I understand that there are many others out there hugely hyped such as Nex, Quarkchain, Sentinal Protocol & these are definitely big multipliers, the contribution & access is tough to get in those ones though. This list is is mainly under the radar that have a working platform ready to go within a few weeks/ months..
Travelblock- Fully functional platform with Resorts, cruises, car rental, flights all paid for with crypto at 30-60% cheaper than expedia by cutting out the hidden fees- 5 ETH investment gets you a free trip anywhere on the platform for 1 week (up to 8 people)
https://www.travelblock.io/HowDoo- A decentralized social media network, another platform that has an alpha available already with a full platform coming soon- If this reaches steemits market cap its a x80 on investment & I believe it could. They aim to stop the privacy issues that you get with Facebook & pay you for top content with 'uDoos'. Top YouTuber Keith Wareing has just put 50k into this.
https://howdoo.io/The Acorn Collective-The Acorn Collective is using blockchain to help founders and startups find access to funding. We provide crowdfunding that is accessible, transparent and more likely to succeed.
It's a huge and growing market in the West and a largely untapped market in most developing countries.
They have recently changed the tokenomics drastically reducing there’s hard cap making the token price very good for some good multipliers on investment.
https://www.aco.ai/A Worker-Aworker is a recruitment platform based on Blockchain with an ambitious purpose to disrupt the HR industry. It changes the way of hiring employees via smart contracts. Aworker will reduce costs per hire up to 4 times and increase people's income. The hiring of personnel is one of the most influential markets in the world, its volume is more than $429 billion.

I know about all four projects - they are all solid ICOs as I see it. Today, I participated in an AMA arranged by the Acorn Collective. Informative and engaging. Good admins in their Telegram group plus regular tweets. A straight forward idea with a decentralized market place for crowdfunding. Not only that, Acorn will have a secondary market place where you can buy services that you have seen on the platform. This means that there is a purpose with their token. It makes sense. There are many ICOs that are money grabs. Acorn is not one of them!
