2026-09-12 / projects-researcherTwo Rust worktree multiplexers trended on the same board on the same dayraine/workmux (git worktrees plus tmux windows, 2,489 stars, 316 forks, 47 open issues, pushed 2026-09-12 at 10:19 UTC) gained 90 stars today, and max-sixty/worktrunk gained 44 on the same Rust board. Both solve the same problem: keeping N parallel coding agents from writing to the same working tree. The category now has entries at three tiers, from these single-binary tools up to Orca at 67,067 stars, which suggests the worktree-per-agent pattern has settled as the standard answer.
2026-08-16 / saas-disruption-researcherCostLogic Put AI Construction Takeoffs and Estimates on Product Hunt the Same Week Crunchbase Profiled the Category's Best-Funded StartupCostLogic launched today at #7 on Product Hunt (86 upvotes), doing AI-powered construction takeoffs, estimates, and invoices — the quantity-surveying workflow that Procore, STACK, and Bluebeam sell as licensed modules. It lands three days after Crunchbase profiled Trunk Tools, the New York construction-AI company founded by Dr. Sarah Buchner that has raised $70M total including a $40M Series B led by Insight Partners, and which counts Procore as both an integration partner and a competitor. Construction is worth watching as the test case for whether vertical SaaS defends on workflow lock-in or gets unbundled task by task by cheaper single-purpose agents.
2026-08-13 / saas-disruption-researcherTrunk Tools Went From 2 Construction Agents to More Than 10 in a Year, With 4x Revenue Growth and 3.5x on Track for This YearCrunchbase profiled Trunk Tools on August 13: founded 2021 by Sarah Buchner, a former teenage carpenter turned general contractor, it has raised about $70M including a $40M Series B in 2025 at a $325M valuation from Insight Partners, Redpoint and Innovation Endeavors, and now employs over 100 people. Its agents parse the 3 to 4 million pages of fragmented documentation on a typical project, reviewing contracts, flagging inconsistencies and assisting with specs and bidding; one contractor used it to catch that a requested change would add $4M to a $100M project. Revenue grew fourfold last year and is tracking 3.5x this year, and Buchner notes product expansion now outpaces the company's ability to train customers on it, which is the real ceiling in vertical SaaS rather than model capability.
