Executive Summary
PUBLIC
Rithmm is a Boston-based consumer software company that lets sports bettors build their own predictive models in a few clicks. It packages algorithmic forecasting that has historically lived inside professional syndicates into a subscription product aimed at retail users [Rithmm website]; [Gaming Eminence, March 2023]. The company was founded in 2022 with roots in MIT and went to market publicly in March 2023, supported by a seed round backed by Boston Seed Capital alongside DraftKings and a syndicate of early-stage funds [BusinessWire, March 2023]; [Gaming Americas, August 2024]. The product line now spans free daily AI player-prop picks, a Core subscription, and a Premium tier with NFL and college football models launched ahead of the 2023 football season [PRNewswire]. Founder Megan Lanham leads the company alongside a small team that includes engineering, product, and content hires drawn from MIT Sloan and the sports-media world, with former Pinnacle CEO Paris Smith advising and reportedly investing follow-on capital after joining [Rithmm website]; [Gaming Americas, August 2024]. Funding remains modest by venture standards, with roughly $2M confirmed in the priced seed and a reported cumulative figure above $3M as of early 2025, suggesting either a quiet extension or a SAFE layered on top of the original round [BusinessWire, March 2023]; [SBC Americas, March 2025]. Investors should watch whether Rithmm can convert free-tier player-props users into paid subscribers across multiple sports seasons, and whether its content engine (anchored by analyst Josh Appelbaum and the Sunday Sweats NFL show) lowers customer acquisition cost in a category where paid-pick services have historically struggled with churn.

Company Overview
PUBLIC
Rithmm was incorporated in 2022 and emerged from stealth on March 14, 2023, when it announced its predictive-analytics application alongside a seed financing led by Boston Seed Capital with participation from DraftKings, Accomplice, Counterview Capital, Permit Ventures, Correlation Ventures, Oyster Ventures, and Service Provider Capital [BusinessWire, March 2023]; [PitchBook]. The company is headquartered in Boston and is described in trade press as MIT-originated, a lineage echoed in the educational backgrounds of several early employees including senior manager Brian Beachkofski, who lists MIT Sloan on his LinkedIn profile [Gaming Eminence, March 2023]; [Gaming Americas, August 2024]; [LinkedIn, Brian Beachkofski].
The first major post-launch milestone came later in 2023, when Rithmm premiered its Core and Premium subscription tiers and rolled out NFL and college football model coverage in time for the football calendar [PRNewswire]. In August 2024, trade publication Gaming Americas reported that former Pinnacle CEO Paris Smith had joined the company as an advisor and made a follow-on investment, a signal that established sportsbook operators view the team as serious operators in a regulated category [Gaming Americas, August 2024]. By March 2025, SBC Americas described cumulative funding of more than $3 million, suggesting incremental capital was added between the original seed and the spring of 2025 [SBC Americas, March 2025].
Megan Lanham is listed as co-founder and CEO across Crunchbase and Bloomberg profiles [Crunchbase]; [Bloomberg]. The team has remained compact, with public LinkedIn profiles confirming a senior software engineer (Shirshak Sharma), a product manager (Dylan Hoose), and a content lead (Josh Appelbaum) among the core staff [LinkedIn, Shirshak Sharma]; [LinkedIn, Dylan Hoose]; [LinkedIn, Josh Appelbaum].

Product and Technology
MIXED
Rithmm's central product claim is that it builds full predictive models for sports betting rather than publishing static picks. Per the company website, its algorithms simulate every game, every player, and every sport, and the system holds an opinion on every matchup rather than only featured ones [PUBLIC] [Rithmm website]. Users can also customize models, which the company describes as the ability to build a personal analytical model in seconds using one's own instincts as the starting input while Rithmm handles the back-end computation [PUBLIC] [Rithmm LinkedIn]. The product is sold through a tiered subscription on the company's pricing page, with a free AI Player Props product serving as the top of the funnel for NFL, NBA, college basketball, and college football wagers [PUBLIC] [Rithmm pricing page]; [Rithmm AI Player Props page].
In October 2023 the company premiered Core and Premium tiers and launched dedicated NFL and college football offerings ahead of the football season, framing Premium as the destination for users who want full model access across the major U.S. sports calendars [PUBLIC] [PRNewswire]. Distribution is reinforced by a content layer: analyst Josh Appelbaum hosts and contributes to Rithmm-branded shows including CBB Live and the Sunday Sweats NFL show, distributed through Rithmm's YouTube channel [PUBLIC] [Rithmm YouTube]; [Rithmm website]. The company is careful to position the platform under an entertainment-only disclaimer, noting on its pricing page that the site does not involve real money betting or prizes, and partners with regulated sportsbooks (BetMGM is referenced on its promos page) for affiliate-style monetization [PUBLIC] [Rithmm pricing page]; [Rithmm promos page].
On the engineering side, the company is hiring a backend developer for a remote-Boston role, indicating continued investment in the model serving and data pipeline [MIXED] [Rithmm careers page]. Specific stack components, model architectures, training data sources, and accuracy benchmarks are not publicly disclosed.

Market Research and Opportunity
PUBLIC
The U.S. sports-betting market is in the middle of a state-by-state legalization wave that has reset the addressable consumer base for analytics products every football season since 2018. Rithmm sits inside the analytics and tools layer that surrounds the regulated sportsbook duopoly of FanDuel and DraftKings, a layer that the trade press treats as a distinct category from the books themselves [Gaming Eminence, March 2023]; [Gaming Americas, August 2024]. No third-party TAM/SAM/SOM report is cited in the available research for the AI-bettor-tools sub-segment specifically, so any sizing here would be analogous rather than direct.
Demand drivers visible in the cited research are three. First, legalization continues to expand the universe of legal U.S. bettors, which in turn expands the pool of subscribers who can plausibly pay for analytics. Rithmm's launch and product cadence have been timed to football seasons, the highest-handle period of the U.S. calendar [PRNewswire]. Second, retail bettors increasingly compete against sportsbook pricing engines that themselves use machine learning, which creates a real consumer pull for tools that can model lines independently rather than just publish a tout's pick [Rithmm website]. Third, the player-props market (single-player statistical wagers) is one of the fastest-growing bet types and is the specific wedge Rithmm has chosen for its free top-of-funnel product [Rithmm AI Player Props page].
The most relevant adjacent and substitute markets are the established odds-and-data publishers (Action Network, Outlier), bet-tracking apps (Pikkit), and line-shopping or alert tools (Linemate). These products compete for the same monthly wallet share among serious recreational bettors, and several of them have raised meaningfully more capital than Rithmm has disclosed. The substitute that matters most is free: social media handicappers and Discord communities that bundle picks with community for $0 or low monthly fees.
Regulatory and macro forces cut both ways. State-level expansion is a tailwind, but each new state brings its own affiliate marketing rules, responsible-gaming disclosure requirements, and in some cases outright bans on paid-pick services. Rithmm's entertainment-only disclaimer and BetMGM affiliate relationships are the standard way operators thread that needle [Rithmm pricing page]; [Rithmm promos page].
| Sizing claim | Value | Source |
|---|---|---|
| Rithmm cumulative funding | >$3M reported | [SBC Americas, March 2025] |
| Rithmm priced seed | $2.0M | [BusinessWire, March 2023] |
Analyst takeaway: the publicly disclosed numbers describe Rithmm's own balance sheet rather than the market it sells into, so investors evaluating market size should treat U.S. legal-handle figures from state regulators as the cleaner anchor. The signal in the table above is that Rithmm has been capital-efficient relative to several named competitors that have raised larger rounds.
Data Accuracy: YELLOW -- Demand drivers and competitive set are corroborated by trade press; quantitative TAM is not cited in any retrieved third-party report.
Competitive Landscape
MIXED
Rithmm is positioned as a model-builder for retail bettors rather than as a pick-seller or a tracking utility. This places it in a narrower lane than the broader sports-data category but pits it against well-funded incumbents on both flanks.
| Company | Positioning | Stage / Funding | Notable Differentiator | Source |
|---|---|---|---|---|
| Rithmm | Customizable AI predictive models plus free player-props funnel | Seed, ~$2M priced; >$3M reported cumulative | User-built models in seconds; MIT origin; DraftKings on cap table | [BusinessWire, March 2023]; [SBC Americas, March 2025] |
| Action Network | Odds, news, bet tracking, expert picks | Acquired by Better Collective | Scale audience and editorial brand | [Crunchbase] |
| Outlier | Player-prop research and alerts | Venture-backed | Visual prop research workflow | [Crunchbase] |
| Pikkit | Automated bet tracking across sportsbooks | Venture-backed | Sportsbook-sync infrastructure | [Crunchbase] |
| Linemate | Player-prop projections and trends | Early stage | Trend-based prop visualization | [Crunchbase] |
The segment map breaks into three groups. The incumbents are content and odds publishers led by Action Network, which after the Better Collective acquisition has the scale audience and SEO surface area that a seed-stage challenger cannot match in the short term. The challengers are the prop-focused tools (Outlier, Linemate) that occupy the same player-props wedge Rithmm uses for its free funnel. The adjacent substitutes are the tracking apps (Pikkit) that own a different job-to-be-done but compete for the same wallet, plus the free Discord and X-based handicapper communities that anchor the price floor.
Rithmm's defensible edge today rests on three specific assets. First, the customizable-model product is a genuinely different shape from a pick service or a static projection, and it lets the company make a clean marketing claim (build your own model in seconds) that the incumbents have not matched on their public sites [Rithmm LinkedIn]. Second, DraftKings on the cap table is unusual for a tools company and gives Rithmm at least an introduction-level relationship with the largest U.S. sportsbook, which matters for affiliate economics and for any future data partnerships [BusinessWire, March 2023]. Third, having Paris Smith as an advisor brings sportsbook operating credibility that smaller competitors typically cannot offer [Gaming Americas, August 2024]. The perishability question is real: model-building UX can be copied, and the DraftKings relationship is a strategic-investor position rather than an exclusive commercial deal.
Exposure is on distribution. Action Network's audience and Outlier's specific dominance in the prop-research workflow are the two specific advantages Rithmm cannot match with seed-stage capital. The channel Rithmm does not own is the sportsbook itself: every retention conversation eventually runs into the fact that DraftKings and FanDuel can ship their own quick-bet and same-game-parlay tools directly inside the app where the wager is placed.
The most plausible 18-month scenario: winner if Rithmm's content engine (Sunday Sweats, CBB Live, Josh Appelbaum's editorial reach) drives paid conversion at a CAC meaningfully below paid social, which would let it compound through a second football season without another priced round. Loser if a better-funded prop competitor like Outlier ships a comparable user-model builder before Rithmm has locked in a defensible content or data moat.
Data Accuracy: YELLOW -- Subject row confirmed by primary sources; competitor positioning drawn from public Crunchbase profiles without independent revenue corroboration.
Opportunity
PUBLIC
If Rithmm executes, the prize is to become the default analytics layer for the millions of U.S. retail bettors who now have legal access to sportsbooks and want a tool that does more than publish someone else's pick.
The headline opportunity. The single largest outcome Rithmm could plausibly become is the consumer-side modeling platform that sits between retail bettors and the sportsbooks, a category that does not yet have a clearly dominant brand the way Action Network owns odds-and-content. The cited evidence makes that outcome reachable rather than aspirational on three counts: the customizable-model product is a genuinely differentiated wedge versus pick services [Rithmm LinkedIn]; the company has a strategic investor (DraftKings) that gives it credibility in the regulated category [BusinessWire, March 2023]; and the team has paired MIT-rooted engineering with sportsbook operating experience via Paris Smith's advisory role [Gaming Americas, August 2024].
Growth scenarios.
| Scenario | What happens | Catalyst | Why it's plausible |
|---|---|---|---|
| Affiliate flywheel | Free player-props funnel drives high-intent traffic to BetMGM and other regulated books, with revenue-share economics scaling alongside legal-state expansion | Additional state legalizations and expansion of sportsbook affiliate partners beyond BetMGM | Rithmm already runs a BetMGM partnership and structures its free product to feed regulated sportsbooks [Rithmm promos page] |
| Subscription compounding through football | Core and Premium tiers grow paid subscribers across consecutive NFL and college football seasons, with content from Sunday Sweats lowering CAC | Second and third NFL seasons under Premium tier with expanded sport coverage | Premium and football-specific products were launched ahead of the 2023 season [PRNewswire] and the content engine is staffed by a recognizable analyst [Rithmm website] |
| Strategic acquisition path | Rithmm is acquired by a sportsbook operator or a media roll-up that wants the model-builder UX and the audience | A sportsbook seeks to internalize a differentiated retention tool, or a content platform consolidates analytics tools | DraftKings already participated in the seed, signaling category interest from at least one operator [BusinessWire, March 2023] |
What compounding looks like. The flywheel that turns one win into the next runs through data. Every user who builds a custom model and tracks its results gives Rithmm a feedback signal on which inputs predict outcomes, which in turn improves the default models the company ships to new users. Layered on top is a content distribution loop: Josh Appelbaum's CBB Live and Sunday Sweats shows are top-of-funnel for free users, free users feed paid subscriptions, and paid subscribers generate the user-model usage data that strengthens the underlying product [Rithmm YouTube]; [Rithmm AI Player Props page]. The early evidence that the flywheel is starting is the cadence of product launches between March 2023 and the football season later that year, plus the reported follow-on investment from Paris Smith in 2024 [PRNewswire]; [Gaming Americas, August 2024].
The size of the win. A credible public comparable in adjacent sports-data is Action Network, which Better Collective acquired (publicly reported in 2024 trade press) for a figure in the hundreds of millions of dollars. Translating that into Rithmm terms: if the affiliate-flywheel scenario plays out and Rithmm becomes a meaningful traffic source for two or three regulated books across ten or more legal states, an outcome in the low-to-mid nine figures becomes a defensible (scenario, not a forecast) reference point. The subscription-compounding scenario points to a smaller but higher-multiple outcome typical of consumer SaaS at the $10M to $30M ARR range. Both outcomes are well inside the bounds of what a roughly $3M cumulative raise can support if the company stays capital-efficient.
Data Accuracy: YELLOW -- Scenarios anchored to confirmed product, partnership, and funding facts; comparable valuations are directional and not company-specific forecasts.
