Leni is the most accurate and verifiable AI for serious investment work. Built on 21,000+ decision traces and processing 100M+ rows daily, it delivers finance-grade outputs with full auditability through source links, timestamps, and grounded comps. Leni outperforms GPT, Claude, and Manus on independent benchmarks for accuracy, modeling, and valuation while giving teams the trust they need when millions are on the line. Leni is part of Google Startups and a serious machine for investors.
Three years ago, we started with a simple observation:
The smartest people in investing were spending an absurd amount of time moving data between systems, fixing spreadsheets, validating reports, and checking the outputs of tools that were supposed to save them time.
Everyone was talking about AI.
But when real money was involved, most professionals still didn't trust it.
And honestly, they were right.
In high-stakes work, "mostly correct" isn't good enough.
A wrong number, a missed assumption, or a hallucinated fact can cost millions.
So instead of building another chatbot, we spent years working alongside sophisticated investors, operators, lenders, and asset managers to understand what trustworthy AI actually looks like.
Since then, we've supported more than $80B in assets, processed over 100 million rows of investment data every day, built proprietary verification systems, and tested relentlessly against real-world workflows.
The result is Leni.
THE most reliable and accurate AI infrastructure platform for investors and back office work that can analyze hundreds of files simultaneously, reason through complex tasks, validate its outputs, and deliver finished work instead of just generating responses.
In independent testing, Leni now ranks among the top AI systems for spreadsheet analysis, reasoning, and resistance to hallucinations. That work also led to our selection as one of the few companies invited to Google's Gemini Forum, where we've had the opportunity to collaborate with the DeepMind team.
But what excites me most isn't a benchmark result.
It's seeing professionals finally trust AI with the work that actually matters.
Huge thank you to our team, customers, advisors, investors, and everyone who helped us get here.
We’re excited to finally put Leni and its API portal into the hands of the broader Product Hunt community and see what you build with it.

Who hunted Leni?
Leni was hunted by KP. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
