## Description

The Viral Coefficient Calculator is a specialized tool for analyzing product virality. It helps you figure out if your product is actually growing through word of mouth or if you're just spinning your wheels. It takes your referral data and turns it into hard numbers like your K-factor and growth classification. Instead of guessing if your loops are working, you can get a clear picture of your growth status, whether it's sub-critical or full-blown viral. You'll also see exactly how many cycles it takes to double your user base and get a projected roadmap of your expansion. This Connector lets your agent handle the heavy lifting of growth modeling so you can focus on the strategy. It's a core part of the Vinkius ecosystem for anyone who needs to move past "vibe-based" marketing and into data-backed growth. You can feed in data about how many invites are sent, the conversion rates of those invites, and the resulting growth cycles. This turns a messy spreadsheet into a clean projection. By having your agent do the math, you can spend your time on the creative side of marketing. You'll get a clear view of what's working and what isn't, allowing you to double down on the features that actually drive new signups. The K-factor is the primary metric for understanding if your growth is self-sustaining. If it's above 1, each user is bringing in more than one new user, which is the holy grail of growth. This tool helps you calculate that number accurately from your raw referral data. It removes the guesswork from your growth cycle analysis.

## Tools

### estimate_doubling_period
Estimate doubling period to find the number of cycles needed to double your user base. This helps you set concrete milestones for your growth team.

### evaluate_virality
Evaluate virality to classify your growth as Sub-critical, Critical, or Viral. It provides a clear K-factor to measure your referral loop efficiency.

### forecast_growth_trajectory
Forecast growth trajectory to project your user base expansion over a specified number of future cycles. This gives you a data-backed roadmap for your marketing goals.

## Prompt Examples

**Prompt:** 
```
My users send 10 invites and 5% of them sign up. What's my status?
```

**Response:** 
```
Based on those numbers, here is your growth analysis:

* **K-factor:** 0.5
* **Growth Status:** Sub-critical

**What this means:** Your current viral loop isn't self-sustaining. Each user is bringing in fewer than one new user, so you'll need to increase your invite volume or conversion rate to hit a viral state.
```

**Prompt:** 
```
How many cycles do I need to double my users if my K-factor is 1.2?
```

**Response:** 
```
To reach twice your current user base with a K-factor of 1.2, you will need approximately **4 full growth cycles**. 

This assumes your current conversion and invite rates remain steady as you scale.
```

**Prompt:** 
```
Forecast my growth for the next 3 cycles starting with 1000 users and a K-factor of 1.5.
```

**Response:** 
```
Here is your projected growth trajectory for the next 3 cycles:

| Cycle | Projected User Base |
| :--- | :--- |
| **Cycle 1** | 2,500 |
| **Cycle 2** | 6,250 |
| **Cycle 3** | 15,625 |

*Note: These projections assume your K-factor remains constant at 1.5.*
```

## Capabilities

### Classify growth status
Evaluate virality to determine if your growth is Sub-critical, Critical, or Viral.

### Calculate K-factor
Use the K-factor metric to measure the efficiency of your current viral loops.

### Predict doubling periods
Estimate doubling period to see how many cycles it takes to double your user base.

### Project growth trajectories
Forecast growth trajectory to see your projected user expansion over future cycles.

### Analyze viral loops
Analyze the mechanics of your referral loops to identify where growth is stalling.

## Use Cases

### Viral Loop Audit
A marketer wants to see if a new referral program is working. They ask the agent to evaluate the virality of the current loop.

### Board Reporting
A founder needs to show the board a 6-month projection. They use the tool to forecast the growth trajectory based on current K-factors.

### KPI Setting
A product manager needs to know when the user base will hit 10k. They use the doubling period tool to set a concrete deadline.

### A/B Testing Rewards
A growth hacker tests two different invite rewards. They compare the K-factors from both to see which one performs better.

## Benefits

- Get a clear growth classification using evaluate_virality to see if your referral loop is actually working.
- Stop guessing your timeline with estimate_doubling_period to find out exactly how many cycles it takes to double your users.
- Map out your future growth with forecast_growth_trajectory to give stakeholders a data-backed roadmap.
- Identify your K-factor quickly to understand the efficiency of your current invite system.
- Move away from vibe-based marketing by using hard numbers to justify your growth strategy.

## How It Works

The bottom line is you get a data-backed growth roadmap instead of just guessing your virality.

1. Provide your agent with raw referral data like invites sent and conversion rates.
2. The agent uses the Connector to calculate your K-factor and current growth classification.
3. You get a data-backed projection of your user base expansion and doubling timeline.

## Frequently Asked Questions

**How does the Viral Coefficient Calculator help my growth marketing?**
It turns your raw referral data into actionable growth projections. You get a clear K-factor and a growth classification, helping you see if your loops are actually working or if you need to adjust your strategy.

**What is a K-factor in viral marketing?**
The K-factor is the number of new users each existing user brings in. A K-factor of 1.0 means every user brings in exactly one new user, making your growth self-sustaining. This Connector calculates that number for you.

**Can the Viral Coefficient Calculator predict my user base growth?**
Yes, it can project your user base expansion over a specified number of future cycles. It uses your current K-factor to build a data-backed roadmap of your growth trajectory.

**How do I know if my product is actually going viral?**
The Viral Coefficient Calculator evaluates your growth status and classifies it as Sub-critical, Critical, or Viral. It takes the guesswork out of the equation by using your actual referral metrics.

**Can I use the Viral Coefficient Calculator for different marketing channels?**
Yes, you can use it to analyze any referral-based loop, whether it's a friend invite system, a shared link, or any other mechanism where users bring in new signups.

**What is the K-factor?**
The K-factor (Viral Coefficient) represents the average number of new users generated by a single existing user. It is calculated by multiplying the average number of invitations sent per user by the conversion rate of those invitees.

**How do I know if my product is viral?**
A K-factor greater than 1 indicates exponential growth (Viral). A K-factor of exactly 1 represents steady, linear growth (Critical), and a K-factor below 1 means the viral loop will eventually stop without external input (Sub-critical).

**Can I project future user growth?**
Yes, by using the `forecast_growth_trajectory` tool, you can simulate and view the projected total user population for a specific number of future growth cycles.
