Growth Partner retainer — senior developers embedded on your product. Features, fixes, conversion, scale. From $5,000/month.

## Your product evolves monthly, without hiring a full team

After your MVP launches, you need ongoing engineering: new features, onboarding improvements, billing, admin tools, performance. Our Growth Partner retainer is a senior developer partnership, not a ticket queue.

## How a month works

### Week 1: Growth map

We agree the one metric to move this month (activation, conversion, retention) and the features and fixes that move it.

### Weeks 2–4: Ship

2–3 high-impact features, unlimited bug fixes and performance work, deployed as they are ready.

### Ongoing: Optimise

Speed, onboarding, conversion and retention improvements on the paths your users actually take.

### Month end: Review

What shipped, what improved, what broke, and what is next. Then we plan the following month.

## Retainer vs hiring

|  | Growth Partner | Hiring in-house | Freelancers |
|---|---|---|---|
| **Start** | No recruiting | Months of recruiting | Days to weeks |
| **Seniority** | Senior only | Depends on budget | Varies |
| **Product decisions** | We own tech, deployment and prioritisation | You manage the team | You manage each person |
| **Commitment** | 7 days notice | Salary, equity, notice periods | Per project |
