AI for asset managers, built with you
Security, infrastructure, and white-glove service for harnessing the latest agents
Introducing Multiplier
We learned what it takes to make AI work for investors and turned that into a platform.
Frontier agents
You get the world's best AI, in the best harnesses, straight from the source.

Your firm's processes
Multiplier learns where you seek edge, how you model a business, and what you care about.

Automated research
Agents can research every stock on Earth, every day, watching for setups or updating projections.

Data security
Everything lives on your cloud — neither we nor Anthropic can see your data.

Ontology and search
Multiplier enforces your folder structure so agents and humans can always find what they need.

Personalized support
WithAI's founders won't rest until you and all your analysts love Multiplier.

One command center
Channel checks, expert calls, sellside research, company financials, portfolio risk measures and trade history – all at your fingertips. Where connectors are flaky or nonexistent, we build our own.

Hear from a client
It's tough to get public testimony from a hedge fund, but Mercator Partners likes WithAI just that much.
“We used to spend 80% of our time gathering information and 20% acting on it. WithAI has flipped those percentages.”
“Multiplier eliminates the need to search every 'haystack' as the 'needles' are floated to the top and organized by importance, impact, and relevance for the portfolio.”
The founders
As undergraduates, Ben & Ian co-founded the Tiger Sustainable Investment Group.
