Fantenna turns your engagement objective into a shippable format in hours not weeks.

Fandom is the most powerful force in culture. The question is no longer how to build for fans, it's what to build. Fantenna helps brands tap in, nurture it, create it, and convert it into first‑party relationships. Backed by a decade of methodology, five specialist agents, behaviour from 300 million fans per year, and the Future Fan Panel, real people in the cities where culture emerges.

The team

Five specialist agents. One staff meeting.

Each agent has a specific job, a specific voice, and a strong opinion. They debate every recommendation with named axes of disagreement, so you read what survived, what was killed, and what was reshaped, not a summary that hides the working.

Future Fan Panel

Real fans, in the cities where culture and trends are born.

Behind every Fantenna recommendation is a panel of real fans, recruited, paid and looked after directly, in the markets where fandom is shifting fastest. The agents read panel responses alongside your first-party data, so what you build is grounded in actual human language, not just signals. The panel is scaling: London is live, expanded coverage across UK, North America, France, Germany and the rest of Europe is rolling through 2026.

Fantenna · the founding principle
From brief to ship

Commission your fan engagement plan. From brief to ship.

Fantenna doesn't stop at recommendations. The commission flows from your brief through the agent debate to a deliverable creative-and-technology plan, ready to ship. Strategy, format design, surface choice, sponsor pack and the technical spec arrive together, not in three separate procurement cycles.

01

Your brief, interrogated

Decoded brief, agent debate, fan-funnel projection. Defensible to your board.

Decoded brief
Your commitment, interrogated against fan voice. Hidden assumptions surfaced, comfortable answers flagged, hypotheses tagged for testing.
Agent debate transcript
Five specialists arguing every finding with evidence and counter-evidence. Named axes of disagreement. Decisions logged. You read what survived, what was killed, what was reshaped.
Fan-funnel projection
Attention sources, 360-engagement, conversion outcomes, revenue uplift. Low / expected / high per dial. The math shown.
02

The build, pre-wrapped

Recommendations come with the artefacts you ship. Web, mobile, CTV, SDK, sponsor pack, named destination.

Web · App · CTV
Production-grade implementations on the surfaces you own. Native iOS / Android, web overlays, FAST channel companions, second-screen experiences.
SDK / Raw code
Embed Fantenna formats directly. JavaScript SDK shipped today; native SDKs on the roadmap. Your engineering team owns the surface.
Live commerce flow
Format-driven shoppable moments: vote and buy, predict and unlock, identity card with embedded merch. For broadcasters and sponsor activations alike.
Wallet / messaging / DOOH
Apple Wallet + Google Wallet pass templates, WhatsApp Business + iMessage Rich + RCS templates, in-venue QR-pull and lobby sequences.

Build, hosted and shipped on our delivery platform: a fan engagement infrastructure that powers more than 240 live formats and processes hundreds of millions of fan interactions a year.

The creators on our roster

Tap into a roster of vetted creators.

When AI templates are not enough, send the brief to a vetted creator on the Fantenna roster. Real humans, real voices, on-brand. Recruited and managed for cultural fit in their market, not generic influencer pools. Across the cohort: tactics writers, highlights editors, long-form video, match-day reactives, and culture-led storytellers.

World-class engagement formats

Every surface. Every format. Phone-first. Every generation reached.

Fans live across web, app, messaging, social, the second screen, the venue and the operating system itself. Fantenna closes the loop on every one: listening for signal, shipping the right format, reading the response. Built phone-first for the audiences raised on phones, scaled to reach every generation that watches sport.

Formats · the unit of fan engagement

A format is one engagement primitive: a survey, a vote, a predict-and-react, a drop. Fantenna ships a format to a surface for a moment. Every shipped format teaches the agents what works for which fans, where.

FORMAT 01

Predict and React

Live, in-the-moment prediction games tied to a beat in the broadcast. Highest dwell-time format we run.

App · CTV · Web
FORMAT 02

Pick and Win

Fan voting on outcomes, line-ups, MVPs and brackets. Moves the needle on identity and status.

Messaging · Social · Web
FORMAT 03

Daily Poll

Question-of-the-day to a Future Fan Panel cohort. Answers feed back into the morning brief.

Messaging · App
FORMAT 04

Fan Card

Shareable fan profile cards: what kind of fan you are, who you'd recommend. Built for social.

Social · OS-level · App
FORMAT 05

Team Fan App

Second-screen experience that tracks the live event, with stats, votes and prompts for the moment.

App · CTV · Web
FORMAT 06

Drop and Unlock

Time-bound digital drops: collectibles, reveals, unlockables, gated by participation or location.

App · In-venue · OS-level
Unique context

Built on a decade of fan engagement, not hype.

Fantenna sits on top of a fan engagement infrastructure that has been live for more than ten years. The agents are tuned on telemetry from hundreds of millions of live-format sessions, hundreds of named customer deployments, and a moving fan-voice corpus from real cohorts. The training data is the moat; the agents are the interface.

240+ live formats in production
51M+ votes in a single 11-day campaign
Hundreds of thousands of marketing-consented sign-ups via one format
23 cities in the active fan voice panel

Customers include the world's top-flight rights holders, broadcasters and fan-led brands. Premier League. Bundesliga. NBA. Real Madrid. FIFA+. Formula E. WSL. Sky Sports. Peacock. EA SPORTS. SuperSport. Stats Perform. Fanatics. The construct library and case-study library inside Fantenna are anchored against named, deployed customer work, not theoretical patterns.

The loop

Measure. Learn. Iterate.

Every shipped format feeds telemetry back into the agents, sharpening the next recommendation. Iteration is the design target, not the exception. v2, v3, v4 of every format is the standard. Decks on a shelf are the alternative.

STEP 01
Ship.
The commission delivers a working format on your chosen surfaces. Web, mobile, CTV, in-venue, messaging, OS-level. Live in the wild, with measurement instrumented from the first interaction.
STEP 02
Measure.
Closed-loop SDK in your apps captures every fan interaction. Engagement curves, conversion rates, share velocity, sponsor pack lift. The agents read your live telemetry, not screenshots from a quarterly review.
STEP 03
Learn.
Format Doctor reads the telemetry and tells you which dials are off, which mechanics are saturating, which cohorts are responding. Self-critique stage audits whether the recommendations held against the live numbers.
STEP 04
Iterate.
The next commission inherits everything you have learned. v2 ships, v3 ships, v4 ships. Engagement compounds. Fan engagement stops being a quarterly project and starts being a continuous practice.
Enterprise

Add your own organisational context. Sharper output, grounded in your reality.

At Enterprise tier, Fantenna learns from what you already know. Your CRM. Your past campaigns. Your apps and sites. Your tone of voice. Your sponsor deals. The agents stop guessing and start citing your reality. The output is something you can actually ship.

STACK
your tech stack and integrations recognised
DATA

VOICE

BENCHMARKS

Format Doctor ✚

"Your prior bracket campaign converted at 22% on iOS but only 9% on web. Same audience, same format. The drop is the third-step opt-in. Run iOS-first, web as the share surface."

Cultural Antenna ◐

"Your Brazilian cohort is asking the same questions your German cohort was asking eighteen months ago. The local-language commentary feature you shipped in DE in 2024 maps directly. Six-week window before competitors notice."

[Source: customer-context, file: cohorts/by-market.md]

Opportunity Agent ▲

"60% of this lands in your existing stack: your iOS app handles the vote flow, your CRM owns the cohort, your Tuesday email cadence already runs. Net new build is the second-screen variant for CTV. 9 days end-to-end."

Who is it for

I'm a ___ how do I use Fantenna?

Fantenna gets adopted across departments because budgets pool naturally around fan engagement. Here is how each role uses it.

EX
For Executives
Bet your year on the right calendar moment.
Cultural-moment cycles compress. Decision cadence has not. Fantenna decodes any fan engagement bet in hours, gives you a defensible answer to take to the board, and tells you what to ship before the moment passes.
PP
For Product People
Brief in. Build artefacts out. One commission.
Web, mobile, CTV, SDK, messaging, in-venue, OS-level. The recommendation arrives pre-wrapped with the technical spec, the surface choice, the integration plan, the sponsor pack. One commission, not three procurement cycles.
PA
For Partner Activation
Activation inventory by design.
Every recommended format ships with a sponsor pack: the activation moment, the lockup spec, the inventory model, the measurement plan. Sponsors get presented with named opportunities, not generic engagement promises.
SS
For Sponsorship Sales Teams
Engagement-as-evidence for renewals.
Closed-loop SDK turns engagement into live, attributable data. Renewal conversations stop being about pitched-quarter screenshots and start being about continuous, measurable fan engagement against the partner's specific KPIs.
ST
For Strategists
Read the agent debate, not a polished deck.
Five specialists arguing every recommendation with named axes of disagreement. Verdicts mark what survived, what was killed, what was reshaped. The working is shown so you can disagree with it intelligently.
PR
For Procurement
Pooled budget. No seat caps. Built for cross-departmental adoption.
One organisation contract. Unlimited internal logins. Shared scenario library across departments. Pooled token budget so the more your teams use it, the more the value compounds. Standard data-processor terms, contract-end deletion built in.
Three tiers · one engine

Try it on application. Deploy it operationally. Embed it across your organisation.

Fantenna runs against a canonical knowledge corpus by default. The unlock is loading your in-house context: brand guidelines, prior campaigns, surface telemetry, CRM cohorts, broadcast deal terms. Pro and Enterprise tiers turn directional output into operationally accurate output. Discounted access available for qualifying charities, public-interest research and educational institutions.

Free Trial 7 days, by application

A real Fantenna run, with no in-house context. Directional output, valuable as a sample of what the product does. Issued to qualified rights holders, broadcasters and brands, not self-service.

  • Limited scenario runs against your brief
  • Canonical Fantenna knowledge corpus
  • Public Future Fan Panel (12 cities)
  • Markdown transcript of every stage
  • Self-critique that tells you what you cannot trust yet
Enterprise Cross-departmental adoption

Operationally embedded across your organisation. One contract, unlimited internal logins, pooled budget, shared scenario library. Your own panel cell, your SDK in your apps, your named destination. Fantenna becomes the closed loop between your fan signal and your next deployment.

  • Everything in Pro, plus:
  • Unlimited internal logins, no seat caps, pooled budget across departments
  • Dedicated Future Fan Panel cell in your markets
  • Fantenna SDK in your apps (closed-loop measurement)
  • Generative output suite scoped to your brand assets
  • Named destination productisation per the Match Centre pattern
  • Quarterly customer-context refresh by the CSM team
  • Direct integration with your Snowflake / Databricks / CDP

Pro tier ingests your context once at onboarding. Enterprise refreshes quarterly + integrates real-time. The technical pipeline (`fantenna run --tier pro --customer-context-dir <path>`) is the same; the services layer + commitment cadence is what changes.

Questions, properly answered

Can we answer that question?

Is this just an LLM wrapper?

No. The agents are tuned on a decade of fan engagement work, telemetry from millions of live-format sessions, panel waves, and hundreds of shipped briefs. The model is the cheap part. The training data and the construct library are the moat.

How do you stop the AI hallucinating recommendations?

Three architectural commitments. First, a grading dial sets the latitude per run: STRICT mode constrains agents to canonical constructs and case studies only; REFERENCED mode allows novel proposals provided each carries an external citation; ARTISTIC LICENSE mode permits exploratory ideas with internal justification (used for early concept work, never for shippable plans). Second, the five-specialist debate forces named axes of disagreement and at least one killed or reshaped hypothesis per run. Third, the self-critique stage audits phantom-math and agreement-too-easily before the run closes.

Do I have to use your delivery platform to ship?

No. Briefs are portable. Send them to our delivery platform, your in-house team, your roster of creators, or post them externally. We charge for the agents and the strategy layer, not the build. Most customers use the delivery platform for the heavy infrastructure and creators for the on-brand content layer.

What about my fans' data?

You bring the sources, you own the data. Fantenna processes fan voices in your tenant, never trains on it, and gives you a one-click export of every quote, decision, and brief. Contract-end deletion is built in.

How fast can I get up and running?

The Free Trial runs the same day, against the canonical corpus. Pro tier customer-context ingestion takes weeks (not months). Enterprise customer-success engagements typically deliver the first operationally-accurate run within a quarter.

Can multiple departments use one Enterprise contract?

Yes. The Enterprise tier is built for cross-departmental adoption. One organisation contract, unlimited internal logins, pooled budget, shared scenario library across departments. Per-run privacy flags let teams keep work private to a department or share organisation-wide. The more teams that use it, the more the data compounds.
