Agents are the New Developer

80% of Claude Code was written by AI. More than a quarter of all new code at Google was generated by AI one year ago. It’s safe to say that in the next 12 months, the majority of all new code will be written by AI.

Agents don’t behave like humans. They behave in new ways. Software development tools need to evolve. Agents need a new kind of database made for how they work.

But what would a database for agents look like?

At Tiger, we’ve obsessed over databases for the past 10 years. We’ve built high-performance systems for time-series data, scaled Postgres across millions of workloads, and served thousands of customers and hundreds of thousands of developers around the world.

So when agents arrived, we felt it immediately. In our bones. This new era of computing would need its own kind of data infrastructure. One that still delivered power without complexity, but built for a new type of user.

What Agents Actually Need

Agents work differently than humans. They need:

MCPs, not UIs – they call functions, not click buttons
Native search – find the right data instantly
Fast forks and teardown – spin up experiments without the overhead
Efficient pricing – pay for what you use
Built-in knowledge – best practices that come with the database

What We Built

1. An MCP Server That Actually Understands Postgres

We built an MCP server that doesn't just connect to the database—it knows how to use it well. We took 10+ years of Postgres experience and turned it into built-in prompts. Agents get tools for schema design, query optimization, and migrations, plus they can search Postgres docs on the fly.

> service on Tiger. Then using Postgres best practices, describe 
> the schema you would create.

2. Search Built Into the Database

pgvectorscale: We improved our vector search extension. Better indexing throughput, better recall, lower latency than pgvector.

pg_textsearch: Our newest extension. It implements BM25 for proper ranked keyword search, built for hybrid AI apps. Right now it uses an in-memory structure for speed—disk-based segments with compression are coming.

No need to bolt on external search. It's all in Postgres.

3. Instant Database Forks

We built a copy-on-write storage layer that makes databases instantly forkable. Full production data, isolated environment, seconds to create. No data duplication, no cost duplication. You only pay for what changes.

Great for testing, benchmarking, or running migrations in parallel without touching prod.

> Create a fork of my database, test 3 different indexes 
> for performance, delete the fork, and report findings.

4. New CLI and a Free Tier

Three commands to get started:

# Install the Tiger CLI and MCP
$ curl -fsSL https://cli.tigerdata.com | sh
$ tiger auth login
$ tiger mcp install

Then either tell your agent to create a free service, or run tiger create service yourself.

Fluid Storage

This all runs on Fluid Storage—our new distributed block store. It's built on local NVMe with a storage proxy that handles copy-on-write volumes.

What you get:

Instant forks and snapshots
Automatic scaling, no downtime
Over 100K IOPS and 1 GB/s per volume

It looks like a local disk to Postgres but scales like cloud storage. Every free service runs on it.

Built for agents. Designed for developers.

🐯 🚀 Timescale is now TigerData: Building the Modern PostgreSQL for the Analytical and Agentic Era

Ajay Kulkarni — Wed, 18 Jun 2025 16:09:24 +0000

TL;DR: Eight years ago, we launched Timescale to bring time-series to PostgreSQL. Our mission was simple: help developers building time-series applications.

Since then, we have built a thriving business: 2,000 customers, mid 8-digit ARR (>100% growth year over year), $180 million raised from top investors.

We serve companies who are building real-time analytical products and large-scale AI workloads like: Mistral, HuggingFace, Nvidia, Toyota, Tesla, NASA, JP Morgan Chase, Schneider Electric, Palo Alto Networks, and Caterpillar. These are companies building developer tools, industrial dashboards, crypto exchanges, AI-native games, financial RAG applications, and more.

We’ve quietly evolved from a time-series database into the modern PostgreSQL for today’s and tomorrow’s computing, built for performance, scale, and the agentic future. So we’re changing our name: from Timescale to TigerData. Not to change who we are, but to reflect who we’ve become. TigerData is bold, fast, and built to power the next era of software.

Developers Thought We Were Crazy

When we started 8 years ago, SQL databases were “old fashioned.” NoSQL was the future. Hadoop, MongoDB, Cassandra, InfluxDB – these were the new, exciting NoSQL databases. PostgreSQL was old and boring.

That’s when we launched Timescale: a time-series database on PostgreSQL. Developers thought we were crazy. PostgreSQL didn’t scale. PostgreSQL wasn’t fast. Time-series needed a NoSQL database. Or so they said.

“While I appreciate PostgreSQL every day, am I the only one who thinks this is a rather bad idea?” – top HackerNews comment on our launch (link)

But we believed in PostgreSQL. We knew that boring could be awesome, especially with databases. And frankly, we were selfish: PostgreSQL was the only database that we wanted to use.

*Today, PostgreSQL has won. *

There are no more “SQL vs. NoSQL” debates. MongoDB, Cassandra, InfluxDB, and other NoSQL databases are seen as technical dead ends. Snowflake and Databricks are acquiring PostgreSQL companies. No one talks about Hadoop. The Lakehouse has won.

*Today, agentic workloads are here. *

Agents need a fast database. We see this in our customer base: private equity firms and hedge funds using agents to help understand market movements (“How did the market respond to Apple WWDC 2025?”); industrial equipment manufacturers building chat interfaces on top of internal manuals to help field technicians; developer platforms storing agentic interactions into history tables for greater transparency and trust; and so on.

What Started as a Heretical Idea Is Now a Thriving Business

We have also changed. We met in September 1997, during our first week at MIT. We soon became friends, roommates, even marathon training partners (Boston 1998).

That friendship became the foundation for an entrepreneurial journey that has surpassed even our boldest imaginations.

What started as a heretical idea is now a thriving business:

2,000 customers
Mid 8-digit ARR, growing >100% y/y
200 people in 25 countries
$180 million raised from top investors
60%+ gross margins
Cloud usage is up 5x in the last 18 months, based on paid customers alone.

And that’s only the paid side of the story. Our open-source community is 10x-20x larger. (Based on telemetry, it’s 10x, but we estimate that at least half of all deployments have telemetry turned off.)

TimescaleDB is everywhere. It’s included in PostgreSQL offerings around the world: from Azure, Alibaba, and Huawei to Supabase, DigitalOcean, and Fly.io. You’ll also find it on Databricks Neon, Snowflake Crunchy Bridge, OVHCloud, Render, Vultr, Linode, Aiven, and more.

We Are TigerData

Today, we are more than a time-series database. We are powering developer tools, SaaS applications, AI-native games, financial RAG applications, and more. The majority of workloads on our Cloud product aren’t time-series. Companies are running entire applications on us. CTOs would say to us, “You keep talking about how you are the best time-series database, but I see you as the best PostgreSQL.”

So we are now “TigerData" We offer the fastest PostgreSQL. Speed without sacrifice.

Our cloud offering is “Tiger Cloud.” Our logo stays the same: the tiger, looking forward, focused and fast. Some things do not change. Our open source time-series PostgreSQL extension remains TimescaleDB. Our vector extension is still pgvectorscale.

Why “Tiger”? The tiger has been our mascot since 2017, symbolizing the speed, power, and precision we strive for in our database. Over time, it’s become a core part of our culture: from weekly “Tiger Time” All Hands and monthly “State of the Tiger” business reviews, to welcoming new teammates as “tiger cubs” to the “jungle.” As we reflected on our products, performance, and community, we realized: we aren’t just Timescale. We’re Tiger. Today, we’re making that official.

This is not a reinvention: it’s a reflection of how we already serve our customers today.

Polymarket uses TigerData to track their price history. During the last election Polymarket ramped up 4x when trade volumes were extra high, to power over $3.7 billion dollars worth of trades.

Linktree uses TigerData for their premium analytics product, saving $17K per month on 12.6 TB from compression savings. They also compressed their time to launch, going from 2 weeks to 2 days for shipping analytical features.

Titan America uses TigerData’s compression and continuous aggregates to reduce costs and increase visibility into their facilities for manufacturing cement, ready-mixed concrete, and related materials.

Lucid Motors uses TigerData for real-time telemetry and autonomous driving analytics.

The Financial Times runs time-sensitive analytics and semantic search.
