Bolt pitched us a ton (we do eight figures of revenue online using a WP-style checkout), we heard them out, did a small demo-type, and I spoke to a bunch of their customers... and we came to similar conclusions. It's overhyped "technology" that has very questionable marketing claims.
Of course. Everything sucks. But people keep buying stuff and we incrementally improve the experience, so it is what it is.
Our marketing team wanted to move everything to Shopify, and then I asked them to do a cost-benefit analysis compared to the 0% we pay with our current setup (plus Stripe fees).
When the estimate came back in the hundreds of thousands of dollars more per year, I took the opportunity to lecture them on rent-seeking and middleman evaporation of profits that these software startups/businesses capture silently from organizations who just don't do the math.
