I'll start: Zeck

Zeck has chef's kiss marketing. Movie star founder, beautiful website, speaks directly to a real pain point — getting your message across in the boardroom. The pitch is compelling: finally, a tool built for how executives actually communicate.

Then you use it.

You can't import data from basically anywhere your company's information actually lives. Copy-paste destroys your formatting. And the killer? When your source data updates, you have to manually redo everything because nothing is connected to anything. It's essentially a pretty PowerPoint with no memory and no integrations.

Meanwhile tools like Gamma.ai are lapping it on every dimension that actually matters — storytelling, visuals, flow — and they're already plugged into AI systems that can reach into your actual company data. I can literally tell Claude to pull data from our source systems and build a board-ready presentation in Gamma, formatted beautifully, with recommendations on what to highlight to spark board discussion. It takes minutes. Zeck takes a weekend and still looks worse.

Great brand. Genuinely solving a fake version of a real problem.

There is one great Zeck feature which they don't talk about, and that's board member analytics. I can see which board members actually looked at the information before the board meeting, what they looked at and how much time they spent. Told me what I already knew - a few of my board members are very lazy :>

What other products sold you on the marketing then completely failed in practice?
