From PDF to a live, interactive ROI calculator in under 2 weeks.

Nectar Edge builds infrastructure that runs complex AI models with sub-20ms latency, 30x cheaper than cloud. Two weeks before the Edge Agent Challenge event (NVIDIA and Intel in attendance), their primary sales asset was still a PDF. They needed a website that would convince skeptical AI developers and VCs. We shipped one, with a custom JavaScript ROI calculator as the centerpiece, on time for the event.

From PDF to a live, interactive ROI calculator in under 2 weeks.

Challenge

Nectar Edge had an abstract value prop: “10x faster, 30x cheaper than cloud.” Telling a skeptical AI developer that earns nothing on its own. They needed to prove it. Translate the physics into dollars. Make it interactive enough that the user couldn’t argue with it. All before a launch event that wouldn’t wait.
Client:
Nectar Edge
Industry:
Edge AI
Location:
CA, USA

Approach

The calculator is the whole sales pitch.

Three sliders and one toggle. The user picks their GPU hours, latency requirement, and cloud vs. edge. The calculator tells them in real time how many dollars they save and how much faster their AI agent runs. The math is theirs. The conclusion is unavoidable. The interactive tool replaces a 30-minute pitch.

We hand-coded the calculator because Webflow couldn’t ship it.

The client had prototyped the math in GPT. Webflow’s native logic can’t run that. We rewrote the entire formula in vanilla JavaScript, hooked it to the sliders with smooth real-time updates, and built it light enough to feel instant. Custom code on a Webflow site only where Webflow itself can’t do the job.

The design speaks to engineers.

Nectar’s audience lives in the terminal. So the site lives there too. Dark theme, electric lime accent, sharp monospace-influenced typography, GSAP-powered micro-interactions on every interactive element, and a custom Swiper.js headline scroller in the hero. Polished without being precious.

The calculator captures leads silently.

Behind the scenes, the slider inputs (GPU hours, especially) push into a hidden form field on the contact form. A high GPU-hours user shows different intent than a low one, and the sales team sees that signal automatically. The interactive tool is a sales weapon and a lead qualifier in the same component.

Shipped under chaos.

A two-week deadline. An asynchronous client. A formula being refined in parallel. We absorbed it. The site launched on the day the Edge Agent Challenge opened, with NVIDIA and Intel reps in the room. The website was the booth.

Before / After

Before

  • Idea locked in a complex PDF
  • Unclear value for investors and partners
  • Risk of blowing a critical launch event
  • No way to capture lead intent

After

  • Interactive tool that sells the product on its own
  • Concrete cost-and-speed proof users can run themselves
  • Website launched on time, becoming the core GTM asset
  • Hidden form fields capturing GPU-hours signal for sales qualification

If your value prop needs three slides to land, build a calculator instead.

Abstract value props die in pitch decks. Interactive tools that let the buyer prove the value to themselves close deals. We’ve built ROI calculators, interactive comparisons, and value-prop simulators that turn a complex argument into a single screen. Tell us what you’re trying to prove.
