02 · Customer problem

Bad capture turns publishing into rescue work.

Creators, production teams, and media-tool builders lose time to filter chains, re-records, and audio that still cannot ship.

05 · Traction

Revenue arrived before outside capital.

A solo founder shipped the model, product, billing, and production API—and converted customers to recurring plans.

06 · Why now

More speech is published—and more valuable archives are waiting.

Demand signals, not a top-down TAM.

07 · Business model + GTM

Self-serve proves value; usage expands with the customer.

Initial buyer: independent podcast/video producers with difficult speech.

Expansion: teams add volume; developers embed restoration through keys, SDKs, webhooks, spend controls, and usage tooling.

Strategy: turn benchmark-led discovery and product proof into repeatable creator acquisition and API design partnerships.

08 · Competition

Diffio is the restoration specialist—not another editing suite.

AlternativeStrong fitDiffio distinction
Adobe PodcastFast browser cleanup inside Adobe’s creator ecosystem.Public hard-audio benchmark, model choice, and self-service API.
Descript Studio SoundTranscript-first podcast and video editing.Focused restoration without requiring an editing suite.
AuphonicLoudness standards, leveling, and broadcast workflows.Generative reconstruction for more severely degraded speech.
CleanvoiceFiller-word, silence, and podcast edit automation.Restoration quality is the primary product, with a self-service API.
Manual restorationExpert control for bespoke, high-value material.One-click throughput and consistent web/API workflow.
Do nothing / re-recordAcceptable when quality does not matter or capture can be repeated.Recovers value when the original moment cannot be recreated.

No single tool wins every workflow. Diffio focuses on difficult speech, self-service access, and web-to-API continuity.

09 · Technical moat

The core model is proprietary; the evidence is inspectable.

Diffio is not a wrapper around a hosted LLM.

01

Model ladder

Diffio 2.0 for fast, multilingual, high-volume work. Diffio 3.5 for maximum English reconstruction quality.

02

Evaluation know-how

Specialized data, restoration metrics, listening practice, and a public reproducible benchmark.

03

Production integration

Model training and inference operated in-house, with API, SDK, webhook, billing, and deployment skill.

04

Privacy by default

Uploads, outputs, and transcripts do not train shared models without affirmative opt-in. Users retain their content.

10 · Founder-market fit

A decade in signal processing, now pointed at one product.

Nathan Harmon built defense and commercial signal-processing systems, most recently RF geolocation and device identification at Northrop Grumman.

Today he trains models, runs GPU infrastructure, and ships Diffio end-to-end.

Next capability: add commercial distribution and partnership depth around a proven technical core.

11 · Milestones + Gemini Startup Forum fit
