Show LPs your fund math adds up.
For Fund I and II managers preparing the next raise. Check how ownership, reserves, company count and team capacity fit together against public fund data, lock the plan at first close, and show LPs that Fund I followed it. Architecture examines how a fund is built; it does not predict, rate or guarantee outcomes.
See how your fund’s choices fit together.

You know your fund's numbers.
But do your choices fit together?
A Series A focus and a fifteen percent ownership target can quietly pull against each other.
Architecture is informed by Colibrí Institute research, including a study of 2,142 funds.
Say hello to Colibrí Architecture, the VC operating system.
Architecture helps you design your fund, test every new investment against it, and report to your LPs.
Fund Design lets you edit every lever, from fund size to reserves, while eleven checks show where your choices conflict.
Decision Support shows how each new investment moves the portfolio, before you commit.
Scenario Engine gives every active position a recommended follow-on check and a timing signal.
LP Memo gives you a starting point for your quarterly letter, drafted from your dashboard.
And with Practice, Firm Overview puts every fund side by side, with concentration and efficiency across the firm.
You know your fund's numbers. Now you know how they fit together.

Three engines, three questions.
Start with three questions: does the fund’s capital math work, can the firm carry its strategy, and where does exposure overlap? Each engine examines a different part of the picture. Practice brings their readings together in the firm-level Architecture Score.
Portfolio Efficiency.
Do the fund's capital, ownership and portfolio targets fit together?
See how fund size, reserves and planned investments line up with ownership targets and team capacity. The reading takes your firm’s lifecycle stage into account.
Firm Design Congruence.
Do the firm's structural choices fit together?
Eleven checks examine choices such as investment committee voting, board responsibilities and succession planning. When two choices create friction under the model, the result names the tension and explains why it merits review.
Cross-Fund Concentration.
Where do your funds share exposure?
The engine reads across every fund the firm operates and flags the concentration patterns that no single fund-level view can catch, including sector concentration and single-company exposure that accumulates over time.
The model uses lifecycle stages to put configuration choices in context: Conviction for an early firm, Cadence as it builds a repeatable way of working, and Continuity as it plans for an enduring institution. These are model reference frames, not predictions of performance.
Read the methodology →Move from the firm view to the next decision.
Review the firm, look closely at a fund, or work through a follow-on decision. Each view explains the relevant model reading. Where a score has a valid cohort reference, its comparison is shown with the appropriate empirical or provisional context.
Every fund in your firm, in one view.
The Firm Overview brings every fund the firm operates into a single cross-fund analytical view. The composite Architecture Score sits at the top, the three engine scores break down underneath, and the firm-level aggregates (total committed capital, total portfolio companies, weighted average GP load) sit alongside.
- The Architecture Score and its five interpretive bands, computed for the firm overall
- Cross-fund concentration patterns surfaced as flags worth reviewing
- A weighted firm-level Composite Efficiency Index that integrates each fund by deployed capital
- Per-fund cards sorted by vintage, with one-click navigation into any fund
Firm Overview
Live configuration analysis, per fund.
The Fund Overview brings the fund’s design and deployment into one view. The Composite Efficiency Index shows how its configuration fits together, with lifecycle context where available. Firm Design Congruence, capital per GP, reserves and follow-ons help you work back from a reading to the choices behind it. Supporting model measures are separate from observed performance and do not forecast realized returns.
- A live Composite Efficiency Index that recomputes as configuration changes
- Lifecycle-matched references, labeled when provisional
- Configuration Congruence showing the eleven structural checks the engine ran
- Capital deployment, follow-ons, and reserves at a glance
Colibrí Demo Fund II
The follow-on decision, structured.
The Scenario Engine is the companion module that helps you think through a specific follow-on allocation. For a chosen portfolio company, it reads the trajectory, the proposed round, the available reserves, and the firm's cross-fund exposure, and returns a recommendation, a recommended allocation in dollars and as a share of pro-rata, a timing signal, and a three-part rationale that names what is driving the call.
- An Outlier Probability Score that reads MOIC trajectory, valuation step-ups, and stage progression
- A conviction allocation curve calibrated separately for each lifecycle stage
- Reserve and concentration constraints surfaced as binding factors when they limit the recommendation
- Decision-support, not automation; you remain the one making the underlying call
Evidence you can show an LP.
Architecture’s benchmarks come from public fund filings, fund results published by public pension and endowment LPs, and published research. Every number shows its source and whether it is measured or a design rule.
The methodology explains which readings are benchmarks, which are design rules and what a reading cannot tell you. Colibrí Institute’s research informs the questions; the platform supplies the checks.
A firm’s stage changes the context.
A first fund and a multi-generational firm carry different demands. Architecture uses Conviction, Cadence and Continuity as lifecycle reference frames when it examines how a firm is configured.
The downside deserves a plan too.
In fund results published by public LPs for 206 mature venture funds from vintages 1990 to 2016, about a quarter returned less than 1.0x. Architecture reads company count, ownership and reserves together, so the plan you show LPs accounts for the companies that will not return capital.
You can examine the design before the outcomes arrive.
You do not need to wait for exits to check whether the fund’s choices fit together. Once the required inputs are complete, Architecture can examine the configuration. That reading supports judgment; it does not establish what the fund will return.
Useful from your first fund to a firm with several.
Architecture works for any venture firm, from a first-fund Conviction firm to a multi-fund Continuity firm. The model calibrates to your lifecycle stage and your firm structure rather than forcing you into a generic template.
Single-fund GPs.
Foundation brings your fund’s capital math, portfolio targets and firm design into a single working view. Review configuration readings and the tensions behind them, then use the Scenario Engine to explore follow-ons in existing positions.
- Composite Efficiency Index with live cohort context
- Firm Design Congruence Score with a ranked tensions list
- Configuration recomputes in real time as you adjust levers
- Scenario Engine for follow-on allocation decisions on existing positions
Multi-fund GPs.
Practice adds the firm-wide view. See how sector and company exposure accumulate across funds, review the composite Architecture Score, and move into an individual fund when a reading needs closer attention.
- Firm Overview with one composite Architecture Score across every fund
- Cross-fund sector and single-company exposure surfaced as flags
- Weighted firm-level Composite Efficiency Index across all funds
- Per-fund drill-down to every score the platform produces
Show LPs the plan held.
Check your fund math on the Free plan with no card required, or take the tour to see the views first. Foundation and Practice add the Scenario Engine, LP memos and firm-wide views, and each offers a seven-day trial that requires a card.
Things GPs ask before they sign up.
Here are the practical details to know before you begin. The methodology goes deeper into the model, and you can contact us if your question is not covered.
What is Colibrí Architecture, in one paragraph?
Colibrí Architecture helps venture GPs examine how a fund’s capital, ownership, reserves and portfolio targets fit the firm’s capacity and structure. Foundation covers fund-level analysis and follow-on decision support. Practice adds cross-fund analysis and the composite Architecture Score. The readings help you examine choices; they do not forecast realized returns.
Who is the platform built for?
The platform is built for the general partners running venture capital firms, from single-fund Conviction firms through multi-fund Continuity firms. The model is calibrated separately for each lifecycle stage, which means the experience is tuned to the kind of firm you actually run rather than forcing you into a generic template that assumes every firm looks like every other firm.
What does the free trial include?
Your seven-day trial includes the features of the plan you choose. Both plans include fund analysis, score history and the Scenario Engine. Practice also includes Cross-Fund Concentration and the firm-level Architecture Score. A card is required for the trial, and billing begins after it ends unless you cancel first.
What data do I need to get started?
The platform requires fund-level configuration (fund size, target portfolio count, target ownership, investment period, reserve allocation, target stage, industry scope, geography, team size, GP count, and a few related fields) along with basic investment-level data once you start logging your portfolio. Have those figures ready before you begin. Scores become available as the required inputs are completed; you can add investment records over time.
The platform does not require fund admin integrations or sensitive financial data to compute its scores. Cap tables, capital calls, LP statements, and other operational data sit outside what the model reads.
Is my data private?
Your firm’s records are restricted to its authorized users and to the service access described in the privacy policy. Cohort references use aggregated data. Your scenario history is firm-private and does not contribute to other firms’ calibration without the explicit opt-in described in that policy. Read the privacy policy for research use, service providers and deletion requests.
How is the methodology developed?
The methodology is grounded in research from the Colibrí Institute and is documented in a versioned specification that serves as the source of truth for every score the platform produces. The methodology is independent of any external scoring framework and is proprietary to Colibrí Strategies. As the platform accumulates user data, thresholds and weights may be revised against empirical distributions, with every revision producing a version increment of the methodology document.
The full methodology page walks through what each engine evaluates, the eleven firm design checks, the lifecycle framing, and the complete definitions glossary.
How is this different from a spreadsheet or a BI tool?
Architecture gives you a defined model for examining how the fund and firm fit together. Its checks connect choices that might otherwise sit in separate sheets: ownership and portfolio size, reserves and follow-ons, board responsibilities and team capacity. You can trace a reading back to its inputs and revisit it as the firm changes.
Does this replace my fund administrator?
No. The platform does not replace your fund administrator and does not process capital calls, distributions, partner allocations, or LP statements. Architecture sits alongside your existing operational stack as the analytical layer that reads how your firm is built, and it integrates with the rest of your operations through the data you choose to bring in rather than through direct integrations with fund admin systems.
Can I use the platform if I only have one fund?
Yes. Foundation is designed for one fund and includes Portfolio Efficiency, Firm Design Congruence and the Scenario Engine. The firm-wide Architecture Score and Cross-Fund Concentration are Practice features; they are not included in Foundation simply because the model can compute them.
What does the platform cost?
The Free plan models one fund at no cost, with no card and no expiry. Foundation adds the Scenario Engine, LP memos and a second seat for a single fund; Practice adds multi-fund and firm-wide features. Both paid plans are available with annual or monthly billing, and each has a separate seven-day trial option. The pricing page shows the current prices, inclusions and entry paths.
How long does setup take?
Setup time depends on how much data you have ready and how many funds and investments you enter. Start with the fund and firm configuration; the relevant scores appear when their required inputs are complete. You can save your place and return to add investment records later.
