Startups · Los Angeles, CA
Los Angeles is one of the most expensive and crowded customer-acquisition markets in the country. Silicon Beach is packed with venture-backed startups, DTC brands, and AI companies all bidding against each other for the same eyeballs, which pushes CPMs and CACs higher than founders budget for. Add California privacy rules like CCPA and CPRA that erode the tracking signal your campaigns depend on, plus a board that wants a clear payback period before the next raise, and the generic agency playbook quietly torches months of runway on traffic that never converts to retained users or revenue.
Cosmo runs startup performance marketing built for that exact pressure. We optimize toward the metrics your investors actually grade you on, like qualified pipeline, activated users, and CAC payback, not vanity clicks, and we structure tracking to stay compliant with California privacy law while still feeding the platforms enough signal to learn. Strategy and execution sit under one roof, so when an offer misses or a channel stalls, our in-house dev team ships the landing page or funnel change the same day instead of letting a crowded LA auction drain your budget for a week.
Our Approach
We start by pressure-testing where your earliest, cheapest demand actually lives, the specific Los Angeles audience or use case that converts before the market gets expensive. That wedge tells us which channels to run and which single metric each campaign has to move, so we are validating fit, not buying awareness you cannot afford yet.
Our team sets up conversion tracking that respects CCPA and CPRA while still giving the platforms signal to optimize, then our in-house developers build and ship the landing pages and onboarding flows. You get a full path from ad to activated user, instrumented so you can see real CAC, not a blended number that hides the truth.
We watch qualified pipeline, activation, and cost per acquisition daily, kill what underperforms, and ship page and campaign changes same-day. As the winning channels prove out a payback period your board will fund, we scale spend deliberately so your next raise is backed by traction, not promises.
Proof
When Acre AI needed to go from zero to market, Cosmo launched the AI startup end to end, building the digital experience and a capital-efficient go-to-market engine that turned a technically complex product into validated demand and an early-adopter pipeline.
Common Questions
What Los Angeles Startups teams ask us most.
Yes. Cosmo is headquartered in Austin and serves startups across Los Angeles and the rest of the country. Performance marketing is run remotely by design, and our clients care that strategy and in-house execution sit under one roof, not that we share a zip code. You get the same daily optimization and same-day dev turnaround whether you are in Santa Monica, Venice, or downtown LA.
We structure conversion tracking to stay compliant with California privacy law while still feeding the ad platforms enough signal to optimize. Privacy compliance and performance are not a trade-off when the setup is done right from the start, which matters more in California than almost anywhere else.
Yes, but it has to be run for capital efficiency, not scale. We focus early spend on finding your cheapest, highest-intent demand and proving a CAC payback period your board will fund, the same approach we used to launch Acre AI from zero to market. We validate fit before we ask you to pour budget into a crowded LA auction.
Qualified pipeline, activated users, and cost per acquisition with a defensible payback period, the numbers that move your next raise. We do not measure success by clicks or impressions, because those do not survive a board meeting or a tight Los Angeles ad market.
Strategy and execution live under one roof, including an in-house dev team that ships landing page and funnel changes the same day. In a market as competitive as Silicon Beach, that speed is the difference between catching a working channel and watching a slow vendor leak your runway.
