Antenna designs and builds the digital side of a business: the site people find you on, the brand that makes you recognizable, and the apps and AI tools that give you time back. We work closely with you, move quickly, and hand you something you own.
Every card opens the live thing. The full list, including the software we build for our own ventures, is on the work page.
A site for a respected Westside Realtor who trained as a designer: identity quizzes, design-aware calculators, and a journal in her own voice.

A site for infrastructure that brings real-world assets into regulated digital markets, written for the lawyers and capital allocators who decide in seconds.

The sites, apps and AI tools behind Now City, the real estate company our founder runs: software a team works in every day.

Be found, look the part, and spend less time on the work around the work.
Start with one piece or put them together. Each one is built to work with the others, and to keep working after we hand it over.
Custom websites that load instantly, are easy to find in Google and AI search, and cost almost nothing to run.
Name, voice, logo and a brand kit your team and your AI tools can both use, so everything you put out looks like you.
Web apps for when a site isn't enough: client portals, internal tools, member areas, dashboards, booking systems.
Assistants and agents built into how you already work: drafting, intake, follow-ups, research, reporting.
What to build first, who to talk to, and how to tell whether it's working, for a launch or a new market.
Founder-level guidance from someone who has run small businesses since 2010, for when the question is bigger than the next build.
Hands-on workshops for your team, built around your actual work, with materials they keep.
One-to-one help deciding where AI fits in your business, then working alongside you on the piece that matters most.
Antenna's founder also runs Now City, a real estate development company, and designed and built its sites and software. That includes the Upside Explorer, a live deal model a whole team works on together, and Project Hubs, a private page per engagement that the client can open.
Now City is our own venture, not an outside client. We show it because it's the clearest picture of what we can build for you.
One private page per engagement: milestones, a task board, updates and documents, shared with the client through a private link.

Within a week you know what we'd build together, what it would cost, and how long it would take.
Drafts in days, real options instead of one mockup, and decisions made as we go.
You own the code, the content and the domain. We can keep running it, or teach your team to.
Work that used to need an agency team and an agency budget is now within reach of a small business. AI carries the production load: drafts in your voice, variations, configuration, speed. We keep the strategy, the judgment, the editorial standard and the relationship with you.
No monthly platform fee, no plugins to update, no login to get hacked. Sites we build run for years on almost nothing, and if you ever leave, you take everything with you.
Antenna's marketing platform for agents and boutique brokerages: the same craft as our other work, shaped around how a real estate practice actually wins business.
Antenna is led by Erik Gillberg in Los Angeles. Since 2010, Erik and a small distributed team have helped people and small businesses succeed with custom websites, brand identity, marketing strategy and coaching, and now with apps and AI tools. Every engagement is led personally.
Erik also founded Now City, a real estate development company, so Antenna brings an owner's view to the work. We bring specialists in when the work calls for them.
We value curiosity, creativity and courage. In business and in life.
We'll text or email you back to set up a 15-minute conversation: we'll listen to your business, look at a live example, and talk through what we could build together.
