Inspiration

Becoming a parent is one of life’s most transformative moments, yet the resources available to dads are often limited or hard to find. New fathers often feel isolated, unsure of their role, and hesitant to ask "dumb questions."

We wanted to change that. We built DadCircles to give every dad a path to find their support group, whether their expecting their first, navigating the newborn phase, or wrangling a toddler. We wanted to move beyond static FAQs and create a safe way to connect with other Dads.

The Founder Story: This isn't just an idea; it's personal. When becoming a Dad, Nelson found himself completely out of sync with his existing male friendship circle. He was the first one in his close friendship circle to become a Dad. While he naturally prioritized his kids and household, he found himself trading off social connections and slipping into isolation. He watched his partner build lifetime friendships through her mothers' group (government facilitated in Australia), celebrating milestones and discussing problems, and realized there was no equivalent for him. He saw a clear gap with immediate value: a space for dads to simply hang out, connect, and survive fatherhood together.

The Research Problem: This isolation isn't just a feeling it's a health & child development risk. Paternal mental health is foundational to family well-being.

  • JAMA Pediatrics (Meta-analysis): High correlations between paternal depression and adverse child development outcomes.
  • BMC Public Health: Highlights isolation as a key predictor of paternal perinatal depression.
  • Rutgers Longitudinal Study: Shows that a father's mental health can impact children’s emotional and behavioral development for years.
  • Statistics: 8–13% of fathers experience depression during the perinatal period.

DadCircles functions as a "light facilitation" layer, the "invisible scaffolding" that helps men overcome the friction of initiating friendships or support groups.

What it does

DadCircles is an AI-powered scaffolding system designed specifically to help real‑world dad groups actually form and stick, instead of dying after one or two meetups.

The core insight is that most groups only work because someone quietly handles logistics and follow‑up; moms’ groups, sports teams, and professional cohorts all have that, but dad groups usually don’t.

DadCircles exists to fill that gap.

How it works, in plain terms. There are two options for Dads:

  1. Weekend mission (no sign up required, free)

  2. No sign up, instant recommendation of activities in your local area based on your life stage and preferences.

  3. Dadcircles group (email sign up, free)

  4. Matches dads by postcode and parenting stage, so you’re with a small group of peers in a similar life season.

  5. It makes warm introductions instead of dumping you in a big forum or chat.

  6. It nudges and coordinates the first meetup and follows up with the group and individuals so there’s real momentum.

  7. Once the group has its own rhythm, the “structure” intentionally fades into the background so it feels like your group, not a program you’re attending.

Also important: DadCircles is not about content, forums, or therapy. It’s intentionally light, behind‑the‑scenes facilitation whose whole job is to make it much more likely that a small, local circle of dads becomes something you actually look forward to and keep showing up for.

Some features: Conversational Onboarding: Instead of a boring signup form, dads chat with our Gemini-powered assistant. It naturally gathers high level details to enable the platform to form Dad groups (due dates, children's ages, interests, location) through a friendly conversation.

Instant, low risk recommendation: researches activities in your local area and recommends them based on your life stage and preferences as Weekend Missions.

Context-Aware Support: The AI understands the nuanced difference between an "expecting dad" and a "current dad" (or one who is both!) and tailors its tone and questions accordingly.

Smart Matching (Demo): It uses the extracted structured data to match dads with local "circles" of other fathers who are in the same stage of life and share similar interests.

How we built it

We built DadCircles with a modern, scalable stack focused on user experience and real-time interaction: ** Frontend:** React 19 with Tailwind CSS for a sleek, responsive mobile-first design. Backend: Firebase Cloud Functions and Firestore for secure, serverless architecture. The Brain (Gemini 3): We leveraged the Gemini 3 API for the core conversational logic.

  • Reasoning & Context: We use Gemini's advanced context window to maintain a coherent conversation history, allowing dads to tell their story in their own words.
  • Native Function Calling: We utilized Gemini's structured output capabilities (FunctionCallingConfigMode.AUTO) to seamlessly extract precise data (birth dates, location, interests) from natural language without breaking the flow of conversation.
  • System Prompting: We carefully engineered system instructions to ensure the AI maintains a "warm, friendly, and concise" persona, avoiding the robotic tone of typical chatbots.

Challenges we ran into

Balancing Structure vs. Freedom: Dads talk about their kids in many ways ("my little girl is 2", "due next March", "two boys, 4 and 6"). Teaching the AI to normalize all these inputs into a strict database schema while keeping the conversation natural was a key challenge. Gemini's strong reasoning capabilities helped bridge this gap significantly.

Privacy & Security: We initially prototyped with client-side API calls but quickly realized the security risks. We migrated the entire AI layer to a secure, server-side Cloud Function architecture using Firebase Secrets to protect our API keys and user data.

Handling Ambiguity: "Next March" can mean different years depending on the current date. We implemented logic to help the AI infer and confirm dates intelligently.

Testing and Cost Management: Focused on specific Ann Arbor and Ypsilanti area in Michigan as a starting point to test onboarding, matching algorithm and weekend mission. This allowed us to maintain costs in this early development stage. We built interim solutions by conducting heavy research in those areas to build repository of data for generating missions.

Accomplishments that we're proud of

The "Vibe": The onboarding doesn't feel like data entry. It feels like a chat. It feels safe. There is a low stakes option to generate a mission with no sign up or commitment requirement. This also leverages existing infrastructure and event/social pages that overlap and complement DadCircles objectives. Data input was limited to absolute must haves to keep Dads and their family information private and safe (e.g. only ask for family structure and zip code and NOT personal details like name or address)

Reliable Data Extraction: We achieved great feedback from early testers converting casual chat messages into structured JSON profiles using Gemini's tool use, which is critical for our matching algorithm. Onboarding feedback led to the mission generator as some Dads wanted a light 'gateway' into the experience.

Secure Architecture: We successfully deployed a production-ready, secure infrastructure that protects user privacy. A non-negotiable for family-related apps.

What we learned

Gemini is surprisingly empathetic: With the right system prompt, the model can navigate sensitive topics (like expecting a child) with genuine-seeming warmth, which dramatically improves user engagement.

Structured Outputs are a Game Changer: Moving from regex-based parsing to LLM-native function calling simplified our backend logic by an order of magnitude.

What's next for DadCircles

NOW & NEXT Geo & Reach: Currently, we are focused on targeted regions and cities for testing (Ann Arbor & Ypsilanti, Michigan, USA). Sign ups are global but the services are restricted to our primary target locations. This will form the foundation to inform how DadCircles can be 'scaled locally', what works or doesn't work to form and activate Dad groups, enable us to get 'votes of confidence' for other regions i.e. where to target next.

AI Community Moderation: Using Gemini to help moderate local dad circles to keep them supportive and safe. This range from 1:1 messaging or email prompts to individual group members and group messages from the AI assistant to improve "matched people to active group" conversion rates. Currently, once a group is matched, an introduction message is sent with some light touch follow up. Localised suggestions or recommendations tailored to the individuals or group would be a powerful tool

Smoother onboarding: Expanding the onboarding experience to introduce a "AI voice" that onboards individuals. People have different preferences when it comes to communication. We would want to test different mediums and how they perform e.g. email, messaging, calls.

LONG A bigger solution. A bigger market: viewing Dadcircles as a "group facilitator program" could translate to other world social problems. There is a world where the learnings and mechanics we build can be expanded to other social groups. This type of 'campaign' could evolve into a new 'email campaign' format for other groups, communities and businesses to deploy.

Early Traction

  • 58 sign ups from 1x post on a local Ann Arbor forum resulting in a request to connect from a well known non-profit "Mamas Network Group" in the local Ann Arbor area.
