Built for Partners & GPs

Relationship capital.
Protected.

You manage portfolio relationships, LP communications, and deal flow context across 200+ people. None of it should live in a CRM someone else controls. Cossi runs the intelligence layer on your device — encrypted, private, and recoverable only by you.

Free to start. Pro features from $9.99/mo.

The problem

Your edge is your network.
Your network is in someone else's cloud.

Your deal flow, your LP relationships, your portfolio context, your co-investor network — these are among the most valuable and sensitive assets in your fund. And right now, most of it lives in a CRM, a notes app, or a productivity tool that stores your data on servers you don't control, can't audit, and can't protect from breach or subpoena.

Cossi stores your relationship intelligence on your device. Encrypted with keys only you hold. No CRM vendor. No cloud. No data policy you have to hope they honour.

How it works

The three things GPs
use Cossi for every day.

Relationship intelligence for a 200+ person network. Deal flow context at the moment you need it. LP communications that stay private.

👥

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.

A partner's morning

Walk into every meeting
with full context.

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.

🔒

LP data that never touches a server

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.
