Every pick recorded. Every result measured.
Saturday Racing publishes AI-generated tips, previews, and long-form race analysis across four distinct editorial brands — with a transparent measurement layer that no other tipping site can match.
UK & Irish racing wagering: £13B annual handle. Consumer racing media & tipping (our TAM): ~£250m. Both segments served by products that read, look, and measure the same way they did before the smartphone existed.
Tipster columns publish picks with zero public track record. Readers can't tell a 30% strike rate from a 12% one.
RPR, TS, OR — decades-old rating systems that even seasoned punters struggle to explain. The reasoning is a black box.
Text-heavy racecards and tabular form guides. No cinematic content. No modern reader would call this an engaging product.
One voice per publication. No differentiated content lanes for different reader modes (tip-hungry vs analytical vs casual).
Every piece of content — from a daily tip to a long-form Papers article — is generated by a structured LLM pipeline, rendered through distinctive editorial brands, and measured against actual race results in a public-facing ledger.
One prompt library. Multiple personas. Structured JSON output rendered through eight+ distinct content formats — from a 30-second Pin capsule to a 5,000-word Race Paper.
Every pick recorded automatically. Every result reconciled. Strike rate + ROI dashboards available live — a level of transparency no other tipping site offers.
Mr Fox (tipster), LLaMa (analytical), Sly Man (bet products), Pinsticker (cinematic previews) — distinct voices allow the same punter to consume in three different modes.
GSAP-driven scroll storytelling, race simulations, multiverse heatmaps. Content formats that don't exist elsewhere in racing.
One data pipeline. One LLM contract. One prompt library. Multiple branded content formats. Measurement loop closes the flywheel.

Y1 growth focus Pick Winner · Bet of the Day · Race Papers. The other formats stay in maintenance mode until revenue mechanics prove out.
Daily AI-generated winner selection per race with confidence, reasoning, shortlist, danger & each-way.
MR FOXRich featured-race preview: 4 archetype picks, comp table for whole field, verdict, dissent from AI Chamber priors.
LLaMa7-scene cinematic race preview. GSAP scroll storytelling. Sound design, countdown, verdict quote, bet card.
PINSTICKERMultiverse simulation with heatmap visualisation. Pace curves, form ribbons, "what-if" scenarios. 7-scene GSAP layer.
LLaMaLong-form analytical letters, one per race in a featured meeting. Post-race grading against actual result.
LLaMaWeekly 3-leg each-way bet with variable EW fractions, per-leg settlement, dead-heat maths, diversity guard.
SLY MANDaily single bet with SP settlement, tipped price P/L, archive with results reconciliation.
SLY MANCommunity layer. Members ("Cubs") make picks, appear on leaderboard, compete with Mr Fox. Retention product.
COMMUNITYThe DEN is Saturday Racing's chat-native concierge — a hybrid deterministic + agentic layer that flattens the whole platform into a single question: what do you want to know? Free Cubs see the signals. Paid Cubs ask LLaMa to investigate why.
Every Cub interaction routes through a £0 detection layer BEFORE any Anthropic call. Horse names, quick actions and canned queries resolve deterministically. Only ambiguous questions reach the LLM.
Every Saturday signal — Bet of the Day · Horses to Watch · AI Pick · Steamers · Yesterday's results · Horse facts. Sees the signals; can't ask why.
30 LLaMa investigations/day. Ask why the signals converge. Compare horses. Interrogate form. Full Honest Record. 98% margin per subscriber.
100/day · Claude Sonnet · long memory · cross-source historical analysis. The upgrade Cubs choose after their first "why does Saturday agree?" moment. 88% margin.
The unit-economics target. Every point above 60% is a Cub interaction that feels AI while spending zero Anthropic tokens. LLM cost stays flat as the product surface compounds monthly.
The strategic direction: The DEN is the compound-interest engine on top of the content moat. Every new signal Saturday ships becomes a free-tier hook, a paid interrogation target, and a daily habit trigger — automatically. One consumer surface. Every product. Zero marginal cost of surfacing.
A production-grade platform engineered to enterprise standards. The metrics below aren't projections — they're what an acquirer, technical partner, or investor can inspect today.
Every tipping site claims accuracy. None publish the maths. Saturday Racing's measurement layer is the first honest track record in racing content — and it compounds with every settled race.
Every AI pick recorded automatically at pick time. Every result reconciled at race-off. Zero manual reporting. Zero cherry-picking.
Every pick stamped with SYSTEM_PROMPT hash (currently v3). Prompt changes become A/B-testable across strike rate + ROI cohorts.
Strike rate + ROI broken down by confidence tier × field size × race type × source × prompt version. Live analytics dashboard.
Confidence labels post-processed by hard sanity rules + signal alignment count. High confidence requires evidence, not opinion.
Never publish a hallucinated pick. Two-tier LLM validation + composite fallback. Every pick is a real horse in a real race.
Roadmap: Reader-facing subset of the dashboard. Rolling strike rate + ROI at advised prices. Trust signal at scale.
Token Economics Prompt caching + structured JSON + deterministic fallback keep per-pick LLM cost under 1p at 100k users — the AI margin story scales without server-cost surprises.
Saturday Racing has been built in public, launched quietly, and grown organically. Registration counts alone under-sell the story — the behavioural signals below are the real proof that the concept resonates.
Preliminary snapshot · GA4 verified before Q1 pitching
Platform Output / week ~250 races analysed · ~300 predictions published · £0 marketing spend · +22% MoM organic traffic · ~38% newsletter open rate
Full AI pipeline · Racing API integration · Results settlement · PickOutcome measurement ledger · Prompt versioning · Analytics dashboards (staff-gated) · Cinematic front-end · Multi-persona editorial system · Cubs community + leaderboard
Months 3–6 post-close: Public "Honest Record" page · First bookmaker affiliate partnership · Subscription tier launch (freemium → premium tips) · Growth marketing pilot · Prompt v4 targeting 30%+ strike rate on High confidence tier (approximately the strike rate of blindly backing the SP favourite)
Every tip page can carry deep-links to major bookmakers with rev-share on new depositing customers. Typical rate: £30–£100 per NDC. Fastest path to first revenue.
Free tier: Mr Fox's Pick + Fox's Wire news. Paid tier (£8–£15/mo): Deep Dives, Papers, Letters, Sly Treble, honest record. Retention-driven by measurement + community.
Racing brands (racecourses, breeding operations, trainers) as named sponsors of specific content lanes — "The William Hill Big Race" style syndication.
PickOutcome dataset + prompt library licensable to bookmakers / racing media as a white-label AI content engine. Rare asset — few racing companies have measurement infrastructure this deep.
Race Papers & LLaMa Letters as licensed content for racing media partners. AI-generated but editorially graded — a rare combination in a syndication market.
Optional white-label bet placement layer with bookmaker integrations. High-friction to build but highest LTV per user. Long-term option, regulatory dependent.
This raise funds Year 1 and Year 2 execution. Year 1 turns readers into competitors; Year 2 turns competitors into subscribers. Long-term, the audience becomes a peer-to-peer liquidity pool — contingent on Y1–Y2 traction and follow-on capital.
Weekly Pick 6 where Cubs select six horses across a Saturday card and compete directly against Mr Fox. Winners take real prizes — cash pool, racecourse hospitality, sponsor gifts. The game becomes the growth engine.
→ 5–10× active user growth · First sponsorship revenue · Passive readers become weekly competitors
Freemium tier converts to premium at £8–15/mo. Multiple bookmaker affiliates live. Public Honest Record ships as a live trust signal. Growth marketing scales. Data-licensing conversations open with racing media + bookmakers.
→ Target £10–30k MRR · 15–30k registered users · positioned for institutional follow-on
Once Y1 audience and Y2 subscription base are proven, a Cub-vs-Cub P2P betting layer is the natural extension. Requires UKGC licence + fresh capital — not funded by this raise. Presented as strategic optionality, not a Y3 commitment.
→ Category redefinition potential · Strategic exit optionality
See top callout for regulatory positioning. The long-term P2P optionality would require UKGC Betting Exchange licensing + dedicated compliance capability + a separate capital round — nothing about this raise depends on it.
Starting from ~1,000 organic users, three catalysts drive step-change acquisition through Y1–Y3. Base case reaches ~50k users by end-Y3; the upside path reaches 100k with strong paid-acquisition efficiency; exceptional execution unlocks 150k+.
7× from launch base · Pick 6 competition + sponsor inbound + first paid acquisition
3× from Y1 · Subscription tier + affiliate BD + growth marketing scale
Retention + paid-acquisition scale · Upside 100k · Exceptional 150k with best-in-class CAC
Base case assumes seed round closes Q1, Pick 6 launches Q3, subscription tier ships Q5, and organic + paid acquisition compound through Y2–Y3. Upside case requires best-in-class paid-acquisition efficiency + strong affiliate-driven conversion. Exceptional case additionally requires viral / editorial breakout moments.
Scales with results.

Incumbents lead on brand authority, distribution, and data depth. We lead on AI-native content architecture and measurement transparency — dimensions the incumbents can't easily replicate.

The engines, in detail.
Deep-dive slides documenting how Bet of the Day, Pick Winner, Horses to Watch and LLaMa Letters work end-to-end — from data ingestion through deterministic scoring, LLM reasoning, guardrails, calibration, and measurement feedback.
Reference material for technical diligence — not required to buy the story.
Eight deterministic steps, one calibrated LLM narrative. The moat is the loop — every bet becomes training data for the next.
Deterministic scoring picks the field. Claude picks the winner. Guardrails guarantee delivery. The fallback is the guarantee — every race gets a pick, every pick gets measured.
The algorithm doesn't pick winners — it finds the five horses today with the strongest evidence across multiple independent signals, and tells the story. Empirically calibrated. Point-in-time correct. Continuously learning.
LLaMa is no longer the decision-maker — she is an editorial layer explaining a deterministic model. Every letter is measurable, testable, and auditable end-to-end. Deterministic scoring engine · AI editorial analysis · evidence-backed racing letters.
