Custom development

A custom tool is an interactive feature developed specifically for your website, designed to engage visitors and convert them into qualified leads. Unlike a standard contact form, a custom tool provides immediate value to the user: a personalized result, an estimate, a diagnosis, or a score. It's this value exchange that dramatically boosts conversion rates.

The most common custom tools: ROI calculators, price calculators, multi-step forms, qualification quizzes, interactive lead magnets, product configurators.

At Gemeos, we develop four main categories of tools, all directly integrable into Webflow.

We have developed this type of tool for Moment Lab (gamified slot machine for lead capture) and Homunity (real estate investment simulator). In both cases, the engagement rate of pages equipped with these tools was significantly higher than pages without interactive tools.

The price depends on the complexity of the business logic, the design level, and the required integrations. A well-designed multi-step form is less complex to develop than a financial simulator with dynamic calculations and multiple scenarios.

These ranges include design, Webflow development, and basic CRM integration. Price variations are mainly due to the complexity of conditional logic and the number of result scenarios to manage.

Yes, it's even essential. A custom tool without CRM integration generates data that remains on the site without feeding your sales pipeline. Every lead captured by the tool must arrive in your CRM with its qualification data: quiz answers, simulator parameters, score obtained.

We also systematically configure UTM tracking on submissions: every lead entering the CRM is tagged with its source, medium, and campaign. You know exactly which channel generated which lead via which tool.

A classic lead magnet (ebook, PDF guide, checklist) exchanges content for an email. The problem: perceived value is increasingly low, conversion rates are eroding, and the lead provides no information about their actual needs.

An interactive tool generates personalized value in real-time: a result specific to the visitor's situation. This mechanism yields significantly higher conversion rates and infinitely better-qualified leads, because the answers provided during the journey precisely reveal the prospect's context and maturity level.

All sectors where the purchasing decision involves personal variables benefit massively from interactive tools. The more difficult it is to quantify the value proposition without context, the more a simulator or calculator makes a difference.

This is exactly the positioning we're developing at Gemeos in the Finance sector: investment simulators for wealth managers (CGP) and family offices, yield calculators for fintech platforms, and qualification tools for private wealth management firms.

Yes, and it's even part of our approach. A custom tool behaves like a product: it optimizes itself based on usage data. The first few weeks after launch often reveal friction points in the user journey or result scenarios that need refinement.

We systematically recommend an optimization cycle 4 to 6 weeks after launch: analysis of completion rates per step, identification of abandonment points, UX adjustments, and calculation logic if necessary. This cycle is included in our custom tool projects, or available on retainer if you desire continuous optimization.
