applying at the very least. The application has a good set of questions to ask yourself about your project.

Tom Ideaxton

@rajiv_ayyangar thank you 🙏

Shashwat Verma

Need suggestion here.

We are not sure if we should apply. We are a team of ex-YC founders but don't have a product ready just yet. We are working hard to launch before application deadline. Our concern is that we won't have enough data to talk about it during the interview. We will apply anyway. But what can we do to improve our odds of selection. Any suggestion will help.

We are building Cursor for design - Rustic AI.

Rajiv Ayyangar

@shashwat_verma2 Yeah, I'd apply anyway. My general thinking is that the number one thing you can do to improve your odds of selection is also the number one thing you can do to make progress on the product. For example, it could be getting early user interviews or de-risking the number one risk.

Julia Yu

@shashwat_verma2 Totally agree that you should apply — teams with prior YC experience usually get evaluated on a different axis (clarity, velocity, and depth of insight).

YC doesn’t actually need “a lot of data,” but they do need evidence that you understand your problem better than anyone else.

But, anyway, at the earliest stage, YC (and most investors) look for signals, not fully polished products. Strong signals can be:

‱ a tiny cohort of real users who return (retention > features),

‱ even a small amount of revenue or clear willingness to pay,

‱ LOIs from teams who strongly want what you’re building,

‱ a sharp insight from problem interviews that others don’t see,

‱ a strong founder background (exits, deep domain experience). — YOU HAVE IT!

I guess, if you have at least one or two of these before the interview, you’re already ahead of most applicants.
