22 Chrome extensions · Built by a practitioner

Tools for B2B paid media that generic SaaS forgot to build.

A suite of focused Chrome extensions for industrial, manufacturing, and B2B e-commerce paid media managers — built by someone who runs ~$650K/month in actual accounts. No subscriptions. No usage limits. No "read every site you visit" permissions.

The problem

Generic PPC tools were not built for B2B.

Every demo ends the same way: 'we have templates for that, but you're kind of an outlier.' Optmyzr, Adroll, Marin — all built for the average account, not the edge case where the money actually is. Industrial buyers don't search like consumers. Procurement leads don't convert like e-commerce shoppers. Sales cycles run nine months.

B2B contamination kills accounts.

DIY hobbyists and Etsy sellers bid up CPCs in the same auctions as procurement leads at $50M manufacturers. Smart Bidding routes spend toward the cheap clicks. Conversion rates collapse. No vendor builds for this.

Reporting platforms can't see structure.

Naming convention violations, cross-brand cannibalization, SKUs without ad coverage, broken landing pages — none of these surface in any dashboard you'll buy. They show up in a spreadsheet a senior PPC manager builds by hand, every quarter.

Edge-case clients are the entire B2B world.

Multi-brand MCC structures. Custom offline conversion pipelines. 90-day sales cycles. Account names with quote marks in them. The 'outlier' is the median industrial account. The tools were never built for them.

The suite

22 extensions. Each one does one thing.

Every tool is single-purpose. No platforms, no all-in-one dashboards, no upsells. The categories below mirror how the work actually breaks down — pacing math, page taxonomy, audience filtering, feed health, competitive intel, workflow.

Philosophy

Three rules. Every tool follows them.

01

One thing, well.

No platforms. No 'all-in-one' tools. Each extension does one specific job for B2B paid media managers and exits. If a tool starts trying to do two things, it splits into two extensions.

02

Minimum viable permissions.

Most extensions only need 'storage'. None of them ask to read every website you visit. The few that need page access only inject content scripts on specific domains, on user click.

03

Honest output.

Numbers come with units. Unrealistic projections get flagged as unrealistic. AI confidence scores are surfaced, not hidden. When data is partial, the tool says so.

Built for the work, not the demo.

The whole suite is open source on GitHub. Install the built ones in developer mode today. The rest ship on a public roadmap. No email gate, no trial, no "request a demo" funnel.
