A structured care-planning tool for OB practices is a real gap. The liability picture is genuinely scary.
There's a specific kind of anxiety that doesn't get talked about enough: the pregnant person who already knows they're high-risk for postpartum depression, who has lived through depression or OCD before, and who is staring down their due date with exactly zero concrete plan for what happens when the baby comes and everything gets hard.
They know it's coming. They just don't know what to do about it.
Current pregnancy apps are not built for this person. They're built to tell you what size fruit your baby is this week and remind you to take your prenatal vitamins. The clinical infrastructure for postpartum mental health is, in a lot of practices, a paper Edinburgh Scale administered once at six weeks postpartum, maybe followed up on, maybe not.
The gap here is real. I believe that.
Postpartum depression affects roughly 1 in 5 new mothers. For people with a prior history of depression or anxiety, that rate climbs significantly. The evidence-based recommendation is to have a postpartum mental health plan before delivery: who you'll call, whether you're continuing medication, what the warning signs are, who in your support network knows what to watch for, and when the situation escalates to a clinical emergency.
Most people with prior mental health history do not have this plan documented. They mean to set it up. Then week two postpartum arrives and they're sleeping in 90-minute windows and everything they meant to organize is still in their head.
The posts on r/PPD are consistent: 'I knew I was high-risk. My OB knew. Nobody gave me anything concrete to prepare with.' That's not a design problem waiting for a slicker app. That's a care coordination failure. And it's one that a B2B tool sold to practices rather than directly to patients is actually well-positioned to solve.
Every existing PPD-adjacent app is consumer-first. Expectful, Headspace's postpartum content, the PSI community resources. They're all marketed to the patient directly, which means the patient has to find them, pay for them, and integrate them into their care on their own. That's a cold-start problem in a population that is, by definition, dealing with a lot.
The smarter wedge is what Phreesia and Babyscripts figured out years ago: sell to the practice, get embedded in the clinical workflow, and let the practice hand the tool to patients as part of their standard care. The patient receives it as a clinical recommendation, not a product they discovered in an App Store search.
At 28-32 weeks, an OB or midwife could hand a high-risk patient a link to a structured plan-builder. They fill it in before delivery: medication protocol, emergency contacts, support roster with actual names and roles, check-in schedule for the first 90 days. The plan exports as a PDF that goes in the chart. The automated SMS check-ins fire on schedule. A care coordinator sees a dashboard with red/yellow/green flags.
That's a real clinical tool. That's worth paying for.
There are roughly 6,000 OB/GYN practices in the US with five or more providers. If 10% adopt at $199/month average, you're looking at $14.3M ARR. That's not accounting for midwife practices, perinatal mental health specialists, or international markets where maternal mental health is increasingly a policy priority.
The global maternal mental health market is at $10.3B in 2024, reportedly growing at 28% annually. I'd take that CAGR figure with appropriate skepticism since healthcare market projections are notoriously optimistic, but the directional story is right: this is an area getting more attention, more funding, and more policy infrastructure, not less.
The CMS CPT code 99484 exists specifically for behavioral health integration in primary care settings and creates a reimbursement pathway that makes this tool a revenue generator for practices, not just a cost center. That's a meaningful selling point. Though I'll note that CMS proposed reducing care management reimbursement rates in 2024, which spooked a number of digital health companies. The tailwind is real. It's not guaranteed to stay exactly as favorable.
I want to be honest about the liability picture because glossing over it would be doing you a disservice.
The fatal flaw here is what healthcare attorneys call the missed-escalation scenario. A patient responds green on a check-in. Three days later she's in crisis. The check-in created a documented expectation of monitoring. Your terms of service say you're a care coordination tool, not a diagnostic platform. Your BAA is signed. Your disclaimer is in the onboarding flow.
None of that fully insulates you.
Higher-funded digital health companies have been restructured or destroyed by exactly this liability pattern. Quartet Health, Cerebral. The TOS disclaimer argument fails in court when there's a dead patient and a documented check-in that said everything was fine. This is not FUD. It's a real legal exposure that you cannot hand-wave away with a Stripe subscription and a well-written privacy policy.
The minimum cost of malpractice-adjacent insurance for something touching this territory is $5,000-$15,000 per year, and it may not even be available at pre-revenue stage. You need a healthcare attorney before you launch, not after your first flag goes unanswered.
The second problem is sales cycles. Independent OB practices are faster than hospital systems, but 'fast' here means 8-16 weeks from first contact to signed agreement. That includes IT security questionnaires even if you're not touching the EMR, credentialing reviews, and physician committee sign-off. At $99-$199/month initial ACV, you will burn runway on sales cycles that cost you more in founder time than the first year of contract revenue.
And then there's engagement. Postpartum patients are exhausted. If things are going well, there's no incentive to respond to a check-in text. Research settings see 40-55% response rates with active study support. Commercial deployments routinely see 20-35%. If practices are seeing low response rates, they'll conclude the tool isn't clinically useful, which means they stop referring patients to it, which kills your distribution without killing your costs.
There's no YC-funded company in this space. That's usually a positive signal. But I keep coming back to something: Babyscripts has raised over $20M and has existing relationships with OB practices across the US. Phreesia has a $1B+ market cap and is already in OB waiting rooms. Either of them could add a postpartum mental health module as a feature addition, not a new product, if they saw enough demand.
The 'no one owns this space' observation may reflect rational avoidance more than an undiscovered gap. The healthcare GTM is brutal. That's not a new problem. The 'why now' argument about growing awareness and telehealth integration has been equally true since at least 2018 and hasn't produced a clear winner. The bottleneck isn't technology. It's the economics of selling clinical workflow tools to small practices at consumer-grade price points.
The tech stack is genuinely simple: Next.js, Supabase, Twilio for SMS, Stripe, Resend for email. Everything on that list has HIPAA-eligible infrastructure with BAAs available. A solo developer can have an MVP in 5-7 weeks. That's the easy part.
The harder part is the validation work you should do before writing a single line of code. Build the plan-builder as a Typeform. Send it to 20 practices from the PSI provider directory. Offer to generate a PDF plan manually within 24 hours. Ask two questions: would you refer this to high-risk patients, and would you pay for an automated version. If five of twenty say yes and three agree to a paid pilot at $99-199/month within four weeks, you have real signal. If you can't get that, no amount of beautiful frontend work will fix it.
The PSI network is the actual distribution unlock here. 4,000+ listed providers, a focused community that cares deeply about this problem. The providers in that directory already believe postpartum mental health coordination matters. You're not educating them. You're offering them a tool for something they're already trying to do manually.
The problem is real and the channel insight is smart. B2B2C through OB practices, positioned as a clinical workflow asset rather than a wellness app, is the right frame. The data moat potential is real: longitudinal mood data from a documented high-risk cohort, post-Edinburgh NLP analysis on free-text responses, eventually a risk-stratification model that consumer apps can't replicate because their user base is self-selected and unverified.
But the liability exposure is existential in a way that most SaaS risks are not. This isn't 'we might get outcompeted' or 'maybe CAC is higher than we modeled.' It's 'one missed escalation and a motivated plaintiff attorney and this company is gone.' You need a healthcare attorney and insurance conversations happening in parallel with your validation work, not as an afterthought.
If you're a solo developer looking for a weekend side project, this is the wrong idea. If you have genuine interest in maternal health, the patience for long sales cycles, the budget for legal infrastructure, and a co-founder or advisor with healthcare operational experience, the gap is real enough to be worth pursuing carefully.
Just don't ship the SMS check-ins before you've talked to a healthcare attorney. Seriously.
