r/ideavalidation

I’ve been building a little tool called Pre-Mortem that tries to kill your indie project ideas before you waste time building them.

I just put out a trial version and I’m looking for a few people to try it out and give me some feedback.

No API key setup is needed right now — the trial currently includes 1 free analysis per day.

If you have an idea you’re currently considering building, I’d love for you to give it a try!

Any feedback is appreciated!

Hey I am building job search tool, and wanted to talk with job hunters
It will be fully free, just want you to ask questions and join to community

Estoy trabajando hace un tiempo en un proyecto llamado Truly, estudio ingeniería y programo, y llegué a ese punto incómodo donde ya construí bastante, pero empecé a cuestionarme si el concepto central realmente es lo suficientemente bueno.

La idea, simplificada, sería esta:

Imaginate que estás en un bar, una universidad, un evento, una fiesta, un recital, un coworking, etc.

Existe una sala digital temporal vinculada a ese lugar físico.

La gente que está ahí puede entrar mediante un QR, un link o algún tipo de validación por ubicación e interactuar con las demás personas que están en ese mismo lugar.

La idea sería crear una especie de capa digital sobre los lugares del mundo real.

No sería exactamente una app de citas.

Tampoco una red social tradicional.

Sería más algo como:

“¿Quién está acá ahora?”

Dentro de una sala podría haber cosas como:

• perfiles de las personas que están ahí
• publicaciones o mensajes cortos
• reacciones
• encuestas
• interacciones anónimas
• alguna forma de indicar que estás abierto a conocer gente
• contenido temporal que desaparece cuando termina el evento o la sala

De hecho, hice un pequeño experimento para validar si la propuesta generaba curiosidad.

Fui a algunos bares de Buenos Aires y dejé QRs con el texto “Ver personas presentes en el bar”.

Al escanearlos se abría una landing con un botón para intentar acceder. Con un pequeño script medía cuántas personas escaneaban el QR y cuántas además hacían clic en ese botón.

Las métricas fueron bastante buenas, tanto en escaneos como en intención de seguir avanzando, y eso fue una de las señales que me hizo pensar que puede haber algo interesante detrás del concepto.

El modelo de negocio que imaginé originalmente es B2B: que bares, boliches, universidades, eventos, festivales u otros venues paguen una suscripción para tener una red de Truly activa dentro de su espacio.

El usuario final entraría gratis, mientras que el venue pagaría por ofrecer esa experiencia social dentro del lugar: tener su sala oficial, personalizarla, moderarla, generar dinámicas entre las personas presentes y eventualmente acceder a herramientas o métricas propias.

La hipótesis sería que para el venue esto puede servir como una forma de aumentar la interacción entre las personas, mejorar la experiencia dentro del lugar y generar comunidad alrededor del espacio.

Pero justamente una de las cosas que estoy cuestionando es si realmente tiene sentido que el venue tenga que ser quien active la red.

Quizás lo interesante no sea depender inicialmente de venderle el producto a un negocio ? O si ?.

Me sigue gustando mucho el concepto general de crear redes sociales temporales vinculadas a lugares físicos, pero no tengo claro cuál debería ser la forma final del producto ni cuál es el caso de uso más fuerte.

Las preguntas que me estoy haciendo son:

1. Si estuvieras en un bar, evento o universidad y vieras un QR para entrar a una sala con la gente que está ahí, ¿lo abrirías?
2. ¿Qué tendría que haber dentro de esa sala para que realmente quieras quedarte usándola?
3. ¿La sala debería crearla el lugar o debería poder crearla cualquier persona?
4. ¿Ven valor suficiente para que un bar, evento o venue pague mensualmente por tener esta red activa?
5. ¿La idea de una “red social temporal para personas que están en el mismo lugar” les resulta interesante o suena más a una solución buscando un problema?
6. Si tuvieran que reducir todo este concepto a UN solo caso de uso, ¿cuál elegirían?

Cualquier opinión, crítica o idea me sirve muchísimo, especialmente de gente que haya trabajado en productos sociales, comunidades etc

Por si quieren conocer un poco mas del proyecto

Hey guys,

I’d like to share something.

I feel like this is a topic we don’t talk about enough, and maybe it’s actually one of the most important parts of business. Target audience.

It recently crossed my mind, how much time do I actually spend working on my target audience compared to building the product?

Let me tell you a quick story.

There are two people. One is allergic to shrimp, and the other one loves shrimp.

They’re both in different places, but the fisherman doesn’t care where they are. Instead, he spends all his time trying to catch the best shrimp.

But he always drives to the same place, where the person with the shrimp allergy is.

It doesn’t matter how good the shrimp are. The person is allergic to shrimp!

I promised myself that I have to spend more time working on my target audience, so I wrote down the top 5 questions to define a target audience:

1. What problem do they have?
2. What do they want to achieve?
3. Where do they spend their time?
4. How old are they, and where do they live?
5. What have they already tried to solve the problem?

Are these the 5 right questions????

Also, imagine that I’m totally new to business (maybe that’s not too hard to imagine) and give me your best advice on how to define a target audience.

Maybe there’s a great app, program, template, or process that you use to create yours?

Thanks for the advice!

Speak soon,

Jan

This has probably been one of the hardest parts of building apps for me.

Coming up with an idea is easy but deciding if that idea deserves weeks, months or years of development is much harder which makes pain in the a\*\* if no one wants it.

I've been working on a small Android app around this problem. It searches for potential app ideas, helps validate your own ideas against audience/source signals, scores them and lets you keep a shortlist of the ones worth exploring.

The goal isn't really “AI gives you startup ideas.”

It's more like:

Don't start coding until you have some evidence that the problem is worth solving.

It's currently in the beta testing, and I'd love to put it in front of actual builders who would actually use it rather than generic beta testers.

If you build apps/SaaS:

What's the one thing you check before deciding an idea is worth building?

Happy to give beta access to anyone who genuinely wants to try the workflow.

🚀 I'm building a startup and I'm looking for ambitious, talented, and hardworking people who want to create something meaningful.

If you're passionate about entrepreneurship, innovation, and building the next big thing, I'd love to connect with you.

Let's network, exchange ideas, and build something extraordinary together. DM me if you're interested.

i always had this idea, like a chatbot/tool that helps me to understand, solve and "think" in first principles (yeah the one elon musk uses and talks about)

so as i was learning RAG, i got to implement this idea

i basically,
- fetched 20+ data sources from interviews of musk, articles about feyman etc
- chunking, embedding them in supabase (pgvectorDB)
- retrieve the relevant chunks and augment them (RAG)
- use LLM to generate the final answer, resulting in much grounded answers

i implemented it as a fun project, what do u think, is it worth it to deploy it as a product?

Hey there👋

I've been working on iPayThis — a marketplace that flips the traditional model. Instead of sellers setting prices, buyers post what they need and the maximum they're willing to pay. Sellers then compete by bidding lower.

It's live at ipaythis.com

Here's the core idea:

You need something done. You post it with your max budget.

Service providers see your request and submit offers at or below that price.

You pick the best offer. Payment goes into escrow. Done.

I also added a Business Directory where verified service providers can list their business and receive direct private quote requests from buyers who aren't sure what something should cost yet.

Would genuinely love feedback — what's confusing, what's missing, what you'd want as a buyer or seller. Roast it, I can take it.

I’m exploring a Personal AI Agent that can do more than just answer questions. The idea is that you tell it what you want, and it helps you research, compare options, and complete tasks across things like shopping, travel, bookings, and recommendations.

For example:

“Find me the best laptop under ₹60,000.”

“Plan a 3-day trip to Goa under ₹15,000.”

“Compare these products and tell me which one I should buy.”

I’m not building it yet. I want to validate whether this is actually a problem worth solving.

Would you use something like this?

Yes — I’d use it regularly

Maybe — depends on the features

No — I don’t see the need

If you vote, please also tell me what you would actually want this agent to do. Critical feedback is more useful to me than compliments.

I’ve been thinking about how many freelancers, consultants, solo founders, and tiny agencies technically need a CRM but absolutely hate using one.

Most CRMs seem to grow into the same thing:

• 40 different fields
• Sales pipelines
• Automations
• Lead scoring
• Reports
• Integrations
• A dashboard that looks like you're running Salesforce for a Fortune 500 company

But a lot of small operators really just need to remember:

Who is this person?
When did I last talk to them?
What did we talk about?
What am I supposed to do next?

So the idea is an intentionally tiny CRM.

Add a person/company, write notes, set a next action, and move on.

The app would automatically build a timeline of your relationship with them:

• First contact
• Emails/meeting notes
• Quotes or proposals sent
• Follow-ups
• Important context
• Next action

The main screen wouldn't be a giant sales dashboard.

It would basically say:

These are the 7 people you should probably talk to today.

Maybe AI could summarize long histories or suggest follow-ups, but I'd specifically avoid turning "AI CRM" into the selling point.

The entire pitch would be:

>

My concern is obvious: there are already approximately 9 billion CRMs.

So roast it.

Is simplicity actually enough differentiation here, or is this just another stripped-down CRM that eventually adds features until it becomes the thing it was supposed to replace?

And if you currently don't use a CRM even though you probably should, why not?
