Albert Chiu

Co-founder, Alchemunity

"Alchemunity is building a transparent and trustless freelancing community, that's our business. Blockchain is the magic ingredient. With MultiBaas we're able to focus on developing our platform, with the right level of decentralization for each task. It helps keep us and our users focused and engaged with our platform, while taking advantage of all that decentralization has to offer."

Matsumoto Oki

"Smart contracts can be used as programmable financial instruments, to design smart money. It is going to revolutionize the finance industry, but smart contracts and blockchain are hard to build on and use. I believe MultiBaas will make blockchain technology workable for everyone from established institutions to upstart hedge funds."

Hogi Hyun

Founder/Director, Abacus Capital

"The team at Curvegrid did a phenomenal job working on our on tokenization project. From inception, with defining the project brief and the architecture of the smart contract eco-system, to the step-by-step execution of a multi-stage development, and handholding on the practical implementation side, Curvegrid were incredibly able and supportive. Curvegrid would be our first choice in any blockchain project that we undertake in the future."

Recruit Strategic Partners

"We consider engineering effort and complexity to be a major issue for blockchain applications. We're excited about MultiBaas because it drastically reduces time-to-market for decentralized applications. Enterprises can use existing software engineering resources to get a product out the door faster."

FAQ

What does the free plan include?

The free plan allows you one MultiBaas deployment for testing and evaluation. Curvegrid may reclaim any free deployment that has not been logged into for 14 days. Please be sure to login regularly, and backup your data if need be.

How do I sign up for a free or paid plan?

Click Get Started at the top of the page, or on one of the buttons under a plan in our pricing table, to be taken to the Curvegrid Console. Create an account, and select the desired free or paid plan. For paid plans, enter your credit card and billing information. You will then be able to create one or more MultiBaas Deployments according your plan level.

Can I sign up for multiple plans?

Your Account with Curvegrid is associated with one or more Organizations within the Curvegrid Console. When you create your account, we also create a personal organization. Organizations subscribe to plans, and you may create multiple organizations from one account, each with its own free or paid plan. You can invite other users to join your organizations and grant them appropriate billing or administrative privileges.

What payment options are available?

Payment may be made via credit card on our website.

When will I be billed for my subscription?

Your credit card will be charged upon signing up for one of our paid plans, for the pro-rated amount through the end of the current billing period. For monthly billing, a billing period is defined as the first day of the month through the last day of the month. For subsequent billing periods, your credit card will be charged at the beginning of the billing period for the full amount due for that billing period.

Can I cancel my subscription?

You may cancel your subscription at any time by contacting support@curvegrid.com. No refunds will be given for cancelling part way through a billing period, however, you will have full use of the MultiBaas services at the level of your subscription through the end of the billing period.

Can I upgrade my subscription?

Yes, please contact support@curvegrid.com to upgrade your subscription. Upgraded subscriptions will be charged the pro-rated difference between their current subscription and their new subscription through the end of the current billing period, and for the full amount of the new subscription at the beginning of subsequent billing periods.

Can I downgrade my subscription?

Yes, please contact support@curvegrid.com to downgrade your subscription. No refunds will be given for downgrading a subscription part way through a billing period, however, you will have full use of the MultiBaas services at the level of your subscription through the end of the billing period. You will be charged the full amount of the new subscription at the beginning of subsequent billing periods. Prior to downgrading your subscription, you must bring your MultiBaas organization and its deployments in line with the plan features of the new, downgraded plan. This could require you to remove deployments and delete data. Curvegrid is not responsible for data loss due to user action or subscription downgrade requirements. Please backup your data if need be.

Can I delete my data, deployments, organization, and account?

Yes. Data within a MultiBaas deployment can be deleted within that deployment by any user with sufficient access privileges. Deployments can be deleted from the Curvegrid Console. Curvegrid is not responsible for data within a deployment. Please backup your data if need be. To delete your organization or account, please contact support@curvegrid.com. Curvegrid does not guarantee the ability to restore any deleted data, please backup your data if need be.
