Hi, I'm Sid.

I do performance marketing rooted in consumer psychology.

Most marketing today feels AI-generated: same tone, same phrasing, same predictable feel.

I care about using AI to work faster, but even more about the psychology behind why someone actually decides to buy. That's the part AI still can't fake. With seven years of experience, I help your business run at 100% of its capacity.

How I work

Same lens, never the same plan.

No two accounts get the same playbook. But every project runs through the same four lenses, adapted to what your business actually needs.

01 · Diagnose

Research & Insights

Before making any adjustments, a deep dive into your account is necessary. I dig into the current state, the configuration, the customer journey and the data behind it.

02 · Build

Build & Launch

I build a strategy around your core problem. Campaigns, flows and content are then built around what your data actually says. Everything gets tracked for proper analysis.

03 · Learn

Test & Report

Every aspect is tested and reported to you, on the frequency you choose. You get all the data so you're never feeling out of control.

04 · Compound

Optimize & Scale

Cut what's not working, double down on what is, and scale budget behind proof specific to your account.

What I do

Four disciplines through one funnel.

Every discipline below comes back to the same question: why does someone actually decide to buy? I use whichever mix of these gets your business closest to that answer. Most clients end up needing more than one at once.

Strategy & Audits

A clear-eyed look at what's working, what's wasting budget, and the go-to-market plan to fix it.

  • Full-funnel marketing audits
  • Go-to-market planning
  • Competitor & market research

Paid Acquisition

Full-funnel campaigns across Meta, Google, TikTok, Pinterest and LinkedIn, built for ROAS.

  • Campaign setup, targeting & A/B testing
  • Budget scaling with performance guardrails
  • Conversion rate optimization

Email & Lifecycle

Klaviyo and Salesforce flows that turn one-time buyers into repeat customers, plus newsletters people actually open.

  • Automated flows & drip sequences
  • Segmentation & deliverability
  • Copy & design that converts

Social Media Management

Content calendars, organic strategy and community building. I grew my own audience to ~240K without spending a cent on ads, so I know firsthand what that actually takes.

  • Content strategy & production
  • Community management
  • Brand voice & copywriting
