Steve Kaplan, growth marketer and solo builder

Hi, I'm

Steve Kaplan

I spent 15 years moving $50M+ in paid media for other people. Then I built the thing I always wished existed.

Most marketers at this level give you a strategy deck. I give you the system that executes it, and the receipts behind every number.

I built GTMVP: eight AI agents that continuously map competitors, sharpen positioning, score channels, and surface the moves most founders are too close to see. Start with the free Smart Bidding Audit and find out exactly where your ad spend is leaking.

My Operating Principles

Grand Slam Offers

Make offers so good people feel stupid saying no. Every campaign I build starts with an irresistible offer, not just clever ad copy.

3.2x Average ROAS

For every $1 spent on advertising, I average $3.20 back across all campaigns. That's the lifetime number, not a cherry-picked peak.

Leads First

It's hard to be poor with leads banging down your door. I build systems that generate qualified leads on demand.

Builder Not Advisor

Most consultants give you a deck. I build the system that executes it. I write the code. I deploy the infrastructure.

About

Operators do not code. Engineers do not run $50M in live spend. I do both.

15 years in growth marketing. 9 products shipped solo. The rare combination that lets me build the system and run it.

Steve Kaplan

The Short Version

A year ago I was "just" a growth marketer with $50M+ in lifetime ad spend. Good at my job. But watching AI reshape everything.

I didn't hire a dev team. I didn't wait for permission. I started building. Claude Code became my engineering partner. Nine products later, I'm shipping faster than most funded startups.

For 15 years I ran paid media for other people: $50M+ in lifetime spend across Google and Meta, $300K+/month at peak, a 10:1 sustained ROAS at scale. In 2026 I left the in-house seat to go all in on my own products.

Now I build the systems I always wished existed. GTMVP, the paid media OS for founders still logging into the ad account themselves. Attribyte, the attribution platform that measures whether any of it actually worked. The marketing and the engineering, run by the same person.

The backend

Eight specialized agents. Supervised, not autonomous.

GTMVP runs eight agents as the intelligence layer behind every engagement. They audit bidding signals, map competitors, sharpen positioning, and score channels on a weekly cycle. You get the output. You make the calls. The agents do not touch your ad account.

Agent infrastructure is supervised. Every output passes through operator review before it reaches you.

Attribution Platform

Attribyte. MTA, MMM, and incrementality in one platform.

I built Attribyte for marketing leaders at mid-market to enterprise B2B SaaS who need real measurement, not more dashboards. Most teams run three separate tools, get three conflicting answers, and make budget calls by gut. Attribyte puts all three measurement methods in one place so you can stop arguing about what is working.

Multi-Touch Attribution

Deterministic-primary identity resolution. Every touchpoint credited without relying on cookies as the primary path.

Marketing Mix Modeling

Spend-level signal across all channels. Understand incrementality at the portfolio level, not just last-click.

Incrementality Testing

Holdout-based lift measurement built into the platform. Stop guessing whether a channel is actually driving revenue.

Built for

VP Marketing, RevOps, and CMOs who need to answer the question their CFO keeps asking.

Privacy-first architecture. Deterministic identity as the primary path, probabilistic as the fallback. No third-party cookies required to get accurate attribution.

Built by Steve. Not a third-party tool. Owned and operated.

Cookieless-primary. Deterministic identity resolution first.

All three measurement methods. One platform. No stitching.

Shipping Log

Built in Public, Documented in Real Time

Nine products shipped solo. Every commit is logged, every architecture decision is a real one, and the whole thing runs on a stack I can operate alone.

The builds are not demos. They are live products with real users, real errors, and real iteration cycles. That is what the commit history actually shows.

Primary stack:

ReactTypeScriptSupabasePythonClaude Code

How the loop works

  • Claude Code as primary engineering partner
  • Conventional commits, push to main, ship fast
  • Iterate on real usage data, not roadmap assumptions
  • Small focused files, explicit error handling throughout

Profit Loop Audit. 5 days. 5 wins.
Ranked, scoped, dollar-attached.

Not ready to commit to a full GTMVP Rebuild yet? This is the $3,500 flat engagement for founders who want senior operator input before their ad spend warrants a full build. I dig into your stack, find the highest-leverage moves, and hand them to your team in priority order. Money back if I find fewer than 3.

Already running paid media? Start with the free Smart Bidding Audit instead.

How the ranking works

Every win gets two scores. Effort and lift.

Effort is what it costs you to ship: tooling, time, integration risk. Lift is dollars and hours back. We start with the wins that lift profit fastest, with the least effort. Slow lifts go on the 60 or 90-day track. Anything that doesn't clear the bar gets cut.

Patterns I find on most stacks

  • Lead routing that loses 30%+ of inbound to dead-letter status
  • $5K to $30K/month in paid media spent on broken audiences nobody noticed
  • 3 to 5 manual handoffs per deal that an AI workflow eats in an afternoon
  • Attribution gaps that make every channel look like it's working, or none at all
