NYC-based commercial real estate lease comparables and analytics platform; raised $50M+; uses crowdsourced exchange model where brokers trade comp data for platform access.
CompStak is a commercial real estate lease comparables and analytics platform headquartered in New York City. Founded in 2011, the company has raised over $50M in funding and built a unique data exchange model where commercial real estate brokers, appraisers, and researchers contribute lease transaction data in exchange for access to CompStak's aggregated database of comps. This exchange model has enabled CompStak to build one of the most comprehensive collections of verified CRE lease comparables in the US market.\n\nCompStak's platform allows subscribers to search and analyze lease comps by submarket, building class, tenant industry, deal size, and lease term, with transaction details including effective rent, free rent periods, tenant improvement allowances, and base rent escalations. These metrics are notoriously difficult to obtain in commercial real estate, where lease terms are typically private. CompStak's analytics tools allow investors, lenders, and asset managers to benchmark their portfolio leases against market, underwrite acquisitions, and track rent trends in specific submarkets.\n\nCompStak serves commercial real estate brokers, lenders, private equity investors, and institutional owners who need reliable comp data for underwriting and market analysis. The company competes with CoStar's lease comps database but differentiates through its exchange model, which incentivizes brokers to contribute current transaction data faster than traditional research-gathering methods, and through its more granular lease detail available in core markets.
Open-source offline-first API client with git-native Bru file storage; solo-founded, declined 8 VC offers, competing with Postman and Insomnia for developers seeking privacy-respecting local API testing tooling.
Bruno is an open-source API client and testing tool — a lightweight, offline-first, git-friendly alternative to Postman and Insomnia — enabling developers to explore, test, and document APIs with collections stored as plain-text Bru files in the project filesystem rather than in cloud-synced proprietary formats. Created by a solo founder in 2022 and growing to a 9-person team by late 2024, Bruno operates with an unusual philosophy: the founder publicly declined 8 venture capital offers to preserve product freedom and build toward profitability, with the core Bruno client remaining free and open-source (MIT license) while the Golden Edition provides enterprise features for commercial revenue. Pro and Ultimate paid editions launched in 2024.
