WhenHub – WHEN ICO Timeline Marketing Studio Interface Network?

WhenHub is a blockchain-based smart contract technology that connects people for business transactions online or in-person. Find out how it works today in our review.

What is WhenHub?

WhenHub, found online at WhenHub.com, is a mobile app that aims to connect consumers to experts using two-way video streams, text conversations, audio calls, or in-person meetings. The app is currently in development.

WHEN tokens went on sale on October 26, 2017.

The app will be part of a larger ecosystem of services called the WhenHub Interface Network, or WIN. That ecosystem will consist of decentralized apps (DApps) running on the Ethereum blockchain to create secure micro-contracts. Altogether, the ecosystem aims to solve problems among consultants and clients.

Let’s take a closer look at how WhenHub works and how it plans to change the online marketplace for expert services and consulting.

How Does WhenHub Work?

WhenHub is built on the Ethereum blockchain as part of the WhenHub Interface Network (WIN). WhenHub uses smart contracts – including “secure micro-contracts” – to facilitate interactions between users.

These micro-contracts can be as short as 15 minutes. The blockchain will be used to provide a frictionless billing and payment service.

At the end of each micro-contract, payment will be delivered in the form of WHEN tokens. Tokens are automatically transferred to the expert in question. No paperwork or billing is involved in the process.

Users, meanwhile, can buy WHEN tokens using a credit card or existing cryptocurrencies.

The user’s phone number and address are never shared with experts. Meanwhile, WhenHub will partner with third parties to provide verification services on participating experts to give consumers confidence.

Pricing for experts can be fixed or based on an auction-like system. Experts can display their availability whenever they like – even for windows as short as 15 minutes. This allows experts to monetize their spare time through a competitive marketplace.

A key part of the ecosystem is the WhenHub API, described as “our all-encompassing engine for time-based information” in the WhenHub whitepaper. The API provides integration with many popular services, including Google, Apple, Microsoft, and third-party calendars.

WhenHub Studio is another key feature. WhenHub Studio is the platform’s web-based time curation and publishing platform. The platform makes it easy for anyone to organize events from the past, present, or future into schedules, and those schedules can be published online in the form of “Whencasts”.

Each Whencast is an interactive, mobile-friendly visualization that can be posted onto a website to help visitors process information more easily.

Finally, there’s WhenHub Approach, a mobile app for geostreaming and geofencing. Using the WhenHub Approach app, the company can track multiple people as they travel to a meeting, then use geofencing to determine their relative proximity to one another. Approach also has an underlying REST API that uses WebSockets for real-time multi-user updating and syncing.

What Problems Does WhenHub Seek to Solve?

WhenHub aims to solve problems faced by consultants and clients alike.

Problems Faced by Consultants

Unbillable Time:

Consultants often have unbilled time throughout the day. Due to the nature of the work, consultants might have unbilled time spent traveling or between clients. This is lost income. Over a week or month, all of these unbilled hours can add up.

Project Leads:

Getting leads for good projects can be difficult, and freelance marketplaces tend to be a pricing rice to the bottom. Consultants struggle to gain repeat customers, with word of mouth referrals, inbound marketing through blogs/social media, and networking events being the primary sources of leads.

Project Size:

Consultants focus on longer-term projects instead of short-term projects due to the two problems listed above. However, long-term projects are hard to find.

WhenHub sees all of these as supply-side problems. However, the ecosystem also has demand-side problems faced by clients.

Problems Faced by Clients of Consultants


Clients often struggle to find the right consultant available at the right time. If you need to consult a subject matter expert (SME), then you may not want to wait weeks for that expert to become available.


The process of finding a trustworthy, knowledgeable consultant is difficult and time-consuming, and involves asking friends, family and business associates for a reference. Online searches can be unreliable, and it can be hard to judge someone based on the things you see online.


You might find a knowledgeable consultant. However, that consultant may not be interested in your short-term project. That means you may have to settle for someone who isn’t the ideal fit, but is willing to work on your project.

Ultimately, WhenHub believes it can solve all of these problems with its blockchain-based ecosystem.

WhenHub Features

Here’s how WhenHub plans to solve the above problems:

  • InterfaceHub: The InterfaceHub is the section on WhenHub.com and the mobile app where users can “interface” with other users who have posted available time slots.
  • Interface App: This is the mobile app that works as the primary means for users to add availability time slots and “interface” with other users during scheduled time slots.
  • WhenSense Sites: These sites consist of websites running WhenSense so users can interface with other users based on real-time availability.
  • Partners: Partners are companies that provide verification services for Interface users.

The entire transaction is performed over a smart contract. The WIN ecosystem is built on the Ethereum blockchain, and WHEN tokens are ERC20 standard tokens.

The WHEN Token Sale

The WhenHub token pre-sale is scheduled for October 26 to November 9, 2017, with a public scale taking place from November 10 to December 31, 2017.

Tokens can be used for all transactions on the platform.

350 million tokens (40% of the total supply of 875 million) will be available during the token sale. 26% will be distributed to network users (to incentivize user participation).
