Your Chief of Staff · For Partners & GPs

Your network is the fund.
Cossi keeps it warm.

Two hundred LPs, portfolio founders, co-investors, and prospects. You can't hold all of it — and you can't put it in a CRM someone else controls. Cossi runs a loop on your device: notices who's drifting, prepares you for every call, drafts the reconnect, and hands you tomorrow already anticipated. Recoverable only by you.

The stakes
Your edge is your network.
Your network shouldn't live in someone else's cloud.

Deal flow, LP relationships, portfolio context, co-investor gossip — these are the most valuable and sensitive assets in your fund. Today, most of it lives in a CRM, a notes app, or a productivity tool storing your data on servers you don't control, can't audit, and can't protect from breach or subpoena.

Cossi runs the loop on your device. Brief, prepare, act, remember, anticipate — encrypted with keys only you hold. No CRM vendor. No cloud. No data policy you have to hope they honour.

The loop, for GPs

Notice. Prepare. Reconnect.

A 200+ person network. Deal context at the moment you need it. LP communications that never leave your device. The loop, tuned for partners.

👥
Relationship Health
Health scores for every LP, founder, co-investor, and advisor in your network. Drift alerts before a relationship fades below the point where it matters. Context on every person the moment their name appears in a meeting or deal memo.

📂
Deal Flow Context
Log context on every deal, founder, and conversation in your encrypted vault. Cossi surfaces the right notes before every meeting. Your deal context stays on your device — never in a cloud CRM that a future employee, acquirer, or breach could expose.

Morning Brief
Every morning, Cossi reads you a spoken brief: today's meetings, which relationships are drifting, open follow-ups from last week's portfolio calls, and LP commitments approaching their window. 90 seconds. Before you open your phone.
3 LP relationships flagged this week · Portfolio call with Acme at 11am · Benchmark intro still pending (8 days)

Know who's drifting
before it costs you the deal.

The loop, in a morning

You wake up.
The fund, already handled.

6:45 AM
Brief: LP drift alert + portfolio call context
Sarah Chen (LP, Sequoia Family Office) is 31 days without contact — flagged. Portfolio call with Acme at 11am. Three open follow-ups from the week's portfolio calls. The Benchmark intro is still pending at 8 days. All of this in 90 seconds before you touch email.
7:00 AM
LP reconnect drafted and approved
Cossi drafts a natural, context-aware check-in to Sarah — referencing the last conversation and the fund update naturally, without being formulaic. You approve it in 45 seconds. Before the LP quarterly comes up on their calendar, you've already been in touch.
10:45 AM
Pre-meeting brief: Acme portfolio call
You tap play. Cossi reads the founder context, the last three interactions, the three open diligence items logged after the last call, and the one metric to ask about. You're fully briefed in 90 seconds without opening your notes.
All day
LP data, deal context — all on your device
Your portfolio context, your LP relationships, your deal notes — all computed and stored locally. AES-256-GCM encrypted with a key only you hold. Not in a CRM vendor's database. Not on a cloud provider's servers. On your phone.
“

In this business, your relationships are the fund. They belong on your device, not in someone else's database.

— Built for GPs who treat their network as a long-term asset

🔒
Private by architecture, not by policy

LP names, fund commitments, relationship context, deal flow notes — this is information that could affect fund relationships, regulatory standing, and competitive position if exposed. Cossi stores none of it on a server. The AI runs on-device. The vault uses AES-256-GCM with a key derived from your 24-word seed phrase — no escrow, no vendor recovery path, no breach surface.
