Building Motion Demo → interactive product demos that update themselves

@rram19000 reddit communities?

[Vinicius Nathan @vininathan]

if you’re into
- saas
- coding
- building in public
- ai/mobile apps

how do you actually validate ideas for your apps?

[Vinicius Nathan @vininathan]

@i_mika_el @X that's a good question
do you run A/B variation tests on your landing page in order to evaluate different variations of ideas?

[Vinicius Nathan @vininathan]

how many ideas have you killed just because the waitlist stayed empty?

if you’re into
- micro-saas
- testing multiple ideas
- not building too early
- real validation

@X do your work

[Vinicius Nathan @vininathan]

@hellyeah_ai hmm it's make sense, do you run this $20 validation on meta ads?

[Vinicius Nathan @vininathan]

@rram19000 totally agree, conversations > landing pages every time

when you do those ‘honest conversations’, how do you usually find the right people without it feeling forced or salesy?
do you go into specific communities, cold DM, or something else?

[Vinicius Nathan @vininathan]

You spent 4 months building.

47 people signed up
3 actually used it
0 paid

This is the default outcome when you skip the "kill" stage

[Vinicius Nathan @vininathan]

@acgfbr esse é o tal do prompt engineering?

[Vinicius Nathan @vininathan]

@leonardoperin8 Tô na mesma dúvida, inclusive, já tem users no teu saas?

[Vinicius Nathan @vininathan]

@robj3d3 Love this project.

While everyone is vibecoding replacements for SaaS tools, the ones that actually survive still need demos that don’t go outdated every time the product changes.

That’s exactly the pain I’m solving with Motion Demo

[Vinicius Nathan @vininathan]

I'm curious how other SaaS founders handle this:

You build a great product, but how do you actually show people how it works?

Do you:

→ Record a video and edit it?
→ Use screenshots/GIFs?
→ Build an interactive demo?
→ Just let users figure it out?
I'm building something in this space and I'd love to hear how you currently do it.

receba a inteligência 🧠

2026 e ainda gravando demo toda vez que o produto muda?

criei o Motion Demo:
grave uma vez, atualize sempre.
→ demos interativas
→ direto no browser
→ sem regravar vídeo

Most developers don't fail because of bad ideas.

They fail because they build alone.

[Vinicius Nathan @vininathan]

Curious question:

Would you build a startup with people you've never met?

[Vinicius Nathan @vininathan]

@UnyaOnX Hello 👋

[Vinicius Nathan @vininathan]

@MonetXpert @X Hi, everyone

[Vinicius Nathan @vininathan]

@guincrf_ @RealGalego @samsantosb @Grimmacez @coproduto cara, acho que o caminho ideal é tocar projetos solo a principio pra pegar a prática dos novos assuntos, depois fica "fácil" trocar de área

[Vinicius Nathan @vininathan]

Random thought:

There should be a place where developers can find startup teams instantly.

#saas #startup #buildinpublic

[Vinicius Nathan @vininathan]

@thunkoid hey!

[Vinicius Nathan @vininathan]

Would you build a startup with strangers?
