Company profile

researched Aug 2026

CTRL Labs (also written CTRL-labs) was a New York City-based startup developing non-invasive neural interface technology. Its core product concept was an electrode-studded wristband or armband that detects the electrical signals sent from the spinal cord to the muscles of the hand and forearm, then decodes those motor-neuron signals with machine learning so they can be used as input to a computer, phone, prosthetic, robot or virtual/augmented reality system [0][1][7]. Because the system reads the neural drive to muscles rather than overt movement, the company stated that users need not visibly move to generate a decodable intention [0][1].

The company's first announced product was the "CTRL-kit," a combined hardware and software development kit intended to be integrated into other organizations' technology stacks, with developer applications spanning accessibility tools, communication and messaging, medical monitoring, gaming, robotics and AR/VR [5][7]. Demonstrations described by investors included typing on a surface without a keyboard after a short calibration period, and playing an on-screen game with imperceptible finger movements while the hand rested flat [7].

CTRL Labs deliberately targeted mass-market consumer technology rather than medical or biotech applications, and co-founder Thomas Reardon has said the company turned down funding that would have positioned it as a biotech company [3]. On 23 September 2019 Facebook agreed to acquire the company; the team became part of Facebook Reality Labs [0].

Founding story

Thomas Reardon began his career at Microsoft at 19, where he worked on the Windows 95 team and built Internet Explorer [1][3][7]. He founded the wireless networking company Avogadro in 2000, sold it to Openwave in 2001 and served as CTO there, where his team developed an early mobile web browser, leaving in 2004 [7]. He then took a roughly twelve-year break from technology, earning an undergraduate degree in Classics at Columbia, a master's in neurobiology at Duke and a PhD from Columbia [3][7]. Reardon has said he saw decades of academic neuroscience as commercially unexploited, analogising the opportunity to Genentech's commercialisation of DNA research, and wanted a "billion-user" consumer outcome rather than a medical one [3]. He teamed with fellow neuroscience PhD Patrick Kaifosh, along with Timothy Machado and engineers, to found CTRL Labs in 2015 [1][5][7].

Business model

CTRL Labs sold or planned to distribute a hardware-plus-software neural interface product, the CTRL-kit, positioned as a component to be embedded into other companies' technology stacks and built on by third-party developers [5][7]. Sources do not describe pricing or revenue terms.

Not described in the available sources beyond the planned distribution of the CTRL-kit hardware and software to other organisations and developers [5][7].

Traction

Working prototypes were demonstrated publicly and to investors, including a wristband controlling a laptop and demonstrations of keyboard-free typing and game control [0][7]. The CTRL-kit was reported as shipping in the year of the Built In NYC article [5]. The company raised $67 million in total according to PitchBook data cited by Forbes [0], and one investor profile lists headcount at 51-100 [7]. Its ultimate outcome was acquisition by Facebook for a reported $500 million to $1 billion [0].

Latest developments

Facebook agreed to acquire CTRL Labs on 23 September 2019, with the team joining Facebook Reality Labs; Andrew Bosworth, Facebook's VP of AR/VR, said the company intended to scale the technology into consumer products [0]. Bloomberg reported a purchase price between $500 million and $1 billion [0]. Following the acquisition, co-founder Thomas Reardon served as VP and Head of Neuromotor Interfaces and Input and Interactions for Reality Labs at Meta, and is now a venture partner at Lux Capital [6].

β–ΈFull profile β€” market position, technology, go-to-market, geography, history, risks & controversies

Market position

CTRL Labs was one of several companies pursuing brain-computer and neural interfaces; Facebook itself had announced brain-computer interface plans in 2017 and funded related speech-decoding research at UC San Francisco [0]. Coverage positioned CTRL Labs' surface-electrode wristband as a less technically difficult and less risky alternative to direct-to-brain approaches [1]. It was described as a prominent New York deep-technology company backed by Amazon and Alphabet-affiliated investors [1][5]. Reardon expected a wider wave of neurotechnology companies to follow, which he described as only a "boomlet" [3].

Rather than implanting chips or reading directly from the brain, CTRL Labs used a non-invasive wearable band that intercepts motor-neuron signals at the muscle, which sources present as achieving comparable control functions without surgical risk [1][7]. Investors highlighted the ability to detect intended finger movement before muscles visibly fire, and decoding claimed to reach single-neuron resolution [7]. The company also differentiated strategically by refusing biotech/medical positioning in favour of a mass-market consumer product [3].

Technology

An armband or wristband fitted with multiple surface electrodes detects the electrical activity produced when signals relayed from the brain via the spinal cord reach the muscles of the arm and hand [0][1]. Machine learning and signal-processing algorithms decode this motor-neuron activity β€” described by one investor as resolving down to the single-neuron level β€” and translate it into digital control signals for a connected computer or device, enabling actions such as scrolling text, turning dials, selecting menu items, typing on a bare surface and controlling robots or prosthetics [0][1][7]. The approach is non-invasive, requiring no implanted electrodes [7].

Go-to-market

The company pursued a developer-first approach, offering the CTRL-kit hardware/software package for integration into third-party tech stacks and inviting developers to build neural control into their hardware or applications [5][7]. It also cultivated public visibility through demonstrations to investors and media of wristband-controlled typing and gameplay [0][7].

Initially developers and organisations integrating neural control into their own hardware and applications via the CTRL-kit [5][7], with an explicitly stated long-term ambition to reach mass-market consumers rather than medical or biotech niches [3]. Cited application areas include accessibility technology for the very young, elderly and disabled, medicine, education, robotics, productivity, communication, gaming and AR/VR [5][7].

Geography

Headquartered in New York City (Manhattan), New York, United States [0][1][7].

History

The company was founded in 2015 by Patrick Kaifosh and Thomas Reardon, both holders of neuroscience PhDs from Columbia University; Timothy Machado is also identified as part of the founding team [1][5]. Reardon assembled PhD colleagues and engineers to build a better human-computer interface [7]. Although the team started as neuroscientists with no intention of building hardware, they concluded early that they needed in-house hardware to prototype under controlled conditions, and spent the first couple of years building experimental "wind tunnel" rigs [3]. The company raised an $11 million first round and a $28 million round announced in 2018, with the latter led by Lux Capital and GV [4][5][7]. It was acquired by Facebook in September 2019 and folded into Facebook Reality Labs [0]; Reardon subsequently served as VP and Head of Neuromotor Interfaces and Input and Interactions for Reality Labs at Meta and later became a venture partner at Lux Capital [6].

Risks & controversies

Sources note that direct brain interfaces pursued by other companies are technically difficult and potentially dangerous, a risk CTRL Labs sought to avoid with a non-invasive wristband [1]. Reardon described substantial investor skepticism during fundraising, with many VCs saying they lacked a framework to analyse the company and some suspecting it was a personal ego project [3]. One commentary frames mind-reading input technology as initially sounding dystopian [5]. No litigation or regulatory issues are reported in the sources.
