CONVERSION, SAN FRANCISCO - The brand mark of an AI-native platform betting that good software, not bigger RevOps teams, wins the campaign.
The Dispatch

It started as a tool they built for themselves.

It is the middle of a workday in San Francisco, and somewhere a marketing operations lead is doing what marketing operations leads do: fighting their software. Exporting a list. Re-importing it. Patching one tool to another with a brittle integration that breaks before lunch. Conversion exists because its founders watched that scene play out - in their own company first - and decided the tool was the problem, not the person using it.

Neil Tewari and James Jiao were roommates at UC Berkeley with a shared, slightly inconvenient conviction: they wanted to start a company more than they wanted a degree. They tried a few things first. NFT experiences inside Roblox. Billboards in Minecraft. An AI website builder. None of them stuck, but all of them needed marketing - and that is where the real problem found them.

To run their own growth, they signed up for HubSpot and started building extra automation on top of it. The bolt-ons worked better than the thing they were bolted onto. "It was originally for us," Tewari has said. The pivot was less a strategy than an admission: the tool they had built as scaffolding was more useful than the products it was supposed to support.

You shouldn't need a team of RevOps specialists to send a great campaign.

So they did the unglamorous work. One hundred and sixty interviews with marketing VPs at companies between 50 and 500 employees. The same complaint, over and over: more than half their time went to wrestling software instead of doing marketing. A family friend - the first believer, recruited during a car ride home from school - opened doors that became a $2M seed round. Tewari and Jiao dropped out at 19 and went all in.

What they built is an AI-native marketing automation platform. In plainer terms: a system that pulls together product data and CRM data, watches for buying signals, and lets a marketer send the right message at the right moment - without code, without a specialist, without the export-import shuffle. The pitch is not that AI writes your emails. It is that the whole machine, finally, knows what it is doing.

What It Does

Five parts of one growth engine.

01

Drag-and-Drop Email

A brand-compliant builder so marketers ship campaigns without code or a design queue.

02

Magic Blocks

Personalization that pulls product-usage and firmographic data straight into the message.

03

Real-Time CRM Sync

Two-way syncing keeps contact, product and CRM data live across the whole stack.

04

No-Code Workflows

A visual builder for multi-step journeys triggered by behavior and intent.

05

Dynamic Segmentation

Audiences that rebuild themselves in real time from combined product and CRM signals.

The People

Two roommates, one bet.

Co-Founder & CEO

Neil Tewari

Caught watching a TechCrunch Disrupt livestream in high school class and sent to the principal's office. Studied EECS at Berkeley, then left to build the company he kept daydreaming about.

Co-Founder & CTO

James Jiao

Tewari's Berkeley roommate and technical co-founder. Together they cycled through a handful of products before the marketing tool they built for themselves became the business.

The Money

From $1M to nearly $10M ARR.

Revenue, by year - approximate, from public reporting. The Series A added $28M on top, bringing total raised to roughly $30M.

The Close

Back to that workday in San Francisco.

Picture the marketing operations lead again. Same desk, same Tuesday. But the export-import shuffle is gone. The product data and the CRM data sit in one place. A buying signal trips, a workflow fires, a personalized email goes out - and nobody had to file a ticket with RevOps to make it happen. That is the whole point of Conversion, and it is a quietly radical one: the unglamorous middle of marketing should just work.

Conversion is not promising to replace the marketer. It is trying to give that person their afternoon back. Whether it can keep taking share from HubSpot, Marketo and Pardot while fending off the AI-native crowd is the open question of its next chapter. For now, the scene it set out to fix looks a little different - and 4,000 companies have decided that difference is worth switching for.
