Virtustant is a remote staffing agency that places vetted bilingual professionals from Latin America with US companies. Founded in 2021 and headquartered in St. Petersburg, Florida, it has completed 2,000+ placements for more than 1,000 US client companies. The model is zero fee. Clients pay no recruitment or placement charge at any point and cover only their hire's all-in hourly rate, which starts at $7/hr and lets them save up to 70% against a comparable US hire. Only the top 1% of applicants are hired: of every 100, about 22 pass recruiter screening, 9 clear IQ, skills and English testing, 3 reach a client shortlist and 1 is hired. Clients receive a shortlist of 3 to 5 candidates within 48 hours of their first call and can have someone working within 72 hours. Virtustant handles contracts, payroll and the paperwork, and every placement carries a lifetime replacement guarantee. Virtustant ranked No. 661 on the 2026 Inc. 5000.

WiserBrand is an AI adoption partner for companies that need AI to pay for itself, not just look good in a board deck. We’ve spent 11 years in digital across North America and Europe, and the last four building with AI. We work with companies with 10 to 200 employees in professional services, construction, multi-location retail, and manufacturing. Most are under pressure to do something with AI and don’t have an in-house tech team to hand it to. It starts with a free intro call. From there, we put a fractional CTO, a business analyst, and a product owner on your team, working in your time zone. They identify where hours go and where mistakes cost money, from certified payroll to month-end close. Every fix gets a number before we build anything. Then the same team rolls it out in the systems you already use, one department at a time. A person still signs off on anything sensitive. We also build custom software and websites. Once your data is in order, we use it to run PPC and SEO, measured in revenue.
