About
TaxGPT is an AI-native tax preparation platform founded in 2023 and headquartered in San Francisco, built around the premise that the first full pass of tax work can be handled autonomously by AI rather than incrementally assisted. The company was founded to eliminate the bottlenecks and inefficiencies in tax workflow for both individual filers and accounting professionals. TaxGPT's core technology is an autonomous tax workflow agent that ingests documents, interprets tax law, and generates tax-ready outputs with minimal human review required.\n\nTaxGPT's platform addresses the full front-end of tax preparation: document ingestion, entity recognition, tax code application, and draft generation. The system is positioned to serve tax professionals looking to cut first-pass preparation time by up to 90%, freeing CPAs and enrolled agents for review, advisory, and client-facing work rather than data entry. With 70,000 or more users, the platform has achieved meaningful early adoption among solo practitioners and small tax firms looking to scale capacity without proportionally growing staff.\n\nTaxGPT has raised $4.6 million in funding from Rebel Fund and Y Combinator, reflecting its 2023 YC cohort roots. The company operates in a large, structurally inefficient market — US tax preparation alone is a $14 billion industry — competing against both legacy software (TurboTax, Drake) and newer AI-assisted tools. Its differentiation lies in the depth of autonomy offered: not AI-assisted tax prep but AI-first, with human review as the final step rather than the primary one.
Kalshi is a CFTC-regulated prediction market exchange where users trade on the outcome of real-world events — from elections to economic data to weather. HQ: San Francisco.
About
Kalshi is the first U.S. federally regulated event contracts exchange, authorized by the Commodity Futures Trading Commission (CFTC) to operate a marketplace where participants can trade financial contracts based on the outcomes of real-world events. Founded in 2018 by Tarek Mansour and Luana Lopes Lara, Kalshi went through a years-long legal battle with regulators to establish the legitimacy of event contracts as a regulated financial product in the United States. Its CFTC approval in 2020 created a new class of financial instrument for Americans who previously had no legal domestic venue for prediction markets.
