Alector Funding History

Before going public, Alector raised $195M in total equity funding, across 3 rounds.


Alector Funding Rounds

DateStageRaised FromRaisedValuationRev. MultipleDeal Summary
Jul-18Series EGV$133M—Alector, a South San Francisco-based biotechnology company, develops therapies for neurodegenerative diseases like frontotemporal dementia (FTD) and Alzheimer’s by leveraging an immuno-oncology-like approach to modulate immune responses in the brain. The company closed a $133 million Series E funding round on approximately July 25, 2018, with participation from GV (Alphabet's venture arm), Deerfield Management, AbbVie Ventures, Lilly Asia Ventures, MRL Ventures (Merck), Amgen Ventures, Dementia Discovery Fund, Foresite Capital, OrbiMed, Polaris Partners, Perceptive Advisors, and others including Section 32, Euclidean Capital, New Leaf Venture Partners, Casdin Capital, Federated Kaufmann Fund, and Mission Bay Capital. This round brought Alector's total funding to $195 million, following a $29.5 million Series D in 2016 led by Dementia Discovery Fund. Proceeds from the Series E will advance Alector's clinical programs, including Phase 1 trials for AL001 (for FTD), AL002 (targeting TREM2 for Alzheimer’s), and AL003 (targeting SIGLEC-3 for Alzheimer’s), with AL001 entering clinic first in healthy volunteers before asymptomatic patients using tied-in patient registries. The funding also supports expansion of its drug discovery platform and exploration into oncology treatments. Earlier, in October 2017, Alector secured a $205 million upfront partnership with AbbVie plus a $20 million equity investment. Prior rounds included a $32 million Series C in 2015 led by MRL Ventures. Alector positions its therapies as complementary to amyloid-beta and tau-targeting approaches, relying on a healthy immune system, amid a lack of novel treatments for neurodegenerative diseases.
Jan-16Series DAbbVie; Amgen Ventures; Dementia Discovery Fund; GV; Mission Bay Capital; MRL Ventures Fund; OrbiMed; Polaris Partners; Topspin Partners$30M—Alector LLC, a biotech company focused on pioneering immuno-modulatory therapies for Alzheimer’s disease and other neurodegenerative disorders, raised $29.5 million in a Series D financing announced on January 7, 2016. This followed a $32 million Series C earlier in 2015, bringing total capital raised that year to $62 million. The round was led by Dementia Discovery Fund, with new investors Amgen Ventures and AbbVie, and participation from existing investors including Merck Research Lab Ventures (MRL Ventures Fund), OrbiMed, Polaris Partners, GV (formerly Google Ventures), Topspin Partners, and Mission Bay Capital. The financing provided Alector with significant resources to advance its drug candidates into clinical trials and expand its discovery pipeline for neurodegenerative disorders. CEO Arnon Rosenthal highlighted the syndicate's composition as validation of Alector's approach, while Chairman Tillman Gerngross noted the cash position offered strategic flexibility for prioritization and partnering. Alector was actively hiring immunologists and neurobiologists at the time. Later, AbbVie deepened its involvement through a collaboration announced in 2019, paying $205 million upfront for options on two antibody targets, with potential future equity investment up to $20 million, though this post-dates the 2016 financing.
Sep-15Series CGV; Mission Bay Capital; MRL Ventures Fund; OrbiMed; Polaris Partners; Topspin Partners$32M—Alector, a US-based biotechnology company founded in 2013, develops immuno-modulatory therapies harnessing the body's immune system to treat neurodegenerative disorders like Alzheimer’s disease by targeting immune system failures in identifying brain pathogens. The company raised $32 million in its Series C financing round around September 2015, led by MRL Ventures Fund (Merck's corporate venture arm), with participation from GV (Google Ventures), OrbiMed Advisors, Polaris Partners, Topspin Partners, Mission Bay Capital, and others. The Series C proceeds were allocated to expand Alector's drug discovery pipeline, advance promising drug candidates into clinical trials, and hire additional immunologists and neurobiologists to roughly double its staff of about 12 at the time. Alector had identified 12 lead candidates for neurodegeneration treatments, planning to push two through preclinical development. The round exceeded initial targets, as the company aimed for $10 million but closed $32 million within two months, reflecting strong investor interest in its unified theory of neurodegeneration akin to immuno-oncology approaches. Following the Series C, Alector quickly pursued further funding, raising $29.5 million in a Series D round in early 2016 led by Dementia Discovery Fund, with new investors Amgen Ventures and AbbVie, and participation from existing backers including MRL Ventures, OrbiMed, Polaris, GV, Topspin, and Mission Bay Capital, bringing 2015 total capital to $62 million. This bolstered its cash position for independent advancement of candidates and strategic partnering. Alector continued hiring exceptional talent in immunology and neurobiology.
