#etl

Transmutify

A tool that turns messy customer spreadsheets, CSVs, and even photos of data into clean, schema-matched records, with a human review step before anything gets used.

Reble

Git-like branching for Apache Iceberg data warehouses, so you can test SQL transformations without copying data

Danubia

EU-hosted content extraction API that turns any webpage into clean markdown or plain text, built for developers feeding web content into RAG pipelines and AI applications.

Cassis Context Bootstrap

Open-source tool that reads your existing dbt project, database schema, dashboards, and query logs, and automatically builds a structured map of your data's meaning — so an AI analytics agent has real context instead of guessing what a column means.

Syncle

Open-source self-hosted tool for real-time data replication across multiple database engines (PostgreSQL, MySQL, MongoDB, Redis, SQLite, MariaDB). Eliminates need for Kafka or Debezium with lightweight synchronization via CDC, polling, or backfill.

dataset-cleaner-cli

Open-source Python CLI that turns technical documentation into clean Q&A training datasets for LLM fine-tuning, using a local model.

Syncs Stripe, HubSpot, Postgres, and 40+ other business tools into one encrypted data lake you can query directly from Claude or Codex, without waiting on engineers or building a BI stack.

Miller

A command-line tool that does to CSV, TSV and JSON what awk and sed do to plain text — filter, reshape and transform tabular data without spinning up a Python script.

Decode GA4

Decode GA4 automatically flattens Google Analytics 4's nested BigQuery export data into clean, ready-to-query tables, with usage-based pricing and no subscription.

Datatera.ai

Feed it a messy pile of PDFs, invoices or web pages and Datatera.ai turns them into clean, structured spreadsheet or CRM records — with an audit trail so a finance or legal team can trust where each number came from.

Quix

A streaming data platform, built by the people behind McLaren's Formula 1 data systems, that connects sensor data from R&D, testing, and production into one live feed instead of three disconnected systems.

Definite

A Python-native orchestration platform for running data pipelines, dbt workflows, and AI agents on either serverless or self-hosted infrastructure.

Data-syncing platform that moves data both ways between a company's warehouse and the everyday tools (Salesforce, Google Sheets, Stripe) that teams actually work in.

Kleene.ai

A data platform that pulls data from 200+ sources into a warehouse and lets you query it in plain English via an AI assistant.

Tonic.ai

Generates realistic fake versions of your production data — same shape and statistics, no real customer information — so developers can test against data that looks real without ever touching actual user records.

Artie

Fully-managed change-data-capture platform that streams database changes into data warehouses in real time, without building Kafka/Debezium pipelines yourself.

Estuary

Real-time data movement platform: streaming, log-based CDC and batch through 200+ managed connectors, sub-100ms latency.
