You are selling software in the shadow of AWS and Microsoft, against a wave of well-funded local startups bidding on the same category terms and chasing the same technical buyer. We build performance marketing that earns attention from people who ignore fluff.

SaaS · Seattle, WA
No other city packs this many sophisticated software companies into one ecosystem. The Redmond and AWS gravity well pulls in alumni who go on to found Smartsheet, Highspot, Outreach, and a hundred more, all competing for the same category keywords and the same cloud-native, technically literate buyer who can smell a generic demo-request funnel from the first headline. On top of that, the cost of operating here is brutal: Seattle's JumpStart payroll tax bites hard on the high-comp engineering and PMM salaries you are already paying, which means every dollar of acquisition spend has to defend its own margin. Brand spray does not survive in this environment. Efficiency does.
We run performance marketing the way a Seattle SaaS company actually needs it run: as a CAC-and-payback discipline, not a vanity-impressions exercise. Strategy and in-house execution live under one roof, so the team modeling your funnel economics is the same team building the landing pages, writing the technical proof content, and shipping the experiments. When a campaign exposes a friction point in onboarding or pricing, our developers fix it the same day instead of filing a ticket into a queue. You get spend that is accountable to revenue, aimed at buyers who reward substance.
Our Approach
We start with CAC, payback period, and contribution margin, not a media plan. In a market where your payroll costs are inflated and your competitors are well-capitalized, the only durable advantage is acquiring customers more efficiently than they do. Every channel we open has to clear a payback threshold you sign off on first.
Seattle SaaS buyers are engineers, product leaders, and operators who evaluate before they ever book a call. We pair paid acquisition with product-led content, comparison pages, and technical proof that earns trust in a skeptical, cloud-native audience instead of shouting past it.
Our strategists, marketers, and developers sit on one team. When a campaign surfaces a broken signup flow, a slow page, or a pricing objection, we change it now rather than waiting on an outside dev shop. That speed is the difference between a learning loop measured in days and one measured in quarters.
Proof
We do not just run software companies' ads, we have built them: with Updone, our team took a staffing marketplace from concept to a live, revenue-generating product, which is the same strategy-plus-in-house-execution muscle we point at your growth.
Common Questions
What Seattle SaaS teams ask us most.
No. Cosmo is headquartered in Austin and works with SaaS companies across the country, including a strong roster in the Pacific Northwest. We do not need a downtown Seattle address to understand the market you compete in, and you do not pay for one.
Possibly, if your product touches consumer-health-adjacent data. The Act took effect on March 31, 2024 and carries a private right of action through Washington's Consumer Protection Act, which raises the stakes on how you collect and track signals like health-related events. If that describes your product, we build your tracking, consent, and pixel setup to respect it rather than expose you. If it does not apply to you, we keep your stack clean and move on.
Your buyers are national and global, not down the street, and they are technical decision-makers who evaluate before they convert. So we optimize for CAC, payback, and qualified pipeline rather than local foot traffic or raw lead volume, and we invest heavily in proof content that survives the scrutiny of a sophisticated audience.
It collapses the gap between insight and action. The team that models your funnel is the same team that builds the pages, writes the content, and ships the code, so a problem a campaign surfaces gets fixed the same day instead of routed through a separate agency and a separate dev shop.
Yes. We have built and launched products ourselves, so we are comfortable in the messy stretch where positioning, pricing, and the funnel are still moving. We instrument early, run small efficient experiments, and scale spend only once the unit economics hold.
