Hightouch: Revolutionizing Personalized Marketing With The First Agentic Marketer

Hightouch recently raised $80M in Series C funding at a $1.2B valuation to bring AI Decisioning to marketers. While marketers have long struggled to send the right message at the right time, Hightouch has created a solution that uses AI agents to deliver personalized experiences across multiple channels, like email, push notifications, and ads. Their AI agents optimize each customer’s journey, automatically running experiments and providing insights into what works for different groups of customers. Today, they serve leading brands like Autotrader, Spotify, Cars.com, Grammarly, and PetSmart. YC Partner Gustaf Alstromer recently sat down with the Hightouch founders to talk about how they got here, their founding story, and the kind of company they are building.

📖 CHAPTERS

1. 1

   Hightouch today: outcome-driven, agentic personalized marketing

   Gustaf introduces Hightouch and frames the company’s current mission: an “agentic marketer” that helps teams achieve specific marketing outcomes. The founders describe how an AI agent can personalize campaigns at the level of an individual customer, using both online and offline activity data.

2. 2

   Formation story: quarantine house, pivot hell, and deciding to merge

   The founders recount how, during early COVID quarantine, they were all pivoting separate ideas while living in the same house. Instead of anchoring on a single thesis, they bet on the team’s ability to persist and figure it out together.

3. 3

   Finding the wedge: why Reverse ETL emerged

   After exploring other directions post-travel collapse, they noticed a consistent customer pain: business teams couldn’t access warehouse data easily. As warehouses like Snowflake/BigQuery grew, “Reverse ETL” became the way to move data from the warehouse into SaaS tools used by marketing and sales.

4. 4

   Getting first customers: network intros, communities, and selling while building

   They landed early customers (including Retool) through a mix of network introductions and proactive outreach in online communities. They effectively sold the product as they were building it—sometimes in extremely scrappy ways—to ensure it worked end-to-end for paying users.

5. 5

   Signals of product-market fit: broad demand and true self-serve signup

   Two moments stood out: realizing diverse global industries shared the same use case, and later seeing multiple customers onboard without talking to the team. That “pull” motion (SEO/content-driven inbound) validated the category and the go-to-market they believed in at the time.

6. 6

   Three phases of the company: category creation → business users → AI reinvention

   They describe Hightouch’s evolution as three major phases. First, they created the Reverse ETL category and gained many inbound logos; next, they shifted toward business-user workflows and verticalized into marketing; later, they competed in the CDP space and chose to innovate again with an agentic marketer.

7. 7

   “Innovate or die”: why they keep rethinking the product

   Even during strong growth, they repeatedly questioned whether the current product was enough for the long-term market. Their view is that marketing/data is inherently competitive and obvious; to survive, they must proactively find the next disruptive tranche rather than wait for it.

8. 8

   Early hiring philosophy: high-aptitude builders from personal networks

   In the earliest days, they leaned on personal connections and hired people who could grind, learn, and adapt—often before they had a formal interview process. They optimized for “startup-ready” traits: speed, resilience, and the ability to figure things out in ambiguity.

9. 9

   The Hightouch interview: one 90-minute “core interview” focused on thinking

   Their engineering interview process is intentionally lightweight and high-signal: a single 90-minute, no-prep, architecture/problem-solving session. It prioritizes communication, system thinking, and product/business judgment over live coding, and candidates tend to respond positively to the simplicity.

10. 10

    Team scale and what they sell candidates on: ownership, impact, and agency

    They share current headcount and how they attract talent despite competing opportunities. The pitch centers on high ownership and being rewarded for impact—especially for people who can identify what matters most and execute without being micromanaged.

11. 11

    Founder motivation, co-founder dynamics, and handling stress at scale

    The founders discuss what keeps them going: technical challenge, responsibility to employees, and ambition to build a massive business. They also explain why multiple co-founders matter—someone is always in a low moment, and the others keep momentum—while repeated crises eventually desensitize founders as they learn quickly and move on.

12. 12

    Staying low-profile, who they’re hiring, and where they work

    Despite reaching large-company scale, they note Hightouch has remained relatively low-profile. They close by describing the type of people they need for the next AI/decisioning wave, the breadth of roles they’re hiring for, and their in-person hubs in SF and New York.
