Getting people to use it is not as hard as you think, unless it’s an entirely new concept. Do more of what works and improves people’s experience, undercut fees from existing contracts. Or make a premium version for that audience segment.
AMMs
Farming
Bridges
Wrapping services
Zapping services (wrapping + amm lp + farming in one transaction)
Yield optimizers (slightly solving issue with LP farming and AMMs)
And if you create a token it advertises itself, bots watch for LPs on AMMs to interact and humans notice the interaction, but another area you can compete is based on how community minded the token is, versus obvious self enrichment
I intentionally chose not to make this a primer on all the acronyms
I also scan the blockchains for certain method signatures of previously popular, which appear when they are invoked. So I find copycat contracts this way, which helps me know about new projects and communities.
Either way to your original question: The time to market is extremely short, the funnel is nearly non-existent with crypto natives, and the overhead costs are lower if you can code - all compared to SaaS deployment or being employed by a SaaS service
