Another benefit is a 'remind to review elsewhere' message. If the business approves the message, we send a reminder to review the business or product on a service of the business' choice (like Yelp, Amazon, etc.)
I'm hoping that the extremely low barrier to use (sending a text), will mean that these businesses get more feedback (since there are plenty of people who don't want to post on services they have to register for; don't feel like downloading an app; who wouldn't mind giving some feedback, but don't want to feel the pressure of 'crafting' a reply the way you often do on some services; who, even if they are registered, may just put it off forever because it seems like too much work, etc.) and so will have more information with which to improve their businesses. The idea is based on the 'praise publicly, criticize privately' maxim.
I found that most SaaS companies wanted a few really well written and well placed testimonials rather than a constant stream of subpar testimonials and didn't really need a system for that.
It sounds like you may be going more towards local small businesses though and maybe they have a need for it. Happy to discuss any questions further with you if you'd like.
I'm pretty far along with the initial version to demo it to them, so I should have it front of them fairly soon. Dealing with sub-par testimonials is something I thought about early - that's part of the reason everything requires approval by default. I'm hoping these businesses will post the great ones, appreciate, but maybe not post the so-so ones, and take seriously and act on the negative ones.
Ultimately, I'd like it to cohere from three things: a central place to aggregate reviews/testimonials from many sources, a customer feedback system, and a "reminder to review elsewhere" (to nudge the marginal reviewer to actually leave that Yelp review) service rather than just a feedback system like TalkBin or Talk To the Manager.
People aren't wanting for new communications methods. They want what they've always wanted: quick, useful support from someone empowered to provide that.
If I can interact with a business solely through textual communication I will do so, even if it's significantly slower.
TalkBin (YC W11) was a platform for allowing customers to SMS local businesses, but getting brick and mortar businesses to adopt a new communication channel isn't easy.
