Our marketing team is me. Bytown gives me leverage to not feel like I am underwater because it takes execution off my plate.

We couldn’t afford a marketing hire. Had ads running by the end of the afternoon.

Elif G.

Early-stage startup

Our enterprise deals take 6-9 months to close. Bytown is great for ABM style campaigns, specific to our ICPs. I stopped panicking about week-three numbers and started watching pipeline instead.

Two-sided marketplace, two sets of campaigns. It juggles both better than I did.

We pivoted twice in a year. Rebuilding campaigns each time would’ve killed us. Bytown did it for me - a huge time saver.

I’m a one-man band. This is the closest thing I’ve got to a marketing department, and it costs less than a contractor.

Questions founders actually ask

Yes. Bytown tracks from click to trial to activated account and feeds those events back to Google and LinkedIn, so the platforms optimise against your real conversion signal instead of form fills. You choose which event counts — the one that predicts revenue, not the one that is easiest to fire.

Narrow is the easy case, especially on LinkedIn. Describe the ICP in a sentence — role, seniority, company size, industry — and Bytown builds the audience, drafts copy against it, and starts testing angles within 24 hours. No targeting spreadsheet and no media planner required.

If there is nowhere for a click to land, not yet. But a waitlist or beta signup page is enough — Bytown can drive signups and early activations while you build, and plenty of founders use it to pre-validate the ICP before they write more code.

Yes, and it is the sweet spot. Describe two or three ICP hypotheses in plain English; Bytown runs campaigns against each across platforms at once. Within weeks you have real conversion data showing which audience and message lands — before you commit the full budget.

Faster than testing one channel at a time. Bytown runs Google, Meta and LinkedIn in parallel, so channels, audiences and messaging get tested together. First qualified leads usually arrive within days, and by week two to four you know which channel and ICP converts.
