“dlt has enabled me to completely rewrite all of our core SaaS service pipelines in 2 weeks and have data pipelines in production with full confidence. We also achieved data democracy for our data platform. Our product, business, and operation teams can independently satisfy a majority of their data needs through no-code self-service. The teams built multi-touch attribution for how Harness acquires customers, and models for how Harness customers utilize licenses. If the teams want to build anything else to push the company forward, they don't need to wait for permission or data access to do it.”

“I just wanted to reiterate how damned cool dlthub and the agentic workflows continue to be. We have a mountain of Klaviyo data, and API rate limits made extraction slow and prone to failure. The agent devised a tiered chunking strategy: 7 days, dropping to 1 day, then 1 hour on timeout, and it's gotten through some highly problematic data patterns without missing a beat. Super impressive, you guys are amazing!”
