PetaNetra

Assistive Technology & Independent Navigation

Founded by Graciela Gabrielle Angeline (CEO) , Jessi Febria (CTO) , and Yafonia Hutabarat (COO) , PetaNetra started with a personal reality: Grace’s parents are visually impaired, and as their only child, she often needed to be by their side just to move through everyday spaces.

But the problem is bigger than one family—Indonesia has millions of people with visual impairment, and truly accessible public places are still rare. PetaNetra exists to change that by helping people navigate independently , especially in indoor public spaces.

What are they building?

PetaNetra is a mobile app that helps people with visual impairment navigate indoor (and semi-outdoor) public spaces more safely and independently using AR and voice guidance. It starts with location detection to identify where the user is standing, then provides accurate step-by-step navigation using clockwise direction and distance cues in meters.

With voice-over guidance and haptics (vibration feedback), instructions are easier to follow without relying on visual prompts, and the product is designed for places where indoor navigation is typically hardest—stations, malls, public buildings, and campuses.

The why?

PetaNetra began with Grace’s parents—but the urgency became clearer once the team started listening beyond their immediate circle.

The team shares that after speaking with visually impaired respondents, 70% said they’d had accidents while mobilizing . They mention one incident from the news where a visually impaired person fell down onto train rails—an example of how navigating a city can become genuinely dangerous.

As Yafon puts it: it’s easy for most of us to move around the city—but for someone with vision loss, it can become a life-threatening activity .

Grace’s parents were also among the first real user-testers. They were excited—and their feedback helped the team keep iterating. The product isn’t treated as “done”; it’s something they keep improving in partnership with the people it’s built for.

SEED Inclusivity Program Journey

PetaNetra shared that SIGMA helped their team think beyond their usual “box”—sparking new conversations and surfacing ideas they hadn’t explored before. One of the most useful parts was the early persona-building flow. From a single prompt, SIGMA generated detailed personas, customer segments, and beneficiary needs in a way that felt surprisingly accurate—and helped them connect the dots between who they serve, what each group needs, and how to position value clearly.

Beyond the tool, they described the bootcamp atmosphere as unusually supportive. Unlike other incubators where they felt intimidated, this one felt like a community—“a family instead of competitors”—with peers and mentors who were both high-caliber and humble.

Recent Achievements

Built and launched PetaNetra as an AR-enabled indoor navigation app for people with visual impairment, available publicly on major app platforms

Featured internationally for its accessibility mission and indoor navigation approach (including coverage from global innovation/IP platforms)

“Imagine the irony—it’s so easy for us to move around the city, but it’s a life-threatening activity for people with disabilities. That’s why we built this.”
