BrainSite for investors

You posted the thesis. Now every founder in the space has a deck for you.

BrainSite gives investors a public AI agent for investment thesis, process, and pitch questions. It answers from your approved criteria and stage, then qualifies and routes founder outreach instead of leaving it stacked in your DMs.

A visitor asks

read your thesis on vertical AI, are you writing checks in this space right now?

BrainSite

I can share my current stage and check size for this sector. If it's a fit, I'll get you routed to submit a pitch.

What gets lost

Why does one thesis post turn into a stack of off-thesis pitches?

Writing up a thesis or breaking down a deal in public is how investors build a reputation and see more of the deal flow that actually fits. But every post that lands pulls in founders pitching regardless of stage or sector, because a founder raising has to reach out to everyone who might be a fit. Sorting a pre-seed SaaS pitch from something three stages or two sectors off, by hand, in your DMs, eats the time you'd rather spend with the deals actually in your lane.

The cost isn't just time. A founder who's genuinely a fit doesn't want to wait behind ten off-thesis pitches. If they don't get a clear answer on process and interest quickly, they take the round to the next investor whose DMs moved faster.

What changes

How does BrainSite separate a real pitch from an off-thesis DM?

BrainSite turns your X profile and public thesis into an AI agent that answers what every founder DM asks: stage, check size, sector focus, how you like to be pitched. It's built from theses and posts you already have, so you're not maintaining a separate one-pager just to answer the same questions.

A founder coming off your thesis post gets a real answer on fit immediately, and either gets routed to submit a pitch or book a call, or gets a clear, fast no instead of silence, without you triaging DMs between the deals you're actually working.

Choose the right approach

Should an investor use BrainSite, Intercom, a booking link, or hire an associate?

You don't need a customer service team or a new hire to get this. BrainSite sits in front of the stack you already have, no setup, no CS headcount, and no learning curve for a tool built for teams you don't have.

Option	Primary role	First visitor step	Best fit
BrainSite	Public agent for thesis questions and pitch intake	Answers from approved criteria and stage, then qualifies and routes	An investor who wants to stop triaging DMs by hand
Intercom	Customer service and messaging platform	Routes visitors into an established support or sales workflow	A team that already runs customer operations in Intercom
A booking link alone	Calendar scheduling only	Founder books a slot with no qualification first	Someone who doesn't mind calls with off-thesis founders
Hire an associate	Human deal-flow triage	A person reviews and qualifies inbound pitches	A fund with enough volume to justify dedicated headcount

From question to next step

What can a BrainSite do with the first visitor conversation?

Thesis questions answered instantly

Stage, check size, and sector fit get answered the moment someone asks.

Real fit signal, not a recap

Your approved criteria are already there to show, instead of you re-explaining your focus in every new DM.

Qualified pitches, fast no's

Founders who fit get routed to submit or book. Off-thesis DMs get a clear no instead of going unanswered.

The difference

How is BrainSite different from a static site or link page?

Visitor need	Static site or link page	BrainSite
DM after a thesis post goes wide	Buried under off-thesis pitches	Answers stage, check size, and fit immediately
Founder asks about your focus	You re-explain the thesis again	Shows approved criteria on the spot
Founder is actually a fit	Waits behind unrelated DMs	Gets routed straight to a pitch submission or call

FAQ

What should you know before creating a BrainSite?

Can it show my real portfolio and thesis?

Yes. You approve what it can reference, and it shows your actual stated focus and public portfolio instead of describing your thesis in the abstract. BrainSite doesn't generate investment recommendations on its own.

Can it filter pitches by stage and sector?

Yes, once you've added your criteria. It answers from what you've approved and routes or declines accordingly.

Does this replace me reviewing deals?

No. It handles the repeatable fit questions, so the pitches that actually deserve your attention reach you faster instead of waiting behind off-thesis DMs.

What if I don't have a formal process yet?

BrainSite works from whatever you have now, even just an X profile and a posted thesis. You don't need a formal pitch process to give founders somewhere real to ask questions.

How much setup does this take?

BrainSite learns from your X profile, threads, and any criteria you add. There's no separate deck or process doc to build first.
