Viaslim

$5M+ in revenue. Launched and scaled across Switzerland.
Hey, I'm Habib.
Fractional CTO for DTC health and wellness brands.
I help telehealth, supplement, and nutraceutical brands improve customer retention and lifetime value, and stay compliant as they scale. Over the past 8 years I've been the technical partner to health and wellness founders, including ViaSlim, which grew past $5M in revenue.
What I do
New · App audit for $49 →- 01
Retention & LTV
The whole DTC health model breaks if customers do not come back. I find where members drop off, subscriptions lapse, and adherence slips, then build the systems that keep them paying and grow lifetime value. This is the work that compounds.
- 02
Compliance
GDPR, SOC 2, HIPAA. I have taken health and wellness products through the compliance and security reviews that investors, partners, and app stores demand. I get you ahead of the conversation so "are you compliant?" is a yes, not a scramble, with field-level PHI encryption and audit-ready architecture.
- 03
Product build, mobile & web
Mobile and web apps from MVP to scale. I am hands-on with system architecture and full-stack development, and I build the subscription, retention, and data systems your brand runs on. Backed by 8 years shipping health and wellness products, not someone figuring it out as they go.
- 04
Technology Strategy
Roadmaps, architecture decisions, build vs. buy. You get clear technical direction from someone who has made these calls across real health and wellness products, and who can speak to your growth and compliance story, not a vendor upselling features you do not need.
- 05
Board & Investor Communication
I work as your Fractional CTO, named on your org chart and present in board and diligence meetings. Your investors get a real CTO who can speak to technical strategy, retention metrics, and compliance posture directly, not a consultant summarising from the outside.

About
Built for DTC health and wellness.
Why me
Over the past 8 years I have been the technical partner to health and wellness founders: leading their teams, owning the architecture calls, and sitting beside them through compliance reviews, diligence, and fundraising.
My deepest work is in DTC health and wellness. I helped scale ViaSlim, a medication-assisted weight-loss clinic, past $5M in revenue across Switzerland, where the data and compliance bar is as high as it gets. I split my time between New York and Dubai and work with health founders in both.

How it works
01
Book a call
30 minutes. You describe what is blocking you and I tell you honestly what I would do about it. If it makes sense for both of us, you have a scoped proposal within 24 hours.
02
First 30 days
Week 1 is a full audit: code, team, vendors, tooling. Weeks 2 and 3 are prioritisation with you. By end of month 1, you have a written 90-day roadmap with three things that will actually move your business.
03
Ongoing rhythm
One standing weekly review. Embedded in your Slack. Available for vendor calls, hiring screens, and architecture decisions. Roughly 20 hours a week, adjusting to 30 during launches, fundraising, or due diligence.
04
How it ends
Month-to-month after an initial 3-month commitment. No equity required. This is not a one-time handoff. Either we keep going, your internal leadership grows past needing me, or you hire a full-time CTO. All three are a success.
Pricing
Intro call
Free 30 minutes
Are customers churning where you think? Is your compliance story ready for the next investor, partner, or app-store review? In 30 minutes we get clear on what is missing and why, before you spend a dime on development.
Product growth
From $4,000 per month
A monthly engagement, not a one-time handoff. My team at Whales Technology builds, ships, and stays. I work with you to lift retention and lifetime value, ship the mobile and web features your brand needs, and keep you compliant as you scale.
Approx. $1,800 per additional senior fullstack engineer. AI-led development workflows mean more shipped for less.
Common questions
What exactly does a Fractional CTO do?
Unlike a consultant who advises from the outside, I work as part of your team. I attend standups, own architecture decisions, manage vendors, and lead your technical strategy. You get a senior operator who is accountable for outcomes, not a report.
What is the difference between Fractional CTO and an Product Growth?
Fractional CTO is a leadership and advisory engagement where I embed into your existing setup. The Product Growth is my team at Whales Technology building and running your product month to month. Both involve me personally. Some clients do one, some do both.
Is this a one-time build or an ongoing engagement?
Ongoing. We build and ship your product, then stay on. After launch I work with you on user adoption, retention, and scaling what is working. You get a whole tech team, not a contractor who disappears after go-live.
What does the Product Growth actually include?
Everything. Design, product development, automated testing, growth strategy, and marketing support. We build and ship your product, then stay on to help you grow it. I bring product insight on what drives adoption and retention. Every fullstack engineer is hand-picked for your product and we use AI-led workflows to ship more for less.
How long until we launch?
Most MVPs ship in 8 to 12 weeks. We scope carefully upfront so you know exactly what you are getting and when.
How is this different from hiring a senior developer?
A senior developer writes code. A Fractional CTO owns the outcome. That means making sure the right things get built in the right order, that your team is set up to execute, and that your technology serves the business rather than the other way around.
How many hours a week do you work with us?
Roughly 20 hours a week in a normal sprint, adjusting to 30 during launches, fundraising, or due diligence. You also get responsiveness, not just scheduled time.
Do you take equity?
No. I work on a monthly retainer. Equity creates the wrong incentives for this kind of engagement.
What if I already have fullstack engineers?
Most engagements involve an existing team. I work with what you have, help you fill gaps, and make sure your engineering function is set up for the stage you are at.
How do we get started?
Book a 30-minute call. No proposal until we agree it makes sense. If it is a good fit, you will have a scoped proposal within 24 hours.
