I built StartZig — a place to shape your idea before you build anything.
I spent 20 years on the other side of the table, evaluating startup ideas inside an accelerator. Most of the time, the idea itself wasn't the problem — it just wasn't ready yet. Founders hadn't thought through the right things: who the product is really for, what to test first, what an investor would actually push back on.
Over time I realized the hardest and most critical stage is shaping an idea until it actually holds real business value in the market — not just "an idea," but something with a defined edge. Getting there requires three things:
- A structured, professional process to shape the idea, define its added value, and choose the right features for release — moving deliberately from MVP, to MLP, to a beta-ready system.
- Real feedback while the concept is still being built — not after launch. Asking people what they think once the product is already in the market is too late; by then you've already paid the price of guessing wrong.
- A user community built from the earliest stages — so that by the time you're ready to launch, you're not starting from zero.
I built StartZig around exactly these three pieces, so every founder gets this guidance directly, without needing to get into an accelerator first.
What StartZig does:
- An AI mentor that helps you shape and stress-test your idea at every step
- A visual mockup builder, so you can define your product before writing a single line of code
- Pitch practice with virtual angels/VCs that evaluate you like the real thing
- A structured founder community for feedback along the way
- An idea bank, if you don't have a starting idea yet
- Auto-generates a business plan from everything you build
By the end of the journey, you land on a beta invite page — already populated with the users you gathered along the way — and you can invite additional founders straight from StartZig's own community
It's free. If it helps someone take that first step instead of staying stuck at "I don't know where to start," that's enough for me.
Would love your honest take:
If you're pre-idea or early-stage, would something like this actually get you unstuck, or is the real blocker something else entirely?
What's the one thing you wish someone had walked you through before you built your first version?
I like the focus on validating ideas before writing code. Many founders can save months of effort by testing assumptions and gathering real user feedback first.
Curious which part of the validation journey users find most valuable when using StartZig.
20 years evaluating ideas inside an accelerator is your real moat, and it's underused in how you present StartZig. The product is a bundle of features (AI mentor, mockup builder, pitch practice, idea bank, business plan generator), but what makes someone trust it over the ten other "shape your startup idea" AI tools is you, the person who sat on the other side of the table for two decades. Lead with the operator, not the feature list.
The honest tension: your six features pull in different directions. An AI mentor that stress-tests ideas is for people who have one and need it sharpened. An idea bank is for people who have nothing. A business-plan generator is for people near the end. Three different users at three different stages, and a tool serving all of them usually serves none sharply. The strongest version picks one and owns it. Given your background, "accelerator-grade idea stress-test, without needing to get into an accelerator" is the wedge. The rest are features.
To your question: the real blocker for most pre-idea founders isn't structure, it's that they fall in love with the idea and can't hear that it's weak. The thing I wish someone had forced earlier wasn't "how do I shape this" but "should this exist at all, and who specifically is desperate for it." Most tools help you build the idea you already have. The valuable thing is being told, credibly, when to kill it. Your 20 years is exactly the authority that can deliver that message in a way an AI alone can't.
Does StartZig actually tell people their idea is bad when it is, or help everyone move forward? That answer is your whole positioning, because "the tool that tells you the truth" is rare and defensible.
I hear the pitch for "tell people when to kill it," but I'd push back on the premise a bit. There's no stable ground truth for "is this idea good" — even at the VC level, plenty of investors pass on ideas other investors later fund successfully. Same idea, opposite verdicts, both reasonable people.
Facebook itself is a good example — what Zuckerberg ended up building was a completely different idea from what he actually started with. If someone had judged the original concept and killed it early, they'd have missed where it actually ended up.
That's the process working, not a failure of validation. What StartZig actually does is force you through the right questions in a structured way, with an AI mentor and community pushing back along the way. Take something that sounds simple, like "who are your competitors." The answer itself isn't the point — going through that process is what teaches you which features to actually focus on, sharpens what your real added value is, and steers the product in the right direction. That's the mechanism, not a yes/no verdict at the start.
