A growth agency that only gets paid on results, with a site that proves the model in charts before anyone books a call.

## Challenge

Growthacker, the growth agency of PT Celebes Niaga Jaya, founded in Indonesia in 2022, helps service businesses (SaaS, consulting, education, health and wellness, professional services) build, sell and scale subscription models in Indonesia, the United States, Singapore and Malaysia. Its offer is unusual: no upfront, hourly or project fees, only a 10% commission on the recurring revenue from new clients it brings in, capped at $6,250 a month. A buyer used to retainers needs to see how that works before trusting it: what the agency actually does, how attribution across six ad platforms changes the picture, what a subscription could earn, and how the model compares with hiring a team or an agency. The same answers also had to reach AI assistants, which increasingly do the first round of vendor research.

## Solution

The site is an editorial page on warm paper, with Newsreader headlines whose italic word rotates through revenue, growth, sales and profit, Geist for everything else, and one blue that carries every chart. It argues with live components instead of claims: a 24-month revenue chart that draws itself, shows the $0 period before first results and the 10% fee line after; an attribution card that switches one customer's six-platform journey between Unified and Last click; three discipline tabs with their own funnel, channel and recommendation charts; a four-step process; pricing in USD or IDR; a revenue calculator that projects recurring revenue and the commission from a price, a retention and new clients a month; and a comparison table against an in-house team and a retained agency across seven categories. A quote from KYZN's Chief Commercial Officer, an FAQ, a searchable FAQ page and a contact page with email, WhatsApp and the registered office complete the route to a free discovery call. For agents, the same content is published as a keyless REST API with an OpenAPI 3.1 spec, a stateless MCP server, WebMCP tools registered on every page, markdown versions of each page, llms.txt and an agent skill.

## Technology

The site is a TanStack app served through Cloudflare, with every chart drawn in the browser from the same data the API returns. The public API at growthacker.id/api/v1 exposes eight read-only operations (company, services, pricing, revenue projection, FAQs, comparison, contact and health) with no authentication, and the MCP endpoint at growthacker.id/mcp offers the same seven tools over streamable HTTP. [To confirm: framework version and hosting plan.]

## Result

growthacker.id, with web development and UI/UX design by goodtogrid, explains a performance-based pricing model with working charts and a calculator, and is readable by people and by AI agents through the same content. [To confirm: goodtogrid's scope on the Growthacker site and the agent-access layer.] The page argues with live components instead of claims: a 24-month revenue chart that shows the $0 period before first results and the 10% fee line after, an attribution card that switches one customer's six-platform journey between Unified and Last click, pricing in USD or IDR, a revenue calculator that projects recurring revenue and the commission, and a comparison against an in-house team and a retained agency across seven categories. Agents get the same content through a keyless REST API with an OpenAPI 3.1 spec, an MCP server, WebMCP tools on every page and llms.txt.

- Live at growthacker.id
- Seven interactive components, from the revenue chart to the comparison table, each with its own Replay or control
- One content source served as pages, markdown, a REST API, an MCP server and WebMCP tools
- [To confirm] Discovery calls booked through the site

Status as of October 2026.
