Build a bespoke AI system
for your Fund

Engineering

Harness the latest agents

Securely harness Claude Code and other state of the art agents to do work for your firm.

Engineering
Workflows

Encode your firm's processes

The way your team builds a thesis, runs a screen, prepares for earnings – drilled into your AI.

Workflows
Research

Automated research

Daily coverage of every name on your watchlist. Your docs update with prints, guidance and filings the moment they cross.

Research
Security

Hedge-fund-grade infrastructure

Tenant isolation. No training on your data. Controls treated as a design constraint from day one — not a compliance afterthought.

Security
Data

Organize your data

Agents that maintain your file structure, enforce your ontology, and keep the archive queryable — without anyone playing librarian.

Data
Enablement

Training & governance

Seminars, playbooks, and direct support — so AI gets used well across the firm, not just by the people who already love it.

Enablement

Integrate everything

Connected once, governed properly, kept in sync — so the system thinks across your stack the way your team already does.

The exposure.

Don't see something? If your firm runs on it, we'll connect to it. Custom integrations are part of the partnership, not a line item.

The work, in their words

Mercator Partners has been running on WithAI since day one. Their CIO and Head of Primary Research on what changed.

We used to spend 80% of our time gathering information and 20% acting on it. WithAI has flipped those percentages.
Martin Fransson, PhD
Martin Fransson, PhDHead of Primary Research
WithAI 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.

Three things, plainly stated.

I

A team working with you. Not another SaaS subscription.

You get engineers and analysts inside your operation — learning how your firm thinks, and staying close enough to fix what doesn't work.

II

The best models, let loose on your existing work.

Frontier models, conditioned on your memos, models, and taxonomies. The product reshapes itself around you — not the other way around.

III

Secure by posture. Not by checkbox.

Tenant isolation, no training on your data. Treated as a design constraint from day one — not a compliance afterthought.

Two founders. Both close to the work

WithAI is built by the people who'll sit across the table from you.
