Test which platform reaches your ICP at the lowest cost — all from one place.

The part they didn't cover at YC

Your runway can't afford an agency. Your day can't afford you.

Every founder ends up here. Most of them spend three months and $20k figuring out the options before realizing they needed a different shape of solution.

01

Runway ≠ patience.

Every month without testing paid channels is a month of guessing. Agencies quote $1–7k a month and take 90 days to ramp. You need answers this week — which channel works, which messaging lands, which ICP converts — not next quarter.

02

Your cofounder tried Meta ads last Tuesday.

Three thousand dollars and one week later, they paused everything to get back to shipping. Nobody got a lead. The Ads Manager tab is still open somewhere on their laptop, judging them.

03

You're wearing six hats. Marketing shouldn't be one of them.

You're shipping product, closing deals, hiring, and fundraising. The last thing you need is another tab open — Ads Manager, analytics, attribution spreadsheets. You need a system that runs while you focus on everything else.

What Bytown actually does

Stop guessing which channel works.

Move fast and get answers in weeks. Not next quarter. Describe your product — Bytown drafts campaigns, runs variant tests, and feeds your conversion events back to Google, Meta and LinkedIn. You approve before anything goes live.

01

Live in an hour, not a quarter.

No discovery call. No brand strategy deck. Paste your URL, describe your ICP, and Bytown handles the rest.

02

Fail cheap. Learn fast.

Bytown tests creative variants across channels, kills losers, and scales winners automatically.

03

Slide-ready insights. Always prepared.

Every channel, campaign, and creative tracked in one place — high-level for the board meeting, granular for the standup.

We were burning $6k a month on an agency that couldn't tell us which channel was actually working. Switched to Bytown — same week we had Google Search and LinkedIn running with real tracking. Within a month we knew exactly which platform and messaging our ICP responded to. Cut our agency spend completely and got the insights we actually needed for the board.

Startups using Bytown

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

Hana W.

SaaS

Bytown dashboard, Apr 1 – Jun 24: a SaaS company at 48 leads, $15,591.62 spend, 1.9% conversion rate, $324.83 cost per conversion.

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.

Anneke R.

SaaS

Bytown dashboard, Jan 1 – Aug 13: an enterprise SaaS company at 95 leads, $57,981.50 spend, 1.8% conversion rate, $610.33 cost per conversion.

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

Emeka V.

Marketplace

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

Zara K.

Early-stage startup

Bytown dashboard, Jan 1 – Aug 13: an early-stage startup at 111 leads, $42,978.93 spend, 2.1% conversion rate, $387.20 cost per conversion.

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 optimize against your real conversion signal — not just form fills or vanity leads. You pick the conversion event that matters.

Bytown won't replace a fractional growth marketer — but a fractional hire can work at 10× speed with Bytown. Instead of spending their first 90 days setting up tracking and running manual tests, they plug into Bytown and immediately start testing channels, messaging, and audiences. They focus on strategy and growth problems while Bytown handles the execution across every platform.

Bytown runs your ads on Google Ads, Meta, and LinkedIn, then connects to your analytics and tracking stack — PostHog, Mixpanel, Segment, Stripe, GA4, Customer.io, and Slack for alerts. HubSpot integration is coming soon. Your stack stays where it is. Bytown sits on top and feeds conversion signals back to the ad platforms.

Narrow ICPs are exactly where Bytown shines on LinkedIn. You describe the ICP in a sentence — role, seniority, company size, industry. Bytown builds the audience, drafts the ad copy, and starts testing angles within 24 hours. No targeting spreadsheet required.

If you have no landing page or signup at all, not yet. But if you have a waitlist or a beta signup flow, yes — Bytown can drive signups and early activations while you build the product. Some founders use it to pre-validate the ICP before writing code.

Faster than any other approach. Bytown distributes ads across Google, Meta, and LinkedIn simultaneously — testing channels, audiences, and messaging in parallel instead of one at a time. Most founders see their first qualified leads within days, not months. Within 2–4 weeks you'll have clear data on which channel and ICP converts, so you know exactly where to scale.

Yes — that's the sweet spot. Describe 2–3 ICP hypotheses in plain English. Bytown runs targeted campaigns against each one across multiple platforms simultaneously. Within weeks you'll have real conversion data showing which audience, channel, and messaging resonates — before you commit your full budget. It's the fastest way to validate product-market fit on the paid side.

About 5 minutes to set up, then almost zero ongoing. Bytown handles campaign creation, optimization, and budget allocation automatically. You get a daily WhatsApp summary and approve changes with a reply. No Ads Manager tabs, no weekly agency calls, no spreadsheets. You focus on product, sales, and hiring — Bytown handles the ads.
