Software development services

Four software practices.
One delivery team.

Grootcore offers end-to-end software development services across four practices: web development, mobile app development, AI agent development, and AI automation. Hire a single practice, or use us as the engineering function for everything you're shipping this year — the team, process, and delivery culture are the same.

01 / Practice

Custom website & web app development

Grootcore's web development services cover marketing websites, SaaS products, customer dashboards, and internal admin tools. Every web project ships on a typed React and Next.js stack — engineered for performance budgets, an SEO surface your marketing team can own, and a content workflow that doesn't route every typo through engineering.

Mobile app development — iOS & Android

Our mobile app development services cover native iOS (Swift / SwiftUI), native Android (Kotlin / Jetpack Compose), and cross-platform React Native and Flutter — picked on your brief, not on team preference. We treat App Store and Play Store review as a deadline, ship behind feature flags, and budget for crash-free sessions from day one.

AI agent development for production

Most AI agent projects fail at evaluation, not modelling. Grootcore's AI agent development services cover the full stack — orchestration, retrieval-augmented generation, tool use, guardrails, and a custom evaluation harness that catches quality regressions before customers do. We've shipped customer-facing support agents, sales-assist agents, and internal operations copilots.

AI automation across your tech stack

Grootcore's AI automation services replace recurring busywork — voice AI callers, document intake, CRM enrichment, finance reconciliation, support triage, approval routing. We deploy AI voice agents on Retell AI and Vapi, build outbound and inbound AI callers, and ship Go High Level (GHL) funnels and sub-account automations alongside custom backend pipelines. We map the workflow, design the failure modes, instrument observability, and integrate with the tools your team already uses.

Software development engagement models

Three ways to
hire Grootcore.

Three engagement shapes, picked on the problem. We'll tell you which one fits your software project in the first conversation.

01

Fixed-scope project

A defined deliverable on a defined date, priced per milestone. Best for greenfield software builds, MVPs, and replatforming.

02

Monthly retainer

A senior software team-of-three on your roadmap. Best for ongoing product work, AI evaluation cycles, and platform investment.

03

Staff augmentation

Senior Grootcore engineers embedded in your repos, your standups, and your on-call. Best for in-house teams that need senior bandwidth fast.
