Multiplier

YCombinator

Agent harnesses for asset managers

Multiplier helps institutional investors research stocks and manage their portfolios. We're live with six hedge funds, and our users spend 4+ hours a day in the platform. Investors who try "nearly every tool on the market," to quote a client of ours, "wind up with an unwieldy collection of fragmented point solutions." Those who focus on building a great setup with general agents are instead "signing up for a full-time job." So we deploy a platform called Multiplier that unifies structured data, unstructured data, AI work, human work, and tacit firm knowledge in one secure, governed, customized application. Our first vertical: independent equity funds with $250M-$5B of assets. They know AI is essential for staying relevant, but they don't have the time or talent to figure out what to do about it. But once we deploy Multiplier––"We used to spend 80% of our time gathering information and 20% of our time acting on it," said one customer. "Multiplier has flipped those percentages."

Robotic production capacity for the pharma manufacturing industry

The traditional manufacturing process for individualized drugs is extremely slow and expensive, because it is based on manual labor. At Multiply Labs, we believe that robotics is the only way to truly scale the production of individualized drugs - finally providing these life-saving therapies to the millions of patients who need them. We develop cloud-controlled modular robotic systems that manufacture individualized drugs, and we deploy these systems in the facilities of our pharma customers. This is pharma robotics as a service: we sell the robotic production capacity that our customers need to scale their next-gen individualized drugs.

On demand fuel delivery service in India

Why did we pick this idea to work on? India is a country with 200 mln vehicles (about the same number as USA) but one third the number of gas stations(60K) as compare to USA(160K), The consequence of odd number of fuel stations is long queues of vehicles at the gas stations to fill up, heavily congested Indian roads make it worse. Opening of 100K new fuel stations is practically & economically impossible in urban localities due to rocketing high land prices. And that's how the idea of mobile refueling was conceptualized by founders. Literally "bringing the gas stations to doorsteps". The problem of buying fuel is much more alarming in large volume consumer segments such as Vehicle fleet users like schools, cab rentals, freight logistics operators , tours and travels operators, hospitals, hotels, real estate etc who burn huge amount of dead mileage & loss of productivity while sending all fleet vehicles to gas stations to fill up. Additionally, India has a unique problem of Electricity blackouts. Current avg. is less than 18 hours of a day of electricity in Indian metro cities, which causes more than 20 mln household and commercial buildings running on backup generators which require Diesel. They cant bring the generators to gas stations either therefore they buy Diesel in jerry cans or barrels and transport unsafely. Our solution is solving the desperate & daily need of Indian consumers along with convenience. Do we have domain expertise in this area? Founder is ex veteran of Shell with 9 years of global experience, has complete understanding Oil marketing business. How do you know people need what you're making? We have over 5000 registred large volume customers who are waiting to be served. With our limited number of refueling vehicles ,we could serve max 1200 customers currently. We got all these customers without spending a penny in marketing and promotion. Zero sales efforts. Additionally, we have received over 400 franchisee requests across India where people want to offer mobile refueling service their town validating the demand.
