HYBRD

What do they actually do

HYBRD is an iPhone app for people who both lift and do endurance training. It pulls your workout data from services and devices you already use (Apple Health, Garmin, WHOOP, Strava, TrainingPeaks, Peloton, Concept2, Zwift, Fitbit, etc.), generates a goal‑based plan that balances strength and cardio, and tracks your sessions automatically. You can log lifts by typing, voice, or snapping a photo of a whiteboard, and the app pushes scheduled workouts to compatible watches. After each session you get analytics, including a single training score that separates strength and cardio, plus race‑time predictions for run plans (HYBRD site; App Store).

The product is live on iOS with a 7‑day free trial; membership is listed at $99/year. HYBRD emphasizes plans that adapt to your data and is adding coached, sport‑specific programs for hybrid use cases like triathlon and Hyrox. Android is not available yet but is explicitly on the roadmap (HYBRD site/FAQ; App Store).

Who are their target customer(s)

• Hybrid endurance athletes who also lift (e.g., triathletes, ultra runners): Managing long cardio blocks alongside strength work across multiple apps makes pacing, recovery, and tradeoffs hard to see. They want race‑ready plans that reflect their real training history and fatigue (HYBRD; App Store).
• CrossFit/Hyrox and functional fitness competitors: They need to progress both high‑intensity conditioning and maximal strength, and logging complex lifts is tedious. They want programs and analytics tailored to hybrid events like Hyrox (YC profile; HYBRD).
• Recreational racers seeking personalized race prep: Generic templates don’t account for their past workouts, so pace predictions and when to emphasize strength vs. endurance aren’t trustworthy. They need plans that adapt automatically (App Store).
• Busy adults training multiple modalities: Manual set entry and switching between apps leads to missed logs and incomplete data. They want low‑friction logging and a single place to see everything (HYBRD features/FAQ).
• Coaches or serious amateurs managing structured plans: They need consistent, comparable metrics across athletes and an easier way to publish coach‑led programs that adapt to data (YC profile; App Store).

How would they acquire their first 10, 50, and 100 customers

• First 10: Use founders’ networks (ex‑WHOOP colleagues, YC peers) to recruit paid beta users with discounted annual plans and white‑glove onboarding; capture concrete case studies from connected devices and races for credibility (YC profile; HYBRD).
• First 50: Partner with local tri clubs, Hyrox/CrossFit gyms, and independent coaches with free coach accounts and invite codes; demo at group workouts and seed niche communities (Strava clubs, Reddit, FB groups) with data‑backed posts (HYBRD integrations).
• First 100: Spin up an ambassador cohort (coaches + community athletes) with rev share, sponsor small local races/Hyrox events for on‑site trials, and run tight paid ads to iOS trial signups; reinforce with ASO, in‑app referrals, and instant wearable sync to show value in week one (App Store).

What is the rough total addressable market

Top-down context:

Strava reports over 180M users globally, with 54% now tracking multiple activities; if 2–3% of this multi‑sport cohort paid ~$99/year for hybrid coaching, that implies ~$190M–$290M annual spend potential for a hybrid‑training app category (Strava 2025 report/press; Strava 2024–25 trends).

Bottom-up calculation:

Across adjacent hybrid segments: CrossFit has an estimated 2–5M global participants (midpoint ~3.5M), Hyrox reported 90k athletes in its 22/23 season with rapid growth, and USA Triathlon counted ~302k active U.S. members in 2024. If ~5% of these combined athletes (~200k) buy a $99/year hybrid plan, that’s roughly ~$20M in annual revenue, with upside as Hyrox and tri participation rebound and grow (CrossFit; HYROX history; USA Triathlon 2024 Impact).

Assumptions:

• Price stays ~$99/year and comparable to other training apps.
• Overlap between CrossFit, Hyrox, and triathlon is partially de‑duplicated via a conservative 5% purchaser rate.
• Multi‑sport Strava users are a reasonable proxy for the broader hybrid‑training addressable audience.

Who are some of their notable competitors

• TrainingPeaks: Endurance‑first planning and analysis with a large plan marketplace and coach tooling; overlaps on structured plans and device sync but is focused on coach workflows and endurance periodization, not auto‑balancing strength+cardio (Coaches, Training Plans).
• WHOOP: Wearable + subscription that quantifies daily strain and recovery and gives day‑to‑day guidance; overlaps on hybrid load analytics, but it’s hardware‑centric and not a personalized hybrid plan generator (Strain explainer, Support).
• Peloton: Content and hardware ecosystem with large on‑demand strength and cardio libraries; competes for integrated programming but is content/device‑driven rather than a multi‑device data hub or adaptive hybrid coach (Strength, Classes).
• Fitbod: AI‑driven strength programming and logging; overlaps on automated strength plans and low‑friction logging but is strength‑only with limited endurance planning or race‑oriented analytics (How it works).
• Strava: The dominant social training log and activity aggregator; strong on GPS‑based endurance tracking and community, weaker on detailed strength logging, hybrid plan balancing, and coach‑driven adaptive programs (How to optimize training).
