The Private Equity Tech Stack: What GPs Are Actually Running

Every PE firm has a tech stack. Most have a more expensive one than they need, a less integrated one than they think, and at least two subscriptions that nobody uses but nobody cancels because "someone might need it." This is a frank inventory of what the layers actually look like — what gets deployed, what gets shelved, and what the emerging AI tier is doing to the whole picture.

Layer 1: CRM and Relationship Management

The CRM layer manages deal pipeline, LP relationships, and network contacts. The dominant players: DealCloud (purpose-built for PE/VC, $50K–$150K/yr), Affinity (relationship intelligence, $2K–$6K/month), 4Degrees (AI-driven relationship scoring, mid-market pricing), and Salesforce (dominant in larger shops, complex to configure for PE, expensive).

The honest reality: most LMM funds are using one of these tools at 30% of its capability. CRM adoption fails when it requires manual data entry. The firms getting value from DealCloud and Affinity are the ones that have configured automatic email sync and contact enrichment — so the system updates itself rather than requiring a weekly manual data entry session nobody does.

Layer 2: Portfolio Monitoring

Chronograph and Visible dominate the mid-market. Chronograph is more robust for PE-specific portfolio analytics; Visible is more accessible for funds that also want an LP-facing reporting layer. Causal is gaining traction for financial modeling and scenario analysis at the portco level. Larger funds run custom-built dashboards or enterprise tools like Addepar.

The monitoring layer is often the most underused. Firms buy portfolio monitoring software and then still collect portco data via email every quarter. The firms that get value connect the tool directly to portco accounting systems (QuickBooks, NetSuite) and set up automated data pulls — turning the platform into a real-time dashboard rather than a quarterly data entry exercise.

Layer 3: Fund Administration and Accounting

Fund admin is where the critical financial records live: capital accounts, waterfall calculations, carried interest, fee calculations, K-1 preparation. The major platforms: Allvue (enterprise, $80K–$300K/yr), Juniper Square (mid-market, $30K–$80K/yr), and a significant number of LMM funds still on Excel with an outsourced fund administrator doing the reconciliation.

Outsourced fund administration is underrated as an option. For a $100M fund with two people in back-office, paying $3K–$8K per month to an established fund admin firm like Citco, SS&C, or a boutique administrator often beats the combined cost and complexity of running Allvue in-house.

Layer 4: LP Portal and Investor Communications

The LP portal is how LPs access their statements, capital call notices, K-1s, and quarterly reports. Juniper Square dominates this layer in mid-market. Anduin is gaining share for subscription processing. Dynamo covers the full CRM-through-LP portal stack for larger funds.

Layer 5: Data Room and Document Management

For deal due diligence: Datasite (formerly Merrill DataSite) and Intralinks are the enterprise standards. Firmex and Box work well for smaller deals. For internal document management, SharePoint is common at larger firms; Dropbox and Google Drive are common at smaller ones — with all the version control problems that implies.

Layer 6: The Emerging AI Tier

This layer is being built right now, primarily on top of existing infrastructure rather than replacing it. The use cases that have moved from pilot to production: LP report narrative generation, CIM screening and summarization, contract review in due diligence, and portfolio monitoring commentary. The use cases still in pilot: deal sourcing automation, management assessment support, and predictive portfolio analytics.

The firms building this layer in-house are getting a meaningful operational advantage today — because enterprise vendors won't have it bundled into standard packages for another 18–24 months.

What the Average LMM Stack Actually Costs

A reasonable all-in technology budget for a $150M LMM PE fund:

• CRM (Affinity or 4Degrees): $30K–$60K/yr
• Portfolio monitoring (Visible or Chronograph Starter): $12K–$30K/yr
• Fund admin (outsourced): $36K–$96K/yr
• LP portal (Juniper Square Starter): $30K–$50K/yr
• Data room (deal-based pricing): $5K–$20K/yr depending on deal volume
• AI reporting layer: $10K–$25K/yr

Total: $123K–$281K per year. At 1% management fees on $150M, that's $1.5M in annual fee revenue against $123K–$281K in technology spend — roughly 8–19% of fees. The firms running lean stay closer to the low end without sacrificing quality; the firms that over-invest in enterprise software often find themselves at the high end with lower actual utilization.
