What People Say
"As a former CEO of a global asset manager, I know firsthand how much time and money is wasted when investment teams have to clean bad data or build in-house fixes that never scale. Poor data quality is one of the most persistent - and costly - headaches in our industry. sieve has solved this problem at the root.
By combining AI with rigorous human validation, they've created the clean data layer that our industry has needed for decades. Spotless data isn't a nice-to-have, it's a top priority, and sieve finally delivers it - freeing teams to focus on strategy and performance rather than cleaning data."
Aaron Meder
Former CEO, L&G – Asset Management, America
"Working with sieve has been incredibly easy. They turn things around quickly, the quality of the work is consistently high, and they've been very responsive whenever we need something. When building a complex, high surface area product (100s of providers and integrations), reliable human review is extremely valuable - it gives us confidence in the quality of what we're shipping. Would recommend!"
Kevan Dodhia
Co-founder and CTO of Alter (YC S25)
"I'm super impressed - it works much better than a lot of things I've tried, especially for something out of the box!!"
