One line of tag, on any siteforms

FormNest is a no-code form-building platform built around a form / survey SDK that embeds into any existing site with a single line of tag. Even non-engineers can publish a form in minutes and manage collected data securely in one place.

The story of launching a new platform, built in-house from scratch, to solve the challenges of “development required for every installation, non-engineers unable to touch it, and environment setup depending on individuals.”

CLIENT
About you

Growstack Co., Ltd., a leader in digital marketing.

A marketing company that handles a large volume of inquiry capture and survey collection across websites. Feeling the limits of building forms individually for each client site, they decided to develop a reusable form platform in-house.

The goal: build a form platform “anyone can install, on any site, instantly” from scratch, while simultaneously achieving centralized management of collected data and automated cloud operations.

CHALLENGE
Design challenges to solve

Four design challenges hindering growth.

Every site installation required development

Front-end implementation arose for each project,Launch delayedwas the norm.

Non-engineers can’t edit forms

Even wording and field changesDevelopment requested each time, stalling operations.

Collected data stored in scattered locations

Management split per site,Aggregation & analysis difficultwas the case.

Environment setup depends on individuals

With manual setupRisk of environment discrepancieswere a burden.

ARCHITECTURE
The architecture we built together

Four platforms, built in-house from scratch.

An embeddable SDK, no-code builder, publishing-management CMS, and data-collection API — all built in-house from scratch without ever stopping the service. The cloud infrastructure codifies every environment, achieving highly reproducible operations.
