I'm building a better way to make startup decisions
My weekend hobby is prototyping ideas.
I usually come up with a story, design a small brand, build an MVP, deploy it to Vercel, and then let it sit for a few weeks while I decide whether it's worth pursuing or leaving behind.
The main goal isn't to launch a startup every weekend. It's to learn, experiment with new tools, or simply scratch the itch of building something that came to me in the shower.
Last weekend I started working on an idea I'd like to validate.
It comes from a very real problem in the way I work. I'm a solo founder, so I don't have a team of specialists to discuss important decisions with. Most of the time I end up talking to ChatGPT or one of its cousins.
The problem is that, after spending so many hours using these tools, I already have a pretty good idea of what they're going to say depending on how I phrase the question. Sometimes I can even steer them toward the answer I want just by pushing a little harder.
That's where BuildersBoard comes in.
The idea isn't to build yet another AI chat. It's to build a decision-making system for startup founders.
The advisors represent different disciplines and follow a process inspired by Lean Startup. Their job isn't to validate your ideas. They challenge assumptions, ask for evidence, and often suggest the next experiment instead of giving you an immediate answer.
Many times that means leaving the conversation and doing actual work: interviewing potential customers, testing a different pricing strategy, running an A/B test, or validating a hypothesis before moving forward.
And that's the part I'm most excited about.
What each advisor says isn't the most important thing. What matters is how decisions are made and what happens afterward. Every decision is linked to the evidence that supported it, the experiments that were run, and the reasoning behind it. Over time, the project builds a shared decision memory that explains not only what was decided, but why.
I honestly don't know yet whether this solves a real problem or if it's simply an interesting idea. That's why I decided to publish the landing page before finishing the product and start talking with other founders.
If you have a couple of minutes, I'd really appreciate your feedback on the idea and the value proposition.
The part about being able to steer ChatGPT toward the answer you already want is a real tension.
BuildersBoard seems to start from a different premise: the value of a decision process isn’t necessarily the quality of the answer it produces.
Exactly. That's a great way to put it.
I think the value isn't in finding the "best" answer, but in improving the quality of the process that leads to a decision.
The advisors aren't there to replace judgment. Their role is to challenge assumptions, ask for evidence, suggest experiments, and make sure important decisions aren't based only on intuition.
If the outcome is simply "here's the answer," then it's not very different from a chat. What I'm trying to build is a system that helps founders think more rigorously and preserves the reasoning behind those decisions over time.
Thanks for sharing. I hope you register to get quick access to the beta :P
That distinction is what caught my attention — preserving the reasoning behind decisions is a very different problem from simply generating answers.
I'll keep an eye on how the beta develops. Interested to see what patterns emerge once founders start using it in real decisions.
I appreciate that.
That's exactly the hypothesis I want to test with the beta. I'm less interested in whether founders agree with the advisors, and more interested in whether the process changes the way they make decisions.
If, after a few sessions, founders are asking better questions, running better experiments, and documenting the reasoning behind their decisions, I'll consider that a much stronger signal than simply getting "good advice."
I'm sure I'll learn a lot once people start using it on real projects.
I appreciate you explaining that. The distinction between getting answers and improving the decision process itself is what makes the idea interesting.
I’d like to continue the conversation outside the thread. What’s the best email to reach you on?
Thank you! I really appreciate that.
I'd be happy to continue the conversation.
You can reach me at rubendariogimenez@gmail.com
I'd love to hear more about how you make strategic decisions today and get your thoughts on where BuildersBoard could provide the most value.
Thanks! I’ve just sent it over.
Looking forward to hearing your thoughts whenever you have a chance.

The part about keeping a decision memory with the evidence behind every call is what stuck with me. Most tools remember the conversation. Very few remember why a decision was made.
This also feels like something that could naturally be getting a lot more organic traffic than it probably is already. When you're still figuring out if the idea has legs that kind of signal becomes really valuable.
Did anything make you start thinking that too?
Honestly, yes.
When I first built the landing, the focus was on the AI advisory board. After sharing it, several founders pointed out that a panel of AI advisors isn't that hard to recreate with good prompts.
What kept coming up instead was the decision memory: preserving the reasoning, the evidence, the experiments, and the context behind each decision.
That made me realize I was emphasizing the mechanism instead of the outcome.
The advisors are important, but they're really the interface. They help make the Lean Startup process feel natural by guiding founders through customer interviews, experiments, pricing validation, and evidence-based decisions instead of simply giving answers.
The real product is helping founders make better decisions and building a knowledge base of why those decisions were made.
That's the direction I'm exploring now, and the feedback has definitely influenced how I'm thinking about the product.
I think that's the right direction. Reading your post and your reply, I noticed a few organic search opportunities that could help BuildersBoard reach founders already searching for this kind of solution.
If you're curious, feel free to reach out at mumar [at] growwithmumar [dot] online. Happy to share a few ideas—no pitch, just observations.
Thanks, I really appreciate that.
Organic search is definitely something I haven't thought much about yet, so I'd love to hear your perspective.
I'll reach out. Thanks for offering your insights!
