Systems I run marketing on
Most of these I built with AI coding agents and workflow tools. The tag on each says what I did.
Product marketing delivery tracker
Every product marketing ask, from launch videos to positioning audits and review-site and website messaging, is a tracked task. Engineering work that PMMs coordinate runs through it too, and a bot checks the live site before anything is marked done.
Built by me
Organic traffic monitor
Reads our search data every two weeks and writes up what changed in how buyers find us.
Designed and run by me
Competitive intelligence
Every Monday it reads competitors' sitemaps and reports what they shipped.
Built by me
Competitor conversation tracker
Finds social posts about competitors, judges which ones matter, and routes each to the PMM who owns that product line.
Designed by me
CRM re-engagement
Groups CRM accounts that sales hadn't contacted in years by the products they tried, and writes the emails for each group. It's sending now.
Built by me
Backlink and brand-mention audit
A multi-agent audit that scores sites for backlink and brand-mention outreach and picks the route to take with each.
Built by me
This website
A claim ledger ties each number to its source, and a design gate checks every page at four screen widths before it ships.

About me
I'm Harshit Paul. I started as a Salesforce developer, which is why I think in systems, funnels and data before I think in copy.
I have spent eight years building marketing at one B2B SaaS company in developer tools and AI, from its founding stage: five roles, a 20+ person team, 14 launches and one rebrand. I like engines that compound: positioning, product-led growth and activation sequences that grow revenue without growing headcount at the same rate.
Since 2026 I also run sales enablement, alongside product marketing.
