AI agents inside iMessage with Photon.
We build AI agents that live inside iMessage using Photon's Spectrum framework — no app download, no website, just the conversation your customers already trust.

The short answer
Photon's Spectrum framework gives agents a way into the messaging interfaces people already use every day — iMessage above all. There is no official Apple iMessage bot API, so most teams choose between sales-oriented APIs, fragile Mac-based bridges, or Photon's managed infrastructure. Photon handles the persistent gRPC connection, message routing, and SMS/RCS fallback so the agent never needs to touch a Mac or maintain a webhook.
Bolder uses Photon when a client wants an agent to live where their customers already text — not in a new app they have to download. The Spectrum SDK is open source and TypeScript-only, deploys to iMessage, WhatsApp, Telegram, Slack, and Discord from one codebase, and supports sending full agentic mini apps (menus, booking flows, mini games) directly inside an iMessage thread.
The conversations that bring iMessage agent projects to Bolder.
Real scenarios that bring Photon-powered iMessage agents to Bolder. If one sounds familiar, we've built it before.
iMessage Concierge & Booking Agent
An agent that takes reservations, answers questions, and confirms bookings entirely inside iMessage — no app download required.
AI Matchmaking & Community Agents
Agents that connect users, run conversations, and manage group chats natively inside iMessage at scale.
In-Chat Mini App Commerce
Send a menu, a checkout flow, or a mini game directly inside an iMessage thread — no website or app needed.
Customer Support Agents on iMessage
Support agents that answer, escalate, and resolve tickets where customers already text — with SMS/RCS fallback built in.
Voice-to-Text Continuity Agents
Agents that move seamlessly between a phone call and an iMessage thread, continuing the same conversation across channels.
Multi-Channel Agent Deployment
Write agent logic once and deploy across iMessage, WhatsApp, Telegram, and SMS from a single Spectrum integration.
Photon expertise that goes beyond the API call.
We don't just wire up an API call. We understand gRPC stream supervision, Spectrum's tool schemas, and the fallback logic that keeps an agent reachable when iMessage delivery fails.
Spectrum SDK
Open-source TypeScript framework connecting agents to messaging platforms.
Agentic Mini Apps
Send interactive UI — menus, mini games, booking flows — directly inside iMessage.
Unified Channel Routing
Single agent codebase reaches iMessage, WhatsApp, Telegram, Slack, and Discord.
Omni Voice Integration
Agent can text during a call and call from a thread using the Omni plugin.
Your next app shouldn't take 6 months

No Mac. No webhook. Just a persistent stream.
Spectrum runs as a persistent gRPC stream. No webhook, no public URL, no Mac relay required to keep an agent live.
One agent, every channel that matters.
Write agent logic once and reach iMessage, WhatsApp, Telegram, Slack, and Discord from a single Spectrum integration.
An agent can text during a call and call from a thread, using the Omni plugin to connect to SIP platforms like LiveKit and Retell.

Bolder Apps is a Miami-headquartered mobile and web app development agency, founded in 2019. We partner with startups and businesses worldwide, combining US-based leadership with a distributed engineering team.
Typically 8–20 weeks depending on project scope and complexity. Bolder Apps moves faster than most agencies — proposals are turned around in 1–2 days versus the industry norm of 1–2 weeks.
Bolder Apps serves a wide range: FinTech, Healthcare, Lifestyle, Retail, Ecommerce, Social Media, On-Demand, and Professional Services.
Headquartered at 78 SW 7th, Miami, FL 33130, USA. The engineering team is distributed globally.
At Bolder Apps, we utilize a variety of programming languages and frameworks to best suit your project’s needs. For cross-platform development, we use Flutter or Flutterflow, which allows us to efficiently support web, Android, and iOS with a single codebase—ideal for projects with tight budgets. For native applications, we employ Swift for iOS and Kotlin for Android applications.
For web applications, we combine frontend layout frameworks like Ant Design, or Material Design with React. On the backend, we typically use Laravel or Yii2 for monolithic projects, and Node.js for serverless architectures.
Additionally, we can support various technologies, including Microsoft Azure, Google Cloud, Firebase, Amazon Web Services (AWS), React Native, Docker, NGINX, Apache, and more. This diverse skill set enables us to deliver robust and scalable solutions tailored to your specific requirements.
Mobile app development typically ranges from $30K to $250K+ depending on complexity, platform, and features. Bolder Apps uses scope-based pricing — no hourly billing — so your budget is defined before development begins.
We work on fixed-scope pricing, not hourly rates. This means you know exactly what you're getting and what it costs before we write a single line of code.
Every project includes strategy, UI/UX design, development, QA testing, App Store submission, and 4 weeks of post-launch maintenance. No hidden fees.
Projects typically start from $30K. For early-stage startups, a Paid Discovery session is a cost-effective way to validate your idea and build a roadmap before committing to full development.
You connect directly with a Product Consultant — no salespeople. Within 1–2 days you receive a tailored proposal. From there: discovery → strategy → design → development → launch.
A structured engagement where we deeply analyze your product goals, user needs, and technical requirements — producing a concrete roadmap before any development begins.
Yes. We specialize in taking early-stage ideas from concept to a shippable product, fast. Many of our clients launch their first version within 10 weeks.
You work directly with a senior Product Consultant throughout the entire project — not a rotating cast of account managers or junior staff.
iOS, Android, and web. We build native apps using Swift and Kotlin, or cross-platform using Flutter — supporting all three from a single codebase when budget efficiency matters.
Yes. We integrate AI features including LLMs, recommendation engines, and automation workflows. We're an official OpenAI partner with direct access to API credits for qualifying projects.
Yes. We offer Code Audit services to review your existing architecture before recommending whether to build on top of it or start fresh.
We implement data encryption, secure coding practices, regular security audits, and follow platform-specific security guidelines for both App Store and Google Play.
