From Comment to Chrome Extension

A LinkedIn CRM Integration Built with Blitzy
My development story started with a comment in a sales meeting.
The sales team was discussing their current workflow: what's working, what isn't, and possible bottlenecks in the cycle to address.
At Blitzy, like many other companies, software is an integral part of organizing and maintaining customer relationships. Acknowledging technology's role in creating efficiency for the sales cycle, Matt, a sales representative, offhandedly mentioned an idea for an internal feature to streamline their workflow.
Inspired by Apollo's Chrome Extension, a Blitzy-internal feature where sales reps could click a button on a LinkedIn profile to instantly add someone's enriched contact data to the CRM would accelerate productivity considerably. Without functionality like this, sales reps could spend 25% of their work week doing administrative tasks like updating contact information, data entry and CRM hygiene.
I told Matt I could probably build it.
That weekend, I did.
Identifying Feature Scope
Before jumping into any code, I needed to understand the technical requirements. I opened a conversation with Claude to help me break down what the extension would need based on the sales team's feedback.
Here's what I came up with:
- A content script to inject a button on LinkedIn profiles
- A backend to handle CRM writes and contact enrichment
- An authentication layer so each rep could use it securely
I drafted a prompt thorough enough for Blitzy to take on the full project in a single run. The prompt covered the Chrome extension scaffolding, LinkedIn DOM integration points, backend API design, and the CRM data model.
What Blitzy Built
I submitted my prompt to Blitzy on Wednesday night. After two days, code generation was complete.
When the run finished, I spent Saturday afternoon QA testing the button placement on LinkedIn. The extension needed to inject a clean, intuitive button directly onto profile pages without breaking LinkedIn's existing layout. I found a couple of issues with positioning and fixed them up.
From there, I built out the backend, connected the CRM and Clay integrations, and had the whole thing up and running.
The button is depicted below:

Click the purple "Enrich" button on any LinkedIn profile, and a contact is created in our CRM with enriched data from Clay. A corresponding Slack message is sent to the sales rep with the enriched data enclosed.
A Blitzy Refinement Run
The extension worked... until I invited other team members. The onboarding flow was not functional.
Rather than spending hours manually debugging the damage, I ran a refinement through Blitzy. The platform holds the full context of our codebase and understands the relationships between edge functions, the authentication layer, and the extension logic. Blitzy identified and resolved all the issues.
The extension worked!
I was able to send out invites, onboard my reps, and get the team using it right away. The Chrome extension is live and used across the Blitzy sales team.
Why This Matters
The whole project, from a passing comment in a sales meeting to a production Chrome extension used daily by the team, took a weekend of hands-on time. Blitzy handled the engineering effort.
There is a meaningful difference between a copilot and an autonomous development platform like Blitzy. A copilot would have required me to sit in a code editor and manage every integration point manually. With Blitzy, I submitted a prompt, went about my Saturday, and came back to a working Chrome extension. When things broke, the platform fixed that too.
The Chrome extension was not a proof of concept. What I built solves a real problem for the sales team, saving each sales rep on average eight to twelve hours a week.
Features like my extension could sit in a backlog for months, waiting for engineering bandwidth to make the project feasible. Blitzy made it possible to act on the idea immediately, building and shipping a solution in days.
What is sitting in your backlog that could be built this weekend?
