Hi Reader,

Welcome to Hal9 Weekly — insights from our founder Javier on turning AI ideas into real products.

Javier's Insights:

SaaS Is Dead. Personalized Software Is What's Next.

Right now, if you need a CRM, you go search for one. You compare 10 options, sit through demos, and still end up with something that's 70% of what you actually need.

That whole model is about to break.

When the cost of building software approaches zero, you stop searching for solutions — you start building them, or having someone build them for you.

Here's what I think the next big software business model looks like:

You get an email that says: "Hey, I looked at your LinkedIn, understood your business, found your pain points, and built you a custom tool. Here it is. Try it. $50/month if it works for you."

No discovery calls. No demos. Just a finished product built specifically for your problem.

That's where vibe coding actually leads — not more SaaS options, but personalized software sold directly to the person who needs it.

Tool fatigue doesn't get solved by better search. It gets solved by someone building the right thing for you from the start.

Wild time to be building.

Do you think we're heading toward personalized software, or will big platforms still win?

Customer Success Story: Propio

From Financial Data to AI-Powered Insights — In Weeks

Propio is on a mission to empower accounting firms by streamlining low-margin tasks so accountants can focus on high-value services. Their platform helps small businesses simplify complex financial processes — but they needed to take their reporting to the next level.

The Challenge: Small business owners often lack the expertise to interpret traditional financial statements. Propio needed a custom AI solution that could analyze financial data and generate clear, plain-language insights — all while integrating seamlessly into their existing platform. Speed was critical.

Hal9 helped Propio:

☁️ Launch a secure, cloud-based API integrated directly into Propio's reporting tab via simple bearer token authentication

🔄 Iterate rapidly through weekly syncs, ensuring the solution stayed aligned with Propio's evolving needs

The result? Propio's accountants can now generate AI-powered financial insights effortlessly within their existing workflow — enhancing client satisfaction and positioning Propio as an innovator in accounting technology.
