Danny Brickman
Danny Brickman is the co-founder and CEO of Oasis Security, a New York and Tel Aviv-based cybersecurity company building the first enterprise platform for non-human identity management and agentic access management. A former Israel Defense Forces cyber R&D leader with 11 years of service and an Israel Defense Prize to his name, Brickman started Oasis in 2022 with Amit Zimerman to tackle the fast-growing security gap around machine identities, which now outnumber human identities by roughly 20 to 1. The company has raised about $195 million, backed by Sequoia, Accel, Cyberstarts and Craft Ventures.
Allen Control Systems
Allen Control Systems (ACS) is an Austin-based defense technology company building Bullfrog, an AI-powered autonomous robotic weapon station designed to detect, track and shoot down hostile drones. Founded in 2022 by three engineer-entrepreneurs, ACS uses passive machine vision and custom fire-control software to turn standard machine guns into precision counter-drone turrets, aiming to cut the cost-per-kill of a drone from expensive missiles down to a few dollars of ammunition. The company raised a $200M Series B in 2026 at a $2.2B valuation to scale manufacturing for the U.S. military and allied forces.

Founded in 2021 by former Frame.io leaders Sam Seely and Chris Bell, Knock lets product and engineering teams ship cross-channel notification workflows without building and maintaining an in-house system, and now powers messaging for companies like Vercel, Webflow, Amplitude, and Clay.

The company raised $6.6M seed led by Craft Ventures (with Jack Altman, 8VC, BoxGroup) and has reportedly raised roughly $20M total.

Endeavor
Endeavor is a San Francisco AI company building agentic software for the back office of American manufacturers and distributors. Its AI agents read the messy inputs these businesses actually run on - emails, PDFs, spreadsheets, phone calls - and turn them into automated order entry, quoting, accounts payable, and supply chain work inside existing ERP systems. Founded in 2023 by Wharton graduate Sahitya (Sami) Senapathy and backed by a $7M seed led by Craft Ventures, Endeavor counts industrial names like ClarkDietrich, Menasha, Viking, and Bridgestone Americas among its customers.
Gretchen Salyer
Gretchen Salyer is the founder and CEO of The June Care Company, a community-based childcare platform she launched in June 2021 after 15 years in technology, ending as a general manager at Intuit. Born out of pandemic childcare swaps she organized among neighbors, June Care connects parents who need care with vetted, background-checked stay-at-home parents who can earn income watching other children nearby. The company - whose name stands for Joining Up Neighbors Everywhere - has raised about $3.6M in seed funding led by Craft Ventures, and operates on Salyer's belief that the childcare crisis is solved by helping every family build its village.
Sami Senapathy
Sami (Sahitya) Senapathy is the solo founder and CEO of Endeavor AI, a San Francisco startup applying generative AI agents to the back-office and front-office grind of American factories and distributors. He started coding as a kid, built a FEMA disaster-response app in sixth grade, worked at the Air Force Research Lab at 16, interned at AWS, and shipped Palantir's first commercialized generative AI product in 2023 before launching Endeavor from his University of Pennsylvania dorm room and raising a $7M seed led by Craft Ventures.
Primer
Primer turns a company's ideal customer profile or account list into high-match B2B audiences and pushes them across consumer ad channels like Meta, Google, LinkedIn and Reddit, then measures real pipeline impact with website de-anonymization and holdout testing. Founded in 2019 and based in San Francisco, Primer resolves identities and runs enrichment waterfalls to deliver 3-5x better match rates than CSV uploads, helping growth and ABM teams prove advertising ROI instead of guessing at it.
David Sacks
David Sacks is a South African-born Silicon Valley operator turned venture capitalist and political power broker. He was PayPal's first product leader and COO, founded and sold Yammer to Microsoft for $1.2 billion, rescued Zenefits as interim CEO, and co-founded Craft Ventures, which manages billions in assets.

Discovering that synthetic identities with real 750+ credit scores were slipping through the financial system, they built SentiLink into a platform now serving 300+ financial institutions - including three of the top 10 US banks - having verified several hundred million applications. Named to Forbes 30 Under 30 in 2020, Blumenfeld holds a mathematics and economics degree from the University of Chicago and operates from Austin, Texas.
Paulo Martins
Paulo Martins is the Brazilian-born founder and CEO of Arena (arena.im), a San Francisco-based AI-powered community engagement platform that lets brands embed live chat, live blogs, and audience interaction tools directly on their own websites with a single line of code. After stints at NASA, Ubisoft, and Hulu — where he helped grow the streaming company from 100K to 7 million paying subscribers — Martins founded Arena in 2017 with a clear thesis: businesses should own their audience, not rent it from social platforms. By 2022, Arena had grown to 25,000 customers across 150 countries and closed a $13.6M Series A led by CRV, with backing from heavyweights like David Sacks, Des Traynor, and Olivier Pomel.

Fleet raised ~$45M total and grew from $1M to $60M+ annualized revenue in under a year. Nic is also a 3x YoungArts Award winner in photography and visual arts, a former pre-professional ballet dancer trained at Boston Ballet and San Francisco Ballet, and a QuestBridge Scholar from Columbia University.

Michael Martin
Michael Martin is the Co-Founder and CEO of Sidekick, a generative AI assistant purpose-built for real estate agents and brokerages. A Dartmouth-educated executive with a career spanning investment banking at Deutsche Bank and Apollo Global Management, digital agency leadership at Code and Theory, and proptech entrepreneurship, Martin co-founded Avenue 8 in 2020 as a tech-enabled mobile-first brokerage. When Sidekick's AI tooling proved more compelling than the brokerage itself, he made the bold call to shut down the brokerage entirely and go all-in on the software platform. Sidekick has raised $18M in funding, won back-to-back Webby Awards in 2024, and secured MLS partnerships covering over 120,000 real estate agents across the US.
