Draft:PlanetScale

PlanetScale is a database-as-a-service company founded in 2018, with headquarters in San Francisco, California. Its fully-managed relational database platform offers hosted PostgreSQL and MySQL (Vitess), supporting companies with large-scale databases such as MyFitnessPal, Intercom, Cursor, and Block. PlanetScale's products provide horizontal scalability, non-blocking schema changes, and high availability for large-scale production workloads. Beyond serving enterprise-scale organizations, the platform accommodates single developers and lightweight projects through various accessible, entry-level pricing tiers.

History

Founding and background

Jiten Vaidya and Sugu Sougoumarane first met at the Indian Institute of Technology Bombay. In 1993, they worked together at Informix, a database company. Sougoumarane went on to work as an early engineer at X.com, while Vaidya went to Google. They crossed paths again at YouTube.

In 2010, while working at YouTube, they addressed the problem of scalability of the website's MySQL database infrastructure by creating Vitess, a relational data storage system. Vitess is an open source project that provides the technology to run MySQL databases in the cloud.

YouTube eventually migrated off of Vitess, and the project was subsequently donated to the Cloud Native Computing Foundation (CNCF).

In the years that followed, tech companies reached out to ask for support building the operational infrastructure that would allow them to use Vitess with their databases. The result was PlanetScale, which launched in 2018 to bring a managed Vitess product to the public.

Early growth (2019–2020)

In May 2019, just one year after raising a $3 million seed round, PlanetScale announced a $22 million Series A funding round led by Andreessen Horowitz, with participation from existing investor SignalFire. Andreessen general partner Peter Levine joined the company's board as part of the round.

Platform launch and growth (2021)

On June 23, 2021, the company announced a $30 million Series B round led by Insight Partners, with participation from Andreessen Horowitz, a16z, and SignalFire.

A change in leadership came in July 2021. Sam Lambert, formerly the Vice President of Engineering at GitHub, had spent the last nine months as PlanetScale's Chief Product Officer before transitioning into the role of CEO, succeeding Vaidya, who moved into a chief strategy role. Around the same time, co-founder Sougoumarane embarked on a 4+ year sabbatical and did not return to the company.

On November 16, 2021, PlanetScale announced the general availability of its hosted enterprise platform alongside a $50 million Series C funding round led by Kleiner Perkins. Existing investors Andreessen Horowitz, SignalFire, and Insight Partners participated, as did notable angel investors including GitHub co-founder Tom Preston-Werner, Lattice CEO Jack Altman, and Instacart co-founder Max Mullen. The round brought total funding raised to $105 million.

Early enterprise customers at general availability included GitHub, Slack, MyFitnessPal, and Square.

Product expansion (2022–2023)

Through its various iterations, one of PlanetScale's stated priorities has been developer experience. The engineering team focused on database infrastructure challenges.

In March 2022, PlanetScale announced an “undo” button, allowing users to reverse migrations up to 30 minutes after the migration, reverting the schema back to its original state.

In May 2022, PlanetScale launched Insights, an observability tool for its database, eliminating the need for users to install a third-party APM to achieve better visibility. Insights gives full visibility into all operations and queries, making it easier for users to identify possible performance issues or misconfigurations faster, along with showing users exactly what it costs to run queries, making it clear what to optimize, in real time.

In August 2022, PlanetScale released a driver that adds a new API for the database, enabling queries over JavaScript to allow integration with edge deployment platforms.

In November 2022, PlanetScale introduced PlanetScale Boost, a product designed to accelerate query performance with an integrated form of data caching. This is different from an average data cache because it allows for query acceleration without additional application logic or infrastructure. Management and configuration are closely aligned with the database. In addition, the data caching is deployed next to the primary deployment. In testing, Boost reduced the time it took queries to generate a response from 500 milliseconds to just 5. This feature was later deprecated.

Inc. named PlanetScale one of the best places to work in 2022. It was also named in InfoWorld's 2022 Technology of the Year Awards, and was included in the CRN Big Data 100 list. In 2023, PlanetScale was recognized as a Fortune Best Small Workplace.

In October 2023, the company announced it was forking MySQL to add vector support.

In November 2023, PlanetScale was ranked number 188 on the Deloitte Technology Fast 500, an annual ranking of the fastest-growing technology companies in North America.

Restructuring (2024)

In March 2024, PlanetScale announced layoffs primarily affecting its sales and marketing teams and said it would retire its free "Hobby" tier as part of a push toward profitability. According to The Register, the company said existing Hobby-tier databases would be sunset on April 8, 2024, and that the move reflected a decision to focus on larger customers with large-scale or business-critical database needs.

In March 2025, the PlanetScale board asked Lambert to accept the title of Founder, acknowledging how he had fundamentally pivoted the company since 2020.

Recent product expansion

Metal (March 2025)

In March 2025, PlanetScale launched Metal, a new class of database instances that use locally attached NVMe SSDs rather than network-attached cloud volumes. Customer writeups published around the launch described the product as a response to storage I/O bottlenecks in large MySQL workloads and as a way to improve latency consistency and reduce infrastructure cost.

Block's Cash App engineering blog said its team had worked with PlanetScale for several months to migrate workloads to Metal after earlier cloud volumes showed degradation and IOPS-related write issues. Cash App wrote that, after the move, p99 latency on a main workload fell by 50% and performance remained stable during traffic spikes.

Intercom said it adopted PlanetScale Metal during its database migration away from Aurora and reported improved tail latency, no availability incidents on migrated databases, and a cost reduction of more than 60% compared with its earlier EBS io2-based setup.

Depot also published a case study on the launch date, saying that after moving to Metal, its query latency improved significantly and that the change let the company remove retention limits on build analytics data.

PlanetScale Postgres (2025)

On July 1, 2025, PlanetScale announced the private preview of PlanetScale Postgres, marking an expansion beyond the company's earlier focus on MySQL and Vitess-based database hosting. PlanetScale said the new managed service used PostgreSQL 17 and included high availability, automatic failover, connection pooling, and online imports from PostgreSQL 13 and later. The service became generally available on September 22, 2025.

Independent coverage described the launch as a notable shift for the company. The Register wrote that PlanetScale had previously been known for its MySQL-based platform built on Vitess before launching its PostgreSQL offering, while InfoQ said the release extended PlanetScale's platform to PostgreSQL users amid broader industry growth in PostgreSQL adoption.

Early customer adoption was highlighted during the rollout. In the private preview announcement, PlanetScale identified Convex as an early production user, and Convex separately wrote in July 2025 that it was moving from AWS Aurora to PlanetScale Postgres.

As part of that expansion, PlanetScale also announced Neki in August 2025, describing it as a PostgreSQL sharding system developed by the team behind Vitess for large-scale PostgreSQL workloads.

Then, in November 2025, PlanetScale introduced a paid single-node PostgreSQL option starting at $5 per month.

Database Traffic Control™ (2026)

In March 2026, PlanetScale introduced Database Traffic Control for PlanetScale Postgres. The feature allows users to define traffic budgets for subsets of query traffic based on query patterns, application names, database users, or SQL comment tags, with limits on CPU share, burst capacity, concurrency, and per-query execution time. PlanetScale said the feature could run in either warning or enforcement mode, and later added command-line management through the pscale traffic-control CLI command.
