Tandem

AI-driven molecular simulations for drug discovery

Overview

Company Does Not Provide H1B Sponsorship

TandemAI provides a cloud-based platform for pre-clinical drug discovery called TandemViz. It serves researchers at pharmaceutical companies and academic institutions by offering a suite of computational tools, AI, and supercomputing to simulate how drugs interact with proteins at the molecular level. The platform is accessed through a web interface, where users run dynamic physics-based molecular simulations to visualize drug-protein interactions and generate predictive models for efficacy and safety. TandemAI differentiates itself by offering a Discovery as a Service model that makes advanced drug-discovery tools widely accessible through subscriptions and service contracts, combining expertise from data science, physics, biology, and chemistry to speed up the research process. The company's goal is to democratize access to advanced computational tools, accelerate the discovery of therapeutic candidates, and improve the success rate of pre-clinical studies for patients in need.

Simplify's Take

What believers are saying

  • $22M Series A extension on November 19, 2025, funds AI models and wet lab expansion.
  • TandemViz integrates experimental data from external repositories, boosting research efficiency.
  • Prior $35M Series A in 2023 and $25M seed fuel computational platform scaling.

What critics are saying

  • Schrödinger dominates with superior simulations, capturing Takeda and Bristol Myers Squibb clients.
  • Exscientia nominates candidates 5x faster, eroding share via Sanofi and GSK deals.
  • Perpetual Medicines merger causes 20-30% client attrition from workflow disruptions.

What makes Tandem unique

  • TandemAI integrates AI, physics-based simulations, and in-house wet labs into TandemViz platform.
  • TandemAI offers Discovery as a Service with FTE pricing and SaaS licenses for seamless collaboration.
  • Merger with Perpetual Medicines on July 10, 2025, adds peptide drug discovery to small molecules.
