About
Built by a B2B marketer who kept rebuilding the same spreadsheet every time a campaign needed a blended ROAS check. Most published benchmarks were built on ecommerce data and didn't hold up for B2B, so MarketerKit was built to fix both problems at once.
Most free ROAS calculators handle one channel and give you a single number. MarketerKit lets you add every channel in a campaign, see blended and per-channel ROAS, and benchmarks each one against ranges built specifically for B2B — not generic ecommerce data borrowed from elsewhere. The paid report adds the layer most people actually need next: which channel is working, which isn't, and where to shift budget.
B2B marketers running paid campaigns across multiple channels — in-house marketers, agencies managing client budgets, and paid media managers who need a quick, credible answer on campaign performance.
