Back in 2018, I quit my cryptocurrency exchange job to build TxBatch, a bulk search blockchain explorer. It worked... kind of. We made the product, partnered with the right people, got the help we needed - but we couldn't sell it.<p>We did, at least, get in touch with the top cryptocurrency exchanges and hear directly from them that they didn't need it.<p>As for failure reasons, I think it's:<p>1. A blockchain bulk search engine simply isn't as sorely needed as I predicted. Should have pre-sold it (even if I wasn't sure if it was possible to make)<p>2. It was built to scratch an itch I <i>remembered</i> at my old job, but that same company I worked for was likely an outlier (they've now gone bankrupt). Should have met a specific user and designed it exactly for them.<p>3. I focused on development far too much over the rest of the business (and as the only full-time member of the startup, that had a big effect...). Should have focused more on partnerships, marketing, and sales.<p>We're now creating SatSearch, which is a universal blockchain search engine.
