Company profile

researched Aug 2026

Champ (trychamp.co) markets an "AI SDR" product that automates the top of the B2B sales funnel. According to the company website, the system identifies interested leads, reaches out to decision makers by email, handles meeting logistics such as time zones and availability, and books meetings directly on the user's calendar. The stated aim is to leave human sales staff to focus on closing deals while the AI agent continuously develops sales-qualified leads to populate the pipeline [0][1].

The product's core capabilities, as described by the company, are deep research (scanning hundreds of pages about a prospect's business in under a second), creative writing of personalized outreach messaging, and repetitive execution of daily outbound tasks. Emails are said to be built around discovered pain points, prospect-appropriate terminology, subject lines and call-to-action variations, with intelligent follow-up and ongoing nurture [0][1].

Champ is listed in the Y Combinator company directory under the Summer 2022 batch, categorized as Artificial Intelligence, B2B and Sales, and based in San Francisco. The YC profile lists Matt Sun and Daniel Wasserlauf as founders (shown as former founders on that page). The same profile carries a company launch for Mocke (mocke.co), a standalone cold email AI agent that generates campaign ideas, email templates with embedded research prompts, and per-lead personalized messages [2].

Business model

Champ sells an AI-driven sales development capability to sales organizations; the website's calls to action are "Get started today" and "See a demo," indicating a demo-led sales motion. Pricing terms are not disclosed in the available sources [0][1]. The related Mocke product is described in the YC launch post as free to use with no sign-up required [2].

Traction

The website claims aggregate outbound performance of a 99.5% delivery rate, 68% open rate and 8% reply rate, and states that each AI SDR saves 40 hours per week of outbound work; it also references being "trusted by leading companies" without naming them. No customer names, revenue or user counts are disclosed in the available sources [0][1]. The Mocke launch post refers to beta users but gives no numbers [2].

Latest developments

The most recent development documented in the sources is the launch of Mocke, an AI agent for cold email that produces campaign ideas, prompt-embedded email templates and per-lead researched messaging in about 60 seconds from a user's website URL [2].

▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies

Market position

Champ positions its AI SDR as an alternative to manual outbound work and to general-purpose chatbots, explicitly contrasting itself with a "clunky ChatGPT experience." The Mocke launch post argues that generic AI-written cold email is now commoditized and that other AI sales tools produce shallow personalization based on LinkedIn activity such as promotions or recent posts, which recipients recognize; Champ frames per-lead deep research and relevance as the differentiator [0][1][2].

Stated differentiators are per-lead deep research feeding the message content rather than surface-level personalization tokens, prompt-embedded email templates that let users choose between full delegation to the AI and finer manual control, and end-to-end coverage from campaign ideation through outreach, follow-up and meeting scheduling [0][1][2].

Technology

The product is described as an AI agent for sales development. Advertised technical behaviors include automated deep research across hundreds of pages of information about a prospect's business in under one second, generation of personalized email copy (subject lines, paragraphs, calls to action), automated follow-up sequences, and scheduling logic that resolves time zones and availability [0][1]. The Mocke launch post describes a workflow in which the agent infers an ideal customer profile and pain points from a website, produces email templates containing bracketed prompts that instruct the model what to research and personalize per lead, and then executes lead-by-lead research and message generation over an uploaded lead list [2].

Go-to-market

Self-serve sign-up and demo requests from the company website, plus product-led distribution of the free Mocke cold email tool, which requires no account and is promoted through a Y Combinator launch post inviting users to try it and give feedback [0][1][2].

B2B sales teams and individual sales professionals responsible for outbound prospecting; the messaging targets buyers who want booked meetings with decision makers who hold budget [0][1].

Geography

San Francisco, California, per the Y Combinator company profile [2].

History

The Y Combinator directory lists Champ in the Summer 2022 batch with an Active status and founders Matt Sun and Daniel Wasserlauf [2]. The company subsequently launched Mocke, a standalone cold email AI agent at mocke.co, announced in a YC company launch post authored by Matt Sun [2].

Risks & controversies

Performance figures on the company website (delivery, open and reply rates; 40 hours saved per week) are self-reported and unverified by third-party sources, and the "trusted by leading companies" claim is not accompanied by named customers [0][1]. Note also that several widely circulated news items about a "Champ AI" that raised $8.5 million led by Redpoint Ventures concern a different, similarly named San Francisco company (champ.ai, founded by Jagannath Putrevu, Ted Cheng and Peter Lin, building enterprise operations-workflow automation) and are not attributable to this company.
