Full-funnel programs across paid search, paid social, affiliate, and display. Fast testing on Google, Meta, TikTok, and LinkedIn with clear ROI targets at every stage.

| What you get | In-house hire | Typical agency | Komplex |
|---|---|---|---|
| Who runs your account | One person, one channel | A junior team after the pitch | Founder-led, senior on every account |
| Channels covered | One person | Can be many, but usually siloed | Every channel, or just the one you need |
| Reporting | Depends on the hire | Dashboards and vanity metrics | Attribution-led numbers every week, wins and misses |
| Who owns the ad accounts | You | Often the agency | Always you |
| AI Search (GEO / AEO) | Rarely covered | Sometimes, as an add-on | Built in from day one |
| How you start | Months to hire and ramp up | Possibly weeks of onboarding | An audit and a written plan first |

A digital marketing agency plans and manages the channels that attract online customers to a business. These channels include paid search, paid social, SEO, email, and conversion optimization. At Komplex, we take care of strategy, execution, and reporting, giving you a single accountable team rather than five vendors.
Most Komplex engagements are set up as a monthly retainer tailored to your channels and objectives. Paid media usually carries an added percentage of ad spend, although we’re willing to consider other arrangements if they suit you better. Your ad budgets remain in your own accounts and are sent directly to the platforms, with reporting included. After a brief audit, we define the scope, so you pay only for the work your plan requires.
Typically, a single senior hire handles just one or two channels. By comparison, an agency can provide both strategy and execution across all channels, and it often costs less than one salary. We also work alongside many of our clients’ in-house teams, integrating with the setup they already have.
Yes. There is no charge and no obligation. This is how we demonstrate our approach before you decide whether to engage us. You receive a written plan plus a brief call to review it, and you keep the plan regardless. If, after that, it seems right to collaborate, we define a retainer based on the plan.
Komplex is founder-led. The same person who designs your strategy also manages its execution. On every account, we keep senior-level involvement and support the entire funnel. In addition, we were early adopters of AI search (GEO/AEO), helping your brand appear in the places where buyers now pose questions.
Komplex is based in Austin, Texas, with a presence in New York City and Reykjavik. We work with clients across the US and internationally. We are also fully remote-friendly.
It depends on the channel. After tracking is properly in place, paid campaigns may begin showing change within a few weeks. SEO and GEO/AEO take months to develop, but their effects then build on one another. In your first plan, we define expectations separately for each channel, and from the start we report progress using straightforward numbers.
The essentials are simple: what you offer, where you currently promote it, and what counts as a strong month. If we can view your ad accounts and analytics, we can dig further. Should you require one, we can also put an NDA in place. And if access is not yet available, we can still uncover opportunities using only your site and your market.
