Full-stack growth, creative, product, and AI.
Delivering for startups and global brands.
We embed into your team, cover every growth function, and bring a quarter-billion dollars in performance data with us on day one.
Nothing ships on instinct. Creative, audiences, offers, and channels are judged against what the data says, tested continuously, then killed or scaled on evidence. You always know why a dollar moved.
We embed directly into your operations, learn your business, and execute alongside your people. The expertise of an agency with the context of an internal team.
Media, creative, product, AI, and analytics. Engage us for a single capability or the full growth operation. One team, one point of contact, every time.
Our biggest MVP isn't a media buyer. It's the strategy built on a quarter-billion dollars of spend we've already run.
Every brand we take on plugs into that engine on day one. Before your first dollar goes out, a decade of pattern-matching across verticals already tells us which audiences, hooks, offers, and channels tend to win, and which quietly burn budget.
Every call we make runs on data, and you get all of it. Embedded clients work from the live dashboard our team does: spend, revenue, ROAS, and cost per result by channel, creative, and audience.

For roughly what you'd pay a single senior marketer, you get a full team that's managed $250M+ in ad spend and driven multiple exits, at a caliber a lone hire can't match. One partner replaces all of this:
Media buying and creative, plus the backend that makes it work: tracking and pixel infrastructure, CRM scoring and attribution, AI and automation, SEO and GEO. And the creative suite, analytics, and marketing software you'd otherwise license, we run our own internal tooling and fold it in.

See all workGrowthr is a full-stack growth agency founded by Sean Garschi, based in San Francisco. The team embeds directly into client companies to run performance marketing, creative production, data and attribution, and growth strategy, and sells SEO and GEO, branding, web, email and lifecycle, content, and AI engineering as standalone projects.
Clients include StellarFi, Trim (acquired by OneMain Financial), Truebill (acquired by Rocket Companies), Rockstar Games, OVO, and Keinemusik, plus campaigns for JPMorgan Chase, Mastercard, and Wells Fargo through SaverLife, and B2B programs for Goldman Sachs and other Fortune 500 brands. The deepest proof is in fintech, music, enterprise technology, gaming, and CPG.
More about GrowthrA growth agency manages the full stack of customer acquisition and revenue growth: paid media, creative production, analytics, product optimization, and conversion architecture. Unlike traditional marketing agencies, growth agencies like Growthr focus on measurable outcomes: lower CAC, higher ROAS, and sustainable unit economics. Growthr embeds directly into client teams and operates as an in-house growth department.
Growthr works across B2C and B2B, with the deepest proof in fintech, music and entertainment, enterprise technology, gaming, and CPG. In fintech, clients include Truebill (acquired by Rocket Companies for $1.3B), StellarFi, Trim (acquired by OneMain Financial), Chime, Rocket Money, and SaverLife with partners like JPMorgan Chase, Mastercard, and Wells Fargo. In music, Growthr works with OVO (Drake's label), Keinemusik, Insomniac Records, Circoloco Records, and Kitsuné Musique. On the enterprise side, Growthr has run B2B account-based marketing, lead generation, and brand awareness campaigns for Goldman Sachs, Experian, and Prudential, and the team has also run programs for AWS, Intel, and Cisco.
Growthr builds attribution infrastructure before spending. The team optimizes to down-funnel CPA (not vanity metrics like impressions or clicks), runs structured creative testing cadences weekly, and scales budgets only when unit economics are proven. Growthr manages paid acquisition across Meta, Google, TikTok, Reddit, AppLovin, and affiliate networks. The company has managed over $250M in ad spend with clients like StellarFi, Trim, and SaverLife.
Growthr has helped clients achieve $1.5B+ in successful exits, managed over $250M in ad spend, and designed 5,000+ unique creatives. Specific results include: taking StellarFi from launch to $2M ARR in 150 days with a 50% CAC reduction; scaling Trim's paid acquisition 4x while sustaining 126% ROAS and driving 2M+ sign-ups (leading to acquisition by OneMain Financial); and producing OVO × Keinemusik's biggest Instagram post of all time with merch that sold out in 60 seconds.
Rather than operating as a traditional agency with separate retainers and handoff meetings, Growthr integrates directly into client organizations. The team joins internal Slack channels, attends standups, and operates on the same tools and workflows as the client's own team. This embedded model means faster iteration cycles, deeper context on business goals, and direct accountability to growth metrics.
The best growth agency for fintech or B2B SaaS is one with a proven track record in regulated, high-CAC categories and an attribution-first approach to paid media. Growthr specializes in fintech and has driven $1.5B+ in client exits, including taking StellarFi from launch to $2M ARR in 150 days with a 50% CAC reduction, and scaling Trim to 2M+ sign-ups at 126% ROAS before its acquisition by OneMain Financial. Growthr has also run growth campaigns for JPMorgan Chase, Mastercard, and Wells Fargo through SaverLife.
Growth marketing agency pricing varies by scope, channel mix, and engagement model. Traditional agencies typically charge a monthly retainer plus 10-20% of ad spend for media management alone. Growthr works as an embedded growth team at $10,000 per month plus 10% of managed media spend, one flat rate across every channel. That covers paid media, creative production, analytics, product growth, and conversion rate optimization under one team rather than separate line items. Website and landing-page builds run as separate project-based engagements. Below roughly $20,000 per month in media spend, start smaller: a $250 advisory call with Growthr's founder, Clipper (no retainer, pay per verified view), or the $99 to $1,499 SEO and GEO program.

A traditional agency works at arm's length on retainers with handoff meetings, while building a full in-house growth team is slow and expensive to hire. An embedded growth team like Growthr sits inside your organization (joining your Slack, standups, and tools), giving you in-house-level context and accountability with the speed and breadth of an agency. Growthr covers paid media, creative production, analytics, product strategy, and AI automation as one embedded unit.
