Chert

iMessage infrastructure for trusted communication at scale

Spring 2026ActiveB2BArtificial IntelligenceSaaSAPICustomer SupportConversational AISan Francisco, CA, USA
Chert provides the infrastructure for businesses to automate conversations over iMessage. We’re already working with B2C startups, customer experience teams, and sales teams to reach end users through trusted and conversational messaging.

Verdict

Medium Signal
Market Opportunity
Business messaging is a real and large market (B2B SaaS, CPaaS players like Twilio operate in the billions). iMessage specifically targets high-trust consumer-facing channels, which is a genuine pain point for B2C companies. However, the ICP is loosely defined across 'B2C startups, CX teams, and sales teams' and iMessage as a platform carries significant Apple policy risk that could constrain the TAM.
Low Signal
Founder Signal
Both founders appear to be recent or near-recent grads with limited professional work experience. Ian studied Math/Econ at NYU with fast algorithm research at Courant and hackathon wins — no industry roles cited. Gary studied CS/Business at Penn and spent 'the past year' on ML research and chip design — no full-time engineering or startup roles. LinkedIn profiles unavailable, which limits deeper assessment. Neither founder has a prior exit or senior industry role.
Low Signal
Competition
No competitor data was found in research, but the space is well-populated: Twilio, Bandwidth, and Sinch dominate SMS/messaging infrastructure. iMessage-specific automation is legally and technically constrained by Apple — Apple does not offer a public iMessage API, meaning Chert likely uses workarounds (e.g., Mac hardware farms) that are fragile and potentially ToS-violating. This is a significant structural risk, not a moat.
Medium Signal
Product
Claims to be 'already working with B2C startups, customer experience teams, and sales teams' which suggests some live customers, but no named logos, revenue figures, or usage metrics are provided. API-based iMessage infrastructure is a real product concept, but no demo, docs, or pricing page evidence is available from the data provided.
OverallC Tier

The core technical premise is risky: Apple does not expose a public iMessage API, so any iMessage automation infrastructure is almost certainly built on brittle workarounds that Apple could shut down at any time — this is a fundamental platform risk, not a differentiator. The founders are talented but appear to be fresh grads with no industry engineering or startup operating experience, and LinkedIn data is unavailable to verify further. There's a vague claim of early customers but no hard traction signals. The messaging infrastructure market is huge but dominated by entrenched players, and the iMessage niche is more a legal/technical minefield than a defensible wedge. Would need to see evidence of Apple compliance, named customers, and revenue to reconsider.

My name is Ian. I'm building Chert, the infrastructure that lets teams send, receive, and automate iMessage conversations through our APIs. Before this, I studied Math and Econ at NYU, did fast algorithm research at Courant, and won 8 hackathons along the way. Outside of work, I run triathlons, play Go, and still hit random hackathons with Gary for fun. fun fact: I've lived in a total of 16 cities in 20 years of my life.

Hi, I'm Gary, co-founder and CEO at Chert. We're building the infrastructure that lets teams send, receive, and automate iMessage conversations through APIs. Before moving to SF last month, I studied CS and Business at Penn and spent the past year researching ML model architectures, designing neuromorphic chips, and building projects with my co-founder Ian. Outside of this, I like flying planes, running marathons, and reading!
