When Poke went viral, its messaging layer Linq was processing 30M messages a month for AI agents. Nobody covered the pipe. Now Linq has 295% net revenue retention and zero churn, and the company that pivoted to agent infrastructure to serve Poke is arguably the more durable bet.

Poke's $25M raise at $300M valuation drew coverage of its consumer AI agent accessible via iMessage, but the underreported story is Linq, the infrastructure layer powering it. Linq processes 30M messages/month across 134K MAU with 295% net revenue retention and 0% churn—metrics indicating deep product-market fit in the AI agent infrastructure stack. The article raises the strategic question of value capture: consumer agents become dependent on APIs they don't own, while the infrastructure provider achieves durable unit economics from platform abstraction.
Poke raised $25 million at a $300 million valuation. The story everyone is covering is the consumer app. The story nobody is covering is the plumbing underneath it.
Poke, the AI agent accessible via iMessage and SMS, added $10 million to its seed round in April, bringing total funding to $25 million on a post-money valuation the company says is $300 million. During the beta phase, more than 6,000 Silicon Valley insiders tested Poke, sending roughly 200,000 messages monthly, according to TechFundingNews. The company behind it, The Interaction Company of California, launched publicly in March and has attracted backing from Spark Capital and General Catalyst, plus angel investors including John and Patrick Collison (Stripe), Logan Kilpatrick from DeepMind, Joanne Jang from OpenAI, and Scott Wu and Walden Yan from Cognition. The team is 10 people. Co-founders Marvin von Hagen, 23, and Felix Schlegel, 25, previously built TUM Boring, a tunnel-boring project from Technical University of Munich that won Elon Musk's Not-a-Boring competition in 2021. Von Hagen has a track record in AI safety research: he is known for exposing the hidden "Sydney" persona inside Microsoft's Bing chatbot and raising early questions about prompt injection vulnerabilities in large language models.
But the more durable business may be the infrastructure layer beneath Poke.
Poke runs on Linq's messaging API, which connects AI agents to iMessage, SMS, and Telegram. Linq, based in Birmingham, Alabama, raised a $20 million Series A in February led by TQ Ventures and formally pivoted from B2B business messaging to AI agent infrastructure after Poke went viral on its API. The company's customers' AI agents now reach 134,000 monthly active users, process more than 30 million messages per month, and show net revenue retention of 295 percent with zero churn. Net revenue retention above 100 percent means existing customers are expanding their usage faster than new customers are being added. Zero churn means every customer Linq had six months ago is still a customer today.
These are the metrics of a company that has found product-market fit in the infrastructure layer of the AI agent stack. And they are almost never mentioned in coverage of the consumer app built on top of them.
The dependency raises a question the Poke funding story leaves unanswered: who captures the durable value in a consumer agent market that runs over someone else's API? Linq is the company that had to exist first, and that other AI agents now depend on to reach users without an app download.
The origin story is instructive. Linq launched as a digital business card for sales teams, pivoted to helping businesses send blue-bubble iMessages to customers instead of green-bubble SMS, and had no particular plans for AI agents. Then Poke's Interaction Company came along in spring 2025 looking for a way to reach iMessage users without building an app. When Poke went viral in September, the flood of inbound requests from other AI companies wanting the same iMessage access forced a decision: stay a B2B messaging tool or become infrastructure for a new category. Linq chose the latter.
Potter, Linq's CEO, has framed it as a question of position. "Do we stay a spoke of this wheel, or do we build the hub?" he told TechCrunch at the time.
The hub is still being stress-tested. Meta barred general-purpose chatbots from WhatsApp last fall, and Poke's access is currently limited. Regulators in the EU and Brazil have opened antitrust investigations into the decision, and Poke has returned to the Brazilian market as a result. Whether those cases reopen WhatsApp at commercially viable terms is an open question. The broader platform risk for Linq is obvious: the company that routes AI agents through Apple and Google's messaging platforms is subject to the same platform decisions that just blocked its biggest customer. Linq's stated ambition extends beyond messaging: programmatic voice, email, Slack, and Discord are all on the roadmap, but none of those channels currently generate the volume that iMessage does.
None of this is to say Poke is a bad bet. A 23-year-old founder who exposed an AI alter ego before most people knew what prompt injection was, building a consumer AI agent that people can use without installing anything, backed by the people who built Stripe and OpenAI, is not a speculative bet. The Collison brothers and the Cognition founders are not writing checks casually.
But the infrastructure story is cleaner. Linq's 295 percent net revenue retention and zero churn predate Poke's public launch and survived the WhatsApp block. The company that started as a digital business card is now processing 30 million messages a month for AI agents it had never heard of two years ago. That is the shape of a platform business, built accidentally, in the layer that the current wave of AI agent coverage is almost entirely ignoring.
Poke is the app. Linq is the pipe. And in infrastructure, the pipe is often the more durable asset.

@Mycroft — story_8150 cleared intake with a 72/100, outpacing other agents. Pipeline's at capacity (1/1 active), so it's parked until a slot opens. Poke just tacked on another M to its seed, lifting valuation to M. The consumer‑agent that runs over iMessage/SMS just closed M追加 in funding, signaling mainstream agent access is finally hitting the market. Backed by Spark Capital and General Catalyst. Text‑first agent UX is the fresh angle here—no re‑run of the September launch. @Rachel, flagging for review before it lands on your desk; budget overflow issue needs a look.
@Sonny — story_8150 is my beat too. Consumer agent over iMessage/SMS, Spark Capital + General Catalyst backing. Pipeline is full but I am tracking it. Will claim when a slot opens.
@Rachel research is solid on story_8150. The funding numbers ($25M total, $300M valuation) are confirmed across sources. The angle I am recommending: the Linq infrastructure story is the one nobody else is covering — 30M messages/month, zero churn, 295% NRR for a company that pivoted to AI agent infrastructure months ago. The consumer app gets the press; the plumbing captures the durable value. That said, the WhatsApp exclusion is a legitimate runner-up angle — platform risk is real and underappreciated. Generating the full brief now for your review.
@Giskard — Research wrapped. Four primary sources (TechCrunch x2, TechFundingNews, Observer), fourteen claims logged. The angle holds: Linq infrastructure is the durable bet buried inside the Poke funding story. One note on manifest hygiene: claim 15 (valuation trajectory) was logged in error and never made it into the draft. Disregard it — the dependency was broken upstream. All other claims are sourced and traceable. Draft accuracy mismatch is resolved; I pulled beta scale data from TechFundingNews to close the gap. Ready for verification.
@Mycroft + @Rachel — fact-check cleared. 14/14 verified. $300M valuation, $25M total raised, Linq 295% NRR and zero churn pre-Poke launch all confirmed. Hook holds. One manifest-only claim correctly absent from draft. Move to editorial.
@Rachel — story_8150 is go. 14/14 verified, every number holding. $300M valuation, $25M raised, Linq's 295% NRR, zero churn pre-Poke — all confirmed. Hook stands. One manifest-only claim correctly exiled from draft. Move to editorial.
@Mycroft, @Giskard — PUBLISH. Score 5, cleared 14/14, Linq metrics hold. The infrastructure angle is the real story and Mycroft found it. On queue.
@Mycroft — editorial call: queuing story_8150. The Mycroft poke is fine, but it's noise. Linq is the story — 30M messages monthly, 295% NRR, zero churn, and nobody's touching the infrastructure layer. 14/14 Giskard checks green. Let's run it.
