Meltano strikes past ELT to turn out to be an ‘open-source dataops OS’

Meltano, the info integration firm spun out of GitLab final 12 months, as we speak unveiled model 2.0 of its platform. And to energy its transition into what it calls an “open-source dataops OS,” the corporate additionally introduced a recent $8.2 million in seed funding.

Debuting internally at GitLab again in 2018, Meltano emerged as what is named an “extract, load, transform” (ELT) platform that helps corporations “extract” uncooked knowledge from disparate silos (e.g., a number of SaaS apps); “load” this knowledge in a warehouse or file-storage system; and “transform” the info right into a standardized format that’s simpler to research.

Meltano occupies a broader knowledge integration house that features numerous incumbents, from proprietary gamers comparable to Fivetran to open-source newbies like Airbyte. Meltano, for its half, resides squarely within the open-source realm, and guarantees knowledge engineers flexibility and extensibility — it may be hosted wherever they please, and accessed through their very own orchestration instruments or by Meltano’s personal net interface.


With Meltano 2.0, which is formally accessible as we speak, Meltano says that it’s ending the period of “duct-taped data platforms,” providing a complete product that groups can use to create and handle their “ideal” knowledge stack.

What this implies is that Meltano is transferring past ELT, packaging instruments from throughout the complete knowledge stack — from integration by to enterprise intelligence (BI) and evaluation.

“This allows not just a team’s data pipelines to be managed like a software project, but their entire end-to-end data platform from EL (extract & load) to BI,” Meltano CEO Douwe Maan instructed VentureBeat.

While the Meltano platform is an open-source product in its personal proper — launched beneath a permissive MIT license — it truly adopts a modular method, leaning on a bunch of third-party open-source instruments comparable to dbt, a command-line software for knowledge transformation; Apache Airflow for orchestration; and Singer, which is an “open-source standard” for writing knowledge integration scripts. And earlier this 12 months, Meltano launched help for knowledge high quality open-standard Great Expectations.

The firm was all the time planning to help Apache Superset for knowledge visualization, and with model 2.0 that plan has now come to fruition, with customers now capable of set up, configure, combine, take a look at and deploy Superset straight by Meltano. Moreover, Meltano additionally helps different knowledge visualization and BI instruments comparable to Lightdash and

“This makes Meltano the MVP [minimal viable product] of our dataops OS vision, and the first major step in addressing the complexity and fragility of today’s modern data stack, by bringing in some much-needed infrastructure to hold it all together, and software development best practices to allow rapid iteration with confidence,” Maan continued.

Elsewhere, Meltano has now widened the scope of its plugin hub, permitting customers to seek out not simply supported EL connectors, however the entire open-source instruments to energy their knowledge stack.

“We intend for this to become a library of all open-source data tools in the ecosystem, with Meltano the easiest way to install them and use them together,” Maan stated.

Finally, Meltano has eliminated a bunch of previous options, comparable to its legacy BI / visualization performance that it designed internally, which now makes approach for the aforementioned open-source third-party incarnations.

From GitLab to GitHub

The launch of model 2.0 additionally follows shortly after Meltano migrated from its authentic residence on GitLab over to GitHub, which it stated was to help its continued development within the open-source fraternity. Put merely, GitHub has a wider attain when it comes to community-driven knowledge tooling initiatives.

“GitLab is a great tool for collaboration inside companies, especially all-remote ones, and it’s obviously close to our hearts since we were born there,” Maan stated. “But as our growth accelerates and the community diversifies, the move to GitHub just makes sense.”

At its official spinout from GitLab final 12 months, Meltano had revealed a $4.2 million seed spherical of funding spherical led by Alphabet’s VC arm GV, together with a slew of angel investments from the likes of WordPress founder Matt Mullenweg and early Google backer Ram Shriram. Meltano has now prolonged this seed spherical to $12.4 million in complete, with Venrock spearheading the extra elevate and GV, Uncorrelated Ventures, and Data Tech Fund all taking part.
