YieldStack's answer
AI integrations supporting the platform’s workflows.
Titans Grip's answer:
Swift 6 with strict concurrency, SwiftUI, SwiftData, iOS 17+. Backend on Supabase (Postgres with RLS). AI video analysis uses CoreML on device combined with cloud inference. AI coach chat powered by frontier LLMs fine-tuned per sport. RevenueCat for subscriptions. TestFlight and Fastlane for CI/CD.
YieldStack's answer
YieldStack combines AI-assisted lender matching with hands-on commercial mortgage brokerage. Borrowers submit once, compare financing options, and work with a team that handles structuring, negotiation, and closing coordination. Borrowers approve lender outreach, with no upfront fees and a broker fee paid only at closing.
Titans Grip's answer:
Titans Grip is a suite of 23 AI coaching apps, one fully dedicated to each sport. Most competitors are either a single generalist fitness app or a boxing-only / BJJ-only product. Titans Grip goes deep on sport-specific rules (IBA, Unified Rules, IBJJF, IPF, IWF, WKF, UWW, IFMA, FIAS and more), sport-specific coach personas, and AI video analysis trained on sport-specific movements. The scoring model rates technique 0 to 100 with frame-by-frame feedback, not just reps counted.
YieldStack's answer
YieldStack helps borrowers evaluate the whole financing offer: rate, leverage, fees, reserves, prepayment terms, and closing requirements. Its platform organizes the process, while its brokerage team helps borrowers find suitable lenders and move the deal forward. One submission gives borrowers a coordinated financing process without an upfront brokerage fee.
Titans Grip's answer:
Because the AI actually understands your sport. A boxing coach on FightCamp does not understand BJJ guard retention. A generalist fitness app like Freeletics does not score a sumo deadlift against IPF depth standards. Titans Grip ships a dedicated app per sport with a dedicated coach persona (Coach Marcus for boxing, Professor Leo for BJJ, Coach Pavel for powerlifting, Coach Ilya for Olympic weightlifting, Kru Somchai for Muay Thai). You get 24/7 chat, video analysis, training log, nutrition, and competition countdown built around your specific sport.
YieldStack's answer
Commercial real estate investors, developers, operators, and mortgage brokers seeking bridge, DSCR, fix-and-flip, construction, multifamily, and permanent financing across the United States.
Titans Grip's answer:
Serious amateur through advanced athletes in combat sports (boxing, MMA, BJJ, Muay Thai, judo, wrestling, karate, taekwondo, krav maga, kickboxing, kung fu, sambo, aikido), strength sports (powerlifting, strongman, Olympic weightlifting), and fitness disciplines (CrossFit, calisthenics, bouldering, bodybuilding, Pilates). Ages 16 to 45, training 3+ times per week, often prepping for competitions or belt tests. Users who want real coaching feedback but cannot afford a private coach.
YieldStack's answer
Rommin Adl and Daniel Chesney founded YieldStack to simplify commercial real estate financing. The platform brings deal preparation, lender matching, offer comparison, and closing coordination into one workflow, combining AI-assisted analysis with human brokerage expertise.
Titans Grip's answer:
Titans Grip started with a simple observation: if you train boxing, you need a boxing app. If you train BJJ, you need a BJJ app. Generalist fitness apps do not cut it for technique-heavy sports. We built one app per sport, each with AI trained on the sport rules, terminology, and scoring criteria. Part of Doved Studio, an indie studio focused on vertical AI tools for niche audiences.
