This is my first time of hearing Collabstr. - I've had an Alignable account for years (when it was invitation only). I've been on there since earlier this year, and SURPRISINGLY folks still use it. I don't pay a monthly subscription. You can use it as B2B for businesses that you would like to connect with and B2C for potential customers. - bark.com - You purchase credits to get leads. The leads have their profiles set up as to what type of business owner they would like to work with. if the lead doesn't work out, the company will credit you. - Thumbtack - you can create a profile and set your rate for B2B clients. There are handy men and women, movers, photographers, videographers, MUA, etc. - UpWork - You can use it for B2B where other business owners can hire you for services. You can also use it to sell digital products to B2Clike logo package (custom letter head with business colors, etc.) You can set your own rate. The cool thing about Upwork is that it allows you to have one account with two profiles (one for your business and the other as a customer). - Google Business Account - mine is STILL in the infancy stage. You can not only post photos, you can post short/reels type of engagement on your account. you can create a QR code for your business and link it to your Google Business Account. This platform has a whole back office side to it that will be my next project, along with building my UpWork profile. - Yelp Business Profile - I recently received an invitation to create a Yelp Profile. I haven't done it yet. - MailerLite - to utilize the funds for my first min-grant that I received, I purchased a MailerLite account, You can create campaigns, create a sign up page in exchange for email addresses and sell products. This is the project that I am working on now. - Linktr.ee - Linktr.ee has been out for awhile, but within the last year they were campaigning real hard for content creators and creatives to utilize their platform for free. I have a link for my bio and then I have a link for each one of my social media handles. I have seen other creators posts YouTube videos on there, along with having a link to sell products and/or services. - Thinkific.com - I have an account. tony has an account also. you can sell courses on here. There are so many ways that you can use this platform. There is a 2nd-tier project that I will be working on where I will be using Thinkific.
