The patients come first here, and in Brazil the patient in question is increasingly an 80-year-old in a fourth-floor São Paulo apartment whose daughter is trying to coordinate a rotating cast of caregivers over WhatsApp. That is the person Sanii is trying to serve, and the company's bet is that families will pay a monthly membership for someone to take the scheduling, vetting, and clinical follow-through off their hands.
Sanii, founded in 2022 by Angelina Clarke, Michael Kapps, and Renato Tilkian, has raised roughly US$2.4 million in disclosed capital to build what it calls a closed marketplace for elderly home care, supported by an AI layer that handles matching, scheduling, and back-office work [Latam Republic]. The company reports more than 38,000 visits per year and 450,000 hours of care delivered [StartupResearcher].
The patient, not the app
The wedge is unglamorous and, for that reason, defensible. Brazil's elderly home-care market is overwhelmingly informal. Sanii's pitch is to professionalize that relationship by recruiting, vetting, and training caregivers, then matching them to families through a software layer that also handles shifts and remote monitoring [Perplexity Sonar Pro Brief].
The revenue model is a monthly membership sold to the adult children. That subscription bundles companion care, cognitive stimulation, physical activities, and social events for seniors [Perplexity Sonar Pro Brief]. It is a tech-enabled services business with a thin AI veneer; the moat sits in caregiver supply and operational discipline.
Why now in Brazil
Brazil is aging faster than most of its institutions are ready for. A platform that can guarantee continuity of a vetted caregiver, and absorb the back-office burden, is solving a problem that the public system is not going to solve any time soon.
The broader ambition is to grow into a full home-health stack: medicines, vaccines, diagnostic tests, physiotherapy, dental care, and IoT sensors [Perplexity Sonar Pro Brief]. For now, the company is staying in the lane it can actually execute on, which is companion care and wellness [News Room USA, 2025].
The cap table
The round structure is small but well-populated for a Latin American healthtech at this stage. Sororitê Ventures led the most recent extension, with Seedstars, TipTop VC, Geist Capital, GVAngels, Valor Capital Group, Green Rock, and Norte Ventures on the cap table across rounds [Latam Republic][StartupResearcher].

The team
The founding team brings operational and finance backgrounds rather than clinical ones.
| Founder | Role | Background |
|---|---|---|
| Renato Tilkian | Co-founder, CEO | Entrepreneur, board advisor, former M&A executive [LinkedIn, 2026] |
| Angelina Clarke | Co-founder, COO | Former Director of Brazilian Operations at Assured Labor [Forbes, 2012] |
| Michael Kapps | Co-founder | Harvard University [Crunchbase, 2026] |
Clarke has gone on the record framing the company's mission as enabling "movement of body, mind, and social life for purposeful aging after 60" [Perplexity Sonar Pro Brief].
Where the bet could break
Marketplaces in regulated, labor-intensive categories are unforgiving. The risks worth naming up front:
- Caregiver supply economics. A closed marketplace only works if Sanii can recruit and retain caregivers at a wage families will pay for via subscription.
- Self-reported traction. The 38,000 visits and 450,000 hours figures are estimates carried in trade press [StartupResearcher].
- Regulatory drift into clinical services. The stated ambition to add diagnostics, vaccines, and physiotherapy moves the company from a labor marketplace into a regulated health provider.
- Capital intensity of the next leg. US$2.4 million in disclosed funding [Latam Republic] is enough to prove the São Paulo wedge; expanding into a multi-city home-health stack will require a meaningfully larger round.
What to watch next
The near-term tells are straightforward: a Series A round large enough to fund a second Brazilian city, a published retention number on the monthly membership, and the first clinical service category Sanii adds to the bundle.
The standard of care today, for families who can afford anything beyond the SUS public system, is an informally hired caregiver paid in cash. Clearing that bar, repeatedly and at scale, is the actual business.
