MVPBuilder.io VS SplitBiller

MVPBuilder.io's answer

Developers with a full-time job and a side project that has been almost done for months. Not beginners, not people looking for someone to build it for them. The requirement is that you own the implementation and can put three to five hours a week into it, spread across several days rather than in one block.

SplitBiller's answer:

People who split expenses occasionally, not habitually.

MVPBuilder.io's answer

The milestone is enforced, not tracked. On day 13, 21 or 30 you attach a URL or a file, and a person reads it against a goal that was written down before day one and frozen. No proof, no continuation: the sprint pauses. Everyday check-ins stay voluntary on purpose — the point is not attendance, it is that something exists at the checkpoint.

SplitBiller's answer:

SplitBiller helps friends split bills instantly — no apps, no accounts, no friction.

MVPBuilder.io's answer

AI will give you a plan in ten minutes and will not notice when you skip Day 4. What is missing is not another plan, it is a checkpoint someone else reads. The daily prompt is calibrated to your own project context rather than generic advice, and the decision to take you on is made in a call, not by a form — vague scope gets turned down there, because a sprint that starts wrong produces nothing worth showing.

MVPBuilder.io's answer

I built the enforcement first and then ran it on myself: a 21-day sprint as a participant, with the goal written down and frozen before day one. I missed one of my four criteria and published that alongside the three I met. The product exists so that every participant gets the same setup: a goal frozen before day one, and proof at each milestone that a human reads.

SplitBiller's answer:

I built SplitBiller because splitting bills shouldn’t feel like a task in itself.

I kept running into the same annoying scenario:

Someone pays the bill,

Then the group spends 5–10 minutes figuring out who owes what,

Someone suggests an app,

Someone else doesn’t want to install anything,

Then someone inevitably forgets to do it later.

I tried the big apps — they’re great for tracking long-term shared expenses, but for one–off splits they felt like overkill — signups, accounts, reminders, group setup, notifications… all for something you just want done right now.

So I thought: What if it were as simple as opening a page, entering the amounts, and sharing the answer? No accounts. No history. No friction.

That’s exactly what I built.

SplitBiller isn’t trying to replace full-featured expense trackers — it’s for the moments when all you need is fast math and a shareable result.
