START: Ian M.J. McInnis, CEO & Co-Founder, WithAI “Custom command centers for hedge funds”

The biggest hedge funds have entire teams building AI. Most asset managers are on their own.

But closing that gap isn't about buying more AI. It's about a problem most people get wrong.

You can test code by running it.
You can't test an investment by buying it.

Software engineering and investing aren't the same problem

In software, we've moved from autocomplete to agents to long-running agent swarms - each step climbing another level of abstraction

In investing, human judgment still has to exist at the object level

So the challenge was never deploying agents

The challenge is giving them the context to be useful

Every source of knowledge

Internal and external

Structured and unstructured

Connected to the people making decisions.

That's what Ian M.J. McInnis and his co-founder Ben Finch built at WithAI (YC P26)

Not another AI tool

A customized environment where agents can work the way investors actually do.

Ian knows the problem firsthand. Before co-founding WithAI, he worked at the center of AI and investing at Bridgewater, studying how AI would reshape markets and knowledge work.

His conclusion after trying the alternative:

"The DIY approach ends in pain"

The future isn't simply managing swarms of agents

It's knowing what to delegate

What to automate

And where human judgment remains essential

That's why WithAI focuses on amplifying investors rather than replacing them

Research faster

Monitor more companies

Surface information that would otherwise be missed

"AI for asset managers, built with you": Security, infrastructure, and white-glove service for harnessing the latest agents
