Solidus Labs builds crypto-native market integrity and risk monitoring solutions, anchored by its HALO suite for trade surveillance, transaction monitoring and threat intelligence. HALO is an all-in-one, real-time platform that services dozens of crypto and DeFi platforms, financial institutions and regulators, deploying over 50 proprietary market-abuse typologies. The platform monitors more than 1 trillion trading events per day across more than 150 markets and protects upwards of 25 million crypto market participants. Solidus reports massive demand for its solutions, has more than quadrupled its team since early 2021, and says it has experienced a 560% year-over-year revenue increase. The company is active in industry-regulator dialogue—founding the Crypto Market Integrity Coalition and hosting its DACOM Summit with SEC leadership participation. Future plans include accelerating threat intelligence capabilities, expanding R&D to address DeFi-specific use cases, and supporting financial institutions expanding into DeFi. Solidus Labs, a four-year-old New York-based startup, builds surveillance and risk-monitoring software that detects market manipulation across cryptocurrency trading platforms. It was founded by former Goldman Sachs electronic trading desk colleagues and is led by CEO Asaf Meir. The company originally sold primarily to exchanges, broker-dealers, OTC desks, liquidity providers and regulators but has seen rapidly growing inbound interest from DeFi actors such as automated market-making pools, lending networks, indexes and stablecoins. Its tools aim to identify risks including rug pulls, sandwich attacks, front running and flash-loan attacks. Solidus has declined to name customers publicly. Financially, the firm closed a $20M Series A six months ago and has just raised an additional $15M. The company says it intends to operate as an independent business. Solidus Labs provides surveillance and risk-monitoring software that detects market manipulation and other illicit trading behaviors on cryptocurrency platforms. Its detection covers volume and price manipulation including wash trading, spoofing, layering, pump-and-dumps and a growing set of crypto-native alerts. The company consumes private client data into proprietary detection models and surfaces insights and alerts through a dashboard as a subscription service. Customers include exchanges, broker-dealers, OTC desks, liquidity providers and regulators, and the company has a growing pipeline that has included platforms like Bittrex. Inbound demand increased roughly 400% over 2020, prompting hiring growth. Founded in 2017 by former Goldman Sachs electronic‑trading engineers, Solidus employs about 30 people, has raised $23.75 million to date (including a $20M Series A), and is doubling headcount while planning offices in Asia and Europe. Solidus Labs offers a web-based, machine learning–powered trade surveillance platform tailored to digital-asset markets. The platform is deployed with exchanges, broker-dealers, hedge funds and market makers across Europe, the United States and Israel. Its ML detection models reportedly reduce false positive alerts by at least 30% and include advanced case management, back-testing, investigative tools and integrated regulatory reporting. The company was founded by former Goldman Sachs engineers and positions its product to address novel manipulation schemes and evolving regulatory requirements. Solidus aims to expand its engineering and machine-learning teams as well as sales, marketing and customer success to meet growing demand from institutional digital-asset firms.

Mos launched in 2017 as an edtech platform connecting students to scholarships and has opened access to over $160 billion in financial aid for a community of more than 400,000 students. The company has helped students unlock over $1.5 billion in declared scholarship money and previously generated “a few millions” in ARR from fees for access to its scholarship pool. Mos has pivoted into a challenger bank, issuing a debit card with no overdraft fees, no late fees, no in-network ATM fees and no minimum balance, and it now monetizes primarily through interchange fees. The card saw rapid uptake: Mos says over 100,000 students opened accounts in the first quarter after launch and estimates it is the tenth largest neobank in the U.S. The startup plans to build a suite of paid products for students — including advisor consultations and premium banking features — and intends to grow with users beyond college. Founder Amira Yahyaoui emphasizes a community-first approach and a goal to become the incumbent bank for U.S. students, targeting expansion to millions more users. Mos provides a technology platform that checks over 30,000 eligibility criteria and aggregates access to the government's $135B in annual college financial aid into one application. The product pairs the eligibility-matching engine with a personal financial aid advisor to help students secure as much free funding as possible before taking on loans. Mos has been used by 200,000 students and their families. In response to COVID-19 the company launched a free, regularly updated guide with instructions and templates to help students with housing petitions, appeals, payment deferments, and financial-aid requests. The company was founded by Amira Yahyaoui with a mission to reduce student debt and increase access to government aid. Mos is backed by investors including Sequoia Capital and Arrive. Mos is a tech-enabled platform that helps students apply for and maximize federal and state financial aid using a short survey that matches applicants to more than 500 grant and scholarship programs while completing the FAFSA and state applications. The product charges a one-time fee of $149 and aims to deliver results in about 20 minutes; each case is reviewed by a Mos financial aid advisor who can negotiate with colleges for higher awards. The startup’s mission is to decrease American student debt (noted at nearly $1.6 trillion in 2018) and to digitize antiquated government systems that deter students from applying for aid. Mos plans a full-scale launch this summer and intends to tackle other countries’ college financial aid systems after scaling in the U.S. The company is led by Amira Yahyaoui, a Tunisian human-rights activist and founder of NGO Al Bawsala, who relocated to the Bay Area to build the business.
