How DSP Concepts scaled an audio platform from consulting shop to Series B

Executive overview

Most hardware companies reinvent audio signal processing from scratch, burning 90% of engineering time on chip-level code instead of innovation. DSP Concepts built Audio Weaver, a framework that abstracts that complexity so teams can focus on algorithms and ship in days rather than months.

The company grew from a 4-person consultancy to nearly 60 people, raised a Series B with BMW, Porsche, and MediaTek, and powers audio in Tesla, GoPro, and Bang & Olufsen products. The episode traces the tools — functional accountability, meeting cadence, culture enforcement, and structured hiring — that made that growth sustainable.

The standard-setter advantage: audio was a fragmented, artisanal market with no platform; the first company to become the default development environment wins the entire category.

The technology and the market opportunity

• Audio signal processing requires three non-overlapping skill sets: acoustic math, chip-level assembly coding, and tuning — most teams lack all three.
• Paul Beckman (MIT/Bose) spent 90% of his time on integration code, not invention; Audio Weaver was built to eliminate that bottleneck.
• Voice interfaces (Alexa, automotive, appliances) forced non-audio companies into audio development — creating demand for a standard workflow.
• Audio had no cross-industry platform standard; DSP Concepts positioned Audio Weaver as that standard, running across chip families and verticals.
• Investors from BMW, Porsche, and MediaTek signal that chip and OEM ecosystems are validating the platform thesis.

How Audio Weaver works in practice

• GoPro needed wind-noise reduction at 100 mph — no off-the-shelf algorithm existed; DSP Concepts built an iteration over one weekend that exceeded expectations.
• GoPro now runs a 6-microphone system tuned in-house using Audio Weaver's graphical interface, with staff whose entire job is field recording.
• Tesla Model S audio was spec'd in 2 pages (versus a typical 2,000-page automotive brief); Audio Weaver enabled rapid iteration to hit Elon Musk's approval bar.
• Both customers started dependent on DSP Concepts and graduated to running their own small teams — the platform creates customer capability, not dependency.

Building functional accountability

• From 2003 to 2015, DSP Concepts was a 4-person consultancy; headcount reached ~59 by early 2020.
• Early growth added bodies but not distributed ownership — accountability sat almost entirely with the two founders.
• Applying the Scaling Up functional accountability map forced explicit seat ownership beyond the technical core.
• The CEO role fell to Chin by default ("reluctant CEO") — recognising this early led her to seek coaching and impose structure before the team outgrew informal coordination.

Meeting cadence and execution discipline

• Before Scaling Up, meetings were ad hoc and unstructured — any topic could hijack any session.
• Introducing a fixed cadence required pruning over time: too many meetings were consolidated as the team learned to match meeting format to purpose.
• The hardest discipline was resisting open-ended strategy conversation when the go-to-market was still being figured out.

Culture and hiring

• Core values were defined early; the harder problem was enforcement — Chin cited the principle: fire someone, even at financial cost, to protect culture.
• Talent hired from process-mature companies often struggled in an environment still building its operating system; startup hiring requires weighting adaptability over pedigree.
• In hindsight: hire senior management earlier, not more individual contributors — spreading executive function sooner would have reduced founder stretch.
• With Series B funding, the 2020 growth plan focused on outbound sales, customer-facing engineers, and customer support — with smaller proportional growth on product.

Growth metrics and market resilience

• Revenue doubled in 2019 with almost no headcount increase; 2020 plan was to double both revenue and team size.
• All 2019 sales were inbound; the 2020 build-out was the first deliberate outbound motion.
• At the time of recording (early COVID), planned hires remained in place — DSP Concepts' products are used in R&D phases, which continue regardless of production slowdowns.
• Voice, conferencing, and remote-work audio all represent tailwinds in a downturn scenario.
