Hal9 Weekly Roundup: Why we turned down a $200K MVP, and Greeny's Carbon Credit Demo


At Hal9, we help Startup Founders turn AI ideas into products—fast. Each week, we’ll share insights from our founder Javier, spotlight real customer stories, and keep you updated on what’s happening at Hal9 and beyond.

Javier's Insights of the Week

Javier shared some great insights on LinkedIn this week, including:

Scaling Beyond Bottlenecks
Growth stalls when people—not platforms—become the constraint. Javier highlighted how Hal9 is tackling its own delivery bottlenecks, measuring success by how many new customers the team can serve each month while keeping churn low.

Why MVPs Should Feel Uncomfortable
A founder offered $200k for a “perfect” MVP. Javier’s advice? Don’t do it. An MVP is supposed to feel raw and a little scary to ship. It’s better to invest in many small iterations than to blow the budget on one big bet.

The $50K Rule of Thumb
If he had to start over with just $50k, Javier would split it evenly: half to go-to-market, half to product. That balance keeps founders from over-investing in either tech or marketing. At Hal9, the focus is on stretching that product budget into a scalable MVP—fast.


Founder Spotlight: Greeny

🌍 Building a carbon credit demo in just two weeks

Greeny, a startup reshaping carbon credit markets, needed to impress customers and investors—fast. Their challenge: deliver a functional, scalable AI solution to compute carbon credits with speed and accuracy.

Hal9 helped Greeny:

  • 🚀 Develop an AI-powered carbon credit demo in just two weeks
  • 🔗 Integrate emissions and offset data into a tailored AI model
  • ☁️ Deploy as a cloud-based API with an interactive demo interface

The result? Greeny went from concept to investor-ready product faster than ever, accelerating fundraising and customer acquisition while positioning themselves as a leader in sustainable tech.
