Too many founders don’t fail because the product is “bad.”
They fail because they mistake polite interest for real demand.
In this episode of #StartupsUnedited, I sit down with Ellen Rubin, Operating Partner at Glasswing Ventures - multi-time founder (CloudSwitch → Verizon, ClearSky Data → AWS) and former marketing Netezza leader - to break down the hardest transition in startups:➡️ “Nice-to-have” → “Must-have”…and how to prove it before you waste years building.
What you’ll learn (no fluff):
How to tell if strangers, not just your network, actually want what you’re building
Why “That makes sense” is the most dangerous feedback a founder can hear
The real question founders avoid: are customers actually in pain right now?
The uncomfortable test: can anyone besides the founder sell it?
Time-to-value in enterprise - why you must show real value in the first 5 minutes
Pricing traps: why cheap revenue creates false positives and poisons roadmaps
What VCs actually look for now: velocity to revenue + workflow stickiness (not “cool AI”)
Why vertical AI and end-to-end workflow ownership is where the next giants are built
If you’re building B2B, enterprise, AI-native, vertical AI, or infrastructure, this is a masterclass in signal vs. noise.
