AI infrastructure startup Trajectory has raised $40 million at a $300 million post-money valuation, led by Sequoia Capital with participation from Nvidia and Bessemer, according to The Information. The funding comes just two months after the company secured a $15 million seed round at a $115 million valuation. Founded in May by former Google DeepMind researchers Ronak Malde and Michael Elabd, alongside ex-Apple researcher Arjun Karanam, Trajectory focuses on continuous learning technology. The platform transforms user corrections, retries and edits into training signals, enabling AI models to improve after deployment. The company automates this process, allowing enterprises to continuously adjust models, prompts and harnesses based on real usage data. Clay, Decagon and Harvey are currently using or testing the technology.

Flagler Health raises $50M Series B led by Bessemer Venture Partners.

Credit: Flagler Health Flagler Health, a New York City startup, has raised $50 million to expand an AI platform built specifically for musculoskeletal (MSK) clinics. MSK care covers the treatment of bone, joint, and muscle conditions like back pain, arthritis, and sports injuries. Co-founded by Albert Katz, a former MSK clinic operator, and Dr. Leon Anijar, a physician, the company has built software that plugs into the electronic medical record (EMR) systems clinics already use, automating tasks from patient triage to billing. Doctors do not have to change how they work. Musculoskeletal conditions affect more than half of American adults and cost the U.S. healthcare system an estimated $420 billion per year, more than diabetes or heart disease. That makes MSK care one of the most expensive categories in American medicine. Yet the clinics providing that care are often overwhelmed by paperwork. According to Flagler, physicians spend nearly 75 percent of their time on tasks that do not generate revenue, including documentation and insurance coordination. The result is financial pressure on practices and burnout among the doctors who run them. "MSK is where the healthcare system's dysfunction is most visible. Shrinking reimbursements, administrative overload, inefficient triage - I watched it destroy clinician morale and clinic margins at the same time. This isn't a workflow problem. It's structural. The cost of running these clinics keeps climbing, and that cost is a major reason American healthcare is so expensive. It's unsustainable, and we're the only platform built to fix it at the root." Albert Katz, CEO of Flagler Health The Series B round brings Flagler's total funding to $63 million. Bessemer Venture Partners led the round, with participation from SignalFire, Alumni Ventures, Streamlined, 186 Ventures, Proof VC, Tribeca Ventures, and Offscript. Why Digital MSK Care Is Attracting Investor Attention The market for digital musculoskeletal care is expanding quickly. A recent industry report valued the global market at $3.8 billion in 2025 and projected it to reach $10.9 billion by 2032. Aging populations, rising rates of chronic pain, and growing demand from employers and insurers for alternatives to surgery are all fueling that growth. Much of the digital MSK market has focused on delivering care directly to patients through apps and employer benefit programs. Flagler works differently. Its platform is built for providers, the doctors, surgeons, and pain specialists who treat MSK conditions, and handles operational and administrative tasks that consume their time. The goal is to make the clinic run more efficiently, not to replace it. "What drew us to Flagler was rare: a founding team with exactly the right combination of healthcare operations experience, clinical authority, and AI expertise, all applied to one of the largest and most underserved markets in healthcare. The traction and ROI they've built in under three years reflects that. Flagler is the only full-stack platform purpose-built for MSK, and we believe it's on its way to becoming the AI-native operating system for every clinic in this space." Steve Kraus, Partner at Bessemer Venture Partners How Flagler Health Plans to Use the Funding Flagler will use the new capital to expand across MSK practices nationwide. In less than three years, the company has scaled to thousands of providers in more than 36 states. Clinics using the platform report an average of $164,000 in additional annual revenue per provider, according to the company. 87 percent of patients report improvement in pain, mood, sleep, or mobility. The company plans to position itself as standard operating software for MSK clinics across the country. Flagler says that practices using the platform early have seen stronger financial results and find it easier to attract and retain physicians, a persistent challenge in a specialty with high burnout rates. Who Built Flagler Health and What the Platform Does Albert Katz and Dr. Leon Anijar co-founded Flagler Health in 2022. Before starting the company, Katz studied at The Wharton School and served as CFO and COO of Spine and Wellness Centers of America, where he managed the day to day operations of MSK clinics. That experience with the administrative burden of running a practice, from hiring staff to managing insurance claims, directly informed how Flagler was designed. Dr. Anijar, the company's Chief Medical Officer, oversees the clinical side of the platform. In practical terms, Flagler's software sits inside the EMR systems that clinics already use. It manages the full patient journey, from initial triage through treatment, billing, and follow up communications, using AI trained on a large MSK patient data set. Clinics do not need new logins, extra training, or additional clicks. Providers describe it as hands-free and turnkey, running quietly in the background. The platform includes tools for patient engagement, billing and revenue cycle management, an AI call center, analytics, and care management. "Every doctor has wanted a tool like this and assumed it couldn't exist - something that genuinely improves patient outcomes without adding to their workload. With AI, that's no longer wishful thinking. Flagler makes the patient experience and the physician experience work together instead of against each other." Dr. Leon Anijar, Co-Founder and Chief Medical Officer of Flagler Health The Investors Behind Flagler Health's Series B Bessemer Venture Partners led the round. The firm has operated for more than a century and invests across enterprise software, healthcare, and consumer sectors. Joining Bessemer in the round were SignalFire, Alumni Ventures, Streamlined, 186 Ventures, Proof VC, Tribeca Ventures, and Offscript. Several of these firms, including SignalFire and 186 Ventures, also participated in earlier rounds. Before this Series B, Flagler had raised approximately $13 million, so the new round marks a significant increase in the financial backing behind the company.
