Frequently asked questions

What is OneLeaf's primary product offering?

OneLeaf offers personalized self-hypnosis audio programs delivered via a mobile app. The programs are designed to help users access their unconscious mind to address behavioral challenges like smoking, weight management, and anxiety, as described on Slides 4 and 6.

How does OneLeaf plan to make money?

According to Slide 9, the business model is a 'flywheel' that starts with either a one-time fee per specific program or an annual subscription. The goal is to convert single-program users into annual subscribers once they see results from their first session.

Which markets did OneLeaf target for its initial launch?

Slide 11 indicates that OneLeaf targeted the US market for its V1 launch in 2022. They specifically focused on two high-demand verticals: quitting smoking and weight loss, due to high search volume and low competition in the digital smoking cessation space.

What scientific evidence does the deck provide for hypnosis?

The deck cites multiple studies, including a 54% long-term relief rate for IBS patients (Slide 4) and a 68% decrease in hot flashes for breast cancer survivors (Slide 13). These metrics are used to frame hypnosis as a legitimate medical tool rather than just wellness.

What are the key conversion metrics reported in the deck?

On Slide 11, OneLeaf reports a 48% sign-up conversion rate and a 21% payment conversion rate within the first seven days of sign-up. These figures suggest strong initial product-market fit during their US testing phase.

What the Oneleaf pitch deck was used for

This deck is Oneleaf’s seed‑stage fundraising presentation around January 2023, used to raise roughly $5.1M to scale its digital self‑hypnosis app from France into the US market.[1][6][10] The Paris‑based startup, founded in 2022 by Eliott Cohen‑Skalli, offers app‑based self‑hypnosis programs targeting smoking cessation, weight loss, sleep and anxiety, positioning itself as an accessible, evidence‑based alternative to in‑person hypnotherapy.[1][5][6][11] Press coverage indicates the round’s purpose was to finance US market entry, expand content and B2B offerings, and support clinical collaborations, including negotiations for trials with a New York University laboratory.[5][6][10] Business Insider’s pitch‑deck feature confirms the deck includes clinical data and go‑to‑market metrics to validate self‑hypnosis as a non‑traditional wellness category.[1]

Business model: B2C and B2B2C digital self‑hypnosis programs delivered via a mobile app, addressing use cases such as smoking cessation, weight loss, sleep, anxiety and confidence.[6][5][10][11]

Year: 2023 (round announced in January 2023; later coverage often refers to the amount as $5.1M). [3][4][6][8][10]

Raising: Seed/early‑stage VC round used to finance US expansion, product and content development, and B2B initiatives.[3][6][8][10]

Raised: Approximately $5.1M total around January 2023, often described as $4.6M (€4.2M–€4.6M) in equity plus several hundred thousand dollars in equity‑free financing from Bpifrance.[3][4][6][8][10][11]

What happened after the Oneleaf deck

Following its January 2023 seed/early‑stage VC round, Oneleaf has been operating as a funded digital self‑hypnosis platform focused on smoking cessation, weight loss, sleep and anxiety, supported by French and international investors and planning further clinical validation and US expansion.[3][4][5][6][10][11]

What the Oneleaf deck got right

• Strong early backing from reputable French investors. Multiple credible sources report a roughly $5.1M seed/early‑stage VC round led by Frst with participation from Kima Ventures, Raise Ventures, Bpifrance and several angels, signaling strong investor validation for an early‑stage wellness startup.[1][3][4][6][8][9][11]
• Exposure to multiple multi‑billion‑dollar health and wellness markets. Oneleaf targets large, well‑defined markets—smoking cessation, weight management, sleep and anxiety—where traditional interventions often have limited long‑term success, creating a compelling opportunity if digital self‑hypnosis can demonstrate sustained outcomes.[4][5][6][11]
• Evidence‑based positioning with academic clinical collaborations. The company positions its programs as “accessible, evidence‑based” and has initiated or planned collaborations with academic partners such as a New York University laboratory, which helps differentiate it from generic wellness apps and supports stronger clinical and regulatory narratives.[5][6]
• Scalable, app‑based delivery of structured self‑hypnosis programs. Delivering programs via a consumer‑friendly mobile app enables low marginal costs, global reach and rapid iteration, while program formats like 21‑day protocols are simple to communicate and potentially habit‑forming from a behavioral‑science perspective.[5][6][11]
• Clear geographic and channel expansion story. Starting from Paris with ambitions to expand to the US and to develop B2B offerings (e.g., for employers) gives Oneleaf multiple growth vectors, including direct‑to‑consumer revenue and potentially more durable B2B2C contracts.[6][10]
• Compelling founder narrative and founder‑market fit. Founder Eliott Cohen‑Skalli’s personal experience with hypnosis and decision to build Oneleaf is highlighted in media coverage, and Business Insider notes that this narrative helped shape the deck’s story, which can resonate with investors seeking founder‑market fit.[1][5]

What could have been stronger

• Prospective rather than completed clinical validation. External descriptions emphasize that Oneleaf was “in negotiation” to launch clinical trials with a New York University lab rather than already having completed trials, which implies that, at the time of this seed deck, clinical evidence was still largely prospective and based more on plans and early data than on completed randomized trials.[5] This makes it harder for investors to fully underwrite efficacy in sensitive indications like smoking cessation and weight loss.
• Broad use‑case focus may blur the initial wedge. Coverage highlights the breadth of use cases—smoking cessation, weight loss, sleep, anxiety, self‑confidence—which can dilute perceived focus at seed stage and complicate the messaging around a beachhead market and core KPI set.[5][6][11] While this versatility is framed as a strength in PR, investors often prefer a single dominant wedge (for example smoking cessation) with a clear path to scaling before broad diversification.
• Limited disclosed program outcome metrics. Despite the company’s framing as “evidence‑based,” publicly available information focuses more on program duration and user promises (e.g., 21‑day programs to quit smoking, lose weight or improve confidence) than on quantified outcomes such as quit rates or weight‑loss percentages.[5] This suggests the deck may lean more on the general literature on hypnosis and early engagement metrics rather than robust, Oneleaf‑generated outcome data, which some investors will see as a gap at seed.
• US go‑to‑market and regulatory pathway not fully articulated publicly. Articles emphasize a US expansion strategy from a French base and suggest ambitions to enter multi‑billion‑dollar markets such as weight loss and smoking cessation.[6][10] However, public coverage does not detail a specific US regulatory, reimbursement, or clinical‑partnership strategy, leaving open questions about how the company will navigate differing medical, privacy and claims‑marketing rules across jurisdictions, a concern likely visible to sophisticated healthcare investors reviewing the deck.

How an investor would read this deck

What draws attention

• Evidence that self‑hypnosis can deliver meaningful outcomes in smoking cessation and weight control, areas where relapse rates are high and traditional interventions often disappoint.[4][5][6]
• The size of the addressable markets spanning smoking cessation, obesity/weight management, sleep and anxiety, all of which are framed in coverage as multi‑billion‑dollar categories.[6][10]
• Product engagement and retention metrics for the mobile app, particularly completion rates for the 21‑day programs and the proportion of users achieving self‑reported behavioral change.[5][6]
• The strength and credibility of clinical and academic partnerships, including the planned collaboration with a New York University laboratory to run clinical trials.[5]
• Team experience in consumer apps, healthcare, and US expansion, with particular focus on the founder’s story of personal experience with hypnosis, which Business Insider notes as part of the narrative.[1]

Risks that stand out

• Clinical and regulatory risk if future trials with academic partners fail to demonstrate strong efficacy or raise safety or ethical concerns, undermining the “evidence‑based” positioning in high‑stakes indications.[5]
• Market and differentiation risk given intense competition from general meditation, CBT, and wellness apps, many of which already claim benefits around sleep, anxiety, weight or smoking, potentially making user acquisition expensive and churn high.[4][6][11]
• Execution risk around international expansion: scaling from France to the US involves significant localization, regulatory navigation and partnership building; missteps could consume much of the seed capital without reaching product‑market fit.[6][10]
• Reputational and compliance risk if marketing promises (e.g., quitting smoking or losing weight in 21 days) are perceived as exaggerated or are challenged by regulators or consumer‑protection bodies.[5]
• Dependence on a single major round of approximately $5.1M plus non‑dilutive funding, with no publicly reported follow‑on rounds as of the seed, making the company sensitive to future fundraising conditions in the digital health and wellness sectors.[3][4][11]

Questions this deck invites

• What early efficacy data does Oneleaf have from its own user base (e.g., verified quit rates for smoking at 3, 6 and 12 months, or percentage weight loss maintained over time), and how are these outcomes measured and validated?
• How far along are the negotiations and protocol design for the planned clinical trials with the New York University lab, what endpoints will be studied, and will the results be publishable in peer‑reviewed journals?
• What is Oneleaf’s concrete US go‑to‑market plan (direct‑to‑consumer vs. employer/insurer partnerships), and how does it plan to navigate medical claims, FDA or FTC requirements, and HIPAA/privacy obligations?
• How does Oneleaf’s cost of acquisition and payback period compare across key channels (paid social, app‑store optimization, partnerships), and what scale of marketing spend can the current unit economics sustain?
• In a crowded wellness and mental‑health app landscape, what IP, proprietary content, or differentiated product features does Oneleaf have that are difficult for competitors to replicate, especially in self‑hypnosis?

What founders can take from the Oneleaf deck

• A non‑traditional category such as self‑hypnosis can attract institutional seed capital when framed with strong, familiar use cases (smoking cessation, weight loss, sleep) and large market sizes that investors already understand.[4][5][6]
• Positioning a wellness app as “evidence‑based” and tying it to planned or ongoing academic trials (e.g., with an NYU lab) helps address investor skepticism about efficacy in a space often seen as anecdotal.[5]
• A clear geographic expansion story—using a seed round to move from a domestic base in France to the US—gives investors a concrete narrative about how capital translates into growth and valuation upside.[6][10]
• Highlighting specific investor names (Frst, Kima Ventures, Raise Ventures, Bpifrance) leverages their credibility and signals that sophisticated backers have vetted the model, which can be emphasized effectively in a pitch deck.[1][3][6][8][11]
• Framing self‑hypnosis as a scalable digital tool that can address several adjacent conditions (smoking, weight, sleep, anxiety) shows investors both a focused initial wedge and a broader product roadmap, which can support long‑term growth narratives when done carefully.[5][6][11]
• Combining consumer‑grade product experience with healthcare‑oriented outcomes allows a deck to speak both to generalist tech investors (on engagement and growth) and to health‑focused investors (on clinical validation and behavioral change).
