Built inside 776
The investor operating system a venture firm actually runs on.
Sourcing, diligence, decisions, introductions, portfolio operations, and fund accounting, with AI running through the middle of it rather than bolted onto the side. In production since 2020. Every partner at 776 uses it daily, and so do the founders they back.
Access is by invitation.
The live record, inside the assistant.
Cerebro speaks Model Context Protocol, so the assistant someone already has open can query the firm's live record, and act on it, with exactly that person's permissions.
Most AI + your data
Most AI plus your data is a chatbot with a stale copy of your documents. It knows what was true when the copy was made and can do nothing about it.
Cerebro over MCP
Cerebro queries the live record when you ask. It can write back through the same rules the app enforces.
- Tool calls a month, and rising.
- 9,000+
- Distinct capabilities the assistant can call.
- 50+
- Calls that write back, not just read.
- 1 in 5
- Calls completing without error.
- 99.9%
Ask across the firm
Ask one question spanning notes, files, conversations, calendar, and relationships. Cerebro pulls the answer from the live record instead of making you search each system yourself.
Give me background on this company.
Meeting prep on request
Meeting prep is assembled when you need it. The relevant context comes together from the firm's live record instead of being collected by hand.
Brief me on the two o'clock.
Find the real relationship
Cerebro finds who at the firm actually has the relationship. It derives that answer from what people write, not from who is copied on an email.
Who here has the strongest line to this company?
Write it back
The result can become a note, task, or field in the record. It is written under that person and logged through the same permissions as the app.
Capture that as a note on the company and flag the follow-up.
Ask across the portfolio
Portfolio-wide questions run against the same figures the fund reports on. The answer comes from the record that already supports the firm's reporting.

The note exists before the meeting does
Automatic notes
LiveCerebro reads the calendar ahead of time and creates the meeting and the note on its own. Every attendee is matched to a person already in the system and linked, with the company they work at. It goes live shortly before the meeting starts.
Nobody opens a blank page. The record already knows who is in the room.
- 001
A warm introduction from whoever actually has the relationship
Introductions
LiveFind any person in Cerebro and ask for an introduction from their profile. The request goes out from whoever at the firm genuinely knows them, which is often Alexis. Both sides opt in before anyone is put in a room.
Consent is part of the mechanism, not a courtesy. Nobody is volunteered.
- 002
Founders borrow the loudest account in the room
Amplify
LiveDraft, review, schedule and publish to X, LinkedIn and Instagram, including through Alexis’s own accounts. His reach is orders of magnitude larger than a typical founder account. Founders warm a vertical up before their outreach lands there.
Distribution is a service the firm runs, not advice it gives.
- 003
One note, written while the meeting happens
Collaborative notes
LiveReal-time multiplayer editing with live cursors and presence, the way a shared document works. Two people on the same call write one note instead of two. This is how the firm runs its own internal meetings.
The record is agreed while everyone is still in the room.
- 004
One box across everything the firm knows
Network search
LiveCompanies, people, notes, files, conversations and meetings answer together. Exact names and vague descriptions both work, because keyword and meaning-based search run at once and the rankings are combined. Results only ever contain what you are allowed to see.
You can find a meeting you can describe but cannot name.
- 005
The room tells you it is about to start
Meeting reminders
LiveA few minutes before a call, a card slides in wherever you are in Cerebro: who is coming, how long you have, and one click into the note that already exists for it. Only for meetings with someone else on them, and it goes away the moment you dismiss it — in every tab at once.
The prompt arrives with the record attached, not just the calendar entry.
- 006
Every asset searchable, including inside the video
Media
LiveThe firm’s photo and video library, searchable by what is in it. Transcripts are indexed by timestamp, so you can jump to the moment someone said the thing. It is also the engine behind the private dinner series at 776table.com.
Search does not stop at the filename.
- 007
Founders put the partner in the close
Muse
LiveA founder gives the occasion and what would land; a 776 partner records an unscripted thirty-second video on their phone. Muse returns a shareable page to send to a candidate, new hire or customer.
The partner’s voice is a standing capability, not a favor.
Every app screen is a synthetic demo workspace — the companies, people and figures are invented. A handful are real and public on purpose, like the 776 Table dinner and the Muse video Alexis recorded. Click any screen to see it in full.
000DashboardWhere the day starts: what is overdue, which meetings need notes, and the week beside it. 001PortfolioThe whole book in one table, filterable by stage, sector, health, fund and owner. 002Company timelineEvery meeting, note and update against one company, in order. 003Meeting noteNotes are written where the meeting lives — with the rating, the tasks and the comments attached. 004Note typesForty-odd meeting types, each with its own structure, so a pitch is recorded like a pitch. 005IntroductionsEach request in the open, at the stage it has reached: asked, consent sought, sent, met. 006AmplifyFounders draft the post; it waits for approval before anything is published on their behalf. 007SearchOne box across companies, people, notes, groups and campaigns. 008MediaOne evening from the 776 Table dinner series — indexed by what is in each frame, not what the file is called. 009Muse inboxThe requests founders make — recorded on a phone, sent back as the shareable page beside this one.
For founders
It is not just an internal tool.
Every 776 portfolio founder gets an account, and they do not use it to read a dashboard. They use it to ask for things. Over the last 90 days, more than forty portfolio companies had a live channel in Cerebro, and the requests coming through them were the real ones: a warm introduction to a specific buyer, a reference call with a lead investor mid-round, help closing a candidate who wanted to talk to an investor before signing, a press contact on a deadline.
The reason that works is the same relationship graph the firm uses internally. When a founder asks for an introduction, the request routes to whoever at 776 actually has the relationship, rather than to whoever happens to read the message first. The founder does not have to know who to ask, which is usually the hard part.
- 008Campaigns
- Batch outreach at volume, tracked and personalized, with engagement measured per recipient. The founder brings the strategy and 776 executes the wave.
- 009Executive briefings
- A daily brief per person, aware of travel, priorities, and who they are about to see.
- 010Portfolio metrics
- Metrics written into the record by the AI layer are rolled up daily for a human to review afterwards, rather than gating every write in advance. Review the exceptions, not the stream.
- 011Signal strength
- Relationships are scored by who the firm actually writes about, read from mentions across meeting notes. It measures attention rather than activity.
- 012Deal pipeline
- A board built for how a fund decides. Founder journeys, partner ratings over time, and a field-level audit trail, so "why did we pass" has an answer six months later.
- 013Portfolio operations
- Company cards, quarterly reviews, cash tracking and fund accounting, reconciled against the book of record.
- 014Founder Library
- The welcome pack every portfolio company gets, living inside the product: templates, playbooks, and who at 776 to go to for what.
- 015Agents and tools
- One registry serving both the Slack agent and MCP, so a capability added once works in both.
- 016Fund management
- 017Tasks
- 018Email intelligence
- 019Native mobile app
