Seattle founders raise into a market that defaults to enterprise B2B and AI, then burn runway competing for attention against Amazon and Microsoft budgets. We build paid acquisition that earns its keep before the next round.

Seattle is a cloud and AI town shaped by Amazon, Microsoft, AWS, and institutions like the Allen Institute for AI and the UW Allen School. That gives founders deep technical talent, but it also sets the bar: investors here expect B2B SaaS or AI defaults, engineering salaries run high, and a lot of growth-stage capital still routes through Bay Area firms. Runway is short and expensive, so a marketing spend that cannot show CAC payback inside a quarter is a real threat, not a line item. Meanwhile your acquisition channels are competing for the same clicks and the same engineers as companies with effectively unlimited budgets.
We treat your spend like the runway it is. Strategy and execution sit under one roof, so we build positioning that reads as defensible to a Seattle B2B and AI investor, then ship the campaigns, landing pages, and tracking that prove unit economics fast. Our dev team ships same-day, which means when a channel works we scale it that week instead of waiting on a queue. You get acquisition that you can put in front of your board with a clear payback number, not a vanity dashboard.
Our Approach
We sharpen your message so it lands with the B2B and AI-literate buyers and backers this market is built around. Generic 'we use AI' copy is table stakes here, so we make the actual wedge legible before a dollar goes to paid.
Every channel we open is tied to a CAC and payback target you can defend to your board. We kill what does not pay and pour budget into what does, because Seattle runway is too expensive to fund experiments that never close the loop.
Strategy, creative, media, and development sit on one team. When a test wins we ship the landing page, tracking, and scaled campaign the same day, so momentum compounds between rounds instead of stalling in a vendor backlog.
Proof
We launched Acre AI from zero to market, taking an AI startup from no presence to a live, acquiring product, the same standing-start challenge most Seattle founders face.
Common Questions
What Seattle Startups teams ask us most.
No. Cosmo is headquartered in Austin and works with startups across the country, including a roster of Seattle founders. You get a senior team that understands this market without paying for local agency overhead.
Seattle's capital and talent orbit Amazon, Microsoft, and the region's cloud and AI institutions, so investor expectations skew B2B and AI and engineering costs run high. That compresses runway and forces paid acquisition to prove CAC payback faster than it would in a less concentrated market.
Often the better first move is a tight wedge and a few controlled channels to prove demand and unit economics, exactly the kind of signal Seattle investors want before a round. We scope to your stage rather than burning runway on premature scale.
Strategy, creative, media, and development are in-house on one team, so our dev team ships landing pages and tracking same-day. When a channel proves out, we scale it within the same week.
We report against CAC and payback, not impressions. You get a clear read on what each channel costs to acquire a customer and how quickly that spend pays back, in language a Seattle board will accept.
