SpartanFlow

Cold outbound platform for IT MSPs and staffing agencies. Built on Next.js and Supabase. Started as six fragile n8n workflows with a Google Sheet pretending to be a database. Now it's a single dashboard with its own experiment engine. Still adding features.

Daily Outreach Agent

Runs daily · 100% automated

A Claude Co-Work agent that runs my job search every morning. Searches 11 job titles, researches each company, pulls 2 contacts per role, verifies emails through a Prospeo → Hunter → Apollo → Reoon cascade, and drafts outreach in my voice. Sends between 7 and 8 AM. Checks for bounces an hour later.

A bit of background
Hari Rajashekar

I build growth systems. Cold outbound, voice agents, internal CRMs — whatever moves pipeline for a B2B company. Before running my own products, I was at Accenture and Level 11 Technology building automation for enterprise clients.

Most of what I build solves a problem I had first. Then I clean it up enough to hand it to someone else. The point is figuring. Not figured out.
