Co-investment has grown from a niche accommodation for favored LPs into a systematic channel that many GPs now manage in parallel with their main fund activity. The growth has outpaced the operational infrastructure. A GP with $10B in flagship fund AUM and $3B in co-investment vehicles is running two parallel businesses with one back-office team, and the co-investment side usually runs on whatever the team can cobble together.
The work is fundamentally structured: opportunity identification, LP interest solicitation, allocation, vehicle formation, and capital deployment. None of this is intellectually novel. The reason it runs on spreadsheets is path dependence, not necessity.
What the workflow actually involves
Working through the typical co-investment cycle, the operationally significant steps are:
Opportunity qualification. A deal emerges that exceeds the flagship fund's allocation capacity or structurally suits co-investment. Someone at the GP qualifies it for co-investment distribution. The decision criteria are often implicit and inconsistently applied.
LP targeting. Which LPs get shown the opportunity? Most GPs have informal LP prioritization — established co-investors, fundraising relationships, LP-specific preferences. This is typically in someone's head or a spreadsheet, not a structured system.
Distribution and expression of interest. The opportunity is shared with selected LPs. LPs express interest with indicative commitments. Expressions typically flow through email with attached teasers. Tracking who received what and who responded is manual.
Allocation. Given total LP interest typically exceeds available allocation, the GP allocates. Allocation logic combines past co-investment history, fund commitments, strategic relationship value, and discretion. Most GPs cannot clearly document their allocation methodology when asked.
Vehicle formation. Co-investment vehicle (typically an LLC or LP) is formed, subscription documents prepared, KYC processed per LP, closings coordinated. This is a compressed version of fund launch mechanics, executed repeatedly.
Capital call and deployment. Capital is drawn from co-investment LPs on closing timeline, aggregated, and deployed into the target. Reconciliation with the main fund's capital call cycle is manual.
- Day 0: Opportunity identified, qualified
- Days 1–3: LP list assembled, teaser prepared
- Days 3–10: Distribution, expression of interest collection
- Days 10–14: Allocation decisions, notification
- Days 14–30: Vehicle formation, subscription documents, KYC
- Days 30–45: Closing, capital call, deployment
Where automation delivers
The opportunity-to-close cycle is compressible substantially with structured workflow, at the operational cost of building it. Four high-value automation areas:
LP preference and history database. Every LP has an implicit profile — deal sizes, sectors, geographies, strategies, historical participation rates. Capturing this explicitly lets the distribution step be targeted automatically rather than assembled from memory. LPs who never participate in a specific strategy stop being sent opportunities they will decline.
Structured interest collection. Expression of interest flows through a portal rather than email. Indicative commitments are captured with structured data rather than freeform text. The GP sees total demand in real time rather than inferring from inbox volume.
Allocation decision support. Allocation can never be fully automated because it involves strategic judgment, but allocation recommendations based on explicit criteria provide a starting point. Documented allocation methodology also protects the GP against LP disputes and, increasingly, regulatory scrutiny.
Vehicle formation and subscription automation. Co-investment vehicle templates, auto-populated subscription documents, reusable LP records — the same automation that applies to main fund subscriptions applies to co-investment vehicles, usually faster to deploy because the structures are simpler.
| Function | Manual baseline | Automated |
|---|---|---|
| LP targeting | Memory + spreadsheet | Structured preference database |
| Interest collection | Portal with structured data capture | |
| Allocation | Ad hoc, undocumented | Criteria-based with judgment layer |
| Vehicle formation | Per-deal legal process | Templated with fund-specific terms |
| Subscription | Paper documents, KYC re-run | Digital with reusable LP record |
| Typical cycle time | 35–45 days | 15–20 days |
The allocation governance question
Allocation is where co-investment programs most often create reputational risk. LPs who feel they should have received allocation and did not complain — sometimes to other LPs, sometimes in regulatory or marketing channels. GPs without documented methodology struggle to defend allocation decisions when questioned.
Good practice involves three elements. First, explicit allocation policy documented at the fund level — the factors considered, their relative weights, the discretionary overlay. Second, allocation records retained per opportunity showing how policy was applied. Third, periodic review of allocation patterns to identify whether stated policy matches actual practice.
This is not just about compliance. LPs increasingly ask about allocation methodology in LP diligence and side letter negotiation. GPs with defensible answers have easier fundraising conversations.
Where to start
For GPs beginning to formalize co-investment operations, the sequencing that tends to work is LP preference database first, then interest collection portal, then vehicle formation automation. Allocation governance runs in parallel rather than as a technology project.
The mistake to avoid is building a full-featured platform before the program has demonstrated scale. Co-investment programs vary enormously across GPs. Building infrastructure before understanding the specific patterns of your program leads to tools that do not match actual use.
For GPs building co-investment infrastructure, the alternative investments capability model maps co-investment against adjacent capabilities like deal sourcing, LP relations, and fund administration — useful for scoping where the operational investment connects to existing GP capability versus where it represents new build.
