B2B API — Child Development Platforms

The activity engine
your platform is missing.

Two inputs: age in months and zip code. Three safe, developmentally appropriate activities, embedded directly into your product via API. Your team ships a smarter feature without building anything from scratch.

of brain development happens before age 5. The tools built to support that window have not kept up.

2 inputs

Age in months and zip code. Everything the engine needs to make a precise, context-aware decision.

3 outputs

Three activities, precise, safe, and right for this child, right now.

How CubbiAI thinks

Four layers of logic. Every single request.

Age, context, regulation state, and safety constraints, applied automatically before a single activity surfaces.

Age in months, not broad ranges.

Most platforms group children into wide age buckets. CubbiAI knows that 14 months and 22 months are fundamentally different developmental stages.

Every activity maps to exact developmental windows, so the output is right for the specific child, not a child somewhere in the same age range.

Age Precision Engine
14 months
Fine motor + early language focus
22 months
Symbolic play + gross motor expansion
30 months
Imaginative play + social readiness

Stimulation or regulation: the engine decides.

A child who needs to wind down gets different activities than one who needs engagement. CubbiAI factors regulation state into every output automatically. It is built into the engine, not bolted on by your team.

Regulation Logic
High energy state
→ Gross motor, outdoor, movement activities
Calm / wind-down
→ Sensory, quiet, fine motor activities
Transitional moment
→ Routine-based, predictable activities

Context-aware. Always.

Time of day and real-time weather both factor into every output. A rainy afternoon produces different activities than a sunny morning, automatically. The zip code is the only input the engine needs to get there.

Context Engine
Sunny, 74°F, 10am
→ Outdoor, movement-forward activities
Rainy, 48°F, 3pm
→ Indoor sensory and creative activities
Evening, any weather
→ Calming, wind-down activities

Safety enforced at every output.

Hard safety constraints are built into the engine, not reviewed after the fact. Nothing developmentally inappropriate or physically unsafe ever surfaces.

Activity logic has been reviewed by a licensed pediatric physician. Your platform inherits those guarantees without any additional work.

Safety Constraints
Choking hazard rules
Enforced by exact age in months
Physical complexity limits
Matched to motor development stage
Supervision requirements
Flagged per activity output automatically
What the engine already knows

Everything your team needs, already built in.

Your team ships a premium feature without building a single line of decision logic.

01

Developmental milestones

Activities mapped to fine motor, gross motor, language, cognitive, and social milestones, by exact age in months.

02

Real-time weather

Live weather data from the child's zip code routes indoor vs outdoor activities automatically on every request.

03

Wake windows

Time-of-day logic ensures activities align with typical toddler energy cycles: morning, afternoon, and evening.

04

Safety constraints

Choking hazards, physical complexity, and supervision flags, enforced at every output, reviewed by a pediatric physician.

05

No-repeat logic

The engine tracks prior suggestions and avoids repetition, keeping outputs fresh across every session.

06

Location context

Zip code provides regional and seasonal context, one input that powers weather, climate, and local relevance.

Medical validation

Activity logic reviewed by a licensed pediatric physician.

Every activity in CubbiAI's engine, and every safety constraint, has been reviewed and validated by a board-certified pediatrician specializing in early childhood development.

This is not a content library curated by generalists. It is a decision system built with clinical precision, so platforms that embed CubbiAI can stand behind every output with full confidence.

Integration

How CubbiAI fits into your platform.

Drop it into your existing product. Two inputs in, three outputs out. Your existing product flow stays intact.

Embedded activity engine

Your platform. Our decision layer.

CubbiAI embeds directly into your existing product flow. The engine runs quietly in the background and surfaces three structured outputs exactly where your users need them.

CubbiAI Output, 22 months · Menlo Park CA
01
Fill a small bin with dry pasta and cups. Scoop, pour, and transfer for fine motor practice.

02
Set up a simple obstacle course with couch cushions for climbing and crawling.
Language
03
Crayons and large paper. Name colors as they draw for language and creativity.
Cognitive
Simple by design

Two inputs. That is everything.

If your platform already stores the child's age and location, integration is seamless. If not, both are trivial to collect. Your team ships a premium feature without rebuilding anything from scratch.

About CubbiAI

Built from the inside out.

CubbiAI did not start with a market analysis. It started with a founder who lived the problem and could not find the tool that should have existed.

The origin

The problem was not effort. It was the tools.

CubbiAI was founded by an entrepreneur who left her career to go all-in on her daughter's development. She understood the science. She was hands-on, intentional, and genuinely creative.

And she still hit the wall. Every single day.

Not because she was not trying. Because no tool was built to answer the most loaded question in parenting: what should I do with my child right now?

The internet gives you everything except clarity. That gap is what CubbiAI was built to close. Not for one parent, but embedded inside the platforms that already serve millions of them.

"I had every resource available. I still did not know what to do with my daughter at 2pm on a rainy Tuesday. That is not a parenting failure. That is a product gap."
Founder, CubbiAI
Our perspective

The problem is not a lack of information.

Parents have more access to childcare guidance than any previous generation. Articles, tip libraries, curated lists. The volume is enormous and still growing.

None of it is built for the actual moment. It is broad by design, because broad is the only way to serve everyone at once. Which means it is precisely right for no one.

More content does not lead to better decisions. Structure does. That is what CubbiAI was built to be.

What makes CubbiAI different

Precision over volume.

Every other tool gives you more content, more options, more lists. CubbiAI gives you three, precise, contextual, and right for the moment.

Every other tool

Gives you more.

Thousands of activities. Broad age ranges. Generic lists that require parents to filter, interpret, and decide, adding friction to a moment that already demands too much.

CubbiAI

Gives you three.

Two inputs. One structured decision. Three activities, precise to the child's exact age in months, the time of day, the current weather, and the moment. Nothing more.

The market

Built for consumers.

Every major player sells directly to parents. The infrastructure layer, an embeddable engine that platforms can drop into their existing products, has not existed until now.

CubbiAI

Built for platforms.

We do not compete with your product. We make it smarter. Two inputs via API, three outputs returned. Your team ships a premium feature without building anything from scratch.

Your platform. Smarter.

Age in months and zip code in. Three precise activities out.

How we use data

The inputs we receive are used solely to generate activity recommendations. We may log anonymized API requests for performance monitoring and engine improvement. We do not sell, rent, or share data with third parties.

Contact form data

If you fill out our contact form, we collect your name, work email, and company name. This information is used only to respond to your inquiry. We do not add you to marketing lists without your explicit consent.

Data retention

Anonymized API logs are retained for up to 90 days for performance analysis. Contact form submissions are retained until your inquiry is resolved.

Children's privacy

CubbiAI is a B2B service and does not interact directly with children or collect any data from children. Our API receives only anonymous inputs provided by platform operators.
