| Date | Stage | Investors | Raised | Deal Summary |
|---|---|---|---|---|
| Mar 2026 | Series B | RA Capital Management (lead); Nextech Invest; The Column Group; Lux Capital; Regeneron Ventures | $40M | - |
| Dec 2025 | Series B | Nextech Invest (lead); The Column Group (lead); Lux Capital; Regeneron Ventures | $120M | Atavistik Bio is a biotechnology company focused on discovering and developing precision allosteric therapeutics for serious unmet patient needs. The company leverages its proprietary AMPS (Allosteric Modulation Platform Strategy) platform, which integrates computational and experimental techniques to design small molecules targeting cryptic pockets, enabling selective targeting of disease-driving mutations. On December 18, 2025, Atavistik Bio announced a Series B financing round that raised $120 million, with a subsequent extension in early 2026 adding $40 million for a total of $160 million. The initial Series B was led by Nextech Invest and The Column Group, with participation from existing investor Lux Capital and new investor Regeneron Ventures. The company's lead program is ATV-1601, an oral AKT1-selective inhibitor being developed for hereditary hemorrhagic telangiectasia (HHT), a rare genetic bleeding disorder with no currently approved therapies. The company also has a JAK2 V617F mutant-selective inhibitor program targeting myeloproliferative neoplasms, a group of rare blood cancers. According to CEO Bryan Stuart, the HHT program was expected to enter clinical trials in the first half of 2026. The Series B proceeds are intended to advance both programs through clinical proof-of-concept milestones, with the company positioned to accelerate the translation of its precision allostery approach into patient-facing therapeutics. RA Capital Management led the Series B extension in early 2026, joining the original investors. As a clinical-stage biotech company with no marketed products, Atavistik Bio does not publicly disclose revenue, ARR, EBITDA, or post-money valuation figures. |
| Dec 2023 | Undisclosed stage | Nextech Invest; The Column Group; Lux Capital | $40M | Atavistik Bio is a biotechnology company developing precision allosteric small molecule therapeutics, focusing on selective inhibitors for rare diseases such as hereditary hemorrhagic telangiectasia (HHT) with ATV-1601, an oral AKT1-selective inhibitor, and JAK2 V617F mutant-selective inhibitors for myeloproliferative neoplasms (MPNs). In 2023, the company completed a $40 million Other Financing round featuring Lux Capital, Nextech Invest, and The Column Group, following prior Series A rounds of $60 million in 2021 (led by the same investors) and another $60 million in 2022. Later, in December 2025, Atavistik raised an initial $120 million Series B from Nextech Invest, The Column Group, Lux Capital, and Regeneron Ventures to advance its pipeline into clinical stages, followed by a $40 million extension in March 2026 led by RA Capital Management, bringing total Series B proceeds to $160 million. The funds support clinical development of ATV-1601 for HHT, which lacks approved therapies, and the JAK2 program for MPNs, aiming for superior efficacy and tolerability. Atavistik has raised approximately $340 million across five rounds to date, positioning it to expand its pipeline of high-quality programs targeting unmet needs in rare genetic bleeding disorders and chronic blood cancers. |
| Aug 2021 | Series A | The Column Group (lead); Nextech Invest; Lux Capital | $60M | Atavistik Bio is a biotechnology company developing selective allosteric small-molecule therapeutics targeting hard-to-drug proteins for diseases including hereditary hemorrhagic telangiectasia (HHT) and myeloproliferative neoplasms (MPNs) like polycythaemia vera and myelofibrosis. The company launched in August 2021 with $60 million in initial financing, matching the investors Lux Capital, Nextech Invest, and The Column Group as lead, indicative of a Series A round. Subsequent funding included a $100 million Series A conducted between 2021 and 2023, followed by a $120 million initial Series B in December 2025 extended by $40 million in March 2026 from RA Capital Management, bringing Series B total to $160 million. The proceeds from later rounds support clinical advancement of ATV-1601, an AKT1-selective inhibitor for HHT lacking approved therapies, and a JAK2 V617F mutant-selective inhibitor for MPNs, aiming for improved efficacy and tolerability over existing pan-inhibitors. |
