About
PartnerHQ is a San Francisco, California-based B2B warm introduction marketplace — backed with $500,000 in seed funding from Y Combinator (Winter 2024 cohort), 1Indicator, Rebel Fund, Sancus Ventures, and Maiora Ventures — connecting B2B companies seeking introductions to decision-makers with professional network connectors who earn paid bounties ($500 average per introduction) for facilitating warm introductions that replace cold outreach. Founded in 2023 by Stanford graduates Stan Liu and Katherine Wang, PartnerHQ launched in February 2024 and within its first year signed hundreds of paying companies with 97% of growth coming from inbound and word-of-mouth channels. The platform's founding thesis was validated through the founders' prior experience managing partnerships at Brackets For Good, a nonprofit that managed 150+ sponsors and 750 organizations across 12 markets raising $12 million for charities. PartnerHQ operates with a small founding team and builds what the founders describe as a professional relationship graph to match buyer needs with connector network access.
AI go-to-market platform for solar, roofing, and HVAC installers automating property design and proposals; near $1M ARR in 9 months with $2.5M seed from YC and noa PropTech.
About
Aether is an AI-powered go-to-market platform for home services installers — specifically solar, roofing, HVAC, and landscaping companies — that automates the technical sales workflow from property data gathering through design generation to proposal creation. Founded in 2024 and a Y Combinator graduate, Aether raised $2.5 million in seed funding led by noa (formerly A/O PropTech), Y Combinator, and others, reaching nearly $1 million in ARR within nine months of launch.\n\nAether's platform uses computer vision to analyze property data (aerial imagery, satellite photos, roof measurements) and automatically generate installation designs and proposals — replacing the hours that sales engineers and field estimators previously spent measuring properties, creating designs, and building proposals manually. For a solar company, Aether pulls satellite imagery, calculates roof usable area, generates a solar array layout, and produces a professional proposal with projected energy output and ROI in minutes rather than days. This speed-to-proposal gives home services companies a competitive advantage in a market where faster follow-up significantly improves close rates.\n\nIn 2025, Aether competes in the home services sales automation market with Aurora Solar (solar design software), EagleView (aerial measurement), Hover (3D property measurement for roofing), and Scoop Solar for automated property assessment and proposal generation. The residential solar and roofing markets are particularly attractive because the high transaction values ($15,000-100,000 per installation) justify significant investment in sales efficiency tools. Near $1 million ARR within 9 months of launch demonstrates rapid product-market fit. The 2025 strategy focuses on deepening the automation for each vertical (solar, roofing, HVAC have different design requirements), growing the installer customer base through contractor association partnerships, and adding AI-powered follow-up and lead nurturing features.
