The 10 Hottest Cloud Computing Startups Of 2021 (So Far)

The cloud computing startups, all of which recently landed venture capital funding, range from an MLOps company that emerged from stealth mode in April to an IoT cloud platform provider for hardware developers to a cloud cost management software company.

End-user spending on cloud computing is continuing to see healthy, double-digit growth rates, and it’s an opportune time for innovative cloud startups to help organizations moving beyond coronavirus pandemic-accelerated migrations to more fully mine the technology industry’s hottest sector.

Gartner expects global public cloud end-user spending to increase 23.1 percent this year to $332.3 billion. The growth will be driven in part by emerging technologies — including containerization, virtualization and edge computing — becoming more mainstream, according to the research and advisory firm. The pandemic has been a “multiplier” for chief information officers’ interest in the cloud, says Gartner research vice president Sid Nag, who views cloud as the ”glue” between other technologies such as artificial intelligence (AI) and the internet of things (IoT) that CIOs want to use.

Established cloud providers and their investment arms are stepping up their games to support startups with new programs to help the early-stage companies and expose them to their own enterprise customers. Amazon Web Services launched the AWS Partner Network Global Startup Program in 2019 to help startups with compelling enterprise products better-leverage its benefits, including its go-to-market efforts. And Salesforce Ventures, the investment arm of customer relationship management leader Salesforce, last October announced a new $100 million fund to accelerate the growth of cloud companies.

Here’s CRN’s list of 10 cloud computing startups to watch so far in 2021. They range from an MLOps company that emerged from stealth mode in April to an IoT cloud platform provider for hardware developers to a cloud cost management software company. All of them were boosted by recent venture capital funding rounds.

Filebase offers Amazon Simple Storage Service (Amazon S3)-compatible and cloud-managed object storage powered by blockchain. Its platform seamlessly connects applications to several decentralized storage networks as a drop-in, encrypted and geo-redundant replacement for S3 and traditional cloud storage at a fraction of the cost, the Boston company says.

The Filebase platform features a browser-based dashboard and an S3-compatible API to deploy, access and manage data across the Sia, Storj and Skynet storage networks. Filebase takes advantage of unused storage capacity and rents storage from the networks, managing all storage contracts on behalf of the user.

Its platform abstracts all interactions with the underlying networks and has turn-key configurations to help developers move or replicate data. While decentralized storage networks can suffer from higher latency compared to centralized alternatives, Filebase’s proprietary, edge-caching technology increases throughput and lowers response times for both ingress and egress, according to the company.

Customers are using Filebase primarily for geo-redundant disaster recovery, cost-cutting and Web3 development. It plans to add support for the Filecoin and Arweave storage networks by year’s end.

In April, the seed-stage startup announced a $2 million funding round led by Austin’s Multicoin Capital with participation from Vancouver, Canada-based Version One Ventures and angel investors including Ryan Selkis, founder and CEO of New York’s Messari. Filebase said it planned to use the funds to onboard customers and hire new engineering, marketing and sales employees.


CEO: Jonathan Beri
