One submission gives borrowers a coordinated financing process without an upfront brokerage fee.
mosparo's answer
mosparo was founded in May 2021. We needed spam protection for a form on the homepage of a website. Because of data privacy, we wanted a self-hosted solution. So we started to search for spam protection solutions. While there are some solutions, a lot of these solutions use either a puzzle to recognize humans or are built into a system and are not available everywhere.
After some more research, we found that these puzzle solutions do not work for people with disabilities and are, therefore, not accessible. Today, every website should be accessible – but when you have a form, you must decide between accessibility, data privacy, and spam.
Because of this experience, we started to think about a new spam protection system that solves the problems with accessibility and data privacy and is free to use and installable on every regular web hosting.
mosparo – the modern spam protection – was born.
YieldStack's answer:
Rommin Adl and Daniel Chesney founded YieldStack to simplify commercial real estate financing. The platform brings deal preparation, lender matching, offer comparison, and closing coordination into one workflow, combining AI-assisted analysis with human brokerage expertise.
mosparo's answer
The combination of a self-hosted, accessible, and free-to-use solution is not available from other software.
There are a lot of hosted solutions. Some of them are accessible, some not. Some are free, some not. There are also a lot of self-hosted solutions, but they usually use non-accessible methods like guessing characters or icons.
A solution that is accessible, free-to-use, self-hosted, and data-saving is pretty unique.
YieldStack's answer:
YieldStack combines AI-assisted lender matching with hands-on commercial mortgage brokerage. Borrowers submit once, compare financing options, and work with a team that handles structuring, negotiation, and closing coordination. Borrowers approve lender outreach, with no upfront fees and a broker fee paid only at closing.
