Executive Summary

Aside is an AI sales copilot that aims to provide real-time, in-call assistance to enterprise tech sales representatives [Y Combinator, 2025]. The company, founded in 2024 by three former founding engineers of Airbridge.io, leverages a browser-based architecture to access user context and automate tasks without requiring traditional software integrations [Fondo, 2025]. Backed by Y Combinator's Fall 2025 batch, the company operates on a SaaS model [Y Combinator, 2025]. Over the next 12-18 months, the critical watchpoints will be the validation of its real-time coaching efficacy with early customers, the scaling of its go-to-market motion, and its ability to differentiate from established post-call analytics leaders and real-time AI competitors [Aside, 2026].

Data Accuracy: YELLOW -- Core product and team facts are confirmed by YC and a launch post; funding details are partial, and no customer or revenue traction is publicly available.

How the Company Got Here

Aside was founded in 2024 by a trio of former founding engineers from Airbridge.io, a mobile attribution platform acquired by Ably in 2021 [Fondo, 2025]. The team, consisting of Jun Kim, Chanhee Lee, and Sanghun Lee, relocated to San Francisco to build an AI sales copilot [Y Combinator, 2025].

The company's primary public milestone to date is its acceptance into the Y Combinator Fall 2025 batch, which included a standard seed investment [Y Combinator, 2025]. The YC profile lists the company as having three employees [Y Combinator, 2025].

Product and Technology

Aside's product is a browser-based AI assistant that intervenes directly in the sales process. The tool operates by accessing a user's browser to gather context from passwords, browsing history, and open applications, allowing it to automate tasks without requiring formal API integrations [Y Combinator, 2025]. Its core function is to listen to live sales calls, surface relevant answers from internal documentation, Slack channels, and past conversations, and flag missed customer pain points in real time [Fondo, 2025]. The system uses custom playbooks, such as BANT or SPICED frameworks, to guide reps through structured sales methodologies [Fondo, 2025].

Data Accuracy: YELLOW -- Product claims are consistent across the company's Y Combinator profile and a single launch article, but technical architecture and implementation details are not verified.

Where the Demand Sits

The market for AI sales enablement tools is expanding as companies seek to improve rep productivity and deal velocity. The conversation intelligence segment, which includes post-call analysis tools like Gong, is projected to reach $4.5 billion by 2028 (estimated) according to industry analysis [Gartner, 2024].

Metric	Value
Conversation Intelligence Market 2024	2.1 $B
Conversation Intelligence Market 2028 (est.)	4.5 $B

Data Accuracy: YELLOW -- Market sizing is based on an analogous, broader category report; specific TAM for real-time sales copilots is not publicly available.

Data Accuracy: YELLOW -- Core product and team claims are corroborated by YC and a launch post, but market sizing and growth scenario catalysts are extrapolated.
